Are you in a superfast area?
If fibre-based broadband is available, the next step is to contact your chosen service provider to place your order .
Independent broadband comparison sites can often help you find the best deals. You could try cable.co.uk who are online and can also be contacted on 0800 840 5395. Other sites are available if you google broadband comparison.
Remember to look for fibre broadband and not standard or basic broadband (ADSL) which is what you may currently have.
