A service is a set of checks and readings, not a wipe over the casing. Combustion is analysed, gas rate measured, seals, burner and heat exchanger condition inspected, condensate checked, expansion vessel charge tested, safety devices proved and system pressure set. Servicing is the part most people skip and later pay for. It keeps the manufacturer guarantee valid, catches sealed-unit and combustion faults early, and gives landlords the record they need at inspection time. Anything found is reported with the honest options and a fixed price, so you are never presented with work you did not agree to. ### Homeowners An annual service to keep the appliance safe, efficient and inside its manufacturer guarantee terms. ### Landlords and letting agents Servicing scheduled alongside gas safety certificates across one property or a portfolio, with paperwork issued on completion. ### Commercial sites Non-domestic appliances and plant covered under our ACS Commercial qualification, on a planned basis with RAMS where required. Left alone, it gets worse ## What skipping the service actually costs Nothing appears to happen the year you skip a service. The cost shows up in gas use, in the failure that was preventable, and in the guarantee claim that gets declined. ### The guarantee lapses Miss the annual service and the manufacturer guarantee on a new boiler can be refused, so the one repair you most want covered is the one you pay for. ### Small faults become breakdowns Seals, expansion vessels and combustion drift are cheap to correct at a service and expensive once they take out the appliance in midwinter. ### Unsafe combustion goes unnoticed Poor combustion and flue faults are not visible from the room. Analysis at a service is how they get found before they become a carbon monoxide risk. ### Landlords lose compliance An out-of-date gas safety record on a let property is a legal exposure, not an admin oversight, and it is the landlord who carries it. ### Common mistakes we are called out to correct - Skipping the service in the year a boiler seems fine - Accepting a visual check with no combustion readings as a service - Letting the service date drift past the guarantee anniversary - Servicing the boiler while ignoring dirty system water - Booking landlord certificates and servicing as two separate visits Our process ## How the job runs fromfirst call to guarantee Step 101 ### Booking We take the appliance, property and access details, and can schedule servicing alongside a gas safety record where one is due. Step 202 ### Safety checks Gas tightness testing, ventilation, flue integrity and appliance clearances checked before anything else. Step 303 ### Inspection Casing off: burner, heat exchanger, seals, condensate, expansion vessel charge and safety devices inspected and tested. Step 404 ### Combustion and gas rate Combustion analysed with a calibrated analyser and gas rate measured against the manufacturer's figures. Step 505 ### Adjust and report Settings corrected and system pressure set. Anything found is reported with the options and a fixed price, never carried out unagreed. Step 606 ### Paperwork Service record issued, and the landlord gas safety record where that was part of the visit. What you get ## The difference it makesonce the work is done ### Guarantee kept valid The annual service and its record are what keep a manufacturer guarantee enforceable when you need it. ### Fewer winter breakdowns Faults found at a service are corrected on a scheduled visit rather than an emergency call-out. ### Safety confirmed, not assumed Combustion analysis, tightness testing and flue checks under Gas Safe registration 981690. ### Lower gas use A boiler running at the correct gas rate with clean combustion and set controls burns less than one drifting on old settings. ### Compliance handled Landlord servicing and gas safety records scheduled together, with paperwork issued on completion. ### No pressure selling Findings are reported with honest options and fixed prices. You decide what goes ahead. In detail ## Boiler servicing in detail What separates a real service from a visual check is the readings taken and recorded. Below is what we test and why it matters. ### Combustion and gas rate Combustion is analysed with a calibrated analyser and compared against the manufacturer's figures, and gas rate is measured at the meter. Together these show whether the appliance is burning correctly or drifting out of specification. Readings are recorded, which is what a manufacturer will ask for if a guarantee claim is made. ### Safety devices and flueing Gas tightness testing, ventilation and flue integrity, appliance clearances, and the safety devices that shut the boiler down in a fault condition, all proved rather than assumed. Flue faults and poor combustion are the part of a service that is genuinely about safety rather than efficiency. ### Hard water and combis in Warwickshire On combis in hard-water areas we pay particular attention to plate heat exchanger scaling, which shows up as hot water that runs warm and then cold. Where scaling is the recurring cause we will tell you what actually solves it rather than repeating the same descale visit every year. ### Landlord servicing and portfolios Servicing can be scheduled alongside CP12 gas safety records across a single property or a portfolio, with access arranged around tenants and paperwork issued on completion. Planned maintenance agreements are available where you would rather the dates were managed for you. ### Residential and landlord work A domestic service is normally a single short visit per appliance, with the service record handed over on the day. ### Commercial and industrial work Commercial servicing runs under our ACS Commercial qualification with RAMS issued, planned access times and account terms available.
