Dimplex - experts, fast and friendly service

CJS and the team got my new storage heaters up and running when the original contractor couldnt. I rang them and spoke to Chris and he was fantastic and offered initial advice over the phone followed up by sending a technician out.
Super service, they were here yesterday and bingo we have heat again!!!
Plus they are all so friendly to deal with - strongly recommend

Excellent service

I was very impressed with CJS electrical who fitted my Tesla home charger. Chris (the MD) came for a site visit on the day I initially made contact to discuss installation options, the types of available chargers and the electrical protection needed. I exchanged a few emails and had a conversation with Chris before deciding on the best option for me. Gareth was the engineer who fitted the unit and the earthing rod. He did a great job, leaving a very neat and tidy finish. Finally, Chris came back to check everything was working to my satisfaction. Both Chris and Gareth were friendly and very professional. I would highly recommend CJS electrical.

11 out of 10

Couldn't give higher recommendation absolutely fab. With coronavirus plus Easter thought would be a nightmare to get any help with my aunties electrics but they talked me through everything on the phone to save paying call out charges Chris was brilliant as said highly recommend and thank you.

First class, professional, caring service

If I could give a higher rating I would! There aren't words to describe how grateful I am to Chris for his professionalism and his help.
In the midst of the Coronavirus lockdown and being over 50 miles away from my 92 year old mother a phone call telling me her cooker had stopped working was the last thing I needed to hear. I phoned Chris for advice to decide if this situation met emergency criteria and it was a huge relief to know that an engineer would be able to call to ensure that even if the cooker didn't work, at least mum would be reassured that all the electrics in the house were actually safe. It was very reassuring to have all the additional safety measures that would be put into place for this visit explained so carefully in advance so I could prepare mum to know what to expect. Fortunately it wasn't serious but the peace of mind I now have knowing that mum is safe and that she no longer has to worry is priceless.The fact the cooker is now working was an added bonus!

Saved me an expensive emergency call out

I've always used CJS electrical whenever I've needed something done but this weekend they went above and beyond for me. Having my electrics go off on a Saturday night is less than ideal and I called CJS expecting to have a very expensive weekend call out. When I rang, Chris was amazing at talking me through potential issues by asking me to send him photos via WhatsApp. He managed to resolve the issue remotely completely free of charge! Thank you CJS!
