I would recommend CSS to friends and colleagues

Dr Mckean, Alva

Your service is prompt and efficient.

Mrs Melville, Bishopbriggs

CSS have provided an efficient and effective service for me over many years. Their staff are obviously well-trained and unfailingly cheerful. I wouldn’t hesitate to recommend this company.

David Christie, Edinburgh

Have worked with this trader for the last 5 years in my capacity as an engineer at Midlothian Council. They have performed admirably over these years. I have found Allan and all his staff/engineers to be knowledgeable, helpful and courteous. Completing works on time to my satisfaction.

John Blake, Edinburgh

CSS then delivered a first class solution and service before, during and after the alarm systems were upgraded. Their engineers even worked into night to make sure everything got finished on time. We are very pleased with the upgrades and would recommend CSS.
