Mottingham has a very particular housing profile: large stretches of planned inter-war and post-war estate housing, built quickly to a standard specification, now sixty to ninety years old. That means we see the same handful of faults repeatedly — and can price and diagnose them without guesswork. A lot of Mottingham homes still run open-vented systems with a loft feed-and-expansion tank and a copper cylinder in the airing cupboard. Some are worth keeping and improving; others are far better converted. We give a straight answer on which, rather than defaulting to whatever is easiest to sell. Because the estate housing was built to consistent layouts, boiler siting and flue routing follow predictable patterns — but only if the property has not already been altered. Where previous owners moved kitchens or added extensions, an on-site assessment is essential before any quote. Ian carries out every Mottingham job personally, holds Gas Safe registration 952303, and issues the paperwork himself. Nothing is subcontracted, and no work starts until you have accepted a written estimate. Coverage Mottingham village, the Mottingham Estate, Court Farm Road, Sidcup Road and the residential roads running towards Grove Park and Chislehurst.

Local property issues ## What we seemost often in Mottingham. Mottingham's estate-built housing produces a recognisable and repeatable set of heating problems. ### Failing open-vented cylinders and loft tanks Original copper cylinders lose insulation performance, and loft feed tanks corrode or freeze. Symptoms are slow hot-water recovery, discoloured water and airlocks. Replacement — or conversion to a sealed system — is usually more economic than repeated patching. ### First-generation combis reaching end of life Many Mottingham homes had a combi fitted 15–20 years ago. Once the diverter valve, heat exchanger and PCB all start failing in the same season, further repair is money wasted. We give an honest repair-versus-replace assessment with parts prices in writing. ### Cold upstairs, hot downstairs Unbalanced circuits are endemic in estate housing where radiators have been added or swapped over the decades. Correct balancing, new TRVs and sometimes a repositioned pump resolve it without a new boiler. ### Corroded steel pipework in older runs Where original steel heating pipe survives, internal corrosion narrows the bore and feeds sludge into the boiler. Localised repipe plus a powerflush is the durable fix. ### Landlord compliance across converted properties Several Mottingham houses now operate as multi-occupancy lets. Every gas appliance needs an annual Landlord Gas Safety Record — we certify the whole property in one visit and flag remedials clearly.

Mottingham FAQ ## Answers beforeyou commit. Not covered here? Call Ian directly on 07460 067161. Is Mottingham inside your standard service area?Yes, fully. Mottingham sits between Eltham, Grove Park and Chislehurst, all of which we work in weekly, so there is no travel surcharge on booked work. Should I convert my Mottingham gravity system to a combi?Sometimes. In a one-bathroom home with good mains pressure, a combi is usually the better choice. In a larger house with two bathrooms, a system boiler with an unvented cylinder normally performs far better. We assess mains flow and pressure on site before recommending either. Do you charge for a repair diagnosis in Mottingham?Labour is charged at £90/hr Monday to Friday, 8am–5pm, and £150/hr out of hours. You are told the rate and likely time before we attend, and any parts are quoted before they are fitted. What does a boiler installation typically cost in Mottingham?Boiler installations in Mottingham are quoted in writing after an on-site assessment — we don't give phone-quote figures because the flue route, gas-supply size, controls, filter and cylinder work all affect price. Labour is charged at £90/hr Mon–Fri 8am–5pm on hourly work and £150/hr out-of-hours; installations are usually a fixed price against the written estimate. No VAT is currently charged. Do you offer emergency call-outs in Mottingham?Yes — out-of-hours cover is available in Mottingham, charged at £150/hr. For genuine emergencies (gas leaks, no heat with vulnerable occupants) call 07460 067161 directly and Ian will advise on response time. Do you provide a written estimate before starting work in Mottingham?Always. For installations and larger jobs we assess on site, then send a written fixed-price estimate.
