Hi All - I’m trying to temporarily retrofit the broken ballcock mechanism for my (very) old toilet cistern (needed for 3 months before sufficient money is available to revamp the entire bathroom). The vertical inlet pip can be seen in the attached (the white pipe on the right hand side. Does anyone have any ideas on the modern parts that could potentially retrofit this cistern? Thanks!

I always keep a few of these handy. They fit the vast majority of bogs. Not had to return to one yet either.

A Torbeck valve, whilst not always the most reliable type of valve long-term, will fit just about anywhere, even in slim cisterns like yours. Bottom entry type is required. If you're revamping soon-ish and want to guarantee the cistern walls will not interfere with the float, I'd be fitting a Torbeck.
 
I'm a fan of these:
They fit into quite tight spaces and work really well. Get from somewhere that allows returns (e.g. Screwfix) and measure it up carefully before attempting to fit to confirm whether it's suitable.
 
I'm a fan of the Fluidmaster too but that cistern really is tight, especially with that "indent" running down the corner of the cistern. Whilst Fluidmasters do fit in most spaces I'd think there was a fairly good chance that protrusion will interfere with the float despite the "back side" of the float not protruding far.

By all means give one a go if OP fancies it but I suggested the Torbeck because it is guaranteed to fit.

The Fluidmaster is a better valve overall though I agree.

I am sure I have fitted a new version of this cistern recently. Speak to somewhere like Wolseley or city Plumbing. The new parts may work with the old cistern.
 
All - thanks for great input. I’m going belt and braces and replacing the old valve with a identical one from ToiletSpares.co.uk. Thanks for spotting the Fordham model👍🏼👍
