Just thought I'd throw my two pence in here with MTL, based in Marshland near King's Lynn, Norfolk.

They've done a sterling job over the long time they have been with the school, always happy to go above and beyond to get the work done. All the guys we have had from them know their stuff as well as the director who we see quite regularly just so he can keep up to date with whats going on in the school (and we have a build project he's involved with!)

They have installed all network cabling including fibres, VoIP telephone system (Mitel 3300) and they now do CCTV although we havnt had that installed (yet!)

Their website is: M.T.L. or if you want any more details, feel free to drop me a PM and I'll forward them onto you.

Oh and no I dont work for them!
