Best Blue Blinds for UK Windows: Our Picks for 2026

Blue is a broad brief. It covers ice-pale sky blues and deep midnight navies, muted duck eggs and vivid sapphires, coastal teals and near-black indigos. Narrowing down which blue blind actually suits a window - and which type of blind best serves the room - is where most buyers get stuck. This guide covers six blind types across six UK made-to-measure ranges, each chosen because it offers at least one strong blue option and stands up well on its own terms. It doesn't aim to be exhaustive across the whole UK market; it covers the ranges we've looked at in detail and where the blue selection is genuinely useful.

What "blue" means across blind types

Before comparing the picks, it's worth being clear about what blue can mean depending on the blind type in question.

For roller and day-and-night blinds, blue is a fabric colour - the shade you see when the blind is down. The lighter the fabric, the more light it admits even on a dimout or blackout weave, because a pale blue absorbs less heat than the same fabric in a darker shade. If you're buying blue for a south-facing room, a lighter finish like Smoke Blue or Sky Blue will keep things cooler than Midnight Blue when the sun is strong.

For venetian blinds, the "colour" is the slat finish - aluminium slats are dip-coated or powder-coated, so the blue is entirely consistent across the blind. Slat blinds give you light control without changing the fabric colour: tilt the slats closed and you block light regardless of the finish.

For roman blinds, the blue is often part of a pattern - a print, a stripe, or a woven texture - rather than a flat colour. The Laura Ashley range here illustrates this well: the blue options run from pale seaspray to deep midnight navy, and many prints combine blue with other colours, so "blue roman blind" actually encompasses a wide range of visual results. It's worth reading the individual finish names carefully before ordering.

For vertical blinds and pleated blinds, the blue is in the vane or pleated fabric - again a consistent, single-colour finish in most cases, though pattern options exist.

What to look for

Match the blue to the room's light exposure. A north-facing room will read most blues as cooler and slightly greyer than a south-facing room where the same fabric sits in warm direct sun. Pale blues - Brittany Blue, Sky Blue, Smoke Blue - tend to read warmly in good natural light; deeper navies - Midnight Blue, Indigo Blue - can make a bright room feel calmer without darkening it as heavily as a blackout roller.

Consider how much of the blind you'll see when it's raised. Roman blinds stack into concertina folds at the top of the window when raised; this makes the pattern or colour visible even when you want maximum light. A heavily patterned roman blind in a strong blue will remain a visual presence in the room. A roller or venetian blind, by contrast, retreats almost completely when raised, so its colour becomes irrelevant when it's up.

Think about opacity. Blue is a colour, not a light-control property. Most of the ranges here offer blue options across different opacity classes - from light-filtering fabrics that let diffused light through to heavier dimout options. The Splash Twist roller, for example, carries blue in a range that spans multiple fabric weights. Day-and-night blinds like the Enjoy are neither light-filtering nor full blackout: they give adjustable privacy by aligning or staggering their fabric stripes.

Check the vane or slat width for venetians and verticals. The Spirit venetian uses 25mm slats, which give a finer, more modern look than 50mm alternatives. The Bella vertical uses standard 89mm vanes. Neither width is inherently better - finer slats suit contemporary interiors; wider vanes suit large openings like patio doors where fewer, broader vanes move more cleanly.

Fitting type matters for colour matching. If you're fitting a blue blind inside the recess alongside existing woodwork, check whether the headrail or cassette colour coordinates. Most roller and venetian blinds have a white or grey mechanism by default; ask the retailer if a coloured or matching cassette is available if the headrail will be visible.

Pick details

Splash Twist Roller - Swift Direct Blinds

Best blue roller

Splash Twist Roller

at Swift Direct Blinds

Five blue shades from pale Smoke Blue to deep Indigo Blue, starting from under £9 - one of the widest blue selections in a roller range.

from £8.36 in 81 colours

Read review →

The Splash Twist is a wide-choice roller: 35 finishes in total, with four blue options spanning the main tonal range - Brittany Blue, Classic Blue, Midnight Blue, and Smoke Blue, plus Indigo Blue for those who want something closer to purple-blue. That spread is more useful than it first appears: Smoke Blue and Brittany Blue are pale enough to read as neutrals in a contemporary interior, while Midnight Blue and Indigo Blue have the depth to anchor a darker scheme.

