Products & Services

We repair and build all computer problems. We can upgrade computers or build a brand new computer system either to a specification or to a budget. We aim to fix all computer problems onsite hardware, or software related. If the unlikely event we have to take the computer offsite we will offer a fixed price and no additional cost for seting the computer backup once we are onsite.
We Offer 17 Years Experience, At Very Competative Rates


We have found over the years that nobody likes to have to unplug their system and carry it to a shop. As we like to be open and honest, not all jobs can be carried out onsite. This is not a problem as we can take your computer or laptop offsite to repair, and when we return we will setup the system back up so you dont have the trouble of dealing with it yourself. The technician will gladly answer any questions you may have and offer any advice needed.

Customer Testimonials

Mark is awesome, he came out to check my Computer as I had let scammers in by error and they nearly hacked my Bank Account . . . I was worried but Mark has sorted it all out . . . Brilliant, would recommend him as we have had his services for many years and have been totally satisfied! Mark is a great guy as well.


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.


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.
