A boiler standard service will cost 65 including vat and that includes cleaning out a magnetic system filter (if fitted). Your service package will include a full inspection as well as flue gas tests. However, if there are problems with your boiler, the cost of parts and labour to fix your boiler won't be included in the price. We recommend getting your boiler serviced every 12 months. In fact, most boiler manufacturers won't honour their warranty unless your boiler has been serviced by a Gas Safe Engineer every 12 months.
