Business broadband & Telephone

[MrReg]

Moving into a new office at the end of March and will require broadband and a couple of lines coming in (other lines via voip so will need to be decent speed).
Location wise it's saying normal broadband would be 17MB down / 1MB up, business fibre being 80MB down / 20MB up, and Virgin offering 76MB down.

Any suggestions to providers?
