Fantastic to deal with, great communications. Did diagnostics and highlighted an issue for me to look in to. The whole job finished within an hour. Truck is now running a lot better and it also looks like I will be getting better fuel consumption. Thanks for the great work, highly recommend.

Adrian was absolutely brilliant from start to finish. His communication was spot-on — friendly, helpful, and professional throughout. He explained everything clearly and made the whole process really easy. The quality of his work is amazing — my car feels incredibly smooth after the carbon clean, like it’s running better than ever. You can tell he really takes pride in what he does. Highly recommend Adrian to anyone thinking about getting their car carbon cleaned — top guy and excellent service!

Cannot praise Adrian enough for his services and support. I had an engine fault light come on the car suggesting a dpf error. I contacted Adrian for a dpf clean and he was very honest to say he didn't think I needed one. I booked in to have an engine clean and diagnostic and replaced the dpf sensor myself. The communication from Adrian prior to the visit was excellent, checking all was OK and advising on arrival time. On the day Adrian turned up on time and carried out the engine clean sending me the diagnostic reports. Afterwards the car def runs smoother, over the last 1200 miles I have had another 3mpg which doesn't sound like a lot but bear in mind it's an old merc that's done 106k so going from 44 to 47mpg and 33k miles a year saves me 48 gallons or 217 litres of fuel which means the engine clean has paid for itself in fuel usage alone after 4 months driving and I expect the engine components to last longer. Def something I will have done every year and would strongly recommend to have done. Apart from the clean the support and advice from Adrian was excellent and would def recommend him and his company to others. Thanks again Adrian 👍

Bought a second hand bmwx1 from dealer. Contacted F5 to come and do full diagnostic check and carbon clean. Adrian came to my home and did the work on my car and explained to me in a very professional way what was wrong with my car. I had the work done on my car but lots of things continued to go wrong that would not show on a diagnostic check. I was forced to ask dealer for my money back and Adrian at F5 helped me with reports to achieve this. I would totally recommend F5 they go out of their way to help and their knowledge of the work they do is outstanding.

Had this service done to our Mondeo Mk3 V6 today by a professional and very knowledgeable man. It took him around an hour to complete the clean and the results are amazing. With the age of our car I didn’t know what to expect but I can honestly say that it has given our car a new lease of life. The acceleration has improved immensely and it now feels more responsive and quicker than it did before the Engine clean.. well done and many thanks, I now know where to come if I need another car doing. Worth the cost and will definitely recommend to my friends and family.

Great service as always. Peugeot 508, had a small blip on acceleration and lightly rough idle. Diagnostics feed back highlighted a couple of potential concerns, nothing major but a couple of jobs to do. However, after the carbon clean I now have a car that idles, lovely and smooth ( and quieter) and drivers smoothly through the range, better throttle response and no more 'blip' on acceleration! Very happy ☺️

We've used Adrian before so know exactly the first class service we're going to get. This time was for two vehicles, a new acquired Citroen Ds4, a few faults logged nothing major, but a good carbon clean to give the engine it's best chance for the future. Also same service on our modern classic XR3i, too old for diagnostics obviously, but after a carbon clean, better throttle response and a much smoother idle. Great guy, great all round service as always.

Adrian talked me through the engine carbon clean service prior to booking, so I booked the service and agreed a date and time, on the morning Adrian kept me updated on his ETA, and arrived promptly and on time. Adrian then got to work in a really friendly manner, keeping me updated on the work, and explained what I could and couldn't expect from the engine clean. Adrian ran a diagnostic test on my vehicle, and let me know what the test showed, then set about the engine cleaning. Adrian was very knowledgeable and had a great ear for the cars quirks. Towards the end of the engine clean it was a real difference in the sound from the engine, a lot calmer and quieter, and for its age seemed dto be purring great again. Adrian was brilliant throughout the service and I would highly recommend his services. All in all a great experience. Thanks Adrian. Will definitely be using them in the future.

2010 Kia Ceed 1.6 diesel 173k mileage. Failed MOT massively on emissions (test reading = 3.21 LIMIT = 0.8!!!!!). Spoke to Adrian and booked in for a carbon clean. Adrian arrived on time and was polite and professional, explained what was happening and why. Took the car back for a retest and got a happy pass with a reading of 0.1. Am more than happy to highly recommend this company. Many thanks

We have used Adrian many times and as usual such great service by this man. Explains everything about any issues etc. We've just had both cars done.. A Honda Crv and that had no issues and a Nissan Qashqui that was diagnosed with a thermostat on its last legs by Adrian's impressive diagnostic tool... Don't assume your engine temperature guage gives you accurate readings as you don't know what's happening under your bonnet. Both cars have been cleaned.. Alot quieter now.. More responsive on the throttle and alot smoother Definitely recommend Adrian... Top work as usual Thank you

I have just had my BMW X2 Engine Carbon Clean by Adrian of F5 (F5ECC) He was very informative and the job only took one hour, he notified me of any faults showing up on the Diagnostic test. And afterwards while driving my car, I could notice the improvements straight away, Money well spent.

After a narrow emissions fail at MOT for our 9 year old Land Rover Adrian was able to fit us in on very short notice. Booking was simple, and he arrived bang on time. Great customer service throughout, happy to advise and explain not only what to expect but also how to keep cars in best possible shape between visits. Would thoroughly recommend on every aspect of both service and results. (And yes, the car passed its retest)

Adrian was prompt on time and very knowledgeable, the cleaning process takes around 45 minutes with a free engine check service for codes and possible future problems that could be occurring. Now before this clean my car was running rubbish I must say and now after the clean, it's like brand new, no dipping when I accelerate, now smooth idle and no more nasty smells when on stationary tick over. So if your car is running rough, smelling and not performing well, then give Adrian a call, he will come to you.😉
