A new PRV that keeps weeping is not a faulty PRV — it's a knackered expansion vessel pushing pressure into it. We diagnose the system, not just the part, and we put the diagnosis in writing before any spanner comes out. ### What it is Gas boiler diagnosis and repair on every common UK brand — Ideal, Baxi, Worcester Bosch, Vaillant, Glow-worm, Potterton, Main, Alpha and Viessmann. PCBs, fans, gas valves, diverter valves, expansion vessels, PRVs, ignition leads, thermistors, auto air vents and pumps. ### Who it's for Homeowners and landlords across Scunthorpe, Brigg, Messingham, Scotter, Kirton Lindsey, Barton-upon-Humber, Hull, Grimsby and Doncaster whose boiler is locking out, leaking, losing pressure, or simply refusing to fire on a cold morning. ### When it's needed Error codes on the display, no hot water, no heating, low pressure that needs topping up weekly, banging or kettling noises, water dripping from the bottom of the case, a yellow pilot flame, or a system that fires up then trips out within minutes. ### Why a professional matters Gas work is a legal requirement to be carried out by a Gas Safe registered engineer. A wrong diagnosis on a boiler doesn't just waste a part — it can void the manufacturer warranty, push carbon monoxide into the house, and turn a £180 repair into a £3,000 replacement. What goes wrong ## Boiler faults we see most weeks across North Lincs Nine times out of ten, the boiler isn't the problem — the system around it is. Here's what's actually behind the most common call-outs: ### Pressure dropping, won't hold Almost always a failed expansion vessel or a slow leak on a rad valve or towel rail. Topping it up weekly just corrodes the system from the inside. ### Error code F1 / F22 / E119 Low-pressure lockout codes across Vaillant, Worcester and Ideal. The code tells you the symptom; we find the cause — internal weep, vessel collapse, or external leak. ### Locks out on ignition (F28, EA, L2) Spark electrode, ignition lead, gas valve, flame sense — or a partially blocked condensate trap. Diagnosed properly with a manometer and combustion analyser. ### Hot taps lukewarm only Classic stuck diverter valve. Common on Worcester Greenstars and Ideal Logics — cartridge swap rather than a full valve in most cases. ### Kettling, banging, gurgling Limescale on the heat exchanger or magnetite sludge in the system. A chemical or power flush plus a system filter typically resolves it without replacing the boiler. ### PRV dripping outside the wall Sign of internal over-pressure — usually the expansion vessel has lost its charge. Re-charge first; if it fails again, replace the vessel. ### Condensate frozen in a cold snap Externally routed condensate pipework freezes overnight in January and locks the boiler out. We thaw, re-route internally where possible, and lag what we can't. Our process ## How a boiler repair actually runs with us Same disciplined process whether it's a Worcester in Scunthorpe or a Baxi in Hull. - 01 ### Phone diagnosis We'll ask for the make, model, error code and what you've already tried — sometimes we can solve it on the call. If not, we book a diagnostic visit. - 02 ### On-site diagnosis Combustion analyser, manometer and meter checks — we prove the fault rather than guess at it. Diagnostic charged at £60+VAT first hour, £50+VAT per hour after, agreed in writing. - 03 ### Written repair quote Fixed price for the parts and labour to fix it properly. You decide before we order anything. No work happens until you say yes. - 04 ### Repair carried out Common consumables fitted from the van same-visit. Specific PCBs, gas valves or fans ordered next-day from the local trade counter. - 05 ### Test & sign-off Gas-rate set, flue gas analysed, system pressure reset, controls demonstrated. Benchmark and invoice issued on the day. - 06 ### 12-month guarantee Workmanship guaranteed in writing for 12 months. Same fault returns inside that window, the return visit is free.
