Recently moved into a new home and we’ve had some trouble with loose wiring a few times. This time it was within the RCD. When the installation report was done by another company when we bought the property. They had left the main live wiring loose and exposed. The neutral wire was the same. David had arranged for one of his brilliant electricians to come over on the same day. Mark was able to restore power and heating to our home by rearranging and securing both wires. He explained the risks and processes fully. Can’t recommend them enough.
