About Custom Transformers

Custom Transformers Ltd specialise in the design and manufacture of electrical transformers and wound parts. The company was formed in Malmesbury in 1972 with simple founding principles: a total commitment to quality, effective service for all customers regardless of size, and a partnership approach, with products designed hand in hand with customers to meet exact specifications.

Dedicated staff manufacture over 4,000 items per week. Continual investment in new plant and processing equipment, along with regular reviews of production techniques, ensures a competitive market position for the benefit of all customers. This has continued with the building of a new factory in Easton Grey, designed around our founding principles of quality, service and partnership.

Since many transformer applications require custom solutions, we have developed extensive experience tailoring products to specific customer requirements across diverse areas including alarm systems, electronic equipment, machine tools, telecommunications, control drives, and oil, gas and water products. We can also help control offshore requirements, taking over customers' purchasing to reduce stock holding, quality problems and lead times, while providing a design service with fast turnaround of samples and short lead times on start-up orders.
