Part L Consultation
Future Homes Part L Consultation
The government issued its proposed Future Homes Standard for consultation in October 2018. The consultation terminates on 7th February 2020. LETI has prepared a response to the consultation, which includes:
Key messaging document (downloadable .pdf)
Explanatory document - Part L is Broken (downloadable .pdf)
Template of proposed answers to the consultation’s questions (downloadable Word Document)
Letter to your MP template (downloadable Word Document)
Suggested social media wording for Twitter, LinkedIn and Facebook (downloadable Word Document)
Press release wording for contacting others (downloadable Word Document)
We have three key strategies to promote our response, encourage others to respond, and put pressure on the government to take our concerns seriously:
1. Get as many people and organisations to respond as possible by:
b. Submitting a full response by either:
i. Copying and pasting LETI’s proposed answers and submitting them here:
Note: LETI's proposed answers provide a template response for every question. Use this to formulate your own answers - unique answers with similar themes will have the greatest impact.
ii. Create a PDF of the LETI’s proposed answers and rebadge it as your own. Email them to:
2. Get the media (industry and general) talking about the Future Homes Standard by notifying them (by using our press release guidance) or through social media (suggested wording here and images here).
3. Get MPs talking about the Future Homes Standard by writing an email to your MP
Future Homes Part L Consultation: Key Messaging
LETI believes that by 2030 all new buildings will need to operate at Net Zero (i.e. annual net zero carbon emissions), which means that by 2025 100% of all new buildings must be designed to Net Zero.
To achieve this we need a clear plan as to how we will measure compliance with this target at design stage in a way that informs good design. To ensure ALL new buildings meet Net Zero Carbon, Approved Document Part L needs to become the legislative driver for this. We have developed a Key Messaging Document in response.
Over 607 signatories have signed to support the key messaging, including more than 141 organisations, representing a diverse range of different disciplines within the construction industry.

Problems with the proposed consultation
Key issues with the proposed consultation:
1. Fabric performance is likely to get worse. A home in 2020 could be less insulated than a home under 2013 Building Regulations. The use of an energy efficient heating system has the ability to mask fabric performance.
2. Carbon and primary energy factors disguise the energy efficiency of a home. The energy consumption of a home can be high but carbon emissions low. This leads to inefficient homes which appear to be performing well.
3. Local authorities will lose the ability to meet their climate emergency zero carbon commitments if they are stripped of their powers to go above and beyond the new Part L
Part L is broken - help us fix it
We have produced a summary document explaining key aspects of how Part L works and why the proposed changes are problematic. This includes a description of how the Standard Assessment Procedure (SAP) works, why the proposed changes means that fabric performance is likely to get worse and how the currently proposed metrics do not mandate low energy design.
This document is broken down into the following four pages:
How energy calculations work
Fabric performance is likely to get worse
Carbon and Primary energy metrics do not result in low energy homes
Local Authorities will be stripped of the ability to set local targets
