Filling out EIC tick sheet

[Pete999]

Yes it's a panel heater, the rcd spur was installed next to socket and and heater supplied from this, but what you are saying the whole existing circuit must be brought up to current regs.

Depends on how it was/is wired, are the cables buried less than 5mm from the surface of the wall

The rcd protects the modified part of the circuit from the rcd spur point to the flex outlet in the bathroom, so this is correct?

Yes but are the other circuits rcd protected in the bathroom or have supplementary bonding in place?

Only his installed cable need to meet that requirement not the existing circuit

What cables Pete, the existing or newly installed, the spur point is in the skirting board next to the existing socket wired as a 15Amp radial in twin and earth (big old farmhouse) basically goes straight through wall to the outlet.

No and no.

It seems like my tradesman should have highlighted these issues, I just want to know myself what's right and wrong.

Here's another one, when filling out a minor works for the addition of a panel heater (in a bathroom) spurred off a socket, socket supplied with rewirable fuse, RCD spur point then through the wall to and flex outlet, is the overcurrent device for the modified circuit the 1362 fuse or the rewiriable fuse?

Also Where bonding to water or gas/oil is not present must this be installed in order to complete the minor works?

Your work needs to be compliant so the heater circuit needs 30mA RCD protection as it is a bathroom, this is covered by the RCD spur.
The circuit from which you are working and the supply needs to be suitable for the load being applied and safe for continued use but not necessarily compliant with current regs assuming a 15A radial in 2.5/1.5 and a <2kW heater then it should be OK.
If the cable from the socket to the RCD spur is buried <50mm in the wall then that should also have 30mA RCD protection, but should be OK if the socket and spur are in contact.
The protective device for the certificate is the BS3036 15A, if the socket meets the disconnection time but the heater does not then the part of the circuit after the RCD spur can be protected safely by the BS1362 fuse, I would note this on the certificate if it were the case.
Earthing and bonding for the installation must be adequate for the protective measure applied i.e. ADS, therefore the main protective bonding for extraneous conductive parts should be in place and suitable.
You have increased the risk by installing an electrical item in a bathroom and there is some consideration that since there is not 30mA RCD protection to all the circuits in the bathroom that supplementary bonding for the bathroom (or 30mA RCD protection to all circuits in the bathroom) should be installed, but I would not usually do this unless the job were part of larger works.
