One of our governors runs a technology company locally. He supplies all printer cartridges to the school and, despite repeated attempts over 4 years, I have yet to get them ordered from anywhere else which would save us a fortune.
He quoted for an installation job in a new building, but didn't itemise the quote which was expensive. The then Bursar and I weren't happy and asked for an itemised quote so we could compare. He wanted us to show him the other quotes. We refused, he did itemise and, on this occasion, I won and the installation was done by someone else.
The original installation was done just as I arrived here. I had no say in the spec. The equipment supplied by the same person has been a PITA and expensive. In some cases (e.g. the switch cabinet) the wrong things were supplied and we had a lengthy fight to return and exchange for the right items.
It really riles me. I'm a governor at another school and the register of interests alone would stop this there.
