If you're considering an acquisition in 2025, here's a practical breakdown of what you need to know before taking the next step.

Snapshot Summary

Buying a business can accelerate growth, but it comes with financial, legal, and operational risks. This article outlines what UK business owners need to know before acquiring in 2025, from building a clear business case to modelling costs, conducting due diligence, and avoiding common pitfalls.

 

Acquiring a business can be a powerful route to growth, whether you're looking to expand into new markets, strengthen your customer base, or secure new capabilities. But it’s not without risk. From hidden liabilities to working capital demands, what might look like a great deal on the surface can quickly unravel without the right approach.

Start with the right mindset

Before diving into numbers or negotiations, it’s important to get clear on your objectives and goals for doing it.

  • Why are you considering buying a business?
  • Are you after new customers or access to a specific market?
  • Is it about acquiring talent, IP, or infrastructure?
  • Are you trying to remove a competitor or create operational efficiencies?
Understanding your why will shape your strategy and stop you from getting distracted by the wrong opportunities.

Build a business case that holds up

Once you’ve got a clear strategic rationale, the next step is to create a business case. This should show how the acquisition will add value over time, and what assumptions you're basing that on.

Ask yourself:

  • What synergies or efficiencies can be unlocked?
  • What will success look like after 12–24 months?
  • Who in your business will be responsible for making the acquisition work?
The more realistic and grounded your case, the easier it will be to make sound decisions throughout the process.

Get the financial modelling right

Many deals come unstuck because the financials weren’t properly stress-tested. It’s essential to look beyond the headline price and understand the full impact on your business.

Here’s what to factor in:

  • Customer retention – Will all contracts transfer? What drop-off rate should you model?
  • Staffing – Will you inherit a team? Will you need to scale up your own resources?
  • Working capital – What will you need to keep things running day to day?
  • Payout terms – Is it a lump sum or staged payments? Are there performance-based earn-outs?
  • Stock – Will you be taking on inventory? If so, what is it worth, and will you need to replace it?
  • Capital investment – Are there systems, vehicles, or infrastructure you’ll need to upgrade or integrate?
Working closely with your advisors through each stage helps you stay on track and avoid missed details.

Are you aware of the common pitfalls?

Some of the biggest issues we see in acquisitions relate to what’s not in the sales brochure.

Here are some key areas to check:

  • TUPE & employee rights – Are there staff transferring over? If so, what are their terms and protections?
  • Stock – Is it usable? Does it match the value in the accounts?
  • Contracts – Can customer and supplier contracts be transferred or reassigned?
  • Undisclosed liabilities – Things like pending disputes, tax issues, or lease obligations.
  • Cultural fit – Will their ways of working mesh with yours?
Getting a full due diligence process in place (not just financial, but legal and operational too) is vital to protect your business.

Acquisitions can deliver transformational growth, but only if approached in the correct way, and with the right professional support.
