The Building Register manages the industry's largest database of subcontractors and suppliers. The database is accessed via the web site buildingregister.com and is a FREE service that allows clients, local authorities and main contractors to find the subcontractors and suppliers they need to tender for work. The Building Register Enquiry Alert Service allows users to pick vendors from the site and email to them project and package enquiries for them to respond to. To save time and money users are keen to only select vendors for pre-qualification that they know are compliant with CDM regulations.
