On-site install time for a typical domestic air source heat pump in the Lothians is around three to five working days.
What happens each stage:
- Day 1 — Delivery, outdoor unit siting and base preparation, indoor pipework routing
- Day 2-3 — Radiator swaps where needed, hot water cylinder install, system flushing
- Day 4 — Commissioning, controls set-up, weather compensation tuning
- Day 5 — Handover, walkthrough, paperwork
The wider project timeline — from first survey to a running system — is usually four to eight weeks:
1. Free home survey and heat loss calculation 2. Fixed-price quote with Home Energy Scotland eligibility reviewed 3. Home Energy Scotland application supported via JME Green Energy under their MCS certification 4. Install scheduled once funding is confirmed 5. Install + commissioning on site 6. Home Energy Scotland paperwork finalised, warranty and handover completed
We protect floors, clean up properly each day, and never leave a job half-finished between visits. You'll have a clear schedule before we start so you know exactly what's happening and when.
