Gas boiler ban UK: what the Future Homes Standard means for new and existing homes

The phrase "gas boiler ban" gets used for three different things: a rule for new homes that is now law, an old target for 2035 that never became law, and an obligation on boiler manufacturers, which is the nearest real thing to a "gas boiler tax". Mixing them up is how people end up thinking they must rip out a working boiler. They don't.

We read the government documents behind each one on 8 October 2026: the Future Homes Standard regulations and consultation response, the 2021 Heat and Buildings Strategy, the October 2025 Carbon Budget and Growth Delivery Plan, the Warm Homes Plan, the Clean Heat Market Mechanism guidance and the Scottish Government's heat publications. This guide sets out what each one says and leaves out anything we couldn't trace to one of them.

Are gas boilers being banned in the UK?

No. We found no law in England or Scotland that bans gas boilers in existing homes, and you can still replace an old or broken gas boiler with a new one. The change is for new homes: from 24 March 2027, new homes in England must meet the Future Homes Standard, which is built around heat pumps and other low-carbon heating.

Here is where each part of the UK picture stood when we checked.

Existing homes: what the rules say about gas boilers

If you live in a home that already has a gas boiler, the current rules let you keep it, repair it and replace it with another gas boiler. The government's plans rely on people choosing low-carbon heating when an old system wears out, not on a cut-off date.

The Carbon Budget and Growth Delivery Plan (October 2025) puts it this way: by the early 2030s, the government expects over one million existing homes a year to move to low-carbon heating "as part of the normal cycle of replacing an existing heating appliance (such as a gas boiler) at the end of its life". It adds that by 2035, low-carbon heating will represent the vast majority of all heating system replacements. Those are expectations in a plan. They aren't rules that apply to your home.

The Warm Homes Plan (January 2026) is written in the same spirit. It says "consumer choice is at the heart of the Warm Homes Plan" and wants heat pumps to "increasingly become the desirable and natural choice for households replacing an existing heating system at the end of its life". The tools it uses are grants, lower electricity costs and rules for new homes.

Boiler Plus: the one condition on new gas boilers in England

There is one rule worth knowing before you book an install. Boiler Plus, in force since 2018, requires existing households in England to install an additional energy saving measure from a choice list when a new or replacement combi gas boiler goes into an existing home. The Carbon Budget and Growth Delivery Plan describes it in those terms. Your installer should explain which measure they are fitting and why.

Off-gas-grid homes

The previous government proposed, in October 2021, to restrict fossil fuel heating installs in homes off the gas grid by 2026. The Carbon Budget and Growth Delivery Plan says the current government "will not take forward" that proposal and will consult on any future proposals for off-gas-grid homes. If you heat with oil or LPG, nothing changed in 2026 on that front.

Hydrogen boilers

If you've heard that hydrogen will replace natural gas in home boilers, the same plan says hydrogen is "not yet a proven technology for home heating" and that any role "would come much later and would likely be limited". The government says it will consult in due course. We wouldn't plan a heating decision around it.

What is the Future Homes Standard?

The Future Homes Standard is the set of energy and carbon rules that new homes in England must meet under the Building Regulations. The law behind it is The Building Regulations etc. (Amendment) (England) Regulations 2026, made on 23 March 2026 and laid before Parliament on 24 March 2026. The Ministry of Housing, Communities and Local Government published its consultation response the same day, together with a matching standard for non-domestic buildings, the Future Buildings Standard.

According to the consultation response, new homes built to the standard will be built with low-carbon heating, high levels of energy efficiency and, in most cases, solar panels. The government's aim is that they "will not require retrofitting to become zero carbon in use once the electricity grid is fully decarbonised". In plain terms, a new house shouldn't need its heating replaced later to reach zero carbon.

The Building Circular sent to councils and building control bodies lists the main legal changes. They include:

• a new requirement, L3, for on-site renewable electricity generation on new homes
• a new regulation, 40C, on information that must be given to the homeowner
• routes for connecting new homes to heat networks
• updated guidance on heat pumps

The circular is clear that these changes apply in England only.

Future Homes Standard dates

The headline date is 24 March 2027. The detail matters if you are buying off-plan, because a home finished after that date can still be built to the older rules if the development qualifies for the transition.

