Barratt Homes have got into a pickle over the 0844 call cost  info see.

"Calls to 0844 numbers cost 7 pence per minute plus your phone company’s access charge.
*Call costs may vary depending on your service provider. Calls are charged at standard local rate from a BT Landline. Calls from non BT landlines and mobile phones will be charged in accordance with your tariff and service provider agreement. Please contact your service provider from further information."
