How much is a landlord gas safety certificate?

Usually somewhere between £60 and £120 for a single appliance, more if there are several.

Price moves with where you are and how many appliances need checking. A flat with a combi boiler and nothing else sits at the bottom of that range. A house with a boiler, a gas fire and a gas hob sits nearer the top.

Some engineers charge less if you book several properties together, and most charge more for an out of hours visit. It is worth asking what the price covers, because a check is not the same as a service.
