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
- How many owners are 60 or over
- Buying tickets that leave with the owner
- Calling repeat work recurring income
- Paying for the owner's job twice
- Treating the invoice book as cash
- Counting engineers instead of capability
- Missing old installation promises
- Guessing the refrigerant problem
- Buying yesterday's new-build mix
- 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.
