Is there any way around it?
With only limited exceptions, not really.
Virgin Media may be able to offer you a cable broadband service that operates independently of the Openreach network, but it’s only available in certain areas of the UK.
Alternatively, if you live in a large town or city, you may be able to benefit from certain niche suppliers such as Hyperoptic, who install and maintain their own network, but they are not yet widely available.
If you live in an area with very good mobile phone reception, there is the option to go for mobile broadband. Mobile broadband doesn’t require a landline and therefore there’d be no line rental to pay. However you obviously need to have signal to be able to use it, so might not be so great in rural areas.
Or you could look into satellite broadband, however the cost might still be more than paying for a broadband package with line rental – and the coverage and speeds could be worse.
