You may be able to get a free boiler replacement from the government if you already receive certain benefits such as Working Tax Credits, income support, Pension Credit Guarantee Credit Element, Child Tax Credits, and more. As for our service, currently, we offer free of charge survey plumbing or heating related as well as a 15% discount on our regular hourly rate. The offer applies to the elderly and disabled people in the UK. Every accepted quote gets 15% off. Our boiler quotes and survey for heating or plumbing are free of charge too, plus you will be provided a fixed and reasonable price by a qualified engineer. We do not provide our diagnostic for free, though.
