If you’ve requested a quote for plantation shutters on a bay window and the number came back higher than you expected for a “single window,” you’re not alone. Bay window shutter quotes catch people out more than almost any other configuration — not because companies are inflating the price, but because a bay isn’t one window. It’s three, four or five separate openings at an angle, each needing its own frame, panels and on-site fitting. This guide explains what UK homeowners actually pay in 2026, broken down by bay type, material and style.
For the broader picture on all shutter materials and window types, see our complete plantation shutters cost guide. This post goes deeper on bays only.
The Short Answer
If you want the numbers before the detail:
- Three-panel splay bay, faux wood, full-height — £600–£1,100 fitted (most common UK bay)
- Four-to-five-panel box bay, faux wood — £1,200–£2,000+ fitted
- Bow bay (curved), faux wood — £1,400–£2,500+ fitted (most complex geometry)
- Same bays in real wood — roughly 1.8–2.0× the faux wood figure
- Same bays in MDF — roughly 25–35% less than faux wood
- Pricing is per panel, not per bay — always ask for a panel count on the quote
Why Bay Shutters Cost More (And Why That’s Fair)
A flat casement window needs one shutter frame and usually two panels. A standard three-panel splay bay needs three separate frames — one per facet — with mitred corners where the angles meet. Each frame is manufactured individually, shipped as separate units, and fitted on site with shimming and adjustment to sit square.
That means more material, more factory time, more van space, and a fitter on your wall for longer. A three-panel splay bay typically takes half a day to install; a five-panel box bay can take a full day. None of that is padding — it’s the real cost of dressing a geometrically complex opening properly.
If a quote for a bay feels surprisingly cheap, that’s the red flag. It usually means the company hasn’t surveyed in person and has assumed standard sizes from a photo, or they’re quoting a single flat frame across the whole bay (which will look wrong and fit badly). A proper bay quote always comes from a physical survey.
Bay Types and What They Cost
Not all bays are the same shape, and the shape drives the price more than almost anything else.
Splay bay (angled sides)
The classic Victorian terrace bay: a centre panel with two angled side panels. Most common in Leicester streets like Clarendon Park and Stoneygate, and throughout Loughborough and Market Harborough.
- Three-panel splay, faux wood, full-height — £600–£1,100 fitted
- Three-panel splay, faux wood, tier-on-tier — £650–£1,200 fitted
- Three-panel splay, real wood — £1,100–£2,200 fitted
- Three-panel splay, MDF — £450–£750 fitted
Box bay (square projection)
A flat front with two return sides — common on 1930s semis and larger Edwardian homes. More panels across the front means a higher total.
- Four-panel box, faux wood — £900–£1,500 fitted
- Five-panel box, faux wood — £1,200–£2,000+ fitted
- Five-panel box, real wood — £2,200–£4,000+ fitted
Bow bay (curved)
A gentle curve rather than hard angles. Requires more custom shaping and is the most expensive standard bay type.
- Three-to-five-panel bow, faux wood — £1,400–£2,500+ fitted

The photo above is a typical three-panel splay bay — each facet gets its own shutter frame and panels. Box bays typically cost more than this because they have more panels across the flat front, more frames, and more fitting time. A splay bay looks more complex but often has fewer total panels.
Cost by Material (Same Bay, Different Price)
Using a typical three-panel splay bay as the benchmark:
| Material | Typical fitted range | Best for |
|---|---|---|
| MDF | £450–£750 | Dry living rooms, tight budgets |
| Faux wood | £600–£1,100 | Most UK bays — best all-round value |
| Real wood | £1,100–£2,200 | Period homes, premium finish |
| Aluminium | £1,800–£4,000+ | Security bays, conservatories |
For the honest verdict on when MDF is and isn’t worth it, see our MDF shutters guide. For aluminium bays (security-focused ground-floor openings), see our aluminium shutters buyer’s guide.
Cost by Style
Material isn’t the only variable. Style affects the price on a bay too:
- Full-height — baseline price for the bay type and material.
- Tier-on-tier — usually 5–15% more than full-height on the same bay, because each panel has two tiers instead of one. The most popular choice on street-facing ground-floor bays.
- Café-style — usually 25–35% less than full-height, because the shutter only covers the lower half. Works well on ground-floor bays where you want maximum light from the top.
- Solid panel — can be slightly less than louvred styles, but uncommon on bays because it blocks too much light from the angled facets.

Tier-on-tier on a street-facing bay is the configuration we fit most often in Leicestershire terraces. The upper tiers let morning light in; the lower tiers keep passers-by from seeing in at sofa height. For a real local install, see our Leicester bay case study. For the full style comparison, see full-height vs tier-on-tier.
What Should Be on Your Bay Window Quote
A professional bay shutter quote should include:
- Bay type identified — splay, box or bow, with a panel count per facet.
- Material and style — specified per opening, not assumed.
- Fitted price — supply and fit, not supply-only unless you’ve asked for that.
- Frame type — recess-fit or face-fit, and why.
- Timeline — survey to installation, in weeks.
- Warranty — length and what it covers.
If any of those are missing, ask before you sign. Bays are too complex for vague quotes.
Red Flags on Cheap Bay Quotes
- No home survey — bays cannot be quoted accurately from photos or standard sizes.
- Single frame quoted across the whole bay — each facet needs its own frame.
- Price per window, not per panel — opaque pricing hides the real breakdown.
- Significantly below the ranges in this guide — ask what material and what panel count they’re assuming.
- No mention of on-site adjustment — bays always need shimming; if the quote doesn’t allow for it, the fitter will rush.
Bay Shutters in Leicestershire: Local Context
Victorian and Edwardian terraces with front bays are everywhere in our patch — Clarendon Park, Stoneygate, Westcotes and New Walk in Leicester; the older streets around Loughborough town centre; the period stock in Market Harborough and Oakham. Rear box bays on 1930s semis are common in Quorn, Mountsorrel and the Charnwood villages.
We’ve fitted hundreds of bay shutters across the county. If you want to see a recent example, our Leicester bay installation case study walks through a three-panel splay from survey to finish.
