The Celeste Ultra Blackout is a made-to-measure roller blind sold by 247 Blinds, positioned squarely at the blackout end of their range. It comes in 10 finishes and starts from £24.95, making it one of the more accessible entries in the site's blackout roller offering. The range carries the "Ultra Blackout" label - the retailer's designation for their opaque fabric tier - and the two available finishes are both neutral in tone, aimed at buyers who want function over decoration.

Who it suits

The obvious fit is the bedroom - anyone who needs genuine darkness to sleep, whether that's shift workers, young children, or anyone in a room that catches early morning light. A blackout fabric will block transmission through the material itself, though it is worth bearing in mind that no roller blind eliminates edge-leak entirely. If you need complete room darkness, combining this blind with side channels or a heavier curtain will help.

It works equally well in a nursery or child's bedroom, where controlling morning light can make a significant difference to sleep patterns. For those rooms, check whether you prefer a cordless or wand-operated version for cord safety - 247 Blinds' product listing will confirm the available operation types for this range.

It is less obviously suited to living rooms or home offices, where light filtering rather than full blackout tends to serve better. The palette - see below - is calm and neutral rather than decorative, so it will not add much visual interest if that is what a living room needs. In a bathroom or kitchen, the blackout function is usually unnecessary, and a PVC or moisture-resistant fabric would be a more practical choice.

The colours

10 colours available

The two finishes are Celeste (Blackout) Talc and Eclipse (Blackout) Fern. Talc is a pale, warm off-white - the kind of neutral that recedes quietly against light-coloured walls and window frames. Fern is a muted green with earthy, slightly grey undertones rather than a vivid botanical shade.

The choice between them is essentially warm neutral versus a soft earthy green. Neither is a statement colour, which may be exactly what you want in a bedroom where you are not trying to make the blind the centrepiece. If you need something darker or need a wider palette, this particular range does not expand beyond these two finishes.

Price by your dimensions

Enter your window size. We round up to the next standard size, which matches how the retailer actually quotes you.

The range opens at a modest from-price, which puts it at the accessible end of the blackout roller market. As with all made-to-measure blinds, the price will step up as width and drop increase - the widget above shows how pricing scales across common sizes so you can estimate what your specific window dimensions will cost before ordering. Both finishes sit at the same base price point, so your colour choice does not affect what you pay.

How it compares

Against other blackout roller blinds in a similar price bracket, the Celeste Ultra Blackout is a straightforward, no-frills option: a deliberately tight colour selection, clear blackout positioning, and a competitive entry price. If you want a broader palette, 247 Blinds and other retailers carry larger blackout ranges with a dozen or more finishes; this range is for buyers who have already decided on the colour and want a tidy, reliable blackout fabric rather than variety.

If thermal performance is also a priority - particularly for a north-facing room or an older single-glazed window - a cellular or honeycomb blind would outperform any roller fabric on insulation. Rollers, including this one, will reduce convection slightly but are not in the same category as a structured cellular blind for heat retention.
