Services · Mobile app development · Appointment booking apps
Codeeo delivers appointment booking app development UK businesses can roll out from one site to a national network: optician and hearing chains, vet groups, dental and physio providers, salon franchises, car servicing networks and professional firms. Clients book, pay and manage appointments in your own branded app, and head office, regional managers and branches work from one platform built around UK data, consumer and payment rules.
We have no UK office. As an appointment booking app development company UK clients work with remotely, we run discovery, design reviews and sprint demos by video call, and plan each rollout around the nations, regions and towns your network actually covers.

What the platform can include
A national booking app is a different product from a single shop's diary. It has to cope with four nations that share some laws and differ on others, bank holidays that are not the same in Edinburgh, Cardiff and Belfast, regulators that change depending on where a clinic sits, and branches that range from a high street unit to a retail park concession. Head office wants consistency; branch managers want control over their own day.
The capabilities below are the building blocks we use for UK wide networks. Discovery decides which go into the first release, usually a core booking engine, payments and reminders, and which follow as the rollout reaches more sites. Everything runs on one shared platform, so a rule changed at head office applies across the network the same morning.
Clients search by postcode or current location and see nearby branches with opening hours, services offered and next available slot. Postcode lookup uses a licensed UK address service, so addresses for home visits are captured accurately the first time. Clients can save a favourite branch for quicker rebooking.
Clients find the nearest branch with a free slot in seconds.
Bank holidays differ across England and Wales, Scotland and Northern Ireland, and some areas keep local holidays too. Each branch inherits the right calendar for its nation, with overrides for local closures, so nobody books a client into a shuttered branch on St Andrew's Day or the Twelfth.
Opening days are correct everywhere without manual edits.
Head office sets services, durations, prices, deposit policy and brand content once. Regional and branch managers adjust rotas, local promotions and opening hours within limits you define, and every change is logged with who made it. Brand content updates reach every branch at once. Branch overrides expire automatically.
Brand standards hold while branches run their own day.
Deposits, prepayment, stored cards and refunds run through a UK regulated provider, with Strong Customer Authentication applied where card rules require it. Apple Pay, Google Pay and Open Banking pay by bank options can sit alongside cards, and the full price including any fee appears before confirmation. Payouts can be routed to each branch or franchisee.
Payments meet UK card rules without extra steps for clients.
Cancellation and refund terms, distance selling information and any booking fee are shown at the right point in the flow, using wording your legal team approves. Where Scottish law or a regulator's rules require different terms, branches in that nation get their own version. Clients receive a copy of the terms with their confirmation.
Clients see the terms before they pay, every time.
Healthcare providers answer to CQC in England, Healthcare Improvement Scotland, Healthcare Inspectorate Wales or RQIA in Northern Ireland. We design intake forms, consent records, access controls and audit logs that support the regulator each branch actually reports to. Each branch is tagged with its regulator, so forms and retention rules follow automatically.
Records are ready for whichever inspector calls.
Brands with branches in Wales can offer the app in Welsh as well as English, with translated services, booking steps and reminders. Other languages your clients use can be added the same way, each chosen once by the client and remembered. Welsh content is written by translators, not machine output.
Welsh speaking clients can book in their own language.
Confirmations, reminders and recall messages for eye tests, hearing checks, vaccinations or MOTs run on schedules you control. Times are stored correctly across the switch between GMT and British Summer Time, so a reminder never quotes the wrong hour in spring or autumn. Clients can choose text, email or push for each message type.
Clients return when they are due, at the right time.
Utilisation, no-shows, cancellations, rebooking and revenue by nation, region, branch and practitioner, with exports for finance and connections to Power BI or your data warehouse. New branches appear in reports from the day they go live. Regional managers see only their own area. Exports run on a schedule you set.
The network is compared on the same numbers everywhere.
Connections to practice management, ERP, CRM, HR and rota systems, and to Microsoft 365 or Google Workspace calendars, through APIs where they exist. We plan the integration order with your IT team so each branch rollout has the data it needs. Failed syncs alert the IT team before branches notice.
The booking platform fits the systems head office already runs.
Who this is for
Off the shelf booking software works for many single sites. National networks tend to hit its limits: per branch licences that add up, rules that cannot vary by nation, weak reporting across regions, and a client list that sits in someone else's platform. A custom appointment booking app development UK programme gives you one product you control, rolled out in the order that suits your business. These are the networks we hear from most, each with a different first release and rollout order.
Opticians, audiology, dental, physiotherapy and private diagnostic groups operate under different regulators across the four nations and handle special category health data under UK GDPR. We build intake, consent, recall and access rules that suit each regulator, with hosting and retention agreed in discovery. Self pay and insured patients can follow different flows on the same platform. Recalls are set per service and per nation where clinical guidance differs. Clinicians who work across several sites see one combined diary, while each branch keeps control of its rooms and equipment.
Health data handling is planned before any screen is designed.
Salon, beauty, fitness and home service franchises need one brand app with franchisee level control and fair reporting. We build franchisee dashboards, local pricing within brand rules, territory based bookings for home services and royalty friendly revenue reports, so the franchisor sees the network and each franchisee runs their own business. New franchisees can be onboarded from the dashboard without a developer. Brand campaigns can be pushed to every franchise app at once, with local offers layered on top where the franchisor allows.
Car servicing, tyre fitting, appliance repair and cleaning networks book by postcode and technician skill across wide areas. We build territory rules, travel buffers, parts notes and technician apps, with MOT or service recall reminders driving repeat bookings across every region. Customers see a live arrival window on the day of the visit. Technician skills, van stock and coverage areas decide which jobs each person can be offered, so a specialist repair is never booked with someone who cannot complete it on the first visit.
Accountancy, legal, financial advice and recruitment firms with offices across the UK book consultations by video or in person. We build adviser availability across offices, pre meeting questionnaires, identity and document upload where needed, and calendar sync with Microsoft 365. Firms regulated by the FCA or the SRA can keep records in line with their own compliance rules. Office closures and adviser holidays block availability automatically. Clients can choose an adviser they have seen before. Video links are created automatically.
How we work together
Smaller networks often start with a fixed scope first release covering the core booking engine and a pilot region, then move to a retainer for rollout support and new features. Larger groups usually prefer a dedicated team working through a longer roadmap with their IT and operations leads. Cost depends on the number of booking types, user roles, nations and regulators involved, the integrations with existing systems and whether you launch native apps, a web app or both. Migration of existing client records from an old booking system is scoped and priced as its own piece of work, because the quality of that data varies widely between networks.
The appointment booking app developers UK clients meet in discovery stay with the programme through launch and rollout, with full documentation so an internal team can take over at any point.
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
We choose technology to match your estate and your IT team's skills. Typical platforms use Flutter or React Native for mobile, a Laravel or Node backend, a browser dashboard for branches and head office, payments through a UK regulated provider, and hosting in a UK or EU region where your data policy requires it. Single sign on for staff through Microsoft Entra ID or Google Workspace is common for larger estates.

As one platform first, then a rollout region by region.
We start with the rules every branch shares, such as services, payment policy, branding and data handling, and build those into one platform. Nation specific calendars, terms and regulator requirements are layered on top. A pilot region goes live first, and the remaining branches follow in waves with staff training, so problems are found while they affect a few sites rather than the whole network. The first wave is usually chosen for a mix of busy and quiet branches, so the platform is proven under both conditions.
