Questions about prices
Why do boiler prices vary so much?
The main things are the make and range, the size (kW output), the length of manufacturer warranty and the type of boiler. Moving the boiler, switching to a combi and extras like smart thermostats also change the total.
Will the price change on the day?
Not for the work you booked. The price is fixed for a standard like-for-like installation. If we find something extra is needed, such as a longer flue or extra pipework, we explain it and agree a price with you before doing it.
Is VAT included?
