His primary involvement in live construction projects, particularly in property development from both a client and contractors perspective, means he is able to bring real-time and relevant information to our RCAs.

His knowledge and experience mean that he is a valued and respected speaker at industry events and sits on the panel responsible for the RICS’s Guidance Note on the Reinstatement Cost Assessment of Buildings, 3rd edition, 2018.

His vision for BCH sees the company remaining in the forefront of provision for Reinstatement Cost Assessments for the UK insurance market.

He enjoys the buzz of client meetings, particularly those based in many of the country’s most iconic buildings.
