Frequently Asked Questions
What changes the £1,800 starting price?
The £1,800 price is for a straight combi-for-combi swap, fitted in the same position, on your existing gas supply, with no pipework or flue rerouting. Moving the boiler, converting from a cylinder or system setup, or upgrading the gas supply may affect the price you’ll pay. We will confirm the final price of your quote after a free visit to survey your current heating set up.
Which warranty option should I choose?
We offer 2, 5, 10 and 15-year manufacturer warranties. The installed price covers the warranty you pick: £1,800 for 2 years, £2,200 for 5, £2,500 for 10. A 15 year warranty option is available on higher end boilers priced from £3,200, including VAT.
How long does a conventional-to-combi conversion take?
Most system conversions take 2 to 3 days. We will ensure you have access to running water as normal whenever possible.
