Proud of our local community

We are proud club members and sponsors at Hitchin Rugby Club. Rugby is in our veins, and has provided untold amounts of joy to the life of Mark Tidey, company director, and his son, Tommy, who has served as club captain at the club and more recently has represented the England Fire Service rugby union team. 

We beleive in giving back to the communities we serve, and in particular Hitchin, Hertfordshire, which has a special place in our hearts. 

Reviews From Our Clients

We used to have problems with young “tearaways” at the end of our annual local festival which we tried unsuccessfully to address ourselves. We were all too tired by the end of an exhausting day, so we decided to try a security company – a bit heavy handed? Certainly not, they were able to quell the troublemakers by talking to them, but in such a manner that the boys (and girls) knew that Function Security meant business. We have had very little trouble for a couple of years now and we look forward to them being at our festival again in May.
Penelope Mitchell
Chairman of the Walsworth Festival, Hitchin. Herts
We have employed Function Security for our fairs, not because we have ever experienced any problems or behaviour that might be unwelcomed, but because in taking these few extra steps we believe it has aided us in keeping it that way. Putting on functions such as ours to which large numbers of the public attend places considerable responsibilities for public safety on the organisers, and using Function Security has provided us with that extra peace of mind in helping us to ensure this.
