What to prioritise this quarter
Forty-plus regulatory items in flight; only a handful actually move project decisions in the next 90 days. Here are the three to pay attention to now, with the action each role should take.
Future Homes Standard final guidance
Approved Documents L & F (2026) confirmed. Solar PV, low-carbon heating and tighter U-values mandatory for new homes from Dec 2026.
Action: lock in heat pump + PV supply chain. Build HEM modelling capacity now.
UK CBAM scoping window
Carbon Border Adjustment hits steel, aluminium and cement imports from Jan 2027. Reporting starts before that - pricing ahead of supply.
Action: audit imported material exposure. Lock in UK-route supply where possible.
Part Z whole-life carbon
Industry-backed proposal gaining Parliamentary support. Once mandated, large projects will need whole-life carbon assessments and reporting.
Action: start practising on current projects. Build the methodology before it’s required.

When
Part Z (Whole-Life Carbon) - Government Consultation
Government consultation on whole-life carbon reporting for large buildings launched. Industry-led Part Z proposal has gained significant Parliamentary support with cross-party backing.
Impact:
Major projects should begin whole-life carbon assessments now to prepare for mandatory requirements.
Building Safety Act - Principal Designer Registration Deadline
All Principal Designers and Principal Contractors for higher-risk buildings must be registered with the Building Safety Regulator (BSR).
Impact:
Failure to register means inability to work on HRBs. Check BSR registration status immediately.
UK Net Zero Carbon Building Standard (UKNZCBS) - Published
UKNZCBS published covering both embodied and operational emissions. Sets verified performance targets for new residential, commercial, and education buildings across energy use intensity, embodied carbon, and airtightness.
Impact:
Defines what 'net zero carbon' means for UK buildings. Voluntary but rapidly becoming market expectation for major developers.
FCA CP26/5 - Sustainability Disclosures Consultation (Closed)
The FCA consulted (30 January to 20 March 2026) on requiring listed issuers to disclose against the UK SRS, replacing current climate disclosure rules. A policy statement is expected in autumn 2026, with mandatory UK SRS S2 climate reporting for around 500 listed companies applying to accounting periods from 1 January 2027.
Impact:
Listed construction companies should prepare to disclose against UK SRS and build Scope 3 supply-chain data systems ahead of the expected 1 January 2027 start.
UK Sustainability Reporting Standards (UK SRS S1 & S2) - Final Standards Published
The Department for Business and Trade published the final UK Sustainability Reporting Standards (UK SRS S1 and S2) on 25 February 2026, based on the ISSB standards with six minor UK amendments. These provide the definitive basis for voluntary adoption ahead of expected mandatory requirements.
Impact:
Companies should align their sustainability reporting frameworks and Scope 3 data collection with the final UK SRS S1 and S2 standards now.
UK Sustainability Reporting Standards - Voluntary Adoption
UK SRS (based on ISSB standards) now available for voluntary adoption. Companies can begin reporting ahead of mandatory requirements expected in 2027.
Impact:
Early adopters gain competitive advantage with investors and clients. Scope 3 reporting preparation essential for supply chain.
Future Homes & Buildings Standards - Published
Government has laid the regulations for the Future Homes Standard and Future Buildings Standard via SI 2026/335 (The Building Regulations etc. (Amendment) (England) Regulations 2026), publishing updated Approved Documents L and F (2026). New homes must be built with solar panels, low-carbon heating (heat pumps/heat networks), and high fabric efficiency as standard, achieving at least 75% less carbon than 2013 standards. Compliance is initially demonstrated using SAP 10.3; the Home Energy Model (HEM) is not yet an approved methodology and is expected to follow later. Regulations come into force 24 March 2027 (24 September 2027 for higher-risk building work), subject to transitional provisions.
Impact:
Housebuilders must prepare supply chains for heat pumps, solar PV, and MVHR, and upskill for SAP 10.3 compliance now, with HEM adoption to follow.
Future Buildings Standard - Published
Published alongside the Future Homes Standard under SI 2026/335. Sets new energy performance requirements for non-domestic buildings including updated Parts L and F. Compliance is initially demonstrated using SAP 10.3 rather than the Home Energy Model. Regulations come into force 24 March 2027 (24 September 2027 for higher-risk building work), subject to transitional provisions.
Impact:
Commercial developers must prepare for updated compliance requirements using SAP 10.3, with new non-domestic buildings needing significantly higher energy performance.
