When the time comes for me to rent I will remove the electric fire. Makes it easier all round for me. And safer as these electric fires are quite unpredictable and can be unsafe.
The EICR is a straight forward process. You needn’t change your electrical installation, unless the Sparky tells you after the inspection that’s its not compliant with rules.
PAT testing is different. If your electrical fireplace has a plug, then i don’t think this would need to be tested as it is not a portable appliance if its fixed, however I’d check this with the sparky. If it does need PAT testing, then why not just swap out the plug for a hard wired switched fuse spur?
I have insurance through Directline and by chance I was talking to them about a renewal and they mentioned that there insurance requires a PAT on plugged items !
Not law but there policy.
If you you provide a fridge, freezer, washing machine, dryer or anything with a plug just get them PAT tested by the sparkie doing the test, it will cost you little at the same time as the electrical testing.
You may need your consumer panel changed and uprating of the protection. It’s good practice to get a panel with a slightly bigger capacity for any future additions.
Unless you intend to remove the lighting, plug sockets and all forms of electricity then you have to have an electric check.
If you want a successful tenancy then make your tenants as comfortable as you would want to be in your own home. Its a simple equation, you provide a home that’s safe and comfortable and the tenant pays you for that service.
