Our scope covers natural gas appliances — boilers, hobs, ovens, fires, water heaters — in domestic properties. Every engineer is on the Gas Safe register, with the appliance-specific competencies relevant to the work. ### Who it's for Anyone with a gas appliance: homeowners, landlords, letting agents and property managers. Particularly important for landlords, who are legally required to commission an annual Gas Safety Certificate (CP12) on every let property in their portfolio. ### When it's needed Annually as a minimum — for every gas appliance, every year. Outside that: any time you smell gas (call the National Gas Emergency Service first on 0800 111 999), if a pilot light keeps going out, if a flame burns yellow or orange instead of blue, if you notice soot marks around an appliance, or if you're buying or selling a property and want a safety check. ### Why a professional matters Beyond legal compliance, gas faults cause two of the most serious risks in any property: explosion from undetected leaks, and carbon monoxide poisoning from incomplete combustion. CO is colourless, odourless, and kills around 60 people in the UK every year, with thousands more hospitalised. Annual servicing by a Gas Safe engineer is the single most important safety check you can run on a home. The Cost of Waiting ## Gas is unforgiving when it goes wrong. The realities of what we see when an appliance hasn't been serviced for years: - Sooted combustion chambers producing measurable carbon monoxide in living spaces — invisible until a CO alarm sounds (if there is one). - Cracked heat exchangers leaking water into electronics, leading to boiler failure on a freezing weekend. - Corroded flue joints venting combustion products inside the loft or upstairs rooms. - Old isolation valves seized open, meaning a small leak can't be safely contained for repair. The Consequence An annual service costs £80+VAT. The alternative is a £3,000 forced boiler replacement, a £15,000 fire-damage insurance claim, or — in the worst case — a hospital trip. The maths is not subtle. [Get a Fixed-Price Quote](/contact) [07815 022377](tel:+447815022377) Our Process ## Five steps. No surprises. 01 ### Booking & Triage Quick call to understand the appliance, age, brand and symptoms. Booked in for the next slot that suits you. 02 ### Safety Inspection Visual inspection, controls test, flue check, ventilation assessment, gas tightness test on the supply. 03 ### Combustion Analysis Flue gas analyser measures CO/CO₂ ratio and combustion efficiency — the only objective way to verify safe operation. 04 ### Diagnosis or Service Either a full annual service to manufacturer schedule, or repair with a written fixed-price quote before parts are fitted. 05 ### Certify & Document Gas Safe documentation, service record, and (if relevant) CP12 certificate — emailed within 24 hours. Why Choose On-Tap ## The benefits, plainly stated. ### Legal compliance Landlord obligations met, mortgage and insurance paperwork in order, every job on the Gas Safe register. ### Warranty protection Manufacturer warranties stay intact — most boiler warranties are voided without an annual service by a registered engineer. ### Verified efficiency Flue gas analysis measures actual combustion performance — no guesswork. ### Fast scheduling Most gas work booked within 3-5 working days. Same-day emergency cover during opening hours. ### Plain English We explain what we found, what it means, and what (if anything) needs doing — without sales pressure. ### Transparent pricing £80+VAT for a full annual service, fixed-price quotes for repairs and installs. In Depth ## Gas work explained — what's involved and what to expect. Gas Safe scope covers a lot. Here's a fuller picture of what a competent engineer actually does on site. ### Annual gas safety servicing A proper service is much more than a visual check. To manufacturer schedule, it includes: removal and inspection of the burner, heat exchanger and combustion chamber; check of the flue (entire length, joints, terminations); ignition and flame test; combustion analysis (CO/CO₂ ratio measured at the flue); pressure and gas tightness test; condensate trap clean (on condensing boilers); controls and safety device test (overheat thermostats, pressure relief valves); and a written report. ### Leak detection and rectification If you smell gas, leave the property and call the Emergency Service Provider on 0800 111 999 — they will make the supply safe, then leave the repair to a Gas Safe engineer. We use electronic gas detectors and (where appropriate) leak detection fluid to trace the source. Most leaks are at isolation valves, flexible appliance connectors or compression joints — usually a 1-2 hour repair with a tightness test on completion. ### Appliance installation & relocation Installing or moving a gas hob, cooker, fire or boiler requires correct pipe sizing (often a 22mm run for a modern combi), proper isolation, flue planning, ventilation calculations (for any non-room-sealed appliance), and certification. We size, install and commission to manufacturer specifications, with the gas tightness and combustion paperwork to back it up. ### Landlord gas work Landlords must hold a current CP12 (Gas Safety Certificate) for every let property, renewed annually and inspected within 12 months of any new tenancy. We carry out CP12 work for landlords and agents, including portfolio-scale contracts. FAQs ## Questions, answered. Anything else? Call [07815 022377](tel:+447815022377).
