Services · Mobile app development · On-demand staffing apps
Codeeo offers staffing app development in the UK for employment businesses, shift marketplaces, staff banks and licensed labour providers. We build worker apps, client portals and back-office systems that carry the national rulebook: the Conduct of Employment Agencies and Employment Businesses Regulations, the Agency Workers Regulations, Home Office right to work checks, working time limits and HMRC reporting. The result is one platform that fills shifts across many branches and keeps evidence ready for any inspector who asks.
We work remotely with UK clients, with discovery, design reviews and release demos held by video call. The code, data and app store accounts are registered to your company, and the documentation is written so another team could take the platform over if you ever choose to.

Capabilities for national operators
A UK staffing business answers to several regulators at once. The Employment Agency Standards Inspectorate enforces the Conduct Regulations. HMRC enforces the minimum wage, PAYE and intermediary reporting, and since April 2026 can pursue agencies for unpaid PAYE where an umbrella company in the chain fails to pay. The Home Office enforces right to work duties with civil penalties. The ICO oversees how worker data is handled under UK GDPR, and the Pensions Regulator oversees auto-enrolment.
Sector and nation add further layers. Vetting runs through the DBS in England and Wales, Disclosure Scotland and AccessNI. Care services are inspected by the CQC, the Care Inspectorate, Care Inspectorate Wales or the RQIA. Food, agriculture and shellfish work needs a GLAA licence. Northern Ireland has its own version of the agency regulations. The capabilities below are how a national platform keeps all of that straight while coordinators simply book shifts.
Each worker is linked to how they are engaged and paid: your own PAYE, an umbrella company or a limited company. Umbrella providers carry due diligence records, accreditation status and payment checks, which matter far more now that the agency can be held liable for PAYE an umbrella fails to pay.
Every payment route is documented and reviewable.
Employment intermediaries must send HMRC regular reports on workers they supply who are not paid through their own PAYE. The app compiles the required fields from booking and payment data, flags missing details early and produces the report file for your finance team to submit.
Reports built from live data, not a scramble each quarter.
A role in Leeds needs a DBS check, the same role in Glasgow needs PVG membership and in Belfast an AccessNI certificate. The app applies the right requirement by the location of the shift, stores results with their dates, and blocks bookings when the matching check is missing.
One worker profile, the right check for each nation.
Branches own their clients and coordinators, regions roll up reporting, and brands can share a worker pool while keeping separate invoices and terms. National accounts book across every branch from one client portal, with rate cards that vary by region and role.
Local teams keep control while head office keeps sight.
Digital checks through a certified identity service provider for British and Irish passports, Home Office online checks for eVisa holders, and the Employer Checking Service where status is pending. The app schedules follow-up checks automatically for anyone with time-limited permission.
Follow-up checks never depend on someone remembering.
Hours approved by the client or confirmed by clock data pass to your payroll provider, which runs PAYE, reports in real time to HMRC and handles auto-enrolment. Payment can go out by Faster Payments the same day the run completes, and workers see a summary that matches the payslip.
Workers paid on verified hours, with a clean audit trail.
The system counts qualifying weeks for each worker and hirer under the Agency Workers Regulations, shows day-one rights in the app, and holds comparator pay details supplied by hirers so rates change on the correct date across every branch.
Equal treatment applied consistently at national scale.
Retention rules delete identity documents and old applications when their purpose ends, criminal record data sits behind tighter permissions, access is logged, and subject access requests can be answered with a single export. The Data (Use and Access) Act 2025 changes are reflected in how any automated matching is explained to workers.
UK GDPR duties handled inside the system.
Screens are designed to WCAG 2.2, with readable text sizes, screen reader labels and simple language. The Equality Act expects reasonable adjustments, and the app lets workers record the adjustments they need so coordinators can arrange them with clients.
More people able to sign up and work.
Clients can settle invoices by Open Banking payment directly from the portal, with remittance matched to the invoice automatically. Credit control sees which clients pay late, which matters because worker pay cannot be held back while you wait.
Faster cash collection without card fees on large invoices.
Who this is for
The national picture rewards operators who standardise. A business with branches in several regions usually runs a different mix of tools in each one, with checks recorded in different ways. Temporary staffing app development in the UK at that scale is mostly about one set of rules applied everywhere, with local flexibility only where the law or the client genuinely differs. These are the four profiles that bring us national work.
Operators often ask whether to build or buy. Off-the-shelf staffing software suits many agencies well. A custom platform earns its place when your model, your sectors or your mix of nations do not fit the packaged products, or when the workflow itself is what sets you apart from competitors.
You run branches across several regions, each with its own spreadsheets and habits. Head office cannot see fill rates, compliance gaps or margins in one place. We build a single platform with branch-level control, a shared worker pool, national client accounts and consistent compliance records, then migrate branches in planned waves so trading never stops.
Migrate branch by branch, never all at once.
You are building a national platform matching businesses with flexible workers. Worker status is the question that shapes everything: employment business, introductory agency or marketplace. Courts look at what really happens, not the label. We build to the model your lawyers choose and keep the rules configurable, so the product can adapt if that model needs to change.
You run an internal bank or a care staffing business working across more than one nation. Vetting, inspection bodies and registration rules differ between England, Scotland, Wales and Northern Ireland. We build role matrices per nation, continuity features for residents and patients, and records that inspectors and commissioners can review without extra paperwork.
You hold a GLAA licence and supply pickers, packers and processors to farms and food businesses around the country, often with shared transport and accommodation. Licence standards look closely at pay, deductions, transport and treatment. We build records for each of those, plus seasonal onboarding and multi-site crews that follow the harvest.
Licence standards should shape the data model.
How we work together
Shift booking app development in the UK at national scale is rarely one project. Most clients start with a fixed-scope first release and a pilot branch, then move to a retainer or a dedicated team for the rollout and the steady list of improvements after it. Our team of 80+ across Dubai, Riyadh and Karachi works with UK clients remotely, and every session runs by video call with written scope and acceptance notes.
For on-demand staffing app development in the UK we also plan for change in the rules. Agency and employment law shifts regularly, so compliance logic sits in configurable settings that your team can update, with our support, rather than buried in code.
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
Typically a cross-platform worker app, web portals for clients and head office, and UK-hosted cloud infrastructure, connected by documented APIs to payroll, identity and accounting services. We choose tools your own developers can maintain after handover, and we build in monitoring so problems at a busy branch on a Monday morning are seen before workers report them.

Agency conduct rules, agency worker rights, right to work, tax and data protection.
The Conduct Regulations govern terms, the Key Information Document, information sharing with hirers and pay. The Agency Workers Regulations govern equal treatment. Home Office rules govern right to work checks, HMRC governs PAYE, the minimum wage and intermediary reporting, and UK GDPR governs worker data. Sector rules such as GLAA licensing and care regulation sit on top. We map which ones apply to your model in discovery.
