Simpson & Allinson

Geoff Simpson and John Allinson, who still own and run the business today, set up Simpson and Allinson Limited in 1978. The company has been manufacturing steel framed buildings ever since, keeping up to date with the latest innovations. including the design and manufacture of the award winning "Roundhouse".

We believe that as well as the excellent standard of our buildings, the success of the company is much attributed to the dedicated team of people who work day in - day out, with farmers, landowners, architects and business people, making sure that their every need is looked after and that the product is designed around the end users requirements.

Clients who require buildings, also require building materials and a variety of hardware to use in their new premises. Geoff and John created S&A Builders Merchants to satisfy this demand. Now operating from two branches with over 5,000 products in stock, we have an experienced team of friendly staff to offer the high level of customer service that you deserve.
