Heating & Plumbing
Engineer in Greenwich
Greenwich combines Georgian and Victorian conservation-area housing with new riverside apartments at Greenwich Peninsula. Ian Fisher — Gas Safe 952303, G3 Unvented certified — works sensitively in both, with written fixed-price estimates before anything starts.
Working in Greenwich,
not just passing through.
Greenwich is dominated by conservation-area housing, and that changes how heating work is planned. Flue terminal positions, external condensate routing and any visible pipework need thinking through before the estimate is written, not improvised on installation day.
The townhouses here are tall and narrow — three or four storeys with bathrooms distributed up the building. Hot-water performance at the top floor is the recurring complaint, and it is usually solved with a system boiler and correctly sized unvented cylinder rather than a bigger combi.
Converted period flats bring their own issues: shared risers, boilers in internal cupboards, and freeholder or managing-agent consent for anything affecting the external envelope. We supply the documentation agents ask for and work within building rules.
On the Peninsula, the picture is entirely modern — pressurised systems, compact plant, and faults that are usually commissioning or expansion-vessel related rather than equipment failure. Diagnosis before replacement is the rule.

What we see
most often in Greenwich.
SE10 problems divide neatly between period-property constraints and modern apartment commissioning faults.
Top-floor showers with poor pressure and flow
Tall Greenwich townhouses defeat combis at the top of the building. An unvented cylinder sized to real simultaneous demand, or a properly specified pump arrangement, fixes it permanently.
Flue routing restricted by conservation rules
Where an external terminal is unacceptable or non-compliant, the appliance position, a vertical flue or a rerouted condensate becomes part of the design — planned before quoting.
Cast-iron and period radiators loaded with magnetite
Large-volume period emitters hold decades of corrosion. Powerflushing, re-valving and correct inhibitor dosing protect any new boiler.
Peninsula apartments with default boiler settings
Flow temperatures, pump settings and controls left as delivered waste gas and produce uneven heating. Recommissioning frequently resolves complaints without new equipment.
High heat loss in single-glazed period rooms
Sash windows and solid walls raise the heat load well above standard assumptions. Room-by-room calculation prevents undersized radiators being installed all over again.
The same methodical process,
wherever we work.

Can you install a boiler in a Greenwich conservation-area property?
Yes. We plan the flue terminal position, condensate route and any visible pipework in advance to minimise external impact, and discuss anything visible with you — and where relevant your freeholder or managing agent — before booking.
Why is hot water weak on the top floor of my Greenwich townhouse?
Usually because a combi or an undersized cylinder cannot maintain flow at height and distance. A system boiler with a correctly sized unvented cylinder, commissioned to G3 standard, is the normal solution.
Do you cover Greenwich Peninsula apartments?
Yes — including modern pressurised systems in compact plant cupboards. Most Peninsula faults we attend are commissioning, expansion vessel or control problems rather than failed appliances.
What does a boiler installation typically cost in Greenwich?
Boiler installations in Greenwich 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 Greenwich?
Yes — out-of-hours cover is available in Greenwich, 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 Greenwich?
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 Greenwich?
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 Greenwich is carried out and certified by a registered engineer, and our number appears on every certificate.
Do you subcontract work in Greenwich?
No. Ian Fisher, the owner, personally carries out or supervises every job in Greenwich. One point of contact from first call to twelve-month follow-up.
Which payment methods do you accept?
Bank transfer and card payments are both accepted for jobs in Greenwich. No VAT is currently charged.
