How much does a new boiler cost in Oxfordshire?
What changes the price of a boiler replacement, combi vs system boilers, grants to check, and how to compare installer quotes.
What changes the price
The boiler type and output, whether it's a like-for-like swap or moving location, new flue or pipework, a system flush, and controls such as a smart thermostat. Converting from a system boiler with a tank to a combi is usually more work than a straight swap.
Compare quotes fairly
Ask each Gas Safe registered installer for the make and model, warranty length, what's included (flush, filter, controls) and removal of the old boiler. A longer manufacturer warranty often depends on annual servicing.
Grants and alternatives
The government's Boiler Upgrade Scheme offers a grant towards a heat pump or biomass boiler instead of a gas boiler. Check current eligibility on GOV.UK before you decide.
