Losing a load of money with nPower during a long painful switch!
I applied to switch my dual-fuel (Electric and Gas) from eON to NPower early December 2012, after many chases with no correspondance I finally had a welcome letter in March 2013 from nPower, but noticed it was for electric only!!
After many more chases I was told they had computer system problems after a change to a new system and the gas was "stuck".
They quoted another 40 days to get the gas online!! (still on-going today).
That would make it over 4 months to get me switched! In the meantime I have no dual-fuel discount and my gas is still with eON on out of contract prices!
I am losing a load of money on this switch and wouldn't recommend NPower at all.
