In cash terms the typical DA15 8 home went from £70,500 in 1995 to £470,500 in 2026, roughly 7 times the price. Inflation explains only part of it: in today's money the rise is still about 207%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2022; the current median sits about 15% below that. Someone who bought at the 2022 peak has not yet seen that price back in real terms.
Year-on-year change in the DA15 8 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 (+22.0% on the year before); the weakest, 2009 (−8.5%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +4.6% | +2.1% |
| 5 years (since 2021) | +1.6% | −3.1% |
| 10 years (since 2016) | +2.7% | −0.7% |
| 20 years (since 2006) | +3.9% | +1.0% |
Compound annual growth of the median sold price; the real column deflates by ONS CPIH. Annualised figures smooth the cycle (the chart above shows the cycle), and past growth is a record, not a forecast.
Sales activity in DA15 8
Sales per year, counted
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
The register shows 62 DA15 8 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 341 sales a year before the financial crisis and 176 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.
What homes rent for around DA15 8
For renting purposes DA15 8 sits in Bexley. The ONS average private rent there is £1,528 a month (May 2026). The spread runs from £1,221 a month for a typical one-bed to £2,413 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Bexley
ONS Price Index of Private Rents, May 2026.
Set against the £470,500 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.

Moving up a bedroom in DA: the cost
The Land Registry record, split by size: what each kind of home actually sold for across the DA area. 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.
