Who this guide is for
For anyone reading listings of heating, ventilation and air conditioning businesses for sale: a first-time buyer, a trade firm looking for a second business, or an investor. It also shows a seller which documents a buyer can ask for after reading the listing.
What you will take from it
- Split the turnover into installation, contract and reactive work before you compare two listings.
- The adjusted profit in the example listing adds the owner's pay back without taking off the cost of replacing the owner's work.
- Gas Safe registered and F-gas certified describe the company, so ask for every engineer's card to see who covers the work once the owner has gone.
