A ticket advertised at £45 looks like a bargain until checkout adds a £4 booking fee and a £2 processing charge. Suddenly it costs £51, and neither extra payment can be removed. This is drip pricing: attracting customers with one figure, then revealing unavoidable costs as they move towards payment.
For anyone researching drip pricing and consumer rights in the UK, the central question is whether a customer can actually buy the product at its advertised price. If not, the pricing may breach consumer law.
Why a late fee matters
Hidden charges distort comparisons. A £45 ticket with £6 in compulsory extras is not cheaper than a genuinely all-inclusive £48 ticket. Yet the lower figure may win attention before someone has spent time selecting seats or entering details. The same problem can arise with hotels, delivery orders, online services and gym memberships.
The issue is not always the existence of a charge. It is concealing an unavoidable part of the cost until the buyer is invested in the purchase.
What UK drip pricing law requires
Under the Digital Markets, Competition and Consumers Act 2024, unfair commercial practices rules have applied since April 2025. The Competition and Markets Authority (CMA) says traders generally must present the total price upfront, including mandatory fees, taxes and charges. Its price-transparency guidance was updated in January 2026.
The duty can arise before checkout. A product listing, social media advert or promotional email showing a product and its price will normally be an invitation to purchase. Customers should receive clear and prominent price information then, rather than discovering the true total on the final payment screen.
Hiding an unavoidable surcharge in small print while advertising a lower headline figure will not normally satisfy the rules. An advertised price needs to be one that a customer can realistically pay.
Mandatory fees versus optional extras
An unavoidable booking fee, service charge or tax ordinarily belongs in the displayed total. If everyone must pay a £3 transaction charge on a £20 ticket, the relevant starting price is generally £23, not £20.
A genuinely optional extra is different. Buyers might choose gift wrapping, cancellation insurance or faster delivery. The trader can show those charges separately because the product remains available without them. However, the seller must explain the cost clearly and obtain express consent before charging. Pre-ticked boxes and automatically added paid extras do not count as an active choice.
What if the full price is not yet known?
Sometimes a charge depends on the customer’s postcode, measurements or requirements. The business must prominently explain how the cost will be calculated and show the full total as soon as it can reasonably determine it.
Where delivery is compulsory but customers can choose different delivery services, CMA guidance says the cheapest required option should be reflected in the total until another is selected. Variable delivery is not a licence to reveal all costs at the last moment.
A practical test: compare two ticket websites
Imagine Website A advertises a theatre ticket at £51, including all compulsory fees. Website B advertises the same ticket at £45, then adds £4 for booking and £2 for processing after seat selection. Both eventually charge £51, but Website B’s headline price gives a misleading impression of value.
Change one detail: Website B sells the ticket for £45 and offers clearly priced, optional £6 cancellation protection that starts unselected. Now the buyer can genuinely complete the purchase for £45. That distinction matters more than the name of the fee.
When considering hidden fees in the UK, ask three questions: Is the fee unavoidable? Could the total have been shown earlier? Did you actively choose any extra being charged?
Hotels, subscriptions and ‘from’ prices
Hotel resort fees and mandatory local charges should normally be included in the overall price where they can reasonably be calculated, even when some money is paid at the property. A split between ‘pay now’ and ‘pay later’ should not obscure the full cost.
Rolling monthly subscriptions should show the complete price payable for the month, including compulsory charges. For contracts with a minimum term, traders may show the cumulative contract price or the periodic payment alongside the number of payments. Joining fees cannot simply disappear behind a low monthly headline.
A ‘from’ price can be legitimate, but it must include applicable unavoidable charges and accurately describe what the starting figure buys. Dynamic pricing, where a base price changes with demand, is a separate issue and does not excuse hidden mandatory fees.
What to do when the price jumps at checkout
Before paying, check whether the added fee is compulsory or a service you can decline. Compare the initial listing with the order summary, and save screenshots showing the headline price, each fee, the final total and the date. This evidence is useful when a trader changes its website.
If you have paid, complain to the retailer in writing. Identify the advertised amount, describe the charge, explain why it was unavoidable or added without your consent, and request an appropriate refund or remedy. Keep the receipt, order confirmation and replies.
There is a legal distinction between two situations. A customer charged for an optional extra without express consent has a right to reclaim that payment. Misleading presentation of a mandatory fee can trigger enforcement and potentially other remedies, but it does not mean that every customer automatically receives that fee back. The circumstances and contractual position matter.
If the retailer refuses to help, seek consumer advice. Citizens Advice can guide consumers in England and Wales and refer suspected unfair trading to Trading Standards; Scotland and Northern Ireland have their own relevant advice arrangements. Card payments may also offer chargeback or Section 75 remedies where eligibility conditions apply.
The CMA and Trading Standards can investigate broader unfair-pricing practices, although reporting a business does not itself resolve an individual refund claim. Related guidance on online shopping rights, unfair contract terms and how to make a consumer complaint may help you decide what to do next.
Frequently asked questions
Is drip pricing illegal in the UK?
Concealing compulsory fees until later in the purchase journey is prohibited under the unfair commercial practices rules. Transparent, genuinely optional extras are different.
Can a company add a booking fee at checkout?
A mandatory booking fee should generally be included in the total shown upfront, including in an advertised ‘from’ price. It should not appear as an unavoidable surprise at the end.
Can I demand a refund of a hidden fee?
You can challenge it and seek a remedy. A paid optional extra added without express consent is refundable; remedies for misleading mandatory charges depend on the facts.
Who handles complaints about hidden charges?
Start with the seller. Consumer advice services and Trading Standards can assist with reporting concerns, while regulators consider enforcement. A card provider may help with an eligible payment dispute.
The price you compare should be the price you can pay
Price transparency and consumer rights are meaningful only when buyers can compare realistic totals. If a compulsory fee appears late, document the difference and challenge the trader. The test remains simple: could an ordinary customer complete the advertised purchase for the price that first caught their eye?
