The Future Homes Standard: What Every Housebuilder and Installer Must Know
The most significant overhaul of UK building regulations in a generation is now law. Here’s everything you need to prepare for March 2027 and why acting now is your competitive advantage.
After years of consultation and industry lobbying, the UK government has laid The Building Regulations 2026 in parliament. This is not incremental tinkering; it is a wholesale transformation of what a new home must be. For housebuilders and installers, the message is clear: the time to prepare is now, not in 2027.
Key Dates and Transition Rules
24th March 2026 – Government publishes final Approved Documents for the Future Homes Standard. The regulations are laid in parliament.
24th March 2027 – Regulations come into force for all new residential buildings (standard risk). Projects with a building notice or full plans application submitted before this date may proceed under current Part L 2021 standards provided construction commences before March 2028.
24th September 2027 – Regulations come into force for higher-risk buildings (18m+ in height containing dwellings).
24th March 2028 – End of 12 month transitional period. All new construction must fully comply. Earlier transitional provisions from 2013 and 2021 (which still allowed some sites to build to 2010 standards) are now permanently revoked.
Any plots relying on older 2013 or 2021 transitional provisions must now meet the Future Homes Standard if not yet commenced.
Part L: Energy and Carbon Emissions
Approved Document L has been renamed from ‘Conservation of Fuel and Power’ to ‘Energy and Greenhouse Gas Emissions’, a signal of how fundamentally the framework has shifted. The headline requirement is that new homes must emit at least 75 – 80% fewer carbon emissions than homes built under 2013 standards.
CRITICAL CHANGE
Solar PV is now a functional requirement
Every new home must have on-site renewable electricity generation available to residents. In the vast majority of cases, this means solar panels equivalent to 40% of the ground floor area. Solar Energy UK estimates this will apply to approximately 90% of new homes in England. Exemptions exist only where installation would make no meaningful contribution, and for high-rise buildings (18m+).
Gas boilers are banned in new builds
No new home may be built with a gas boiler as its primary heating source. Air-source and ground-source heat pumps, district heating and other low-carbon alternatives become the standard. Homes should be built ‘net zero ready’, meaning they won’t need additional retrofitting as the energy grid becomes fully decarbonised.
For non-domestic buildings, the solar requirement is equivalent to 40% of the foundation area, with exceptions for low electricity consumption buildings and high-rise structures.
Part F: Ventilation
As homes become significantly more airtight to meet the new fabric standards, ventilation becomes more important, not less. Approved Document F has been updated alongside Part L to reflect this reality.
Commissioning by a competent person scheme member
All new ventilation systems must be commissioned by a member of a competent person scheme. Vane anemometers are banned for flow measurement; powered flow hoods are now required. For builders, this means investing in the right equipment and ensuring installers hold the appropriate scheme registration.
UPDATED GUIDANCE
Occupant handover documentation required
A practical guide explaining how ventilation, heating and on-site generation systems work in everyday language must be provided to the occupant in both digital and physical formats. This marks a shift from purely technical sign-off to genuine occupant usability and creates a compliance trail housebuilders must manage.
Mechanical ventilation rates uplifted
The minimum ventilation supply rate for mechanical systems is set at 30 litres per second per person. Background ventilation must meet a minimum of 5,000mm² equivalent per room. Where continuous mechanical extract ventilation (MEV) is used, background trickle vents of at least 4,000mm² per habitable room are required alongside it.
Part O and Part S: Overheating and EV Charging
Part O: Overheating mitigation
In force since June 2022 and continuing under the FHS framework, Part O requires that overheating risks are identified and mitigated at design stage, not corrected post-construction with cooling equipment. England is split into ‘moderate’ and ‘high risk’ zones, with stricter glazing and cross-ventilation requirements in urban and suburban areas most at risk.
Part S: EV charging points
Every new dwelling with a driveway or associated parking must have a fully functional, smart-enabled EV charger capable of responding to time-of-use tariffs. When combined with solar generation and battery storage, this creates the foundation for a complete home energy ecosystem.
Battery Storage: The Next Frontier
Battery storage was not mandated under the final Future Homes Standard, housebuilders lobbied successfully against the upfront cost. However, industry voices are clear: it is only a matter of time. In the meantime, the regulations strongly encourage homes to be ‘battery ready,’ with cable routes and consumer unit space sized to make future battery installation quick and cheap.
The new PAS 63100:2024 standard introduces guidance for battery installations: batteries should be located away from escape routes and sleeping areas, fire-resistant enclosures are required in many cases, and clear requirements for ventilation, isolation switches, and emergency shutdowns now apply.
Our Supply Partnerships: GSE Integration & Sunsynk
Meeting the Future Homes Standard at scale demands a reliable, quality-assured supply chain. We have established direct supply partnerships with two of the most respected names in the industry, specifically to serve housebuilders and installers navigating these new requirements.
GSE is one of Europe’s leading manufacturers of roof integration systems for solar PV. Their in-roof mounting systems are designed for new build environments, offering clean aesthetics, weathertight performance and the flexibility needed to meet the 40% coverage requirement across diverse roof designs and pitches. As a direct supply partner, we can support housebuilders with design, specification and volume procurement.
Sunsynk manufactures hybrid inverters and battery storage systems already installed in tens of thousands of UK homes. Their all-in-one hybrid inverters work hand in hand with solar PV and EV chargers, making them an ideal platform for the interconnected energy systems the Future Homes Standard encourages. As a direct Sunsynk partner, we supply inverters and batteries at competitive housebuilder rates, with technical training and system design support.
What Housebuilders and Installers Should Do Right Now
Audit your pipeline against March 2027
Any site without a building notice or full plans application submitted before 24 March 2027 must be designed to FHS standards. Start modelling under SAP 10.3 now, leaving this to late 2026 creates design and supply chain risk.
When 90% of new homes require solar PV, demand for panels, mounting systems and hybrid inverters will spike sharply. Housebuilders who establish supply agreements in 2026 will be far better positioned than those scrambling in 2027.
Register your ventilation installers with a competent person scheme
Ventilation commissioning by an unregistered installer will no longer satisfy building control. Identify which of your installers need scheme registration and begin the process well in advance of your first FHS compliant handover.
Plan for battery readiness from day one
Design cable routes and consumer units to accommodate battery storage from day one. It costs very little at build stage and significantly increases the home’s longevity and resale value, as well as positioning your development ahead of any future regulatory change.
Ensure MCS certification for every installation
The government and industry bodies are clear: solar installations in new build homes should be delivered by MCS certified installers to MCS standards. Buyers, mortgage lenders and building control will increasingly require this as a baseline.
