How to Start an Online Travel Agency in the UK
By Travel White Label · Published 13 October 2026 · Updated 13 October 2026
To start an online travel agency in the UK, you set up a company, decide what you will sell, put the right financial protection in place (ATOL for flights and flight packages, plus package travel rules), sign up with travel suppliers, then launch a booking website with a payment gateway.
None of these steps needs a big upfront budget if you choose the right partners, but the order matters. This guide walks a UK founder through each step, with official sources linked so you can check the rules for yourself.
This guide is general information, not legal or financial advice. Speak to an accountant and, for licensing, the Civil Aviation Authority (CAA) or a travel law adviser before you trade.

A launch checklist, key takeaways and FAQs
What does an online travel agency actually do?
An online travel agency (OTA) sells flights, hotels, packages and extras to customers through a website rather than (or as well as) a high street shop. Behind the search box, the agency pulls live prices and availability from suppliers, adds its own markup, takes payment and issues confirmations.
Before you register anything, be clear which of these roles you will play, because it changes your licensing and your contracts:
Agent: you sell another company's travel products on their behalf. The supplier or tour operator is the "principal" and carries most of the responsibility for delivering the trip.
Principal or tour operator: you put travel components together and sell them under your own name. You take on more legal responsibility, including for packages under the Package Travel Regulations.
B2C: you sell direct to the public through your own branded site.
B2B: you sell to other agents (sub-agents) through a trade portal with logins, credit limits and agent markups.
Many UK agencies start as B2C agents in a niche they already know, then add packages or a B2B channel once bookings are flowing.
Step 1: Choose your niche and business model
"Cheap flights to everywhere" is a crowded market. A clear niche makes your marketing cheaper, your supplier choice simpler and your website easier to build. Good niches usually come from something you already understand well.
Destination: for example, flights and hotels to a region where you have family, language or supplier connections.
Customer group: for example, Umrah pilgrims, students, corporate travellers or large family groups.
Trip type: for example, city breaks, honeymoons, ski trips or long-haul tailor-made holidays.
Channel: B2C to the public, B2B to other agents, or both.
Write down three things before moving on: who your customer is, what they buy (flight only, hotel only, packages) and how you earn (markup, commission or service fees). Those answers drive every later step.
Step 2: Set up your company
Most founders trade as a private limited company, although some start as sole traders. A limited company keeps business and personal finances separate, and suppliers and payment providers often expect one.
Register the business: set up a limited company with Companies House, or register as a sole trader with HMRC.
Open a business bank account: keep customer money and business costs apart from day one. It makes supplier payments, reconciliation and any protection arrangements far easier.
Check VAT with your accountant: see when you must register for VAT, and ask whether the Tour Operators' Margin Scheme (TOMS) applies to what you sell. Travel VAT rules are specialist, so get advice early.
Pay the data protection fee: you will hold passport details, contact data and payment records, so check whether you need to pay the ICO data protection fee and write a clear privacy policy.
Arrange insurance: ask a broker about professional indemnity and public liability cover for a travel business.
Keep your company name, trading name, address and phone number identical everywhere: Companies House, your website, Google Business Profile and supplier forms.
Step 3: Understand ATOL, ABTA and package travel rules
This is the step new agencies most often get wrong. UK customers expect their money to be protected if a travel company fails, and the law requires protection in many cases.
ATOL: the Air Travel Organiser's Licence is run by the CAA. If you sell flights or packages that include a flight to UK customers, ATOL rules are likely to apply. Depending on how you sell, you either hold your own ATOL or sell as an agent for an ATOL holder under the CAA's rules. Read the CAA's ATOL protection pages before you sell any flights.
Package Travel Regulations: the Package Travel and Linked Travel Arrangements Regulations 2018 set out when you are selling a "package" or "linked travel arrangement", and the insolvency protection and information you must provide.
ABTA: ABTA is a trade association, not a government licence. Membership is voluntary, but many customers look for the logo, and membership comes with a code of conduct and financial protection arrangements for some non-flight bookings. Check ABTA's website for current requirements.
If you sell on a white label platform, check exactly whose protection applies to each booking. On TravelWhiteLabel, our suppliers are ATOL and ABTA protected. TravelWhiteLabel does not hold an ATOL, and using our platform does not give your agency its own licence. If you plan to put your own packages together, speak to the CAA or a travel law adviser about whether you need your own ATOL.
Step 4: Choose your travel suppliers
Your website is only as good as the prices and availability behind it. There are three common routes to travel content:
GDS (Global Distribution System): Amadeus, Sabre and Travelport give access to airline fares. A direct GDS contract usually involves its own agreement, fees and certification work.
Hotel bedbanks and APIs: wholesalers such as HotelBeds, Ratehawk, TBO, Stuba and DOTW supply hotel rooms at net rates you mark up.
Consolidators and platform suppliers: instead of signing every contract yourself, you book through a partner who already holds the supplier connections.
For a new agency, the third route is usually the fastest way to start selling. On TravelWhiteLabel, our suppliers are included at no extra cost on every plan. If you already have your own GDS or bedbank contract, you can connect it instead; any charges from those providers are billed by them, not by us. Our travel API integration page explains the options.
