Range includes ±7% for the estimate itself. Effects are typical ranges, not this home's: a surveyor or local agent who sees it will do better. Work done before 2013 is already in the price. Evidence: of 573,662 homes we saw extended on their energy certificates (median +30 m²), the 123,110 that sold before and after grew a median 10.9% more than their neighbourhood: about a third of the extra space at the home's average price per m².

Questions to raise
Generated from the facts above, as prompts for your solicitor, surveyor or the agent. Not legal advice.
Older home (built 1900-1929)Consider a full building survey (RICS Level 3) rather than a basic one: older homes more often have damp, roof, wiring, drainage or structural movement issues, and past alterations may predate building regulations.
Sewage spills nearbyStorm overflows within 2 km spilled for about 1,732 hours in 2025 (Environment Agency). Worth knowing if you plan to swim, paddle or walk the dog along the local river or coast.
Resold within a yearIt changed hands quickly at some point. Ask what work was done, and for building-regulations sign-off and any warranties.
For every purchaseCommission a survey suited to the home's age and condition, check the title plan matches what you see on the ground (boundaries, access, parking), and ask about disputes with neighbours, rights of way and shared drives.
