  • I would recommend this business

Had two laptops repaired with Mario. Both needed new SSD drives and one had a new fan fitted. Both were dealt with quickly and expertly. Very friendly service, good communication and a fair price.

I have nothing but good things to say of Mario's work. I've gone with problems for a number of Macbooks for me and my family over the past 6 months and mario has fixed then in each instance.

Often Mario has spent hours identifying the problem and then finding the best solution while also pricing his services very farily.

Keep up the good work Mario!

Apart from the quick response to the job, Mario is very honest and very accommodating. My desktop was fixed very quickly, and as a bonus I purchased a laptop from him at a very reasonable price.
I highly recommend this lovely chap, and If I have any computer issues will definitely visit him again.

Mario worked on two computers for me, a pc and Apple. He was very professional and dealt with the issues in a timely manner. It is always a risk going to someone you don’t know to fix these sorts of issues but he did a great job for me and I have been recommending him to friends as a result.

After looking for someone fairly close but, most importantly, highly rated, I engaged Mario to diagnose the slowness on my IMac. He's now switched out the hard drive with the more powerful solid state version and what a difference!! But just as importantly was the excellent communication, fabulous responsiveness to my questions (I am not an IT expert), clear expertise and genuine niceness of the man! If anything goes wrong with any of my or my wife's computers, we'll so be going back to Mario. I can't recommend him enough.

Excellent service, very easy to understand for a computer novice like myself, fast turnaround for what I needed and came recommended to me!
I thought my old macbook Pro was a total lost cause after being told by a shop professional that nothing could be done - last year Mario gave me back a full working computer at an excellent rate. Just now I had a query and he replies super fast! Thank you!
Highly recommended.

Customer Testimonials

Perfect service! Thnx for repairing my laptop


Mario was able to pickup the PC on the same day I made the call and the following day it was fixed and retunred. Good coverage and preparation if any further issues occur as well. Would highl recommend.


Brilliant service- Mario picked up my laptop on the same day I called and dropped it back as soon as I was available to receive it. He replaced my corrupted hard drive and transferred everything over to the new one for me.


Mario enhanced the wifi signal in my house with a booster which he kindly sourced. I now have signal throughout the house and into my garden which is a amazing on summer days.

Mario has helped us on numerous occasions fixing laptops and giving advice. There is no end to Mario's talents - he even entertained the dog doing roly-polys.


We had an issue with security on our computer for the initial call out. The service was beyond amazing. Mario, who helped us, was incredibly nice, was really fast in responding and helped us with any questions and queries we had. He checked all our accounts to remove malicious software and updated our security and gave up useful information on how to stay protected in the future. Alongside the general amazing service he also notified us on how slow our network was and personally spoke to our current network for us and upon realising that we couldn't do better with our network he took it upon himself to look into other networks that we were interested in and advise us on the best network for us in our area. We couldn't have asked for more and would use his service again with out a doubt. If you don't use him your losing out on an amazing service. Thank you Mario :)


Had a problem with my daughter's laptop, they picked it up and returned it for a fixed fee. It was returned two days later and working perfectly and at a reasonable price. The price I was quoted over the phone was the price I ended up paying. Excellent service and customer care. Very very happy. Highly recommended.


I needed IT help that was more bespoke and communicative than the usual high street service. This was received. Would highly recommend this service to others. Especially the small business or sole trader.


Have been looking to update our computer for sometime. I've used Marios in the past and have always found him to be reliable, professional and probably the most tech savvy person I've ever met. Unlike other computer techs I've come across who treat you like an idiot Marios explains everything in easy to understand language and leaves you feeling content that a good job has been well done. His prices are very competitive too. Highly recommended


Thks again for sorting this out Mario. Another problem resolved quickly and efficiently by ComputerworksUK. So nice to have a local firm to rely on for all my PC issues. Mario's a very knowledgeable, trustworthy and very good value.


What a great service. Mario is a dedicated and helpful guy. Knows his stuff. My mac has never been so fast.
