BDB Pitmans retains a strong and large practice that is capable of handling the full range of parliamentary work, acting for a range of transportation infrastructure providers, landowners, registered charities and local councils on the promotion of private bills and secondary pieces of infrastructure legislation as well as on objections to parliamentary infrastructure projects. In addition to having prepared and promoted private bills for the likes of Royal Albert Hall and the Bishop’s Stortford Town Council on land expansions and charter updates, the team maintains a prolific record of preparing Transport and Works Act Order applications and has handled Development Consent Orders in connection with airport and highway expansions. Energy and carbon capture projects are a further area of specialism for the team, which is led by planning expert Mark Challis and further benefits from the expertise of experienced Roll A Parliamentary Agents Nick Evans, Sarah Clark, and Angus Walker, all of whom are well-equipped to promote bills for major infrastructure schemes.
