Who this guide is for

For anyone thinking of buying a heating, ventilation or air conditioning business: a first-time buyer, a trade firm adding a second business, or an investor. It also shows a seller what a careful buyer will ask for.

What you will take from it

  • Check that the certificates, the engineers' tickets and the customers stay with the business when the seller leaves.
  • Take the owner's job out of the profit before you value the business, and count only signed maintenance contracts as contracted income.
  • Score the eight checks on one page before you agree a price. One red matters more than several greens.

What is inside

  1. How many owners are 60 or over
  2. Buying tickets that leave with the owner
  3. Calling repeat work recurring income
  4. Paying for the owner's job twice
  5. Treating the invoice book as cash
  6. Counting engineers instead of capability
  7. Missing old installation promises
  8. Guessing the refrigerant problem
  9. Buying yesterday's new-build mix
  10. Four changes of ownership on the public record

The tool: buyer's red-flag scorecard

One page that turns the eight checks into a red, amber or green letter each. Type into the PDF and save it, or print it and take it to the meeting.

It comes as its own file as well as a page of the guide.
