Where these prices come from
Service prices come from the websites of Grantham heating firms and from booking sites such as Checkatrade and Rated People. The new boiler figure is from a UK cost guide, because local firms rarely publish one. Repairs are priced after the engineer finds the fault.
What pushes a price up
Oil boilers usually cost more to service than gas. For repairs, the price depends on finding the fault, the part needed and how easy the boiler is to reach. Evening and weekend visits can cost more.
How to get an exact quote

Questions people ask
Why do prices vary?
Firms price differently, and the boiler, the fuel and how easy it is to reach all change the time a job takes. Published Grantham service prices ran from £75 to £155 when we checked.
Is VAT included?
It depends on the firm, as smaller engineers are often not VAT registered. Ask whether the price includes VAT before you agree it.
Do I pay a call-out fee?
Some engineers charge one for repairs and urgent visits, and most include it in a service price. You are told before they set off.
