Boiler Replacement Services

A new boiler should be a 15-year decision, not a 15-minute sale. That's why every Brainy Boilers replacement is installed by MPH Boilers — a family-run firm with 20+ years of engineering experience, Gas Safe registered (215540), and rated 4.8 from over 410 Google reviews.

Why Replace Your Boiler?

Modern boilers are significantly more efficient than older models. Here's what you can expect:

• Energy savings: new A-rated boilers run at 90%+ efficiency
• Lower running costs: an old, inefficient boiler wastes a share of every pound you spend on gas
• Reliability: new warranty coverage and fewer breakdowns
• Comfort: better temperature control and hot water performance

The Replacement Process

A proper replacement is more than swapping the box on the wall:

1. Quote: answer a few questions about your home and get a fixed-price quote online
2. Remote survey: a Gas Safe engineer from MPH Boilers confirms the specification over a Brainy Boilers Remote Survey before anything is booked in
3. Installation: your home protected with dust sheets, old boiler removed, new system fitted — usually in one day
4. Commissioning: the system is flushed, treated with inhibitor, pressure-tested and set up properly
5. Handover: the engineer walks you through the controls and answers your questions before leaving
6. Warranty registration: we register your boiler's warranty for you — nothing to post, nothing to forget
7. Aftercare: your paperwork, building regulations certificate and warranty documents follow on, and we're still here if you need us
