Diamondsource Reviews 

Excellent service from start to finish. I logged the issue and they were out the very next day to repair our printer. The engineer was knowledgeable, efficient, and explained everything clearly. It’s rare to get such fast and reliable support — really impressed and would definitely use them again!

We had a very disappointing experience with Diamondsource regarding a repair on our OKI 9541 printer.

The issue we reported was a persistent paper jam error, despite there being no actual paper jam. An engineer was sent out in mid-February and diagnosed the problem as a worn multipurpose tray (MPT) roller. Based on their assurance that this was definitely the cause, we agreed to proceed with the replacement — even though we had doubts, given the machine had only produced around 4,000 copies, making such wear highly unlikely.

We were charged significantly more for the part than market rates, but were advised that sourcing it ourselves would incur additional engineer visit charges. Trusting their expertise, we proceeded.

Unfortunately, the issue remained exactly the same after the replacement.

Following further engineer visits, a second engineer later confirmed that the problem was not the roller at all, but the multipurpose tray itself. It is worth noting that the roller we were previously charged for is part of that tray assembly.

When we raised this with Diamondsource, they refused to issue any refund for the incorrect diagnosis and part replacement, claiming the roller is not part of the MPT tray. We were then asked to pay an additional ~£300 for a full tray replacement — again, without any guarantee that this would resolve the issue.

To date, we have spent over £400 with no resolution, despite being told that their work is guaranteed.

Overall, this experience has been extremely frustrating:

Incorrect diagnosis leading to unnecessary costs
Overpriced parts
No accountability when proven wrong
No clear solution or guarantee moving forward

We would advise others to proceed with caution and seek a second opinion before authorising repairs.

I got immediate attention to my problem with my computer printer. Excellent and friendly help came same day. I then also got very helpful advice and backup to resolve my problem with the printer again same day.
I will happily and unhesitatingly use their service again.

Saif has always been extremly helpful and we always receive excellent Service!

Had major reservations about the business model of paying in advance of the engineer's call but I need not have worried.
The engineer did an excellent job - resolving one substantive issue and explaining what would be needed to resolve the other one (a new part but we judged that unnecessary). Also impressed by the follow up from the company about options opened to us. Would recomend.

Saif responds quickly, is very helpful and gives a good service.

Great technician. Expertise very good and pleasant manner. Quick work.

Diamondsource reacted quickly and sent an engineer. He was efficient and courteous. All in all a very good experience.

Excellent service, especially from Saif! Since discovering DiamondSource we have switched to using them for ALL of our company's printer servicing, troubleshooting, repairs and even supplies. They are top of our list for good reasons - including superb service, prices and expertise - and we highly recommend them!

Excellent service from Saif after current printer was determined beyond economic repair and recommending a replacement that meets our needs.

Excellent support - toners at competitively priced and very rapid delivery - over night

Do not use this firm. We had a relationship over a number of years. Sold us the "perfect" option for our office. The products were subpar so we complained. We were told there was nothing to do and thank you for trusting us but good bye.

Saif Ramzan is a very helpful person he goes out of his way to make sure you have everything you need, if you need anything from Diamondsource he is your guy

Chris the engineer knew what he was doing and reprogrammed some software on my Canon Pixma printer to extend its life.
Prompt service and clear pricing. Many thanks

Diamondsource have always helped with our company's toner and paper supplies. They also serviced our printer. Saif has been very helpful and prompt.

Lifesavers, we had been without a printer for a month until I found them, thank you for an excellent service!

Mr Saif Ramzan was extremely helpful in advising that my 10 year old printer a HP Color Laser Jet Pro M252dw could still be used connecting via a pcl driver to Windows 11 on a new desktop computer. The printer worked with Windows 10 but is not supported by Windows 11. Although not a new printer, it is extremely sturdy and of very good quality. The toners are still available for purchase and I will always support Saif and DiamondSource. Invaluable help.

Sincere thanks Mark Carlisle

Always great service, friendly, knowledgeable and good attention to detail.

Phone answered by real person; appointment booked; technician phoned on day with his ETA; very good experience and my elderly photocopier which I thought would be unrepairable is now working properly again. Brilliant.
