Whilst installing a conservatory is a fantastic idea, homeowners are regularly unsure over the requirements regarding FENSA certification and compliance with Building Regulations. So to help you learn more on the subject, we’ve created this short, informative post.

What is FENSA?

FENSA is a competent person scheme (CPS) set up in 2002 for the replacement of windows and doors in England and Wales against Building Regulations. It covers the replacement of external windows, doors, roof windows and roof lights in domestic properties on the original foot print of the property where the use or size of rooms has not been altered.

What is a FENSA certificate?

A FENSA certificate is a document proving that installation work which has been completed by a FENSA accredited member is compliant with the relevant Building Regulations. For homeowners, it’s important any FENSA certificates you’re issued with are stored safely, because if you decide to sell your home in the future the solicitor of the person buying your property will request a copy.

Does the scheme apply to conservatories?

In a word, no. Conservatory, orangery or porch installations do not require FENSA Registration from a FENSA Registered Business, meaning a FENSA Certificate is not required. However, they must be compliant with Approved Document N, which covers Building Regulations for glazing.

Are they ever exempt from Building Regulations?

However, there are occasions when conservatories are exempt from certain Building Regulations. Such exemptions occur if:

  • Only intended for domestic use
  • Built at ground level and the floor area is less than 30m2
  • Not used for sleeping accommodation.
  • When the glazing in the walls are constructed from at least 50% translucent or transparent materials and the roof at least 75%, excluding any existing walls.
  • The construction of an conservatory or orangery does not affect any existing drainage system.
  • If heated, the conservatory must have separate heating controls

Replacing doors, windows, roof windows & skylights on an existing conservatory

As these types of replacements are covered by the FENSA scheme, if any such replacements are performed by a FENSA accredited member, a FENSA certificate will be issued to you accordingly.
