Branch Manager

Retrofit coordinators are an absolute pleasure to work with,

Alex and his team have guided and advised Dodd Group with the initially rather complicated PAS2030/2025 processes.

With Alex’s support we were up and running in the world of PAS within a matter of weeks, we have now successfully delivered many projects.

Alex has introduced Dodd Group to new clients and we look forward to working with retrofit coordinators for many years to come.
