Blinds By Post sells the Twistfit Blackout as a made-to-measure pleated blind in 7 colours, starting from £46.78. Where most blackout blinds reach for roller or venetian mechanisms, this range uses a pleated fabric that stacks compactly when raised - a practical advantage in rooms where a roller's bulky tube would sit awkwardly. The retailer describes the fabric as blackout, meaning it should pass a backlight test through the material itself, though edge-leak is always a factor to consider independently of fabric opacity.
Who it suits
The Twistfit Blackout is a natural fit for bedrooms, including children's rooms, where blocking early-morning light matters most. As with any blackout blind, the fabric opacity is only part of the equation: light will still enter around the edges unless you use a perfect-fit frame, side channels, or an outside-recess fitting that laps generously onto the wall. The pleated format stacks neatly when raised, which makes it a reasonable option for narrower windows where a roller blind would look top-heavy when open.
The palette of neutral and cooler tones suits living rooms and home offices too, particularly where some daytime glare control is wanted without full blackout. That said, if light filtration rather than full blackout is the actual requirement, a dimout or light-filtering pleated blind would leave more flexibility; blackout fabric can make a living space feel cave-like during the day.
This range is not suited to bathrooms or kitchens. Pleated blinds - especially fabric ones - are not moisture-resistant, and grease vapour from a kitchen will accumulate in the pleats over time.
The colours
7 colours available
The range covers seven finishes: Natural Beige, Sky Blue, Carbon Black, Pebble Grey, Slate Grey, Stone Grey, and Soft White. The palette is firmly neutral and interior-safe - three distinct greys, a warm beige, an off-white, a bold near-black, and one colour departure in Sky Blue. The three grey options (Pebble Grey, Slate Grey, Stone Grey) are close enough in name to warrant checking swatches carefully before ordering, as the visible difference between them may be subtle depending on your room's light conditions. Sky Blue is the one genuinely distinctive choice if you want the blind to contribute something to the room rather than disappear into it. Carbon Black delivers strong contrast for modern interiors and should be the most effective of the seven at reducing light bleed through the weave itself.

Starting from £46.78, the Twistfit Blackout sits at a mid-market entry point for a made-to-measure pleated blackout blind. Pricing will rise with width and drop as the made-to-measure grid reflects actual fabric use, so it is worth measuring accurately before comparing against other options at similar sizes.
How it compares
Against a standard blackout roller blind, the Twistfit Blackout's main practical advantage is its lower stacked height when raised - pleated fabric takes up less vertical space than a roller wrapped around a tube, which matters in rooms with low window heads. The trade-off is that roller blinds are generally simpler to clean (a flat wipe-down) and a wider range of blackout fabrics tend to be available in the roller format.
If thermal performance is a priority alongside blackout, a honeycomb (cellular) blind in a blackout fabric would outperform a standard pleated blind on insulation, because the sealed air pockets in a honeycomb structure reduce heat transfer in a way that single-layer pleated fabric cannot match. The Twistfit Blackout does not appear to claim honeycomb construction, so treat it as a single-layer pleated blind and manage expectations on insulation accordingly.
For anyone whose main concern is truly complete darkness - shift workers, babies, anyone sensitive to any light at all - a blackout roller or venetian on an outside-recess fit, with the overlap covering any gap around the recess, will reliably outperform any inside-recess pleated blind on total room darkness.
