SPDs do i need to fit them?

[Ian1972]

Hi, I'm installing a new circuit in domestic dwellings for various housing associations my question is do I need to fit an SPD or would it be the responsibility of the housing association, the circuit supplies equipment in the garden I'm running a 2.5 twin and earth through the house fed from a B16 MCB or RCBO depending on the fuse board it goes to an external rotary isolator, thanks in advance for your replys

The housing association haven't specified any cable size, SPD or anything I'm just installing to the heat pump manufacturers requirements, regarding installing a SPD I'm not 100% sure if it's required or if even an risk assessment is required for a residential dwelling

If installed to amendment 2 then risk assessments for SPDs are no more.
The technical answer is they are to be installed where there is danger of serious injury or loss of human life, where failure of a safety service could occur, or there is risk of significant financial or data loss. In all other cases they should be provided unless the owner declares they don't want one.

How this relates to various jobs is something a lot of us are still figuring out. Obviously if it were a CU change you'd just do it.

You could cover yourself by asking "Do you want surge protection, as latest regs say you should have it?". If no, then add "Surge protection declined by owner" as a note on the certificate.
But if there was a spare way for a compatible 32A breaker, and room for a module, I'd just fit one.

If you can get a waiver signed by the Housing Association then you wont need to fit one, from the 27th Sept they are mandatory on new installs unless you have the waiver from the owner...whether new install includes adding a circuit is still not clear, will get back to you on that

Thanks for the answer as i understand its not really required in a domestic property but, as the houses belong to housing associations its not really a question for the tenants so would it be the housing association responsible for making the decision to install them in there property's as part of there electrical checks and maintenance?

I just want to make sure I'm covering myself incase something comes back on me in the future

I think in the 17th it wasn't required in domestic but it is now.

If its rental I assume there's D1 fire systems so it should be there for them as a safety service.

A risk declaration gives the owner the reasons
for having them so they are making an informed decision and documents their selection. It's allowed because significant financial loss or data loss could be seen differently from an individuals perspective.

The risk assessment previously was the calculation that calculates the risk, not a normal risk assessment.
