This page is about the job rather than the bill. What replacing windows in Edinburgh actually involves, in what order, and which of the rules you will be quoted at are real here and which were written for England. The money sits on a separate page: our double glazing cost in Edinburgh breakdown covers the per-window and whole-house figures, and this page does not repeat them.
What is different about replacing windows in Edinburgh
Edinburgh has around 50 conservation areas, including the UNESCO World Heritage Site covering the Old and New Towns. That is the highest density of any city we cover, and in the research conservation-area density is the single most powerful driver of regional cost variation, because a larger share of homeowners are pushed into premium timber or heritage frames by planning rules rather than by preference.
The practical effect is a reordering of the job. Everywhere else, a homeowner decides on a material, gets three prices for it and picks one. In large parts of Edinburgh the material is decided first, by someone else, and only then does price become a question. The standard uPVC casement that most window content is written around is not the default product in the historic core: timber sash and case is, and it is a different purchase with a different lead time, a different set of installers and a price several times higher.
Start with the consent question, not the quote
The first action in an Edinburgh window replacement is not measuring openings. It is confirming your property's conservation and listed status with the City of Edinburgh Council. Where either applies, planning consent can be required before any change and like-for-like timber sash and case may be the only permitted option, so the answer determines the product, the lead time and the budget in one go. Getting quotes before you have it produces three prices for a job you may not be allowed to buy.
Our conservation area rules guide sets out the general position and the arguments conservation officers tend to accept, such as like-for-like timber, heritage aluminium and slimline units in a matching sightline. Read it as background: the planning machinery it describes is the English one, and planning in Scotland is administered separately. Take the binding answer for your address from the council, not from a national guide and not from a salesperson.
Scottish rules are not English rules, and most window advice is English
This matters more in Edinburgh than almost anywhere, because so much of what a homeowner here reads and is told was written for a different legal system.
Certification. FENSA is authorised for England and Wales only, and Scotland operates a separate system under Scottish building standards. Our FENSA explained guide covers the English scheme in the detail our sources support, and it is honest about the limit: we can describe the England and Wales route far more precisely than the Scottish one. So do not treat a promised FENSA certificate as proof of anything in Edinburgh. Ask the installer, in writing and before you pay a deposit, which route they are certifying under and exactly what document you will hold when the job is signed off.
Rental standards. The minimum energy efficiency standard changes that drive the EPC C deadline coverage apply to England and Wales. Scotland runs a separate regime. An Edinburgh landlord being sold windows against an English deadline is being sold against the wrong rule.
Building regulations. Building standards are devolved. The Approved Document L and Part L figures published elsewhere on this site are English regulations, quoted because most of our readers are in England. They are not the compliance test for a window fitted in Edinburgh, and no quote you receive here should cite them as if they were.
The Edinburgh quotes we check fall into two piles that barely look like the same job. One prices a uPVC casement the property may not be allowed to have; the other prices timber sash and case at several times the figure. Reading them side by side without first knowing the property's planning status is not comparing quotes, it is comparing guesses.
Double Glazing Cost Calculator Team
What the job costs, in short
Enough to plan with, then a link. Scotland runs about 8% belowthe UK average, and Edinburgh's conservation areas add roughly 8% back, leaving the city within about 1% of the national figure at £400-£990 per uPVC window fitted and £3,970-£9,940 for a typical 3-bed. Timber sash and case is the figure that actually decides most Edinburgh budgets. The full breakdown, including style-by-style pricing and the sash numbers, is on the double glazing cost in Edinburgh page. To price the two products the historic core actually uses, the sash window calculator and the timber window calculator are the right tools rather than the casement figures.
Replacement is not always the right job here
In a city with this much protected stock, the honest sequence is repair first, secondary glazing second, replacement third. Two findings support that, and one of them is Scottish: Glasgow University research commissioned by English Heritage and Historic Scotland found secondary glazing outperforms replacement double glazing for thermal efficiency in traditional buildings. Secondary glazing also leaves the original window untouched, usually needs no planning permission at all, and can cut noise by around 80%. It runs about £300 to £900 per window fitted, with DIY supply orders from around £164, against the replacement figures above. The full comparison is on secondary versus double glazing.
If your windows are original sashes that are draughty or sticking rather than rotten, repair is usually the cheaper and less contentious route, and it sidesteps the consent question entirely. That job has its own page: sash window repair in Edinburgh.
Paying for it through the Scottish schemes
The grant landscape is devolved too, and the schemes named in most UK window articles are English. The one that applies here is Home Energy Scotland, which offers an interest-free loan of up to £8,000 towards upgrading single glazing to double or triple glazing. A £1,500 rural uplift raises that to up to £9,500 for remote rural, island and off-grid accessible rural areas, which will rarely apply to a city address but may to properties on the edges of the region. The non-repayable grant portion is no longer available for windows specifically.
Two limits worth knowing before you build a budget around it. It is for owner-occupiers only: landlords and developers cannot use it, and instead have a separate Private Rented Sector Landlord Loan of up to £38,500 which includes £4,500 towards single-glazing upgrades. And it is a loan, not free money, so it changes the cash flow of an Edinburgh timber sash job rather than the price of it.
Choosing an Edinburgh installer
The like-for-like rule matters more here than anywhere. In most cities three quotes differ on price; in Edinburgh two of them can be for different products, because one firm has assumed uPVC is permitted and another has priced heritage timber. A quote that is a fraction of the others is usually the wrong window rather than a better deal. Our guide to three like-for-like quotes covers how to force them onto the same specification, and the quote quality auditor flags what a written quote leaves out.
Three questions worth asking every Edinburgh firm, in this order. Whether they have completed consented work in city conservation areas, and can evidence it. Whether they manufacture or supply timber sash and case, since a uPVC-only firm cannot serve a large share of Edinburgh addresses whatever their price looks like. And what completion paperwork you will hold at the end, given that the English certificate most window content describes is not the Scottish one. We do not recommend individual companies and do not publish ratings for them, so treat the answers as your own filter.

Frequently asked questions
It depends entirely on your address. Edinburgh has around 50 conservation areas, including the UNESCO World Heritage Site over the Old and New Towns, which is the highest density of any Scottish city. Where conservation or listed status applies, planning consent can be required before any change and like-for-like timber sash and case may be the only permitted option. Confirm your property's status with the City of Edinburgh Council before you take a single quote, because the answer decides which product you are buying.
No. FENSA is authorised for England and Wales only, and Scotland operates a separate system under Scottish building standards. Ask your installer in writing which scheme or route they are certifying the work under and exactly what completion paperwork you will hold at the end, rather than assuming the FENSA certificate described on English window sites will arrive.
Home Energy Scotland offers an interest-free loan of up to £8,000 towards upgrading single glazing to double or triple glazing, rising to £9,500 with the £1,500 rural uplift for remote rural, island and off-grid accessible rural areas.

It is open to owner-occupiers only; landlords use the separate Private Rented Sector Landlord Loan of up to £38,500, which includes £4,500 towards single-glazing upgrades.
Not as written. Those minimum energy efficiency standard changes apply to England and Wales, and Scotland runs a separate regime. Treat any English EPC deadline quoted at you by a salesperson in Edinburgh as background rather than as the rule that governs your property.
It can be, and the research behind that is partly Scottish. Glasgow University research commissioned by English Heritage and Historic Scotland found secondary glazing outperforms replacement double glazing for thermal efficiency in traditional buildings. It leaves the original window in place, usually needs no planning permission, and runs about £300 to £900 per window fitted, with DIY supply orders from around £164.
