Planning permission is one of those topics where a thirty-second Google search gives you answers from English websites that don't quite apply in Scotland. The Scottish system has two separate consents, planning permission and the building warrant, and a typical kitchen renovation interacts with neither, one, or both depending on what you're actually doing.
This guide isn't legal advice, Glasgow City Council, East Dunbartonshire, East Renfrewshire and South Lanarkshire each have their own teams and case-by-case judgement, but it should give you a clear sense of which side of the line your project sits on.
Planning permission vs. building warrant, the difference
Scotland separates them deliberately:
- Planning permission deals with how a building looks from the outside and how it affects its surroundings extensions, dormer windows, change of use, external alterations.
- Building warrant deals with how the work is done to comply with the Scottish building standards, structure, drainage, electrics, ventilation, fire safety. It's about safety and quality, not aesthetics.
A pure kitchen refit, new units, worktops, appliances, all in the same room, needs neither. The trouble starts when the scope grows.
When you almost certainly don't need either
- Replacing existing units, worktops and appliances
- Re-tiling or replacing flooring
- Decorative changes, paint, splashbacks, lighting fittings
- Like-for-like sink and tap replacement
- Replacing an existing extractor on the same route
When you probably need a building warrant (but not planning)
- Removing an internal load-bearing wall to open the kitchen up to a dining or living space. Structural calcs, a steel or timber beam, and a warrant.
- Forming a new opening in a load-bearing internal wall.
- New drainage runs beyond minor adjustments adding a utility room sink, moving the kitchen waste a significant distance.
- Electrical work that triggers a notice under building standards, full rewires, certain new circuit installations.
- Installing a wood-burning stove or range cooker flue in a previously unused chimney.
When you may also need planning permission
- A new extension to enlarge the kitchen. Some single-storey rear extensions fall under "permitted development" and don't need planning, but the limits are tighter than people think, particularly in conservation areas.
- Listed buildings. If your property is A, B or C listed, almost any meaningful internal or external change requires listed-building consent, including some things that wouldn't otherwise need planning (removing original panelling, altering original kitchens or sculleries, changing fireplaces). The penalties for unauthorised work to a listed building are serious.
- Conservation areas. Parts of the West End, Pollokshields, the city centre and many town centres are designated conservation areas. External changes, extraction flues penetrating front elevations, new rooflights, alterations visible from the street, typically need consent.
- Flat conversions (tenement and main-door). The tenement deed often restricts what you can do to common parts and shared services. Always check the title deeds before specifying anything that goes through the building fabric.
Tenement flats, the special case
Tenements add a layer beyond planning and building warrant: the Tenement (Scotland) Act and your title deeds. Common considerations:
- External venting through a sandstone external wall typically needs neighbour notification and may need planning consent
- New waste runs into shared stacks may need notification to other owners
- Working hours and access to the close are usually governed by deed
Building warrants, the practical process
A warrant application typically takes 6–10 weeks to process in most Scottish councils, plus the time to prepare drawings and structural calculations. If your project needs a warrant, build that lead time into the schedule, don't expect to commence work the week you submit the application.
The honest summary
About 70% of kitchen projects we deliver in Glasgow need neither planning permission nor a building warrant. About 25% need a warrant for an internal wall removal or significant drainage changes. About 5%, listed buildings, conservation-area extensions, large structural projects, need full planning consent. The right answer for your project comes from a proper survey and a chat with whoever's designing it.
