The 0800 970 2070 number is sometimes unobtainable from my BT line.
0844 804 4999 and 0800 970 2070 answer with exactly the same IVR, as does 0870 992 0704. This 0870 number might be of use to someone with inclusive calls with BT. Come 1 August, if it's still in service, it will also be of use to people using providers who reduce call charges to those of 01/02/03 calls.
Steve Connor's number is the one before his PA's: 020 8150 8860
