What Insurance Do You Need for Your Mobile App Business?

One minute you're celebrating your app's launch and the next you're staring at a legal letter claiming your platform accidentally leaked user data or that a bug in your code cost a client tens of thousands in lost revenue. I've watched brilliant developers get blindsided by insurance gaps they didn't know existed, and honestly it's one of those things that nobody really thinks about until something goes wrong... which is exactly when it's too late to sort out proper cover.

Most app developers I speak with assume their general business insurance covers everything they do, only to discover massive gaps when they actually need to make a claim.

After building apps for healthcare providers, financial services firms and retail businesses over the past decade, I've learned that insurance for app development work isn't the same as cover for a traditional business. The risks are different, the claims can be eye-wateringly expensive (we're talking six figures sometimes), and working out what you actually need can feel like reading a foreign language. Look, I'm not an insurance broker but I've been through this process probably thirty times now for various projects and clients, and I can tell you what matters based on real situations we've faced.

Understanding the Basics of App Business Insurance

The thing is, app development sits in this weird space between software development, product creation and professional services... which means you need a mix of different insurance types that traditional businesses might not bother with. When you're writing code that handles someone's medical records or processes payments worth thousands daily, you're taking on serious responsibility whether you realise it or not.

Most app businesses need at least three core types of cover. Some need more.

Your insurance needs will change based on what kind of apps you build, who your clients are, whether you have employees and how you handle user data. An agency building simple brochure apps for local shops faces completely different risks compared to someone developing a fintech platform that processes transactions, and your insurance should reflect that reality. If you're working on health and fitness apps or medical applications, the liability concerns become even more significant.

• Professional Indemnity - covers claims about the work you deliver
• Public Liability - protects against third-party injury or property damage claims
• Cyber Insurance - covers data breaches and security incidents
• Employer's Liability - legally required if you have staff
• Product Liability - covers issues with your app after it's released

Professional Indemnity Insurance for Developers

This is the big one for app developers, and honestly it's probably saved my business at least twice. Professional Indemnity Insurance covers you when a client claims that your work caused them financial loss, whether that's because of mistakes in your code, missed deadlines, incorrect advice or design flaws that affected their business.

What Gets Covered

I worked on an e-commerce app where a payment gateway integration bug meant transactions weren't processing properly for about six hours before the client noticed. They lost around £15,000 in sales during that window and wanted compensation. Without Professional Indemnity cover, that would have come straight out of our pocket along with legal costs to defend ourselves... and legal fees add up frighteningly fast even when you haven't done anything wrong.

The policy typically covers your legal defence costs, any compensation you're found liable for, and sometimes even the cost of fixing the mistake itself. Coverage limits usually range from £100,000 to several million depending on your clients and project sizes. We carry £2 million cover because some of our contracts require it as a minimum. When hiring an application development agency, many businesses will specifically ask about Professional Indemnity coverage levels before signing contracts.

Always check your Professional Indemnity policy covers "loss of data" as a separate item, not just errors in your work, because data issues are increasingly common claim triggers and some policies try to exclude them.

Common Gaps People Miss

Many policies won't cover you if you guarantee specific results like "this app will increase your sales by 50%" or promise uptime percentages without proper infrastructure behind them. They also often exclude work you do outside your normal scope, so if you suddenly take on blockchain development when you usually build standard mobile apps, you might not be covered for that project. This is why it's crucial to have proper backup and deployment processes in place as part of your risk management strategy.

Public Liability Coverage Explained

Public Liability feels less relevant for app developers since we mostly work behind computers rather than on client sites, but you'd be surprised how often it matters. This covers injury to third parties or damage to their property caused by your business operations.

Here's a real example from our experience... we were meeting a client at their office to demo an app build, I tripped over my own laptop bag in their reception area while setting up, and knocked over an expensive architectural model they had on display. It shattered. Public Liability covered the £3,200 replacement cost and saved what would have been an incredibly awkward conversation about whose personal money was paying for it.

If you ever visit client premises, attend conferences, rent office space or have clients visit your workspace, you need this cover. It's usually quite cheap, often around £100-200 annually for basic coverage of £1-2 million, which makes it a no-brainer really.

Cyber Insurance and Data Protection

This has become non-negotiable over the past few years, particularly since GDPR came into force. Cyber Insurance covers you when there's a data breach, cyber attack, or security incident involving information you hold or process. For app developers who handle user data, payment information or health records, this isn't optional anymore. The Apple App Store hack we saw a few years ago demonstrated just how vulnerable even major platforms can be to security threats.

The average cost of a data breach for a small business runs between £25,000 and £50,000 when you factor in notification costs, legal fees, regulatory fines and remediation work.

I know a development studio that had their AWS credentials compromised, someone spun up about £8,000 worth of instances for crypto mining before they caught it, and hackers had accessed a database containing email addresses for about 3,000 users. The technical fix was maybe £2,000, but notifying users, hiring a security consultant to investigate properly, legal advice on GDPR obligations and dealing with the ICO inquiry cost them another twenty grand on top.

What Cyber Policies Actually Cover

Good Cyber Insurance policies cover breach notification costs, legal defence against regulatory action, public relations help to manage the fallout, forensic investigation to work out what happened, and sometimes even cyber extortion if you're hit with ransomware. Some policies also cover business interruption if an attack shuts down your operations.

