The Kent border towns are a distinct heating market from inner London. The housing is overwhelmingly inter-war and post-war suburban — larger floor plans, more bathrooms, more extensions and far more properties still running open-vented systems with a loft tank and an airing-cupboard cylinder. What suits a two-bed London flat is often exactly the wrong specification here. Because these homes are bigger, combi conversion is not automatically the right move. A four-bedroom Sidcup or Bexleyheath house with two bathrooms will usually give better simultaneous hot water from a system boiler and a properly sized unvented cylinder. Ian is G3 qualified to install, commission and certify unvented hot water, so the advice is not shaped by what he happens to be able to fit. Extension work is the defining feature of these streets. Rear kitchens, side returns, loft conversions and garage conversions have been added across the area for decades, almost always without the heating system being reassessed. The predictable outcome is a boiler running flat out, a hallway that overheats and a new room that never warms up. The fix is a room-by-room heat loss calculation and a rebalanced circuit, sometimes with a second zone. Older gravity-fed systems remain common on the Kent border, and not all of them should be ripped out. Where the cylinder and pipework are sound, upgrading controls, adding a proper pump and fitting a modern system boiler can be the better value decision. Where the pipework is heavily sludged and the cylinder is failing, it is not. We give a straight recommendation either way. Landlords across Sidcup, Welling and Bexleyheath use us for annual gas safety rounds. Certificates are issued digitally the same day under Gas Safe 952303, tenants can be contacted directly for access with your authorisation, and remedial work is quoted in writing rather than pushed on the day. Every job is Ian's own work — no subcontractors, no rotating engineers, and the same person on the phone at the twelve-month mark as on the first visit.

Property types Mock-Tudor and bay-fronted 1930s semis, inter-war detached homes with later extensions, post-war estate housing, bungalows and larger period properties on the Chislehurst side.

Local property issues ## What we seemost often in Kent. The faults we are called to across the Kent border towns follow the housing stock closely — larger suburban homes, ageing systems and decades of extension work. ### Combis struggling in four-bedroom, two-bathroom homes A single combi asked to serve two showers at once will disappoint in almost every large Kent semi. Where demand is genuinely simultaneous, a system boiler with a correctly sized unvented cylinder is the right answer, and we will size it against actual usage rather than a rule of thumb. ### Ageing gravity-fed systems and failing cylinders Loft feed-and-expansion tanks, corroded copper cylinders and pinhole leaks are routine in inter-war Kent housing. We assess whether the system is worth upgrading or converting, and explain the cost difference honestly before you commit. ### Extensions added to an already-stretched system Side returns, rear kitchens and loft rooms are everywhere in Sidcup, Welling and Bexleyheath. Very few had the heating reassessed. Correct boiler sizing, a rebalanced circuit and sometimes zoning is what makes the whole house comfortable rather than just the ground floor. ### Sludge in decades-old steel radiators Cold bottoms, noisy pumps and kettling all point to magnetite. A chemical powerflush plus a magnetic filter restores output and is normally a condition of the warranty on a new installation. ### Undersized gas runs from older meters Inter-war properties frequently retain their original gas run. Before quoting a higher-output boiler we carry out a working-pressure and gas-rate test, and price any uprate up front rather than raising it halfway through the job. ### Uncertified or unserviced unvented cylinders Unvented hot water must be installed and serviced by a G3-qualified engineer. Flat expansion vessels, discharging tundishes and missing service records are common and are both a safety and a warranty issue.

Kent FAQ ## Answers beforeyou commit. Not covered here? Call Ian directly on 07460 067161. Which parts of Kent do you cover?The North West Kent and London border corridor is our core area — Sidcup, Bexley, Bexleyheath, Welling, Chislehurst, Foots Cray, Blackfen and Albany Park. Jobs further into Kent are considered case by case; call 07460 067161 and we will tell you honestly whether we can reach you. Should I fit a combi or a system boiler and cylinder in a large Kent house?It depends on how many bathrooms you use at the same time. A single-bathroom home is usually well served by a combi; a four-bedroom, two-bathroom house typically performs far better on a system boiler with a correctly sized unvented cylinder. Ian is G3 qualified for unvented work, so the recommendation is based on the property rather than on what is easiest to install. Can you upgrade an old gravity-fed system rather than replace everything?Often, yes. Where the cylinder and pipework are sound, a modern system boiler with proper controls and a good pump can be excellent value. Where the pipework is heavily sludged or the cylinder is failing, replacement is the better long-term decision — and we will say which applies to your property after seeing it. Do you issue Landlord CP12 certificates in Kent?Yes. Every appliance is tested and the Landlord Gas Safety Record is issued digitally the same day under Gas Safe 952303. With your authorisation we can arrange access with tenants directly. How quickly can you attend an urgent breakdown on the Kent border?Sidcup, Bexleyheath, Welling and Chislehurst are inside the core daily area, so urgent no-heat and no-hot-water calls are usually attended same-day or next-day, subject to availability. What does a boiler installation typically cost in Kent?Boiler installations in Kent 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 Kent?Yes — out-of-hours cover is available in Kent, 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 Kent?Always. For installations and larger jobs we assess on site, then send a written fixed-price estimate. Nothing starts until you've accepted it in writing. Is the work guaranteed in Kent?Yes. Every job carries a 12-month workmanship guarantee. 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. Every gas job in Kent is carried out and certified by a registered engineer, and our number appears on every certificate. Do you subcontract work in Kent?No. Ian Fisher, the owner, personally carries out or supervises every job in Kent. One point of contact from first call to twelve-month follow-up.
