Take the flexible rate whenever it costs less than about a fifth more than the non-refundable one, or whenever any part of the trip is still uncertain. Take the non-refundable rate only when the saving is large, the dates cannot move and you have already checked what your insurance covers. Booking online gives you no cooling-off period on a hotel room, so the only cancellation right you have is the one written into the rate you chose.
Most London hotels sell the same room twice. One version is cheaper, charged to your card the moment you book and lost if you do not turn up. The other costs more, takes nothing or almost nothing up front, and can be cancelled free of charge until a stated deadline. Every booking site shows both, usually one line apart.
Which one is right depends on arithmetic and on how firm your plans are, not on temperament. This page does the arithmetic, explains what each rate actually does to your money, and sets out what happens when you have to cancel a room you paid for in advance. The related question of how early to commit is answered in our page on timing a London booking, and how to read a listing safely before you pay is in booking tips and accommodation scams.
Flexible or non-refundable: the short version
- Cooling-off period
- None. UK online-shopping cancellation rights do not apply to accommodation booked for set dates
- Flexible rate
- Free cancellation until a deadline; often nothing charged until arrival
- Non-refundable rate
- Usually charged in full at the moment of booking; no change, no refund
- Our rule of thumb
- Pay up to about 20% more for flexibility; above that, think harder
- The deadline
- A date and a time, in UK time (GMT in winter, BST in summer)
- If the hotel cancels
- That is a different matter entirely, and you are owed more than your money back
- Card protection
- Section 75 covers a purchase over £100 on a credit card. It does not cover changing your mind
There is no 14-day cooling-off period on a hotel room
Visitors from the European Union and from the UK alike often assume that anything bought online can be cancelled within fourteen days. For most goods and many services in Britain, that is true. For accommodation, it is not.
The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 set out the online cancellation right, and regulation 28 lists what falls outside it. One of the exclusions is "the supply of accommodation, transport of goods, vehicle rental services, catering or services related to leisure activities, if the contract provides for a specific date or period of performance". A hotel room for the nights of 4 to 7 June is exactly that.
The practical consequence is worth stating plainly. When you tick the box on a non-refundable rate, no statutory right sits behind you. What you can get back afterwards depends on the hotel's own terms, on goodwill, and in a narrow set of cases on whether the charge itself is a fair one. Everything else on this page follows from that.
What the two rates actually do to your money
The labels vary between sites, but the mechanics are consistent.
| Flexible / fully refundable | Non-refundable / advance purchase | |
|---|---|---|
| When you are charged | Usually on arrival or departure, though some rates take one night up front | In full, at the moment you book |
| Card details | Often held as a guarantee only, not charged | Taken as a payment |
| Changing dates | Cancel and rebook at the new price | Usually not permitted at all |
| Arriving a day late | Normally fine; the first night may still be charged | The whole stay is often forfeited as a no-show |
| If the price falls | Rebook cheaper and cancel the old room | Nothing to be done |
| Typical saving | — | Commonly quoted at around a tenth to a quarter less |
Two details catch people out. First, "free cancellation" and "no prepayment" are separate promises and a rate can carry one without the other, so a flexible booking may still take money at the moment you make it. Second, a card held only as a guarantee can still be charged if nobody arrives, which means a flexible room you simply forget to cancel is not a free one.
The arithmetic, with a worked example
Set the two totals side by side for the entire stay rather than for one night. The premium is what you are buying; the total is what you are risking.
Take an illustrative four-night stay. Suppose the non-refundable rate comes to £600 for the four nights and the flexible rate for the same room comes to £690. The premium is £90, or 15% of the cheaper total. You are effectively paying £90 to insure £600.
Now ask yourself one question: what are the chances, honestly, that this trip does not happen or these dates move? If you think there is better than a one-in-six chance, the flexible rate is already the cheaper choice on expectation. Most people planning a city break four months ahead, around work, school terms, flights and other people, are well above one in six.
