Average boiler repair costs. In the UK, the average boiler repair cost is between £100 and £500. This cost is influenced by the complexity of the fault, the parts required and regional labour charges.

A one-off gas boiler service can cost anything from £80 - £120. However, the average cost is £100. During a gas boiler service, a specialist Gas Safe engineer will inspect the boiler and controls to check for functionality.

Usually, a loss of heating, hot water or gas supply should be fixed within 1 working day. You could get compensation if it's not done in time. This is called the Right to Repair scheme. If you have another source of heating or hot water, there's no set deadline.
