The Future Homes Standard 2026 bans gas boilers in all new UK homes from this year
If you are planning to build a new home in 2026, the rules have changed fundamentally. From this year, every new house in England (and devolved nations with aligned timelines) must be built without a gas boiler as its primary heating source. The Future Homes Standard is a building regulation, not a grant or a voluntary scheme, and it applies only to new constructions.
The Future Homes Standard 2026 bans gas boilers in all new UK homes, requiring low-carbon heating instead. Build costs rise by £4,500-£6,000 per home, but annual energy savings of £200-£350 offset this over time. Check your build plans with a certified installer.
- Gas boilers banned in all new UK homes from 2026.
- New homes must cut carbon emissions by 75-80% vs 2013 rules.
- Heat pumps, heat networks, or electric heating are mandatory.
- Average build cost increase of £4,500-£6,000 per new home.
- Annual energy bill savings of £200-£350 for occupants.

The standard mandates that new homes produce 75-80% fewer carbon emissions compared to those built under 2013 regulations (DESNZ, 2026). The primary heating system must be a low-carbon technology such as a heat pump, a heat network, or direct electric heating. No fossil fuel boiler option is permitted. Existing homeowners are not affected by this regulation unless they are building a new property.
What the Future Homes Standard actually costs to build into a new home
The government’s own impact assessment estimated the average additional build cost per new home at £4,500-£6,000 to meet the standard (DESNZ, 2023). This figure covers improved fabric efficiency, such as better U-values for walls, windows, and roofs, plus the installation of a heat pump or connection to a heat network. The cost does not include land or external works. It is purely the incremental cost over a home built to 2013 regulations.
For a typical three-bedroom semi-detached house, the additional build cost is at the lower end of that range if standard heat pump models are used. Larger or more complex homes may push costs toward the upper end. Builders typically pass these costs into the final sale price, so buyers of new homes will see them reflected in the purchase price.
How much the standard saves you on annual energy bills
The Energy Saving Trust estimates a new Future Homes Standard home saves the occupant £200-£350 per year on heating bills compared to a gas-boiler home built to 2013 standards (Energy Saving Trust, 2025). This estimate is based on a typical three-bedroom semi-detached house using an air-source heat pump with high fabric efficiency. Actual savings vary by property size, local climate, and energy tariff. The EST provides a general range, not a guarantee for every home.
For example, a well-insulated new home with triple glazing and a modern heat pump will use significantly less energy than an older home with a gas boiler. However, if electricity prices remain higher than gas per kWh, the cash savings may be smaller than the carbon savings. The standard is designed primarily to cut emissions, not necessarily to cut bills in every scenario.

The direct answer to “What is the Future Homes Standard?”
The Future Homes Standard is a UK building regulation, effective from 2026, that requires all new homes to be built without fossil fuel heating, using low-carbon technology and high fabric efficiency to cut carbon emissions by 75-80% compared to 2013 standards (GOV.UK, 2026). It applies to new-build homes only, not retrofits or existing homes. The standard does not ban gas boilers in existing homes but makes them illegal in new constructions. Key technologies include heat pumps, heat networks, solar PV (optional but common), and triple glazing.
How to verify a new home meets the Future Homes Standard (MCS, SAP, and certification)
Builders must produce a Standard Assessment Procedure (SAP) calculation for each new home, showing it meets the carbon and energy targets (GOV.UK, 2026). Heat pumps installed must be MCS-certified (Microgeneration Certification Scheme) to ensure performance and eligibility for any associated incentives (MCS, 2026). The home must pass a final Building Regulations compliance check by the local authority or an approved inspector. Homebuyers should request the SAP certificate and MCS documentation from the developer before completion. Without these documents, you cannot be sure the home complies with the standard.
If you are buying a new home, ask specifically for the SAP rating and the heat pump’s MCS certificate. These documents confirm that the home meets the required efficiency and carbon targets. What to check when buying a new build home
What the standard means for homeowners who are not building new homes
The Future Homes Standard does not require existing homeowners to replace their gas boilers or upgrade insulation. It signals a future shift in the housing stock, but no retrofitting mandate exists for existing homes under this regulation (DESNZ, 2026). The standard may indirectly increase the value of new-build homes with lower running costs, but no data on resale value uplift is yet available. Homeowners considering a future heat pump retrofit should note that the standard sets a benchmark for efficiency, but grants such as the Boiler Upgrade Scheme remain separate for existing homes (GOV.UK, 2026).

Frequently Asked Questions
The Future Homes Standard 2026 is a building regulation requiring all new homes in England to produce 75-80% fewer carbon emissions than those built to 2013 standards. It bans gas boilers as the primary heating source and mandates low-carbon technologies like heat pumps. This regulation is enforced by the government's Department for Energy Security and Net Zero (DESNZ).
No, the Future Homes Standard applies only to new constructions, not existing homes. Existing homeowners are not required to replace their gas boilers or upgrade their heating systems under this regulation. If you are renovating or extending an existing property, the standard does not apply unless you are building a completely new house.
The average additional build cost to meet the Future Homes Standard is £4,500-£6,000 per new home, according to the government's impact assessment (DESNZ, 2023). This covers improved insulation and a heat pump or heat network. Builders typically pass this cost into the sale price, so buyers pay it upfront.
A new Future Homes Standard home saves the occupant £200-£350 per year on heating bills compared to a gas-boiler home built to 2013 standards (Energy Saving Trust, 2025). Savings depend on house size and heat pump efficiency. Over 10 years, this totals £2,000-£3,500.
The Future Homes Standard permits low-carbon heating systems such as air source heat pumps, ground source heat pumps, heat networks, and direct electric heating. Gas boilers, oil boilers, and LPG boilers are banned. The system must be the primary heating source for the new home.
