3C Test
"3S have been a fantastic partner during our recent expansion. They have managed the site, all the trades as well as being the electrical contractor during the fitout of our new 25,400 sq ft facility. Nothing was too much trouble even when we had to make changes part way through the project and this all happened during the coronavirus pandemic. I would recommend 3S as they are very flexible, friendly and you will get 100% value for money."
M&E Maintenance
