How to find off-market acquisition targets in the UK

Many of the businesses you would most like to own are not for sale. Their owners are busy running them. Some have half a mind on retirement, some have never thought about it. None of them are on a broker's list, so you will not find them by waiting.

Finding them follows a clear sequence: define what fits, research the whole market, prioritise, approach owners in confidence, then qualify and record what you learn. Each step depends on the one before it. Most searches that stall skipped the first.

Step 1: Define what you are looking for

Before you build a list, write down what you want to buy and why. That is your acquisition thesis. For a search, it needs to cover five things you can actually check from outside a business:

• Sector and activity. Be specific about what is in and what is out. "Fire and security" is a sector. "Fire alarm and emergency lighting maintenance for commercial buildings, not new-build installation" is a search.
• Size. A range for turnover, headcount or both. Use ranges, not a single number.
• Geography. The regions you want, and the ones you already cover or will not enter.
• Capability. What the business must bring: an accreditation, a customer base, a skill, a contract type.
• Ownership. Who you expect to be talking to: founder-owned, family-owned, an owner nearing retirement with no obvious successor. Most searches exclude businesses already owned by private equity or a larger group.

If a criterion cannot rule a business out, it is not doing its job.

Step 2: Research and prioritise the market

Off-market targets come from research. No single source is complete, so combine several.

The limits of public data

Filed information is a starting point, not an answer.

• Industry codes are self-selected. Companies choose their SIC (industry classification) code from a condensed list when they file (Companies House). Plenty of businesses pick a broad or out-of-date code, so a code-only search misses good fits and includes poor ones.
• Many accounts show no profit figures. A company meeting two of three tests (turnover of £15m or less, £7.5m or less on its balance sheet, 50 employees or fewer) can choose not to file its profit and loss account (GOV.UK). For many targets in the range our readers look at, you will not see turnover or profit until the owner shares it.
• Accounts are out of date. Private companies have nine months after their year end to file (GOV.UK), so the latest accounts can describe a business as it was well over a year ago.

That is why prioritising matters. Score each business against your criteria using everything you can see, then agree a shortlist before anyone is contacted. Here is what a single research record might look like.

Step 3: Approach owners in confidence

The first approach shapes everything after it. Our guide to approaching a business owner goes into detail, but the principles are simple:

• Make it personal. Write to the owner by name, about their business, not a template sent to hundreds.
• Be credible. Say who you are, or who you act for, and why their business specifically. Owners take an approach more seriously from someone who clearly understands their market.
• Respect confidentiality. Owners worry about staff, customers and competitors hearing they have been approached. Say plainly that the conversation is private and exploratory.
• Do not lead with price. The first conversation is about fit and what matters to them: their people, their customers, what happens next for the business they built.
• Follow up, politely. Owners are busy, so one letter is rarely enough. Follow up a small number of times, through a sensible mix of letter, email and phone, and stop when asked.

Expect most owners to say no or not now. That is normal. Record their answer and the reason, because circumstances change.

Step 4: Qualify and record what you learn

A long list of names is not a pipeline. Keep three groups separate:

1. Suitable companies. Businesses that fit your criteria on paper. You have not spoken to the owner yet.
2. Interested owners. Owners who have agreed to a confidential conversation. Interest is not the same as intent.
3. Real opportunities. Owners who have shared enough information, and shown enough willingness, that you can sensibly discuss value and terms. Our guide to qualifying an acquisition target covers the questions to ask.

Record everything in one place: who was approached, when, what they said, what you know and what you still need. It stops two people contacting the same owner, and it means a "not now" in 2026 can be picked up properly in 2028.

Is off-market always cheaper or less competitive?

No. Off-market means the business is not being marketed when you approach. It does not mean the owner will sell, or sell for less.

There is reasonable evidence that competition between buyers pushes prices up. A study of 1,592 private equity buyouts found entry prices rose with competition for deals, and higher entry prices were linked to weaker returns (Füss et al., 2025). But a study of US listed companies found sellers did about as well in one-to-one negotiations as in auctions (Boone & Mulherin, 2007). Neither was about owner-managed UK businesses.

In practice, an owner you approach directly will often take advice, and their adviser may contact other buyers. What an off-market approach does give you is time: to understand the business, build a relationship with the owner and make your case before a formal process starts. Plan to pay a fair price, and decide what the business is worth to you before you start negotiating.

How long does it take?

The research and first approaches can be done in weeks if someone is working on them full time. Conversations then move at the owners' pace, not yours. Some owners are ready within months; others need a year or more. Our guide to how long an acquisition takes sets out what happens after the first conversation.

Should you do this yourself?

You can. Some owners run their own search with help from their finance director and a good database subscription. The practical limits are time, data and confidentiality: research and follow-up take steady hours each week, and an approach that names your company tells the market you are buying.

Getting help with the search

If you want the search done properly but cannot give it the hours, Acquisitiv Target 45 is built for exactly this. In 45 days we research 100 businesses that fit your criteria, agree the list with you, approach the owners in confidence and make five introductions to owners open to a confidential conversation about a sale. If we are short at day 45, we keep going at no extra fee. It does not promise a completed deal; it gives you real conversations with the right owners.
