Frequently asked questions

Do you need planning permission for solar panels on a house?
Most rooftop solar PV is permitted development if it doesn't project above the highest part of the roof or more than 200mm from the surface. Conservation areas, listed buildings and World Heritage Sites usually require full planning permission or Listed Building Consent.
Do you need planning permission for an air-source heat pump?
In most cases an outdoor heat pump unit smaller than 1.5m³ (raised in 2025 from 0.6m³) and at least 1m from the boundary qualifies as permitted development. Listed buildings and conservation areas may need full permission.
How big can a solar farm be without planning permission?
Ground-mounted commercial solar farms above 50kW effectively always require full planning permission. Smaller rooftop installations on industrial or agricultural buildings can sometimes use prior-approval rights under Part 14 of the GPDO.
