Class D – Water source heat pumps on residential
Water source heat pumps are permitted development and do not require planning permission. Unlike other permitted development rights there are no restrictions in conservation areas or listed buildings unless an Article 4 exists or a restriction via a previous planning permission. They can also be installed within the curtilage of a block of flats.
If it is a listed building you will probably still require listed building consent for your water source heat pump.
As you can see from the very limited legislation there are no conditions within Class D for water source heat pumps.
And that it that on Class D!
For the commercial version of this, please see Class M of Part 14.
Class D – installation or alteration etc of water source heat pumps on domestic premises
D. The installation, alteration or replacement of a microgeneration water source heat pump within the curtilage of a dwellinghouse or a block of flats.
