Lawful Development Certificates & Change of Use
Expert advice on lawful development certificates and change of use applications for residential, commercial and rural developments.
Establishing Lawful Use & Development
Not all development requires planning permission, but obtaining formal confirmation can provide valuable certainty for property owners, developers and purchasers.
We advise on applications for Lawful Development Certificates relating to both existing and proposed uses or developments. These certificates provide legal confirmation that a particular use or form of development is lawful under planning legislation.
We also advise on Change of Use applications across a wide range of sectors, including residential, commercial, retail, agricultural, leisure and mixed-use developments.
Our planning consultants prepare the supporting planning case, gather the necessary evidence, liaise with Local Planning Authorities and negotiate throughout the application process to secure the most favourable outcome for our clients.
Whether you are converting commercial premises into residential accommodation, changing the use of agricultural buildings or regularising an existing use, we can guide you through every stage of the process.
