On 19th December 2019 Welsh Government published the Building Regulations Part F and L review consultation. Our sister company, Elmhurst Energy, then embarked on a tour of briefing events. 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 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 Part F and L 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 Wales is expected within the next few weeks. Changes to building regulations in Scotland and Northern Ireland are also planned for the near future.
