A loft conversion does not typically require planning permission because the construction generally happens within your property. You can check with our advisors though if you need to obtain this kind of document since this is a crucial document. Failure to have this in hand may result in a fine or may lead to imprisonment. Some factors that may ask for planning permission are if your house is located in a conservation area or if the loft conversion will be extended higher than the highest part of the existing roof in your house.


If your property is a semi-detached or terraced house that has a shared wall, then you definitely need to have a party wall agreement in hand before the loft conversion begins on your property. This is to comply with the Party Wall Act of 1996 which was devised to prevent building work that can compromise any structural integrity of a shared wall, and also, to avoid disputes between neighbors.
