In cash terms the typical NG33 4 home went from £63,500 in 1995 to £340,000 in 2026, roughly 5 times the price. Even after inflation that is a real rise of about 146%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2021. The market now sits about 24% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the NG33 4 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 2010 (+38.1% on the year before); the weakest, 2011 (−27.2%). 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) | −2.9% | −5.1% |
| 5 years (since 2021) | −0.9% | −5.4% |
| 10 years (since 2016) | +2.5% | −0.9% |
| 20 years (since 2006) | +2.1% | −0.7% |
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.
The turnover behind the prices
Sales per year, counted
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.
NG33 4 recorded 19 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 102 sales a year before the financial crisis and 72 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.
Reading the NG33 4 market
This is a thin market: 19 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. Against the NG33 district median, NG33 4 sits 19% higher, marking it as a dearer pocket of the district.
What tenants pay around NG33 4
For renting purposes NG33 4 sits in South Kesteven. The ONS average private rent there is £838 a month (May 2026). The spread runs from £580 a month for a typical one-bed to £1,312 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, South Kesteven
ONS Price Index of Private Rents, May 2026.
£838 a month is £10,056 a year, which against the £340,000 median sold price makes a gross yield of 3.0%. 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.

Bedroom by bedroom: NG prices by size
What homes of each size actually sold for across the NG 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.
