New boiler. Lower bills.
Stop burning money on an inefficient heating system — a new A-rated boiler pays for itself faster than most people think.
According to the Energy Saving Trust, upgrading from an old G-rated boiler to a new A-rated model can significantly cut your annual gas bill.
Add a smart thermostat — included as standard with our Premium package — and you could reduce heating costs by a further 10% or more.
Your old boiler is costing you more than you think
Wasting energy, not just money
An ageing boiler wastes up to 35% of the energy it uses — hundreds of pounds a year not heating your home, just burning money.
Breakdowns don't warn you
Boilers over 10 years old don't slow down — they fail suddenly. Freezing morning, no heating, no hot water. It's not if, it's when.
Repair bills that keep coming back
One call-out becomes two. Every pound spent on repairs is a pound wasted on a system already past its life.
Old means risk, not just inefficiency
Carbon monoxide leaks, pressure faults, ventilation failures — real risks that increase every year a boiler runs past its lifespan.
Good install slots don't last
St Albans engineers book up fast, especially heading into winter. Don't wait until you're without heating to act.
Not sure which boiler you need?
We’ll assess your home and recommend the right one — no pressure, no upselling.

Hertfordshire homeowners love us
Real reviews from real installations across St Albans, Harpenden, Watford and beyond.
They came to my rescue in a genuine emergency and installed a new boiler at incredibly short notice, just before Christmas. From Matt to Jared and apprentice Oscar, they were professional, prompt and genuinely caring — outstanding service from start to finish.
We needed a replacement boiler and PHP were quick and efficient with a quote we were happy with. The team arrived on time, worked hard, everything done very neatly. Completed in one day and all the old parts taken away. Would recommend to anyone.
PHP are always reliable, knowledgeable and helpful. Matt, who serviced our boiler today, was very efficient and friendly. Thanks PHP.
I've used them for over 8 years and they've done a brilliant job every single time. Very professional, trustworthy and great at communication — they're my go-to whenever I have a problem.
Fantastic service from Jared and his team. I had a tricky issue that wasn't easy to locate, and they tried multiple options, wouldn't give up, and got it all sorted. They kept me fully updated on next steps and timing. Highly recommended.
Excellent service again following a leak in our bathroom. Easy to get hold of, great communication, they came when they said they would, fixed the problem really efficiently, and were clean, tidy and nice. Can’t recommend them highly enough.
Matt, you deserve a medal for your customer service. And many thanks to Tony for the brilliant job replacing our leaking kitchen tap. This is the second time we’ve used PHP and they are brilliant!
Plain sailing from start to finish. Clear, prompt communication about the electrical and plumbing job I requested. Matt arrived on time, professional, friendly and efficient, and completed the job without issue. Would definitely use again and recommend.
