Cult Beauty has been around since 2008 and stocks well over 8,000 products, which is a lot for a beauty site that started out as a small curated edit. The range runs from Augustinus Bader and 111Skin at the top end through Drunk Elephant, Sunday Riley and Charlotte Tilbury, down to £10 lip balms and indie brands nobody else in the UK carries yet.
FIRST15 gives you 15% off, but it works once. It is a first order code, so the account you sign up with gets one shot and then never again. On a site where a basket can be £25 or £250, that single use is worth anywhere from £3.75 to £35 depending on what is in it.
Most people spend it on a small order just to test the site out. That is the expensive mistake.

FIRST15 Is Worth £3.75 Or £30, Your Choice
The minimum spend is £25. Fifteen percent of that is £3.75.
Now take one Augustinus Bader Rich Cream, which sits around the £200 mark. Same code, same 15%, roughly £30 off. The gap between a careless first order and a deliberate one is about £27 on this site. Not enough people think about that before typing the code in.
If there is a luxury skincare purchase you have been circling for months, this is the order to put it in.
Cult Beauty Says Up To 15%, With FIRST15
Read their banner properly and it says up to 15% off your first haul.
That phrasing is doing a job. Brand exclusions apply, and the site states outright that they can change which brands are excluded whenever they want. At beauty retailers the excluded list tends to be the premium end, which is exactly where you want to spend this code.
Test it before you commit. Put the expensive item in the basket on its own, apply FIRST15, and check the discount line actually moves. If nothing happens, that brand is out and the code belongs somewhere else.
The £25 Minimum Can Cost You Free Delivery
Free UK delivery starts at £25. The code minimum is also £25.
Land a basket at exactly £25 and the discount pulls you down to £21.25, which drops you under the free shipping line. Next day delivery runs £5.95, so a code that saved £3.75 can cost you more than it gave back.
Build past £30 and neither threshold is a problem.
Better Discounts Exist Once The Code Is Spent
FIRST15 dies with your first order, but Cult Beauty has other routes and most people never find them.
Cult Status is the loyalty programme and it earns points on everything you spend. Members get a birthday discount each year, usually between £10 and £25 depending on tier, which beats 15% on a small basket outright.
- Students get 20%, which is better than FIRST15 was in the first place.
- The app runs its own 15% offer on app orders, separate from the website code.
None of these stack. Cult Beauty’s terms say plainly that offers cannot be used in conjunction with any other promotion, so it is one discount per order, always.
Wait Until You Know What You Want
The code is active through September 2026 and there is no advantage to rushing it. Work out which luxury skincare product you actually want, check it is not on the excluded list, build the basket past £30, then spend your one shot.
