Devon is a stiffened polyester vertical blind fabric, the kind of workmanlike cloth you find in offices and conservatories up and down the country. It rotates on a top track to control light and slides cleanly across wide openings or patio doors - exactly where vertical blinds earn their keep.

Three UK retailers - Swift Direct Blinds, Blinds By Post, and So Easy Blinds - all sell a vertical blind they call Devon. The colour palettes are a strong clue: Blinds By Post and So Easy Blinds list the same four shades (Whisper, Sand, Denim, Shadow), while Swift Direct Blinds stocks three overlapping names (Whisper White, Sandstone, Shadow Grey). That degree of overlap, combined with the way prices scale predictably with window area across all three, strongly suggests these retailers are sourcing what is likely the same wholesale fabric. No manufacturer is named by any of them, and the similarity cannot be confirmed absolutely - but the evidence points clearly in one direction.

Because the fabric is almost certainly fixed regardless of where you buy, the decision comes down to three things the price table below handles directly. First, colour availability: Swift Direct carries three shades; the other two carry four, adding Denim to the palette. Second, fittings: all three currently offer standard fitting only, so there is no difference there to resolve. Third, and most importantly, the headline "from" price is measured at the smallest available size - once you enter your actual window dimensions, the price ranking can shift. A retailer that looks more expensive on the listing page may undercut the others at your specific width and drop.

Measure carefully, price each retailer at your exact size, and pick the colour that suits the room.

We match these on the shared name and a price that scales the same way across window sizes, not an independent inspection, so treat it as likely the same fabric rather than confirmed. Construction, exact colourway and fitting can vary between retailers - check the specification at each before buying.
