This page is for problems with the heating system — radiators, pipework, the pump, valves and the system water. If the fault is the boiler itself, locking out or showing a fault code, that’s Boiler Repair; for a routine service, Boiler Servicing; and for a new boiler, Boiler Installation.

Every listing is checked before it goes live and re-verified annually — public liability insurance evidence checked, business identity and named contact validated, and Gas Safe registration confirmed against the Gas Safe Register where gas work applies. No paid placements go live without verification.

Common central heating faults

Heating problems usually show up in the system rather than the boiler box. A heating engineer will diagnose the cause before quoting:

• Cold radiators, or cold at the top or bottom — air trapped at the top often means bleeding is needed; cold at the bottom across several radiators usually points to sludge settling in the system.
• Some rooms warm, others cold — the system may need balancing so flow is shared evenly, or a thermostatic radiator valve (TRV) may have seized.
• No heat even though the boiler is running — a failed pump, a stuck motorised or zone valve, or a diverter valve sending hot water the wrong way.
• Heating won’t come on or off on schedule — a faulty thermostat, programmer or wiring centre.
• A leak on the system — at a radiator valve, a joint or a pipe run, rather than the boiler itself.
• Noisy pipes or radiators — air, circulation problems or scale and debris in the system.

Some of these are quick fixes; others point to a system that needs cleaning or a worn component replaced.

Who can work on your central heating

This is where heating differs from the boiler. The HSE sets out that a non-registered person may carry out “wet work” — installing water pipes and radiators for a heating system — but any work on the gas boiler itself, and the final connection of the water pipework to the boiler, must be done by a Gas Safe registered engineer.¹ In practice that means much of the system side — radiators, valves, pipework, flushing — can be done by a competent heating engineer, while anything touching the boiler is Gas Safe territory. Most engineers listed here are Gas Safe registered and can do both, and where gas work applies we’ve confirmed that registration. You can ask any engineer for their Gas Safe ID card, which shows the categories they’re qualified for, and check it on the Gas Safe Register.

A couple of small jobs are fine to do yourself — bleeding a radiator, or topping up system pressure. But the Gas Safe Register notes that if you find yourself bleeding radiators regularly, it’s likely hiding a wider system issue worth asking an engineer to check.²

Sludge, flushing and hard water

Over time, central heating systems accumulate sludge — a build-up of corrosion debris (magnetite) and, in a hard-water area, scale. It collects in radiators and pipework, creating cold spots, making the pump work harder and reducing how well the system heats. Tower Hamlets sits in Thames Water’s hard-water region, which adds scale to the mix — and in the borough’s older terraces and period conversions, where systems and narrow microbore pipework have had decades to fur up, it’s a common cause of poor heating.³

An engineer will diagnose whether the system needs a chemical flush or a power flush to clear it, usually followed by a corrosion inhibitor to protect it, and may suggest a magnetic filter to catch debris in future. Which approach suits depends on the system and how bad the build-up is — something to discuss after they’ve looked at it. The London Hard Water Guide covers the wider effects.

Communal and district heating

Worth checking before you book: some Tower Hamlets flats and estates are heated by communal or district systems rather than an individual one — for example estates on the Isle of Dogs served by the council’s Barkantine heat network. If your heat and hot water come from a central plant, there’s no individual system in your flat to repair, and a heating fault is dealt with by the building operator or managing agent rather than a private engineer. A listed engineer is who you need when you have your own heating system — common in the borough’s houses, period conversions and many private flats.

Safety first — gas and carbon monoxide

Heating-system work is mostly “wet” rather than gas work, but where there’s a gas boiler the safety basics apply.

If you smell gas or think there’s a leak, the National Gas Emergency Service advises you call 0800 111 999 straight away (free, 24 hours). Don’t smoke or light a match, don’t turn any electrical switch on or off (a spark can ignite gas), open doors and windows if it’s safe, turn off the gas at the meter control valve if you know where it is and can reach it safely, and leave and call from outside if the smell is strong or you feel unsafe.⁴

Carbon monoxide (CO) is colourless and odourless, and a poorly running gas appliance can produce it. Symptoms include headache, dizziness, nausea, breathlessness, collapse and confusion. If you suspect CO, get into fresh air, call 999 for severe symptoms or NHS 111 for advice, and report the appliance on 0800 111 999. The HSE recommends fitting a carbon monoxide alarm that meets BS EN 50291, sited and maintained in line with the manufacturer’s instructions.⁵

Flats, landlords and tenants

Tower Hamlets is rental-heavy — the private rented sector is the borough’s largest tenure, at around 38% of households — so heating repairs in let homes are common.⁶ If you rent privately, your landlord must keep the space-heating installation in repair under section 11 of the Landlord and Tenant Act 1985, so a heating fault is generally one to report to the landlord rather than fix yourself.⁷ Housing-association tenants — including those of landlords on the council’s partner-landlord list such as Poplar HARCA, Clarion, Gateway and Peabody — report to their landlord.⁸

If you’re a Tower Hamlets Council tenant, report a heating fault to the council repairs service on 020 7364 5015 — a total or partial loss of heating with no alternative heating available is treated as an emergency repair.⁹

What central heating repair costs in Tower Hamlets

Indicative estimates based on recent London jobs and market observations (2025–2026), not regulated rates — no official pricing data exists for private heating repair. Because this is a directory, always confirm the call-out fee and price directly with the engineer before booking. Costs vary by the fault, the system and access. VAT may apply.

A power flush is priced by system size and number of radiators. See the full London Plumbing Costs Guide →

Why verified engineers — not a general directory

Every listing is checked before going live and re-verified annually. We confirm the business is legitimately trading and verify the named contact; we check evidence of public liability insurance; where a heating engineer also carries out gas work we confirm Gas Safe registration directly with the Gas Safe Register; and we confirm the engineer covers Tower Hamlets E-postcodes before approving the profile. Profiles may be suspended or removed if credentials lapse or credible concerns are raised. See the full verification process →. No customer middleman fee — enquiries go directly to the engineer.

From cold radiators in a microbore-piped Spitalfields conversion to a sludged-up system in a Bow terrace or a stuck zone valve in a Canary Wharf flat, central heating faults are usually about the system around the boiler — and where the work touches the boiler itself, it must be done by a Gas Safe registered engineer. Every engineer listed here is verified and covering Tower Hamlets E-postcodes.
