About JHAI Ltd

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 (so that’s jay-aitch-ay-eye).

Our Mission
We have handled over 65,000 Building Control applications in the last five years, 17,000 in the last year alone. By volume we are one of the biggest Approved Inspectors across all sectors in the UK, possibly the single largest AI in the housing sector. We now also provide a range of Energy Assessments and additional services.

We take our responsibilities to our clients seriously – we know that we are trusted with professional reputations and lifetime investments. Our promise to you is that whether you are a multi-national developer or a one-person self-builder, we at jhai will do everything we can to provide you with the best, most efficient and cost-effective Building Control service possible.

Building Control
We offer Building Regulations Approval the way that it should be: fast, helpful and intelligent.
  • We provide Building Control for all types of commercial and domestic projects.
  • We have carried out over 17,000 approvals this year alone.
  • We offer the same high level of service whether you're a self-builder planning your dream home or a major developer needing quick decisions on a national roll-out.
  • We aim to make your projects easier and save you money.
  • We cover all England and Wales.
We handle everything from Initial Notice, Plan Checking and Site Inspections through to Final Certificate. If you’re unfamiliar with the Approved Inspector Building Control process click here. We look forward to working with you.

Energy Assessments from ENERJI+
You’ll probably need Energy efficiency and other certificates to complete your Building Control submission. Our in-house Enerji+ department can provide all the Energy Assessments you need, making the process as streamlined and cost-effective as possible. Read on to find out what you need or email Dave Hoskin or call 01308 428022.

Self Build
We offer an unrivalled service to small scale domestic developers, self-builders and homeowners. In 2015 we approved over 12,000 Building Control applications in the housing sector - more, we believe, than any other Approved Inspector.

Building Regulations can seem daunting for those with limited building experience. We passionately believe in providing the same excellent service and value to householders as we do to construction industry professionals. Since 2010 we have exhibited at Grand Designs Live and National Homebuilding and Renovating shows to get first-hand knowledge of what homebuilders want from us. We have a stand all year round at the National Self Build and Renovation Centre and We are corporate business partners of NaCSBA (the National Custom and Self Build Association).

How we can help with your Self-Build project:
  • Easy online application and payment
  • Helpful advice at plan check and site stages
  • Clear explanations of what to expect
  • Seamless SAP, Sound and Air service from our Enerji+ team
Other Services
