New Build's

At Retro Sure Services, we support developers, principal contractors, and housing providers in meeting the UK’s increasingly stringent energy efficiency and sustainability standards for new homes.

With the Future Homes Standard fully in force from 2026, new builds must achieve at least 75–80% lower carbon emissions compared to 2019 levels through enhanced fabric performance, low-carbon heating (like air source heat pumps), solar PV integration, and airtight construction. Compliance with updated Part L Building Regulations, SAP (now transitioning to the Home Energy Model), and on-construction requirements has never been more critical to avoid delays, secure approvals, and future-proof properties.

Our in house team of accredited On Construction Domestic Energy Assessors and air tightness specialists delivers:

SAP assessments and on-construction EPCs
Air tightness testing (blower door and Pulse methods) for compliance verification
Technical assessments and fabric performance checks
Energy modelling and improvement advice to optimise designs

Section Title

In today’s new build sector, meeting the Future Homes Standard, achieving Part L compliance, and delivering high-quality homes on time requires precision, reliability, and deep regulatory knowledge. Retro Sure Services is the partner many developers and contractors rely on to navigate these demands effectively.

All our work is delivered by a fully in-house team of accredited professionals, no subcontractors, ensuring consistent standards, direct accountability, and seamless communication throughout the project. Our assessors and engineers bring extensive experience in new build compliance, understanding exactly what Building Control requires, how to meet SAP/HEM targets on site, and how to achieve airtightness without triggering costly rework or programme delays.

We conduct thorough blower door and Pulse air tightness testing, detailed snagging inspections, and precise SAP assessments, identifying potential issues early from minor sealing gaps to finishing defects so they can be resolved before handover. Our reports are clear, practical, and action-oriented, supported by photographic evidence and straightforward recommendations that enable your team to respond efficiently.

Above all, we are committed to outcomes that go beyond compliance: homes that perform efficiently, feel comfortable from day one, and reflect positively on your brand. Fewer post-occupancy issues, stronger buyer satisfaction, and a smoother handover process are the results we consistently help deliver.
