Services · Mobile app development · Ecommerce apps
Codeeo delivers ecommerce app development UK retailers can roll out nationally: iOS and Android shopping apps with a shared catalogue, compliant checkout, nationwide delivery, store collection and loyalty. We plan each app around UK consumer law, UK GDPR, strong customer authentication and the carriers your customers already know, so it works the same way for a shopper in Cardiff, Glasgow, Belfast or Norwich.
Our team of 80+ is based in Dubai, Riyadh and Karachi and has delivered 200+ projects across the UAE and the US. We work with UK clients remotely, running discovery, reviews and demos by video call and confirming every decision in writing.

Built for UK-wide retail
Selling across the UK means one app has to satisfy several sets of rules and expectations at once. Consumer contracts, distance selling cancellation rights and the consumer protection changes that took effect in April 2025 shape what the checkout and order screens must show. UK GDPR and PECR govern accounts, tracking and marketing messages, with the ICO as regulator. Payment rules from the FCA regime require strong customer authentication. Then there is geography: next day delivery promises that work in Bristol may not hold for the Scottish Highlands or the islands, and goods heading to Northern Ireland follow their own arrangements since Brexit.
The capabilities below cover those national requirements first, then the retail features that drive repeat sales. We scope them so the first release can launch in your strongest region and extend to others without rework.
Total prices including mandatory charges shown from the start, clear delivery costs, pre-contract information, order confirmation by email and an easy route to cancel within the statutory period for distance sales. The DMCC Act rules on drip pricing and fake reviews are reflected in how prices and ratings appear across the app. Subscription sign-ups get clear renewal information and a simple way to cancel.
Checkout screens that stand up to scrutiny from the CMA and Trading Standards.
Separate opt-ins for push notifications, email, SMS and personalised advertising, with a preference centre customers can change at any time. Analytics and advertising SDKs only load once consent rules allow it. Every choice is logged with a timestamp so you can show what was agreed and when. Deleting an account removes or anonymises personal data in line with your retention policy.
Marketing reach built on consent the ICO would recognise.
Cards with strong customer authentication handled inside the app, Apple Pay and Google Pay, pay by bank through Open Banking providers, gift cards and pay later options through your chosen provider. Failed authentications are retried gracefully instead of losing the basket. Refunds go back through the original method, with status visible in the order history.
Fewer abandoned payments at the final step.
Integrations with the carriers you use, such as Royal Mail, DPD, Evri or Parcelforce, with different services and cut-off times by postcode area. Remote areas, offshore islands and Northern Ireland can carry their own delivery promises, so customers see a date that matches where they live. Customers can also choose a named day or an evening slot where your carrier offers one.
Honest delivery dates everywhere in the UK.
Customers choose a parcel locker, a convenience shop pickup point or one of your stores on a map, filtered by distance from home or work. Tracking updates and collection codes arrive as notifications, and unclaimed parcels trigger reminders before they are returned. Locker and pickup networks are shown together, so customers compare by distance rather than brand.
Delivery that suits people who are rarely home.
A store finder covering every branch, opening hours, services and live stock for each location. Customers reserve an item in a branch in another city before travelling, and staff see the reservation on a handheld device. Branch staff can mark a reservation ready or release it back to stock from the same device.
Online browsing that sends customers to the right store.
Screens built to WCAG 2.2, with screen reader labels, scalable text, sufficient contrast and touch targets large enough for everyone. The Equality Act 2010 expects services not to put disabled customers at a disadvantage, and an accessible app also converts better for everyone else. We test with VoiceOver and TalkBack before each release, not only with automated tools.
An app every customer can use, with less legal risk.
For retailers with a strong presence in Wales, product pages, navigation and notifications can be offered in Welsh alongside English, with content managed through the admin platform rather than hard-coded strings. Language preference carries through to emails and receipts as well as the app screens.
Welsh-speaking customers served in their own language.
