Client Testimonial
When we first met, I was still in hyped-up London CEO mode. Now, thanks in no small part to you and your guys, I spend my days in overalls and a bobble hat chipping away at masonry and planting veg! My goal in time is to turn the house and garden into a restorative, reflective space for women.
Onto the pragmatics, I am absolutely delighted with the results. I am still adjusting the fact we actually have lights and sockets after weeks with torches and extension leads everywhere. I will of course do an online review but just to say: as well as their very high quality workmanship, the guys were very sensitive and accommodating. The simple fact of keeping the shower wired up was massively appreciated. They even made sure to put in 'warm white bulbs' — very thoughtful indeed. Their communication was excellent both interpersonally but also in keeping me briefed.
It’s so rare to have contractors of their calibre around and we will genuinely miss their presence.
Thank you to you and to the Matts for your patience and flexibility, for recognising that it’s a time when I felt quite vulnerable and stretched, and for making the whole process positive and even a lot of fun.
Ceri and her team have just completed the full rewire and electrical upgrade of our 18th century farm house, which had been unloved and in disrepair for many decades. They also project managed the installation of a sophisticated solar battery system which is visually sensitive to the age of the property. I have been incredibly impressed by the quality of the work and, importantly, the highly professional approach of Ceri’s talented electricians. A full rewire inevitably brings some disruption, uncertainty and inconvenience but they made the whole process positive with minimal stress. Their communication was excellent throughout and we genuinely enjoyed having them around. They were very sensitive to our day to day needs and the impact of the project on the household (including pets!). What particularly impressed me was how up-to-date they are with the very latest technologies and techniques.
CTS are very established contractors in telecoms but I think that brings particular advantage for domestic projects. They worked both on the interior of the house and also fittings to the garden and exterior building. Ceri was an attentive, supportive project manager throughout and inspirational in recognising the opportunities to enhance our experience. I would not hesitate in using them again or recommending CTS to others.
