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 2005 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.
LeaseholdAsk for the years left on the lease (under about 85 is a warning sign for lenders), the ground rent and how it rises, service charges for the last three years, any planned major works, and who the freeholder and managing agent are.
Flat in a blockAsk about the building's fire safety and cladding (an EWS1 form if the block is 11 m or taller), the reserve fund, and any restrictions on subletting, pets or alterations.
Article 4 directionSome work normally allowed without planning permission needs it here (Protected shopping frontage SF23: Walworth Road, East Street and Camberwell Road). Check before planning extensions or conversions.
Development planned nearbyThe council's brownfield register lists 2 sites of 50+ homes in this neighbourhood (largest: Morrisons, Walworth Road, 165 homes). Look up planning applications for anything near you.
Estimate is far from the last saleA lot has changed since it last sold, or the home has been extended or renovated. Rely on comparable recent sales and the survey.
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.
