The UK M&A Due Diligence Checklist

Big Four

PwC UK - due diligence services


Big Four Deals practice with global integrated FDD, tax DD and commercial DD capability. Anchors on regulated and large-cap deals.

Direct answer

PwC UK is a Big Four transaction-services firm. UK fees are quote-only: the firm publishes service descriptions, not rate cards. Engagement scopes are issued per workstream after a 5-10 working-day discovery window.


Workstreams covered

  • FDD
  • Tax DD
  • Commercial DD
  • Operational
  • M&A advisory

Sector focus

  • Financial services
  • Energy
  • Public sector
  • Industrials

Pricing approach

Quote-only. Fee premium over Tier-2 typically 1.5-2.5x at comparable scope. Worth it where multi-jurisdiction tax structuring or regulated-target compliance is on the critical path.

When to instruct

Big Four scope tends to be disproportionate at sub-£20m EV unless the target is regulated, multi-jurisdiction or carries unusual tax complexity. Insist on capped fees and a named partner whose hours appear on the engagement letter.
