Still Here – To Support You

Unrivalled skill and expertise


Since our move away from Rolls-Royce, we have become increasingly aware of various claims that we have closed down or that we are no longer in the business of supporting our engines. Nothing could be further from the truth. Today we support a greater number of Allen engines in more countries than ever before.

The aftermarket function in the UK has its head office at Bedford providing dedicated specialised support for the Allen range of engines. Bedford is also the UK office for Main Plant sales.

Before considering suppliers of non-genuine, second hand or reconditioned spare parts or suppliers of engineers who are untrained on our products, we urge you to take into account the following:

Allen Diesels experience is unparalleled in the field – some key milestones are below:
