Heat Pumps
Heat pumps are able to extract heat from soil, rock, air or water by a process that is similar to the operation of a refrigerator. They require electricity from another source to operate, but will extract more energy than is input.
Ground Source Heat Pumps
You will not require planning permission for the installation, alteration or replacement of a Ground Source Heat Pump within the curtilage of a dwelling house or a building wholly occupied by flats.
Water Source Heat Pump
You will not require planning permission for the installation, alteration or replacement of water source heat pump within the curtilage of a dwelling house or a building wholly occupied by flats.
Air source heat pump
This is interim guidance only, pending the development of an Industry Standard and the further expansion of Permitted Development for Domestic Microgeneration.
Air source heat pumps may need planning permission, depending upon the dimensions of the external air-handling unit proposed. You are advised to contact the Planning Help Line on 0114 2734215 for further advice.
Biomass boilers
Biomass boilers use wood fuel. The boiler is internal to the building and does not require planning permission. However the installation, alteration or replacement of a flue forming part of a biomass heating system on a dwelling house or building wholly occupied by flats will require permission if:
- The height of the flue would exceed the highest part of the roof by one metre or more.
In addition to this, if your property is located within a Conservation Area or World Heritage Site then permission will be required if:
- The flue would be installed on a wall or roof slope forming the principal or side elevation of the dwelling house and would be visible from a highway.
The construction of covered fuel storage units may need planning permission.
Combined Heat and Power System
Combined Heat and Power (CHP) is the simultaneous generation of usable heat and power in a single process. This system can be installed in a dwelling house and is highly efficient as the energy is both used and produced on site and reduces the amount of energy wasted through transmission.
The installation, alteration or replacement of a flue, forming part of a combined heat and power system, on a dwelling house or building wholly occupied by flats will require permission if:
- The height of the flue would exceed the highest part of the roof by one metre or more.
- In addition to this, if your property is located within a Conservation Area or World Heritage Site then permission will be required if:
- The flue would be installed on a wall or roof slope forming the principal or side elevation of the dwelling house and would be visible from a highway.
