Coverage: Stratford, Stratford City, East Village, West Ham, Plaistow, Upton Park, East Ham, Forest Gate, Manor Park, Little Ilford, Green Street, Canning Town, Custom House, Beckton, Royal Docks, Silvertown, North Woolwich, West Silvertown, Maryland, Gallions Reach, Cyprus, Plashet, South Beckton and Temple Mills — covering E6, E7, E12, E13, E15, E16 and E20.

What this covers: the annual boiler service — the preventive check that keeps a boiler running safely and efficiently — and, for landlords, the separate legal duty of an annual gas safety check and its CP12 record. The sections below explain what a service involves, how it differs from the landlord’s legal check, and why both matter in a hard-water borough.

Routing: if the boiler is actually faulty — a fault code, no heat, a leak — that’s boiler repair, not a service; a new boiler and central heating problems have their own pages.

Costs: a fixed-price service, a little more if combined with the landlord gas safety check. See What it costs below.

What a service involves

A service is preventive — it’s booked when the boiler’s working, to keep it that way and to catch problems early.

A Gas Safe registered engineer will typically check the boiler is burning correctly and safely, inspect the flue and combustion, check gas pressure and flow, examine seals and electrical connections, test the safety devices and controls, and look over the visible pipework and condensate. On many boilers the engineer also cleans key components. The point is to spot wear, blocked flues, leaks or poor combustion before they become a breakdown — or, more seriously, a carbon monoxide risk.

There’s a hard-water angle that matters in Newham. Thames Water classes all its supplies as hard, and limescale builds up in boilers and heat exchangers over time, which dulls efficiency and shortens a boiler’s life.¹ A regular service — and emptying any magnetic filter on the system — keeps scale and sludge in check, which is why an annual service tends to earn its cost back in efficiency and avoided repairs here.

The service vs the legal check

This is the distinction that trips people up: the annual service and the landlord’s annual gas safety check are not the same thing.

The gas safety check (CP12) — a landlord’s legal duty. If you let a property with gas appliances, the law requires an annual check, not just a good intention. Under the Gas Safety (Installation and Use) Regulations 1998, a Gas Safe registered engineer must check the gas appliances and flues the landlord provides every 12 months, and issue a Gas Safety Record (the CP12).² Landlords must also keep installation pipework safely maintained — though pipework is not itself covered by the annual check, so it’s good practice to ask the engineer to test the system for soundness and examine the pipework at the same time. The landlord must give a copy of the record to existing tenants within 28 days of the check and to new tenants before they move in, and keep it for at least two years; the check can be done up to two months early while keeping the same renewal date. Failing to comply is a criminal offence — and since October 2022, landlords in England must also provide a carbon monoxide alarm in any room with a fixed combustion appliance such as a boiler.

The service — best practice, not the same as the check. A full service goes further than the safety check, cleaning and maintaining the boiler to keep it efficient and reliable. It isn’t legally required to service the boiler at the same time as the safety check, but doing both together is sensible and many engineers offer them as one visit. For an owner-occupier there’s no legal check at all — just the service, which keeps the warranty valid (most manufacturers require an annual service) and the boiler safe.

The Newham licensing link. There’s a local reason landlords here can’t let the check slip: Newham operates property licensing across most of the borough — all wards except Royal Victoria and Stratford Olympic Park — and a landlord’s licence requires evidence of the gas safety check, so the CP12 is part of letting legally in Newham, not just a safety formality.³

Find a verified engineer by district

Newham’s servicing demand is shaped by how much of the borough is let.

The terraced and converted-house belt — East Ham, Forest Gate, Manor Park, Plaistow, Green Street and Upton Park (E6 / E7 / E12 / E13). A large private-rented sector here means a lot of landlord gas safety checks alongside owner-occupier services — and older boilers in a hard-water area benefit most from a regular service.

Stratford, Stratford City, East Village and the Royal Docks (E15 / E16 / E20). Modern managed blocks where a service or safety check on a boiler in a communal or plant arrangement can need building-management access — worth arranging before the engineer attends.

Canning Town and Custom House (E16). Part of Newham’s £3.7 billion regeneration programme — 10,000 new homes, 3,500 already completed or on site, the council says — so newer managed buildings where access and warranty-driven annual servicing on relatively new boilers are common.⁴

Safety first

A service exists largely to keep a gas appliance safe — but if you ever suspect a problem, don’t wait for the next service.

If you smell gas or suspect a leak. Natural gas has a strong “rotten egg” smell added to it. The Health and Safety Executive and the National Gas Emergency Service set out a clear order:⁵

1. Don’t touch anything electrical — no switches on or off, no naked flames, no smoking.
2. Open doors and windows if it’s safe, to ventilate.
3. Turn off the gas at the meter control valve if you know where it is and can reach it safely (unless the meter is in a cellar).
4. Leave the property if the smell is strong or you feel unwell.
5. Call the National Gas Emergency Service on 0800 111 999 from outside — free, 24 hours.

Carbon monoxide. Catching CO risk is one of the main reasons a service matters. A boiler burning poorly can produce carbon monoxide, which the Health and Safety Executive warns you cannot see, taste or smell — symptoms include headaches, dizziness, nausea and tiredness.⁶ Every home with a gas appliance should have an audible CO alarm; if one sounds, treat it as an emergency.

Gas work is Gas Safe only. A service or safety check must be carried out by a Gas Safe registered engineer — the HSE requires the business to be on the Gas Safe Register for gas work.⁷ Always ask to see the ID card, which shows what work the engineer is registered for.

Council tenants. If you’re a Newham Council tenant, you don’t arrange your own boiler service — the council’s own Repairs & Maintenance Service carries out the annual gas safety check on council homes, writing to you with an appointment; RMS staff carry a Newham Council/RMS ID card, and you shouldn’t admit anyone for a gas check who can’t show one.⁸

What it costs

A boiler service is usually a fixed price, with the landlord gas safety check priced similarly or combined. The figures below are a general guide for London, not a quote.

Editorial estimate only. These figures are an indicative guide to help you plan — they are not regulated rates, not market data, and not a published cost survey. Confirm whether a quote is for a full service, a safety check, or both. For reading a quote, see how to read a plumbing quote and the London plumbing costs guide, and for landlords, the landlord plumbing compliance checklist.

Newham is within the London-wide Ultra Low Emission Zone, which Transport for London operates 24 hours a day across every London borough, with a daily charge for vehicles that don’t meet its emissions standards.⁹ An engineer using a non-compliant vehicle may factor that into their pricing, so it’s reasonable to ask.
