Certass currently operates three separate certification schemes for Installers within the building refurbishment industry.

These certification schemes operate under Government license or Government sub-license. 

Within the building refurbishment market the two key areas that our licensed schemes fall into for the operation of a Competent Person Scheme are Glazing and Insulation, other trades are covered under our Green Deal and TrustMark licenses. Details of the scheme scopes for Installers can be found on our Home Page. Certass also runs a number of other certification schemes licensed directly by Certass.


By using a
Certass Competent Person registered contractor
you’ll get >

  • Protection of deposit taken – in line with the insurance company’s policy wording
  • A guarantee covering the installation
  • An insurance policy to cover the contractors guarantee, should the Certass registered contractor cease to trade
  • An easy way of registering your installation with your Local Authority at no cost to you


What are Competent Person Schemes?

  • Competent Person Schemes were set up by the government to provide an alternative to submitting a building notice or using an approved Local Authority inspector for certain home improvements and building works.

  • All Certass registered contractors are vetted to ensure they are qualified to carry out installation work in accordance with the current building regulations and, once an installation is complete, Certass provides you with the Building Regulation Compliance Certificate for the work carried out.

  • Alternatively, notification and approval of the completed work can be sought from your Local Authority’s Building Control department directly. This can cost in excess of £250.

What are Building Regulations?

  • The Building Regulations 2010 (as amended) are a set of mandatory functional requirements established in law to protect the health, safety, welfare and convenience of building users and people who might be affected by buildings or matters connected with buildings. They also define the thermal performance of buildings and building works.

  • The Building Regulations are not concerned with aesthetics (what the installations looks like) or the quality of the installation so long as it does not adversely affect the thermal performance or the health, safety, welfare and convenience of building users and the general public.

  • Therefore poor finishing of an installation such as untidy sealant, large trims or uneven finishes although not satisfactory to a householder may well not breach the building regulations. Such issues are likely to be contractual issues that should be taken up with the installer at the time of the installation.
