Biasi Boilers
Biasi Boilers
Biasi boiler installation, servicing and repairs in Barnet and across North London by Gas Safe registered engineers. We work on the full current Biasi range and most older models — with a fixed written price before any work starts.
Biasi Boilers in North London, done properly the first time
Biasi boilers are compact and competitively priced, and we see plenty of them in the purpose-built flats around Finchley and Enfield. Parts are obtainable through specialist merchants rather than every local counter, so we check availability before quoting a repair.
Whether you need a straight Biasi swap, a move from a regular boiler and cylinder to a Biasi 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 Biasi boilers the faults we are called to most are ER01 — ignition failure; ER02 — overheat; ER03 — fan fault; Low pressure from vessel loss. 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.
Flats and small properties, especially like-for-like Biasi replacements. If you are weighing Biasi 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 Biasi boilers in Barnet?
Yes. Our Gas Safe registered engineers install, service and repair Biasi 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 Biasi models do you work on?
We work across the current Biasi range — including Advance Plus, Inovia, Riva Plus, Garda — and we still service and repair older models where parts remain available.
How much does a Biasi 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We do not publish prices for boiler work, because the honest figure depends on the model, the state of your existing system, flue and condensate routes, gas pipe sizing and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 Biasi boiler?
Warranty length depends on the specific Biasi 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 Biasi boiler that has locked out?
Usually, yes. The faults we see most often on Biasi are ER01 — ignition failure; ER02 — overheat; ER03 — fan fault. We diagnose first, tell you what the part and labour will be, and only then carry out the repair.
