That covers combi, system and heat-only boilers in houses and flats, rented properties on a landlord's books, and non-domestic boilers on commercial premises under our commercial Gas Safe registration. A repair visit starts with diagnosis rather than guesswork: fault codes read, gas pressure and gas rate checked, flue integrity and combustion tested, and the failed component identified before anything is quoted. Where a repair is not the economic choice we will say so plainly, give you the replacement price in writing, and leave the decision with you. Installation work is priced fixed. The quote covers the boiler, the flue route, the gas supply, controls, system cleaning and the commissioning paperwork, so the number you agree is the number you pay. As a Vaillant approved installer we can register the manufacturer guarantee on new plant alongside our own 12-month workmanship guarantee. Annual servicing is the part most people skip and later pay for. A service keeps the manufacturer guarantee valid, catches sealed-unit and combustion faults while they are still small, and gives landlords the record they need at inspection time. ### Homeowners No heating, no hot water, a boiler that keeps locking out, or an old unit that is costing more in call-outs than a replacement would cost to fit. ### Landlords & letting agents Boiler servicing scheduled alongside gas safety certificates across one property or a portfolio, with paperwork issued on completion. ### Commercial sites Non-domestic boilers, plant rooms and larger output appliances covered under our ACS Commercial qualification, with RAMS issued where required. Left alone, it gets worse ## What happens if a boiler fault is left alone A boiler rarely fails without warning. Noise, pressure loss, lukewarm water and repeated resets are the early stage, and every one of them gets more expensive the longer it runs. ### A cheap part becomes a new boiler A leaking seal or failing pump that could have been changed on one visit can wet and seize the main components, turning a single-part repair into a full replacement. ### Combustion faults are a safety issue Blocked flues, poor combustion and unsafe appliances put carbon monoxide into the property. This is the part of boiler work that is not worth delaying or leaving to an unregistered fitter. ### Pressure loss damages the system A system that keeps losing pressure is losing water somewhere. Introducing fresh water repeatedly brings in oxygen, which corrodes radiators and blocks heat exchangers with sludge. ### 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 end up paying for. ### 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 - Topping up pressure every week instead of finding the leak - Repeatedly resetting a boiler that is locking out for a reason - Using an unregistered fitter on gas work to save on the first invoice - Fitting a new boiler onto an old, sludged system without cleaning it - Replacing a boiler on size alone rather than on the property's heat demand and hot water use Our process ## How the job runs fromfirst call to guarantee Step 101 ### Inspection We take the detail on the phone, appliance, symptoms, property, urgency, then check the boiler, controls, gas supply and system pressure on site. Step 202 ### Diagnosis Fault codes, gas rate, working pressures and combustion readings are taken so the actual failed component is identified rather than guessed at. Step 303 ### Fixed price in writing You get a free fixed-price quote covering parts and labour. Basic quotes are usually with you within 48 hours; larger jobs depend on scope. Step 404 ### Repair or installation The work is carried out by Gas Safe registered engineers. On a replacement that includes flue, gas supply, controls, system cleaning and safe removal of the old unit. Step 505 ### Testing and verification Gas tightness test, gas rate, combustion analysis and full functional check of heating and hot water before we leave. Step 606 ### Completion and guarantee Paperwork issued, new plant registered for its manufacturer guarantee, and our 12-month workmanship guarantee applied. What you get ## The difference it makesonce the work is done ### Heat back on quickly The phone is answered around the clock, so a breakdown gets a real conversation with an engineer rather than a message left with an answering service. ### Safety confirmed, not assumed Combustion analysis, tightness testing and flue checks on every boiler visit, under Gas Safe registration 981690. ### Longer boiler life System cleaning, correct pressures and annual servicing keep heat exchangers and pumps out of the failure cycle. ### Lower running cost A correctly sized, correctly commissioned boiler with working controls burns less gas than an oversized unit short-cycling on old settings. ### Prices that do not move Quotes are fixed and free. No call-out sales pressure and no numbers changing once the covers are off. ### One point of contact You deal with the engineers doing the work, owner-led by Ryan Conniff with a team of four. In detail ## Boiler work in detail Boiler jobs vary far more than the phrase suggests. Below is what we actually work on, the methods we use, and the differences that change how a job is priced. ### Boiler types we install and repair Combi boilers, which heat water on demand and suit properties with one main bathroom; system boilers with an unvented or vented cylinder, which hold hot water for larger households and multiple bathrooms; and heat-only (regular) boilers on traditional vented systems with a feed and expansion tank. We also work on non-domestic boilers on commercial premises, where output, flueing and ventilation requirements differ from domestic work. As a Vaillant approved installer we fit Vaillant as our standard recommendation, and we service and repair the other common domestic brands you are likely to already have installed. ### Common faults and what they involve Ignition and lockout faults, failed diverter valves that give heating but no hot water, faulty pumps, seized three-port and two-port valves, blocked plate heat exchangers on hard-water systems, failed expansion vessels behind constant pressure loss, faulty PCBs, leaking pump and pipework seals, frozen condensate pipes in cold weather, and controls or thermostats that are calling incorrectly. Some of these are a same-visit fix. Others depend on part availability, in which case we say so on the visit rather than leaving you guessing. ### Replacement work: what a proper install includes Correct sizing against the property's heat loss and hot water demand rather than replacing like for like out of habit. Gas supply checked and upgraded where the pipe run cannot carry the appliance's gas rate. Flue routed and terminated to the current standards. Condensate run with fall and frost protection. System cleaned, power flush or chemical clean depending on condition, and a system filter fitted to keep debris out of the new heat exchanger. Commissioning is where guarantees are won or lost: gas rate set, combustion checked with an analyser, controls configured, and the benchmark and manufacturer registration completed. ### Servicing and hard water in Warwickshire An annual service covers combustion readings, gas rate, seals, the burner and heat exchanger condition, condensate, expansion vessel charge, safety devices and system pressure. 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. ### Residential and landlord work Domestic work is priced per job, usually completed in one visit for repairs and one to two days for a full replacement, with the property left clean and the paperwork handed over on the day. ### Commercial and industrial work Commercial boiler work runs under our ACS Commercial qualification with RAMS issued, planned access times, and account terms available. Testing, purging and pipework sizing follow the non-domestic standards. Where we cover ## Boiler installation, repair & servicing acrossWarwickshire and the Midlands We are based in Leamington Spa.
