It is possible you may be able to ditch some if they serve no purpose but otherwise they need to shell out.
New board next to it fed from the existong would be his cheapest option

see if any two lighting circuits can be put into one breaker. sometimes the lighting circuits are split for convenience e.g upstairs and downstairs and it isn't always unsafe to put them into the same breaker. otherwise just tell him you want to do the job properly and if they arent prepared to pay for it then run away
Yea that’s the best option,will need to switch off & reconnect tails etc.
He’s not gonna be happy,work will either be @ night or weekend.
When he expresses his disgust with shutting down his site for works perhaps remind him that doing it properly this time round and installing a DB with many spare ways will prevent this problem from happening again in the future.
Edit:
Another option could be to consolidate a few 1P circuits into their own DB fed from the exsisting 3P DB. You could move 4 lighting circuits over to a 1P DB and have enough ways for a 3P MCB and 32A SP MCB to feed the new DB.

You are going to lash a new board off the live side of the existing one??
If you’re doubling up a couple of lighting circuits here and there, and maybe a single point spur onto a ring.... you’re going to have to reconfigure a lot of other circuits to get 3 together for a 3 phase circuit.
No bodge job, @cliffed Tell him it needs to be done right. Got to keep those phases balanced and all that.

Sub board off the existing board for me, not a henley block. Then move a few circuits over to the new board to make way for the submain breaker.

But you won't get discrimination unless you can get fuse holders to fit the existing board to supply the new board.
what is that a snakes and ladders ,one circuit only for that .
tell your customer he needs to pull a golden egg out of duck A77,if that board needs changing .

The OP only needs to install one circuit, if he can gain enough space for an MCB to feed a sub-board he wont need a sub-board!
I think it's rather silly to dismiss the idea of grouping together one or two circuits to gain enough ways, without knowing the loads/circuits involved it may be a perfectly viable option. There seems to be a trend on this forum of late to dismiss common sense solutions to a simple problem as a bodge, and advocate 'walking away' if the client wont pay for the perfect end product. Perfect is not always required as long as a solution is safe, compliant and keeps the customer satisfied.

Ah sorry about my post regarding a 13 Amp socket reread your post and it's a new 3 phase circuit that is required sorry if I confused the issue, my bad.
Agree,& that may be the logical way to go,I doubt very much the client is gonna be happy with the idea of a new Db & costs.
If we walk away from it,no doubt someone will do it.
All will be noted on the certificate,so will pass the onus back onto the customer.
well said tooth puller ,I could not say better me self.

Is that a different orifice to the duck's A55?

Not always, a very blinkered and unprofessional approach to only see one solution to a very simple problem.
Squeezing in a single phase circuit may be possible ?
But another three phase circuit ?
That's just crazy stuff
Tell him do it right or not at all !
after all if something goes wrong
then YOU wear the can not him.

Kinda agree,but telling the client & making an observation & written report,given to the client,he too has that responsibility ,& decision making.
Maybe no different from replacing plastic Db’s,or any other “grey area” regulation.
Wirepuller makes a good point,logic & a sensible approach may be the answer.

It may or may not be possible, neither you nor I know the configuration of the existing DB. But to dismiss it without investigation as crazy is just plain daft. There could be a number of MCB's feeding a radial with one socket on the end which could easily and safely be tacked onto a ring as a spur gaining a way. Who knows without checking.
Why is something likely to go wrong with a carefully tested and thought out alteration to circuits in an existing DB? You clearly don't have faith in your own ability to engineer a different but compliant solution to a problem.
'Walk away' is one of the most common phrases on here of late, is nobody capable of thinking of something different?
Apparently not.....We live in Little Britain World.........'Computer says no'......

There seems to be a marked difference in opinion on this thread than another similar one that I had argued before :
(Does this setup contravene any regs or is it ok? - https://www.electriciansforums.co.uk/threads/does-this-setup-contravene-any-regs-or-is-it-ok.167990/.
For the record, and you will see this from the other thread, I don't believe it compliant to lump circuits together. I asked the NICEIC about the relevant regs relating to this and they agree (albeit they don't write BS7671). My only regret is that I didn't come up with the three phase circuit argument on the previous thread! That would have nailed it I think.

You’ve been given the bucket of chum award for the ‘Most likely Bait Post’ of this Thread!
Congratulations, wear it well!
Edit - although that does look a lot like the chilli con carne I made last night!

Nobody is suggesting lumping circuits which should remain individual circuits together, but it is plain stupid to suggest a radial serving a single 13a socket would not be compliant 'lumped' onto a local ring circuit to gain a way. Of course 3 adjacent ways are required here, but my issue with this thread is that the option is being dismissed as a bodge without even knowing the configuration of circuits in the DB. Of course it would be a bodge with a cak-handed approach, but I'd hope a professional electrician could investigate the possibility of accommodating the clients wish for a compliant cheaper solution, and not just throw the toys out and walk away. Far from professional in my opinion.
