1st bill is typically generated a few days after it goes live, that first bill will be slightly higher than normal, this is due to BT billing in advance, so you'll have the few days between going live and the bill generated, then a month in advance plus any activation/setup or postage charges, once generated the payment is due around 7 days later.
Month 2 will be the normal price you agreed when you joined.
