Start With the Window, Not the Shutters
The biggest mistake buyers make is choosing a shutter style before they understand the window they're covering. A bay window is not a flat window with a decorative curve. It is three or more panels set at angles, often in a period property, often with walls that have moved over a century or more. If you start with the shutters, you'll end up with gaps, sticking panels and a fitter who blames the plaster.
Bay window shutters are made-to-measure panels fixed inside each face of the bay, and they succeed or fail on how well the frame is surveyed before anything is ordered. At Caledonia Shutters, we survey homes across Scotland, from Glasgow tenements to Highland cottages, and the survey always comes before the style conversation. Skip that order and no amount of good taste will save the job.
Here's what most guides get wrong: they treat "what to look for" as a list of shutter features. The real answer is that the window dictates the brief, and the shutters answer it. So we start there.
How to Measure a Bay Window for Shutters
Measuring a bay window for shutters means recording the width, height, depth and angle of every face separately, because no two faces of a bay are identical. You measure each panel at three points (top, middle, bottom) and take the smallest figure, then repeat for height. Angles matter as much as dimensions: a bay that looks like a clean 45 degrees may actually sit at 42 on one side and 48 on the other.
The practical sequence:
Measure each face at top, middle and bottom for width
Measure each face at left, centre and right for height
Record the depth of the reveal on every face
Note the angle between faces with a digital angle finder
Photograph every corner, sill and any pipework or radiator
A common mistake is measuring the window opening rather than the reveal. Shutters usually sit inside the reveal, so that's the surface that matters. Getting this wrong is the single biggest cause of remakes.
Angles, Returns and Sills: What Trips People Up
The "return" is the side wall of the bay, the short section between the window face and the main wall. On older Scottish properties, returns are often out of square, and sills are rarely level. A good surveyor checks all three: the angle between faces, the return depth, and whether the sill runs true. If the sill slopes, the shutter frame needs packing, and that has to be planned before manufacture, not discovered on installation day.
If you're measuring yourself for a quote, send photos of every corner. It saves a return visit and it protects you from a quote built on guesswork.
Bay Window Shutter Styles and What Each One Does to Your Room
Bay window shutter styles change how a room feels more than any other decision you'll make. The style controls light, privacy and the visual weight of the window. Three options cover most homes.

Full Height, Tier-on-Tier or Café Style
Full height shutters run from top to bottom of the window in one panel. They give the cleanest line and the most privacy control, but they block the sill area completely.
Tier-on-tier splits the window into independent top and bottom sections. You can open the top for light while keeping the bottom closed for privacy. For street-facing Glasgow flats, this is usually the best balance.
Café style covers only the lower half of the window. It suits period properties where you want the original window proportions on show and light flooding the top.
Style | Best For | Light Control | Privacy |
Full height | Clean modern lines | Full | Highest |
Tier-on-tier | Street-facing rooms | Flexible | High |
Café style | Period proportions | Partial | Lower half only |
Pro Tip On a bay, you can mix styles across faces. Many of our customers use tier-on-tier on the two angled faces and full height on the centre. It follows the architecture instead of fighting it.
The Best Material for Window Shutters in Older Homes
The best material for window shutters in older homes is hardwood or a quality hardwood-core product, because older properties move with the seasons and the shutters have to move with them. Softwood and MDF can work in stable, modern rooms, but in a draughty Victorian or Edwardian property they're more likely to warp, swell or show every settlement crack in the surrounding plaster.
What matters more than the species name is the construction. A hardwood frame with a stable core handles humidity swings far better than a hollow panel. In Scotland, where homes swing between damp winters and drier summers, that difference shows up within a couple of years. Ask what the core is made from, not just what the surface is.
Where it falls short: no material fixes a bad survey. A premium hardwood shutter fitted to an out-of-square bay will still show gaps. Material is the second question, not the first.