This is a fabric roller blind, so the blue is flat and consistent. The range starts from under £9, making it accessible for multiple windows in the same room - practical if you're trying to match blinds across a bay or a set of identical windows. Because the price is per blind at your dimensions, the total cost scales with your window size, but the starting point is genuinely low.

Compared to the roman or venetian picks here, the roller retreats completely when raised. If you want a blue blind that disappears during the day, a roller is more discreet than a roman, which stacks at the top in visible folds.

Laura Ashley Blinds UK - Blinds By Post

Best blue roman

Laura Ashley

at Blinds By Post

134 blue finishes spanning pale Seaspray to deep Midnight Navy, including printed designs like Sail Boats and florals, from just over £20.

from £20.57 in 379 colours

Read review →

The Laura Ashley range at Blinds By Post is substantial - 134 blue finishes among a much larger total. The blue options run from pale, near-neutral shades like Fennelton Pale Newport Blue and Kate Pale Seaspray Blue through to mid-depth prints such as Conwy Blue Sky and Tulips China Blue, and on to the deeper navy options including Hawling Irises Midnight Navy, Lloyd Midnight Navy, and Summerhill Midnight Navy.

Roman blinds are inherently more decorative than rollers. The fabric folds as it raises, so there's more of it on show - and in the Laura Ashley range, many of the blue finishes are printed designs rather than flat colour. A'hoy Sail Boats Blue is a repeat print; Alford Meadow Delpinium Blue is a floral; Tiverton Stripe Midnight is a stripe. The finish name tells you quite a lot about the visual character, which is worth reading before ordering.

Starting from just over £20, this is more expensive than the roller pick and the venetian. The price reflects both the roman blind mechanism and the licensed fabric designs. For living rooms, bedrooms, or any space where you want the blind to add visual interest rather than disappear, the range justifies the additional spend. For a purely functional covering, a roller is likely sufficient.

When the blind is raised, the roman stacks into horizontal folds - the fabric and its pattern remain visible at the top of the window. In a blue print with strong contrast, this is a feature rather than a problem, but it's worth considering for rooms where you want clean glass when the blind is up.

Spirit Cool L-shaped Venetian - Blinds 2go

Best blue venetian

Spirit Cool L-shaped Venetian Blind - 25mm Slat

at Blinds 2go

A 25mm aluminium slat venetian in an L-shaped fitting - a practical choice for shallow recesses and moisture-prone rooms like kitchens or bathrooms.

from £8.60 in 16 colours

Read review →

The Spirit venetian is a 25mm aluminium slat blind, fitted in the L-shaped configuration that suits windows with a shallow or complicated recess. Aluminium venetians are practical in rooms where moisture is a factor - kitchens and bathrooms especially - because the slats wipe clean easily and aren't susceptible to warping. The L-shaped fitting is a specific solution for windows where a standard straight headrail can't be fitted cleanly inside the recess.

As a venetian blind, the blue is in the slat coating. The available finish is Spirit Cool White L shaped 25mm Slat - this is a white finish, included in the blue picks as part of a cool-toned category. If you specifically want a coloured blue slat, it's worth checking the retailer's full venetian range directly, as colour options vary across standard and specialist venetian models.

Venetians provide light control that roller and roman blinds don't: you can tilt the slats to admit angled light without raising the blind at all. In a kitchen or bathroom where privacy and light management both matter, this adjustability is a practical advantage over fabric alternatives.

Bella Vertical Blinds - Blinds By Post

Best blue vertical

Bella 127mm

at Blinds By Post

55 finishes including Brittany, Sapphire, Midnight and Duck Egg across a made-to-measure vertical range that starts from under £11.

from £11.00 in 55 colours

Read review →

The Bella range at Blinds By Post covers 55 finishes, and the blue options are well represented: Brittany, Empire, Midnight, Sapphire, and Tiffany cover a range of blue tones from softer mid-blues to deep navy. Duck Egg is also available for those who want blue-green rather than pure blue.

Vertical blinds are the natural choice for wide windows and patio doors, where the alternative - hanging multiple roller or roman blinds side by side - creates visual breaks and operational complexity. The vanes in a vertical blind slide along the top track and rotate to control light, so you get both traverse opening and tilt adjustment in one mechanism.

Starting from under £11, the Bella is among the more affordable picks in this guide. It's made-to-measure, so it'll be cut to your exact width and drop. The 55-finish range gives reasonable colour choice without being overwhelming; the blue selection hits the main tonal points without redundant overlap.

