We are looking at uprating the electricity supply to our Caravan park and it looks as though we need 200 kva 3 phase but the shock of the installation cost the real surprise was the suggestion that we would have to go on half hourly metering with a monthly standing charge of £1 per kva (£200) per month!! Is there any way around this? Because we are rlacing and consolidating three existing supplies (mixture of single and three phase) we could put in two smaller supplies if it helped. The installation costs would not be much more. £200/month is a bit excessive !!
