Gas Boiler replacement costs

The average price of a traditional boiler, plus installation, is around £1,500 to £1,800. They can be bought from a variety of places, with the cost of installation typically included. Gas engineers will usually quote for the job as a whole without separating out a fee for removing the old boiler, so prices are similar to the cost of simply installing a new boiler.
