The Bowyer Engineering Story

Bowyer Engineering Limited was founded in Clerkenwell in 1946 when the Company initially worked in the provision of tooling and equipment for the telecommunications industry. In 1969 Bowyer Engineering, by now specialising in batchwork machining, re-located to a new greenfield site in Andover as part of a London “overspill” agreement. The Company continued to evolve by establishing working relationships with other companies and began to develop and construct automated special purpose machines for use in diverse high-tech industries following a chance opportunity to design and build robotic welding fixtures for a specialist supplier.

Bowyer Engineering enjoys an excellent working relationship of over 60 years with Rolls-Royce aero engines who remain one of the Company’s largest customers. The Company initially supplied mercury slip ring units and inhibiting rigs, but much of the work now carried out is the sub-contract Research and Development of special processes for automation of single crystal wax casting and composite pinning processes. Other long-standing blue-chip customers for who we continue to provide support include IAE, Hydro, UYS and QinetiQ.

Bowyer Engineering also continue to operate in the batchwork machining field and have recently undertaken a major review of machining processes allowing a greater throughput from our dedicated 1,100 m2 machining facility. We specialise in the machining of a diverse range of materials that include super duplex, stainless steel, nimonics, Inconel, aluminium and mild steel. In 2015 5 axis capability was introduced, from which we have never looked back. We have embraced this capability and now continually push the envelope of this technology be it with tooling programming techniques of complexity of design.

Bowyer Engineering have gained a reputation as solution providers for part or complete projects and have the ability to evolve into new areas as and when required. Following-on from the success of the early special purpose machines, and taking advantage of opportunities whenever they arise, Bowyer Engineering diversified into Instrumentation in the 1980’s and subsequently expanded into NDT support early in the 21st century with the provision of EDM notching facilities.

In November 2018 we started our epic transformation of the site, while in the middle of a major customer support project. Replacing the roof, and re-locating all of our production, assembly and inspection, while maintaining full production capability, was no mean feat. We now have a class leading facility with space for expansion or flexibility to diversify our capability as required.


We have continued to invest in machinery, facilities and staff. Finishing off the building transformation with a video conferencing facility which has been beneficial during the Covid-19 era.

On St Goerge’s day 2021 we reached the milestone of 75 years in business. With some appropriate distancing and timing, we were able to celebrate with some local customers and the loyal staff. We continue to strive to deliver customer satisfaction, while maintaining our friendly family business perspective.
