How William Street, Kettering prices moved
The chart tracks the median William Street, Kettering house price for every year with a recorded sale, from 1995 to 2024. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 1990s | 4 | £33,500 | £74,386 |
| 2000s | 7 | £120,000 | £218,605 |
| 2010s | 3 | £172,000 | £242,520 |
| 2020s | 3 | £194,000 | £198,217 |
The highest yearly median on record for William Street, Kettering is £240,000 in 2022; the lowest is £32,000 in 1995. Across the full 30-year record the cash median has moved from £32,000 to £180,000.
In 2026 money that first median is worth £71,055, so the real change over the whole record is +166.6% — about +3.44% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +19.1% in cash against -27.9% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

Homes that sold twice
These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to William Street, Kettering values — no mix of property types can flatter the number.

What sells here
The mix of property types explains a large part of any area's median. William Street, Kettering is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Terraced | 129 | 73.7% | £145,000 | £16,500 – £375,000 |
| Semi-detached | 34 | 19.4% | £130,000 | £25,000 – £284,000 |
| Flat or maisonette | 10 | 5.7% | £77,500 | £24,000 – £111,000 |
| Detached | 2 | 1.1% | £230,000 | £230,000 – £250,000 |
Section 06
Ownership and new build in William Street, Kettering
10 of the sales on record are leasehold and 165 freehold — 5.7% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.
The median leasehold sale is £78,750 and the median freehold sale £143,000 — a gap of +81.6%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 10 | 5.7% | £78,750 |
| Freehold | 165 | 94.3% | £143,000 |
| New build | 5 | 2.9% | £129,950 |
| Existing home | 170 | 97.1% | £136,250 |
New builds sold for less than the median existing home — -4.6%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.
A further 3 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.
Section 09
How William Street, Kettering compares
The median across the whole archive is £157,500. William Street, Kettering sits below that national figure — -14.3%.
Within Kettering the street ranks 905 of 1505 by median price, and its median is below the town figure of £136,950 (-1.5%).
Where an EPC floor area could be matched to the sale, the median works out at £1,609 per square metre, across 37 of the 175 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.
The full range on record runs from £16,500 to £375,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.
