The Future Homes Standard and New Build Heating

The Future Homes Standard is the performance level that new homes in England must meet so that they are built without fossil fuel heating. The government's own consultation states the intent plainly: new homes will not be built with fossil fuel heating, such as a natural gas boiler¹. The 2023 consultation goes further and names the technologies that fail: "This means gas boilers, including hybrid and hydrogen-ready boilers, will not meet the proposed standards."¹

The headline numbers are emissions, not fuel. An average semi-detached home built to the standard is expected to have 75% lower emissions than one built to 2013 standards¹, and the government has put the reduction at 75% to 80% against then-current Building Regulations². Solar panels are required as standard on new homes, with the standard to be implemented in early 2026³. Scotland has moved first and separately: the New Build Heat Standard has been in force since 1 April 2024, and fossil fuel gas and oil boilers cannot be used as a mains heating system in new-build homes and buildings there⁴.

For a household, the practical meaning is narrow but firm. The standard governs what is built, not what already stands. It does not require anyone to remove a working boiler from an older home, and it does not apply to existing dwellings. What it does is remove gas from the new-build market, which changes what a buyer of a new home is choosing between, and it sets the direction that retrofit policy is expected to follow later.

What the Future Homes Standard is and what it requires

The standard is a performance level for new dwellings, expressed as carbon and energy outcomes rather than as a list of permitted appliances. Its stated aim is to improve the energy efficiency and reduce the carbon emissions of new dwellings and non-domestic buildings so that they are zero carbon ready⁵. The government's earlier position was that the standard would ensure new build homes are future-proofed with low carbon heating and high levels of energy efficiency².

The emissions figures have been consistent across documents. The introduction of the standard, the government said, will ensure that an average home produces at least 75% lower CO2 emissions than one built to current energy efficiency requirements¹. A separate statement put an average semi-detached home at 75 to 80% less carbon dioxide than one built to current requirements². The parliamentary briefing gives 75% lower emissions than under 2013 standards for an average semi-detached home¹.

What drives that reduction is the removal of the gas boiler and the addition of on-site generation. Heat pumps become "the primary heating technology"¹, and solar panels are required as standard³. The standard is not, on the evidence published so far, a fabric revolution: the proposed new standard does not currently require an uplift to insulation requirements compared to existing standards¹. That is a significant point for anyone assuming the new homes will be sealed to a much higher level than current ones. The carbon saving comes mainly from the heat source and the roof, not from the walls.

For a household's energy independence, this is a real shift. A new home with a heat pump and solar generates part of its own heat and power and is not exposed to a gas connection for its heating. What remains is dependence on electricity: the grid, a supplier, and the tariff the household is on. A heat pump without a battery still draws from the grid at the times it runs, and solar output does not match evening demand without storage.

England or Scotland: which standard applies where

Two different regimes are running in parallel, and the difference matters more than any single figure.

In England, the Future Homes and Buildings Standards will be implemented via the Building Regulations etc. (Amendment) (England) Regulations 2026⁵. The 2023 consultation applies to England¹. The parliamentary briefing notes planned updates to requirements for new homes across England and Wales in 2025, Scotland in 2024 and Northern Ireland in 2026 or 2027¹, which is the clearest single statement of how the four nations diverge.

In Scotland, the New Build Heat Standard is already law. It is a requirement set out in law and comes into force from 1 April 2024⁴. It applies to all new buildings applying for a building warrant from April 2024, which need to install clean heating systems, and it also applies to some conversions⁴. Its purpose is to make sure that any new buildings are future-proofed by using clean heating systems which will not require future retrofit⁴.

Wales and Northern Ireland sit at different points again. The Welsh government maintains mandatory quality standards for new, rehabilitated and existing homes, consulted on between 18 January 2016 and 11 April 2016⁶, which is a separate and older strand of work. Northern Ireland is placed at 2026 or 2027 for its update¹.

The practical consequence is that a householder buying a new home needs to know which nation the property is in before assuming anything about its heating. A new home in Scotland cannot have a gas or oil boiler as its mains heating system⁴. A new home in England is being built towards a standard that gas boilers, hybrids and hydrogen-ready boilers will not meet¹, with the regulations made under an England-only instrument⁵.

Timeline: consultation, commencement and full compliance

The consultation history is longer than the implementation. The government consulted on the Future Homes Standard between 2019 and 2020¹, then on its technical proposals for meeting the standard from November 2023 to March 2024¹. The 2023 consultation was scheduled for 12 weeks from 13 December 2023 to 6 March 2024¹, and the deadline was extended another three weeks to 11:59 on 27 March 2024¹. The government response to that consultation was added on 24 March 2026¹.

