How to build a repeatable buy-and-build strategy

"Buy-and-build" is usually described as something private equity funds do. It is the most common type of private equity deal in the UK: bolt-ons, meaning businesses bought to fit alongside an existing one, made up 59% of the 1,751 UK private equity deals in 2025 (KPMG, 2026).

But the approach does not belong to funds. A founder-led business with a strong core, a clear market and a little patience can run the same playbook, often with more flexibility, because there is no fund timetable forcing a sale. This guide covers how to make it repeatable rather than a series of one-off deals.

What is a buy-and-build programme?

There are two parts.

• The platform is your existing business: its management, systems, customers and brand. It is what everything else plugs into.
• The bolt-ons are smaller businesses you buy and bring together with the platform, each adding a region, a service, a customer group or capacity.

The difference from a single acquisition is that the programme is planned as a whole. You decide in advance what you want to add, in what order, at what price and how each business will be integrated. Every deal is judged against that plan, not just on whether it looks attractive on its own.

Before you start, check the platform is ready. If your own finance, operations and management are stretched today, they will break under three acquisitions. Our guide to growth through acquisition covers whether buying is the right route at all.

What should you add, and in what order?

Start with what you want to buy and why (your acquisition thesis), then break it into a sequence. The order matters because early deals should make later ones easier.

A first deal that is close to home teaches you how you integrate, without the extra risk of an unfamiliar market. Jumping straight to a new service line in a new region doubles the unknowns.

Be careful not to plan on the assumption that adding businesses automatically adds value. In BCG's study of private equity buy-and-builds, deals with one or two add-ons outperformed standalone deals, but those with more than two did worse than standalone deals on average (BCG, 2016). That is private equity data with a small sample, but the message is clear: more deals is not the same as more value. What an acquisition thesis is explains how to set criteria that hold.

How do you run a pipeline that keeps deals honest?

A repeatable programme needs the same stages, owners and stop rules every time. Without them, each deal is decided on enthusiasm.

Two rules make this work. First, write the stop criteria before you meet anyone. Second, make one person accountable for moving each deal through the stages. For how to judge a business against your criteria, see acquisition target qualification. For how to find businesses, including ones not for sale, see our guide to off-market acquisition targets.

Can you do several deals without disrupting the business?

This is the question that decides most programmes. Test three things.

Management bandwidth. Who runs the core business while you are negotiating, and who leads each integration? If the answer is "me" both times, the programme will stall. See how much management time an acquisition needs.

Funding. Map how each deal will be paid for: cash, bank debt, paying part of the price later if the business delivers, or outside investment. Check what your lender will support across the programme, not just for the first deal, and keep headroom so one disappointing year does not stop the next acquisition. Our guide to acquisition finance sets out the options.

Consistent operating processes. Decide what every acquired business will adopt (finance reporting, IT, health and safety, pricing) and what it can keep. In Bain's survey of 250 executives, more than 60% said they should have spent up to a third more time planning integration (Bain, 2005). PwC found that 79% of acquisitions where significant value was lost had no integration strategy at signing (PwC, 2019). A standard integration plan, reused and improved each time, is the single most useful asset a programme builds. Our post-acquisition integration guide covers the detail.

There is evidence that discipline pays. McKinsey found that large companies making more than two small or mid-sized deals a year outperformed their peers, while occasional acquirers on average lost ground (McKinsey, 2019). Those were large listed companies, so treat it as a principle, not a promise for a founder-led business.

An illustrative programme

This example is illustrative and fictional. A £15m IT managed services business in the Midlands decides to add three businesses over four years. The thesis: established managed services providers with £2m–£5m turnover, mostly recurring contract revenue, within two hours of head office, and no single customer above 20% of revenue.

Deal one is a smaller provider in a neighbouring county with a similar customer base. The team uses it to build its integration checklist. Deal two adds a cyber security capability. A third prospect reaches the price stage but the owner's expectations exceed the agreed walk-away figure, so the team stops and returns to the pipeline. That stop is the programme working, not failing.

Getting support for a continuous programme

A buy-and-build programme is never "done" between deals. The search, the pipeline and the integrations all need someone's attention month after month, which is hard for a founder who is also running the business. Some owners hire a corporate development lead; others outsource it. Our guide to in-house versus outsourced corporate development compares the two.

Keeping the programme moving

If you want a programme that keeps running while you run the business, the Acquisitiv Expansion Partnership acts as your acquisition team without the hire. We run your search, your pipeline and your live deals, coordinating your lawyers and accountants, and you keep every decision.
