Fibre is coming to our street in the next few months (physical works have started).

Is it possible to get the fibre connected and an ONT installed and continue to use broadband?

Or are the old lines removed when the fibre is connected?

This may seem like a silly question but ...

We want to take advantage of the subsidised connection, as we want to have fibre connected should we wish to sell the house 

We don't need fibre - ADSL is fine for our use.
