Services · Mobile app development · Field service management apps
Codeeo delivers field service management app development UK operators use to run national workforces: a mobile app for engineers, scheduling for regional planners, portals for clients and reporting for head office. We build for firms whose people work from Cornwall to the Highlands, where a single contract can cross English, Scottish, Welsh and Northern Irish rules, and where rural signal, long drives and lone working are part of an ordinary day.
Our team of 80+ works from Dubai, Riyadh and Karachi and works remotely with UK clients, running discovery and reviews by video call. We have delivered 200+ projects across the UAE and the US and hold a 4.7 rating from 23 Google reviews.

Platform capabilities
Running engineers across the whole country raises problems a single city operator never meets. Housing standards and tenancy law differ between England, Scotland, Wales and Northern Ireland, bank holidays do not line up, and clients increasingly expect one national report even when the work was done by four regional teams. Engineers in the Pennines, mid Wales or the Scottish islands lose signal for hours. Lone working policies, the Working Time Regulations and HSE expectations apply wherever they are. On the commercial side, UK GDPR governs how you track people and store customer data, PECR governs the texts and emails you send, and HMRC's Making Tax Digital shapes how invoices reach your accounts. A national platform has to handle all of that while staying quick enough that an engineer closes a job in a minute or two. We design the data model and permissions for scale first, then add the capabilities below in phases that match your rollout plan.
Your organisation is modelled as regions, depots and teams, each tagged with the UK nation it operates in. Forms, timescales, certificates and bank holiday calendars follow that tag, so a repair in Cardiff applies Welsh rules while the same job type in Glasgow applies Scottish ones. Teams that cross a border, such as engineers based in Chester covering north Wales, simply follow the property's tag.
One platform that respects four sets of rules without four separate systems.
Large clients such as retailers, housing groups and estates managers sign one contract covering hundreds of sites. The platform holds the contract, its regional schedules, SLAs and pricing, and rolls every job up into a single national view for the client's account manager.
Clients see one service, however many regional teams deliver it.
Engineers working alone confirm arrival and departure, and the app prompts a check in if a job runs well past its expected length. Missed check ins escalate to a supervisor by text and call, with the engineer's last known location, following the procedure in your lone working policy.
Supervisors know quickly when an engineer in a remote area needs help.
Jobs, asset records, forms and manuals for the whole day are stored on the device. Engineers working without coverage complete everything as normal, and the app syncs in the background once a signal returns, with clear indicators showing what has and has not reached the office.
Rural coverage stops being a reason for paper backups.
Shift lengths, rest breaks, on call rotas and weekly hours are tracked against limits you set to reflect the Working Time Regulations and your own policies. Planners see warnings before scheduling an engineer who would exceed them after a long overnight callout.
Fewer tired engineers on the road after an emergency night.
Parts move from a central warehouse to vans, depots or collection lockers overnight. The platform reserves stock against jobs, chooses the nearest delivery point for each engineer, and tracks returns of faulty or unused parts so national inventory stays accurate.
Engineers in every region start the day with the parts they need.
Residents and business customers book, reschedule and track visits through a portal designed to WCAG 2.2 AA, supporting screen readers, keyboard use and clear contrast. That matters for duties under the Equality Act and for clients in housing and public services who audit accessibility.
Customers of every ability can manage their own appointments.
Engineers take card payments on site or send pay by bank requests using Open Banking. Business invoices flow to Xero, Sage or Business Central with VAT handled in a way that fits Making Tax Digital, and Construction Industry Scheme details are recorded for subcontracted work.
Cash collected faster, with less work for regional finance teams.
Dashboards compare first time fix rates, SLA performance, travel time, overtime and job margin across regions and contracts. Data can be exported to Power BI or your own warehouse, so operations directors can find which region or job type needs attention.
Decisions based on comparable figures from every region.
Who this is for
Packaged field service products work well for many single region firms, and we will tell you if one meets your needs. Custom Field service management app development UK organisations commission usually pays off when the operation spans several nations, contract types or workforce models that a template forces into an awkward shape. The four profiles below are where a tailored platform tends to earn its keep. For each one we note what the first release usually covers, although your contracts and clients will decide the final scope.
Firms maintaining shops, banks, offices and public buildings across the country carry national contracts with regional delivery, and their clients expect identical reporting everywhere. We build the contract hierarchy, national SLA reporting and regional planning boards first, then add asset registers and planned maintenance. Regional managers keep control of their teams while head office sees the whole estate.
Contract structure is usually the hardest part to get right, so we design it first.
Housing repairs rules differ across the UK. England has Awaab's Law and the Regulator of Social Housing's consumer standards, Scotland has its own housing standards and regulator, and Wales has the Renting Homes framework. A contractor working for landlords on both sides of a border needs workflows and timescales that follow the property, not the engineer. We configure those rules per nation and per client.
We confirm the rules with your clients' policies rather than assuming them.
Organisations installing meters, broadband connections, heat pumps or chargers run high volumes of short jobs with strict evidence requirements from clients, networks or certification schemes. They need fast job completion, photo rules that enforce what must be captured, and integration with client systems that issue and close the work orders.
Evidence rules are enforced by the app so rework requests fall.
Companies that sell machinery, medical devices, catering equipment or lifts often service it nationally with their own engineers and approved partners. They need warranty and contract tracking, serial number history and a partner portal, so third party engineers use the same forms and the manufacturer keeps one record of every installed unit across the UK.
Partner engineers get a restricted login with your forms and branding.
How we work together
National programmes usually start with a fixed scope first release and pilot, followed by a dedicated team for the rollout waves and new modules. Smaller organisations often move to a monthly support and development plan after launch. A field service management app development company UK operators trust with a national system should be easy to hold to account, so you get a shared task board, written decisions after each video call and clear ownership of every deliverable.
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
Engineer apps are built in React Native or Flutter with offline storage, scanning and secure background sync. Back ends use Laravel or Node with message queues for high volumes, hosted in UK regions on Azure or AWS. We integrate with Dynamics 365, Business Central, Xero, Sage, HR systems and client work order platforms.

02Data and cloud
03Marketing and tracking
We agree timing after discovery, with separate dates for the first release and each rollout wave.
The size of the first release, the number of integrations and how many regions or nations are involved all shape the timeline. A national operator might launch core scheduling and job completion in a pilot region, then add contracts, analytics and partner access while other regions migrate. We write every phase into the scope with its own dates and share test builds throughout, so your board sees steady progress rather than one large launch.
