Buying a business
Funding a buy-and-build: how roll-up acquisitions get financed
How a buy-and-build strategy is financed: the platform acquisition stack, a revolver for the bolt-ons, and what lenders want to see before deal two.
A buy-and-build strategy, sometimes called a roll-up, means buying one solid business as a platform, then adding smaller bolt-on acquisitions in the same sector. The finance follows that shape. A full acquisition stack buys the platform. Faster, lighter facilities fund each bolt-on. Here is how the pieces fit.
One note before the detail. This guide is about buying businesses, not building houses. If you searched for self-build property finance, you want a different page entirely.
Section 01
What a buy-and-build actually is
The sequence is simple to say and hard to do. Buy a platform. Bolt on smaller rivals or neighbours. Integrate them properly. Repeat.
The engine behind it is scale. Buyers tend to pay more per pound of profit for a larger, better-run group than for each small firm on its own. Build the group well and the whole becomes worth more than the sum of its parts. Integrate badly and the arithmetic runs the other way.
Section 02
Financing the platform deal
The first purchase is a normal acquisition, funded with the standard stack. Senior debt against the target's earnings, vendor support, and your own contribution.
The difference is what you set up alongside it. One structure from our own book paired a £4m term loan with a £1.5m revolving credit facility on an industrial acquisition. The term loan bought the business. The revolver stands ready for what comes next. That pairing is the classic roll-up shape.
Section 03
Financing each bolt-on
Bolt-ons are smaller, faster, and cheaper to fund than the platform was.
- The platform's own headroom. A well-run group generates cash and borrowing capacity for the next deal.
- A revolving facility drawn per deal. Agreed once, used many times, repaid from trading.
- The target's own assets. Stock, plant, and invoices in each bolt-on can fund part of its own price.
- Vendor deferral. Small sellers joining a bigger group often accept part of the price over time.
Some lenders will also agree the next facility in principle while the first is still young. That is worth negotiating on day one, when your leverage is best.
Section 04
What lenders want to see before deal two
The credit conversation changes after the first bolt-on. Now you are being assessed as an acquirer, not just an operator.
- One set of numbers. The platform and the first bolt-on reporting as a single group, cleanly.
- Savings that showed up. The overlaps you promised to remove, actually removed.
- Management bandwidth. Evidence the team can run what it already owns while diligencing the next deal.
The discipline matters more than the pace. The fastest way to kill a roll-up is buying the third business before the second is digested.
