The Oftec and Corgi logos which you see on these pages can only be used by companies who are registered with these two organizations. All of us at Anglesey Gas & Oil Systems hold certificates of competence issued by Oftec on completion of training courses held at Trianco Redfyre, Sheffield and Coleg Menai, Bangor. The Oftec website lists all accredited engineers and will indicate that we are able to install, service and repair a wide range of oil-fired appliances. Consumer demand led us to register with Corgi following training and accreditation. We are able to provide a similar service offering installation, routine servicing and repair of a wide range of natural gas and LPG appliances. As Rayburn Guild Engineers, we have attended product training courses with AGA Rayburn at Telford and hold certificates of competence in maintaining their products.

We are also dedicated engineers for Alpha cookers of Thatcham. Stanley cookers have also asked us to provide a service to their customers in this area and carry out warranty work where necessary.