The transition works like this. Where building control documents were submitted before 24 March 2027 and work starts before 24 March 2028, a development can still be built under the 2021 version of Part L, the energy part of the Building Regulations. So some new homes with gas boilers will still be completed after March 2027. If you are buying a new build in 2027 or 2028, ask the developer which version of the regulations the plot was built under.

Higher-risk buildings, such as taller blocks of flats, follow the separate date of 24 September 2027. To keep using the 2021 rules, a valid Gateway 2 application has to be made before then.

Will new build homes have gas boilers?

The Future Homes Standard doesn't name gas boilers as banned. The consultation response notes that some people who replied asked for technologies such as gas boilers to be banned. The government's answer was that the Building Regulations will keep their performance-based approach. The law sets a level of performance and the designer chooses how to reach it.

In practice, the target is set so that gas is very hard to use. The final stage impact assessment explains that each new home is measured against a model home, the notional dwelling, which includes "a heat pump, wastewater heat recovery, improved airtightness and decentralised mechanical extract ventilation". A developer's design has to perform as well as that model. The same assessment says "new homes will no longer rely on fossil fuels". And the consultation response says boilers "are unlikely to be present in new buildings, given the guidance on carbon intensity of fuel used for heat".

Our reading: calling it a ban on gas boilers in new homes isn't accurate in law, but most buyers will see the same result. Expect a new home in England built to the standard to have a heat pump or a connection to a heat network.

What happened to the 2035 gas boiler ban?

The 2035 date comes from the Heat and Buildings Strategy, published by the previous government in October 2021. It said: "Our ambition is to phase out the installation of natural gas boilers beyond 2035." The same document also said: "No-one will be forced to remove their existing boilers."

That was an ambition in a strategy paper. We found no regulation that put a 2035 cut-off for gas boilers into law. The current government's October 2025 delivery plan doesn't restate it as a ban. It talks about an expectation that low-carbon heating will be the vast majority of heating replacements by 2035, reached through the normal replacement cycle.

Policy can change again, and we'll update this page if it does. On the documents in force today, a 2035 ban on gas boilers in existing homes isn't something you need to plan around.

Is there a gas boiler tax?

We found no tax on households for owning or installing a gas boiler in any of the government documents we read. Two real policies are close to what people tend to mean by the phrase: an obligation on boiler manufacturers, and changes to which energy bills carry policy costs.

The Clean Heat Market Mechanism

The Clean Heat Market Mechanism is an obligation on manufacturers that supply gas and oil boilers to the UK market. It started on 1 April 2025, applies across the whole UK, is run by the Environment Agency and will last until at least 2029. It is set out in the Clean Heat Market Mechanism Regulations 2025 under the Energy Act 2023.

Each year, a manufacturer in the scheme has a target for heat pump installs in existing homes, in proportion to the fossil fuel boilers it sells. It meets the target by supplying heat pumps or by buying credits from companies that do. The scheme covers manufacturers that supply 20,000 or more gas boilers, or 1,000 or more oil boilers, in a year. Small companies are excluded.

The target is rising. The government response for scheme year 2 set it at 8% of relevant boiler sales for 2026 to 2027, up from 6% in the first year. Nothing in the guidance charges households. Whether manufacturers pass any cost into the price of a new boiler isn't covered in the government documents, so we can't tell you how much, if anything, it adds.

Moving policy costs between gas and electricity bills

The other change is about bills, not boilers. The Warm Homes Plan says the government "removed some policy costs from electricity bills" because costs falling disproportionately on electricity bills had led to "an unfair distortion in relative gas and electricity prices". It says an average of £150 of costs came off energy bills from April 2026. A June 2026 government factsheet describes this as "taking the costs of some historic levies into general taxation".

The Budget 2025 measures behind this included "ending the Energy Company Obligation and funding 75% of the domestic cost of the legacy Renewables Obligation for 3 years", according to the Warm Home Discount cost recovery response. That same response moved the cost of the Warm Home Discount from the standing charge to the unit rate on both gas and electricity from 1 April 2026. Its own example: a gas-heated home with high demand due to medical needs could see its bill rise by around £29 from that move alone, but is expected to see about £195 of net costs removed once the wider Budget measures are counted.

