The short version
- At an 8.2% average margin, a 20% discount usually turns a profitable appointment into a loss.
- Marketplace first visit commissions work the same way: Treatwell’s 35% is 42% of the booking once VAT is added.
- Roughly two thirds of first time clients never return, so discounts mostly buy expensive one offs.
- The fix for an empty column is structure: deposits, a last minute list, rebooking and packages. Not price cuts.
A full column on a Tuesday feels like winning.
If it is full of half price strangers, it is a loss you have chosen. It just does not feel like one, because the chairs are busy and the card machine is beeping.
The maths nobody does at the till
The average UK salon runs at about an 8.2% profit margin. On a £50 treatment, that is roughly £4 of actual profit after staff, stock, rent and everything else.
Now apply a 20% discount. The £10 you gave away did not come off your costs. It came off your revenue, and your costs stayed exactly where they were. The appointment now loses around £6.
You were not busy. You were paying people £6 each to sit in your chair.
The figures behind these numbers are on our salon marketing costs research page.
The platform version of the same trap
Deal sites and marketplace boosts are discounting with better branding.
Treatwell charges 35% commission on a new client’s first booking, which is 42% of the booking once VAT is added. Since April 2025 that commission applies even if the salon cancels the appointment. Booksy’s optional Boost takes 30% plus VAT for a new client. Fresha takes 20% with a minimum of around £6.
None of that is a scandal in itself. It is an introduction fee, and an introduction fee can be worth paying once, for a client who then comes back to you directly for years.
The trap is in the next number.
Two thirds of them never come back
Average first visit retention in salons is about 35%. Two out of three first timers are one offs.
For discount led first timers it is worse, because of who discounts attract. Deal followers are loyal to the deal, not the salon. They booked you because you were cheapest this month, and they will book the next salon that is cheapest next month.
So the typical discount transaction looks like this: you gave up most or all of your margin to acquire a client who was selected, by the mechanism itself, to be the least likely to return. Acquiring a new client already costs 5 to 25 times more than retaining one. Discounting manages to make the expensive route worse.
What discounting does to the clients you already have
There is a quieter cost. Your regulars see the offers too.
Run enough promotions and you train full price clients to wait for the next one. You also tell them, in public, what you really think your work is worth. Price is positioning. A salon that is always on offer is announcing that its rate card is fiction.
What to do with an empty column instead
Stop the leaks before buying water
No shows cost the average salon about 7% of monthly revenue, and deposits cut no show rates by 65%. If Tuesdays are patchy, deposits and reminders are the first fix, because they protect the bookings you already had. Our no shows and rebooking guide covers the setup.
Run a last minute list, not a sale
A simple text list of clients who want earlier appointments fills gaps at full price. “A 2pm has just opened up this Tuesday, want it?” converts because it is scarcity, and it goes to people who already know your prices.
Rebook at the basin
The cheapest Tuesday appointment to fill is the one that was booked six weeks ago by the client currently in your chair. Rebooking before they leave is the habit that empties the problem at its source.
Sell commitment, not cuts
A block of six for the price of five, or a monthly membership, looks superficially like a discount. It is the opposite. A discount gives margin to a stranger for one visit. A package trades a little margin for guaranteed repeat visits and cash up front. One compounds, the other does not. Where packages fit in the bigger picture is in our Start, Build, Scale guide for salons.
When a discount is actually fine
Three cases, used deliberately:
- A genuine opening offer for a new salon or a new therapist’s column, with the rebooking ask built into the visit.
- A models needed rate for training new treatments, clearly framed as training.
- Quiet hours pricing that is permanent and honest, a Tuesday morning rate, rather than a panic sale.
The common thread: each one has a purpose beyond filling today, and each one comes with a mechanism to turn the visit into a second visit. A discount without a rebooking plan is just margin leaving the building.
The sharp takeaway
Discounts are a bribe to strangers. Rebooking is an agreement with clients. Only one of them compounds.
