These terms are written in plain English, not legalese. Please read them before using PropertyData. If anything is unclear, ask us.
www.propertydata.co.uk ("our website") is operated by Liberty Tech Limited ("we", "our", "us"), a private limited company registered in England and Wales under company number 07689724, of registered address New Barclay House, 6-7 Citibase, 234 Botley Road, Oxford OX2 0HP. Our VAT number is 132027167. You can reach us at support@propertydata.co.uk.
These terms set out the basis on which you may use PropertyData, whether during a free trial or as a paid subscriber. "Use" includes registering for an account, browsing our website, using our browser extension, and accessing data through the PropertyData API. By using PropertyData you accept these terms. If you do not agree, you must not use it.
These additional terms also apply, and form part of your agreement with us:
PropertyData is sold to businesses and to people acting in the course of a trade, business, craft or profession. By opening an account you confirm you are doing so for those purposes and not as a consumer. Nothing in these terms affects any statutory rights you have if, despite this, you are in fact acting as a consumer.
We may change these terms at any time by updating this page, and will email you before any change that materially reduces what you get or increases what you pay. If you keep using PropertyData after a change takes effect, you accept the new terms.
An account is for one named individual. Sharing an account or its login details is strictly prohibited. Subscribers to the "Unlimited" plan may add additional users at £25 per user per month; you remain responsible for everything your additional users do.
Keep your login details confidential. You are responsible for all activity on your account. If you think anyone else knows your login details, tell us straight away and change your password.
You must give us accurate account and billing details and keep them up to date.
To start a 14-day free trial you must provide credit or debit card details, held securely by our payment provider, Stripe. We do not charge your card during the trial. When you sign up you choose a monthly or annual subscription period.
A trial gives you the plan you chose in full, subject to reduced allowances under our Fair Usage Policy and a total cap on API credits.
You can change your plan or cancel at any time during the trial in Settings, or by emailing us. Trials are strictly limited to one per person; you may not set up multiple trials using different email addresses.
We email you a reminder shortly before your trial ends. If you have not cancelled by the end of the 14 days, a paid subscription starts automatically and we charge your stored card for the first billing period.
Subscriptions are rolling, with a minimum term of one billing period. At the end of each period we charge your stored card and a successful payment extends your subscription by another period. We remind annual subscribers by email a few days before renewal. We do not send reminders before monthly renewals.
If a charge is declined we suspend your account and email you, then retry up to four more times over the following days before stopping. Updating your card in Settings restores your access as soon as a payment succeeds. A decline is usually nothing more than an expired or replaced card.
You can cancel at any time in Settings, or by emailing us. Your account stays open until the end of the period you have paid for. No refund is due for unused time, except as set out under "Refunds" below.
Instead of cancelling you may be able to pause your subscription. While paused you are not billed and cannot use your account or credits. You may pause for up to 6 months in any rolling 12-month period.
All prices are exclusive of VAT, which we add at the applicable rate where it is due. You are responsible for any other taxes or bank charges relating to your payment.
If we increase your subscription price, we will email you at least 30 days before it takes effect. You can cancel before then if you do not want to pay the new price.
We may offer discount codes giving a discounted first month or ongoing price. All discount codes have an expiry date and cannot be used after it.
Some purchases within PropertyData, such as Land Registry documents and site plans, are not billed immediately but grouped and billed as a batch. While unbilled these are your "pending payments".
We charge your stored card once your pending balance exceeds your limit, or with your next subscription payment. Annual subscribers are charged for outstanding pending payments once 30 days have passed since their last purchase. After a successful payment your pending balance resets to £0. You can see your pending payments and limit, or settle your balance, at any time in Settings.
Some plans include a monthly credit allowance. Credits are a subscription benefit, not a pre-purchased store of value, and cannot be redeemed for cash or transferred.
Credits are granted at the start of each billing period. Unused credits may roll over to the following month, up to twice your plan's monthly allowance; any excess is forfeited. If you cancel, you can use your credits until the end of the period you have paid for, after which they expire.
