Our Development

Allied Welsh was founded under the vision that your loft conversion be completed by a single specialist company, with no sub-contractors. This single defining concept has allowed us to gain massive experience across disciplines; from our Survey Team, to our uniformed carpenters, roofers, plumbers and electricians.

Our years of success have led to the expansion and refinement. of our operation to include our trade premises, joinery, and in house steel fabrication, increasing efficiency and reducing time on site.

Our staff are the heart of the company, consistently staying up to date with the latest regulations, technologies and qualifications. In 2005 Allied Welsh’s commitment to its personnel was recognised by the UK Government and awarded The Investors in People Award for employee engagement, retention and development.
