If you’ve heard that gas boilers are being “banned,” it’s worth knowing exactly what’s changing, when, and who it actually affects. The rules in question come from the Future Homes Standard (FHS), a major update to Building Regulations that reshapes how new homes in England are heated. Here’s what it means in practice, and why it matters even if you’re not building a new house.
What Is the Future Homes Standard?
The Future Homes Standard is the 2026 update to Part L of the Building Regulations, the section covering conservation of fuel and power. It requires new homes to produce at least 75% lower carbon emissions than homes built to 2013 standards, a target so demanding that no fossil fuel heating system can realistically meet it. In effect, this means heat pumps, solar PV, and significantly improved building fabric become the default for new-build housing in England.
Key Dates to Know
The Approved Documents setting out the detailed technical requirements were published in March 2026, with the standard itself coming into force on 24 March 2027. A 12-month transitional period then runs until 24 March 2028, during which developers who submitted planning applications before March 2027 can still build to the older Part L 2021 standard, provided work begins within that window. After the transition ends, all new homes must meet the full FHS requirements.
What This Means for Heating Systems
Gas boilers simply won’t meet the FHS carbon targets, and that includes hybrid systems and hydrogen-ready boilers, neither of which currently qualify as compliant. Air source heat pumps are expected to become the default heating choice for new-build homes, since they can deliver the necessary efficiency without relying on fossil fuels.
Alongside heating, the FHS introduces a new requirement (known as Requirement L3) making on-site renewable electricity generation a functional part of Building Regulations. In practice, this means developers must fit solar PV equivalent to around 40% of a home’s ground floor area where feasible, pairing every new heat pump with a meaningful amount of solar generation to offset its electricity use.
Does This Affect Existing Homes?
No. The Future Homes Standard applies only to new-build properties in England. If you already own a home with a gas boiler, you remain free to repair, service, or even replace it like-for-like; nothing in this legislation requires existing households to switch to a heat pump. That said, the direction of travel is clear, and many homeowners are choosing to make the switch ahead of any future changes, particularly with the Boiler Upgrade Scheme grant still available to help with costs.
What About Cost?
The government’s own Impact Assessment estimates the FHS will add around £4,350 to the cost of building each new home, driven largely by heat pumps, solar PV, and enhanced insulation. While FHS-compliant homes won’t pay a gas standing charge and benefit from much better insulation, the assessment notes that overall bill savings compared with a Part L 2021 new build may be fairly marginal in the short term, since electricity currently costs roughly four times more per unit than gas. That gap is expected to narrow as heat pump supply chains mature and electricity pricing evolves.
What This Means for You
If you’re buying a new-build home, you can expect it to be heated by an air source heat pump and supported by solar PV from the outset, with noticeably better insulation than older housing stock. If you’re self-building, renovating, or simply planning ahead for your existing home, it’s worth understanding how these systems work together, since heat pump and solar PV installations will likely become more familiar, more available, and increasingly cost-competitive in the years ahead.
NCS and the Move Towards Low-Carbon Heating
At NCS, we already install and maintain air source heat pumps and solar PV systems across Hertfordshire and the South East, giving us first-hand experience of exactly the technologies the Future Homes Standard is built around. Whether you’re planning a self-build, considering a renovation, or simply curious about your options ahead of any future changes to existing homes, our team can talk you through what a heat pump and solar PV setup would look like for your property.
