jhai Ltd is an Approved Inspector, licensed every five years by the government - via the Construction Industry Council (CIC) - to carry out Building Regulations approvals (Building Control) as an alternative to Local Authorities. We have processed over 65,000 Building Control applications in the last five years.

When the company was formed in 1999, jhai stood for Jon Hollely Associates Innovation – but since 2009 it has been under new ownership and is now referred to by its initials, J.H.A.I.
