Before letting your property it needs to be safe for tenants, you need to check the electrics or have it professionally checked.
Unlike gas safety you do not need a certificate, but they electrics need to be safe,
Make sure your rental property's electrical system has been safety checked. This will check for wear and tear, damage or other issues:
Make sure your fusebox (called the ‘consumer unit’) is fitted correctly and not damaged. Also make sure it is not obstructed with flammable things like paint, newspapers or cleaning fluids.
Check there is an RCD (Residual Current Device) and it is working.
Ensure cables aren’t passing through doors/window openings.
Check sockets are not overloaded.
Before plugging in leads/cables check for signs of damage like cracks and splits.
Check relevant covers are in place and undamaged on appliances so shock or fire risk is reduced.
Make sure on every floor a smoke alarm and a carbon monoxide is fitted, working and the alarm sounds when tested.