Watch Out Don't choose purely on price per square metre. The cheapest quote often uses a thinner frame that flexes on wide bay faces, and you'll notice it every time you close the panels.
Bay Window Shutters Cost UK: What Actually Drives the Quote
Bay window shutters cost in the UK is driven by five things: the number of panels, the size and shape of each face, the material, the style, and how awkward the installation is. A three-face bay needs three separate frames, so it costs more than a single flat window of the same total width. Angled faces, deep returns and uneven walls all add labour.
Because pricing depends on your specific window, we quote per job rather than publishing a flat rate. You can see how our pricing works and request a tailored figure on the Caledonia Shutters pricing page. That's the honest way to do it: a bay is never a standard size.

Watch for these when comparing quotes:
Survey charges added later if the first visit wasn't detailed enough
Packing and making good around uneven reveals, quoted as an extra
Removal of old blinds or fittings treated as a separate line
Access surcharges for upper floors or remote locations
Delivery fees that appear only at the final invoice
Key Takeaway A transparent quote names every one of these upfront. If a company won't put the full scope in writing before you pay a deposit, that's your answer.
How to Judge a Shutter Company Before You Pay a Deposit
Judging a shutter company comes down to four checks: who measures, who manufactures, who installs, and what happens if something goes wrong. If those four answers point to different subcontractors, you have less control over the outcome and less recourse when it slips.
Ask directly:
Does your own team measure, or is it outsourced?
Where are the shutters made, and what's the realistic lead time?
Who fits them on the day, and are they employed or subcontracted?
What's the process if a panel doesn't fit on installation day?
In our experience, the companies that answer all four without hesitation are the ones that finish the job properly. The ones that get vague are the ones that leave you chasing.
For anyone searching for bay window shutters near me in Glasgow or across Scotland, the same test applies whether the company is local or national. What matters is whether the people who measure, make and fit are accountable to one another. That's how we run our in-house process at Caledonia Shutters, and it's why we can commit to lead times most of the market can't match.
Frequently Asked Questions
What type of shutters are best for bay windows?
It depends on the shape of the bay and how you use the room. Tier-on-tier suits tall Victorian bays because the top and bottom panels open independently, so you get light at the top and privacy at street level. Café style covers only the lower half, which works well where you want daylight but a screen from passers-by. Full height gives the cleanest line across all three faces of the bay. The deciding factor is usually the depth of the window reveal and whether the bay has angled side panels, since those need bespoke frames rather than standard ones.
How much do bay window shutters cost in the UK?
Pricing depends on the number of panels, the material, the style and how complex the bay is to frame. A three-sided bay needs more panels than a flat window, and angled sections take longer to template and fit, so both push the figure up. Rather than work from a national average, get an itemised quote that separates the shutters, the survey and the installation. Caledonia Shutters publishes its pricing on its website, and quotes are tailored to your budget and window layout.
Do bay window shutters reduce heat loss?
Shutters add a layer of still air between the glass and the room, which slows heat escaping through the window. In older Scottish properties with single glazing or wide sash gaps, that extra barrier makes a noticeable difference to draughts and cold spots near the window. The effect is greatest when the panels close flush against the frame with no gaps at the edges, which is why accurate templating matters more than the material you choose.
Can shutters be fitted to a bay window with a narrow frame?
Yes, but the frame depth decides how. Slim frames often suit a smaller louvre width so the panels do not look cramped, and some bays need the shutters mounted inside the reveal rather than on the face of the frame. Very shallow reveals can rule out certain styles altogether. A surveyor should check the depth at each of the three faces separately, because bays are rarely symmetrical and one side is often tighter than the others.
A bay window is unforgiving. Get the survey wrong and every panel shows it, which is why the companies that measure, manufacture and fit under one roof tend to deliver the most reliable results. Caledonia Shutters handles the whole process in-house, from design to installation, with made-to-measure shutters, transparent pricing tailored to your budget, and fitting teams that cover all of Scotland, including the Highlands and Islands.
