The "GPDO Part 14 Classes A and B - LDC Appeal Decisions" document has been updated to include 1 additional appeal decision relating to solar panels on domestic premises, for which the conclusions are as follows:

November 2025 - Code P14CAB-022 (appeal dismissed):

• This appeal decision provides an example of where a house (or block of flats) has deteriorated to a certain extent, and the Inspector concluded that the property no longer benefits from Part 14 Classes A and B of the GPDO.
  [Note: The Inspector states that the property “was a two-storey end-terraced dwelling until fire resulted in the collapse of much of the building several years ago”].
  [Quote: “[The application site] was a two-storey end-terraced dwelling until fire resulted in the collapse of much of the building several years ago. Evidence indicates that the remains of the building were all that existed on the date of the application. Existing drawings of the dwelling are as it previously existed, not what exists on site. If the dwelling as it was, existed on site then the application would be considered against the provisions of Class B of Part 1 and Class A of Part 14 of Schedule 2 of the GPDO to judge whether the proposed development is permitted under the GPDO. Class B of Part 1 relates to, for this case, the enlargement of a dwellinghouse and Class A of Part 14 relates to, for this case, the installation of solar PV panels on a dwellinghouse. The crucial factor in both instances is that the permitted development right applies to a dwellinghouse It was found in Gravesham BC v SSE and O’Brien [1982] 47 P&CR 142 that the distinctive characteristic of a dwellinghouse was its ability to afford to those who used it the facilities required for day to day private existence. Under this judgement what exists on the land is not a dwellinghouse. [...] The issue of abandonment has been referred to by both parties. The residential use of the plot has not been abandoned. But there does not exist on site a dwellinghouse to sustain the residential use. Permitted development rights under Class B of Part 1 and Class A of Part 14 of Schedule 2 of the GPDO are for works to a dwellinghouse. There is no dwellinghouse on the land which can benefit from these permitted development rights. In these circumstances an LDC cannot be granted.”].
