The Grantham property market recorded 1,142 residential sales in the 12 months to 31 May 2026, with a median sale price of £220,013. This places Grantham £1k above the Lincolnshire county median of £219,007, and £65k below the approximate UK median of £285,000.

Prices in Grantham have recorded a moderate decline, a year-on-year change of -4.3%. Within Lincolnshire, Grantham ranks 4th by price out of 8 principal towns, and 6th by transaction volume.

On a quarterly view, Grantham median prices moved from £240,000 in Q3 2024 to £218,000 in Q4 2025, a change of -9.2% over 5 quarters. The most recent quarter is excluded because HM Land Registry registrations for it are still incomplete.

South Kesteven District Council, the local planning authority covering Grantham, approved 116 residential planning applications and refused 42 in the last 12 months, with 103 still awaiting a decision. That is an approval rate of 73%.

Those applications propose around 2,672 homes, an estimated £585.1m of development value at local sale prices. Treat the unit total as an upper bound, since an outline permission and its reserved-matters application both count.

South Kesteven District Council covers more than one town in Lincolnshire, so these figures are authority-wide rather than specific to Grantham alone.
