Almost every bay window is dressed one blind per face, measured and aligned so the pattern or the slats run true across the angles. Vertical blinds are the most fitted because they draw and tilt on each face independently and a three-faced bay is exactly what the three-for-£99 offer covers; plantation shutters are the premium answer; Perfect Fit blinds suit uPVC bays with no drilling. The option to avoid is a single blind stretched across the opening, which leaves the angles uncovered and the sill unusable.
The five options compared
| Option | How it is fitted on a bay | Best for | Price pointer |
|---|---|---|---|
| Vertical blinds | One headrail per face, louvres tilt and draw on each | Street-facing living rooms, patio-door bays | Three plain verticals fitted for £99 in the current sale |
| Roller blinds | One roller per face, inside the recess | Bedrooms and kitchens, blackout or moisture-resistant | Three plain rollers fitted for £119 in the sale |
| Perfect Fit blinds | A frame clips into each pane’s glazing bead, no screws | uPVC bays, tilt-and-turn windows, rented homes | Quoted per pane on the visit |
| Roman blinds | One roman per face, or one across a shallow bay | Period living rooms wanting a soft, curtain-like look | Quoted per blind; 20% off plain ranges in the sale |
| Plantation shutters | A frame and panels per face, joined at the angles | Privacy from the pavement, period homes, the long term | Priced per window on a free survey, fitted in 8–10 weeks |
One blind per face, or one across?
Fitting per face keeps the sill clear, lets each window open and closes the light gaps at the angles, so it is how we fit verticals, rollers, venetians and shutters on almost every bay. A single blind across the opening only makes sense on a very shallow bay or where the sill is not used, and it is nearly always a roman blind, fitted outside the recess with a few centimetres of overlap each side so no light leaks at the edges.
The angles are where bays go wrong
- Vertical blinds: the louvres of neighbouring faces meet at the angle. We cut the headrails so the end louvres sit flush rather than clash, and set the stack to draw away from the join.
- Roller and venetian blinds: a small gap at each angle is unavoidable with a straight rail, so we match the fabric or slat colour across the faces and keep the gaps to the minimum the brackets allow.
- Shutters: the only option with no gap at all, because the frames are joined at the angle with matching corner posts.
- Perfect Fit: each pane is framed individually, so the angles are covered by the window frame itself.
How we measure a bay
You do not need to measure. On the free visit we measure each face at three heights, check the recess depth so the mechanism clears the handles, and measure the angles so the headrails or frames meet cleanly. For shutters we also check the recess is square, which decides whether a standard frame or an L-frame is needed. The quote you receive is fixed and written, and it already accounts for the extra fitting time a bay needs.
What the sale offers cover on a bay
- Three vertical blinds for £99: one standard three-faced bay in a plain fabric, up to 6ft by 6ft per face, with wand control, measured and fitted.
- Three roller blinds for £119: the same bay in plain roller fabrics with chain control.
- Three day and night blinds for £269: a bay in plain zebra-stripe fabric, up to 5ft by 5ft per face.
- A five-faced bay uses five blinds, so the offer covers three of them and the other two are quoted at the same per-blind rate.
