What Our Customers Say

"D & N promptly arrived and suggested a number of layouts tailored to our requirements and budgetary constraints. After all agreeing on a proposed plan, the work was carried out swiftly and with a minimum of disruption, often working unsociable hours during the weekend. I was greatly impressed by their high standards of workmanship and I therefore would have no hesitation in recommending D & N to anyone who wished to contract them for such work."

Mike Wilde Coatings, Manager, Gooch and Housego Ilminster.

"D & N carried out a comprehensive risk assessment as part of our project feasibility studies. The level of detail and professionalism displayed were excellent. The risk assessment was performed very efficiently and offered unrivalled value for money. I would thoroughly recommend them."

Dr Antulio Tarazona, MD Echerkon Technologies Ltd.

"D & N offered a professional, courteous and cost-effective service and the work was completed on schedule. Excellent communications, attention to detail and the use of the highest quality components made for a smooth installation of pipework into our clean room while working around the daily research activity which continued uninterrupted. Highly recommended."

Chris Coath, Bristol University

"D and N Installation and Design Ltd provided a bespoke high pressure pipework installation for Cardiff University's Gas Turbine Research Centre (GTRC). The work conducted by D&N was integral to the success of a new five component gas mixing facility that was being installed at the site for future research in the areas of alternative gaseous fuels for power generation gas turbines. I would definitley work with D&N again and would be happy to recommend them to a third party."
