BT Infinity 2 for ~£16pcm (after they increased from the original “personal offer” of £14pcm for 24 months from summer 2016), plus BT landline paid in a lump sum of ~£208 for 12 months (means one month free compared to paying monthly).
We barely use the landline despite the free up to 60 min free calls at the weekend, but then we barely use our mobiles for calls either.
There was a deal recently by Plusnet which was quite attractive is you got rid of the free weekend calls. Well worth checking Topcashback/Quidco for nice deals for switching, we got ~£120 when we switched to BT a few years back.
So ~£33pcm all-in.
