Class M – Water source heat pump on commercial

 

Water source heat pumps

Water source heat pumps are permitted development and do not require planning permission within the cutilage of commercial property. 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.  

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 is only one condition within Class M for water source heat pumps on commercial property and that is the total surface area covered must not exceed 0.5 hectares.

And that it that on Class M!

For the residential version of this, please see Class D of Part 14.
