There is a school teams group for discussing grant applications. Managing PhDs at Leeds Computing

There is a course you should take (Effective Postgraduate Research Supervision) before supervising students. This was vague enough for all faculties (e.g. humanities my only supervise PhDs once a month), so contained very little read information, I finally got a link to the university regs out of the supervisors.
There is another course to be an internal examiner (The Role of the Internal Examiner).
You should record PhD progress (i.e. once a month) in GRAD. GRAD will email you every time any action is taken on any student you are connected with - add an email filter and forget about it!
The "Engineering & Physical Sciences (EPS) Graduate School" minerva organisation has GRAD resources, additional course details (e.g. technical English), and a PhD student assessment roadmap.
University supervision resources here.
Simon Jones' video on how to write a great research paper
Eric Atwell can answer school-specific questions about the process.
When interviewing PhD candidates, Eric says "For future reference, when you interview a PhD applicant, the Gradaute Office standard interview form has a box "Bench fee" - this is where you can write "£7000 for essential consumables and equipment". to request a bench fee from sponsor, This is then included in the offer letter sent to applicant and sponsor. The sponsor MAY decline (eg HoS may say no for School studentships) so then at least you will know you dont have one. But they may just say yes."

Grants. Uni grant-writing-overview. For a financial details for a grant, email faculty research. They also like to know the outcome. I suspect we are also meant to tell Tony about past/present/future grants. You search/add alerts for funding using a site like Research Professionals (use Leeds account to login).

JeS. The grant applciation portal for EPSRC + a bunch of other research councils. It will automatically send your grant to the School's research team upon submission (without asking permission).
The new investigator award was my first contact with the world of grant-writing.
There is no library of grant examples, I ended up trying to write a grant having only seen one - a big mistake. Email the school's research leads (Tony+Karim) and faculty research office begging for examples.
OPDL occasionally has courses for grant-writing (search here for "grant" - ignore the "shut up and write" sessions), but not frequent (and clashes with teaching).
Library has no few on grant writing. I bought this (old) one - not EPSRC specific - post-covid financial panic, I'm sure the school will buy these for you
FEPs grant application team will be able to populate your JeS proposals with funding requestions. You can add the team member in charge of your application to your application to let them enter the (arcane) financial stuff, but they will also make small changes (re-submit etc...) without asking permission:
you can check likely panel dates on the epsrc website.
you will have to write a PI response before the final panel. The date for this is unknown, but you can suggest "unavailability" in je-s. For epsrc, the email comes from grants@je-s.ukri.org , and gives you a week to write a response (get help from someone who's done it before)

epsrc acceptance emails come form grants@rcuk.ac.uk , at which post the faculty office walks you through accepting it.

after you accept, the summary (and maybe other bits too?) become visible on the web.

Recording publications

Symplectic is where you deposit papers you've written. You should deposit them within a few months to make sure they're REF eligible and keep grant-providers happy. They are then automatically hosted by...
Our research group then pulls these to their page with a wordpress plugin. IT's (even slower) version of this.
Whiterose. A paper repository hosted by three universities. Interfaces via Symplectic. If things go wrong, email library deposit service
Research Data Repository. Hosing for bigger research outputs. example. Gives you a DOI. Upload instructions.
IRIS allows you to annotate research outputs for REF.
KRISTAL: Used by the faculty to track grant applications. I've never been given a login.
My Grants. A list of grants that the faculty is tracking. Docs. Intro video.

REF. Research excellence framework / five yearly excercise from UK govenment. Wikipeida has the best overview :/. No real motivation to engage with this (all star-ratings are anonymous). Determines the baseline research funding from central government (4 star paper is worth about £100k to school. Staff just have to write mysterious "100 words" for their publications (Tony's video).
IRIS allows you to annotate research outputs for REF:

This is populated autoamtically from Symplectic
You can nominate your 4 papers for REF on the "Outputs Review ->Nominate Output column -> check box next to the ones you want to nominate"
Through some undisclosed procedure, the nominated outputs are assessed externally. This can be found by clicking "Outputs Review (purple), -> scrolling down -> and clicking the tiny '+' to show the review and assessed REF classification (green)" (Click image to embiggen):
