A Telegram Mini App costs £3,500 to £10,000 from a UK studio in 2026 and takes four to ten weeks to build. A Telegram bot, which covers a surprising share of the same jobs, runs £1,500 to £5,000 and ships in two to six weeks.
Larger builds exist: agency guides put advanced apps with heavy backends at $25,000 to $55,000. Most businesses don’t need one. This guide covers what a Mini App is, what the money buys, and how to tell whether you need the £4,000 version, the £1,500 bot, or neither.
What a Mini App is, and why businesses build them
A Mini App is a full web application that opens inside Telegram: a shop, a booking screen, a game, a dashboard. No app store, no download, no separate login. The user taps a button in a chat and the product is running, with their Telegram identity already attached.
The reach explains the interest. Telegram passed 1 billion monthly users in 2025, and Mini Apps alone count around 500 million monthly users across 55,000 active apps in 2026. For a business whose customers already live in Telegram chats, a Mini App removes the hardest step in mobile: convincing someone to install anything.
One number to weigh before you budget: of those 55,000 apps, fewer than 2,000 earn meaningful revenue. The winners are built for a specific audience with a specific job, a shop for an existing channel, a booking tool for a real service, a game with a plan behind it. A Mini App built because Mini Apps are trending joins the other 53,000.
What the money buys
These are the guide prices we quote at ICE WIND:
| Project | Typical price | Typical delivery |
|---|---|---|
| Telegram bot | £1,500 – £5,000 | 2–6 weeks |
| Telegram Mini App | £3,500 – £10,000 | 4–10 weeks |
| Payments (Stars, Stripe or another flow) | £750 – £2,000 | added to the build |
| Ongoing support and improvements | £900 – £1,750 / month | monthly retainer |
International guides bracket the same territory: EvaCodes puts an MVP at $2,000 to $8,000 and a standard app at $8,000 to $25,000, with Western European agencies billing $80 to $140 an hour.
The bottom of the range buys a focused app: one clear user journey, a light backend, Telegram login, delivered fast. The top of the range buys product infrastructure: accounts and roles, a database that survives growth, an admin panel so your team can change prices without calling a developer, and integrations with whatever already runs your business. At that point the job is web application development with Telegram as the front door.
What drives the price up
The backend decides most of the quote. A Mini App that displays a catalogue and takes orders through a simple flow sits near £3,500. Add stock levels that sync with your existing system, customer accounts with history, and staff roles with different permissions, and you are building a full web platform that happens to live inside Telegram. We cover that economics in our guide to website costs in the UK, and the same logic prices a Mini App.
Payments come second. Telegram handles digital goods through Stars, its in-app currency, while physical goods and services run through providers like Stripe. Wiring either in properly, with receipts, refunds and failure handling, adds £750 to £2,000. Budget it from the start if you plan to sell anything, because a checkout bolted on later costs more.
The admin panel is the cost people forget. The app your customers see is half the build. The other half is the screen where you add products, see orders and change prices. Skip it and every small change becomes a developer task at developer rates.
Games are their own economics: art, balance and retention loops on top of the engineering. We build Telegram games under our game development practice, and they range wider than business apps in both directions.
Bot or Mini App?
A bot is a conversation; a Mini App is a screen. If the job is answering questions, taking bookings through a short dialogue, sending notifications or qualifying leads, a £1,500 to £3,000 bot does it and ships weeks sooner. Bots also pair well with automation behind the scenes, the same builds we describe on our AI automation page, so a bot that reads documents or drafts replies is a natural first project.
You need the Mini App when the interface is the product: browsing a catalogue, picking seats, playing a game, anything where a chat window fights the user instead of helping. Plenty of our projects start as a bot, prove the demand, then grow a Mini App on top of the same backend. That order costs less than guessing.
Against a native mobile app the comparison is shorter. A comparable iOS and Android build starts around £15,000, needs app store review, and asks users to install it. If your audience is on Telegram, the Mini App gets you to the same screen for a quarter of the price. If your audience isn’t on Telegram, none of these numbers matter and you should spend the budget elsewhere. We will tell you which case you are in if you send a short brief through start a project.
