Who this guide is for

For the owner of a heating, ventilation or air conditioning business who expects to sell in the next few years. It also shows a buyer where to look between the offer and completion.

What you will take from it

  • Quote the installation margin your job sheets show, with engineer hours on commissioning and snagging visits booked to each job.
  • Put a cost on every open callback, age every debt against its own terms and give each retention a release date before a buyer asks.
  • Raise the gaps that change the profit, the cash or the right to do gas and refrigerant work before the offer. It does not guarantee the price holds.

What is inside

  1. Why a price moves after yes
  2. Margins that do not reconcile
  3. Tickets that lapse or sit with one person
  4. Callbacks and warranty jobs
  5. Debts past their terms
  6. Retentions counted as cash
  7. The order you disclose in
  8. What the public record shows

The tool: early disclosure list

One page with a line for each weak spot a buyer can find in your records. Write the evidence you hold, when you will raise it and who owns it, and tick it once the buyer has seen it.

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