Tell us about your site or building — we will assess change of use viability and permitted development rights at no cost, with no commitment.
What is change of use — and do you need planning permission?
Change of use is when you want to use a building for a different purpose than it was originally designed or approved for. For example, converting a former office into flats, turning a retail unit into a restaurant, or changing a warehouse into a mixed-use development.
In England, every building falls into a planning use class. Moving between some classes is allowed automatically under Permitted Development rights — but many conversions still require a formal planning application. Getting this wrong can be costly.
Our free pre-purchase feasibility assessment tells you exactly which route applies to your property, what is achievable, and what the risks are — before you spend anything on the building or on fees.
