Questions to Ask Your Tradie

1. Are you F-Gas registered and will my logbook be updated?

2. Does the quote include electrics, condensate pump and VAT?

3. What noise levels (dB) and efficiency rating (A+++) will the chosen model achieve?

4. Will I need planning permission or freeholder consent for the outdoor unit?

5. How long is the parts-and-labour warranty, and who honours it?

6. What extra cost applies if you hit unexpected steel, stone or require scaffolding?

7. Do you offer an annual service package and what does it cost?
   

How to Avoid Surprises

• Reserve parking near both indoor and outdoor work areas for the installer’s van.

• Clear furniture and confirm a safe power-off for drilling through walls.

• Check mains board capacity and arrange a dedicated fused spur if needed.

• Obtain landlord or council approval where properties are leasehold, listed or in conservation areas.

• Confirm trunking colour/route in writing to avoid aesthetic disputes.

• Warn neighbours of possible one-day noise from drilling and vacuum pumps.
