Conservatories in Glasgow: planning, conservation areas and installers

Permitted development in Glasgow

Scotland has its own permitted development order. Class 1A covers single-storey ground-floor extensions, which the Scottish Government’s guidance says includes conservatories. In summary, Planning Circular 1/2024 says extensions are generally to the rear; if any part is on or within 1 metre of a boundary it cannot project more than 3 metres from the rear wall of a terraced house or 4 metres in other cases; the eaves can be no higher than 3 metres and the extension no higher than 4 metres; all extensions together cannot have a larger footprint than the original house; and development cannot cover more than half of the rear (or front) garden. There are no Class 1A rights for flats, and the circular notes that a building warrant will likely be needed for this type of extension. See how Scottish permitted development differs from England.

Conservation areas in Glasgow

Glasgow City Council says the city currently has 25 conservation areas, ranging from the city centre and Victorian residential suburbs to a rural village (Carmunnock) and a former country estate. Many cover Victorian suburbs where conservatories are common: in the West End, Park, Glasgow West, Woodlands, Broomhill, Scotstoun and Victoria Park; on the south side, East and West Pollokshields, Strathbungo, Crosshill, Dumbreck, Millbrae and Newlands; and Dennistoun in the east.

The Scottish rules are stricter than England’s here: Class 1A permitted development does not apply at all in a conservation area. So in any of Glasgow’s 25 conservation areas, a conservatory of any size needs a planning application. The council also says Article 4 directions are in place in most conservation areas to control minor alterations, and that listed building consent is needed as well if the building is listed. Its conservation area appraisals, which it treats as a material consideration in planning decisions, describe what the council expects in each area.

Planning and building warrant fees in Glasgow

Scottish planning fees are set nationally and rose on 1 April 2026:

Sources: The Town and Country Planning (Fees for Applications) (Scotland) Amendment Regulations 2026 (legislation.gov.uk); building warrant fee table from 1 April 2026 under the Building (Fees) (Scotland) Amendment Regulations, as published by Renfrewshire Council (renfrewshire.gov.uk). Councils may check the value of work you declare against published building cost indices.

Do you need a building warrant? Under the April 2026 domestic Technical Handbook, a single-storey conservatory or porch attached to a house can be built without a warrant only if it is 8 square metres or less, at least 1 metre from a boundary, and has no flue, fixed combustion appliance or sanitary facility, and its glazing meets the safety rules. Anything bigger needs a warrant from Glasgow City Council’s building standards service before work starts; mygov.scot says starting such work without one is an offence. Read building warrant exemptions for conservatories in Scotland.

Tenements and flats. Much of Glasgow’s housing is tenement flats, which have no householder permitted development rights, and shared back courts are usually common property. A ground-floor conservatory would normally need planning permission and the agreement of the other owners.

Typical private prices

We have not found a price survey for Glasgow alone, so use the national ranges in our UK conservatory costs guide. Checkatrade’s 2026 figures put a 3.5m by 3.5m uPVC lean-to at £9,000–£11,500 and a uPVC Victorian at £12,000–£13,500. At those values, a building warrant for a conservatory that is not exempt would sit in the £391–£539 bands of the national scale, before any planning fee.

How to choose an installer in Glasgow

• Ask who deals with the warrant. If the conservatory is over 8 square metres or within 1 metre of a boundary, ask whether the firm will prepare the building warrant drawings and apply, and who signs the completion certificate.
• Ask about planning in conservation areas. In any of Glasgow’s 25 conservation areas, a conservatory needs planning permission. Ask to see the design and materials before the application goes in.
• Glazing standards. FENSA and Certass certificates relate to the building regulations in England and Wales. In Scotland, ask how the glazing will meet the Technical Handbook’s safety glazing and energy standards.
• Written quote and payment stages. Get at least two quotes to the same specification and agree payment stages: see surveys, contracts and payment stages.
