Local Insight
London landlords must have a valid Gas Safety Certificate (CP12) for every rental property — fines for non-compliance can reach £6,000. When replacing a boiler, combi boilers are the most popular choice in London flats as they don't need a hot water cylinder. Always verify your engineer's Gas Safe registration at GasSafeRegister.co.uk before any work begins.
