“From my first enquiry regarding boiler replacement to the completion of the work, my mother was extremely satisfied with Wes. This included the unexpected repair of a damaged mains water pipe.”
“Wes has been my go-to professional for all kinds of plumbing works since 2021. Excellent service from start to finish: professional, punctual and very knowledgeable. A tradesman that actually cares and listens.”
“We have used Wes on more than one occasion and he has always provided a prompt, efficient service. When Wes says he has fixed a problem, it stays fixed.”
No call centre, no subcontractors. The person reading your WhatsApp is the person who turns up and the person who signs off the guarantee. Look for the black Transit.
Around £2,100 for a standard combi swap in Southampton, including the boiler, flue, fittings, and a day's labour. Larger systems or conversions cost more, we quote for free.
For most three-bedroom homes a 24–30 kW combi is right. Larger houses with two bathrooms or high hot-water demand may need 35 kW or a system boiler with a cylinder. We'll size it properly during the quote, not just match the old unit.
Worcester Bosch, Vaillant, and Ideal Logic+ all have strong track records and a Gas Safe install network. We'll recommend based on your home, budget, and warranty preferences rather than push a single brand.
Twelve to fifteen years if it's serviced annually. Skipping the service usually halves that and voids the warranty.
Most manufacturers require the system to be cleaned before fitting a new boiler, otherwise the warranty doesn't apply. We include a chemical flush as standard; a full power flush is £440 if the system shows heavy sludge.
