A box-ticking 'visual check' is not a service: it doesn't catch the silent faults that turn into a January breakdown, and it won't satisfy the manufacturer if you ever need to claim on the warranty. ### What it is A full annual gas boiler service to manufacturer specification — burner and heat exchanger inspected, seals checked, condensate trap cleaned, gas-rate measured, full combustion analysis with a calibrated flue gas analyser, controls tested, and a benchmark / service record signed and filed. ### Who it's for Homeowners and landlords across Scunthorpe, Brigg, Messingham, Scotter, Kirton Lindsey, Barton-upon-Humber, Hull, Grimsby and Doncaster who want to keep their warranty valid, catch faults early, and run the system efficiently through winter. ### When it's needed Once a year, every year — typically in the same calendar month each year. Manufacturer warranties on Ideal, Baxi and Worcester require an annual service to remain valid. Landlords also need an annual gas safety check (CP12) on top, often booked together. ### Why a professional matters An unserviced boiler runs less efficiently, fails more often, and silently invalidates the manufacturer warranty. The price of one missed service is typically smaller than the price of one PCB replacement on a 6-year-old boiler that the manufacturer would have covered. What goes wrong ## What we find on first services for new customers When someone rings because their last engineer 'wasn't bothering' anymore, here's what we usually find: ### Condensate trap full of sludge Never cleared in years of 'services'. Eventually blocks, water backs up, boiler locks out — almost always on a Friday night. ### Combustion never analysed No flue gas analyser used means no proof the gas-air ratio is correct. A boiler running rich wastes gas and produces CO. ### Benchmark book never filled in If the benchmark or service record is empty, the manufacturer will reject any warranty claim — even on a 2-year-old boiler. ### System filter never cleaned MagnaClean and ADEY filters are emptied every service. If the filter cup is full of black sludge, the heat exchanger is being cooked. ### Inhibitor level not tested Inhibitor degrades over time. Without an annual test, corrosion accelerates and the system fills with magnetite within 3–4 years. ### Loose flue fittings Vibration loosens flue joints over time. A flue gas test catches a leak before it becomes a CO risk. Our process ## What's actually included in our boiler service The full manufacturer schedule, every visit. No shortcuts. - 01 ### Pre-service checks Visual inspection of installation, flue termination, ventilation, gas tightness test on the supply pipework. - 02 ### Case off & inspect Casing removed, burner, heat exchanger, fan and seals inspected. Any signs of overheat, corrosion or wear flagged in writing. - 03 ### Combustion analysis Calibrated Kane or Anton flue gas analyser used to measure CO, CO₂ and ratio — proves the boiler is burning cleanly within manufacturer parameters. - 04 ### Gas rate measurement Gas-rate measured at the meter and cross-checked against manufacturer spec. Adjusted where needed. - 05 ### Condensate & system checks Condensate trap emptied and cleaned, system pressure verified, expansion vessel charge checked, system filter emptied if fitted. - 06 ### Sign-off & benchmark Service record / benchmark book completed, gas safety record issued (CP12 if landlord), invoice and certificates handed over on the day. Benefits ## Why an annual service pays for itself ### Warranty stays valid Ideal, Baxi and Worcester all require documented annual servicing to honour the 10-year parts & labour warranty. ### Cheaper running costs A properly tuned boiler burns gas more efficiently. The annual fuel saving often pays for the service on its own. ### Faults caught early A failing fan, a cracked seal or a tired expansion vessel found in October costs less than the emergency call-out in January. ### Carbon monoxide peace of mind A flue gas test proves the boiler is burning safely — not just running. ### Properly documented Benchmark book filled, certificate issued — everything a solicitor, insurer or letting agent will ever ask for. ### Same engineer year on year Azim knows the system, knows what was flagged last year, and tracks the boiler's condition over time.

Ring Azim directly on 07576 593045. ### How much is a boiler service? Standard combi boiler service is a fixed price agreed in writing before we book the visit. Landlord CP12 + service bundles and multi-property contracts are priced on request. ### How long does a service take? A standard combi service takes around 45–60 minutes on-site. Older heat-only or system boilers with separate cylinders can take a little longer. ### Will it keep my warranty valid? Yes — we service strictly to manufacturer spec and complete the benchmark / service record, which is exactly what Ideal, Baxi and Worcester require to honour the 10-year warranty. ### Do you service boilers you didn't install? Absolutely — we service every brand, regardless of who installed it. Anything non-compliant we find gets flagged in writing without being used as a sales pitch. ### Can you do the gas safety certificate at the same time? Yes. Landlord CP12 + annual boiler service is the most common booking for our rental customers in Scunthorpe and Doncaster. Both certificates issued in one visit. ### How often does a boiler need servicing? Every 12 months. Manufacturer warranties on Ideal, Baxi and Worcester require it, and an unserviced boiler runs less efficiently and fails sooner. ### What if you find a fault during the service? We'll flag it in writing with a fixed-price repair quote. You decide whether to go ahead. No work happens beyond the agreed service without your say-so. ### Do you cover oil-fired boilers? No — we cover gas appliances only. We don't carry out oil-fired (OFTEC) work.
