What Marlow Homeowners Say About Our Boiler Installation Specialists
Swapped our old combi for a new Worcester Bosch in Marlow. Gas Safe engineer, magnetic filter fitted, old unit taken away and the system flushed. £2,458 all in with a 10-year warranty. Heating and hot water back on the same day and the app control is a nice touch.
Moved from an ageing system setup to a new one in Marlow. Tidy pipework, Gas Safe registered, and they handled the Building Regs notification. £3,758 including the cylinder and a powerflush. Much better pressure across the radiators now.
Converted from a conventional setup to a combi in Marlow. Big job done over two days, Gas Safe certificate and Benchmark logbook handed over. £5,408 including the rerouting and removing the old tanks. Freed up the airing cupboard and the heating is far more efficient.
