In cash terms the typical NG31 home went from £41,000 in 1995 to £220,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 147%, so homes here got dearer in substance, not only in cash. The real-terms peak came in 2020, and today's median remains roughly 4% under it: a 2020 buyer is still waiting to get that price back in today's money.
Year-on-year change in the NG31 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 2002 (+28.3% on the year before); the weakest, 2009 (−12.3%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +4.8% | +2.3% |
| 5 years (since 2021) | +4.1% | −0.7% |
| 10 years (since 2016) | +4.4% | +1.0% |
| 20 years (since 2006) | +2.9% | +0.1% |
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, 33% of the typed total. A detached home currently trades at £325,000 against £105,000 for a flat, 3.1 times the price.

How many homes change hands in NG31
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.
Month by month, five years back
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
Over the last twelve months of data, 541 sales completed in NG31. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 1,144 sales a year before the financial crisis and 604 a year over the last five. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.
What homes rent for around NG31
NG31 falls under South Kesteven, where the ONS puts the average private rent at £838 a month (May 2026 figures). Size sets most of the rent: one-beds average £580 a month here against £1,312 for four or more bedrooms.
Average monthly rent by size, South Kesteven
ONS Price Index of Private Rents, May 2026.
Set against the £220,000 median sold price, £838 a month is £10,056 a year, a gross yield of 4.6%: 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.

The "under comparable sales" label measures each asking price against real nearby sales of similar homes: an opening position for a conversation rather than a valuation. The home itself still needs looking at.

Bedroom by bedroom: NG prices by size
The Land Registry record, split by size: what each kind of home actually sold for across the NG 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 | — | £242,000 | £340,000 (+40%) | £500,000 (+47%) | £685,000 (+37%) |
| Semi-detached | £170,000 | £195,000 (+15%) | £235,000 (+21%) | £330,000 (+40%) | £462,500 (+40%) |
| Terraced | £154,000 | £165,000 (+7%) | £185,000 (+12%) | £250,000 (+35%) | £328,500 (+31%) |
| Flat | £118,800 | £151,000 (+27%) | £220,000 (+46%) | £397,500 (+81%) | — |
Built from the last four years of recorded sales by form and bedroom count. Bedroom counts are estimated from EPC records (the register carries none), so expect a small number of homes one size adrift. Sizes with too few homes to be meaningful are left blank.

These are medians of recorded sales, not valuations, and none of it is financial advice.
