Potterton Boilers
Potterton Boilers
Potterton boiler installation, servicing and repairs in Barnet and across North London by Gas Safe registered engineers. We work on the full current Potterton range and most older models — with a fixed written price before any work starts.
Potterton Boilers in North London, done properly the first time
We still service a lot of Potterton boilers across Barnet and Enfield, including older Promax and Suprima units. Because Potterton now sits within the Baxi group, parts for current Assure models are readily available and legacy parts are often still obtainable.
Whether you need a straight Potterton swap, a move from a regular boiler and cylinder to a Potterton combi, or a diagnosis on a unit that keeps locking out, the work is carried out by our own Gas Safe engineers — never sub-contracted. We survey the property first, because the right answer in a three-storey Victorian terrace in New Barnet is rarely the right answer in a two-bed flat in Whetstone.
On Potterton boilers the faults we are called to most are E119 — low pressure; E125 — circulation fault; E133 — ignition lockout; Legacy Suprima PCB failures. Most are repairable in a single visit once diagnosed properly, and we will always tell you plainly when a repair is not worth the money against a replacement.
Like-for-like replacements in homes that already have Potterton pipework and controls. If you are weighing Potterton against another manufacturer, ask us — we install every major UK brand, so we have no reason to steer you anywhere except the boiler that suits your property, your hot water demand and your budget.

Your questions, answered
Do you install Potterton boilers in Barnet?
Yes. Our Gas Safe registered engineers install, service and repair Potterton boilers across Barnet (EN5, EN4 and N20) and the neighbouring N2, N3 and N12 postcodes, as well as Finchley, Muswell Hill, Hampstead, Highgate, Enfield and the rest of North London.
Which Potterton models do you work on?
We work across the current Potterton range — including Assure Combi, Assure System, Titanium, Promax (legacy) — and we still service and repair older models where parts remain available.
How much does a Potterton boiler cost to install?
We do not publish prices for boiler work, because the honest figure depends on the model, the state of your existing system, flue and condensate routes, gas pipe sizing and access. Send us a few details or call and we will give you a fixed written price for your property before anything is booked.
What warranty comes with a new Potterton boiler?
Warranty length depends on the specific Potterton model, the installation and registering the boiler with the manufacturer, so we confirm the exact terms in writing with your quote rather than quoting a headline figure. Annual servicing is normally a condition of keeping any manufacturer warranty valid. Our own workmanship guarantee sits on top of it.
Can you repair a Potterton boiler that has locked out?
Usually, yes. The faults we see most often on Potterton are E119 — low pressure; E125 — circulation fault; E133 — ignition lockout. We diagnose first, tell you what the part and labour will be, and only then carry out the repair.
