Service charge is the only part of the payroll that staff discuss among themselves in detail. Get the structure wrong and you will hear about it — usually from the kitchen, usually at the worst time.
Most independent venues distribute tips in a way that was decided years ago by somebody who has since left. It works until it doesn't: a new chef arrives, compares their share with a runner's, and a conversation starts that the business has no good answer to.
This is worth getting right on two separate grounds, and it helps to keep them apart in your head. There is the compliance question, which is about structure and records. And there is the fairness question, which is about your team actually believing the split is reasonable. A scheme can satisfy one and fail badly at the other.
A tronc is a separate arrangement for distributing tips and service charge, run by a troncmaster who decides the allocation independently of the employer. That independence is the whole point — it is what distinguishes distributed tips from ordinary wages, and it changes how the payments are treated for National Insurance.
Two things follow from that, and both get missed:
Separately from the tronc structure, UK rules require qualifying tips to be passed to workers without deduction, distributed fairly, with a written policy and records kept. Workers can request their own records.
"Fairly" does not mean equally. It means you need a defensible basis — one you could explain to an employment tribunal, but more importantly one you can explain to a commis chef on a Tuesday without it sounding arbitrary.
The test that matters day to day is not whether the split is legal. It is whether you can explain it out loud to the person who thinks they are getting less than they should.
This is where most schemes actually fail, and it is rarely a legal problem. It is a retention problem.
If front of house is taking £7 an hour in tronc and the kitchen is on £2.50, you will lose chefs — not immediately, and not with an explanation, but you will lose them. In a market where good kitchen staff are the hardest thing to replace, a distribution gap that big is an expensive way to save money.
There is no correct ratio. What matters is that the split was decided rather than inherited, that somebody can articulate the reasoning, and that it gets revisited when the business changes.
A practical test: if you cannot explain your current split without starting the sentence "it's just always been…", it is due a review. That phrase is the tell.
That last point catches people out more than you would expect. If the menu says "discretionary" and the till treats it as mandatory, the two are telling different stories — and that has VAT implications as well as tips ones.
None of this is difficult. It is simply the kind of administration that never becomes urgent until someone complains, at which point it is both urgent and awkward.
