The Virgin Media router also has DHCP.
My Virgin Media has an option for 'modem mode' or similar that switches off DHCP. You can find this in the admin webpage on http://192.168.0.1
I use my own router behind it that provides DHCP and Wifi.
It appears it is a bad idea to have 2 DHCP servers but not sure
if this will
stop the tablets and smartphones getting a connection.
It's bad. You never know which DHCP server will respond.
Both will. The question is which will respond first. Apparently, one of OP's DHCP servers is faster than the other (at providing DHCP responses), and that is why all of the assigned host IP addresses are in its range.
(Presumably, once the enquiring host gets a response, it will configure according to that and ignore the other response.)
