You are better dropping any landline based service and looking at something like VOIP. if you send some money on a VOIP phone you can get a free landline number from www.sipdate.co.uk if all you use in incoming you pay nothing.
If you want to call out top it up with £10 or so and pay as you go.
I have a VOIP phone with 5 incoming numbers. I use them for online things. I know if i should answeer a call based on what number the call is on.
They give you an adaptor that allows you to continue using your existing landline phone. You can also install their app on smartphones & tablets & use your calling plan (and receive calls) from anywhere via WiFi.
