Careful if you're thinking of fixing.

 If you take it now then you effectively lose 1 month of the cheapest rates (ie before Aprils Capped increases)

It takes 17 days for a switch to go through. You'd lose a couple of days, at most.

I didnt say anything about switching supplier. 

A tariff switch with same supplier takes 24hrs max (four I did with eon yesterday were instant)

Some suppliers will agree to activate the new rates after a delay though - we’ve had confirmation of a fair few folk managing to get delayed starts.

Every decision is gamble to some degree. I took the eon 2yr fixed, a hundred quid above April 1st capped rate. (standing charge) per year. Plus I lost a month's much cheaper tariff.

I might regret it, but I can see a big increase in October. Followed by possibly 3 month interval changes to the capped variable rate. 

If you phoned them rather than doing it all online they allowed you to take the 2 year fixed rate but defer it til 1st April. Might be worth a call to them.
