If you’re looking for a UK app developer then you’ve definitely come to the right place. The UK has been referred to as a “powerhouse” of the global app development market and the data strongly backs that up.

In 2016, 91% of people in the 18-44 age bracket owned a smartphone – that’s a total of 21 million phones for that range alone. Statista estimates there are a total of 42.4 million smartphone users in the United Kingdom.

The app development market naturally follows, with plenty of app developers both in London and beyond, another hub being Manchester. This guide looks at the UK app development scene in detail, counting up the cost of having a mobile application developed in the country. It won’t go cover freelancers but it does go over what you should think about when choosing a UK-based app developer and then list some of the best companies who operate here.

This guide is divided into four sections:

We begin with an overview of the app developer market in the UK.

The app developer market in the UK

It’s a strong one.

Revenues in the UK app developer market are forecast to be more than £31 billion by 2025, and according to a report by Vision Mobile, the economy will be worth more than £30 billion by 2030.

App developers can be found all over the United Kingdom, but the majority is clustered around London. Of its 8000 app-development-related companies (around a fifth of all European app development agencies), 31% are located in the capital, and about 25% of those in the south-east part of the city.

It’s estimated that these together employ 380,000 people (though not all of them are developers – this includes designers, admin and marketing people involved in the app industry.)

With all signs that the industry is growing, what kind of prices can you expect to develop a mobile application in the UK?

UK app development costs

How do UK app development costs measure up globally?

Globally, average prices for developing an iOS mobile app are approximately (in US Dollars) $27,000, $23,000 for Android and $18,000 for Windows phone.

The UK has some of the best app developers in the world, and thus costs can be close to the global average. According to Waracle, a Scottish developer, said in 2014 a single platform app could cost anywhere between £8000 and £13,000 and more, while a three-platform app can reach £50,000. Costs have only increased with demand since then.

The amount a developer charges per hour also comes close to global highs. Below you can find a graph for the estimated minimum and maximum you can expect to pay hourly for an app developer to work on your iOS or Android app.

The reason for the high price is quality: not only are some of the best app developers in the world found here, but many US firms have offices here – while not technically from the UK, they operate on the territory and raise the average.

Having had a glimpse of the cost and skill of the developers in the UK, how do you go about choosing one?

How to choose app developers in the UK

There’s a few things you should know:

Two major sections: the research you can do on your own, and the interview phase with the app developer, where you’ll explore their skills and expertise while they try to understand your business and your app. The research you can do at home is as follows:

  • Review their portfolio: not only to see how many apps they’ve made and how successful they’ve been, but also to see which industries they’ve worked for. A niche social network app has vastly different characteristics and challenges to a mobile enterprise app for industry. Experience in your specific field of business is just as important as development skills.
  • Recommendations: ask others in your industry who have launched successful apps to recommend a developer, or find out who made the most successful apps if there’s an industry benchmark.
  • Check out our Market Place: You’ll find a wealth of information and app developer profiles in Business of App’s Marketplace.

The more you know of your app developer, the better questions you can ask

What questions should you ask?

So what does this entail?

This is an exploration phase, and it goes both ways. You’ll be trying to find out what it’s like working with the app developer, what their approach is, where they excel and what their philosophy on design is. On the other hand, the app developer will want to know what it’s like working with you, your expectations, your business model for the app and how you plan to take it forward and expand it. It’s a conversation, and an enjoyable one at that – both parties are thinking about how to do business together, and both have a vested interest in the success of the app. So what should you look to ask?

1. What platforms do you develop for natively? Do you develop cross-platform apps?

You want to know this right from the start, especially if you have a specific platform in mind or if you want to be platform-agnostic. The difference between iOS, Android and cross-platform can be monumental, so it’s important you know which one you want to aim for. Coding natively for both iOS and Android can equal paying for two separate apps.

2. Do you cover every stage in the development cycle?

Some specialise in UX/UI, others in back-end, others still in integration. If your chosen company only does certain stages, then you’ll need to make sure whoever does the other parts can work well with them.

3. How can my app make money?

This is really something that you need to think of together, especially if your app is linked to your business. It is not uncommon for app development companies to also offer business plans and strategy advice as part of their services.

4. How do you communicate during the development process?

Are you the type to want constant updates, or would you rather sign off and only see the end product? Companies work in different ways and use different development processes, so you want to find one that suits your communication needs. There are app developers who communicate daily, while others only on major, significant updates.

5. What kind of testing will you do?

The polishing of an app is in the testing: from stress (basically overloading the app with activity to see how it behaves) to A/B, testing is key to making sure your app is successful and functional from the start.

6. Is submission to app stores included?

Submission to iTunes requires subscription and that the app adhere to strict guidelines. Android has fewer rules, but also requires a registration, and both ask for a publishing fee. There’s more to it than just submission as well: app store optimization can be the cherry on the cake of a well-thought out and slick marketing campaign.

7. What’s the latest tech you’re using?

This will get the conversation going, and perhaps there is some new technology your developers are using which could catapult your app to success.

8. What other app related services do you offer?

Many companies also offer strategic guidance, marketing campaigns, app store optimization, post-launch maintenance, branding advice and all the other activities that go behind a successful app. The world’s best app won’t go very far if no one knows it exists, or if it has an awful name.

Hopefully asking all these questions will give you a clearer idea whether the app developers in front of you are the right people to deliver your product, but also someone you’ll get along with. This is key, as your relationship with an app developer will rarely end upon publishing the app: there’s updating and maintenance to be done most of the time, and perhaps another app to be made if the first one is successful.

Having given you the rundown of what you can do, here are some of our reccomendations.
