Mark provides a first class service. Right from the point of contacting him, his response was prompt and professional. Mark not only recovered my data but also restored my computer in double quick time - picking up and bringing back my PC. Mark kept me in the loop about costs and progress throughout. His prices are very reasonable indeed. Overall, the service provided by Mark was exceptional and I would have no hesitation in recommending his services! He will be my first port of call if I have any IT issues in the future.

I stumbled across Insomnia a couple of years ago when I needed a new PC and my usual provider let me down what a stroke of luck. Mark is courteous, professional, knowledgeable, punctual and reasonably priced, the slightest thing wrong no matter how trivial and Mark will be with you usually the next day. The bonus is that Mark comes to you so no travelling to a shop backwards and forwards. He is also a super nice guy I can't recommend him enough I would not consider using anyone else now for any IT no matter how small.

Fast friendly and excellent service from Mark. My laptop was collected at 1.00pm and was fixed and back with me by 6.00pm. I would recommend Mark wholeheartedly to anyone needing a computer or laptop fixed. Very reasonably priced too. Thank you Mark.

Mark built my website for my Nanny business. I live in Tenerife and know Mark through a friend and the communication has been excellent for him to build my website and I am so happy how it turned out. He also continues to support me whenever I want any changes done to the site. I wish I could give more than 5 stars.

Mark did an amazing job saving our sons PC. We had written off the chip after quite a few pins bent when putting it in and resigned to having to buy another. Mark painstakingly straighten all the pins and fitted the chip and check everything was working. Such a breath of fresh air to find a genuine honest and trustworthy person. Excellent service and will definitely recommend Mark to family and friends.

Mark set up my laptop. He was extremely helpful & professional. Explaining everything as he went along in plain understandable language. If I had a question he took time to answer well. It was done on schedule & budget & I can contact him anytime for further help & advice. The best trader by far that we've had for any job. Thank you!

Called Mark out when i started having issues with my desktop computer he was polite and showed excellent knowledge in his field. Took only 5 minutes to diagnose the problem and after a quick order was placed he had my computer back up and running fully within the next 3 days. Thank you Mark should I have any problems I'll be calling you first.

Unfortunately my Applemac pro laptop developed cracked screen. I contacted Mark who advised myself on every issue involved. He kept myself informed and my computer was returned as good as new. I can sincerely vouch for his expertise, knowledge, reliability and more importantly his profound trust and integrity. Any problems I have in the future I will only and always deal with Mark. He's utterly trustworthy and his workmanship is second to none. It was like dealing with a friend you have known for years; as he is also one of life's genuine person. Great many thanks!

Mark helped me recover data from a dying hard drive from my laptop, not only did he get all my files but supplied and fitted a new drive, transferred all my files back onto the new one and set it all back up for me. When Mark left, all I had to do is put a couple more of my programs back on and it was like it was before I started having problems. Mark is a great guy, pleasant, polite and I would highly recommend. Thank you once again Mark. John (Eckington)

After building me a new computer last year, Mark has just paid a maintenance visit and reports that it was all very healthy with no issues at all. As always, he was thorough, efficient and, when I had a query about scanning photos onto my computer, he spent time with me going through the process. Above and beyond the call of duty!

Where do I start? Mark has put the "Trust" back into trusted trader for me, my computer was full of viruses and mark got the computer running back to like it was brand new, all my family photos were saved and he turned it around the same day. Highly recommend, and I won't be using anybody other than Mark. Just to let everyone reading this know, I had 2 other people come out and try and fix my computer and didn't do a very good job, and I have recently found out that they weren't legit businesses (Doing it on the side).
Mark gives peace of mind that he is a Derbyshire Trusted Trader (this is where I found him) with amazing feedback and I can see why. On a personal note, he is a very nice guy, polite, and clearly knows what he is doing. Thank you Mark.

Just want to thank Mark, really nice guy, he did a fantastic job on my home business server which I use for my Joinery business and I can honestly say he saved me from weeks of recovering from losing work files. Not only did he do an outstanding job getting my files back but also gave me great advice in regards to backing up. I certainly wont be using anybody other than Mark for future computer problems. 5 Star all day long.

Used Chesterfield Computer Repairs for what seams an eternity now not only have I had them custom build the systems I have (at very reasonable prices) But have had repairs done on my laptop and even had cover from them for virus and spyware removal after my on-line banking was compromised. Fast, Friendly, Reliable and knowledgeable are just a few choice words for this company If they cant sort it on site they will offer to take away and have it delivered back at a day and time that suits you. I recommend Chesterfield Computer Repairs to anyone that asks for help when it comes to Computers.
