The Boiler Prep Checklist
Complete these checks to speed up your booking. Toggle the checklist to track your readiness.
Locate Your Main Stopcock
Ensure the main water shut-off valve is accessible. Often found under the kitchen sink or in the pantry.
Identify Boiler Mounting surface
Check whether your existing boiler is mounted on a solid brick wall, timber stud wall, or hidden inside a kitchen cupboard.
Inspect Flue Location
Note if your current boiler flue exits straight through the wall (horizontal) or up through your roof (vertical).
Clear the Work Environment
Create safe access around the boiler installation site. Clear cupboards, shelves, and pathways.
