Marshall’s Industrial

Marshall’s began in a garden shed, repairing bicycles. From bicycles we moved onto motorcycles and cars and then in the 1920’s we opened our first garage in Reading, repairing both cars and industrial engines. By 1936 we were specialising in component manufacturing, coach-building and servicing industrial plant machinery.
The 1960’s and 70’s saw us acquire an NSU franchise, then Audi and finally Volkswagen. We acquired a second dealership in Reading in the 1980’s. Also, at this time we started assisting Volkswagen UK with their industrial customers, including supplying engines, vehicle components for OEM use, and minibus/camper converter components.

Branching Out
In 1995, we separated the industrial business from the car dealerships and were proud to become the first appointed independent Volkswagen industrial engine distributer in the world.
Another 13 years on and we were appointed as the IMPCO gaseous fuel systems distributor for the UK.
In 2015 we were appointed as Doosan engine range distributor for the British Isles and Republic of Ireland.

Years of industry experience means we know our clients, understand their requirements, and respect their deadlines. Our services and processes are designed to reflect this. We will not just sell you products and expect you to just get on with it. With Marshall’s you get so much more than just an engine or component.

impco gaseous fuel systems

IMPCO develops and manufactures solutions for the medium and heavy duty on-road and industrial markets. Our products are designed and manufactured to be durable, reliable, and enable internal combustion engines to operate cleaner for the environment and more economically for the owner.


Marshall’s Industrial are a good company to deal with, knowledgeable and reliable. We have been very happy with the way they look after us and will definitely be using them for the foreseeable future.

We have been a customer of Marshall’s for over 25 years and can honestly say that they are the most reliable supplier we have. The depth of knowledge they have about the components we need is not available anywhere else.

Choosing an engine partner for our on-going development projects is a critical decision. I have never had a reason to regret working with Marshall’s Industrial, the team there look after us very well and even when things go wrong they are there for us.

Buying from the official distributor gives the assurance of getting the right maintenance parts direct from the manufacturer, having had bad experiences buying from the internet I will always use them for IMPCO products in the future.
