In cash terms the typical NG33 home went from £52,000 in 1995 to £285,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 152%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2022. 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 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 (+28.4% on the year before); the weakest, 2011 (−21.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −8.1% | −10.2% |
| 5 years (since 2021) | −0.2% | −4.8% |
| 10 years (since 2016) | +3.5% | +0.1% |
| 20 years (since 2006) | +2.6% | −0.2% |
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.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 58% of the typed total.

How many homes change hands in NG33
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, 116 sales completed in NG33. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 222 sales a year before the financial crisis and 135 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
Reading the NG33 market
This is a thin market: 116 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. NG33 sits 8 of 29 in its area's price order, well inside the expensive end.
What homes rent for around NG33
The local authority for NG33 is South Kesteven, and its ONS average private rent currently stands at £838 a month (May 2026 figures). 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.
Set against the £285,000 median sold price, £838 a month is £10,056 a year, a gross yield of 3.5%: 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 another bedroom costs in NG
Real sold prices by size across the NG area, straight from the Land Registry record. The jump between sizes is local: in some areas a third bedroom adds a quarter to the price, in others nearly four fifths, so a national rule of thumb will mislead you here.

|---|---|---|---|---|---|
| Detached | — | £242,000 | £340,000 (+40%) | £500,000 (+47%) | £685,000 (+37%) |

Medians of recorded sales over the last four years, by built form and bedroom count. Sold homes carry no advertised bedroom count, so sizes are estimated from their EPC records; a small number of homes will sit one size out. Where too few homes exist to say anything meaningful, the cell is blank.
