JMS Transformers was established in 1991 by brothers, Sean and Jeff Harris. Having started out in Sean’s Garage, the company has massively expanded over the last 3 decades, with the latest step being moving into a purposefully modified 22,000 sq. ft. factory.  Due to our recent move, we are proud to announce that our stock capacity has increased by over 200%. We can now despatch certain goods within hours of your order and they can be with you the very next day.

JMS manufactures a range of Transformers from 25VA -1000KVA with both ease and precision. At JMS, we pride ourselves on our fast turnaround and our rapid deliveries which range from as little as 1-3 days for standard orders. We also offer Voltage Stabilisers and Voltage Optimisers for specific applications.

We also offer an investigative rewind and repair service. With our specialist Winders, who are dedicated to rewinding emergency breakdowns, we can get your product back up and running swiftly and effectively.

Waiting on the other end of the phone is our Sales Team, who are at hand to offer you an instant quotation and to offer advice on how your needs can be met. No job is too small or too large. We strive to ensure that you will receive the product and service you deserve.

Along with our customer service, the pricing of our products makes us one of the industry’s prime manufacturers. Our Transformers are manufactured onsite, in the UK and firmly comply with British and European Standards, meaning that you can have upmost confidence in the safety and reliability of our products. Along with great base prices, we offer rapid delivery at no extra charge and do not penalise customers with fees for prototype or one-off orders.
