📋 What the Rules Say for Heat Pump Installations
In Wales, air source heat pumps are generally classed as Permitted Development — meaning no planning application is needed, as long as:
✅ The unit is less than 0.6m³ in size
✅ It’s installed more than 1 metre from the boundary
✅ It’s not on a flat roof or visible from a highway
✅ It’s the only ASHP on the property
🚫 When You Don’t Need Permission
🏡 Most semi-detached and detached Cardiff homes
🏢 New builds or modern extensions
🌿 Homes with a garden space or outdoor wall
These properties can typically install heat pumps freely — with no paperwork required.
⚠️ When Planning Approval Might Be Required
You may need permission if:
🏛️ You live in a conservation area or listed building
🏙️ You want to install multiple heat pumps
🪟 Your unit is placed on a flat roof or near a public footpath
🔄 You’re replacing a system that already needed permission
