Do I need a new circuit in my kitchen? (Ed.)

[Murdochcat]

TBH if you’re having a renovation on your home you should probably seriously consider if a full rewire should be undertaken

After all your OP does say you want to future proof

When adding another socket the connection is called a "branch," not a "spur," because the circuit does not form a loop. It does say it in the regs but it's best to avoid confusion.

That's what most of us (including me) say, and its certainly true that radials, and branches of radials, can branch as much as they like (using the same size cable for everything).

However, by sort-of analogy with spurs from ring finals, I personally DO usually use the term 'spur' to refer to a 'branch' from a radial with reduced CSA cable feeding just one socket - like the 2.5mm² 'spur' from a 4mm²/32A radial illustrated in Appendix 15. - but maybe that';s just 'me'!

Nope not at all - a radial taken from a ring is a spur. a 4.0 T & E having 2.5 spurs is OK too.
If a say 2.5 radials runs from fuseway the to points 1 to 10 and some of (or all) of those 10 have branches then are they or are they not spurs? I can see both viewpoints on that one. and when we get to number 10 on the end than add a spur/branch then does that point then become the end one of an eleven point radial rather than a 10 point radial? I`d say so , you could make a radial any topology by branching into "trees" at an or all points including at the fuseway, so it does get confusing sometimes methinks. consider what railways migh consider spurs from main lines might be one approach I suppose.

Anyway is it as confusing as the bloke who said that everything could be categorised until some wit suggested a library containing indexes of books by section then indexes of indexes then indexes of indexes that listed themselves then indexes of indexes that did not list themselves then where to index the last index the indexes both main indexes? Blimey, is life not simple Ha ha ha

"Ask what brand CU they will fit! That will give you an indication! Will it be all RCBO ?

Go on ebay, and see if you can find any MCB's that look like your current ones, and if they are available in 20A or 25A(rare)"

Will I be able to fit this myself?

No.

thank you everyone for the prompt replies. I will see what the best is because there is already a lot of mess going on because of the reno. i dont want more dirt around the house.