The tricky bit is that policies vary wildly in what they exclude. Some won't cover you if you haven't implemented basic security measures like two-factor authentication on critical systems, regular backups or encrypted data storage. They'll ask detailed questions about your security practices before giving you cover, and they're not just ticking boxes... they'll actually check if you make a claim. Understanding app development statistics around security incidents can help you appreciate why insurers are so thorough with their assessments.

Employer's Liability and Team Coverage

If you employ anyone, even part-time staff or contractors in some cases, you legally need Employer's Liability Insurance in the UK. It covers claims from employees who get injured or become ill because of their work with you. The legal minimum coverage is £5 million and you can be fined £2,500 for every day you're not properly insured.

For app developers this might seem unnecessary since we're not exactly operating dangerous machinery, but repetitive strain injuries, stress-related illness and problems from poor workplace setup are surprisingly common claims. Realistically, most of us spend eight to ten hours daily at computers, and that takes a toll over time. Implementing productivity hacks to streamline app development can actually help reduce some of these workplace health risks by making work processes more efficient.

Who Counts as an Employee

This gets complicated quickly. Permanent staff definitely count. Contractors might count depending on how much control you have over their work. Freelancers you bring in for specific projects usually don't count if they're genuinely self-employed with their own insurance, but the line gets blurry if you're directing their day-to-day work like you would an employee.

• Full-time and part-time permanent staff always need cover
• Apprentices and trainees count as employees
• Temporary workers might be covered by the agency supplying them
• Contractors may need cover depending on IR35 status and working arrangements
• Volunteers need cover in some situations even though they're unpaid

To be honest, if you're unsure whether someone needs to be covered, ask your insurer directly with specific details about the working arrangement. Getting this wrong can invalidate your entire policy.

Product Liability for Mobile Applications

Product Liability covers claims arising from products you create and sell or distribute, which for app developers means the apps themselves. This becomes relevant when your app causes harm to users or third parties after it's been released, particularly if you're selling apps directly rather than just building them for clients.

The most obvious cases involve apps that give medical advice, handle financial transactions or control physical devices. I worked briefly on a consultation for a health and fitness app that was giving exercise recommendations... the startup behind it nearly got sued when someone claimed they injured themselves following the app's workout plan. Product Liability would have covered that defence. This is why proper app idea validation should include risk assessment for potential liability issues.

When This Cover Matters Most

If you're building apps under contract for clients, your contract should specify who holds Product Liability, but don't just assume it's the client. Some contracts try to push all liability back onto the developer regardless of how the client uses or modifies the app later. I've seen contracts where the developer remained liable even for bugs introduced by the client's own team after handover, which is completely unreasonable.

Get your solicitor to review client contracts specifically for liability clauses before signing, because standard insurance policies won't cover liability you've contractually accepted that goes beyond normal negligence.

How Much Does App Business Insurance Actually Cost

Right, let's talk actual numbers because this is probably what you're most curious about. Insurance costs vary massively based on your revenue, the type of work you do, your claims history and how many people you employ... but I can give you realistic ballpark figures from our experience and what I've seen other agencies paying.

For a solo app developer or very small agency turning over maybe £50k-100k annually, you're probably looking at around £600-1,200 per year for a basic package covering Professional Indemnity and Public Liability. That usually gets you about £250k-500k Professional Indemnity cover and £1-2 million Public Liability cover, which honestly isn't enough if you're working with serious clients but it's a starting point.

Once you're turning over £250k-500k and working on bigger projects, expect to pay somewhere between £1,500 and £3,000 annually. We currently pay about £2,400 for £2 million Professional Indemnity, £2 million Public Liability and basic Cyber cover up to £100k. That covers our team of four developers plus freelancers we bring in regularly. When you're working on branding-focused mobile applications, clients often expect higher coverage levels as these projects typically have greater commercial impact.

What Pushes Costs Up

Working in high-risk sectors like healthcare, finance or anything involving children will increase premiums significantly, sometimes doubling them. If you've had previous claims, expect to pay more. Higher coverage limits cost more obviously, but the jump from £1 million to £2 million cover isn't usually double the price, more like 40-60% more.

Cyber Insurance pricing has gone up quite a bit recently, probably 30-50% over the past few years as insurers have seen more claims. You'll pay more if you handle lots of personal data, payment information or work with particularly sensitive information. Our Cyber cover costs about £400 annually as part of our package.

Employer's Liability is relatively cheap, usually working out to maybe £100-300 per employee annually depending on their role and your industry. Public Liability is almost always the cheapest part of your insurance package unless you're doing something unusually risky.

Conclusion

Look, insurance for your app business isn't exciting and it feels like money disappearing into a hole until the day you actually need it... then it suddenly becomes the best investment you ever made. I've had conversations with developers who thought they could skip proper cover until they were bigger or more established, and almost every single one eventually regretted taking that risk.

The baseline for most app development businesses should be Professional Indemnity and Public Liability as a minimum, with Cyber Insurance added pretty much immediately if you're handling any user data beyond basic contact details. If you have employees, Employer's Liability isn't optional. Product Liability depends on what you're building and who owns the final product.

Start with getting quotes that actually match what you do rather than generic tech business cover, ask specific questions about gaps and exclusions, and don't just go with the cheapest option because insurance policies can vary wildly in what they'll actually pay out for when something goes wrong.
