There is no legal requirement to replace sockets if they are positioned on skirting boards in an older property but given that the wiring installation is likely to be old, it is advisable to get a registered electrician to carry out an inspection of the electrics

There is no legal requirement to replace sockets if they are positioned on skirting boards in an older property but given that the wiring installation is likely to be old, it is advisable to get a registered electrician to carry out an inspection of the electrics. They will issue you with an Electrical Installation Condition Report (EICR) which will either confirm that the installation is safe or highlight any hazards that need to be addressed.
