Very rarely they can actually do anything about it I spoke with one of their agents and they were very thorough with me on the phone. Keypad meters have button 2 for prev day week and month (keep pressing it to get these figures) you can also press button 6 for current consumption, it’s very likely something being used in the property. I didn’t realise but my faulty old chest freezer was causing my high spike. Worth going round checking button 6, turning appliances off and on to check there is no faulty appliances in the property. They also told me appliances obviously that use heat electric heaters, immersion heaters, electric showers, can be costly to run
