On 1st October 2019 Government’s MHCLG published The Future Homes Standard consultation. iATS communicated it’s publication and summarised the changes for air tightness testers which was published as a news item on the 2nd October. Our sister company, Elmhurst Energy, then embarked on a countrywide tour of briefing events which culminated in the Elmhurst Building Regulations Conference on the 10th December. At each event they explained the context of the changes, details of the proposal and the practical implications, before discussing our own views on the changes and seeking the input from members.

Key messages

Having listened to member’s views iATS has now published our ‘final’ consultation response to Chapter 5 Airtightness. Our key messages are:

  1. SAP must be maintained as close to the truth as possible. Corrupting air tightness results to influence the design should be avoided.
  2. All new homes should be subject to an airtightness test.
  3. Pulse should be introduced as an alternative method of testing buildings, even those below 1.5 m3/m2/h.
  4. An independent approved airtightness testing methodology should be adopted.

Comment from Scheme coordinator

iATS Scheme Coordinator, Jennifer Hartley, states; “Since the Future Homes Consultation was published last year we have liaised with our members to develop our consultation response. We believe the proposals in the consultation will bring an exciting future for the air tightness testing industry and look forward to publication of the new regulations later in the year.”

Expected adoption of results

It is expected that the results of the consultation will appear in legislation in the spring, for adoption in the autumn of 2020.

Consultation on changes to Part L for existing dwellings, overheating and commercial buildings in England is expected within the next few weeks. Changes to building regulations in Scotland, Northern Ireland and Wales are also planned.
