Mobile App Development for UK Businesses
Most UK businesses searching for a mobile app development company need one senior developer who has shipped before — not an agency invoice with a London office inside it. I build iOS and Android apps in React Native, publish my GBP ranges openly, and work four hours ahead of you rather than half a world away.

GBP Pricing, Published
Converted from the USD bands used everywhere else on this site, so adjust a little for the day's exchange rate. The point is not the decimal place — it is that a number exists at all before you spend a week getting one.
| App type | GBP range | USD equivalent | Timeline |
|---|---|---|---|
| Validation MVP | £4,000 – £9,500 | $5,000 – $12,000 | 6–10 weeks |
| Standard business app | £9,500 – £19,500 | $12,000 – $25,000 | 10–16 weeks |
| Feature-heavy product | £19,500 – £47,000 | $25,000 – $60,000 | 4–6 months |
| Two separate native builds | ≈2× any row above | ≈2× | Nearly double |
Prefer monthly to a lump sum? App Development as a Service spreads the same work across a subscription. Apple's annual developer fee and Google's one-time registration are billed by them directly to your accounts.
What the UK Market Data Shows
I analysed 1,506 mobile app development keywords across 21 countries. The UK stood out for one reason: "hire react native developers" carries some of the highest advertiser bids in the entire dataset — around $35 per click — while sitting at a difficulty score of 5. Agencies are paying heavily for UK React Native leads rather than earning them. That tells you what a UK app lead is worth to the people competing for you.

"Offshore" usually means your questions get answered tomorrow. I work from Pakistan on UTC+5 — four hours ahead of UK summer time — so my afternoon is your morning. You raise something at 9am in London and it is being worked on before your second coffee. Decisions land the same day, which is the part that actually affects a timeline.
What You Get
- iOS and Android from one React Native codebase
- Both store submissions, under your own developer accounts
- The backend: auth, data, push notifications, payments
- Store listings built from real keyword research (I run an ASO tool)
- An honest answer when React Native is the wrong tool

Questions UK Founders Ask
How much does app development cost in the UK?
+
Working directly with me: roughly £4,000–£9,500 for a focused MVP over 6–10 weeks, £9,500–£19,500 for a standard business app, and £19,500–£47,000 for a feature-heavy product. These convert from the USD bands I publish everywhere on this site, so adjust slightly for the day's exchange rate. UK agencies quote multiples of this for the same scope.
Why is a UK agency so much more expensive?
+
Because the quote covers a London office, account managers, a sales team and the bench. None of those write your app. Hiring the senior developer directly removes every layer between the decision and the code — which is faster as well as cheaper.
What are the working hours like with a remote developer?
+
I work from Pakistan on UTC+5, four hours ahead of UK summer time. My afternoon is your morning, so calls and decisions happen inside your working day rather than at either end of it. In practice it feels closer to working with someone in continental Europe than offshore.
Do I get both an iOS and an Android app?
+
Yes — one React Native codebase produces both, sharing 85–90% of the code. That matters in the UK where iOS holds a large share but Android is far from negligible; building only one platform leaves real users out, and building two natively roughly doubles the bill.
Who owns the code and the App Store listings?
+
You do. The repository is yours and the apps publish under your own Apple and Google developer accounts — Apple's £/$99 annual fee and Google's one-time $25 are billed by them directly to you. Changing developer later costs you nothing but a handover.
How do contracts and payments work from the UK?
+
Scope and milestones agreed in writing before any payment, then bank transfer in GBP or USD. Nothing is held hostage: the code is yours from day one, so if the arrangement stops working you keep everything built so far.
Can you work with a UK startup that already has an app?
+
Yes, if it is React Native or Flutter. I read the codebase first and tell you honestly whether continuing beats rebuilding — and sometimes it does not. Knowing that in week one is worth more than any discount.
Tell Me About Your App
Send what it needs to do and who opens it. You will get back a realistic GBP scope, a timeline, and an honest opinion — including "don't build this yet" when that is the truth.
