A dedicated team of industry experts

JHAI Ltd is an approved inspector, licensed every five years via the Construction Industry Council (CIC) to carry out building regulations approvals (building control) as an alternative to local authorities. The company was formed in 1999, as Jon Hollely Associates (Innovation). Today the company is under new ownership and is now referred to by its initials, J.H.A.I.

The team behind JHAI’s success: our technical experts, department heads and directors all work together to ensure that we deliver the very best services to construction professionals and individual property owners. Our key people are all available for you to contact.


“The cost-effective and friendly team ethos that JHAI demonstrates both in administration and on site ensures we will continue to use their services for years to come.”

Gareth Elvidge, David Salisbury Ltd

At JHAI, we want to run our business as ethically as possible. We know that the world doesn’t begin and end with building regulations, and we believe that wherever possible, we should use our organisation to help the wider community. We take our responsibilities to our staff seriously – we want to help them grow in their career paths and achieve their aspirations.
