London is not one heating market — it is dozens of them stacked on top of each other. A Victorian terrace in Lewisham, a 1930s semi in Eltham, a Georgian townhouse in Greenwich and a 2015 apartment in Kidbrooke each fail in completely different ways, and each needs a different specification. Pricing all four from the same template is how homeowners end up with an oversized boiler, a lukewarm top-floor bedroom or a warranty that quietly lapses. Our working base is South East London, and that is deliberate. Staying inside a tight radius is what makes same-day attendance realistic rather than a call-centre promise. Greenwich, Lewisham, Bexley and Bromley are covered daily; work further across the capital is taken on where the diary genuinely allows it, and we will say so honestly on the phone rather than book something we cannot reach. London properties bring constraints that engineers outside the capital rarely deal with. Flue terminations near boundary lines and light wells, freeholder and managing-agent consent in converted flats, conservation-area restrictions on external pipework, limited loft space in top-floor maisonettes and gas runs from a shared meter cupboard three floors down. Each of these has to be checked before a quote, not discovered mid-installation. Gas supply is the single most common thing that goes unchecked. A great many London homes still run their original 15mm or 22mm gas run from the meter. Fit a 30kW+ combi on the end of it and the boiler will lock out under full load, usually on the coldest night of the year. We carry out a working-pressure and gas-rate test before quoting, and price any required uprate up front. We also work with London landlords, letting agents and small portfolio owners on annual gas safety rounds. Landlord Gas Safety Records are issued digitally the same day, and any remedial work is quoted separately in writing so you can compare it against another price rather than being cornered on the doorstep. Everything is carried out by Ian personally under Gas Safe registration 952303, with ACS qualifications, G3 certification for unvented hot water and NVQ Level 3. One engineer, one point of contact, one person accountable if anything needs revisiting inside the twelve-month workmanship guarantee.

Local property issues ## What we seemost often in London. Across London the same faults recur, but for reasons that differ street by street. These are the ones we are called to most often. ### Combi boilers fitted on undersized gas supplies One of the most widespread faults in London housing. The boiler runs fine in autumn and then locks out repeatedly in December because the gas run cannot deliver its rated input. The correct fix is a gas-rate and working-pressure test, then an uprated supply — not another replacement PCB. ### Pressure loss in converted and purpose-built flats Sealed systems in flats that need topping up every few weeks almost always point to a failed expansion vessel, a passing pressure relief valve discharging outside, or a small leak in a buried circuit. We test the vessel charge properly rather than repressurising and leaving. ### Back boilers and floor-standing units still in service Thousands of London homes still run a back boiler behind the lounge fire or an ageing floor-standing unit in the kitchen. Parts are scarce and efficiency is poor. Relocation needs a compliant flue route, a correctly made-good builder's opening and a full system flush before the new boiler is commissioned. ### Magnetite in Victorian and inter-war small-bore pipework Cold radiator bottoms, kettling and short-cycling are symptoms of sludge, not of a failed boiler. A chemical powerflush plus a correctly fitted magnetic filter restores output and protects the warranty on any new installation. ### Extensions and loft conversions on an unchanged system London homes gain rooms constantly and the heating system rarely gets revisited. The result is a boiler at capacity and radiators that never reach temperature. A room-by-room heat loss calculation and a rebalanced, sometimes zoned, circuit is the real answer. ### Unvented cylinders left uncertified Unvented hot water requires G3 competence to install, service and certify. We regularly find expansion vessels flat, tundishes discharging and no service history at all — which is both a safety issue and a warranty problem.

Which parts of London do you cover?Core daily coverage is South East London — Greenwich, Lewisham, Bexley and Bromley, including Eltham, Blackheath, Greenwich, Woolwich, Lee, Kidbrooke, Sidcup, Welling and Bexleyheath. Work further across the capital is considered depending on the job and the diary; call 07460 067161 and we will give you a straight answer. Can you attend a London boiler breakdown the same day?Inside the core South East London area, urgent no-heat and no-hot-water calls are commonly attended same-day or next-day, subject to availability. Because Ian attends personally rather than dispatching a team, we tell you honestly when we can be there instead of quoting a slot we cannot keep. Do you work in flats where the freeholder or managing agent is involved?Yes. Flue routing, external pipework and boiler relocation in converted or purpose-built flats often need consent, and we will tell you at survey stage what approval is likely to be required so it can be arranged before the installation date. Do you carry out Landlord CP12 certificates across London?Yes. Every gas appliance is tested, the installation pipework checked and the Landlord Gas Safety Record issued digitally the same day under Gas Safe 952303. Any remedial work is quoted separately in writing. Is there a parking charge for London jobs?If there is no free parking near the property, we will ask you to cover a permit or meter. It is passed on at cost with no markup, and most jobs in areas with free parking will not incur it at all. What does a boiler installation typically cost in London?Boiler installations in London 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.

Do you offer emergency call-outs in London?Yes — out-of-hours cover is available in London, 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 London?Always. For installations and larger jobs we assess on site, then send a written fixed-price estimate.

On new boiler installations, manufacturer warranties are typically 7–10 years, subject to annual servicing. Are you Gas Safe registered?Yes — Gas Safe Register number 952303.
