Do I need Planning Permission for a Mezzanine Floor?

A mezzanine floor is an additional floor that is installed between the main floor of a building and the roof. The name comes from the Italian word ‘mezzo’ meaning ‘half’ and it is often situated halfway up the wall in the middle space of the building, although there’s nothing to stop a company from installing more than one mezzanine if there is adequate headroom and the design meets regulations.

A mezzanine is an ideal way to expand the available floor space of a business without having to go to the trouble of extending a building or a costly move to another premises.


As mezzanines are semi-permanent floors and are usually free-standing, they can be dismantled and relocated when necessary, so they don’t usually require planning permission. However, they do have to meet certain building regulations, as explored below.


When would planning permission be needed?

There are a few exceptions to the general rule that a mezzanine doesn’t need planning permission. A mezzanine will need planning permission if the building needs external alterations to install it. Altering the external aspects of a building, including adding or removing doors or windows would necessitate planning permission.

If the intended mezzanine floor is for a retail unit’s usage and is over 200m2 it will need permission and if the site had permissions restricted to develop previously, then extending the floor area with a mezzanine floor will need planning permission.


What is Building Regulation Approval?

Most mezzanine installations will need to apply to a building control body, such as the local council. An inspector will want to make sure that your mezzanine floor meets the relevant regulations laid out in the updated Building Regulations Approval 2010. There are certain sections that are relevant to a mezzanine floor installation, such as:

1. Structural safety

Without a doubt the primary concern for your mezzanine installation is the structural safety such as floor loading to ensure it is fit for purpose – these are laid out in the Building Regulations. At Advantage, we are used to handling all the paperwork and compliance related to these regulations, giving you peace of mind that your mezzanine will be installed safely and efficiently.

2. Fire safety

If your mezzanine floor is going to be used for storage only, is not enclosed beneath the floor, or doesn’t exceed half of the total floor area of the building in which it is placed, then the fire safety regulations aren’t applicable. However, if your mezzanine is going to be for office spaces and will have a number of staff working on it, or members of the public, such as a mezzanine in a retail unit, then it will definitely need to comply with Fire Safety regulations. Advantage will ensure your mezzanine is installed with materials that give an hour’s fire protection, which will comply with the building regulations pertaining to fire safety.

3. Protection from falling

This part of the regulations applies to staircases, ramps, guards, handrails, and skirtings. These all need to be considered during the planning and design stage to ensure the safety of all those moving up and down and between floors.

4. Access to, and use of, the building

During the design process, access to the mezzanine needs to be considered, particularly in regard to disabled access. Since the Equality Act 2010, organisations are required to promote equality for people with protected characteristics and this includes accessibility to new buildings and installations for disabled people as stated in the regulations.
