The average UK home cost 26% more in 2025 than in 2019. After inflation, though, that gain disappears: in real terms the average price ended slightly lower than where it started, and for flats the gap is wider still. A national average also says very little about your flat in Salford or your terrace in Swindon. If you want to know how to track your property value over time, without relying on a handful of listings, you need two things: an understanding of what actually moves the price, and a record of your own that still makes sense years later. Below you will find both, plus house price growth by region and for every local authority in Great Britain.
Why “what is my flat worth today?” has no single answer
Ask three people what your property is worth and you will get three different figures. Each can be reasonable, because each source measures something different:
| Source | What it measures | Where to find it | What to watch out for |
|---|---|---|---|
| Asking price | What the seller hopes to get | Property portals, agents' listings | Reacts quickly to sentiment and may differ from the final sale price |
| Sold price | What buyers actually paid | HM Land Registry Price Paid Data, UK House Price Index | Appears weeks or months after completion; the latest months get revised |
| Lender's valuation | The value of the security for a loan | When you buy or remortgage | Protects the lender, so it tends to be cautious |
| Formal valuation | Market value under a professional standard | A RICS-registered valuer | Costs money and is valid for one date |

Even a single source moves under your feet. The UK House Price Index is built from completed sales, so a sale only enters it once it has been registered. HM Land Registry therefore advises caution with the most recent months: they are provisional and get revised as more sales come in. If you note one valuation from listings and the next from sold prices, you will see “growth” or a “fall” that was caused by nothing more than a change of source.
A rule for your own records: every time you note a property valuation, write down where it came from. A figure without a source cannot be compared with anything three years later.
How prices have moved in your area
The national average is useful context, but the price of your property is set mainly by where it is. Below is the average price in every UK nation and English region, and in every local authority in England, Wales and Scotland, from 2019 to 2025. The figures come from the UK House Price Index, which is based on completed sales, not listings. Choose an area, compare it with the UK as a whole and share the link with whoever needs it.
The UK HPI adjusts for the mix of homes sold in each period, so a run of new-build sales does not distort it as much as a simple average would. It still describes a typical property in the area, not yours. Below regional level the monthly figures are a three-month moving average. Northern Ireland is shown at national level only and is published quarterly. Inflation: ONS Consumer Prices Index (CPI), annual average.

Browse a few areas and three things stand out that “house prices hit a record” headlines will not tell you:
- The most expensive is not the fastest growing. London has by far the highest average price (£562,057 in 2025), yet it grew the least of any region: 11% since 2019, which is a fall of 13% after inflation. London flats rose just 5%, a real fall of 18%. The North West grew 38% (8% above inflation) and Northern Ireland 45%.
- Prices do not rise in a straight line. After gains of 8% in 2021 and 9% in 2022, the UK average barely moved: +0.3% in 2023 and +0.6% in 2024 (annual averages). With inflation at 7% in 2023, that was a real fall of about 6.5% in a single year. In 2024, the average price fell in 199 of 349 local authorities. Anyone with only a purchase price and a guess would have missed it entirely.
- Flats have lagged houses. Across the UK, flats rose 14% between 2019 and 2025 against 26% for all property types, which is 11% below inflation. In 310 of 349 local authorities, flat prices did not keep pace with CPI. If your portfolio is mostly flats, the national headline overstates what happened to you.
| Local authority | Region | 2019 | 2025 | Change |
|---|---|---|---|---|
| Oldham | North West | £131,043 | £208,102 | +59% |
| Salford | North West | £151,798 | £231,384 | +52% |
| Rochdale | North West | £133,546 | £202,225 | +51% |
| Bolton | North West | £132,102 | £195,663 | +48% |
| Blaenau Gwent | Wales | £91,824 | £135,948 | +48% |
| United Kingdom | £212,434 | £267,281 | +26% | |
| Camden | London | £840,038 | £865,211 | +3% |
| City of London | London | £786,794 | £806,889 | +3% |
| City of Westminster | London | £1,013,009 | £1,028,751 | +2% |
| Southwark | London | £575,882 | £583,491 | +1% |
| City of Aberdeen | Scotland | £160,335 | £138,255 | −14% |

The top of the table is dominated by Greater Manchester, where prices started from a low base. The bottom is central London, where they started from a very high one, plus Aberdeen, the only local authority where the average price was lower in 2025 than in 2019. Treat the extremes with care: the City of London is a very small housing market, where a handful of sales can move the figures. For your own records, the pace of your area over several years is more useful than any single record-breaking figure.
