Complex Systems was founded in 1996 originally as a software design company. We provided Consumer Credit Management Systems to the finance sector and developed POS and Stock Control software as well as various other projects including webdesign.

In 2003 the company concentrated more fully on support providing hardware and software services to business and residential customers.

In 2004 the company became a limited company and in 2005 we moved to a retail outlet in Tewkesbury. From here we continue to provide hardware and software services as well as being stockists of all major components and peripherals. We also still provide web & email services.

Our speciality is in PC & Laptop Repairs right down to component level repairs providing customers with a clear charging structure so that they know at the outset how much the repair will cost.

We were (as far as we know) the first company to offer 5 Year Parts & Labour Warranties as standard on all our PCs from 2005 and from 2008 this became another industry first changing to a Lifetime Parts & Labour Warranty on all our PCs. We believe passionately in our high levels of support and expertise and the Lifetime Warranty reflected our committment to making IT and us as a chosen support company - a simple one!

Customer Testimonials

Had to have the keyboard replaced on my laptop due to water splashing on the top. Complex systems diagnosed, ordered the parts and repaired it in 4 days and kept me informed via text/email throughout. After the diagnostic test they inform you of the cost and have the option to pull out if you don't want to go ahead. Although I do not have a great deal of experience regarding computer repairs, I thought this was repaired at very reasonable price, I believe they are trustworthy and I would not consider going anywhere else. Plus you receive a free gift on collection and who doesn't like a freebie!!

Had my laptop repaired here more than once. Have found the service excellent. Quick sound advice, problems permanently resolved bythe expert technician. Will always go back for all my device problems.

This is the 2nd time Steve has saved me regarding Windows 10 update. I explained that I had important data I needed to save and he took a note of all things I needed saving. I was kept informed via text and email at every stage of repair. This morning I collected my repaired laptop and I'm up and running. I'm no technology expert but everything was explained to me and I'm so grateful. I am 100% satisfied and I would recommend Steve to anyone. There was a free gift I found when I got home too. This just leaves me to say a big Thank You

Repair to an IPad that would not charge. I found Steve very helpful and friendly. I collected the IPad the next day fully charged and working perfectly. The problem was a faulty charger. I felt the service I received was excellent and l was not overcharged for the replacement charger.
I would recommend him if you had a faulty phone, tablet or computer.

They certainly know what they are talking about. Totally professional, they listened to my explanation of the fault on Computer, and then I left it with them for any repairs that were required. Computer was repaired in 24 hrs, I was fully informed by the CSD Ltd for each step of the work the did up to completion. You just don't get Service like this theses days, it was a pleasure to be able to use them. I am 100% satisfied.
