Bluetooth shares the 2.4 GHz ISM band with other household devices such as cordless telephones, wireless networks, baby monitors, and microwave ovens. If you see issues with your Bluetooth devices that you suspect might be due to frequency congestion, see AirPort and Bluetooth: Potential sources of wireless interference for further information.

Had been through all in the apple : Potential sources of...... but without any success. Have now done a Mouse Factory Reset. Pleased I had purchased a nano mouse first ( like a wire mouse without a wire working from usb with small nano tx £6) as it took some time for the Mouse to reconnect. Would like to Factory Reset keyboard as well, but not sure I can restart Mac without spare wire keyboard!? Time will show.....
