React Native Development Company in London

QServices is a remote-first software consultancy based in India. We are not headquartered in London, but we work with UK clients across FinTech, Insurance, Legal, and Media on React Native development engagements with 3.5 to 4.5 hours of GMT morning overlap each day. Our full services portfolio is available to London-based teams on the same remote model.

What London buyers typically need from React Native development

London's mobile app market is shaped by regulated industries. The projects we see from UK-based companies tend to follow recognisable patterns:

• FinTech apps under FCA oversight, open banking integrations, payment UIs, and client-facing investment dashboards where Financial Conduct Authority rules govern what data you can display and how user consent must be captured and stored.
• Insurance platforms subject to PRA requirements, policy management apps, claims submission flows, and broker tools for firms regulated by the Prudential Regulation Authority, where change management documentation is expected before any production release.
• Legal sector client portals, matter tracking, secure document sharing, and client communication tools where UK GDPR obligations under the Data Protection Act 2018 are non-negotiable from day one of the build.
• Media and publishing apps, subscriber management, content delivery, and live event apps where cross-platform reach matters more than a native-only approach can justify on the budget.

UK GDPR applies across all four sectors. FCA and PRA-regulated firms carry additional obligations around audit trails, data residency, and release approval processes. We address those constraints in the scoping document before a line of code is written, not as change orders after delivery.

How we work with London clients

Our team is in India (IST, UTC+5:30). London runs on GMT in winter and BST (UTC+1) in summer. That produces 3.5 to 4.5 hours of real-time overlap in London's morning: roughly 8am to 12:30pm GMT maps to 1:30pm to 6pm IST. We schedule standups, sprint demos, and design walkthroughs inside that window.

Outside overlap hours we work asynchronously. Before the team signs off each day, we post a written summary to the shared Slack or Microsoft Teams channel, what shipped, what is in review, what is blocked. The London side wakes up to a record rather than silence. Code reviews are opened before our day ends and picked up first thing by our team the following morning.

We do not have a London office. For major milestones, end of a build sprint, pre-launch sign-off, we can arrange an on-site visit if the project scope makes it worthwhile. Most London clients have found the daily overlap window sufficient for delivery. We are direct about the trade-off: if you need someone in the room every week, that is worth discussing before either side commits.

Relevant work in similar markets

Neither of our published React Native case studies comes from a London-based client. We say that plainly rather than imply otherwise.

The closest relevant work:

• My Delivery, last-mile logistics app: A React Native and React.js platform for a delivery business, integrating eLogi for driver assignment and Zoho for invoice generation, with two-factor authentication for driver access. The third-party API integration, authentication requirements, and traceable action audit trail on this build share structural patterns with FCA-adjacent mobile apps where every user action needs to be attributable.
• Equalution, nutrition and body transformation platform: A dual-app build combining a React.js dietician web app and a React Native mobile app for clients, with ML-driven personalised calorie targets. Sensitive personal health data, role-based access between two user types, and careful data handling, the same structural concerns that come up in FinTech and Insurance mobile builds.

If your London project is in FinTech or Insurance, the relevant question is whether we understand regulated-data mobile apps, not whether we have shipped one with a UK postcode. Both projects above involved authentication, third-party integration, and data that users expect handled carefully. That transfers.

What React Native development costs for a typical London project

We price in USD. Currency conversion is your team's concern, not ours, but at current rates our work sits below London-based agency rates for equivalent seniority.

• Small ($13,000–$30,000): MVP scope with one to two core screens, a REST API integration, and basic authentication. 80–200 hours. Suitable for validating a product concept before committing to a full build.
• Medium ($30,000–$90,000): Full cross-platform app with offline support, push notifications, and a backend or CMS. 200–600 hours. Typical for an internal tool or early-stage product launch.
• Large ($90,000–$180,000): Platform-grade app with multiple integrations, admin tooling, and managed App Store and Play Store release cycles. 600–2,000 hours.

FCA or PRA-regulated scope adds 15–25% for audit trails, change management documentation, and compliance review cycles. We build that into the scoping document upfront. Full breakdown: React Native development cost guide.

How to start working with us

1. Discovery call (30 minutes): We talk through what you are building, your timeline, and any regulatory constraints. We want to know if this is a fit before either side commits time.
2. Scoping document: We write a fixed-scope brief with milestones, team composition, and a price range. You can take it to other vendors for comparison.
3. Project start: Once the scoping document is agreed, we assign the team, set up your shared channel, and begin sprint one.

Do you work with London companies remotely?

Yes. We work with UK clients entirely remotely. London is GMT in winter and BST (GMT+1) in summer; our team is IST (GMT+5:30). That produces 3.5 to 4.5 hours of real-time overlap in London's morning each working day. We communicate over Slack or Microsoft Teams, run code review on GitHub, and track sprint work in shared boards.

On data obligations: we can sign a Data Processing Agreement as a data processor under UK GDPR. For FCA-regulated clients, we operate within change management and audit trail requirements from project kickoff. Data residency questions, where data lives at rest, are addressed in scoping. The standard answer for UK clients is Azure UK South or UK West regions. The ICO (Information Commissioner's Office) and the FCA both publish clear guidance on app data handling that informs how we structure data handling agreements with London clients.
