Future Homes Standard: What UK Homebuilders Need to Know Now It Has Been Published

Written by Kieran Fields (RTA Marketing Group Chairman)

The Future Homes Standard has now moved from policy expectation to published regulation. On 24 March 2026, the Government published the Future Homes and Buildings Standards, laid the statutory instrument needed to amend the Building Regulations, and issued new statutory guidance for Approved Document L and Approved Document F. For homebuilders, developers, roofing specifiers, and the wider construction supply chain, this creates a clear implementation timetable and removes much of the uncertainty surrounding earlier consultation-stage guidance.

The new standards are intended to ensure that new homes in England are built with low-carbon heating, high levels of energy efficiency, and the ability to become zero-carbon in use as the electricity grid decarbonises. The Government has stated that the Future Homes Standard will ensure new homes emit, on average, at least 75% less carbon than homes built to 2013 standards. This is a decisive step in the evolution of Part L and Part F, and it will reshape design, specification, commissioning, handover and aftercare across residential development.

For the pitched roofing sector, the implications are especially significant. Roofs will continue to play a core role in thermal performance, airtightness, condensation risk management and long-term durability. They will also become even more central to building services strategy because the updated Building Regulations introduce a new functional requirement for on-site renewable electricity generation for new dwellings and buildings containing dwellings. In practical terms, this means that roof design, roof loading, orientation, integration of solar PV, ventilation detailing, and coordination with the whole-building energy strategy must be considered from the earliest design stages.

What has changed now that the Future Homes Standard has been published?

The most important update is that the Future Homes Standard is no longer a proposed policy. It is now part of a confirmed regulatory pathway. The Building Regulations etc. (Amendment) (England) Regulations 2026 come into force on 24 March 2027 for most non-higher-risk building work, with separate provisions for higher-risk building work and work to existing higher-risk buildings coming into force on 24 September 2027, subject to transitional arrangements.

This timetable means that businesses now have a fixed window in which to finalise specifications, build supply chain capability and prepare construction teams for delivery. The standard should no longer be treated as a distant compliance issue. It is an immediate priority for design, procurement, and quality management.

Low-carbon heating, solar PV and the role of the building fabric

The new standards are designed around homes that do not rely on fossil-fuel heating as the normal route to compliance. While the regulatory approach does not need to be described as a simple blanket ban on gas boilers, the performance targets make low-carbon heating systems, particularly heat pumps and low-carbon heat networks, the practical direction of travel for most new homes. The Government has also confirmed that solar panels will be installed in the majority of new homes, with flexibility where solar is not suitable or feasible, including some higher-risk buildings and constrained sites.

This has direct implications for the roof. A pitched roof is not simply a weathering layer; it is part of the building envelope, a platform for renewable electricity generation and a key interface between fabric performance and building services. Under the Future Homes Standard, design teams will need to consider solar PV integration alongside roof pitch, orientation, shading, structural loading, tile compatibility, underlay performance, ventilation and fire safety requirements. Decisions made late in the process are likely to increase cost and risk.

At the same time, improved energy performance places greater emphasis on insulation continuity, reduced thermal bridging, and airtightness. The updated guidance also strengthens the focus on commissioning, installation quality, competent persons schemes, heat pump controls, mechanical ventilation and homeowner operating information. The lesson for roofing specification is clear: products and systems must be selected as part of a coordinated whole-building performance strategy, not in isolation.

Seven essentials for Future Homes Standard delivery

The previously identified “FHS Essentials” remain useful, but they should now be treated as delivery disciplines for a published standard rather than early preparation steps. The implementation period is short, and organisations that wait until formal commencement dates risk discovering design, procurement or grid constraints too late.

Lead early, learn fast: Use live schemes, pilots and prototypes to test FHS-compliant specifications before the 2027 implementation date.

Prioritise grid availability: Engage electricity network operators early, especially where heat pumps, solar PV, EV charging and all-electric homes increase site demand.

Own the customer journey: Prepare buyers for heat pumps, ventilation systems, solar PV and new patterns of home operation, supported by clear Home User Guides.

Evolve your design: Review house types, roof forms, PV layouts, service routes, plant locations and airtightness details before planning and procurement decisions are locked in.

Commission with care: Verify heat pumps, ventilation, PV and controls before handover, using competent installers and robust quality assurance.

Build as designed: Maintain strict site discipline, because low-carbon homes are less forgiving of thermal bypass, air leakage, poor junction detailing or unapproved substitutions.

Get heating design right: Treat heat-loss calculations, emitter sizing, flow temperatures, controls and user guidance as mission-critical design tasks.

Pitched roofing plays a central role in Future Homes Standard compliance because the roof now must support multiple performance outcomes simultaneously. It must continue to provide long-term weather protection and durability while also contributing to thermal efficiency, airtightness strategy, moisture management and renewable electricity generation.

The introduction of functional requirement L3 for on-site renewable electricity generation is particularly important. In many house types, the pitched roof will be the most logical location for solar PV. This increases the need for early coordination between architects, energy assessors, roofing manufacturers, structural engineers, PV installers and site teams. The roof design must accommodate PV without compromising tile performance, roof ventilation, detailing, maintenance access, or the long-term integrity of the roofing system.

Future Homes Standard roofing specification should therefore consider the whole roof build-up. This includes roof tile selection, fixing specification, underlay and batten compatibility, ventilation strategy, insulation continuity, fire performance, weather exposure, PV mounting method and workmanship on site. It also means engaging manufacturers early to ensure the chosen pitched roofing system is compatible with the intended PV solution and the broader compliance model.

For homebuilders, this creates both a challenge and an opportunity. Those who treat the roof as a strategic performance element will be better placed to deliver homes that comply, perform as designed and satisfy customers. Those who leave roof and PV coordination until late design or construction stages are more likely to face redesign, programme delays, installation compromises or avoidable remedial work.

Handover and homeowner confidence

One of the most important changes in the published standards is the emphasis on information for homeowners. The new regulation 40C requires information to be provided to homeowners of new dwellings in an appropriate format, and the updated statutory guidance includes Home User Guide provisions. This matters because low-carbon homes are operated differently from traditional gas-heated homes.

Homeowners will need to understand how to use heat pumps, ventilation systems, heating controls and solar PV effectively. If they do not, the risk is not only higher energy use or lower comfort; it is reputational damage for the developer and reduced confidence in low-carbon homes. For the construction supply chain, this reinforces the importance of commissioning, clear documentation and practical aftercare.

Acting now on a published standard

The Future Homes Standard is no longer simply “coming”. It has been published, the regulatory pathway is defined, and the transition period is now measurable. For homebuilders, the period before 24 March 2027 should be used to finalise compliant specifications, test delivery assumptions, strengthen quality control and engage supply chain partners.

For roofing specifiers, this means early consideration of pitched roof design, solar PV integration, insulation continuity, airtightness and installation quality. The roof will be a key part of delivering the Future Homes Standard in practice, and engaging with RTA members and technical guidance at the outset can help reduce risk.