If you disagree with a charge, please contact us as soon as possible.
Subscription charges:
Letter sending and document purchases:
One-on-one training sessions:
Refunds of payments over £150 are subject to a cancellation charge of 3% of the payment value to cover our costs.
Refunding a subscription charge on an active account also closes the account, since we cannot keep your access open while refunding the payment that covers it. Refunds are issued to the card you paid with and usually reach it within 2-3 working days. They often show up as the original charge disappearing from your statement rather than as a separate credit, so it is worth checking for that before telling us one has not arrived.
For every user you refer to PropertyData, you (the referrer) and the referred user each receive a £75 bonus in your PropertyData Wallets.
If the referred user starts a monthly subscription, the bonus is issued when they make their third payment. If they start an annual subscription, the bonus is available towards their first payment, and the referrer receives theirs once that payment succeeds. If the referrer's subscription is no longer active when the bonus would be paid, neither party receives anything.
The scheme cannot be combined with the affiliate programme or any discount code. If a referred user also uses an affiliate link or discount code, that overrides the referral scheme and no bonus is awarded to either party.
The bonus is not redeemable for cash. We may withdraw it if we believe the scheme has not been used in good faith.
Wallet bonuses are earned through the refer a friend scheme, and may also be given at our discretion for other reasons, such as finding a bug or taking part in a review programme.
Your balance is shown in your Account area and is automatically offset against up to 50% of each subscription payment until it runs out. Wallet funds cannot be used against one-off payments such as plan upgrades or account reactivations, and are not redeemable for cash.
The content and data on PropertyData belong to us and/or our data suppliers, and are protected by copyright and other rights worldwide. A great deal of it we licence in from third parties, which is why the limits below exist: they mirror the limits our own suppliers place on us.
As a subscriber in compliance with these terms, you may use data, screenshots, extracts and PDF downloads from our website and API for any lawful purpose, commercial or non-commercial. That expressly includes using our data inside a product of your own, showing it to your own registered or paying customers, and putting it into reports you generate for them. You do not need our permission, a separate licence, a written agreement or a particular subscription tier to do any of that.
There is one restriction, and everything else follows from it: you may not publish, sell, license or distribute our data as a product or service that consists substantially of our data without enhancement or added value. The question we ask is whether our data is an input to something of your own making, or whether it is essentially the thing you are selling. In practice:
Permitted:
Not permitted:
No individual field is restricted. If we return it to you, you may show it to your users, and there is no limit on how many customers you have, how many records you display, or how many reports or exports you produce. We decide, acting reasonably, whether a use complies, and we would much rather you asked than guessed: if you are building something and are not sure which side of the line it falls on, describe it to us and we will tell you.
Screenshots, extracts and PDF downloads must not be altered, and must acknowledge PropertyData as the source. Attribution is not otherwise required, including for anything you build on our API, but it is always appreciated; ask us and we will send you a logo and suggested wording.
If you show our data to third parties, you alone are responsible for ensuring that you:
You are responsible for how you present or combine our data, and for decisions your users make based on it.
Some of our data includes URLs pointing to content hosted by third parties, in particular photographs on property listings. We hold no rights in that content, and these terms give you none. Obtaining any licence needed to display, copy, store or otherwise reuse it is your responsibility, and we recommend linking to the original listing rather than reproducing its imagery.
Your key and your trial
Your API key is your responsibility at all times, and you are responsible for every request made with it. Although our API supports CORS, we do not recommend exposing your key in publicly readable source code. You can regenerate your key in Settings at any time.
The 14-day API free trial is for development and testing only, and your key should not be used in production during it. If you are ready to go live sooner, ask us to accelerate your first billing period.
What you may build
Everything under "How you may use our data" above applies to the API. In particular, using the API inside a customer-facing product, including a paid, multi-tenant software-as-a-service product, is permitted on every plan under these terms and needs no separate commercial, redistribution or data licence. Your monthly credit allowance is the only limit on how much data you can retrieve; if you need more, move to a larger plan.
