The Trinity (Blackout) Roller Blind is a made-to-measure fabric roller sold by 247 Blinds, available in 42 colours and carrying a from-price of £9.72. What distinguishes it within the blackout-roller category is the sheer breadth of the colour offer: neutrals, blues, greens, pinks, reds, and whites all sit in the same range, so it can work across a variety of rooms without requiring a different product line.

Who it suits

The obvious fit is a bedroom - the retailer describes the fabric as blackout, meaning it is designed to block light transmission through the material itself. That matters most where you need genuine darkness: shift workers sleeping through daylight hours, young children whose sleep is disrupted by early summer mornings, or anyone sensitive to street lighting overnight. Worth noting that no blackout fabric, however opaque, eliminates all room light on its own; edge gaps around the blind let light through regardless of the fabric. For the darkest result, fitting inside the recess on a close-fitting bracket or combining with a heavier curtain will help more than fabric choice alone.

The range also suits home offices and living rooms where moderate light control is useful but blackout is not essential - a blackout fabric works fine in a room where darkness is only an occasional need. It would be a poor choice for bathrooms unless the fabric is a PVC or coated type; moisture resistance is not confirmed for this fabric, so steer towards a purpose-made bathroom roller in wet rooms.

Children's rooms are a reasonable fit given the blackout benefit for sleep, but check the operation type before buying: cord-operated blinds sold for domestic use must be cord-safe under UK regulations, and for a child's room the safer choice is a cordless or wand-operated option if the retailer offers it on this range.

The colours

42 colours available

The palette is unusually varied for a single blackout roller range. The blue group alone covers Baby Blue, Delph Blue, French Blue, Navy, Prussian Blue, Royal Blue, and Teal - enough range to suit anything from a soft nursery to a dark, richly coloured bedroom. Greys are equally well represented: Ash, Flint, Fossil Grey, Light Grey, Oyster Grey, Platinum, Shadow, Silver, Soft Grey, Steel, and Stone give a considered spread from pale off-white-grey through to near-charcoal. Warm neutrals run from Ivory and Vanilla through to Taupe and Truffle.

The bolder options - Fuschia, Garnet, Lime, Peony, Poppy Red, Plum - are genuinely distinct rather than variations on the same hue. One finish is omitted from the listed sample, so the full count on the retailer's site may show a slightly extended selection. No colour is flagged as premium-priced, so the from-price applies across the palette rather than being exclusive to the entry-level colours.

Price by your dimensions

With a from-price at £9.72, the Trinity Blackout sits at the budget-friendly end of the made-to-measure roller market. As with most made-to-measure pricing, the cost rises as width and drop increase - the widget above shows how your specific dimensions affect the price. Smaller windows will come in near the from-price; a large bedroom window will cost noticeably more, which is standard for any made-to-measure range.

How it compares

Within the blackout-roller category, the Trinity's main differentiator is colour breadth: most budget blackout rollers offer a narrower palette, typically greys, whites, and one or two accent colours. If the exact colour match matters - say, coordinating with painted walls or existing soft furnishings - the 41-colour offer is a practical advantage over a range with six or eight options.

Where the Trinity is likely weaker is against ranges marketed specifically on fabric weight or texture. A heavier, more substantial blackout fabric will hang more cleanly, show fewer creases after installation, and resist flapping in a draught better than a lighter-weight alternative. A GSM (fabric weight) figure is not published, so we cannot say where this fabric sits on that scale. If hang quality and rigidity are priorities, it is worth checking the retailer's fabric sample service before committing to a larger order.

For rooms where genuine thermal performance matters as well as light control - a conservatory, a cold north-facing bedroom - a cellular or honeycomb blind would outperform any single-layer roller fabric on insulation. The Trinity is a light-control product; it is not designed as an energy-saving blind.

Fittings for this fabric

The same fabric and blind type is sold in more than one fitting:

  • Standard from £9.72 fixed with drilled brackets
  • No-drill (twist-fit) from £20.93 about +£12 on the standard blind clips onto a UPVC frame, no screws
  • Motorised from £115.30 remote or app control

No-drill and clip-in fittings suit UPVC windows and renters, but they cap out at the largest window sizes - check the maximum drop before ordering for a tall window.
