The short answer
Put them on the site. Placement fees and any ongoing fees, stated, with what is included and what triggers the charge. Families compare agencies on fees, and the one that hides them is compared on the assumption they are high.
You do not have to publish every variation. You do have to let a family work out roughly what you cost before they ring.
What "stated" means in practice
Four things, per service:
The basis. A percentage of first-year gross salary, a flat placement fee, or a registration fee plus a placement fee. Temporary and emergency cover is usually charged differently, often as a margin on the nanny's daily or hourly rate.
The trigger. Nothing to register or to interview; the fee falls due when the family makes an offer and the candidate accepts. If a retainer applies to a search, say the amount and whether it comes off the placement fee.
The tax position. Whether the figure includes VAT or sales tax. UK and EU consumer prices are normally shown inclusive.
The guarantee. How long the replacement period runs, what counts as a qualifying departure, and whether you replace or refund.
Gross or net, said out loud
Nanny pay is still quoted net in several markets, and a percentage calculated on the wrong basis is a large number. Write which one you use.
Add a line acknowledging that the family, as the employer in most nanny placements, also carries payroll, employer contributions and insurance, and point them at a payroll provider. That paragraph loses you nobody and gains you the families who were going to discover it later and feel misled.
Candidates pay nothing, and say so
For most nanny agencies the answer is that a candidate pays no fee for being found work. In the UK, the conduct regulations governing employment agencies restrict charging work-seekers for that, and other jurisdictions take similar lines. Whatever applies where you operate, put one clear sentence on the candidate route.
It costs you nothing, it removes the suspicion that you are an upfront-fee operator, and it improves the quality of the people who register. Confirm the exact position locally rather than borrowing wording from another country.
Au pair placements get their own line
Au pair arrangements are not nanny salaries. Pocket money or a stipend, board and lodging, a language or study element, and hours limits set by the host country's scheme. Price them separately, explain what the family pays you and what they pay the au pair, and say which countries you place into and out of.
Merging the two into one number confuses the only two audiences you have.
What the fee buys
Under the numbers, six or seven lines listing the work: shortlisting, vetting and checks, reference taking, interview coordination, contract and job description templates, salary guidance and support through the first weeks.
Then link the vetting page. Almost every fee objection is a vetting question wearing a different hat, and the page that answers it is one click away.
Where the fees page sits
On the family route, in the main navigation, not inside a downloadable PDF and not behind a form. A fee schedule you have to request is a fee schedule the family assumes they cannot afford.
Put the enquiry form or a consultation booking directly under the table. A family that has just accepted your fee is at the point of acting.
Keep it true
Build the table as records, one row per service, so a change is a five minute edit. Then check that the site, your terms of business and your invoice template agree on the basis, the trigger and the guarantee. They often do not, and the gap surfaces at the worst possible moment.
Diary a review twice a year, and edit the page the day you change what you charge rather than the month after.
Where this sits
A stated fee table, a clear trigger, a real guarantee period and a plain line on what candidates pay are part of every nanny agency website we build, and the same pricing pattern runs through our childcare websites. Our own packages are on pricing. Publish the fee and the conversation moves to the work.
