<p>Duty free at Heathrow is run by World Duty Free in every terminal, airside only, after security. The genuine savings are on alcohol and tobacco, where you can bring home up to 42 litres of beer, 18 litres of still wine, 4 litres of spirits and £390 worth of other goods without paying UK tax or duty, provided you fall within your personal allowance. Perfume, cosmetics and electronics are a different story: they usually still carry standard VAT, so "duty free" on those categories does not always beat the high street.</p>
<h2>What "duty free" actually means in 2026</h2>
<p>The phrase is a leftover from before Brexit, when it meant something different. Since 1 January 2021, two changes shape what you see at Heathrow today. Tax-free shopping for visitors flying to non-EU destinations was scrapped, so overseas visitors leaving the UK no longer get automatic VAT refunds on general goods bought airside. At the same time, duty-free alcohol and tobacco sales to passengers flying to the EU came back, because the UK is no longer bound by the EU's internal single-market rules that had abolished them in 1999. In practice, this means alcohol and tobacco are the categories where Heathrow's duty-free prices can beat the supermarket or off-licence, because you are not paying UK excise duty or VAT on them, as long as you stay within your personal allowance and are leaving the country.</p>
<h2>Your personal allowance for bringing goods into Great Britain</h2>
<p>These are the current allowances set by HMRC for anyone arriving in England, Wales or Scotland from outside the UK, whether the goods were bought duty free or on the high street abroad. They apply on your way home, not on your way out through Heathrow, but they are exactly the limits that make airport duty-free shopping worth planning around.</p>

<p>Going over an allowance is not a case of paying duty only on the excess. If you bring in 19 litres of wine, for example, HMRC requires tax and duty on the full 19 litres, not just the extra litre. The same applies across every category, so it rarely makes sense to buy right up to the edge of a limit if you might add to it elsewhere on the trip.</p>
<h2>What is genuinely worth buying at Heathrow</h2>
<p>Spirits and tobacco are where the maths tends to work in your favour, because UK excise duty and VAT on those categories is high, and airside duty-free prices strip both out for passengers leaving the country within their allowance. A bottle of whisky or a carton of cigarettes at World Duty Free can be meaningfully cheaper than the same product on a UK high street.</p>
<p>Fragrance, cosmetics and electronics are a weaker case. Because standard VAT still applies to non-excise goods sold to outbound passengers, "duty free" pricing on perfume or tech is often close to, or barely below, high street or online prices. It is worth comparing the exact product price on your phone before buying, rather than assuming the airport price is automatically the best deal.</p>
<p>Ordering ahead through World Duty Free's Reserve & Collect service, where you pick your items online and collect them airside, can sometimes secure a better price than walking in and buying on the day, so it is worth checking before you fly if you already know what you want.</p>
<h2>Where to find World Duty Free at Heathrow</h2>
<p>World Duty Free has a store in every terminal, positioned airside so you can only reach it after clearing security. If you are flying from Terminal 2, 3, 4 or 5, look for the main duty-free hall as you come through security into the departures shopping area; each terminal's interactive map on Heathrow's own website will point you to the exact unit if you are short on time.</p>
<h2>Buying on arrival versus buying before you fly</h2>
<p>World Duty Free also operates arrivals stores at some terminals, so you do not have to buy everything before you leave. This can be useful if you would rather not carry a bottle of spirits around your destination, though ranges and offers on arrival are usually smaller than the main departures store.</p>
<h2>Bringing goods back through UK customs</h2>
<p>The allowances above apply the moment you land back in Great Britain, regardless of where you bought the goods, whether that was duty free at your destination airport, on the plane, or on the high street abroad. If your total across a category is under the limit, you can walk through the green "nothing to declare" channel. If you are over on anything, you must declare it and pay the tax and duty due on the whole amount in that category, not just the surplus.</p>
<h2>Practical tips for Heathrow duty-free shopping</h2>
<ul>
<li>Check prices on your phone before buying if you are unsure whether a perfume or gadget is genuinely cheaper than at home.</li>
<li>Keep receipts until you are through customs on your return, in case you need to show what you paid.</li>
<li>If you are travelling as a family or group, remember personal allowances cannot be pooled or combined between passengers.</li>
<li>Liquids bought airside after security, including duty-free spirits, are sealed in tamper-evident bags and are fine to carry onto connecting flights when accompanied by the receipt, but rules can vary if you are transferring through a different airport, so check with your connecting carrier.</li>
