The Gas Group started in London. The LTT brothers, our founders, are third-generation Londoners who learnt the trade in the boroughs they still serve today. From a Camden basement boiler to a Mayfair bathroom fit, we've worked it.
London is where most of our engineers live. That means short response times, deep knowledge of the housing stock (from Victorian terraces to ex-council flats to new-build apartments), and an actual understanding of London water pressure quirks (looking at you, anyone above the 4th floor in W2).
We cover all London postcodes — central, north, south, east, west, and the surrounding M25 areas. Whether you're in Wandsworth, Wood Green, Walthamstow, or Wimbledon, we've got engineers nearby.
