I needed advice about upgrading and moving the boiler from the kitchen to the airing cupboard. Jordan spent time taking through the options, answering my questions and gave me the reassurance that the job could be done without the pipe work showing. The outcome was excellent, really happy with the decision and quality of work and worth every penny! Would highly recommend Jordan and his team if you need any advice or work donePosted on Google![]()

Gas boiler installation in the UK typically costs between £1,800 and £3,500 for a straightforward combi replacement. More complex installations, system conversions, or larger boilers can range from £3,500 to £5,500. The final cost depends on boiler type, output, and installation complexity.
No. UK law requires all gas boiler installations to be carried out by a Gas Safe registered engineer. DIY gas work is illegal and dangerous, and can lead to gas leaks, carbon monoxide risks, invalid warranties, and insurance issues.
The correct boiler size depends on your property size, number of bathrooms, radiators, and hot water demand. Small flats typically need 24–27kW combi boilers, while larger homes may require 30–40kW or system boilers. A heating engineer will perform a heat-loss calculation to recommend the correct output.
The most common causes of boiler failure are worn internal components, low system pressure, pump or valve faults, and lack of annual servicing. Sludge or debris in the heating system can also damage parts over time.
Signs a boiler may need replacing include frequent breakdowns, expensive repairs, poor efficiency, inconsistent heating, unusual noises, and age over 12–15 years. If repair costs approach replacement cost, installing a new boiler is usually the better option.
