This is in England and it actually was a certificate of lawful development that I put in rather than a full planning permission application. I was advised to go down that route by the planning department. I suppose that because selecting this particular location falls foul of that rule, a lawful development application might not be suited to considering the counter arguments about why it shouldn't be considered a problem. Perhaps a full planning application would be the better option?

I live in a conservation area and I put in a planning application last year for a heat pump, but it was refused on two grounds; 1. it being inside the one metre rule and 2. the location being between the line of the house and a highway. The exact wording for the second refusal came from Schedule 2 G.2 j(ii); “in the case of land within a conservation area or which is a World Heritage Site the air source heat pump—would be installed so that it is nearer to any highway which bounds the curtilage than the part of the dwellinghouse or block of flats which is nearest to that highway; or” I understand that the motive behind this rule is to prevent units being installed in front gardens or somewhere that would be visible from the actual road. In this case though, I want to install it in the back garden and the highway in question runs down the side of the property. If it was located there it would be at ground level, behind a 6ft fence which in turn is behind an 8ft hedge so there is no issue of visibility. I’ll add a drawing to show the arrangement. I have no other location that I can place the unit and now that the 1 metre rule has gone I would like to try again to get permission. Would anyone have any experience of this or advice on how to go about countering this objection? Thanks.
