Valuations, estimates and asking prices appear nowhere in it.
Sales recorded to 2026; rents are ONS figures for May 2026. The page rebuilds with each monthly release.

The figures cover 3,480 sales recorded by HM Land Registry since 1995 and refresh with each monthly release: completed sale prices, not valuations or asking prices.
A postcode sector like NP12 0 is a single group of streets within NP12 (Blackwood), the finest slice the public record supports. Fewer sales stand behind each figure than at district level, so the lines jump about more.

In cash terms the typical NP12 0 home went from £37,000 in 1995 to £237,000 in 2026, roughly 6 times the price. Adjusted for inflation it still comes to a real rise of roughly 195%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2020. The market now sits about 11% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the NP12 0 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 2020 (+46.4% on the year before); the weakest, 2013 (−27.7%). 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) | +19.1% | +16.3% |
| 5 years (since 2021) | +7.0% | +2.1% |
| 10 years (since 2016) | +6.2% | +2.7% |
| 20 years (since 2006) | +3.3% | +0.5% |
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
How many homes change hands
Each bar is a year's recorded sales. 2008's dip is the financial crisis, and the newest bar always grows for a while as late registrations arrive.
Over the last twelve months of data, 43 sales completed in NP12 0. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 142 sales a year before the financial crisis and 88 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 NP12 0
For renting purposes NP12 0 sits in Caerphilly. The ONS average private rent there is £742 a month (May 2026). A one-bed averages £548 a month here and a four-or-more-bed £1,091, so size does most of the work in setting the rent.
Average monthly rent by size, Caerphilly
ONS Price Index of Private Rents, May 2026.
£742 a month is £8,904 a year, which against the £237,000 median sold price makes a gross yield of 3.8%. 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.
The shape of the NP12 0 market
This is a thin market: 43 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. Expect volatility in the annual figures: swings past ten per cent show up repeatedly above, and they usually reflect the mix of homes sold in a given year rather than genuine repricing. Within NP12, this sector trades 8% above the district median: one of the dearer corners of its district.

Bedroom by bedroom: NP prices by size
What homes of each size actually sold for across the NP 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 | — | £285,000 | £370,000 (+30%) | £525,000 (+42%) | £683,000 (+30%) |
| Semi-detached | £200,000 | £215,000 (+7%) | £250,000 (+16%) | £320,000 (+28%) | £417,500 (+30%) |
| Terraced | £160,000 | £155,000 (-3%) | £170,000 (+10%) | £225,000 (+32%) | £293,750 (+31%) |
| Flat | £120,000 | £137,000 (+14%) | £200,000 (+46%) | — | — |
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.
