What You Can and Can’t Register With a Competent Person Scheme

Many works must meet Building Regulation requirements but not all works in dwellings are notifiable to the Local Authorities. Therefore, Competent Person Schemes can only register works on a contractor’s behalf with the Local Authority that are deemed notifiable. Generally speaking, conservatories and porches are excluded from Building Regulation notification requirements.

Conservatories and Porches

There are some exemptions from the energy efficiency requirements and Local Authority notification in Building Regulations for some conservatory and porch extensions. The exemption for conservatories or porches in Building Regulations:

  • Which are at ground level;
    • Where the floor area is less than 30 m2;
    • Where the existing walls, doors and windows in the part of the dwelling which separates the conservatory are retained or, if removed, replaced by walls, windows and doors which meet the energy efficiency requirements; and
    • Where the heating system of the dwelling is not extended into the conservatory or porch.

In circumstances where any conservatory or porch does not meet all the requirements above, it is not exempt from Building Regulation compliance and therefore, must comply with the relevant energy efficiency requirements and is notifiable.

Certass Guidance for registration of existing porches with Certass  

When determining if replacement doors or windows are notifiable, you need to consider the following two factors:

  • If the porch/conservatory was removed, could the remaining door to the property be considered an external grade door? i.e. is it weathertight and secure?
  • Is the porch/conservatory heated from the property’s main heating system? i.e. is there a radiator in the porch/conservatory fed from a boiler that heats the rest of the property?

If the door in the example above is not an external grade door at the time of the replacement, then the windows and doors in the porch/conservatory are notifiable.

If the porch is heated from the main property heating system, then the replacement windows and doors in the porch are notifiable irrespective of whether the secondary door is / is not external grade.

Wall Openings

Where a wall opening has been widened as part of the replacement windows and /or doors installation then these woks cannot be registered with a Competent Person Scheme and these works must be notified via the relevant Local Authority or through an Approved Inspector.