The Future Homes Standard impact assessment mentions "future policies such as rebalancing the levies on gas vs electricity". We found no confirmed decision to add new levies to gas bills in the documents we read.

Gas boiler rules in Scotland

Scotland moved first on new buildings. The New Build Heat Standard, standard 6.11 of the Building (Scotland) Regulations 2004, came into force on 1 April 2024. The Scottish Government's assessment describes its aim as being "to prohibit the use of direct emissions heating systems in new buildings applying for a building warrant from 1 April 2024 onwards". A zero direct emissions heating system, such as a heat pump, is needed instead. It also applies to some conversions.

In September 2024 a Direction made temporary changes so that wood burning stoves and some other bioenergy systems could be installed in new buildings. That doesn't bring gas boilers back.

For existing homes, Scotland has no gas boiler ban in force. In November 2025 the Scottish Government published a draft Heat in Buildings Bill and said it intended to introduce it once the Scottish Parliament returned after the May 2026 election (Heat in buildings: future plans). The same page says it is committed to decarbonising heat in buildings by 2045. Its Programme for Government 2026 to 2031, published on 1 September 2026, says the Bill's primary purpose is "to reduce direct emissions from heating Scotland's buildings".

We couldn't confirm whether the Bill has been introduced to the Scottish Parliament, or what it will require of existing homes. If you live in Scotland, treat any claim about a ban in existing homes with care until the Bill is published in final form. Our Scotland page covers the heating grants available there now.

If your gas boiler is old or broken now

You can still replace a gas boiler in an existing home with a new gas boiler. In England, a combi install also needs the extra Boiler Plus measure. Use an engineer you can check, and our guide to checking Gas Safe and TrustMark shows how. If you want to move away from gas instead, the grants are larger than they used to be.

ECO4, for eligible households, until 31 December 2026

The Energy Company Obligation can help with "replacing or repairing your boiler", according to GOV.UK. For private housing, someone in the home needs a qualifying benefit, such as Universal Credit, Pension Credit, Housing Benefit or income-related ESA. Owners need an energy rating of D to G, and private renters need E to G plus the owner's permission. ECO4 ends on 31 December 2026 (SI 2026/361). Our free boiler scheme guide and broken boiler replacement guide cover how it works, and what the deadline means explains the timing.

The Boiler Upgrade Scheme, for a heat pump

If you'd rather switch, the Warm Homes Plan sets the Boiler Upgrade Scheme grant at £7,500 for heat pumps that run radiators, known as hydronic heat pumps, in England and Wales. It added £2,500 for air-to-air heat pumps and heat batteries. See our air source heat pump grant guide and the air-to-air heat pump grant guide.

Warm Homes: Local Grant, in England

Councils in England run the Warm Homes: Local Grant for privately owned homes rated D to G. GOV.UK says household income usually needs to be £36,000 or less, or you live in certain postcodes, or you get certain benefits. The council arranges the work and pays for it (GOV.UK). The Warm Homes Plan guide explains how this fits with the other schemes.

Our view, given the interest we've declared: if your boiler works and is safe, nothing in the law gives you a reason to replace it early. If it has broken down and you get one of the qualifying benefits, check ECO4 before you pay for anything, because the scheme closes at the end of the year.

What the gas boiler rules mean for you

If someone tells you a gas boiler ban means you must act now, ask them which law they mean. Our guide to spotting grant scams lists other warning signs.

About this guide

Who wrote it: the ApplyFreeBoiler Team. ApplyFreeBoiler.uk is run by Reliant Energy Solutions Ltd, an ECO4 heating and insulation installer. We wrote this because households ask us whether it is still worth replacing a gas boiler, and the answer depends on which rule they have heard about.

How we checked it: every rule and date was checked on 8 October 2026 against GOV.UK, legislation.gov.uk, documents from the Department for Energy Security and Net Zero and the Ministry of Housing, Communities and Local Government, and Scottish Government publications. Quotes are copied from those documents.

What we couldn't confirm: whether Scotland's Heat in Buildings Bill has been introduced and what it will require of existing homes, and what the Clean Heat Market Mechanism adds to boiler prices. We didn't review building regulations in Wales or Northern Ireland.

Updates: we'll review this page when the Future Homes Standard comes into force on 24 March 2027, and sooner if the Scottish Bill is introduced or UK heating policy changes.
