About Function18
Function18 is a UK golf specialist selling men's golf clothing, shoes and accessories from Hugo Boss, Galvin Green, FootJoy, Ralph Lauren, Nike, adidas and Puma.
Every UK order already ships free by Royal Mail Tracked 24, so a Function18 discount code mainly has to beat the sale prices, which reach up to 50% off selected styles.
Function18 describes itself as a specialist golf apparel store whose buyers have more than 20 years of experience sourcing designer golf clothing for golfers across the UK. It mixes golf labels with high street fashion names, carries some designs it says are sold only through Function18.com, and states that everything listed on the site is in stock and ready to dispatch.
The range goes well beyond shirts and trousers, taking in mid layers, gilets, waterproofs, base layers and outerwear, along with spiked and spikeless golf shoes and sliders. On the equipment side it stocks golf bags, balls, trolleys, towels, umbrellas and luggage. UK customers can join F18 Rewards to collect points on purchases and redeem them later, and they can swap a size through an instant exchange.

How to use a Function18 discount code
- Function18 takes payment in GBP only, so any discount code comes off a pound total that already includes VAT.
- Before using one, compare its saving with the marked-down price on sale styles, which run up to 50% off.
- If you're collecting Function18 Rewards points, keep in mind that a refunded return takes those points back off your balance.
- Returns over £250, golf bags and trolleys need a message to Function18 before you send them, which matters if a code tempts you into a large basket you might trim later.
- Orders before 16.00 UK time on a working day ship the same day.
More ways to save at Function18
- Function18 Rewards gives UK customers points on every purchase, which you redeem later for discounts.
- The End of Season Sale had selected styles at up to 50% off at the end of October, and Function18 also runs a Summer Sale, announced in a July 2026 poSt. Gift vouchers are on sale for golfers who'd rather choose their own kit.
- Klarna sits among the payment options if you'd rather spread the cost of a new waterproof or pair of shoes.