UK SRS - Mandatory FCA Rules Expected
FCA expected to finalise mandatory sustainability reporting rules for large listed companies in autumn 2026, applying for accounting periods from January 2027. Scope 3 emissions reporting included.
Impact:
All major construction companies must prepare Scope 3 supply chain data. Material manufacturers will face data requests from clients.
UK CBAM - Importer Registration Opens
Importers of steel, aluminium, cement, ceramics, and fertiliser must register ahead of the UK Carbon Border Adjustment Mechanism launch in January 2027. A minimum registration threshold of £50,000 of relevant imports applies (raised from the originally proposed £10,000).
Impact:
Importers should assess whether they exceed the £50,000 threshold, understand the carbon content of their supply chain, and prepare reporting systems.
UK CBAM - Full Launch
UK Carbon Border Adjustment Mechanism launches. Carbon levy on imports of steel, aluminium, cement, ceramics, hydrogen, electricity, and glass. Based on actual or default emission values.
Impact:
Imported construction materials face carbon pricing. UK domestic manufacturers may gain competitive advantage. Material costs for imported steel/aluminium likely to rise.
Future Homes Standard - Transitional Arrangements
Transitional provisions under SI 2026/335 allowing approved plans to proceed under current Part L before full FHS takes effect. For transitional protection, notices must be submitted before 24 March 2027 and construction commenced within the transitional window (by around 24 March 2028). SME developers get no blanket exemption.
Impact:
Window closing for developers - submit building notices before 24 March 2027 and commence work by ~24 March 2028 to retain transitional protection.
UK SRS - First Mandatory Reports Due
First mandatory sustainability reports due from large listed companies for accounting periods starting January 2027. Scope 1, 2, and 3 emissions reporting required.
Impact:
Construction companies must have emissions data systems in place. Supply chain data requests will cascade to subcontractors and manufacturers.
EPC Rating C Minimum - Non-Domestic (Proposed)
Proposed MEES tightening requiring non-domestic rented buildings to achieve minimum EPC Rating C. Government consultation response still awaited - date may shift to 2028.
Impact:
Landlords must retrofit properties or face penalties. Major retrofit wave expected. Demand for energy consultancy and building services design to surge.
Biodiversity Net Gain - Small Sites Compliance
All developments including small sites must deliver minimum 10% biodiversity net gain, measured using the statutory biodiversity metric. Two-year transition period from February 2024 mandate for major sites.
Impact:
All developers must factor BNG costs and land requirements into project feasibility. Habitat banking market growing rapidly.
EPC Reform - New Energy Performance Metrics
EPCs move from a single headline rating to four metrics (energy cost, fabric performance, heating system, smart readiness) calculated with the Home Energy Model. Partial government response published 21 January 2026; launch was delayed in March 2026 from October 2026 to the second half of 2027, with the exact date due to be agreed by summer 2026.
Impact:
Landlords, developers and assessors should plan for the four-metric EPC regime and HEM-based assessments arriving during 2027.
Part Z - Mandatory Embodied Carbon Limits (Expected)
Expected introduction of mandatory whole-life carbon reporting and embodied carbon limits for buildings over 1,000m². Will require A1-A5 reporting at planning stage and whole-life (A-C) at completion.
Impact:
Material selection becomes carbon-critical. Low-carbon specification, design for disassembly, and material passports will become standard practice.
Future Homes Standard - Full Compliance Required
All new homes must meet the full Future Homes Standard after the transitional period ends (~24 March 2028, roughly 12 months after the regulations come into force on 24 March 2027 under SI 2026/335). Solar panels, low-carbon heating (heat pumps or heat networks), and high fabric efficiency mandatory. No new gas boilers. At least 75% less carbon emissions than 2013 standards. Compliance demonstrated via SAP 10.3 (HEM to follow later).
Impact:
Every new home must have solar, a heat pump, and meet stringent fabric standards; housebuilders must adapt supply chains and designs before the transitional tail ends around March 2028.
EPC Rating C - Domestic Rented Properties (Proposed)
Government response published 21 January 2026 confirming privately rented homes in England and Wales must meet the equivalent of EPC C by a single compliance date of 1 October 2030. A dual-metric standard applies (fabric performance first, then a heating-system or smart-readiness standard), with a raised cost cap of £10,000 and 10-year exemption validity. Legislation to follow, with a statutory instrument aimed to come into force in 2027.
Impact:
Landlords should plan retrofits now to meet EPC C by 1 October 2030, budgeting up to the £10,000 cost cap and prioritising fabric-first improvements.
