Our Story
We started Aphex Heating with a simple frustration: too many homeowners in St Albans were being let down by rushed installs, surprise charges, and engineers who didn't take pride in their work. We wanted to do things differently — to treat every home as if it were our own, and to leave every job cleaner and better than we found it.
Over 15 years later, that ethos hasn't changed. We're still a St Albans-based team, still fitting the same premium brands we've trusted since the beginning, and still picking up the phone when our customers call. Our 5.0-star Google rating and 10/10 Checkatrade score reflect what we've always cared about most: doing the job properly and standing behind it.
The Aphex Standard — What Sets Us Apart
We're not a volume installer. We don't race through jobs to fit the next one in. The "Aphex Standard" is the set of non-negotiables we apply to every single installation:
Only Approved Brands, Installed Properly
We're approved installers for Worcester Bosch, Vaillant, and Navien — three of the most reliable boiler brands on the market. Because of our approved-installer status, we can offer manufacturer-backed warranties of up to 18 years. That's only possible when an installation meets the manufacturer's own quality benchmarks, verified at commissioning.
Free Power Flush on Every Installation
Every new boiler we fit includes a full professional power flush and magnetic filter installation at no extra charge. This removes magnetite sludge from your system, protects your new boiler from day one, and is one of the most important steps most installers skip to save time.
Meticulous Pipework. Tidy Finish. No Exceptions.
We use dust sheets, protect your floors and walls, and remove every piece of waste from the property when we're done. Our pipework is routed neatly and finished to a high standard — not because we have to, but because it's the difference between a good job and a great one.
Transparent, Fixed Pricing
You'll receive a fixed written quote before we begin. No callout surprises, no hidden VAT adjustments mid-job. What we quote is what you pay.
Heating Finance, FCA Regulated
For customers who prefer to spread the cost, we offer finance through Phoenix Financial Consultants (FCA authorised, FRN: 539195). Aphex Heating is an Introducer Appointed Representative (Financial Services Register No. 1017285). All finance is subject to status and credit checks.
