How much does technical due diligence cost in the UK?
UK technical due diligence typically runs from £8,000 for a focused, narrower-scope review up to £10,000+ for a full assessment covering architecture, code quality, security, technical debt, team capability, and infrastructure. Larger or more complex deals can run higher - every engagement starts with a scoping call to price it accurately.
What does a technical due diligence review actually check?
Architecture and how the system will hold up under growth, code quality and technical debt, security posture, infrastructure and deployment setup, and team capability. The report is written for both technical readers and the people making the investment decision.
How long does technical due diligence take?
A focused review typically takes one to two weeks. A full due diligence engagement, covering the complete technical and team assessment, usually takes two to three weeks depending on codebase size and complexity.
Do you offer technical due diligence for pre-seed or early-stage startups?
Yes. Early-stage due diligence is usually the Focused tier - a narrower, faster read rather than the full institutional-scale review a later-stage or larger deal needs. Book a scoping call and the right scope gets defined against the actual deal size.
