Gift cards and vouchers are everywhere in the UK — as birthday presents, workplace rewards and promotional offers. Most people treat them as a simple convenience, but they are a more interesting financial product than they look. Bought at the right time, from the right place, they can shave a few per cent off your everyday spending. Left in a drawer, they quietly expire. Given to employees, they carry tax consequences. This guide covers the practical side of gift cards: the different types, where to buy them cheaply, how to sell ones you do not want, how to protect your balance, and what HMRC thinks when an employer is involved.
What gift cards are and where they come from
A gift card is simply a pre-loaded card or voucher holding a specific cash value that can be spent at one retailer or a group of retailers. They come in two main forms. Physical cards are plastic, bought in-store or ordered online, and work at the till much like a debit card. E-vouchers are digital codes delivered by email or loaded into an app, which you show at checkout or enter online. Both do the same job; the e-voucher is simply faster to obtain and harder to lose.
Most British retailers sell gift cards, from supermarkets and department stores to restaurants and online shops. Some are retailer-specific — a Next card will only work at Next — while others, like One4all or Amazon gift cards, cover a group of retailers. Where you buy matters if you want perks: supermarkets such as Tesco, Sainsbury’s, Asda and Morrisons all stock cards for dozens of brands and often give you Clubcard or Nectar points on the price you pay. Online, platforms like Gift Cards Direct, Tesco Gift Cards and Amazon sell e-gift cards for immediate delivery, and WH Smith, the Post Office and newsagents carry popular cards for big high street names.
Before buying or using one, it is worth remembering that a gift card is not cash. Many expire after 12 to 24 months, though some retailers have no expiry at all — the terms vary, so check. They generally work only at one retailer or a small group, so do not assume portability. If you spend less than the value, you will not get the difference back in cash; the remainder stays on the card. They are usually non-refundable once bought. And some work only in physical stores while others are online-only, so check before you turn up at the till.
Buying gift cards at a discount
Here is where gift cards become a genuine money-saving tool. Through secondary market platforms, you can buy gift cards for less than their face value. The mechanics are simple: people and businesses sell unwanted cards at a discount, you pay, say, £85 for a card worth £100, and when you spend it you have saved £15. The size of the discount varies with the retailer, current demand, and how close the card is to its expiry date.
The three platforms worth knowing about in the UK are JamDoughnut, Cardyard and Zeek. JamDoughnut is an app selling discounted cards for hundreds of brands, with typical discounts from 2% to 15%; you buy through the app and use the e-voucher in-store or online, and the popular categories are supermarkets, restaurants, fashion and electronics. Cardyard is a website where individuals sell their unwanted cards; you buy at a discount and Cardyard holds the payment in escrow until you confirm the card works, with discounts typically running from 3% to 12% off face value. Zeek works in a similar way as an app and website, with discounts on UK retailer e-vouchers that move with supply and demand. Used regularly, the savings accumulate. If you spend £500 a month on groceries and buy Tesco gift cards at 4% off, that is £240 a year without changing anything about how you shop.
A concrete example makes the point:
| Detail | Amount |
|---|---|
| Face value | £200 |
| Price paid (JamDoughnut, 6% off) | £188 |
| Saving | £12 |
That £200 Argos card, bought at 6% off for a new TV, leaves £12 in your pocket. Small on its own; significant when it becomes a habit.
Selling unwanted gift cards
If you receive a card you will never use, you can turn it into cash rather than letting it expire. On Cardyard you list the card and set your asking price — usually 80% to 95% of face value — and once a buyer purchases it, Cardyard verifies the card and transfers the money to your bank account. Zeek runs a similar process, paying out cash minus a small commission. Alternatively, you can sell directly to individuals through Preloved or Facebook Marketplace, but that route carries more risk: meet in a public place and verify the balance before handing the card over.
A few habits improve the price you get. Sell promptly, because a card close to its expiry date is worth less. Check the balance before listing so you are selling the full value. Price competitively — if similar cards are listed at 10% off, you will need to match or beat that to shift yours. And factor any commission or listing fee into your asking price, or the sale can leave you worse off than a card you simply used.
Looking after your cards
Fraudsters treat gift cards like cash, so they deserve cash-like security. Keep the receipt when you buy a physical card — if it is lost or stolen, some retailers will replace it if you can prove the purchase. Where a retailer lets you register the card online, do it: registration links the card to your name and makes replacement far easier if it goes missing (not all retailers offer this, but it is worth doing wherever available). Store the card somewhere safe, the same way you would a £50 note, rather than leaving it loose in a bag. Check the balance regularly through the retailer’s website or customer service; this both tells you what you have to spend and flags any unauthorised use early. And never send a photo of the card code to anyone — scammers use codes to drain balances in minutes.
Getting the most out of them
The finishing touches are mostly about timing. Set a phone reminder a month before the expiry date so the value does not vanish unused. Check the balance before you shop so you can plan around it. Combine cards with seasonal sales — Black Friday, Boxing Day and the January markdowns stretch a £100 card further. Stack the discount with cashback by routing the purchase through a cashback website, earning money on top of the discounted card. And if you know you will spend at a particular shop anyway, buying a discounted card for yourself is effectively free money. The one rule of thumb that most often gets ignored: do not overbuy. A discounted card for a shop you never visit is money wasted either way.
Tax: when gift cards meet HMRC
Gift cards take on a different character in the workplace. When an employer gives a gift card to an employee, HMRC treats it as a benefit in kind. The value is added to the employee’s taxable income, income tax and National Insurance are due on it, and the employer must report it through payroll or on a P11D form.
The misconception many employers carry is that gift cards fall under the trivial benefits exemption, which allows gifts of up to £50 per occasion without tax consequences. In practice, HMRC has clarified that most gift cards are treated as cash equivalents and therefore do not qualify. The exemption itself is strict: the gift must not be cash or a cash voucher, it must not be a reward for performance or part of the employment contract, and the £50 limit applies per occasion. When a card can be exchanged for cash — which many can, these days — it sits firmly on the taxable side of the line.
For purely personal use there is nothing to worry about. If you buy gift cards for yourself or as presents, you are spending your own after-tax money and no further tax arises. Gifts of gift cards between friends or family are likewise not taxable. The one hobby that does attract HMRC’s attention is buying discounted cards and selling them at face value as a business: that can be treated as trading income, and you would need to declare it on your tax return if it exceeds the trading allowance.
Bottom line
Gift cards reward the organised. Buy discounted cards for shops you already use, sell the ones you will never touch, protect the balance like cash, and keep an eye on expiry dates — and a card that began life as an afterthought becomes a small, reliable discount on the shopping you were going to do anyway. For employers, the lesson is simpler: before handing out gift cards as rewards, check the HMRC rules, because most of them are taxable benefits no matter how well-intentioned.
