Our nationally recognised planning and the environment solicitors provide expert advice on the full range of contentious and non-contentious planning and environmental law issues.

We advise in relation to all forms of development and encompassing issues of housing and commercial development (including affordable housing), transportation, leisure and tourism, education, ecological and cultural heritage, contaminated land and pollution and enforcement.

What sets us apart and continues to bring clients back to us time and time again is our consistent ability to deliver timely commercial advice and to solve, rather than create, planning problems. Our experienced practitioners work alongside our clients and guide them through the complexities of the planning system and fast changing environmental laws.

The team is ranked by The Legal 500 and Chambers UK legal directories. Several of our lawyers have served in local government legal departments advising all tiers of local government.