What the market is saying now (as of October 2026)
The 2025 annual figures above are the latest complete year. The monthly releases show that growth has continued in 2026, but slowly:
- UK prices rose 1.4% in the 12 months to July 2026, to an average of £273,000. That is a provisional estimate, down from 1.5% in June (ONS).
- The regions are moving apart. The North East had the highest annual growth in England at 4.9%, while London prices were 3.3% lower than a year earlier. Northern Ireland, published quarterly, was up 9.2% in the second quarter of 2026.
- Rents are rising faster than prices. The average UK private rent rose 3.8% to £1,400 a month in the 12 months to August 2026, with London at £2,332 and the North East at £788.
The Bank of England's Financial Policy Committee limits how many new mortgages lenders can make at 4.5 times income or more to 15% of their lending, a check on borrowing relative to income. In April 2026 the PRA and FCA proposed removing that limit for individual lenders while keeping 15% across the market as a whole. Buy-to-let mortgages are underwritten under separate PRA standards, which look mainly at whether the rent covers the mortgage interest, usually tested at a higher, stressed rate. Either way, the current value of the properties you already own sets your LTV when you remortgage, and with it how much equity you have for the next step.
What moves the value of your property
The local average shows which way the market is going. Whether your property sits above or below it comes down to five things.
The immediate location
Transport (a new station or rail line, but also a planned bypass), planning applications nearby, schools and GP surgeries within walking distance, noise and parking. New development can bring shops and services, but it can also take away a view.
The building and the lease, not just the flat
With a leasehold flat, a buyer is also buying the building's future costs: the service charge, ground rent, planned major works such as a roof or cladding, and the remaining length of the lease. Lenders and buyers look closely at all of them. A high service charge reduces net yield, and an investor will price that into the offer.
Energy performance
Research for the government in 2013 found energy efficiency to be a key factor in the sale price of most homes in England. For landlords in England and Wales it is also a legal question: since 2020 a rented home has needed at least an EPC E, and from 1 October 2030 every tenancy will need a C under new EPC metrics, with landlords expected to spend up to £10,000 per property on improvements. A flat that cannot reach the standard will be harder to let, and that is likely to show up in what investors will pay for it.
Condition and improvements
Not every pound you put into a property comes back in its price. The difference between maintenance and improvement is explained below.
The tenancy
A let property has two kinds of buyer. An investor is buying an income, so a reliable tenant paying a market rent is a plus. Someone buying to live in wants it empty. If you are thinking of selling, keep that in mind when the tenancy comes up for renewal.
Improvement or maintenance?
Buyers take it for granted and will not pay extra for it.
- redecorating, small repairs
- replacing a tap, repairing the boiler
- servicing appliances
Most of all where the property lagged behind its neighbours.
- a new kitchen or bathroom
- an extension or a change of layout
- new windows, rewiring, better insulation
Record every improvement as a separate entry with the date, the cost and a description. That is the only way to tell later whether it paid off. The receipts matter for tax too: when you sell a property that is not your home, HMRC lets you deduct the cost of improvement works, such as an extension, when working out a capital gain, but not normal maintenance such as decorating. For the tax consequences in your own case, speak to a tax adviser.
What your property would be worth if it had moved with the market
Enter the year you bought and the price you paid, and see where the pace of your area alone would have taken it. If you have your own estimate of today’s value, add it: the difference shows whether your property is ahead of the market or behind it, and whether an improvement has shown up in the price.
The calculation multiplies your purchase price by the change in the area's average price between the year of purchase and 2025. The average knows nothing about the condition, floor or building, so the result is a yardstick, not a valuation. UK prices have moved a little further since 2025, so today's figure may differ.
How to keep a record that still makes sense years later
Your record does not need to be complicated, but it does need to be regular and sourced. Five items are enough:
- A starting point: the purchase price plus buying costs (stamp duty, legal fees, survey, initial works). Leave them out and you will overstate your gain.
- A valuation once or twice a year, always using the same method, for example recent sold prices of comparable homes nearby. Note the source every time.
- Improvements as separate entries, kept apart from routine running costs.
- Rental income and costs, so you see the return, not just the price.
- The mortgage balance. What you really own is your home equity: the value of the property minus the debt.
What such a record can look like (an illustrative example with made-up figures):
| Date | Value | Source | Note |
|---|---|---|---|
| 03/2021 | £210,000 | Purchase price | + £9,800 buying costs |
| 06/2023 | £232,000 | Lender's valuation | Remortgage at the end of the fixed rate |
| 01/2025 | £240,000 | Own market analysis | New bathroom 11/2024 for £7,500 |
| 09/2026 | £252,000 | Own market analysis | 4 sales on the street, HM Land Registry |

In England and Wales, actual sold prices are public. HM Land Registry’s Price Paid Data covers property sales registered since 1995 and has a free search tool, so you can look up what homes in your street or building sold for. Scotland and Northern Ireland have separate registers and are not included.
