Do I need planning permission?
You will need to apply for full planning permission to install, alter, replace or re-locate any plant, air conditioning, ventilation or extraction equipment where any part of the equipment will be fixed to the outside of the property.
Very small external equipment (for example, a small extractor fan that is not visible from the surrounding streets) may not require planning permission if it does not materially change the external appearance of the property.
Where can I find further information?
Please see policies DP28 (Noise and vibration) of Camden’s Development Policies document (pdf) and Chapter 4 of Camden Planning Guidance 6 – Amenity (pdf) which set out the policy with regards to noise and vibration from plant equipment.
A noise, vibration and ventilation assessment will need to accompany a planning application for the installation, alteration or replacement of plant, ventilation, extraction or air conditioning equipment.
Can I get confirmation that I do not require planning permission?
In situations where you may need to prove, or obtain peace of mind that an existing or a proposed piece of equipment is lawful, you can apply for a Lawful Development Certificate.
Am I likely to get planning permission?
If you want to find out whether your proposal is likely to be acceptable, you can apply for pre-planning application advice.
