We conduct SAP calculations to assess the energy performance of residential buildings. Our accredited assessors ensure compliance with Part L of building regulations. This service helps developers achieve EPC ratings and meet carbon reduction targets efficiently.

Our air leakage testing services identify building envelope inefficiencies through diagnostic smoke testing and pressure differentials. We provide remediation advice to achieve compliance with Part L and improve energy efficiency in residential and commercial properties.

We perform sound insulation testing to meet Part E building regulations. Our engineers use calibrated equipment to measure airborne and impact sound transmission between dwellings, ensuring compliance for new and converted properties.
Energy Certification
We provide domestic and commercial EPC certification for new builds and conversions. Our assessors create energy performance certificates that detail efficiency ratings and improvement recommendations while ensuring compliance with current regulations.

I have used At space Ltd for the first time this year on my flat conversions in Hitchin .I noted the reviews from previous clients and they were proved correct in all their words about their quality and professional approach to completing the various requirements I needed to meet Building regulations and have my conversions signed off. I must say they are a breathe of fresh air with all aspects from the beginning to the end and I will be using them without hesitation for all my future projects. Regards Dave Graham (BCW Builders)

Excellent customer service from everyone I dealt with at the AT Space office, Joe and Ryan (on the phone booking surveys) and prompt courteous field engineer Rhys who performed our survey. No question was left unanswered and the team assisted us from the outset. This can be a complicated field, but with experts like these on your side, the process is so much easier and less stressful. Highly recommended.

Atspace have been great to work with and always got our certificates to us quickly. We've used them on a number of occasions. No problem with recommending their services.

We had an air test completed on our new build by ATSPACE Ltd, and Ryan was supportive along the way with what we needed and supported us via email during the process, which was booked initially via a phone call. The engineer Keith was very pleasant and courteous and conducted our test professionally and with knowledge and understanding of our requirements. He even went out of his way to arrange at the same time air flow tests on our fans for building regulations which we had not organised and with one phone call this was also sorted on the day. The company was recommended to us from a friend