Yield and growth: two numbers that belong together
With a rental property, the price alone is only half the story. Your result is rent plus growth, and it pays to see them side by side. A rough guide from public averages: the average London rent of £2,332 a month (August 2026) against an average London price of £550,037 (July 2026) gives a gross rental yield of about 5.1%. In the North East, £788 a month against £166,943 gives about 5.7%. Both are before letting fees, service charges, voids, repairs and tax, and the rent and price averages cover different mixes of homes, so treat them as orientation only.
With rents rising faster than prices over the past year, the yield on the current value of a typical property has been edging up. The opposite also happens: when prices outrun rents, your percentage yield on today’s value falls even if you earn more in pounds. That is the moment to ask whether to hold, sell or move the capital elsewhere. How to work out net yield, cash flow and cash-on-cash return is covered in Rental yield: how to calculate whether your flat really pays off.
In a nutshell
- Do not mix asking prices and sold prices, and note the source of every valuation.
- The national average is context. The price is set by the local authority, the street, the building and the condition of the property.
- Prices do not rise in a straight line, and inflation eats part of the gain: in the UK, +26% in cash terms but −2% in real terms (2019–2025), and flats did worse.
- Record improvements separately so you know what came back.
- Track your equity (value minus mortgage) and rental yield alongside the price.
Annual property value review
Is your fixed rate coming to an end? Then the current value counts twice over: it sets your LTV, and with it the terms of the new loan.
How to track it in Assetli
For each property in Assetli you enter the purchase price, buying costs and your ownership share. You then add valuations to its history, each with a date and a source: your own estimate, a formal valuation or a market analysis. If you would rather not update it by hand, you can switch on automatic growth, either a fixed percentage a year or inflation plus a percentage you choose. That is an assumption, not a market price, so compare it with reality from time to time, for example with your area’s chart above.
Alongside the value you record rental income and costs, including improvements, and see both capital growth and yield. The property counts towards your net worth next to your accounts, investments and vehicles, so you can see how much of your wealth it makes up. And when you are weighing up another purchase, the property check helps you work through a listing in a structured way before you buy.
Assetli for landlords: the value of your properties over time, rental income, costs and mortgage balances in one place, next to the rest of your wealth. See how buy-to-let portfolio tracking works.
Frequently asked questions
How can I track my property value over time without a surveyor?+
Use the purchase price as your starting point, and once or twice a year compare it with the sold prices of similar homes nearby (HM Land Registry Price Paid Data in England and Wales, and the UK House Price Index for your area). Record the value, the date and the source each time. After a few years you will have a series that shows the real trend.
How often should I update the value of a rental property?+
Once or twice a year is enough for a let property, ideally in the same month and using the same method each time. Updating more often mostly adds noise.
How do I find out what a flat in my building sold for?+
In England and Wales, HM Land Registry publishes the price paid for registered sales since 1995 and offers a free search tool. Sales usually appear a few weeks after completion. Scotland and Northern Ireland keep separate registers that are not part of this data.
Is a formal valuation worth paying for?+
Not for routine tracking. It makes sense where you need a value that will stand up to scrutiny, for example for probate, a divorce settlement or a transfer into a company. When you remortgage, the lender arranges its own valuation.
Does every renovation add value?+
No. Maintenance keeps the value, while improvements can raise it, most of all where the property lagged behind its neighbours. Record improvements separately and compare them with later valuations. HMRC also treats them differently: improvement costs can be deducted when working out a capital gain, routine maintenance cannot.
Do property prices always go up?+
No. In 2023 the average UK price rose just 0.3% while inflation ran at about 7%, a real fall of roughly 6.5%. In 2024 the average fell in 199 of 349 local authorities, and in Aberdeen prices in 2025 were 14% below 2019. The long-term trend has been upward, but individual years and places can diverge sharply.
Conclusion
The value of a property over time is not one figure from a listing but a series of sourced records you can learn from. If you know your starting price, improvements, rent and mortgage balance, and compare them with the pace of your local area, you can decide on selling, remortgaging or buying again from your own data rather than from headlines. For the full picture of your wealth, see How to calculate your net worth.
If you would rather not keep piecing it together in a spreadsheet, add your property to Assetli. The first valuation takes a few minutes, and every later one joins its history.
