Domestic Refrigeration Service Equipment?

I posted this in the ‘Classifieds’ section but I feel it won’t get the attention we need so I’m taking a bloomin’ liberty on here!

Is there anyone who can advise what equipment would be required to kit out a refrigeration systems engineer?
The chap who we had lined up to start has, it would appear, let us down so we have no one to help in this matter and we want to but the kit in asap to prove to prospective work providers we have the technology.

Sorry for the cheek (and the long post!).

“Yes it’s true!

For our sins we are about to embark on the journey of the Refrigeration Service Engineer (no don’t laugh!) so was wondering if any body had good working kit they no longer use or preferably have never used.

But we do need some urgently!

Please pm if you might be able to help.

Cheers All.”

Thank you .
