Crystal Sigma work at our property Crystal Sigma have carried out a number of installations for us at a residential block we own, including in line electric boilers, air source heat pumps and general heating and plumbing works. Their work has always been excellent, the premises left clean and tidy, and their response time and flexibility also excellent. We continue to use them for all our future needs related to the above

Recommendation I recommend Crystal Sigma

Very clean install in newly refurbished house Samir came up with the ideal solution for my house and Vali and his team did an impeccable job with the install. We were concerned as our house was recently renovated and AC was an afterthought, but Samir and Vali fit the system in a very clean and discreet way. We thought an AC install would be a large project and cause a lot of disruption but that was not the case with CS - highly recommended.
