Ask what it costs to add alerts to your app and you will usually get a shrug, because the cost to add push notifications is really two separate numbers that get blurred together. There is the one-off development work to build the feature, which for a typical app runs from roughly £1,500 for a basic setup to £12,000 for targeted, automated messaging. And there is the delivery service that sends the messages, which for most apps is free until you reach real scale. Confuse the two and you will either overbudget the build or forget to plan for the running cost once your audience grows. This guide separates them cleanly and shows what drives each one.
How much does the cost to add push notifications actually come to?
The cost to add push notifications is a one-off development cost plus, sometimes, an ongoing service fee. For most apps the build lands between £1,500 and £12,000 depending on how clever the messaging needs to be, while the underlying delivery infrastructure from Apple and Google is free. Managed services only start charging once you send to very large audiences or want advanced targeting and analytics.
That two-part shape is the whole answer in miniature. The build is what you pay a developer once to wire notifications into your product properly. The service fee, when it exists, is what a provider charges to handle delivery, segmentation, and reporting at scale. Founders who only budget for the first are fine at launch and surprised later, and founders who assume notifications are a quick afternoon job underestimate the engineering the first time they try to send the right message to the right person at the right moment.
Part one: the development cost
The development cost is the engineering time to connect your app to the notification systems, ask users for permission, store the device tokens that identify each phone, and send messages that actually arrive. A basic setup, where you can send a simple message to everyone who has the app, is the cheapest, because the flow is short and the logic is thin. That work usually lands between £1,500 and £4,000 for a typical build, assuming the rest of the app already exists.
Costs climb as the messaging gets smarter. Sending different messages to different user segments, scheduling campaigns, triggering a notification when someone does something specific, deep-linking a tap straight to the right screen, and reporting on who opened what all add engineering. A targeted, automated notification system commonly runs £6,000 to £12,000, because each of those behaviours is a feature in its own right that has to be built, tested, and made reliable. These ranges reflect what a studio charges for the notifications slice specifically, and they sit inside the wider picture we cover in how much an app costs to build in the UK in 2026.
Part two: the delivery service
Separate from the build, something has to physically deliver each message to each phone. On iOS that job is done by Apple Push Notification service, and on Android by Firebase Cloud Messaging. Both are provided by the platform owners and both are free to use, with no per-message charge no matter how many notifications you send. This surprises founders who assume messaging must cost money the way text messages do. It does not. The pipes are free.
Where cost can appear is the layer many teams add on top. Managed providers such as Firebase, OneSignal, and similar tools wrap those free pipes in a friendlier dashboard, audience segmentation, scheduling, A B testing, and analytics. Most of them have a generous free tier that covers small and medium apps completely, then charge once you cross a threshold of subscribers or want premium features. Because those thresholds and prices move, confirm the current numbers on each provider’s own pricing page before you commit, rather than trusting a figure in a blog post that will age.
What drives the cost to add push notifications up
Three things move the build cost more than anything else. The first is targeting. Sending one message to everyone is simple; deciding who should receive which message, and building the segments and rules behind that, is where the hours go. A notification that reaches every user is cheap to build and easy to get wrong, because irrelevant alerts are the fastest way to make people turn them off or delete the app.
The second driver is automation. A notification a human sends by hand from a dashboard is one thing. A notification the system sends automatically because a user abandoned a basket, hit a milestone, or went quiet for a week is another, because now you are building triggers, timing logic, and the rules that stop someone being bombarded. The third is everything around the message: deep links that open the right screen, permission prompts timed so people actually say yes, handling users who opt out, and reporting that tells you whether any of it worked. None of that is exotic, but each piece is real work, and together they explain why two notification features can differ by £10,000.
A worked example: a habit-tracking app
Picture an app that helps people build a daily habit and wants to nudge them at the right moment. At the simple end, it sends one reminder to everyone at 8am. That is a basic setup: wire in the platform services, ask permission, store tokens, send on a schedule. Built properly that lands near the bottom of the range, around £1,500 to £4,000, and the delivery itself costs nothing because Apple and Google carry the messages for free.
Now make it useful. The app should remind each person at the time they usually complete their habit, go quiet when they are on a streak, send an encouraging nudge if they miss two days, and never message someone who has turned reminders off. That is targeted, automated messaging, and it lands in the £6,000 to £12,000 range, because almost every one of those behaviours is a feature that has to be built and tested. The delivery is still free at this size, but if the app grows into hundreds of thousands of active users, a managed provider’s paid tier may enter the budget. A realistic plan names both: the build you pay once, and the service cost that may appear at scale.
Does iOS or Android change the cost?
Both platforms carry your messages for free, so the delivery side is even, but the build side is not always identical. If your app is native, meaning a separate iOS version and a separate Android version, then push notifications have to be wired into each one, and that can add engineering compared with a single shared codebase. A cross-platform app built once for both stores usually shares most of the notification logic, which keeps the cost closer to a single figure rather than two.
The other platform difference is behaviour rather than price. iOS asks users to opt in before an app can send anything, so how and when you request permission has a real effect on how many people you can actually reach, which in turn changes how much value the feature returns for what you spent. Android has historically been more permissive, though recent versions ask too. None of this changes the headline range much, but it is why we always look at your platform choice, covered in native versus hybrid versus PWA, before quoting a notification build. The cost to add push notifications is shaped as much by how your app is built as by how clever the messaging is.
Can you add push notifications cheaply yourself?
For the simplest cases, sometimes yes, and it is worth knowing when. If you just want to broadcast the occasional announcement to everyone, a managed tool’s free tier plus a modest integration can get you sending for very little, and for an early app testing whether notifications even move the numbers, that is the right move before you invest more.
The build cost reappears the moment notifications have to be smart rather than broadcast. Once you need the right message going to the right segment at the right time, triggered automatically by what people do, opening the right screen when tapped, and reported on so you can improve, you are building software, not clicking send in a dashboard. That is real engineering, and it is where the upper end of the range comes from. The honest rule of thumb is simple: use a free tier to prove notifications earn their place, then budget the proper build once they have. This is the same logic we apply to the platform decision in native versus hybrid versus PWA, because how your app is built affects how notifications behave.
What to do next
The cost to add push notifications comes down to two honest numbers: a one-off build of roughly £1,500 to £12,000 depending on whether you need simple broadcasts or targeted automation, and a delivery service that is usually free until you reach real scale. Budget for the build, treat the sending infrastructure as free at first, and add a managed provider’s paid tier to your model only when your audience is large enough to need it.
If you want a straight answer on what a notification feature would cost for your specific app, including where a simple broadcast is plenty and full automation would be overkill, send us a project brief and we will scope it honestly. And if you are weighing up other features at the same time, our breakdown of the cost to add Stripe payments to a UK app uses the same two-part method so you can budget the whole thing realistically.