Step 5: Launch your booking website
You have two broad choices: build your own booking website or use a white label platform branded as your own. We compare both cost lines in detail in how much a travel booking website costs in the UK.
Whichever you choose, a UK customer-facing travel site needs these basics:
Search and booking: flight, hotel and package search with clear filters, fares rules and a simple checkout.
Your branding and domain: your logo, colours and your own domain name, so customers trust you rather than a third party.
Mobile-first layout: many customers search and book on their phones.
Trust content: company details, protection information, terms, privacy and cookie policies, and real contact details.
Back office: bookings, customers, markups, staff logins and reports.
Our B2C travel booking platform covers these out of the box, and there is no setup fee. If you are new to the white label model, our white label travel website UK guide explains what you get and how launch works.
Start on a free beta site first
The safest way to launch is to test before you pay. TravelWhiteLabel gives you a free beta site, so you can check searches, branding and the booking flow, and billing only starts when you go live. After that, plans are Growth at £179 per month, Scale at £599 per month and Elite at £999 per month, with API access at £999 per month. Pay 12 months upfront and you get 2 months free. See the full comparison on our pricing section.
Step 6: Set up payments
Customers pay you online, so you need a payment gateway and, usually, a merchant account. Common choices for UK agencies include Stripe, PayPal and Worldpay.
Apply early: some payment providers treat travel as higher risk because customers pay before they travel. Expect questions about your business model, protection and refund process.
Know your fees: gateway and card fees are charged by your payment provider. They are not part of a TravelWhiteLabel plan.
Keep card data off your servers: use a hosted or embedded checkout from your gateway so you stay within the PCI DSS card security standard as simply as possible.
Plan deposits and refunds: decide when you take deposits, when balances are due and how you handle cancellations, and put it in your booking terms.
Step 7: Market your agency and win your first bookings
A new booking site will not get traffic on its own. Pick two or three channels and do them well rather than trying everything at once.
Google Business Profile: free, and it helps local customers find you. Use the same name, address and phone number as your website.
SEO content: destination guides and helpful pages for your niche bring in searchers over time.
Paid search and meta search: Google Ads and meta search sites such as Skyscanner, Kayak and Jetcost can send ready-to-book visitors, but set budgets carefully.
Community and referrals: mosques, community groups, WhatsApp lists and past clients are strong channels for niche agencies.
B2B partners: if you have trade relationships, a B2B travel portal lets other agents book through you.
Your UK online travel agency launch checklist
Work through these stages in order. Each one has a simple test so you know when it is done.
Plan: Pick a niche, customer group and earning model. Done when: you can describe your customer and product in one sentence.
Company: Register the business, open a bank account, speak to an accountant about VAT and TOMS. Done when: your company number and business account are in place.
Compliance: Check ATOL, package travel rules and ABTA; pay the ICO fee; arrange insurance. Done when: you know whose protection covers each type of booking.
Suppliers: Choose platform suppliers or sign your own GDS and bedbank contracts. Done when: live prices show in test searches.
Website: Brand your booking site, add terms, privacy and protection pages. Done when: test bookings work on a beta site.
Payments: Open a gateway or merchant account and test checkout. Done when: a test payment completes and the confirmation email arrives.
Go live: Switch on your domain, launch marketing, monitor first bookings. Done when: your first real booking is confirmed.
Key takeaways
Order matters: company and compliance first, then suppliers, website and payments.
Protection is not optional: know whether ATOL and the Package Travel Regulations apply to what you sell, and whose protection covers each booking.
Suppliers are the hard part: using a platform's suppliers lets you sell before signing your own GDS or bedbank contracts.
Test before you pay: a free beta site lets you check the whole booking flow, with billing only from go-live.
Start narrow: a clear niche makes marketing cheaper and faster.
Frequently asked questions
Do I need an ATOL to start an online travel agency in the UK?
It depends on what you sell and how. If you sell flights or flight-inclusive packages to UK customers, ATOL rules are likely to apply, either through your own licence or by selling as an agent for an ATOL holder. Check the CAA's guidance or speak to a travel law adviser before selling flights.
Can I start an online travel agency from home?
Yes, many UK agencies start as home-based businesses. You still need the same company registration, protection arrangements, data protection steps and payment setup as any other agency.
Do I need my own GDS contract to sell flights online?
Not necessarily. You can sell through a platform or consolidator that already holds supplier connections. On TravelWhiteLabel, our suppliers are included at no extra cost, and you can connect your own GDS later if you want to.
How much does it cost to launch the website?
It varies by approach. On TravelWhiteLabel there is no setup fee, you start on a free beta site, and plans start at £179 per month once you go live. Our travel booking website cost guide covers build and SaaS costs in more detail.
Is ABTA membership compulsory?
No. ABTA is a voluntary trade association, but many UK customers look for it, and membership brings a code of conduct and protection arrangements for some bookings. ATOL and the Package Travel Regulations are separate legal requirements.
