This line worries me. What other cost-saving have you done in this property that may result in safety being compromised? No RCD's because you don't want 'all those hideous switches' ?? Daz
This is going off-topic but since you ask, we have just installed a modern control box for all the power in the house. I do not know if it contains RCDs but it contains incredibly sensitive trips that will trip if it detects any anomalies.
