Howard Butler Ltd

Howard Butler Ltd has been manufacturing panel meters, current transformers, relays, transducers and associated products in our UK factory for over 85 years.

Howard Butler Ltd has ISO 9001:2008 approval with a constantly reviewed quality policy. This ensures that through our  vigilance, control, design methods and accountability throughout all stages of design and manufacture quality is designed and built into our products. Our in-house design engineers are able to work with customers to provide custom solutions where our standard product range is not applicable. Our policy is one of continuous improvement, therefore the HOBUT range is regularly added to with new products, mostly designed to IEC, BS, or DIN specifications.

 

We hold extensive stocks of vital components to ensure quick delivery of both standard and special
products. Customer satisfaction is central to the aims of Howard Butler Ltd, with our fully integrated
computer system closely controlling orders, enquiries and stock.
