Plumbing & Heating
Across Middlesex
We cover Middlesex regularly from our Covent Garden base — Twickenham, Hounslow, Uxbridge, Harrow, Ruislip, Ealing, Wembley and Enfield borders — for boiler installation, repair, servicing, CP12 landlord certificates and complete central heating.
Working in Middlesex,
not just passing through.
Middlesex is the classic Metroland belt — 1930s three- and four-bedroom semis in vast numbers across Harrow, Wembley, Ealing, Uxbridge and Ruislip, plus dense terraced housing closer to Hounslow and Twickenham. It's exactly the housing Ian knows best.
We work these postcodes constantly — TW, UB, HA, HW and closer W and NW postcodes — for combi replacements, system upgrades on extended homes, and CP12 rounds on landlord portfolios.
Same standard as every job — Ian personally attends, Gas Safe 952303, written fixed-price estimate first.

What we see
most often in Middlesex.
Middlesex is dominated by one housing type — the Metroland semi — and its typical heating faults are very well characterised.
Original back-boiler replacements
Vast numbers of Middlesex 1930s semis still run original back-boilers behind gas fires. Replacement with a modern combi frees the chimney breast, drops the gas bill and gives predictable hot water.
Sludge and cold radiator bottoms
The 90-year-old small-bore steel pipework is a magnet for magnetite sludge. A powerflush and magnetic filter almost always restore full radiator output — and are a warranty condition on most new boilers.
Extended homes with under-sized systems
Rear and side extensions added to 1930s semis often outpace the original heating system. Upsizing radiators, adding a circuit, or upgrading to a system boiler with unvented cylinder usually solves it.
Loft-conversion en-suites
Loft conversions with en-suites in Harrow, Ruislip and Pinner often disappoint on shower pressure because the combi wasn't sized for a third bathroom. We recalculate demand and specify properly.
Landlord CP12 across Middlesex portfolios
Middlesex has active landlord portfolios, particularly around Hounslow, Southall and Wembley. We batch CP12 renewals and issue certificates the same day.

How quickly can you attend in Middlesex?
Twickenham, Hounslow, Ealing, Wembley, Harrow, Ruislip and Uxbridge are typically same or next day for urgent boiler faults.
What does a boiler installation typically cost in Middlesex?
Boiler installations in Middlesex 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 Middlesex?
Yes — out-of-hours cover is available in Middlesex, charged at £150/hr. For genuine emergencies (gas leaks, no heat with vulnerable occupants) call 07801 550790 directly and Ian will advise on response time.
Do you provide a written estimate before starting work in Middlesex?
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 Middlesex?
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 Middlesex is carried out and certified by a registered engineer, and our number appears on every certificate.
Do you subcontract work in Middlesex?
No. Ian Fisher, the owner, personally carries out or supervises every job in Middlesex. One point of contact from first call to twelve-month follow-up.