Where the sum flips is when the premium is large. If the same comparison were £600 against £840, you would be paying 40% for flexibility, and at that level it is usually better to take the non-refundable rate for the nights you are certain about and hold a separate flexible room only for the nights you are not.
Split the booking rather than the difference. On a longer stay, a mixed approach often wins: non-refundable for the middle nights, which almost never change, and flexible for the first and last, which are the ones a delayed or rebooked flight actually moves. Two bookings at the same hotel are a small nuisance at the desk and can save a great deal.
Reading the deadline, which is where most money is lost
"Free cancellation" without a deadline attached is meaningless, and the deadline is the part people skim. Write it down as a date and a time.
- It has an hour. Deadlines are commonly expressed as 23:59 or 18:00 on a given day, or as a number of days before arrival. A booking cancelled an hour late is treated the same as one not cancelled at all.
- The hour is London's. Britain uses GMT in winter and British Summer Time, one hour ahead, from the last Sunday in March to the last Sunday in October. If you are booking from a different time zone, convert once and put the converted time in your calendar.
- The penalty is not always the whole stay. Many hotels charge one night for a late cancellation and release the rest. Some charge everything. The terms say which.
- A change of dates is a cancellation. On most flexible rates you cannot move a booking; you cancel it and make a new one at whatever the new dates now cost.
Set two reminders: one a week before the deadline, when you should compare prices again, and one the day before it, when you should decide. That single habit is the whole benefit of a flexible rate, and it is worthless if the deadline passes unnoticed.
Booking direct or through a booking site changes how you cancel
If you book through an online travel agent, your contract is with that agent, not with the hotel. The hotel's reception desk often cannot cancel or amend the booking even when it wants to, and will tell you to go back to the site. That adds a step and, on a tight deadline, sometimes an hour on hold.
Booking direct usually makes changes easier, because whoever answers can see the reservation and alter it. Requests such as a later arrival or a quieter room are simpler to arrange that way too. Price is not a reliable tiebreaker either way, so put the two final totals and the two sets of cancellation terms next to each other, then keep a screenshot or a PDF of the one you choose, terms included.
Watch for one asymmetry. The same room on the same night can carry a different cancellation deadline on the hotel's own site and on an agent's, and the label "free cancellation" may hide a fee charged by the agent rather than the hotel. The Competition and Markets Authority's price transparency guidance requires mandatory charges to be shown in the total from the start; read the total and the terms together rather than the headline.
What actually happens if you have to cancel a non-refundable room
The rate says no refund, and in most cases that is the end of it. There are still four things worth doing, in this order.
- Tell the hotel as early as you can, by email, and ask. A hotel that can re-sell the room has every reason to be reasonable, and a polite message eight weeks ahead is answered very differently from a phone call on the day. Ask about a credit for a future stay if a refund is refused. Our guide to complaining effectively in Britain explains the tone that works here.
- Check your insurance before you assume you have lost the money. Cancellation cover is part of most travel policies, and the reasons it accepts are set out in the wording rather than decided case by case. What to look for is in our page on insuring a trip to Britain.
- Know what card protection does and does not do. Under section 75 of the Consumer Credit Act 1974, a credit provider shares liability with the business for a breach of contract or a misrepresentation, on a cash price above £100 and up to £30,000. The Financial Ombudsman Service is clear that this covers credit rather than debit cards, and that it is a remedy for something the business got wrong. A change in your own plans is not that.
- Understand the limits of a chargeback. A chargeback is a card-scheme process rather than a legal right, available on debit and credit cards, with the Financial Ombudsman noting a window of around 120 days and no obligation on the bank to raise one. It is for services not provided, not for a booking you no longer want.
There is one narrower point worth knowing. Under the Consumer Rights Act 2015, a contract term is unfair, and not binding on the consumer, if contrary to the requirement of good faith it causes a significant imbalance in the parties' rights to the detriment of the consumer. Whether a particular cancellation charge crosses that line is a question for a court or an ombudsman rather than for a travel guide, and we cannot tell you how it would be decided. If a charge looks disproportionate to you, take proper advice rather than guidance from a website.
