Would not hesitate to recommend these guys to upgrade / replace a boiler. Work was done to a fantastic standard, and the quote they originally gave me was stuck to. A*!!

Frequently asked questions
We handle a full range of boiler types—including combi, system, regular (heat-only), gas, and electric boilers. Whether you’re looking for a high-efficiency combi for a residential upgrade or a robust system boiler for heavier usage, our Gas Safe‑registered engineers guide you to the best choice for your property’s size and heating needs.
Most standard boiler installations or replacements take 1–2 days, including initial assessment, removal of the old unit, fitting the new boiler, commissioning, and safety certification. Complex cases—like relocating the boiler or resolving old pipework issues—may take a bit longer, but you’ll always receive a clear, fixed‑price quote up front.
Yes—every boiler installation or replacement includes a Gas Safety Certificate (CP12), issued by our qualified engineers. This certificate is essential for legal compliance, insurance purposes, and maintaining manufacturer warranty. Once the work is done, we’ll also register it with the relevant authorities and handle documentation.
Absolutely. We offer 0% finance plans over 12 months, managed via Phoenix Financial Consultants. This lets you spread the cost of a new, energy-efficient boiler without any interest. Of course, all finance is subject to affordability checks.
Yes—we back all our boiler installations and replacements with a comprehensive warranty and aftercare plan. Aside from the manufacturer’s warranty (usually up to 10 years), we include an optional service-care package and annual boiler servicing. Plus, we provide emergency call‑out services year-round to keep your heating system fully protected.
