In cash terms the typical CA20 1 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 1 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.
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% |
| 10 years (since 2016) | +1.8% | −1.6% |
| 20 years (since 2006) | +2.4% | −0.4% |
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.
Sales activity in CA20 1
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.
The register shows 20 CA20 1 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 74 sales a year before the financial crisis and 52 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
The rental side of CA20 1
CA20 1 falls under Cumberland, where the ONS puts the average private rent at £666 a month (May 2026 figures). Size sets most of the rent: one-beds average £496 a month here against £1,071 for four or more bedrooms.
Average monthly rent by size, Cumberland
ONS Price Index of Private Rents, May 2026.
£666 a month is £7,992 a year, which against the £202,500 median sold price makes a gross yield of 3.9%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.
What kind of market CA20 1 is
Only 20 sales completed here in the last twelve months of data, which makes CA20 1 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint. 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.
CA20 1 (Sellafield): the questions that come up
How much did a house sell for in CA20 1 (Sellafield)?
Are property prices falling in CA20 1 (Sellafield)?
Is CA20 1 (Sellafield) a good place to buy a house?
Where do CA20 1 prices go next?
Prediction is not this page's business. Its business is the record, which says: the median is up 7% over five years in cash but down 16% after inflation. Read the volume chart with the price chart before acting on either, remembering that registrations trail the deals themselves by weeks.
The price of an extra bedroom in CA
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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £220,000 | £300,000 (+36%) | £430,000 (+43%) | £523,000 (+22%) |
| Semi-detached | £142,000 | £155,000 (+9%) | £205,000 (+32%) | £265,000 (+29%) | £357,500 (+35%) |
| Terraced | £105,000 | £115,000 (+10%) | £132,500 (+15%) | £184,000 (+39%) | £255,000 (+39%) |
| Flat | £92,000 | £124,950 (+36%) | £165,500 (+32%) | — | — |
Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Where too few homes exist to say anything meaningful, the cell is 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.
