In cash terms the typical NP12 home went from £40,000 in 1995 to £220,000 in 2026, roughly 6 times the price. Even after inflation that is a real rise of about 153%: homes here genuinely became dearer, not merely more expensive on paper.
Year-on-year change in the NP12 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 (+31.6% on the year before); the weakest, 2009 (−13.0%). 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 2025, the last year both were recorded here, a detached home traded at £325,000 against £128,500 for a flat, 2.5 times the price.

|---|---|---|
| 1 years (since 2025) | +7.3% | +4.8% |

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.
Sales activity in NP12
The year-by-year sales count
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.
Over the last twelve months of data, 336 sales completed in NP12. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 572 sales a year before the financial crisis and 366 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
For renting purposes NP12 sits in Caerphilly. The ONS average private rent there is £742 a month (May 2026). The spread runs from £548 a month for a typical one-bed to £1,091 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Caerphilly
ONS Price Index of Private Rents, May 2026.
Set against the £220,000 median sold price, £742 a month is £8,904 a year, a gross yield of 4.0%: 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.
What kind of market NP12 is
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.

The price of an extra bedroom in NP
Real sold prices by size across the NP area, straight 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 | — | £285,000 | £370,000 (+30%) | £525,000 (+42%) | £683,000 (+30%) |

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. Blank cells mean too few homes for the figure to mean anything.