Vertical blinds suit a more casual or practical interior aesthetic - they're common in conservatories and home offices as much as living rooms. If the priority is covering a large opening efficiently and the blue colour is an accent rather than the centrepiece, a vertical blind is a sensible choice. If the blue needs to be a design statement, a roman or a day-and-night blind will carry more visual weight.

Pleated Fit - Swift Direct Blinds

Best blue pleated

Pleated Fit

at Swift Direct Blinds

Two blues - mid-tone Blue Clic and lighter Sky Blue Clic - in a no-drill perfect-fit pleated blind that suits UPVC windows and rented properties.

from £23.59 in 15 colours

Read review →

The Pleated Fit range at Swift Direct Blinds is designed for no-drill perfect-fit installation - the "Clic" suffix on the finish names indicates the clip-in fitting; "Stick" indicates a self-adhesive fitting. This is particularly useful for renters or for UPVC windows where drilling is either not permitted or not desirable.

Two blue finishes are available: Blue Clic and Sky Blue Clic. The tonal difference is meaningful - Blue Clic is a mid-blue, while Sky Blue Clic is a noticeably lighter and cooler shade. Both are in the Clic fitting configuration, so neither requires adhesive or drilling.

Pleated blinds suit windows where a minimal, clean look is the priority. The fabric stacks into compact folds at the top when raised, leaving more visible glass than a roman blind. At 15 finishes total, this is the smallest range in this guide, but for a no-drill blue pleated blind it covers the essential choice well.

At under £24 to start, and with the no-drill fitting factored in, the Pleated Fit is a sensible option for anyone who needs blue coverage without any permanent fixture. The limitation is colour choice - two blues is a narrow selection, and if neither shade suits the room, this range won't be the answer.

Enjoy Roller Blind (Day and Night) - Blinds 2go

Best blue day and night

Enjoy Roller

at Blinds 2go

Three blues - Midnight Blue, Navy and Teal - in a day-and-night stripe blind that adjusts between diffused light and direct privacy from under £13.

from £12.92 in 57 colours

Read review →

The Enjoy is a day-and-night blind - two layers of alternating sheer and opaque horizontal stripes. Adjusting the blind shifts the stripes relative to each other: align the opaque stripes and you block direct view through the window; stagger them and sheer stripes align for diffused light. The mechanism is a roller, so the operation is familiar.

Three blue finishes are available: Midnight Blue, Navy, and Teal. Midnight Blue and Navy are both deep, saturated tones - Navy being a slightly warmer, more conventional navy and Midnight Blue reading as closer to a near-black blue. Teal is the outlier: more blue-green than blue, useful if you want a blue blind that introduces some warmth.

Day-and-night blinds sit somewhere between a roller and a sheer in function. They don't provide full blackout - even with the opaque stripes aligned, the stripe pattern means some light passes at the stripe edges. For a living room, dining room, or home office where privacy matters but complete darkness doesn't, the Enjoy is a good fit. For a bedroom where genuine darkness is the goal, a different type would serve better.

Starting from under £13, the Enjoy is mid-priced among the picks. The 24 finishes in the range skew heavily towards neutrals and warm tones; the three blue options are a small fraction of the total. That's worth noting: if a specific blue is the priority, the narrower Splash Twist roller offers more blue shades for a similar or lower starting price.

What we didn't include

This guide focuses on made-to-measure fabric and aluminium blinds - the options that most UK households are actively looking for when they search for blue blinds. We haven't included wooden venetians, which offer some blue options but have material limitations in humid rooms (wood warps with moisture). We also haven't included smart or motorised options - these are available in some blue fabrics but represent a substantially different price point and a different buying decision, and the choice of motorisation is usually independent of the colour choice.

The guide covers the six blind types that give genuinely different results: roller, roman, venetian, vertical, pleated, and day-and-night. Panel blinds - the very wide sliding panels used for room dividers and extra-large openings - aren't covered here, as the typical use case is quite different from a standard window application.

Price by your window

Prices vary considerably depending on your window dimensions. All six picks are made-to-measure, so the starting prices listed (from under £9 for the Splash Twist to under £24 for the Pleated Fit) reflect the smallest available sizes. Larger windows will cost more, and the per-square-centimetre rate differs across blind types and retailers. Each pick's detail page includes a price grid showing costs at common sizes, which is the most reliable way to compare like-for-like for your specific window.