Caching: the 60-day rule
You may store what an API call returns for up to 60 days from the moment you retrieved it. At the end of the 60 days you must either delete that stored copy or replace it by making a fresh call. The 60 days runs from retrieval, and is not shortened by your subscription later ending.
The purpose of the limit is to stop the API being used to assemble a standing copy of our data that is then served to other people in place of calling us, which the licences we hold from our own data suppliers do not permit. A useful way to think about it: over time, showing a piece of current data to one of your users should broadly correspond to one call to our API for that data. The call does not have to happen while they are looking at it, and caching within the 60 days so that you are not repeatedly asking us for the same thing is exactly what the allowance is for.
We are not able to offer a longer caching period, on any plan, at any price, or under any separate licence.
What you may keep for longer than 60 days
The 60-day limit applies to our data held as current information. It does not stop you keeping a permanent record of what we told you and when, and it does not restrict what you build out of it. Provided you never present it as current, you may keep indefinitely:
Two conditions apply to all of that. It must be clearly marked as a historical observation and show the date it was retrieved. And it must not be used to answer a question about the present: if your product tells a user what a property is worth, what it is listed at, or whether it is still on the market today, that answer must come from a call made within the last 60 days, not from your historical record.
Listing links and photographs
Where the API returns a link to an original property listing, it is a forwarding link on the PropertyData domain rather than the portal's own address. You may show these links to your users, and we recommend that you do.
We hold no rights in listing photographs. The image URLs we return point to files hosted by third parties, and nothing in these terms permits you to display, hotlink, copy, store or create thumbnails from them. Whether you may use an image is a matter between you and whoever owns it, on which you should take your own advice. Omitting the image and linking to the original listing instead is the approach we recommend.
Bulk data
Because we licence much of our data in from third parties, we do not sell or licence out raw datasets, bulk extracts, data dumps or update feeds, and we cannot make an exception. The API, a request at a time, is how we make data available. We can sometimes take on a bespoke data project, such as appending our data to a list of addresses you supply, so tell us if that is what you need.
When your access ends
If you cancel, or we close your account, each piece of data you have already retrieved reaches the end of its 60 days as normal and must then be deleted. You may keep the historical records and derived material described above, and any reports you had already produced, but you may not use them to present current information, and you may not continue to serve our data to others without an active subscription.
Some features, including our chatbot George, use artificial intelligence to generate answers, summaries and suggestions. To provide them we send the relevant content, which may include your messages and account context, to our AI provider. Our providers do not use it to train their models. See our Privacy Policy for detail.
AI output can be wrong, incomplete or out of date. It is general information, never advice, and you must verify anything you intend to rely on. Do not enter information that is confidential or that you are not entitled to share, and do not use AI features to generate unlawful, misleading or abusive content.
We work hard to keep PropertyData available, but we do not guarantee uninterrupted access. We may suspend, withdraw or change any part of it, including features and content, without notice, and are not liable if it is unavailable.
Our data comes from many third-party sources. We give no warranty that it is up to date, complete or free from errors and omissions, and we are under no obligation to update it.
You are responsible for your own internet access and for the hardware, software and virus protection you use to reach PropertyData. We do not guarantee our website is free from bugs or viruses.
You must not:
Breaching the second or third of these is a criminal offence under the Computer Misuse Act 1990. We will report any such breach to law enforcement and disclose your identity to them, and your right to use PropertyData ends immediately.
You may link to our website provided you do so fairly and legally, and do not damage our reputation, take unfair advantage of it, or suggest an association or endorsement that does not exist. Our website must not be framed within another. We may withdraw linking permission without notice. PropertyData.co.uk is a UK trade mark of Liberty Tech Limited.
We may suspend or close your account, with or without notice, if you breach these terms, if a payment fails, or if we reasonably suspect fraud or misuse. Where the breach can be put right and the circumstances allow, we will tell you what is wrong and give you a chance to fix it first.
