In Carnforth, Lancaster and Morecambe, it has been quite a mild winter compared to
previous years. You may have put in loft insulation, but the wiring creates heat, more so within insulation.
The heat reduces the amount of electricity the wires can transmit to sockets, lights and any other device on a circuit, and the heat can also damage the wires.The wires may need to be replaced, and it can be expensive to do so.
You can help this problem by creating space around the wires or laying the wires along a wooden block outside of the insulation.
