Is planning permission required for a conservatory? This is one of the most commonly asked questions we receive from homeowners looking for a new conservatory in the UK. So, here’s our expert answer!
Do you need planning permission for a conservatory?
In most cases, you will not need planning permission for a conservatory. This is because conservatories are considered permitted development and are therefore exempt from planning permission. Permitted development rights are a national grant of planning permission that allow certain building works and changes of use to be carried out without having to make a planning application. This is brilliant news for homeowners, as it makes your life a lot easier, and it means adding an extra room to your property doesn’t come burdened with any extra paperwork.
What is the difference between building regulations and planning permission?
Building regulations are designed to ensure that buildings are designed and constructed in such a way so that they’re safe, energy-efficient, and accessible. For example, new builds must have robust foundations, have the correct insulation and be tested to ensure their electrics have been installed properly. For public buildings, it may be factors such as wheelchair access and the inclusion of sanitary facilities. Planning permission, on the other hand, is designed to preserve the area in which the building is located. After all, when changes are made to buildings, they not only impact the homeowner, they also impact on neighbours and the general public as well. Through the planning permission system, an unregulated free-for-all is prevented. To summarise, planning permission aims to control the way that towns and cities develop and to control their appearance. Building regulations are concerned with the specific construction techniques and materials on the building in question.
What are the size limits on conservatories?
Conservatory size limits on the dimensions of the conservatory depend on the property;
- If the house is detached, the conservatory should be no longer than 8 metres.
- If the house is semi-detached or terraced, the limit is reduced to 6 metres.
In either case, planning permission for conservatory extensions in the UK has a maximum height limit of 4 metres for a single-storey extension. So, if you’re wondering about the planning permission for conservatories on a semi-detached house, the conservatory size limit is 6 metres and it can only be one storey high. Although, new planning rules that came into effect from September 2020 now allow families to add two storeys without full planning permission.
Do I need planning permission for a conservatory with a tiled roof?
As long as you stick to the other criteria we’ve previously explained, you shouldn’t need to apply for planning permission if you opt for a modern tiled conservatory roof.
Planning permission for areas of outstanding natural beauty
These conditions vary slightly if building on ‘designated land’, which includes national parks and areas of outstanding natural beauty. For more information, you can visit the Government’s Planning Portal website, which details the current legislation.
