The Windsor range from Blinds By Post is a made-to-measure vertical blind offered in 6 shades, starting from £23.50. A vertical blind hangs as a set of fabric louvres that tilt to angle the light and draw to one side to clear the window, which makes it a natural fit for wide expanses of glass. What sets this range apart from many verticals is the fabric: Windsor uses a blackout cloth, so each louvre blocks light rather than filtering it, and the palette leans into colour rather than staying strictly neutral.
Who it suits
Vertical blinds come into their own on wide windows, patio doors and conservatories, where the louvres tilt together to set the light and privacy you want, then pull aside as a stack to open the window or door fully. That sideways draw suits sliding doors in particular, where a blind that lifts would be in the way. With a blackout fabric, this range is aimed at rooms where you want to cut as much light as the format allows - a bedroom across a wide window, or a media room.
It is worth being clear about what blackout means on a vertical. The fabric itself blocks light, but vertical louvres leak a little where they overlap, so the result is a heavily darkened room rather than the total darkness a fitted blackout roller can give. For most rooms that is plenty; if you need every chink of light gone, a roller or pleated blind in a blackout fabric is the better tool. The louvres are individually replaceable too, so a single damaged slat can be swapped rather than the whole blind.
The colours
6 colours available
The range is a compact set of six shades that, unusually for a vertical, leans towards colour. There are two blues in Navy and Teal, a warm Rust, a soft pink in Blush, a green in Vine and a neutral Oatmeal to anchor the group. So rather than a wall of neutrals, this is a small palette built to bring some character to a wide window while still keeping the blackout fabric. Oatmeal covers the quiet, easy-to-place option, while Navy, Teal, Rust, Blush and Vine each let the louvres carry the colour. Colour on a screen and colour filling a window can differ, so request a sample before committing to a full-sized blind, particularly with the stronger shades here where the difference is most noticeable.

The range sits at an accessible entry point, consistent with vertical blinds more broadly, which tend to be among the more affordable made-to-measure types for covering a large window. There is a single standard fitting across the range, so the price you see is driven mainly by the width and drop of your window rather than the shade you choose.
How it compares
Against a standard light-filtering vertical, Windsor's blackout fabric darkens a room far more, which makes it the better choice where light control matters and the colour suits the scheme. Against a roller blind, a vertical offers tilt control the roller cannot, and draws to the side rather than lifting, which suits patio and sliding doors. The trade-off remains the light that leaks at the louvre overlaps, so for true blackout across a smaller window a blackout roller would edge it. For wide glazing where you want both real darkening and a bit of colour, this range fills a gap that neutral verticals do not.
A note on care
Vertical louvres are easy to keep tidy. Dust them regularly with a soft brush or the upholstery attachment of a vacuum, running down the length of each louvre, and spot-clean marks with a damp cloth and a little mild detergent, working gently so as not to stretch the fabric. Take the louvres off their hooks if you want to clean them flat, and let them dry fully before rehanging. Because the louvres are individually replaceable, a single one that is stained or damaged beyond cleaning can be swapped out without replacing the whole blind.
Likely the same fabric, at other retailers
Windsor vertical blinds are sold under the same name by more than one UK retailer, and the price scales identically across window sizes - a strong sign it is the same fabric from the same supplier:
- Blinds Direct from £15.56
- Blinds By Post this page from £23.50
- Wilsons Blinds from £25.64
- Vertical Blinds Direct from £71.36
We match these on the shared name and an identical price curve, not an independent inspection, so treat it as likely the same fabric rather than confirmed - and check the specification and colour at each retailer before buying.
