electricity bill

I live in a house and my supplier is NPOWER. I would like to know how can I switch from BULB

I presume you meant TO Bulb?
Click in the ‘bulb’ icon top left of this page, and select ‘Get a Quote’.
If you have previous usage figures, go for the refined quote for a more accurate estimate.
It’s a gainer led process, so Bulb will handle the switch and inform n-Power.