When your account closes, your right to use PropertyData and any credits end immediately, and any data you have cached must be deleted as set out under "Using the API" above. You remain liable for amounts already owed, including unbilled pending payments. No refund is due where we close your account because you breached these terms.
Export anything you want to keep before you close your account. Our Privacy Policy explains how long we keep your data afterwards.
Everything on PropertyData, including valuations, estimates and forecasts, is general information, not advice. It is not a valuation, survey, or investment, legal, tax or planning advice. Get professional advice before acting, or deciding not to act, on anything you find here.
We make reasonable efforts to keep our information current, but make no representation, warranty or guarantee that it is accurate, complete or up to date.
Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be excluded or limited. Subject to that, and to the extent the law allows, we exclude all conditions, warranties and other terms that might otherwise apply to PropertyData, whether express or implied.
We are not liable, whether in contract, tort (including negligence), breach of statutory duty or otherwise, and even if the loss was foreseeable, for any loss arising from your use of, or inability to use, PropertyData, or from reliance on anything in it. In particular we are not liable for:
Where we are liable despite the above, our total liability for all claims in any 12-month period is capped at the total amount you paid us in the 12 months before the claim arose, or £100 if that is greater.
We are not liable for any loss caused by a virus, denial-of-service attack or other harmful material that infects your equipment, programs or data because you used PropertyData or downloaded content from it or a linked website. Links to third-party websites are provided for information only; we do not control or endorse them and are not liable for your use of them.
We both comply with the UK GDPR and the Data Protection Act 2018.
For your account, billing and usage data, and for the property data we publish, we are the controller. Our Privacy Policy explains what we collect, why, and your rights.
Some of what we supply, such as title ownership information, includes other people's personal data. Once we have supplied it to you, you decide what you do with it and you are its controller from that point. You must have your own lawful basis for using it, and must handle it in accordance with data protection law.
Where you put other people's personal data into PropertyData, for example addresses you upload or contacts you send letters to, you are the controller and we are your processor. In that case we will: process it only on your documented instructions, which these terms and your use of the relevant feature constitute; keep it confidential and secure; use sub-processors only under equivalent obligations; help you respond to individuals exercising their rights and to any breach; and delete it on request or when your account closes, unless the law requires us to keep it. You confirm you have a lawful basis and any necessary consents before giving us that data.
We are not liable for failure or delay caused by something beyond our reasonable control, including failure of a data supplier, hosting provider or payment provider, internet or telecoms outages, cyber attack, fire, flood, epidemic, industrial action or government action. If it continues for more than 30 days, either of us may end your subscription and we will refund the unused portion of any period already paid for.
We may assign, transfer or sub-contract our rights or obligations under these terms. You may only do so with our written consent.
If any part of these terms is found to be unenforceable, the rest continues to apply. If we delay enforcing any right, we do not lose it. These terms and the policies they refer to are the entire agreement between us, and no one other than you and us has any right to enforce them.
If you have a complaint, email support@propertydata.co.uk. We aim to acknowledge within one working day and resolve within 14 days.
These terms, their subject matter and their formation are governed by English law, and the courts of England and Wales have exclusive jurisdiction.

Where does the raw data come from?
Property listings seen on rightmove.co.uk, zoopla.co.uk and onthemarket.com.
How often is the data updated?
The data is updated in near real-time.
What time period does the data cover?
This is a real-time market snapshot - the data covers currently listed properties. Once properties are removed from the portal, they are soon removed from this tab.
How is the raw data processed?
Duplicates from multiple sources are matched and reconciled as far as possible. Listings with obvious errors, where price or number or bedrooms appear out of range, are discarded.
What are the statistics used?
Averages shown are the interquartile mean, a type of average that is insensitive to outliers while being its own distinct parameter. The 80% range means that 80% of the listed properties fall inside this range.

Property listings seen on rightmove.co.uk, zoopla.co.uk and onthemarket.com.
How do you know the square footage of properties?
