Sellafield market report CA20, Seascale
The CA20 (Sellafield) house price history in full, 1995 to 2026, in cash and in today's money. The raw material for this page is 1,956 HM Land Registry entries for CA20 (Seascale), going back to 1995: each an actual purchase at an actual price. Rents come from the ONS. Valuations, estimates and asking prices appear nowhere in it.
Sales recorded to July 2026; rents are ONS figures for May 2026. The page rebuilds with each monthly release.
In short: 20 registered 2026 sales put the CA20 (Seascale) median at £202,500, up 7% on five years earlier, with a mean of £223,000, and by floor area homes here have averaged about £2,080 per square metre over the last five years. Everything rests on 1,956 completed HM Land Registry sales since 1995, refreshed monthly; valuations and asking prices play no part.
The postcode district CA20 covering Seascale, Sellafield, Gosforth sits in Seascale. A district is the workhorse unit for reading a market: local enough to be meaningful, busy enough that the medians rest on a steady flow of sales.

In cash terms the typical CA20 home went from £48,500 in 1995 to £202,500 in 2026, roughly 4 times the price. Inflation explains only part of it: in today's money the rise is still about 92%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2005; the current median sits about 20% below that. Someone who bought at the 2005 peak has not yet seen that price back in real terms.
Year-on-year change in the CA20 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 2004 (+42.7% on the year before); the weakest, 2001 (−17.5%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of semi-detached homes dominate the record here, 40% of the typed total. In 2018, the last year both were recorded here, a detached home traded at £192,500 against £78,500 for a flat, 2.5 times the price.

Annualised returns
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −5.8% | −8.0% |
| 5 years (since 2021) | +1.3% | −3.4% |

Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
Transaction volumes
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 last five years, month by month
Registrations by month. The repeating sawtooth is seasonality, and the right-hand edge always dips because the register lags completions.
CA20 recorded 52 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 74 sales a year before the financial crisis and 52 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.
Rents around CA20
For renting purposes CA20 sits in Cumberland. The ONS average private rent there is £666 a month (May 2026). A one-bed averages £496 a month here and a four-or-more-bed £1,071, so size does most of the work in setting the rent.
Average monthly rent by size, Cumberland
ONS Price Index of Private Rents, May 2026.
Set against the £202,500 median sold price, £666 a month is £7,992 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.
How CA20 trades
This is a thin market: 52 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict. The record here is jumpy: year-on-year moves of ten per cent or more are common in the chart above, mostly a function of which homes happened to sell rather than the market lurching.

Bedroom by bedroom: CA prices by size
What homes of each size actually sold for across the CA area, from the Land Registry record. How much a size step costs is a local fact: the third-bedroom premium runs from about a quarter to nearly four fifths depending on the area, and national rules of thumb miss it.

|---|---|---|---|---|---|
| Detached | — | £220,000 | £300,000 (+36%) | £430,000 (+43%) | £523,000 (+22%) |

Medians of recorded sales over the last four years, by built form and bedroom count. Sold homes carry no advertised bedroom count, so sizes are estimated from their EPC records; a small number of homes will sit one size out. Blank cells mean too few homes for the figure to mean anything.
