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 2019 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.
Old energy certificateThe latest certificate we matched is from 2011; certificates last 10 years. The seller needs a current one, and it may differ.
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.
