Here you can read some of the great customer feedback we receive for our fuel polishing and marine engineering services in and around Wiltshire, Hampshire, Oxfordshire, Berkshire, London, Surrey, Wiltshire, Gloucestershire, Warwickshire, Bristol, Somerset, Dorset and Devon.

Allowing the diesel level on our motor cruiser to run low led to it becoming contaminated with water with resultant clouds of white smoke/ steam and engine cut out. Being fairly sure what the problem was I went on line and got a few quotes for fuel cleaning. Joe’s was amongst the best and as he could do the job within a sensible time I booked him.

He did an excellent job at a competitive price on site at our marina in Berkshire and I would have no hesitation in recommending his services


Joe came out at very short notice when we were stuck, travelled a long distance and was prompt, friendly, helpful and sorted the diesel perfectly. Would highly recommend.


Joe came to our location as agreed and cleaned our Narrowboat fuel tank, polished the diesel and changed the fuel filters. His equipment was in excellent condition and there were no leaks. Not a drop was lost in the canal.

Joe took the trouble to show me the contamination he found in the tank, such as water, rust and diesel bug, and made sure I had all the good fuel from his filtering equipment back in my tank.

The engine hasn’t missed a beat since and I wouldn’t hesitate to recommend his services.


Joe Crouch was recommended to me by the marina staff. He arrived promptly at the arranged time and set about rectifying our fuel problem. Friendly and knowledgeable he went above and beyond our expectations and did a thorough job with no fuss or drama. Our engine is now running happily again thanks to Joe. We would recommend him to anyone and after our feedback to the marina management I’m sure he will be contacted by anyone there who needs his services.

Thoroughly professional.

Hi Joe

Thanks for carrying our the oil polishing so quickly, efficiently and cleanly. Great value compared to quotes provided by some of the larger companies. Friendly service, would highly recommend. Thanks


I’ve used Joe several times over the last few years for servicing the boat. He’s always arrived on time, done a great job and offered practical advice about how to keep our engine in top condition in between. If anyone asks I always recommend him.

Hi Joe,

Would just like to thank you and leave a review for the excellent service you provided when I needed my fuel tank and system polishing and cleaning. We arranged a date and a time for Joe to come and clean my tank after a engineer noticed diesel bug in a routine service of my engine. Joe took the call and was with me within two days and carried out a full fuel polishing and check of the system. He was very thorough and knowledgeable and showed me what to look for in-case the bug came back and how to treat. I am very happy with his work and would highly recommended him to anyone that needs similar maintenance and help.

I have used Joe from JC fuel polishing for over two years now, Initially to sort out an issue with water in the diesel.

Joe very quickly established the problem was a leaky fuel cap and replaced it, after polishing the fuel and cleaning the tank. I now get the fuel polished every year.

Joe offers a great service, top notch, always willing to help, with sound advice .
I would highly recommend Joe, not only for fuel polishing, but all aspects of boat servicing. Great job.
