How Much Does a New Boiler Cost in Thorne?
What a replacement boiler costs in Thorne comes down to the job, not the postcode. Straight swap or system conversion, the boiler’s output, flue and gas pipe changes and the controls you pick – each one shifts the price. Like-for-like combi swaps start from £1,759 fitted, while Worcester Bosch Greenstar 4000 packages start from around £2,450. You agree one price up front, and that is what you pay. You won’t be asked for more money after installation.
