On 17 July, for 24 hours only, the Carsons are going without power: no electricity, no gas, no petrol. And nothing with an 'on' button. We're not totally sure yet how we'll cope without a cuppa, but the money we raise by taking part in Off the Grid will make a real difference to families in crisis. Tents, ShelterKits, cooking equipment, solar lights, hammers, rope and water purification units are just some of the things your donations will provide.

You're never powerless to help, so please spare a pound or two to help families in desperate need.
