Im about to move into the house that I've bought and know that the previous owners energy suppliers were British gas , how do I check if I can get cheaper suppliers . 
I don't know the cost of the previous owners bills and can't seem to find on the comparison sites how to get quotes without knowing your annual or monthly bills

Use  average  .

Key is unit cost and standing charge .

PS   This is Oil LPG board.

Make sure you register with BG and send meter readings (and take photos) the day you take possession, otherwise you'll be on an expensive deemed contract.  Try 12,000kWh gas, 2,900kWh electricity; tweak up or down as necessary e.g. number of occupants, WFH or out all day, temperate or tropical, large or small house, terrace/semi/detached, insulation, etc.

Start comparing with Citizens Advice and 'Switch with Which?' and check whether separate suppliers are cheaper than dual fuel.

Send meter readings monthly, remember that fixed direct debit isn't All You Can Eat, and check that your DDs are sufficient to pay the bills.

You have posted in the wrong forum section but never mind.  You will get less responses but I think we can cover it.

Initially, go with a no tie in contract and go with an estimate.  Then monitor your usage and check again once you have a clearer idea of what your actual use is.  
In reality, the best suppliers for you won't change much if you are several hundred or even thousand out on your estimate.
One thing to be careful of though is making sure you are on an E7 tariff if that is best for you.     When we moved into ours, we used the same supplier initially for convenience and they put us on a non E7 tariff when E7 would have been better (and E7 was what it was before).  We got it changed within a couple of weeks but got hit hard for that two week period.
