Mergers and Acquisitions process | How to efficiently do Acquisitions in simple steps in 2025
A practical, step‑by‑step guide to executing acquisitions in England & Wales in 2025. Covers the acquisition lifecycle, core legal and regulatory risks, deal documentation choices and a concise practical checklist for in‑market and cross‑border transactions.

Our London office (Holborn Gate, 330 High Holborn, London, WC1V 7QH, England) acts for strategic and financial buyers and sellers on domestic and cross‑border transactions. This note summarises a practical approach to acquisitions under England & Wales law in 2025 and highlights the principal legal, regulatory and commercial issues to manage efficiently.
Acquisition lifecycle — a high‑level roadmap
An efficient acquisition follows disciplined stages that reduce execution risk and transaction cost. Typical stages are:
- Strategy and target identification (fit, synergies, high‑level valuation).
- Initial approach, confidentiality agreement (NDA) and exclusive negotiation period.
- Due diligence scope and resourcing (legal, tax, commercial, financial, regulatory, IT and data protection).
- Deal structure selection (asset purchase, share purchase, merger; financing and tax considerations).
- Document drafting and negotiation (heads of terms, sale and purchase agreement, ancillary documents).
- Pre‑completion conditions and regulatory clearances.
- Completion mechanics, funds flow and post‑completion integration.
Key legal and regulatory considerations in England & Wales
Prioritise the following matters early: merger control (Competition and Markets Authority thresholds), sectoral regulation (financial services, aviation, defence, utilities), employment issues including TUPE where staff transfer, tax implications (stamp duty, indirect tax and corporate tax), competition/antitrust compliance, sanctions and anti‑money‑laundering checks and data protection/IT resilience. Certain elements (for example land law and security enforcement) differ in Scotland and require separate consideration if Scottish targets or assets are involved.
Practical acquisition checklist
- Define commercial objectives and deal levers (price, timing, warranties, completion mechanism).
- Agree an NDA and short heads of terms to crystallise key commercial points and exclusivity periods.
- Prepare a targeted due diligence plan and allocate internal and external resource with timelines.
- Decide structure: share sale vs asset sale vs merger; assess tax, regulatory and contractual consent impacts.
- Negotiate key deal points: price mechanism (locked‑box v completion accounts), warranties, indemnities, caps, escrows, and earn‑outs if applicable.
- Assess the need for W&I insurance and the implications for disclosure and timing.
- Plan regulatory filings early (CMA pre‑notification where appropriate) and prepare employee communications and consultation plans.
- Agree completion timetable, funds exchange, and post‑completion integration milestones (governance, systems, contracts).
Documentation, risk allocation and practical protections
The sale and purchase agreement is the centrepiece for allocating risk. Typical protections include seller warranties and disclosure schedules, indemnities for known liabilities, conditionality for consents and approvals, escrow arrangements to secure post‑completion claims and completion accounts or locked‑box price mechanisms to govern adjustment risk. For cross‑border deals, factor in governing law, dispute resolution and enforceability of remedies.
