Pontllanfraith market report NP12 1, Blackwood
The NP12 1 (Pontllanfraith) house price history in full, 1995 to 2026, in cash and in today's money. Underneath every chart here sit 3,913 registered sales in NP12 1 (Blackwood) since 1995, the HM Land Registry record of what buyers really paid, with ONS figures covering rents. Nothing is a valuation, an estimate or an asking price.
Covers registered sales to 2026 and ONS rents for May 2026. Refreshed monthly as new sales reach the register.
In short: 35 registered 2026 sales put the NP12 1 (Blackwood) median at £235,000, up 32% on five years earlier, with a mean of £243,800, and by floor area homes here have averaged about £2,470 per square metre over the last five years. Everything rests on 3,913 completed HM Land Registry sales since 1995, refreshed monthly; valuations and asking prices play no part.
NP12 1 is a postcode sector: one group of streets inside NP12 (Blackwood). This is as local as the public record gets, but sector medians move on fewer sales than a district's, so expect the lines to be lumpier.

In cash terms the typical NP12 1 home went from £44,000 in 1995 to £235,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 146%, so homes here got dearer in substance, not only in cash.
Year-on-year change in the NP12 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 2003 (+46.7% on the year before); the weakest, 2023 (−12.1%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What NP12 1 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +5.6% | +3.2% |
| 5 years (since 2021) | +5.7% | +0.8% |
| 10 years (since 2016) | +7.0% | +3.4% |
| 20 years (since 2006) | +3.7% | +0.9% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Transaction volumes
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 35 NP12 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 169 sales a year before the financial crisis and 91 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
What tenants pay around NP12 1
NP12 1 falls under Caerphilly, where the ONS puts the average private rent at £742 a month (May 2026 figures). Size sets most of the rent: one-beds average £548 a month here against £1,091 for four or more bedrooms.
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 £235,000 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.
Reading the NP12 1 market
This is a thin market: 35 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.

Bedroom by bedroom: NP prices by size
The Land Registry record, split by size: what each kind of home actually sold for across the NP 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.
| 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%) |
