What Clients Say About Us


We used Greenovation for the required pressure test on our new build at Wettenhall Cheshire.

We found the company to be punctual, efficient and totally professional and would highly recommend their services.

Mark Buxton

Greenovation have completed air pressure testing across numerous new build housing sites for me for a regional residential builder across Shropshire, Staffordshire & Cheshire. Booking in is never a problem – usually with short notice and tight deadlines to achieve Part L building regulations for CML dates which Greenovation are always helpful to accommodate.

    Greenovation and iATS Registration

    The business is officially registered under the Independent Air-tightness Testing Scheme (iATS) which has replaced the British Institute of Non-Destructive Testing (BINDT) as the body responsible for maintaining the professional standards of air-tightness in the UK.

    Crucially, iATS registration has enabled Greenovation to extend the scope of its work into both domestic and commercial construction. More specifically, it allows Greenovation to test any building up to 400 cubic metres in size (which complies with L2 requirements under UK Building Regulations).


    Greenovation’s Level 1 iATS Accreditation is a measure of the company’s commitment to best professional practice; to keeping abreast of the latest air testing techniques; and its ongoing involvement with Continuous Professional Development (CPD) – and all the customer benefits this brings in maintaining professional standards.


    As an iATS-registered consultant, James Spooner has demonstrated competency levels that meet the high standards set out under the scheme. For clients, this means that Greenovation has the professional and physical resources to measure and quantify the key elements of a building’s ‘air tightness’.

    Equally important is the company’s capacity to handle the whole process from recommending what action needs to be taken to ensure properties comply with the relevant UK Building Regulations, right through to implementing any remedial work that may be needed.