On commencement, the published dates differ, and the difference is worth stating rather than smoothing over. The consultation said the standards would come into force from 2025¹. The planning portal timeline records 2025 as the year the Future Homes Standard comes into force, with all new build homes required to be carbon zero ready, and 2024 as the year the standard would be published with related legislation implemented⁷. The government's 2022 position was that the standard would be brought into force in 2025². A later independent report describes the standard as coming into effect December 2026, described there as a planning assumption⁸. The government news release places implementation in early 2026³.

The honest reading is that the standard has been repeatedly restated and the operative date has moved. The consultation response was published in March 2026¹, and the implementing instrument is the Building Regulations etc. (Amendment) (England) Regulations 2026⁵. A householder or a buyer should treat any single date as provisional and check the current position for the specific development.

Separately, revised building regulations preventing new homes being connected to the gas grid are set to be implemented from 2027¹. That is a different instrument from the heating standard, and it addresses the connection rather than the appliance.

What a new home must have: heat pumps, solar and fabric standards

Three elements define a compliant new home, and they are not equally demanding.

Heating. Heat pumps become the primary heating technology¹. The standard will ensure new build homes are future-proofed with low carbon heating². The 2021 position was that the performance standard would be set at a level meaning new homes will not be built with fossil fuel heating such as a natural gas boiler¹.

Solar. Solar panels are required as standard on new homes³. The detail sits in the consultation response: the exception to the general approach is solar, which is handled differently⁴. One option considered would have required solar PV panels covering the equivalent of 40% of a new home's ground floor area¹. That option is described as an option, not as the adopted rule, so the exact coverage requirement should be read from the final regulations rather than from the consultation.

Fabric. The proposed new standard does not currently require an uplift to insulation requirements compared to existing standards¹. This is the element most often assumed and least supported. A new home under the standard is not, on the published evidence, a much better insulated home than one built to current rules; it is a differently heated one.

For energy independence, the combination is meaningful but partial. A heat pump removes gas from the heating load. Solar reduces the electricity drawn from the grid in daylight hours. Neither removes the connection to the grid, and without storage the solar output is exported or used immediately rather than banked for the evening.

Why gas boilers, hybrids and hydrogen-ready boilers do not qualify

The exclusion is explicit and covers the technologies households most often ask about. Gas boilers, including hybrid and hydrogen-ready boilers, will not meet the proposed standards¹. Fossil fuel heating will not meet the standard, including hydrogen-ready and hybrid boilers¹.

That closes off three routes at once. A conventional gas boiler fails on emissions. A hybrid, which pairs a heat pump with a gas boiler for peak demand, fails because the gas boiler is still fossil fuel heating. A hydrogen-ready boiler fails because it is a gas boiler at the point of installation, whatever it can be converted to later. The consultation language does not distinguish between them.

Biofuel systems are also unlikely to be permitted. The standards proposed are unlikely to allow the installation of biofuel systems, including wood and manufactured solid fuels¹. That is a consultation position rather than a settled rule, and it is stated as unlikely rather than prohibited.

There is a related point about grants that catches new-build buyers. New-build homes and social housing are not eligible for the Boiler Upgrade Scheme⁹, and the scheme guidance confirms that new builds by commercial property developers are not eligible at the point of being built, with eligible self-builds the only eligible new builds¹⁰. Social housing is not eligible¹¹. So a household moving into a new home cannot look to the Boiler Upgrade Scheme to fund a later change of heating system. The Warm Homes: Local Grant is also closed to gas and oil boilers, which are not eligible improvements under that scheme¹².

Exemptions and higher-risk buildings

The standard is not applied uniformly to every building type, and the exemptions are specific.

For blocks of flats, one option considered would not require solar PV panels for blocks of flats over 15 storeys¹. That is a height threshold, and it is described as an option rather than as the final rule. The solar requirement is the element most likely to be varied by building type, because the consultation response states that solar is handled differently from the rest of the standard⁴.

Higher-risk buildings carry their own regulatory regime, and the published material on the Future Homes and Buildings Standards does not set out a separate heating exemption for them. What the documents do show is that the standards are implemented through the Building Regulations, which already contain the higher-risk building provisions, so the interaction is a matter for the regulations rather than for the standard itself.

The practical position for a householder is that exemptions exist mainly for practical constraints: roof area, building height, and the feasibility of fitting the required technology. They are not exemptions from the direction of travel. A flat above 15 storeys may not carry solar panels, but it is still a new building under a regime that does not permit fossil fuel heating as the mains system in Scotland⁴ and that gas boilers will not meet in England¹.

