Boiler installation starts from £1,800, which includes supply and fitting of an A-rated Vaillant, Worcester Bosch, or Ideal boiler, a full system flush, and a smart thermostat. Gas Safe installation certificate issued on completion. Next-day installation available.

Most boiler replacements take one day. Ralf arrives in the morning, removes the old unit, fits the new boiler, connects the smart thermostat, flushes the system, tests all radiators, and hands over the Gas Safe installation certificate — all on the same day.

Power flushing professionally removes sludge, rust, and magnetite from your central heating system. You need one if you have cold spots on radiators, the boiler is making banging or kettling noises, heating is slow, or gas bills have risen. Most boiler manufacturers require a clean system as a warranty condition. From £350.
