Thurston Engineering Ltd

We Are Thurston Engineering.

Thurston Engineering Ltd evolved from a business started by Eric Thurston in 1938, at Ongar Essex, and was originally set up to overhaul motor car engines.

Nearly 75 years on, the business has developed and expanded to include a wide range of allied services which we are proud to offer in today's market place.

The Best of Both Worlds

Our staff are a potent blend of craftsmen who are highly experienced in all aspects of engine reconditioning/repair and the dynamism that accompanies innovative young men raring to keep abreast of all the latest technology.

New Technology allied to Sound Experience

It is a mixture of this deep-seated knowledge and the determination to be at the forefront of new technology as and when it proves itself to be advantageous, that has been largely responsible for the enviable reputation that Thurston Engineering has accrued over the years. This approach enables the Company to offer an invaluable service to both industrial and private customers.

Specialised Work Requires Specialised Workshops

Further specialised workshops have been added over the years to accommodate larger cylinder boring machines, crankshaft grinders and many other modern machines, thus allowing the Company to expand into the heavy commercial, industrial and marine markets. Thurston Engineering is now one of the oldest established engine reconditioning firms in the country. Additionally, in conjunction with our sister company E H Thompson & Son Ltd., we are ideally situated to provide general engineering services with their 3000 hours per month machining capacity.