When the hotel cancels on you
This is the reverse case, and it is not rare in a city that sells out twenty-odd weekends a year. Hotels overbook, building work overruns, and rooms are occasionally taken out of service at short notice. The trade's word for moving a confirmed guest to another hotel is "walking" them.
If it happens, do not accept a bare refund on the doorstep. Ask the hotel, there and then, to find and pay for an equivalent room for the same nights, to cover the taxi to it, and to refund any difference in price. Ask for it in writing, keep the original confirmation, and if the substitute hotel is a long way out, say so before you get in the cab. Deal with it that evening: the leverage disappears once you have slept somewhere.
A hotel that cannot house you has not simply "cancelled". It has failed to provide something you had booked and, on a non-refundable rate, already paid for. This is the case in which a credit card payment above £100 and a dated written record of the promise both earn their keep, and it is the best reason to put the deposit on a credit card rather than a debit one.
The London dates when only a flexible rate makes sense
Some weekends in London do not simply become expensive, they run out of rooms, and on those dates a non-refundable booking is a bet on your own travel arrangements rather than on the hotel. The shape to remember is the marathon in late April, the flower show in the third week of May, the Wimbledon fortnight, carnival on the last weekend of August, and 31 December.
Three other situations argue for flexibility whatever the dates.
- Your entry to the UK is not yet settled. If you still need an electronic travel authorisation or a visa, do not prepay a room: see UK entry requirements.
- Your travel depends on one train, one flight or one ferry. Industrial action is announced with little notice, and our pages on Tube strikes and visiting during a strike explain how much moves when it happens.
- You are travelling with children, or as a party of four. Anything sleeping more than two people is in short supply here, and holding one while you compare costs nothing on a flexible rate: see family rooms and rooms for three.
Two final housekeeping points. A flexible rate is not a licence to hold four rooms at once; hotels notice, and a pattern of ghost bookings can end with a card declined. And a cheaper rate is only cheaper when the rest of the bill matches, so read what each one includes before you compare. Breakfast, parking and the other add-ons are in our page on the extras, and the standard London hotel room describes what the money actually buys. However you pay, card payments in Britain explains holds, pre-authorisations and surcharges, while the cost of a London trip shows where the room sits among everything else.
Frequently asked questions
Can I cancel a London hotel booking within 14 days under UK law?
No. The Consumer Contracts Regulations 2013 exclude accommodation booked for a specific date or period from the online cancellation right, so there is no statutory cooling-off period on a hotel room. Your only right to cancel is the one written into the rate you booked.
Is the flexible rate worth the extra cost in London?
Usually, if the premium is under about a fifth of the total and your dates are more than a few weeks away. You are paying a small sum to protect a much larger one, and London prices move enough that re-checking before the deadline often recovers the premium anyway.
What does non-refundable actually mean at a London hotel?
In most cases the full amount is charged to your card at the moment you book, the dates cannot be changed, and nothing is returned if you do not come. Some hotels will offer a credit for a future stay as a goodwill gesture, but they are not obliged to, so ask early rather than on the day.
Will my credit card refund a hotel room I cancelled?
Not if you simply changed your mind. Section 75 of the Consumer Credit Act 1974 gives a shared liability with the business for a breach of contract or a misrepresentation, on credit purchases above £100 and up to £30,000. Chargeback is a separate card-scheme process, normally raised within about 120 days, and it too is aimed at a service that was not delivered.
What should I do if the hotel cancels my booking?
Ask the hotel to arrange and pay for equivalent accommodation for the same nights, plus the transfer to it, and to refund any difference in price. Get the offer in writing before you leave the desk and keep your original confirmation. Settle it that evening rather than afterwards.
Does travel insurance cover a non-refundable hotel in London?
Many policies include cancellation cover, but only for the reasons listed in the policy wording, and usually only if the policy was bought before the reason arose. Read the cancellation section before you book a prepaid room, not after, and check the excess as well as the limit.
