Certass is Government authorised to operate a Competent Person Scheme and is a UKAS accredited Certification Body. UKAS (United Kingdom Accreditation Service) is a Government approved body which is internationally recognised to accredit Certification Bodies. It accredits a Certification Body against an internationally recognised standard. Certass is accredited to operate product certification schemes against the standard BS EN17065.

Our UKAS accreditation matters! It places a duty upon us to certify our members impartially against agreed standards. It requires that our certification provides confidence to all interested parties including consumers, Governments and industry.

It is very different from the find a contractor schemes advertised on TV. These schemes are basically lead generation businesses that sell your information to contractors to be able to contact you to quote for work. Contractors can pay hundreds, if not thousands, of pounds per year to be a member of these schemes. As you will be able to determine there is a large potential conflict for these types of schemes.

Look for a UKAS accredited certification body to ensure they act impartiality to recognised standards. We are independently checked by UKAS on an on-going basis.

The Process >

1. Before work begins >

Certass contractors will provide you with a consumer contract explaining the work to be undertaken.

We recommend you make notes on your specification to ensure that there are no misunderstandings regarding your requirements.

2. After Completion >

All Certass contractors are required to provide all of their customers with a written guarantee to cover the installation work.

Furthermore, Certass contractors are required to provide you with additional peace of mind in the form of an Insurance Backed Guarantee covering breaches to Building Regulations in the event that they cease to trade.

3. Registration >

Once the work has finished, your Certass contractor will register your installation with Certass within 21 days of the installation being deemed complete.

On your behalf Certass will, where applicable for Building Regulation requirements, notify your Local Authority of the installation completed at your property address. Certass will issue you with your legally required Building Regulation Compliance Certificate as proof of compliance*.

*This will be required by your solicitor should you wish to sell your property. If you’ve lost your certificate, either you or your solicitor can contact Certass directly and order a replacement. There is a small charge of £24 including VAT for replacement certificates ordered 28 days after original issue date.

All Certass contractors must have a formal complaints procedure in place.

In the event that you are still dissatisfied and the contractor has not been able to resolve your complaint after fully exhausting their complaints procedure, you can contact Certass for an independent investigation of your complaint. Click here  for the Certass complaints procedure.
