Ground or water sourced heat pumps
The installation of ground or water sources heat pumps within the grounds of a dwelling or flat will normally be regarded as "permitted development" and would not need planning permission.
However, if permitted development rights have been withdrawn you will need to apply for planning permission.
If the property is a listed building or the proposal is within the grounds of a listed building you might need to have listed building consent.
Building control
This specialised installation involves utilising energy from subsoil pipes to assist with water heating.
This is classed as the provision or extension of a controlled service or fitting and building regulation approval is required.
Full specifications, energy efficiency appraisal, and specialist consultant details will be required along with electrical details (except if a Part P competent person is used).
