WHAT MOVES IT

Why two houses on one street differ by a thousand pounds.

Every figure on this page is supply and install including VAT, the same basis as the fitted prices on the brand comparison. The additions below sit on top of it.

Moving the boiler

New flue, new gas and water runs, and making good afterwards. Adds £400 to £900.

System flush

Often required for the warranty to stand. Adds £300 to £600, and skipping it can cost you the guarantee.

Losing the cylinder

A conversion is a two-day job, not a swap. Adds £300 to £700 plus the cupboard to make good.
