As MrSaffron says

Your employer doesn't seem to be making a lot of sense here, or is there anything you haven't told us? What is this connection going to be used for? Because as well as speed there is the question of how much is to downloaded and uploaded. Many ISPs charge by the amount.
Did they mention the upload speed? Or just the download. It's quite unusual for downstream speed to matter a lot for work use within the UK unless huge amounts are to be downloaded, and that would be odd if there isn't much to upload.
We still need the output from what BatBoy asked for. Without it we have no idea what speed you can get, and that affects what we recommend.
