Find out how the new AD L will impact your upcoming developments AD L White Paper

SAP 10 Analysis

Approved Document AD L is changing. Sites registered after June 2022 will need to meet new, stricter targets which are set to reshape the way we design and build our homes. This R&D service helps construction companies prepare for what’s to come by testing their current specification against the proposed new targets.

How Energist can help

The UK has committed to reaching net zero carbon standard by 2050. All sectors of industry need to play their part, and construction is no exception.

Building Regulations will soon be changing to enforce much stricter energy and emission targets on all new houses.

Thicker wall insulation, triple glazing, waste water heat recovery, heat pumps and solar panels are all items that construction companies will need to consider as standard in preparation for these changes.

The first wave of changes will happen in June 2022 when newly registered sites in England and Wales will need to meet the latest requirements. Un-started buildings on existing construction sites will need to fall in line from June 2023. Then, in 2025, a second update to Approved Document L will mean new homes need to be built even closer to a zero energy standard.

Similarly, Section 6 regulations in Scotland are expected to change in 2023.

Energist is known for taking a proactive stance on dealing with new regulations. We are offering in-depth analysis and advice to clients who want to plan ahead and be ready to build on the first day of the new regulations going live.

Our SAP10 Analysis will show how your current specification is likely to fare against the new targets, with options to show how to fully comply with the expected new standards.

This service is available to cover the 2022 / 2023 updates scheduled for England, Wales and Scotland.

Note: This analysis can only be used for development purposes at this time. For AD L compliance you will need to continue using our standard SAP service. Building control bodies will not accept SAP10 analysis as a form of compliance against the current (SAP2012) standard.
