Insuring business office contents

[JNMann]

Having just set up my company I am about to move into new office premises.
I need to arrange contents insurance to cover equipment, i.e. computers etc. and also stock.
Can somebody recommend a company that can arrange this contents insurance for me?
I've looked at a few but they seem to offer far more than I need, the office is within a large building that houses many companies.
Many thanks in advance!
