Lollipop or not?

[The Ghost]

I started installing a radial circuit in 4mm² singles in white 20mm conduit for an office. MCB=32a. T-N-CS

The client has decided to cut costs and while the builder is erecting a stud wall partition office he (the builder) will continue with the wiring. The builder wants to form a junction with the 4mm supplied to the office from DB in conduit and do a ring in the office. As I have to sign it off I say no continue in 4mm singles and make it a radial. However he is insisting on a ring circuit, making it a lollipop cct. I am tempted to say yes but did not, thought I would put it before my learned friends to garner some views before I answer him tomorrow.
So....what do you say?
CCT is circa 25m max radial by my proposal.

As Des 56 said test issue cert stating your work done /your liability and wait for the phone to ring when they have f***** it up.

Yep I am well and truly out of it, the builder is using his own system! Best of luck with that then. Tada!
