In cash terms the typical GL20 home went from £58,000 in 1995 to £280,000 in 2026, roughly 5 times the price. Even after inflation that is a real rise of about 122%: homes here genuinely became dearer, not merely more expensive on paper. The real-terms peak came in 2020, and today's median remains roughly 18% under it: a 2020 buyer is still waiting to get that price back in today's money.
Year-on-year change in the GL20 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 (+21.4% on the year before); the weakest, 2008 (−8.1%). 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 detached houses dominate the record here, 33% of the typed total. A detached home currently trades at £445,000 against £147,500 for a flat, 3.0 times the price.

Compound annual growth of the median sold price; the real column deflates by ONS CPIH. Annualised figures smooth the cycle (the chart above shows the cycle), and past growth is a record, not a forecast.
How many homes change hands in GL20
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 monthly pulse, last five years
Registrations by month. The repeating sawtooth is seasonality, and the right-hand edge always dips because the register lags completions.
GL20 recorded 348 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 741 sales a year before the financial crisis and 367 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.
What tenants pay around GL20
For renting purposes GL20 sits in Tewkesbury. The ONS average private rent there is £1,020 a month (May 2026). A one-bed averages £696 a month here and a four-or-more-bed £1,663, so size does most of the work in setting the rent.
Average monthly rent by size, Tewkesbury
ONS Price Index of Private Rents, May 2026.
Against the £280,000 median purchase price, a rent of £1,020 a month (£12,240 a year) works out at a 4.4% 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.

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

|---|---|---|---|---|---|
| Detached | — | £329,250 | £450,000 (+37%) | £685,000 (+52%) | £1,050,000 (+53%) |

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. Where too few homes exist to say anything meaningful, the cell is blank.
