The chart tracks the median Blackfen Road, Sidcup house price for every year with a recorded sale, from 1995 to 2026. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.

The highest yearly median on record for Blackfen Road, Sidcup is £505,000 in 2024; the lowest is £51,000 in 1995. Across the full 32-year record the cash median has moved from £51,000 to £339,700.

In 2026 money that first median is worth £113,244, so the real change over the whole record is +200.0% — about +3.61% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.

Over the last decade alone the difference is stark: -6.6% in cash against -33.1% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to Blackfen Road, Sidcup values — no mix of property types can flatter the number.

The mix of property types explains a large part of any area's median. Blackfen Road, Sidcup is dominated by the type at the top of this table, so its overall median leans that way.

114 of the sales on record are leasehold and 407 freehold — 21.9% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.

The median leasehold sale is £124,998 and the median freehold sale £220,000 — a gap of +76.0%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.

New builds sold for less than the median existing home — -75.0%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.

A further 52 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.

Every certificate carries an energy efficiency band as well as a floor area. Across Bexley, 40.7% of 110,275 certificates sit in bands A to C, and 3.0% in F or G — the bands that cost the most to heat and are hardest to mortgage.

The Office for National Statistics puts the mean private rent in Bexley at £1,531 a month as of Jun 2026 — £1,223 for a one-bedroom home and £1,858 for three bedrooms.

Against the median sale of £195,000 here, that rent is a gross yield of 9.42% a year. It is a measured figure rather than an assumption: a real local rent over a real local price, before any cost of ownership.

Police forces publish every recorded street-level crime. Within a mile of the centre of DA15, 225 crimes were recorded in Jun 2026: 86 violent, 2 burglary, 26 vehicle-related and 51 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is 1.3 times busier.

Against the 246,472 residents the 2021 census counted in Bexley, that is 0.91 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.

A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.

The 2021 census counted 246,472 residents in Bexley across 95,300 households. 70.0% of those households own their home and 30.0% rent — a split the sold record cannot show, because only owners appear in it.

10 state and independent schools have a DA15 postcode: 7 primary, 3 secondary. Catchment areas do not follow postcodes, so treat this as what is nearby rather than what a child would be offered.

The median across the whole archive is £157,500. Blackfen Road, Sidcup sits above that national figure — +23.8%.

Within Sidcup the street ranks 252 of 364 by median price, and its median is below the town figure of £215,000 (-9.3%).

Where an EPC floor area could be matched to the sale, the median works out at £2,832 per square metre, across 131 of the 521 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.

The full range on record runs from £28,000 to £1,000,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.

Blackfen Road, Sidcup sits in Bexley, in London.

The Office for National Statistics puts the median home in Bexley at 12.2 times median local earnings of £35,187 a year, measured to Sep 2025. Across England and Wales the same ratio is 7.6. That number, not the price alone, is what decides whether a place is within reach of the people who work in it.
