Power Apps Development Services for UK Organisations
Hammerhead Tech builds Microsoft Power Apps that replace the spreadsheets, paper forms, email chains and Access databases your teams depend on. Each app is designed around how the work actually happens, secured with proper roles, and built to be supported long after launch.
We build canvas apps for task-focused, mobile-friendly jobs, model-driven apps for case and records management on Dataverse, and a mix of both where it makes sense. Apps connect to Microsoft 365, SharePoint, Teams and your other systems.
As part of our wider Power Platform consultancy, we can add the automated workflows, reporting and external portals that most apps eventually need.
From Spreadsheet to Secure Business App
Many of the apps we build start life as an Excel tracker or an Access database that has outgrown one person’s laptop. Data gets duplicated, versions conflict and nobody can see the full picture. A Power App gives everyone one place to work, with the right permissions.
We start by mapping the process, the data and the people involved. From there we design a Dataverse data model, agree screens and rules with your users, and build in short iterations with regular demos, so feedback shapes the app before it’s finished.
Before go-live we migrate your existing data, test with real users and set up separate development, test and production environments. Your team gets training and documentation, and the app is packaged in a solution so future changes can be deployed safely.
Types of Power Apps We Build
The right type of app depends on who uses it, where they use it and how much data it handles. We recommend an approach during discovery, and many solutions combine more than one.
Model-Driven Apps
Built on Dataverse for structured, data-heavy work: case management, referrals, complaints, CRM-style records and asset registers. Forms, views, business rules and security roles are configured rather than hand-built, so they’re robust and easy to extend.
Canvas Apps
Apps designed screen by screen for specific tasks such as inspections, site visits, timesheets and stock checks. They work well on phones and tablets, can capture photos and signatures, and connect to Dataverse, SharePoint or SQL.
Apps in Microsoft Teams
For teams that live in Microsoft Teams, we build apps that sit alongside chats and channels, so requests, approvals and updates happen where people already work. Lighter use cases can run on Dataverse for Teams without extra licences.
Power Apps for Public Sector, Care and Growing Businesses
Much of our Power Apps work is for organisations where records are sensitive and processes are regulated. We’ve built case management on Dataverse for fostering and children’s services, where audit history, role-based access and clear reporting are essential.
For councils and housing providers, Power Apps can digitise inspections, referrals and service requests using licences many already hold through Microsoft 365. For property firms and growing businesses, apps replace manual trackers for jobs, assets, compliance and onboarding.
If a requirement goes beyond what low-code does well, such as a high-volume public app or complex custom logic, we also offer bespoke software development and can combine the two. For customer and case records, see our CRM and case management services.
Why Choose Hammerhead Tech for Power Apps?
Power Apps is easy to start and easy to get wrong. Apps built without a data model or security design tend to slow down, break when a key person leaves, and fail governance reviews.
We build apps as properly engineered solutions, following Microsoft’s recommended practices for environments, solutions and application lifecycle management, so they stay fast, secure and maintainable.
Data Model First
We design Dataverse tables, relationships and security roles before building screens, so the app performs well and reporting in Power BI is straightforward.
Real Users Involved Early
Short build cycles with regular demos mean your staff test the app as it takes shape, while changes are still quick and cheap to make.
Integrations That Hold Up
We connect apps to Outlook, SharePoint, finance and line-of-business systems using standard or custom connectors and Power Automate, with error handling and logging.
Clear Licensing Advice
We’ll explain whether your users need per-app or per-user licences, or whether your Microsoft 365 rights are enough, before you commit to a build.
Handover or Ongoing Support
You get documentation and training at handover. We can also support the app after launch, monitor it and keep improving it as your needs change.
Frequently Asked Questions
What is Power Apps used for?
Power Apps is used to build business applications without writing a full custom codebase. Common uses include case management, inspections, requests and approvals, asset tracking, HR processes and replacing systems built in Excel or Access.
What's the difference between canvas and model-driven apps?
Canvas apps give full control over layout and suit task-based or mobile use. Model-driven apps are generated from a Dataverse data model and suit complex, record-based processes. Many solutions use both.
Can Power Apps replace our Access database?
Usually, yes. We move the tables to Dataverse or SQL, rebuild the forms and reports in Power Apps and Power BI, and keep your business rules. Users get a secure, multi-user app that works in a browser and on mobile.
Do our staff need new licences?
Apps that use standard connectors such as SharePoint can often run under existing Microsoft 365 licences. Apps that use Dataverse or premium connectors need Power Apps licences. We’ll confirm the options for your users during discovery.
How long does a Power Apps project take?
A focused app can often be live within a few weeks. Larger, multi-team systems are usually delivered in phases, with a first release followed by further features once people are using it.
Can you improve an app someone else built?
Yes. We review existing apps for performance, security and maintainability, fix issues, and move them into proper environments and solutions so they can be supported.
Will the app work on phones and tablets?
Yes. Power Apps run in the Power Apps mobile app on iOS and Android and in web browsers. Canvas apps can also be designed to work offline for field teams, syncing when a connection returns.
