      Minimal disruption

      Fast boiler replacements, typically completed in one day

      A straightforward like-for-like combi boiler swap generally takes four to six hours to complete. LGS carries out the full process: disconnecting and removing your old boiler, fitting and commissioning the new unit, testing flue, gas pressure and controls, and walking you through the new system before we leave.

      Limescale protection included

      Scale reducers fitted to all combi boiler installations

      Hard water is a real issue across parts of Sussex. To protect your investment, LGS fits a scale reducer to every combi boiler installation as standard. This reduces limescale build-up inside the heat exchanger, extending the lifespan of the boiler and helping it maintain rated efficiency over years of use.
