Offerton is a short hop from our Hazel Grove workshop, one of our fastest response areas, and a substantial chunk of our maintenance-contract customer base. It's a predominantly post-war and 1960s–70s residential area with a good mix of semis, short terraces and small detacheds. The housing stock is generally on its second or third boiler generation and the current wave of replacements tends to be modern condensing combis. Straightforward work, done in volume, done properly. Response time Offerton is a five-minute drive from our workshop. Same-day breakdown attendance in working hours is routine, and we regularly fit in an early-morning look before scheduled bookings on cold days.

You speak to John, and John does the work, the same person for four decades of Stockport borough heating. 5 min Typical drive from HQ 500+ Ongoing maintenance customers SK2 Neighbouring postcode 12 mo Workmanship guarantee Common Offerton problems ## What we see most, right here. Every area has patterns: property age, climate exposure, water hardness and installation history all shape which faults keep coming up. Here's what's most common in Offerton, and how we handle it. ### Undersized combi replacements from generalist installers Very common in Offerton, a 24 kW combi where the property needs 28–32 kW for real comfort. ### External condensate freeze Same regional issue, same permanent fix. ### Aged pipework on 1960s stock Small joint weeps rather than dramatic leaks. Requires patience, not just repressurising. ### Ignored annual servicing Boilers running rich for years. We spot it on the first proper service and set it right. ### Sludged systems Older radiators, no flush history, quietly killing pumps. Our process ## A clear five-step system, the same in every home. Whether you're on a main road or a tucked-away close, the process is identical. No guessing, no meter-running. 1. 01 ### Callback Ring John or request a callback. You'll speak to the engineer directly, no call centre. 2. 02 ### Diagnose On-site inspection, combustion analysis and root-cause diagnosis. No swap-and-hope. 3. 03 ### Explain Plain-English rundown of the fault and the options. Fixed price where possible. 4. 04 ### Repair Most parts on the van. Job done neatly, first visit where possible. 5. 05 ### Guarantee 12-month workmanship guarantee and a written record for your files. FAQs ## Offerton questions we hear every week. If your question isn't answered here, ring John directly on 07442 536165. ### Do you serve Offerton? ### How fast can you reach Offerton for an emergency? ### How much does a boiler service cost in Offerton? ### Are you Gas Safe registered? ### Do you offer emergency call-outs in Offerton? ### What guarantee do you offer on work in Offerton? ### Can you service any make of boiler in Offerton? ### Do you take on landlord CP12 gas safety checks in Offerton? ### How do I book you for a visit in Offerton?

Everything on this page reflects real, ongoing work on this postcode, not a template. If you have a question that isn't answered, ring John. **One engineer, one van, one number.** Every visit in Offerton is carried out personally by John Swainson. There's no sub-contracting, no rotating trainee, and no call-centre buffer between you and the person doing the job. That's the model the business has run on since 1986, and it's why our maintenance-contract list keeps growing rather than churning. **Parts on the van.** The van carries the components that fail most often on the boilers we service in Offerton, diverter valves, PCBs, pumps, fans, expansion vessels, PRVs, gaskets, thermistors and the common Worcester, Vaillant and Ideal service kits. That's why most breakdowns finish on the first visit. **Honest pricing.** Basic service from £98 inc. VAT, full service £155 + parts inc. VAT, call-out and diagnostic £98 inc. VAT, landlord CP12 from £110 inc. VAT, maintenance contract £208 / year inc. VAT. Same in Offerton as at our Stockport base, no travel surcharge, no postcode loading, no call-out inflation. **Written record every time.** After every service, repair or CP12 you'll get a written record, the same document a landlord, buyer, insurer or manufacturer warranty administrator will ask for. It goes on the file, and stays on the file. **Nearby coverage.** Alongside Offerton, we cover Hazel Grove, Davenport, Heaviley, Stockport, Woodley and the wider Stockport borough, the same standard of work across the whole patch. ![Swainson Gas Services](/__l5e/assets-v1/2f3afd23-ed83-4d5d-a90b-6d75c9544dc3/swainson-logo.png) Swainson Gas Services Family run · Est. 1986 Stockport's trusted boiler repair, servicing and gas safety specialists.