We use proprietary technology to read the square footage of properties from agent floorplans. Although we cannot determine the square footage for all properties, we can usually get sufficient coverage. Agents are sometimes known to inflate square footage, and this should be borne in mind as a weakness of this data.

Where does the raw data come from?
Property "price paid" data provided by the Land Registry.
How often is the data updated?
Once per month when released by the Land Registry, typically towards the end of each calendar month covering up to the end of the previous calendar month.
What time period does the data cover?
You can customise the time period using the filter at the top of the view. The default time period is up to 9 months back from today's date. The latest data covers the period up to 2026-06-30, although some sales that took place before this date may still be added in the coming months.

Where does the raw data come from?
Property "price paid" data provided by the Land Registry, and Energy Performance Certificate (EPC) data provided by MHCLG.
How do you know the square footage of properties?
We match the Land Registry data to EPC data provided by MHCLG. Due to the fact that not all properties sold have had an EPC and vagaries of addressing in the UK, we are not able to determine the square footage of all properties, but we can usually get sufficient coverage.
How often is the data updated?
The private paid data is updated once per month when released by the Land Registry, typically towards the end of each calendar month covering up to the end of the previous calendar month. The energy performance certificate database is updated monthly.

How is the raw data processed?
Duplicates from multiple sources are matched and reconciled as far as possible. Listings with obvious errors, where price or number or bedrooms appear out of range, are discarded. Yields are calculated by comparing only properties with the same number of bedrooms, e.g. 3-bedroom properties for rent with 3-bedroom properties for sale.
What is the yield calculation used?
The calculation used is (average_weekly_asking_rent * 52 / average_asking_price), expressed as a percentage. It is a top-line gross yield, meaning no expenses are considered.

Where does the raw data come from?
Quoting rent data is a proprietary data set based on the 2026 Valuation Office Agency (VOA) rateable values, combined with floor area data from MHCLG, adjusted for current market conditions.
What does "Quoting Rent" mean?
Quoting Rent reflects the estimated headline rent a property would achieve, based on official valuations adjusted for current conditions. This is the "face value" rent before any incentives such as rent-free periods, stepped rents or capital contributions are taken into account.
How is the floor area determined?
Floor areas are derived from MCHLG data. We use NIA (Net Internal Area) for retail, offices and leisure; GIA (Gross Internal Area) for industrial.
How often is the data updated?
The VOA data is based on the 2026 rating list, which is turn is based on 2024 comparables. This will be updated when a newer rating list is available. MCHLG data is updated regularly as new certificates are issued.
How is the raw data processed?
Multiple data sources are matched and reconciled. Properties are grouped by type, and outliers are excluded from averages.
What are the statistics used?
Averages shown are the interquartile mean, a type of average that is insensitive to outliers while being its own distinct parameter.
Where does the raw data come from?

Total Floor Area (TFA)
Total Floor Area is a measurement defined by MHCLG (Ministry of Housing, Communities and Local Government).
TFA includes all habitable rooms, kitchens, bathrooms, internal corridors, hallways, and built-in storage.
TFA excludes garages, external stores, and unheated conservatories.
Estimated value
This figure is our best estimate of the current value of this property.
It is calculated using the most recent transaction and the most recent internal area figures, combined with local market data and price indices.
Estimate confidence
The confidence level indicates how reliable our estimated value is likely to be for this property.
The property has sold recently, so the estimate is based on a known sale price adjusted for current market conditions.
The property has not sold recently, so the estimate relies more heavily on comparable local data and may be less precise.
Habitable rooms
Habitable rooms include any living room, sitting room, dining room, bedroom, study and similar; and also a non-separated conservatory. A kitchen/diner having a discrete seating area (with space for a table and four chairs) also counts as a habitable room.
A non-separated conservatory adds to the habitable room count if it has an internal quality door between it and the dwelling.
Excluded from the room count are any room used solely as a kitchen, utility room, bathroom, cloakroom, en-suite accommodation and similar and any hallway, stairs or landing; and also any room not having a window.
