The Trinity (Blackout) Twist&fit Roller Blind is a made-to-measure blackout roller blind sold by 247 Blinds, distinguished by a no-drill Twist&fit fitting mechanism designed for UPVC double-glazed windows. With 42 colours available from £20.93, it sits at the accessible end of the market for anyone who needs genuine light blockage without putting screws into their window frame.

Who it suits

The main case for this range is bedrooms - particularly for shift workers, young children, or anyone who finds early summer dawns a problem. The retailer describes the fabric as blackout, meaning it should block light transmission through the material itself; bear in mind that even a blackout fabric will allow some edge-leak unless you also use side channels or a face-fix fitting that covers the whole recess opening. The Twist&fit mechanism fits inside the rubber gasket of a UPVC window without drilling, which makes it a practical option for renters or anyone reluctant to drill into UPVC frames.

The no-drill fitting does impose a restriction: it works on UPVC windows with the right gasket profile, but will not suit wooden or aluminium frames. If your windows are not UPVC double-glazed, you would need to look at a standard bracket-fixed roller instead. For children's rooms, confirm the cord-safety arrangement with 247 Blinds before ordering - UK regulations require cord-safe operation by design, and the specific mechanism (cordless, wand, or breakaway) matters in rooms with young children.

This range is less suited to living rooms or home offices where some daylight with the blind down is usually preferred; a light-filtering or dimout fabric would serve better in those rooms.

The colours

42 colours available

Forty-two colours is a wide palette for a single roller blind range, and the spread here genuinely covers distinct territory. Neutrals form the core - Fossil Grey, Oyster Grey, Flint, Ash, Stone, Taupe, Platinum, Shadow, and Silver give you several genuinely different readings of grey. Whites and off-whites (Cotton White, Off White, Vanilla, Ivory, Dove) offer subtle warmth variations. Blues range from pale Baby Blue through French Blue and Royal Blue to deep Navy and Prussian Blue, with Teal adding a green-leaning option. Warm tones include Mayan Brown and Truffle, with the bolder end handled by Garnet, Poppy Red, Plum, and Peony. Lime and Soft Green add a cooler accent.

Two further finishes exist beyond the forty listed here; the range is broad enough that most rooms and colour schemes should find a workable match.

With a from-price of £20.93, this range sits at the more accessible end of made-to-measure blackout rollers. Pricing scales with the dimensions you order, so a small bathroom window will cost noticeably less than a wide bedroom bay - use the grid to check your specific size.

How it compares

The Twist&fit fitting is the defining feature here; if you need a no-drill UPVC solution with blackout fabric, it narrows the field considerably. Against standard bracket-fixed blackout rollers from the same or other retailers, the trade-off is fitting flexibility: a drilled bracket fitting can go on any wall or frame material and usually allows more precise placement, while Twist&fit is constrained to UPVC gasket windows.

If thermal performance matters as much as blackout, a cellular or honeycomb blind provides measurably better insulation than a roller - but will cost more and cannot match the colour breadth this range offers. For the specific combination of no-drill UPVC fitting, genuine blackout fabric, and a wide colour choice, this range covers the ground well.

A note on care

Standard polyester roller fabrics of this type can be kept clean with a vacuum brush attachment to remove dust, and a damp cloth with mild soap for any marks. Avoid soaking the fabric. The Twist&fit frame can be wiped with a damp cloth. Check the care label when the blind arrives, as specific guidance from 247 Blinds takes precedence.

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.
