Services · Mobile app development · AI apps
Codeeo provides AI app development UK organisations can defend in front of a regulator, an auditor or a customer complaint. We build mobile and web apps with language, vision and prediction features, and we design them around the UK's sector led approach to AI, UK GDPR as amended by the Data (Use and Access) Act 2025, and the accessibility duties of the Equality Act.
We have no UK office. Our team of 80+ in Dubai, Riyadh and Karachi works remotely with clients from Aberdeen to Plymouth, running discovery, design reviews and release demos by video call, which also suits organisations spread across several UK sites.

What a UK wide AI app needs
The UK has no single AI statute. Instead, existing regulators apply shared principles of safety, transparency, fairness, accountability and contestability within their own sectors. The ICO covers personal data, the FCA covers financial services, the MHRA covers software that acts as a medical device, Ofcom enforces the Online Safety Act, and the CMA looks at competition and consumer protection. An AI app that serves customers nationally may touch several of them at once. Cyber Essentials expectations from public sector buyers, and the security questions larger customers send, are considered in the architecture from the start.
That shapes what we build. Alongside the features users see, a UK wide app needs governance features that let you prove how it behaves: model registers, evaluation records, consent handling and clear routes to human review. The capabilities below combine both, and we select them according to your sector, your users and the nations you operate in. Cyber Essentials expectations from public sector buyers, and the security questions larger customers send, are considered in the architecture from the start.
Customer and staff assistants grounded in your own approved content, with guardrails tuned to your regulator. A financial firm's assistant avoids anything resembling personal advice unless authorised; a health app's assistant routes symptoms to clinical pathways; a retailer's assistant follows consumer law on pricing and returns.
Answers stay inside the lines your regulator draws.
An admin record of every model, prompt and version in use, what it is for, who approved it, how it was tested and when it changed. Each output that matters is logged against the version that produced it, ready for an internal audit or a regulator's request.
You can show exactly what the app did and why, months later.
Where the app supports decisions with legal or similarly significant effects, users can see the main reasons, add information and ask for a person to reconsider. Review queues, deadlines and outcomes are tracked so the safeguards required for automated decision making are real rather than nominal.
Customers can challenge outcomes and your team can respond on time.
Integration with certified digital identity providers under the UK digital identity and attributes trust framework, plus age assurance where the Online Safety Act or your own policies require it. Document and face checks use providers whose data handling you have reviewed.
Onboarding is fast and fits UK identity standards.
Pay by bank, Faster Payments, Direct Debit, Apple Pay and Google Pay, with AI used where it helps: categorising transactions, spotting affordability concerns or flagging unusual activity for review. Payment data stays with regulated providers and the app only stores what it needs.
Payments feel familiar to UK users and stay secure.
Public bodies in Wales have Welsh language duties, and many UK customers prefer another language at home. We support Welsh interfaces and machine assisted translation with human review where accuracy matters, keeping a reference version for legal and safety text.
Users across the four nations get answers they understand.
For health and care apps we structure hazard logs and safety evidence to support DCB0129 and DCB0160, prepare for the NHS Digital Technology Assessment Criteria, and plan around MHRA guidance on software and AI as a medical device when your intended purpose brings the app into scope.
NHS buyers see the evidence they expect from day one.
Streamed answers announced correctly to screen readers, voice input, adjustable text size and plain language summaries, built and tested against WCAG 2.2 AA. Public sector clients also need an accessibility statement, which we help prepare from the test results.
Disabled users can rely on the AI features as much as anyone.
Hosting in UK cloud regions, model providers chosen for their data terms, and documented transfer assessments where any processing happens abroad. Sensitive workloads can run on open weight models inside your own tenancy.
Procurement and data protection questions have clear answers.
Configuration by region or branch, so a feature can pilot in Leeds before reaching Glasgow or Cardiff. Usage, accuracy and override rates are compared across sites, showing where local processes or data differ.
Rollouts proceed on evidence, one region at a time.
Who this is for
Nationwide projects bring problems a single city build never meets: different legal systems in Scotland and Northern Ireland, Welsh language expectations, regional data quality, and stakeholders in several offices. The organisations below are those we are best placed to help. All of them benefit from a remote delivery model, because their own teams are already spread across the country and used to working by video call. They also tend to have central IT, data protection and procurement functions that must approve a supplier before any regional team can pilot something new, so we prepare that paperwork early.
Retailers, gyms, estate agency networks and franchise groups want AI features that behave consistently in every branch. Custom AI app development UK chains commission from us typically covers customer assistants, staff knowledge tools and demand forecasting per site. We respect the Digital Markets, Competition and Consumers Act 2024 rules on fake reviews and drip pricing, and PECR rules on marketing consent, when AI writes or personalises customer messages. Head office keeps control of brand voice and policy content, while regional managers add local details such as opening times and services.
Branch managers can see and correct what the AI tells their customers.
Lenders, insurers, wealth platforms and payment firms face the Consumer Duty, SM&CR accountability and operational resilience rules. We build AI features with named owners, documented testing, fair outcome monitoring across customer groups and human review where decisions affect people's finances. If you want to use FCA support for AI testing, we can help prepare the product and its evidence. Monitoring includes checks that customers in vulnerable circumstances are not receiving worse outcomes from automated features.
From private clinics to suppliers selling into NHS trusts and integrated care boards, health organisations need AI that supports clinicians rather than quietly replacing them. We plan the intended purpose carefully, since it decides whether MHRA medical device rules apply, and we design for CQC expectations on safe care when the app is used in a registered service. Integration with NHS login or clinical systems is scoped separately, because each has its own onboarding and assurance steps.
Your clinical safety officer owns the safety case; we supply the evidence.
Many UK start ups plan to sell into the EU, where the EU AI Act applies to systems placed on that market. AI mobile app development UK founders ask us for often includes architecture that can meet both UK principles and EU obligations, such as risk classification, technical documentation and transparency notices, without building two products. We also keep your investors' due diligence in mind, since data rights and model ownership are now standard questions.
One codebase, documented for two regimes.
How we work together
National organisations often start with a discovery and regulatory mapping phase, followed by a fixed scope first release for the pilot region. After that, a retainer covers rollout support, evaluation runs, new features and model updates. Groups with a long roadmap may prefer a dedicated team working within their own governance. If you are shortlisting an AI app development company UK procurement teams can assess properly, we provide documentation, security questionnaire answers and a description of our delivery approach in writing, and we explain upfront that all delivery is remote. Public sector suppliers can ask us to structure documentation to match the buyer's assurance checklist.
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 iOS and Android or cross platform apps, hosted and open weight language and vision models, retrieval systems, and UK region cloud hosting, chosen to fit your security policies, vendor risk rules and long term running costs.

Through existing laws and sector regulators rather than one AI act.
The government's approach asks regulators such as the ICO, FCA, MHRA, Ofcom and CMA to apply common AI principles within their remits. In practice that means UK GDPR for personal data, consumer and competition law for customer facing features, the Online Safety Act for user content, and sector rules for finance and health. We map these for your use case at the start, so the app is built to them rather than reviewed against them at the end. Because the approach keeps developing, we review the map at each major release.
