What this covers: a new or replacement gas boiler — choosing the right type for the property, what the law requires of a new install, and the paperwork that protects your warranty and your home’s sale. The sections below cover the choice, the rules, and the Newham-specific question of where a new boiler and its flue can actually go.
Routing: if your current boiler has just broken and you’re deciding whether to mend it, start with boiler repair or the repair-or-replace guide; the annual service that follows an install has its own page.
Costs: a planned quote covering the boiler, controls, fitting and any system work. See What it costs below.

Choosing the right boiler
The right boiler depends on the property and how it uses hot water, not on what’s cheapest on the day.
Combi boilers heat water on demand with no cylinder, which suits flats and smaller homes with one bathroom — a big part of Newham’s stock. System boilers use a hot-water cylinder and suit larger homes or those with more than one bathroom, where several taps may run at once. Heat-only (regular) boilers, with a cylinder and a feed tank, are often the like-for-like replacement in older terraced houses already set up for them. Switching type — say, a heat-only to a combi — is more involved and costs more, because it changes the pipework and removes tanks. The combi vs system guide goes into the trade-offs.
Whatever the type, this is a hard-water borough, and that affects the install. Thames Water classes all its supplies as hard, so limescale and sludge shorten a system’s life.1 A good installer will flush the system and fit a magnetic filter as part of the job — both protect the new boiler and are increasingly expected as standard practice.
What the law requires
A new gas boiler in England is regulated work, and a compliant install generates specific paperwork. It’s worth knowing what to expect so you can check you’ve received it.
Efficiency and controls (Boiler Plus). Since 2018, every new or replacement gas boiler in England must be at least 92% ErP efficiency — effectively a condensing boiler — and the install must include time and temperature controls (a programmer and room thermostat).2 If you’re fitting a combi, the rules require one of four extra energy-saving measures: flue gas heat recovery, weather compensation, load compensation, or smart controls.2
Gas Safe and Building Regulations. Installing a gas boiler is notifiable work under the Building Regulations. By law it must be done by a Gas Safe registered engineer — the HSE requires the business to be on the Gas Safe Register for gas work.3 A Gas Safe registered installer self-certifies the work and notifies the local authority (via the Gas Safe Register) within 30 days, after which you should receive a Building Regulations Compliance Certificate by post.4 Keep it — it belongs to the property and a buyer’s solicitor will ask for it when you sell or remortgage.
The Benchmark record. Most manufacturers require the installer to complete a Benchmark commissioning checklist in the boiler’s logbook at handover, and to register the warranty. Without it, the warranty can be invalid — so make sure it’s filled in and the warranty is registered in your name.
The two documents to walk away with: the Building Regulations Compliance Certificate, and the completed Benchmark/commissioning record with your warranty registered. Both protect you later.
Where it can go in Newham
In Newham, where a new boiler can go is often a building question before it’s a boiler question — because so much of the borough is flats.
The Office for National Statistics records flats rising to 54.6% of Newham’s dwellings by 2021, the largest increase of any local authority in England.5 In a flat, a new boiler raises questions a house doesn’t: where the flue can terminate, whether it’s a communal or shared flue, and whether your lease or the freeholder/managing agent needs to consent to the work and the flue position. It’s worth checking the lease and asking the managing agent before booking, so the install isn’t held up on the day.
There’s also a conservation angle for a minority of homes. Newham has nine conservation areas, and three carry Article 4 directions controlling external alterations. A boiler itself is internal, but a new external flue terminal on a front or street-facing elevation in a conservation area can be the one part of the job where you should check whether consent is needed before it goes in — the council’s conservation-areas pages set out which areas and controls apply.6 For most homes this won’t arise; it’s worth a check only on protected frontages.
Find a verified installer by district
Newham’s installs split by building type as much as by boiler type.
East Ham, Forest Gate, Manor Park and Plaistow (E6 / E7 / E12 / E13). The terraced and converted-house belt, where like-for-like combi and system swaps are common — and where a hard-water flush and filter, and sometimes a flue or condensate route to sort, are the practical issues.
Stratford, Stratford City, East Village and the Royal Docks (E15 / E16 / E20). Modern managed flats where the flue, the lease and the managing agent often decide what’s possible — confirm consent and flue position before an installer quotes.
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 much of the stock is newer managed building with boilers already in place; here an install is more often a replacement within a managed block than a fresh fit.7
The conservation-area streets — Forest Gate, East Ham, Manor Park (Durham Road), Stratford St John’s, Sugar House Lane and Three Mills. Ordinary internal installs are unaffected, but a new external flue on a protected frontage is worth checking first.
Safety first
A new boiler is a planned job, but it’s still a gas appliance, so the gas safety rules apply.
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:8
- Don’t touch anything electrical — no switches on or off, no naked flames, no smoking.
- Open doors and windows if it’s safe, to ventilate.
- 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).
- Leave the property if the smell is strong or you feel unwell.
- Call the National Gas Emergency Service on 0800 111 999 from outside — free, 24 hours.
Carbon monoxide. A correctly installed, compliant boiler is the best protection against carbon monoxide, which the Health and Safety Executive warns you cannot see, taste or smell.10 Under the Building Regulations (Approved Document J), since October 2022 a carbon monoxide alarm must be fitted when a new or replacement gas appliance such as a boiler is installed in a home in England — so a compliant install includes one; make sure it’s fitted and working.9
Use a Gas Safe registered installer — and check the card. Only a Gas Safe registered engineer can legally install a gas boiler.3 Ask to see the ID card and check it covers boiler installation before work starts; an unregistered install is illegal, dangerous and will not be properly notified or certified.
Renting? A landlord, not a tenant, arranges a boiler replacement. If you’re a Newham Council tenant, you don’t buy your own boiler — the council’s Repairs & Maintenance Service handles boiler replacement and gas work on council homes, and RMS staff carry a Newham Council/RMS ID card.11
What it costs
A boiler installation is a planned quote covering the boiler, controls, fitting and any system work. The figures below are a general guide for London, not a quote.
| Job type | Indicative range (London) |
|---|---|
| Combi swap (like-for-like) | £1,800–£3,000 |
| New system or heat-only boiler | £2,200–£3,500 |
| Conversion (e.g. heat-only to combi) | £3,000–£4,500+ |
| System flush + magnetic filter (with install) | £200–£600 |
| Controls upgrade (smart thermostat) | £150–£350 |
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. Always get at least a couple of written quotes that itemise the boiler, controls, flushing and any extra work, and confirm the warranty length. For reading a quote, see how to read a plumbing quote and the London plumbing costs guide.
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.12 An installer using a non-compliant vehicle may factor that into their pricing, so it’s reasonable to ask.