What it means for existing homeowners

The single most important point is that the standard does not reach existing homes. It governs new build. Nothing in the Future Homes Standard requires a householder in an older property to replace a working gas boiler, and the 2021 statement of intent was about the performance standard for new homes, not retrofit¹.

What does reach existing homes is a separate and slower set of proposals. The Scottish Government has proposed a new Heat in Buildings Bill to require homeowners in Scotland to meet a minimum energy efficiency standard by 2033¹. The New Build Heat Standard consultation described similar requirements in existing buildings from 2025 onwards as the direction of travel¹³. The Heat in Buildings Strategy sets a target for over 1 million homes in Scotland to convert to zero emissions heating by 2030, and the equivalent of 50,000 non-domestic buildings⁷.

For England, the parliamentary briefing places the update to new home requirements in England and Wales in 2025, Scotland in 2024 and Northern Ireland in 2026 or 2027¹. The 2035 date that circulates for gas boiler phase-out is a strategy ambition rather than a regulation, and no legally binding decision has been made on it.

The independence picture for an existing household is therefore unchanged by this standard. A home on gas remains on gas, dependent on the grid for electricity and on a supplier for both. What changes is the resale and comparison landscape: as new homes come to market without gas heating, the running cost and comfort comparison between an older gas home and a new heat pump home becomes a live question for anyone buying. The site's guide to home heating running costs by fuel sets out how those costs compare, and heat pumps compared with boilers covers the technology difference directly.

Scotland's New Build Heat Standard and the Heat in Buildings Strategy

Scotland is the part of the UK where this is already settled law rather than a proposal. The New Build Heat Standard is a requirement set out in law and comes into force from 1 April 2024⁴. All new buildings applying for a building warrant from April 2024 need to install clean heating systems, and it also applies to some conversions⁴. Fossil fuel gas and oil boilers cannot be used as a mains heating system in new-build homes and buildings⁴.

The regulations were laid in the Scottish Parliament in the week commencing 5 June 2023, and the building standards Technical Handbooks were to be updated later in 2023¹³. The standard opened on 1 April 2024¹³. The Scottish Government administers it, and the published contact address is 2024heatstandard@gov.scot⁴. The Heat in Buildings Regulations Unit is named in the consultation material¹³.

Behind the new-build rule sits the Heat in Buildings Strategy, which is broader and slower. It sets a target for over 1 million homes in Scotland to convert to zero emissions heating by 2030, and the equivalent of 50,000 non-domestic buildings⁷. Emissions from heat in buildings will have to fall by 68% by 2030 compared with 2020⁷. On energy efficiency, the target for homes is at least equivalent to an EPC Band C, with all homes meeting at least this standard by 2033⁷. A new Heat in Buildings Strategy and Delivery Plan is due by the end of 2026¹⁴.

The funding attached to the strategy is £1.8 billion to 2026⁴. The Scottish Government has also assessed the employment effect: research suggests the additional jobs supported in 2030 will exceed those displaced by an estimated 16,400 as a result of investment in zero emissions heat jobs¹⁵.

For a Scottish household, the independence effect is the clearest in the UK. A new home has no gas heating connection to depend on, and its heat comes from electricity. The dependence that remains is on the grid, the supplier and the tariff, plus whatever the heat pump's own controls and any app require. The site's boiler and heating grants in Scotland page covers the support that exists for existing homes rather than new ones.

Expected savings and emissions reductions

The emissions figures are the most consistent numbers in the whole subject. An average semi-detached home under the standard will have 75% lower emissions than under 2013 standards¹. The government has stated 75% to 80% lower emissions than homes built to then-current Building Regulations², and at least 75% lower CO2 emissions than one built to current energy efficiency requirements¹. The standard's stated purpose is to improve energy efficiency and reduce carbon emissions so that new dwellings and non-domestic buildings are zero carbon ready⁵.

The bill savings are less settled, and the two figures in circulation measure different things. A parliamentary briefing cites MCS and Solar Energy UK saying the Future Homes Standard would save the average household around £1,000 a year¹. A separate independent report gives a saving of around £530 a year, based on a 3.5kW south facing installation⁸. The second is tied to a specific solar installation size and orientation; the first is a household average. They are not directly comparable, and neither should be read as a guaranteed figure for a particular home.

What drives the saving is the combination of a heat pump running on electricity instead of a gas boiler, and solar generation reducing imported electricity. What limits it is the same thing that limits independence: without storage, solar output is not available in the evening, and the heat pump's running cost depends on the electricity tariff and the flow temperature it is set to. The site's boiler flow temperature page explains why that setting matters for running cost, and solar thermal water heating covers the separate solar hot water route.
