Business phone lines

Frequently asked questions about business phone line installation

Common questions answered

What does the engineer need before they install a new business phone line?

The engineer will need access to your premises to see how much work needs to be done. They will check for things like previous sockets and connections.

Is there an installation charge?

If you're switching your line from another supplier, in most cases there isn't a charge as we'll try to use the existing phone line on your premises. However in some instances, e.g. switching from cable to BT or where an engineer visit is required, there will be an installation charge.

On all other orders an installation charge will apply - £99 on a 24-month contract, £106.37 on a 12-month contract.

If you need multiple lines, there may be a charge per line.

Can I change my installation date after I have ordered?

Yes. Simply call 0800 800 152.

Can I use the phone number that was in use in the office/building I'm moving too?

Yes, if the current occupier hasn't kept their phone number.

Can I move my phone line when I'm still within my contract and will I need to pay another installation charge?

Yes, you can move your phone line whenever you like. If there has been a suitable service in your new premises you won't need to pay an installation charge but you may need to if there hasn't.

Can I have a memorable number for my phone line?

We're unable to allocate specific numbers.

One way of getting a number that is more memorable for your customers is to look at our range of 08 numbers, you can also choose the number you want.

Can I keep my phone number when I move?

Yes, if you're moving somewhere on the same telephone exchange.
