What installers quote for
What can you get quoted for in Scotland?
Scottish installers quote for replacement windows, sash and case windows, new sealed units and repairs, for a single room or a whole house.
- Replacement windows in uPVC, aluminium or timber: see casement window replacement for the most common style.
- Sash and case windows, renewed or replaced: see sash window replacement.
- Glass-only or sealed-unit replacement for misted panes in sound frames.
- Repairs to hinges, handles, locks and seals.
Some window firms do not fit doors, so ask the installer whether a front or back door can go on the same quote.

What changes a Scottish double glazing quote
Six things change a double glazing quote in Scotland: no FENSA, a different energy target, Class 7A planning rights, flats and tenements, disrepair and how you pay. Settle each one before the survey, so every quote prices the same job.
| In Scotland | What it changes in your quote | Ask or check |
|---|---|---|
| England and Wales, FENSA's stated remitFENSA | No FENSA certificate for Scottish windows | A written statement that the windows meet the Scottish standards |

Planning
Do you need planning permission for replacement windows in Scotland?
Most Scottish window replacements need no planning application. The Scottish Government states that like-for-like windows "will not require an application for planning permission. This is the case in all locations", and Class 7A permitted development covers most other swaps "of a house or flat" (Planning Circular 1/2024).
That differs from England, where new windows in a flat that differ in appearance or size from the old ones may need a planning application (Planning Portal). In Scotland, three cases still need a step first:
- Conservation areas: rear windows, and side windows that do not front a road, carry no design restriction. A front window that changes its opening method, its panes, or its frame size or colour means notifying the council first. The council has 28 days to say whether it needs to approve the design; if it does not reply in that time, you can go ahead.
- World Heritage Sites: there are no permitted development rights for replacement windows there, as our page on double glazing in Edinburgh explains for the Old and New Towns.
- Listed buildings: listed building consent is needed "irrespective of whether planning permission is needed".
Class 7A covers changes to existing windows, not new openings. Ask each installer who notifies the council for a conservation-area job and who prepares the description and plan it asks for.

Building standards
Do new windows need a building warrant in Scotland?
No building warrant is needed to replace a window with its frame in Scotland, but the new window must still meet the building standards in full. The domestic Technical Handbook lists "a door, window or rooflight when the work includes replacing the frame" as work not requiring a warrant, and says complete replacements "have to meet the full requirements of the standards".
The energy target is where Scottish quotes differ from English ones. Replaced windows should reach a U-value of 1.6 W/m²K, or a Window Energy Rating of band C or better (Technical Handbook, clause 6.2.11). England's limit is 1.4 W/m²K or band B (Approved Document L), so a spec sheet written for England may quote a different figure.
- Ask for the U-value or energy band of every window on the quote. You can ask for a better figure than the minimum.
- Replacing only one or two windows to match the rest? The frame can be left out of the assessment if each glazed unit's centre-pane U-value is 1.2 W/m²K or less.
- Glass-only work that is not a complete replacement must be no worse than what it replaces.
- For historic buildings, the handbook says "like for like" may still be permitted where windows must match.

Flats and tenements
Window quotes for tenement flats in Scotland
Tenement owners check their title deeds and speak to their factor before asking for quotes, so every installer quotes a window the building will accept. Tenements are a large part of the Scottish stock: the Scottish House Condition Survey counts 177,000 pre-1919 tenement flats (7% of homes), and 582,000 tenement flats make up around 28% of urban housing (SHCS 2024).
Older homes have the most to gain. Only 23% of pre-1919 Scottish homes are rated EPC C or better (SHCS 2024).
- Read your title deeds for window ownership and any style condition.
- Ask your factor about the building's window policy and planned common repairs.
- Ask installers to price rear windows as separate lines: in a conservation area they carry no design restriction.
City by city, see double glazing quotes in Glasgow for tenements and the factor, and Aberdeen double glazing quotes for granite flats and weather-tight specs.

Paying for windows
Paying for new windows: the Home Energy Scotland loan
Home Energy Scotland offers no grant for glazing, only an interest-free loan, and only for improving single glazing. Its funding page says the loan is "NOT for replacement/improvement of existing double. triple or secondary glazing", and the applicant must own the home and live in it as their only or primary residence.
Trading Standards Scotland has warned about social media adverts for windows and doors offering discounts to Scottish consumers, including one promising "help to buy windows", and it points people to Home Energy Scotland for free, impartial advice. Our sister site explains how the Home Energy Scotland loan works for windows.

Before they quote
How to check a Scottish installer without FENSA
Check a Scottish installer on paper: the company record, a written standards statement and the guarantee. FENSA describes its work as covering England and Wales, and a replaced window needs no building warrant, so there is no FENSA certificate or warrant to lean on.
- Search the company named on the quote at Companies House.
- Get written confirmation that the windows meet the Scottish building standards, with the U-value of each window.
- Ask whether the guarantee is insurance-backed, and which insurer stands behind it.
- Ask for recent jobs on homes like yours.
Our page on double glazing installers covers the full checks, and the guide on how to compare double glazing quotes shows what a full quote lists.
If you sign at home, you usually have at least 14 days to cancel, but made-to-measure windows can be an exception, so check the contract before you sign: see the double glazing cooling off period.

FAQ
Scotland double glazing questions
Who will contact me after I ask for quotes?
A short call confirms the job first. Local installers who cover your postcode then contact you to book a survey and send a written quote.
Are there any grants available for double glazing in Scotland?
Home Energy Scotland states that grant funding is not available for glazing. It offers homeowners an interest-free loan, and only for improving single glazing.
Can I get a Home Energy Scotland loan to replace existing double glazing?
No. Home Energy Scotland says the loan is only for improving single glazing, not for replacing or improving existing double, triple or secondary glazing.
Can I get free windows and doors in Scotland?
Not through Home Energy Scotland, which offers no grant for glazing. Trading Standards Scotland has warned about social media adverts offering window and door discounts, and recommends Home Energy Scotland for impartial advice.
Do Scottish installers give a FENSA certificate?
FENSA describes its remit as England and Wales. In Scotland a replacement window with its frame needs no building warrant but must meet the building standards, so ask for that confirmation and the U-values in writing.
Can I replace the windows in my own flat in Scotland?
Usually yes: Class 7A permitted development covers the windows of a house or flat. Check your title deeds and speak to your factor first, and check for a conservation area, a listed building or a World Heritage Site.
How much does it cost to replace windows in Scotland?
The cost follows the number of windows, the frame, the glass and the access, so compare written quotes for the same specification from at least three installers.
