Listed buildings
Plumbing and heating work on listed buildings
A listed building boiler flue in Edinburgh may need listed building consent if it affects the building's character, and the City of Edinburgh Council, not your installer, decides whether it does.
By the Pipes Up the Stair site team · how pages are checked · Updated
Large parts of central Edinburgh are listed, in a conservation area, or both, and from Leith to the Southside plenty of tenement flats sit inside one. That changes how a new boiler flue, extract fan or heat pump can be fitted, and sometimes whether it can be fitted at all.
Nothing here means a job is permitted. Ask the council before work starts.
Does a new boiler flue on a listed building need consent?
It may, so ask first. The council's guidance says listed building consent is required for any internal or external work that will affect a listed building's character, and doing such work without consent is a criminal offence. We couldn't confirm a specific council rule for flue terminals on listed or conservation-area frontages, so treat any flue through a front wall as something to raise with the council in advance.
What work rarely needs consent?
Matching repairs and modern rooms. The same guidance says repairs that match the original materials and methods, and replacing modern kitchens and bathrooms, would rarely require consent. Rarely is not never, and moving a bathroom or adding new pipes and vents can change the picture.
Where should new kitchens, bathrooms and fans go?
Towards the back. The council would rather see a new kitchen or bathroom placed at the back of the building, to avoid cluttering a front elevation with downpipes and ventilators. It says mechanical extractor fans belong on rear or side walls and not in windows, fanlights or on front elevations. For moisture problems, see condensation and damp.
Can pipes be run through old plaster?
Not through the decorative kind. Discussing sprinkler systems in historic interiors, the council says pipework should not be cut into decorative plasterwork, and the same care makes sense for any new heating or water pipe near cornices and ceiling roses. Historic Environment Scotland lists internal alterations that affect the character of the building among works almost certainly needing consent.
How many conservation areas does Edinburgh have?
Fifty. The council says there are 50 in Edinburgh, and its list of character appraisals includes the Old Town, New Town, Marchmont, Meadows and Bruntsfield, Leith, Dean, West End, Southside and Morningside. Only Leith and Inverleith have management plans. The council also warns that not all permitted development rights apply within a conservation area.
Who do you apply to?
The council, as planning authority. Historic Environment Scotland says you must apply to your planning authority for listed building consent before making changes that may affect character, not to Historic Environment Scotland itself. It counted more than 46,500 listed building records in Scotland in March 2026, and more than 600 conservation areas.
What about heat pumps?
They face the tightest limits. Going by the rules in the Scottish Government's May 2024 circular, Planning Circular 1/2024, there are no permitted development rights for a heat pump in a World Heritage Site or within the curtilage of a listed building, and Edinburgh has two World Heritage Sites: the Old and New Towns, and the Forth Bridge. The council adds that units should generally not go on principal elevations. More on heat pumps in flats.

Asked on the stair
Is it a crime to fit a flue without listed building consent?
If the work affects the building's character and needed consent, the council's guidance says doing it without consent is a criminal offence. That is why asking first matters.
Does every Edinburgh conservation area have a character appraisal?
No. The council counts 50 conservation areas, but its appraisal list has fewer entries than that.
Can Historic Environment Scotland grant consent directly?
No. It says applications go to the planning authority, which in Edinburgh is the City of Edinburgh Council.
Does a modern bathroom in a listed flat need consent to replace?
The council says replacing modern kitchens and bathrooms would rarely need it, but check if pipes, vents or walls change.
