DA15 prices by floor area

| 1996 | £72,000 | £151,845 | 591 |
| 1995 | £69,000 | £149,995 | 504 |
In cash terms the typical DA15 home went from £69,000 in 1995 to £465,000 in 2026, roughly 7 times the price. Adjusted for inflation it still comes to a real rise of roughly 210%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 14% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the DA15 median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 2000 (+21.6% on the year before); the weakest, 2009 (−10.6%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Annualised returns
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +1.8% | −0.6% |
| 5 years (since 2021) | +2.1% | −2.6% |
| 10 years (since 2016) | +3.0% | −0.4% |
| 20 years (since 2006) | +3.9% | +1.1% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of terraced homes dominate the record here, 39% of the typed total. A detached home currently trades at £774,500 against £285,000 for a flat, 2.7 times the price.

The turnover behind the prices
Sales per year, counted
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
Month by month, five years back
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
The register shows 313 DA15 sales across the most recent twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 671 sales a year before the financial crisis and 355 a year over the last five. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.
The rental side of DA15
DA15 falls under Bexley, where the ONS puts the average private rent at £1,528 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,221 a month here against £2,413 for four or more bedrooms.
Average monthly rent by size, Bexley
ONS Price Index of Private Rents, May 2026.
Set against the £465,000 median sold price, £1,528 a month is £18,336 a year, a gross yield of 3.9%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.

These asking prices come live from estate agents publishing feeds to HomesIndex, refreshed each Monday and Thursday. They are a sample of the market rather than its entirety, and an asking price is not a sale price.
Bedroom by bedroom: DA prices by size
What homes of each size actually sold for across the DA area, from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £450,000 | £600,000 (+33%) | £800,000 (+33%) | £1,100,000 (+38%) |
| Semi-detached | £341,500 | £410,000 (+20%) | £480,000 (+17%) | £600,000 (+25%) | £712,500 (+19%) |
| Terraced | £312,000 | £364,000 (+17%) | £410,000 (+13%) | £499,997 (+22%) | £630,000 (+26%) |
| Flat | £217,500 | £287,995 (+32%) | £339,997 (+18%) | — | — |
Built from the last four years of recorded sales by form and bedroom count. Bedroom counts are estimated from EPC records (the register carries none), so expect a small number of homes one size adrift. Sizes with too few homes to be meaningful are left blank.

How this page is made: the statistics are computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to address level; inflation adjustment uses the ONS CPIH index; rents are the ONS Price Index of Private Rents at local-authority level. Medians of recorded sales, not valuations. Nothing on this page is financial advice.
