I went for a job with CES about 2 years ago. I didn’t get it, but now looking at how things turned out with them going into liquidation and the really heinous customer reviews, I had a lucky escape.
Typical of companies like this, they always appear where there’s government grant money to be had. As soon as there’s a sniff that the gravy train is coming to an end they’re gone in a flash. They made £25 million last year so they were in a very good financial state. They knew exactly what they were doing by pulling the plug now.
Feel sorry for anyone who has historical or ongoing issues with them because the reality of the building industry is, you’ll find it next to impossible for anyone to take over their work. It’ll be a rip out and start again.