One membership across app, website and every store, with tiers, personalised offers and rewards redeemed at any till. Regional campaigns can target customers near particular stores without fragmenting the programme. Members can see their history and rewards wherever they shop, online or in person. Points balances update in near real time after each purchase.
A single customer view across the whole country.
Connections to your ERP, warehouse management, EPOS and customer service tools, so prices, stock, orders and returns stay consistent. We document each integration and add monitoring so failures are spotted before customers notice. Where a legacy system lacks an API, we agree a scheduled file exchange as an interim step.
The app reflects what your business systems say.
Who this is for
A national app is a different project from a single-city one. The questions are about rollout order, consistent data across many stores, regional delivery promises and legal requirements that apply everywhere. These are the four types of business we see most often, with the first release that usually makes sense for each. Scotland has its own legal system, so we check with your advisers whether any terms or notices need different wording for customers there. We also consider how the app sits alongside your website, contact centre and stores, because a national customer expects all of them to recognise the same account.
For a chain spread from Aberdeen to Plymouth, the hardest part is data: accurate stock in every branch, consistent prices and one loyalty account. We usually launch with store stock, reservation and loyalty in a pilot region, monitor accuracy and staff adoption, then roll out region by region. Home delivery features follow once stores trust the data. Central merchandising teams control national campaigns, while store managers handle local events. Store staff training is planned region by region so every branch is ready before its launch date.
A pilot region exposes data problems before they reach every store.
Brands that sell mainly online across the UK need fast checkout, accurate delivery dates for every postcode, returns that are easy to start and a reason for customers to come back. The first release focuses on those, with consent-based push notifications and loyalty designed to bring buyers back without breaching PECR. Courier choices at checkout let price-sensitive and time-sensitive customers each pick what suits them. Reviews collected after delivery are checked so only genuine purchasers can post. Product pages can show size and fit feedback from verified buyers, which supports conversion.
Repeat purchases are the case for the app.
If you run a marketplace connecting independent sellers with buyers across the country, the app needs seller onboarding, listings, order routing to the right seller, split payments through a regulated provider and a fair reviews system. Under the DMCC Act, the way reviews are collected and shown carries real legal weight, so we design that flow carefully. Seller dashboards show orders, payouts and performance so sellers can manage their own shops. Seller verification steps help keep counterfeit or unsafe goods off the platform. Disputes between buyers and sellers are handled through a clear, logged process.
A retailer strong in one region, perhaps Scotland or the North East, often wants to sell across the UK before opening stores elsewhere. The app introduces nationwide delivery and a brand presence beyond the home region, while keeping local stores at the centre of the experience for existing customers. Delivery zones can widen in stages as fulfilment capacity grows. Stock held in regional warehouses can be allocated to national orders without starving local stores. A national customer base also justifies investment in carrier integrations and a proper returns process.
How we work together
A fixed scope project covers the first release, with features, deliverables and phases agreed before work starts. Once live, a retainer handles updates, regulatory changes, seasonal campaigns and new features. Larger retailers with internal product teams often add a dedicated team of our designers and developers working inside their own planning cycle. All three keep ownership of code, data and accounts with your company, and each phase is agreed in writing before it begins. Rollout across regions can be paced to your own budget cycle and trading calendar.
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 the stack around your existing ERP, EPOS, ecommerce platform and payment provider, and around who will maintain the app in future. Cloud hosting sits in your own account, with data location agreed during discovery to fit your UK GDPR obligations. Handover documentation is part of every phase.

03Marketing and tracking
Consumer law, data protection, marketing consent, payments and accessibility.
The app must show clear prices and pre-contract information, respect cancellation rights for distance sales, follow UK GDPR and PECR for data and marketing, apply strong customer authentication to card payments and meet accessibility expectations under the Equality Act. We map each requirement to a feature in discovery and flag where your own legal advisers should review wording. We do not give legal advice ourselves, but we make sure the app can carry whatever your advisers decide.
