What makes us different?

Standard directories make their money by providing poor quality leads and charging you for the privilege. Building firms lose huge amounts of money and valuable working time providing quotations for jobs that are speculative, under-budgeted or simply time wasting. At Construction Supermarket we do things differently. All our projects are vetted to ensure planning permission is in progress, the client has a realistic budget for their build and a good set of architectural drawings in place so you can put together an accurate, competitive and profitable quote. We don’t provide leads, we provide a leading service.
