Parts & Administration

I am the essential back-office support for my husband David. It is quite possible that Dave will not be able to get to answer his calls immediately, and on those occasions you will have the pleasure of talking with me for service appointments, parts requests and any other cries for help.

We have been together over 20 years and I have become quite familiar with the technicalities of Diesel engineering and the Cummins product range.

Our Clients


Vasey Engineering were highly recommended to us; Dave and the team certainly did not disappoint!

We have enjoyed exceptional service at a fair price ever since. For me, what makes Vasey Engineering stand out from their competition is the personalised service that customers receive. I have called them many times, often at night, to ask a question or report an issue and, on each occasion, the response has been swift and accurate.

Vasey Engineering have undertaken all our servicing and maintenance requirements and I have complete trust in the quality of the work. But the level of service that we have received over the years from Vasey Engineering goes way beyond that.

Fantastic service and I have no hesitation in thoroughly recommending Vasey Engineering.

Stephen Long OBEJanuary 2021

David has serviced and meticulously maintained my charter boat's Cummins QSD engines and Bravo 3 outdrives since I bought it back in 2015. I was delighted when he set up Vasey Engineering and I am enjoying watching his business go from strength to strength. Vasey Engineering's expertise, skill and knowledge is unrivalled. They somehow manage to juggle a substantial and varied workload from an impressive, diverse customer base so as to provide a quick, affordable and easy solution to any problems or issues that might crop up.

It is very reassuring to know that whenever I need routine servicing, breakdown repairs, part sourcing or just advice over the phone, they will always be on hand to quickly provide a solution. I've had experience of other contractors that just make excuses. Vasey Engineering just make things work! Thoroughly recommended!

Mike GriffithsApril 2021

This was my first experience with a Cummins engine and so it was enormously reassuring to have such an expert on board for the first service. Dave showed me around all the peripherals and we talked about what to expect from the engine – total reliability.
I am looking forward to a trouble free season and will be back in touch for the next service.
