Services · Mobile app development · Travel agency apps
Travel agency app development UK firms can rely on starts with the rules, not the screens. We build customer apps, consultant tools and admin systems for travel agents, homeworker networks and tour operators across Britain. Quotes, packages, deposits, balance reminders, ATOL paperwork and supplier bookings sit in one system, so a holiday sold in a branch, by phone or on a phone screen follows the same compliant process and every traveller can find their documents when they need them.
An app cannot make a business ATOL holder or an ABTA member. What it can do is make sure the protections you already offer are recorded, shown to the customer at the right moment and easy to prove later if a supplier fails or a complaint arrives. It also gives customers one place for the whole trip.

Features we build
Selling holidays in Britain means working inside a specific set of rules. The Package Travel and Linked Travel Arrangements Regulations 2018 decide when you are the organiser of a package and what you owe the traveller. The Civil Aviation Authority runs ATOL for flight-inclusive sales. ABTA members follow its Code of Conduct. Since April 2025 the Digital Markets, Competition and Consumers Act lets the CMA fine businesses directly for unfair practices such as drip pricing. UK GDPR, overseen by the ICO, covers passport and health details, and PECR governs your marketing emails and texts.
The features below are the ones we see UK agents and operators ask for most. We build them so the regulated steps happen automatically inside normal selling, rather than relying on a consultant remembering a checklist on a busy Saturday. Good travel booking app development UK customers actually use also means fast search on a weak signal and a checkout that never surprises them.
Consultants assemble flights, hotels, transfers and extras into a quote the customer can open on their phone, compare against alternatives and accept with one tap. Each component keeps its supplier reference, so the quote converts into a booking without anyone retyping details or losing the price that was agreed on the call.
Quotes reach customers faster and convert without rekeying.
When a basket combines travel services, the system works out whether you are creating a package, a linked travel arrangement or separate bookings, using rules your compliance lead signs off. The correct pre-contract information form is then shown and stored, with a timestamp, against that customer and booking.
The right Package Travel Regulations paperwork, every time.
For flight-inclusive sales the app generates or attaches the ATOL certificate at the point the scheme requires, records which ATOL holder protects the booking and sends the customer a copy they can open offline. Agents selling as an agent for an ATOL holder see that relationship clearly in the record.
Proof of protection held for every flight-inclusive booking.
Customers pay a deposit by card or bank transfer, see what is owed and when, and receive balance reminders before the due date. Card payments run through Strong Customer Authentication, and pay by bank through Open Banking can sit alongside cards where your payment provider supports it. Client money can be tracked against trust account rules if you use one.
Fewer chased balances and clear records of customer money.
We connect to the sources you already contract with: GDS access for flights, airline NDC content, bedbanks, tour operator systems, cruise lines, rail and transfer providers. Availability and pricing are checked live where suppliers allow it, and bookings are written back to your back office so stock and records match.
Live availability without switching between supplier portals.
Mandatory charges such as booking fees, resort fees and card surcharges are added to the first price a customer sees, not the last. Optional extras stay optional and are listed clearly. This keeps your displayed prices in line with the DMCC Act drip pricing rules and the CMA's price transparency guidance.
Headline prices that match what the customer pays.
Tickets, vouchers, ATOL certificates, insurance details and the itinerary sit in one place in the app, available without signal. Passport and health information is collected only where a booking needs it, encrypted, limited to the staff who must see it and removed on the schedule set out in your privacy notice.
Travellers stop phoning the office for lost paperwork.
Homeworking agents and branch staff share one booking platform with role based access, commission tracking and head office oversight. A network can see sales by consultant, flag bookings that miss a compliance step and push updated supplier terms to everyone at once, without separate spreadsheets for each member.
One standard across every branch and homeworker.
When a flight changes, an airport strikes or Foreign, Commonwealth and Development Office advice shifts for a destination, the team sees which customers are affected and can message them in the app. Customers already abroad get clear next steps and a way to reach a person.
Problems handled before the phones start ringing.
Customers choose what they hear about and how, and those choices travel with their record. Marketing emails, texts and push messages respect PECR, and a customer who withdraws consent drops out of every campaign at once rather than one list at a time. Preference changes made in a branch update the app record too.
Marketing that stays on the right side of the ICO.
Who we build for
Travel selling in Britain is spread across very different business models. A family-run agency on a high street, a network of several hundred homeworkers, a specialist tour operator and a fast growing online brand all face the same regulators but need different tools. These are the four starting points we see most, and how the first version of the app differs for each. Holiday booking app development UK families respond to looks different again from a trade tool used by consultants all day.
Your customers know your staff by name and still want that relationship when they book on a phone. We usually start with a client app for quotes, payments and documents, connected to the back office you already run, so consultants keep their way of working and customers get a modern place to manage their trip. Later releases add self-serve extras such as seats, parking and lounges. We also add a simple way for customers to message the branch, so questions arrive with the booking reference already attached.
Start with what your regulars ask for most.
Head office carries the ATOL and the trading terms, while hundreds of members sell under them. The platform has to enforce the same booking rules everywhere, pay commission correctly and give compliance staff a view across the whole network. We plan permissions, onboarding and member reporting before customer features. Member onboarding includes identity checks, training records and acceptance of network terms, all stored centrally. Head office can suspend a member's selling rights instantly if a compliance issue appears, without touching anyone else's bookings.
Network rules come first, branding second.
As the organiser you carry full responsibility for the package under the 2018 regulations. Your app needs departure inventory, rooming lists, supplier contracts, manifests and traveller communication in one place. Many operators also sell through agents, so we build a trade portal beside the consumer app with net pricing and agent commission. Pre-departure information, emergency contacts and itinerary changes reach travellers directly, which matters because the organiser must help travellers in difficulty during the trip. Supplier contracts and allocations are stored with release dates, so unsold rooms go back on time.
Organiser duties shape the whole data model.
You already sell on the web and want an app that keeps customers coming back. We focus on fast search, saved trips, price alerts within consent rules and a checkout that is quick without hiding mandatory costs. Supplier connections and caching are planned for peak demand, such as the January booking rush. We also review how your existing web booking engine stores customers, so accounts and past bookings carry over into the app. Analytics are set up within consent rules to show where people drop out of search and checkout.
Peak traffic planning starts in discovery.
Working with Codeeo
Codeeo has delivered 200+ projects across the UAE and the US, with a team of 80+ across Dubai, Riyadh and Karachi, and is rated 4.7 from 23 Google reviews. We have no UK office; our team works remotely with UK clients, and discovery, design reviews and sprint demos all run by video call. Most travel firms start with a fixed scope first release, then keep the app moving on a monthly retainer. Networks and operators with a long roadmap sometimes take a dedicated team instead. Unlike travel app developers UK firms may have tried before, we write the compliance steps into the scope rather than leaving them for the end.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
Native or cross-platform apps, a web admin, and APIs chosen to suit your suppliers, your payment provider and the back office system your accounts team already depends on. Hosting region and backups are agreed with you, so booking and customer data stay where your privacy notice says they are.

The app records protection; your licence or principal provides it.
ATOL is granted by the Civil Aviation Authority to a business, not to software. If you hold an ATOL, or sell as an agent for an ATOL holder, the app applies the rules you operate under: it identifies flight-inclusive bookings, issues or attaches the certificate when the scheme requires, and stores evidence of what the customer received. We take those rules from your ATOL documentation and your compliance lead, and we do not offer legal advice on whether a product needs protection.
