More and more people are choosing to renovate their existing homes as opposed to moving, rooflights and roof windows play a key part in bringing natural daylight and fresh air to any dwelling. As the uptake of rooflights continues, we find our team being asked the same question “Do I need planning permission for rooflights?”
Do You Need Planning Permission For Rooflights?
The answer is not a simple yes or no, as numerous factors dictate whether you will need to apply for planning permission. But the good news is, many rooflight projects do not require planning permission, as the installation of rooflights is seen as a ‘Permitted Development’ as long as the rooflight or roof window does not protrude more than 150mm above the roof plane and no part of it is higher than the highest point on the existing roof.
If the rooflight will protrude more than 150mm above the existing roofline, you will be required to apply for planning permission. If you do not apply for planning permission when you are legally required to, you could face an unlimited fine or a ‘Stop Work Notice’
Planning Permission In Conservation Areas
You will also be required to apply for planning permission if you live in a conservation area, which is defined as “An area of special architectural or historic interest, the character of which it is desirable to preserve or enhance”
Houses in conservation areas do not automatically have permitted development rights, meaning any works will require planning permission. The regulations in conservation areas limit the structural changes that you can make to your home to keep its aesthetics inline with the heritage of the area.
There are specially designed products for installation in conservation areas to ensure compliance with the strict regulations. For example, some specialist conservation roof windows are expertly manufactured with a black painted outer frame, black supporting flashing or an integrated mullion bar to meet planning requirements in conservation areas.
Similarly, these stringent planning rules apply to all listed buildings to keep their historic heritage.
Compliance With Building Regulations
Installing a rooflight or roof window will significantly alter your roof, therefore you need to ensure that your works comply with Building Regulations published by the UK government.
You need to ensure that your roof will be able to carry the additional weight of the rooflight as well as providing sufficient insulation against heat loss.
The building regulations ensure the health and safety of people in and around all types of buildings (residential, public and commercial). They also exist to ensure compliance to factors from hygiene to fire safety.
The Building Regulations that impact rooflights are:
-
Part F - Ventilation
-
Part K - Protection From Falling
-
Part L - Conservation of Fuel and Power
-
Part O - Overheating
-
Part Q - Security in Dwellings
The Building Regulations cover the construction and extension of buildings as well as the replacement of windows and doors, therefore you will need to apply for building regulations approval to ensure that you are adhering to the regulations. You should submit an application before the works are due to start, a Building Control Officer will inspect the building work at various stages throughout the project and award a Completion Certificate once the work is finished, meeting all relevant regulations.
If you do not want to apply yourself, you can hire a “competent person” as they can self-certify that their work complies with buildings regulations and provide you with a Completion Certificate.
