Boiler Repairs &
Heating in Lewisham
Lewisham's Victorian terraces, converted flats and modern town-centre blocks all keep us busy in SE13. Ian Fisher — Gas Safe 952303 — attends personally for breakdowns, installations, services and landlord gas safety certification.
Working in Lewisham,
not just passing through.
Lewisham has one of the highest concentrations of converted flats and shared houses in South East London. That shapes the work: multiple gas appliances per building, shared risers, boilers in internal cupboards, and landlords who need reliable annual certification rather than chasing.
For HMOs and multi-let houses, every gas appliance requires an annual Landlord Gas Safety Record. We certify the whole property in one visit where access allows, issue the record digitally the same day, and quote any remedial work separately in writing.
The Victorian terraces behind the town centre bring the usual SE London constraints — long gas runs, small-bore sludged circuits, and boilers well past economic repair. The modern blocks around Loampit Vale bring pressurised systems where the fault is usually diagnostic rather than terminal.
Everything is carried out by Ian Fisher personally under Gas Safe registration 952303, with a written fixed-price estimate before work begins and a 12-month workmanship guarantee after.

What we see
most often in Lewisham.
Lewisham's dense mix of conversions, terraces and modern flats produces a distinct, repeatable fault profile.
Multiple appliances needing annual certification
Converted houses often have several boilers, cookers and fires across separate lets. Coordinating one visit and certifying everything together saves landlords repeat call-out charges.
Boilers in internal cupboards with marginal flues
Conversion-era installations sometimes have flue terminations or clearances that no longer comply. We identify and correct these rather than certifying around them.
Repeated pressure loss in apartment systems
Modern SE13 blocks commonly present with sealed systems that will not hold pressure. Expansion vessel failure, passing relief valves and small circuit leaks are the usual causes.
Sludged small-bore circuits in Victorian terraces
Cold radiator bottoms, kettling and noisy pumps mean magnetite. A full powerflush and magnetic filter is essential before commissioning a new boiler.
Tenant-reported faults left unresolved
Intermittent hot water, low pressure and noisy boilers reported repeatedly usually have one underlying cause. We diagnose properly so the same job does not come back next month.
The same methodical process,
wherever we work.

Do you handle HMO gas safety certificates in Lewisham?
Yes. Every gas appliance in the property is tested and recorded, the installation pipework is checked and the Landlord Gas Safety Record is issued digitally the same day under Gas Safe 952303.
Can you deal directly with my tenants for access?
Yes — with your authorisation we contact tenants directly to arrange access, which is usually the fastest way to complete certification or a repair in a multi-let SE13 property.
How quickly can you attend a Lewisham boiler breakdown?
SE13 is central to our routes, so urgent no-heat and no-hot-water calls are commonly attended same-day or next-day, subject to availability. Call 07460 067161.
What does a boiler installation typically cost in Lewisham?
Boiler installations in Lewisham 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 Lewisham?
Yes — out-of-hours cover is available in Lewisham, 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 Lewisham?
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 Lewisham?
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 Lewisham is carried out and certified by a registered engineer, and our number appears on every certificate.
Do you subcontract work in Lewisham?
No. Ian Fisher, the owner, personally carries out or supervises every job in Lewisham. 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 Lewisham. No VAT is currently charged.
