Preston sits at the centre of a well-served Lancashire installer market, with companies covering the city alongside Blackburn, Burnley, Chorley, Lancaster and the Fylde coast. Much of rural Lancashire — the Ribble Valley and the Forest of Bowland in particular — sits off the mains gas grid, and homes there heated by oil or LPG qualify for the £9,000 Boiler Upgrade Scheme grant instead of £7,500.
£7.5k–£9k
Before you get quotes, check what grant you qualify for — most Lancashire homes get £7,500, off-grid oil/LPG homes now get £9,000. 60-second calculator →
