The Banlight Duo FR (Blackout) Perfect Fit Roller Blind is sold by So Easy Blinds as a no-drill blackout roller that clips into UPVC double-glazed windows using the Perfect Fit frame system. With 30 colours available and a from-price of £84.86, it sits in the upper portion of the made-to-measure roller market - the price reflects the Perfect Fit hardware and a fabric the retailer describes as both blackout and fire-retardant.

Who it suits

Perfect Fit is a clip-in frame system that grips the rubber gasket of a UPVC double-glazed window - no drilling, no screws, and fully removable without trace. That makes this range a natural fit for rented properties and for anyone unwilling to drill into UPVC frames. The constraint is the same as any Perfect Fit blind: it requires UPVC windows with a compatible gasket profile and sufficient recess depth for the frame. Wooden or aluminium window frames are not compatible.

The blackout fabric is the other key claim here. The retailer describes it as blackout, which means it should be opaque to a backlight test; verify this with So Easy Blinds if your use case is demanding, as "blackout" terminology is used loosely in the market. Even with an opaque fabric, some edge-leak is possible with any fitting that doesn't run flush to the wall - Perfect Fit minimises this by sitting close to the glass, which makes it more effective at reducing edge-leak than a standard recess bracket fitting.

Bedrooms are the primary use case - especially for light sleepers, shift workers, or young children affected by early mornings. For children's rooms specifically, confirm the cord-safety arrangement with So Easy Blinds: UK regulations require cord-safe design, and the specific mechanism used in this range needs checking before installation in a room with young children.

Living rooms and home offices would generally be better served by a dimout or light-filtering roller, where some daylight coming through the fabric is a positive rather than a problem.

The colours

30 colours available

Thirty colours cover a broad neutral-to-accent range. Greys dominate: Charcoal, Grey, Pale Grey, Stone Grey, Ultimate Grey, Concrete, and the deeper Anthracite and Iron give seven distinct grey readings. Whites and near-whites (Bright White, White, Vanilla) and beige-adjacent tones (Biscotti, Calico, Linen, Nude, Sand) provide a generous range of pale options. Blues span Glacier Blue, Smokey Blue, Navy, Ocean, and Marina. Greens are represented by Lichen, Desert Sage, and Green. Warmer accents include Dijon, Old Gold, and Rose, with Iris and Redcurrent adding stronger colour at the purple and red ends. Black completes the palette.

This is a plain-colour range with no patterned options; the strength is the breadth of neutrals and the ability to match most interior schemes.

Price by your dimensions

Made to measure from £84.86. Check So Easy Blinds for the price at your exact window size.

At £84.86 from-price, this is towards the higher end for a made-to-measure blackout roller, which is consistent with the combination of Perfect Fit hardware, fire-retardant fabric, and a 30-colour choice. The from-price applies to smaller sizes; larger drops and wider windows will cost more.

How it compares

The distinctive factor here is the combination of blackout fabric and Perfect Fit fitting. Many blackout rollers use standard bracket fitting, which requires drilling and typically allows more light around the edges of the blind. Perfect Fit's close-to-glass position reduces that edge-leak, making it a more thorough option for rooms where complete darkness matters.

If cost is the primary concern, a standard-bracket blackout roller from any of the main retailers will generally come in at a lower from-price - but will need drilling and will sit further from the glass. If the no-drill requirement is firm but budget is tight, other no-drill approaches (Twist&fit, standard clip-in systems) exist at lower price points, though typically without the fire-retardant rating.

The FR (fire-retardant) designation may also be relevant for landlords or commercial installers; confirm the specific certification with So Easy Blinds for any compliance purpose.
