True Flame Heating provides Gas Safe registered plumbing and heating services across South East London and Central London. From our Sittingbourne base we cover Bromley, Bexley, Greenwich, Lewisham, Croydon, Orpington and out into Southwark, Lambeth, Wandsworth, Westminster, Camden and the City — typically with a same-day or next-morning visit.
London properties are some of the most varied in the country. We're equally at home working on Victorian terraces in Greenwich and Camberwell, ex-local-authority flats in Lewisham and Southwark, sealed-system installs in new-build apartments along the Thames, and high-end refurbishments in Kensington, Chelsea and Westminster.
Whether you're a homeowner with a broken combi, a busy landlord chasing same-day CP12 certificates across a London portfolio, or a letting agent who needs a reliable Gas Safe engineer on call, our team will turn up on time, quote up front and leave the property cleaner than we found it.
