EICR Results C2 Smoke alarms?

You only have to have interlinked wired alarms in HMO’s. The battery ones you have are fine. Not that it’s anything to do with the tester as an EICR doesn’t cover those. The undersized main earth and bonding is wrong. The sockets, unless broken, don’t require changing. These items could have been a C3- requires improvement.

An EICR only covers requirements from BS7671. Smoke alarms are BS5839. Get a fire alarm specialist to test your system and provide appropriate certificates. They will be able to advise further. As far as I’m aware your are required to have a number of hardwired interlinked detectors in certain areas. For the sockets, BS7671 requires BS1361 compliant sockets. The circumstances in which a switched or not switched socket would be compliant depends on the use. For example a socket for a integrated appliance doesn’t need a switch but one in a hallway does. The other requirements for sockets having switches come from Part M of the building regs but they are nothing to do with an EICR. For the conductors, I would ask them how they came to the conclusion about sizing, it is very rare they are undersized when calculated by equation rather than tabulation. Sounds like you’ve had an inspector who’s abit unsure of the regs. Yes you can use another electrician, in fact it is recommended to use different electricians for reports and repairs. It helps to ensure an impartial inspection. Edit- Carl and Deacon are correct about battery smokes.

The inspector is talking boll***s... 1. Why is the earth conductor undersized? Is this by selection or calculation? 2. MPB conductor undersized? Again, how so? What system earthing arrangement is it? Any signs of thermal damage at BS951 clamps? 3. C3 if anything, or an N/A. 4. As ELX stated, we inspect and test to BS7671 2018, not BS5839-6. However, if one were to see issues with compliance regarding BS5839-6, one would make a note. You have an existing house, with existing battery smoke detection. There is no requirement for you to install wired detectors. If it were a new build project, that would be a different matter altogether. What is imposed on you as a landlord is that those smoke detectors are kept in working order and a maintenance program is in place to check that they still operate and the batteries are updated. This is normally an annual thing. Good luck, Carl.

Did the guy testing know BS7671 2018, I don't think so, what everyone has said above is true, You can use anyone you like to get the works repaired, your chose. Did you pay him???? All the best Kevin
