The price of a typical SG18 home, 1995 to 2026
Year by year: the median as it was recorded, and the same figure brought into today's money with ONS CPIH, which is where "did homes get dearer" actually gets answered. Hover shows each year; the legend isolates a series.

In cash terms the typical SG18 home went from £54,000 in 1995 to £366,800 in 2026, roughly 7 times the price. Adjusted for inflation it still comes to a real rise of roughly 212%, so homes here got dearer in substance, not only in cash. Measured in today's money the market peaked in 2018; the current median sits about 17% below that. Someone who bought at the 2018 peak has not yet seen that price back in real terms.
Year-on-year change in the SG18 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 2000 (+24.3% on the year before); the weakest, 2025 (−8.4%). 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 terraced homes dominate the record here, 31% of the typed total. A detached home currently trades at £470,000 against £230,000 for a flat, 2.0 times the price.

Annualised returns
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +5.4% | +2.9% |
| 5 years (since 2021) | +1.4% | −3.3% |
| 10 years (since 2016) | +2.7% | −0.7% |
| 20 years (since 2006) | +3.8% | +1.0% |
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.
The turnover behind the prices
Sales per year, counted
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
The monthly pulse, last five years
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
SG18 recorded 391 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 630 sales a year before the financial crisis and 474 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.
The rental side of SG18
For renting purposes SG18 sits in Central Bedfordshire. The ONS average private rent there is £1,247 a month (May 2026). A one-bed averages £862 a month here and a four-or-more-bed £2,039, so size does most of the work in setting the rent.
Average monthly rent by size, Central Bedfordshire
ONS Price Index of Private Rents, May 2026.
Against the £366,800 median purchase price, a rent of £1,247 a month (£14,964 a year) works out at a 4.1% gross yield, a ceiling figure that ignores letting costs, voids, maintenance and tax. Because rents are local-authority statistics, districts sharing the authority share the figure.
SG18 (Langford): the questions that come up
How much did a house sell for in SG18 (Langford)?
Are property prices falling in SG18 (Langford)?
Is SG18 (Langford) a good place to buy a house?
Are SG18 prices heading up or down?
That question has no honest answer, only evidence. The evidence: the median is up 7% over five years in cash but down 15% after inflation. Weigh the volume chart alongside the price one before deciding anything, and bear in mind every figure is a completed sale that reached the register weeks after completion.

The price of an extra bedroom in SG
What homes of each size actually sold for across the SG 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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £425,000 | £562,950 (+32%) | £790,000 (+40%) | £1,107,500 (+40%) |
| Semi-detached | £315,000 | £375,000 (+19%) | £450,000 (+20%) | £582,500 (+29%) | £785,000 (+35%) |
| Terraced | £290,000 | £342,000 (+18%) | £375,000 (+10%) | £510,000 (+36%) | £715,000 (+40%) |
| Flat | £205,000 | £270,000 (+32%) | £410,000 (+52%) | — | — |
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. Blank cells mean too few homes for the figure to mean anything.
