How much does bespoke software cost in the UK?
Bespoke software in the UK typically ranges from £25,000 for a lean first release to £150,000+ for a complex multi-tenant platform. The price is driven by integrations, business logic and non-functional requirements like security and scale — not the number of screens. A good build is priced by outcome, and a lean first release that proves value is almost always the smarter place to start.
There’s no honest flat number, but there are honest ranges. For custom software in the UK in 2026:
- Lean first release (MVP): £25,000–£60,000
- Standard business system: £60,000–£150,000
- Complex platform / SaaS: £150,000+
The cost is driven less by how it looks and more by what it does — the integrations it touches, the business rules it enforces, and the security, uptime and compliance behind it.
The biggest saving isn’t a cheaper team; it’s scoping the right first release so you invest once the value is proven, not before.
