No, nPower are not the best it very much depends on your circumstances, try uswitch.com, they saved me several hundred pounds a year.

If you forget (Regularly) to do your washing etc in the evening and you heat your house through the day, economy 7 isn't really suitable and could cost you more than a regular plan.

Good luck

I live in a rented ground floor 2 bed maisonette.

nPower are my providers for both gas and electricity. Standard tarrif's.
I believe if I go paperless I might save??

I curently am paying £70 a month for electrity.
And £40 for gas but that is to clear a back debt due to them failing to input a reading from a meter man and then reducing my payments and giving me a refund of the credit I was supposedly in to only discover in November just gone, that I then owed £120.
I anticiapte it should not need to be more than £15 max a month maybe even just £10 to cover winter useage.
I have no heat in my bathroom so like in the bitterly cold psell this last winter the firre was on 24/7 on the lowest setting for a few weeks to keep the whole place a little warmer.
The bathroom was so cold (15C) that I went 4 weeks in between baths! (I did wash!!!!!)
I am hoping to persuade the landlord to install some form of heating in there, I do believe a msall sotrage heqater might be able to be used?
(The landlords are very good. They are a charity.
They installed a drive for me so I could have my car at the front door as the road I live on is fully parked up in the day- all day- by shop workers and I would go out and come home to find I had to park a long distance away and that was before I was able to get my wheelchair in my car. So on some occasions I was forced to sit in my car hoping someone would leave so I could park a bit closer to my home. But that is all resolved now. )

( I previously lived in a 3 bedroomed detached house and within 6 months of moving in to this place was paying the same as I had there overall on fuel! I was horrified!!
The move was on health grounds and the bank would not continue my mortgage because of my health and so I had to rent to remain close to my support network.)

I have been looking at other posts and the question on Economy 7 useage.
I seem if I have my maths correct to be using about 70% of my electricity at night.
This really surprised me.
Per quarter in the winter gone it was 4300 kWh in total, with 35000 at night and 800 in the day.

I have 2 storage heaters in my bedrooms, an electric immersion heater on a timer, ( 2 hours a day, morning in Economy 7 period the evening is not to allow me an evening bath) and a Gas fire only used in the winter.

I am disabled and very mobility imapired so I do feel the cold.
But I try to keep temperatures at 22C max.

1 heater is 10 years old, the other 2. But that room is little used so the door is closed and the heater only on 1 in winter.
Even so the newer heater a 2.5 kWh one in my bedroom where I can spend up to 70% of my time becasue of my health is never hot at the bottom at the end of Economy 7 hours.
And in this last winter (which I know was abnormal!!) was cold by 6 pm - I had to put extra heating and clothing on in an evening.
I cannot put too many layers on as that restricts my movement)

At night what is on are my 2 storage heaters, my bedroom one on max, the other on 1 in cold weather, the fridge freezer, the immersion for 1 hour, and one TV and Sky Box on standby as I cannot reach to turn them off.
( I may try to get a remote plug for them so I can turn them off- if they work!!- any opinions?!)

The other TV etc. and all other appliances are turned off when not in use.
I always turn lights off when not in rooms and have energy saving light bulbs in place.

There is an outdoor security light triggered by movement. But it is only coming on about 3 or 4 times a night for 2 minutes or so.

The maisionette is about 50 years old.
The windows are double glazed. 4 years in place.
Cavity insulation was installed about 2 years ago. I cannot say I have noticed any difference but the lady upstairs says it has helped her bills.
The window in my bedroom -facing north- is a massive 8 foot by 4 foot and I have thermal blinds and curtains (at all windows in the property) which are always closed at dusk.
And on very cold days only open enough in my bedroom to allow light in.
They stay shut in other rooms.

I am on benefits and find I am paying about 9% of my income on fuel.

So--
1. Is nPower the best supplier?
They have always been my electricity supplier but people say they are the most expensive.
They have a Special Needs section to ensure I never lose my electricity supply or else they provide alternative heating. And they sent me free light bulbs once!!
A fail safe so I am never cut off. So I would want a similar option with a new supplier.

2. Do you think the 80% useage is too high?
I always forget to run my washing machine and tumble dryer at night stupidly.
If I did it would be used 3 times a week max. (Cold fill)

Any ideas of a better supplier etc. would be appreciated.
