Discover the Perfect Vertical Blinds for Your Home

Vertical blinds are the workhorse of window coverings: affordable, practical, and ideal for wide windows and sliding or patio doors. But buying well means getting the details right — material, measurements, controls, and (crucially in the UK) child safety. This guide covers what to choose, what it costs, and how to fit them.

Quick Buying Checklist

• Measure: decide inside vs. outside recess mount; measure width and drop in three places, use the smallest for inside mounts.
• Material by room: vinyl/PVC for kitchens and bathrooms (moisture-resistant); fabric for living rooms and bedrooms (softer light); aluminium for a sleek, modern look.
• Vane width: standard 89 mm (3.5-inch) vanes; wider vanes give a cleaner look with fewer slats.
• Controls: wand control is the safer, tangle-free default — recommended for homes with children or pets.
• Stack direction: stack vanes to the side away from the door handle; choose split stack for French doors or symmetrical windows.
• Safety: all new blinds in the UK must meet child-safety standards (see below).
• Budget: roughly £18–£180 per window made-to-measure; £30–£100 per window for professional fitting.

How Much Do Vertical Blinds Cost in the UK?

Option	Typical price
Made-to-measure, small window (standard fabric)	from ~£18
Made-to-measure, average window	~£64
Made-to-measure, very large window / patio doors	up to ~£180
Supplied and fitted per window	~£60–£180
Professional fitting only (per window)	~£30–£100

Premium fabrics (thermal, blackout-coated, PVC, fire-retardant) cost more, as do motorised tracks. Figures based on UK retailer pricing (English Blinds, The Blind Tailor, 2025–2026); prices vary by size and fabric.

Materials: Which Is Right for Each Room?

• Fabric vanes: soft, light-filtering, widest choice of colours and textures. Best for living rooms and bedrooms. Need gentler cleaning.
• Vinyl/PVC vanes: moisture-resistant and wipeable. The practical choice for kitchens, bathrooms, and utility rooms.
• Aluminium vanes: sleek, reflective, and durable with a contemporary feel. Good for offices and modern interiors.

For colours, neutrals (white, cream, grey) suit most décor and help resale; bolder colours work as an accent but date faster. Match the vane tone to your wall colour for a seamless look, or contrast deliberately for definition.

Measuring: Inside vs. Outside Mount

• Inside (recess) mount: the blind sits within the window recess — neat and minimal. Measure the width and drop in three places (top, middle, bottom) and use the smallest measurement so the blind fits.
• Outside mount: the blind overlaps the recess — better for blocking light at the edges and for shallow recesses. Add overlap (typically 5–10 cm each side) to your measurements.
• Check the recess depth is sufficient for the headrail, and note any obstructions (handles, tiles).

Wand vs. Chain Controls

Wand control tilts and draws the vanes with a single twist-and-pull wand — no looped chain to tangle, making it the safer default for homes with children or pets. Looped chains are still common but must be fitted with safety devices (see below). If you choose a chain, it should be secured with a tensioner or cleat so no hazardous loop can form.

Vane Widths, Stack Direction, and S-Shaped Vanes

• Standard vanes are 89 mm (3.5 inches) wide. Wider vanes mean fewer slats and a cleaner, more contemporary look.
• Stack direction: vanes gather (“stack”) to one side when open. Stack them on the side away from the door handle on sliding doors. Split stack (vanes parting in the middle, like curtains) suits French doors and wide symmetrical windows.
• S-shaped vanes overlap when closed, reducing light gaps and giving a softer, fabric-like appearance — worth considering if light seepage bothers you.

Light Control and Privacy — With One Caveat

Tilting the vanes gives excellent graduated light control: angle them for diffused daylight, open fully for a clear view, close for privacy. One honest limitation: vertical blinds are poor blackout performers compared with roller blinds, because light inevitably seeps between the vanes. For bedrooms needing true darkness, consider blackout roller blinds or curtains instead — or in addition.

Child Safety: UK Law

This is non-negotiable. Since 28 February 2014, blinds sold in the UK must comply with BS EN 13120:2009+A1:2014: they must be “safe by design” (no hazardous cord/chain loops) or supplied with fitted safety devices such as cleats, cord tensioners, or chain-break connectors. The rules were introduced after a number of tragic child strangulation accidents involving blind cords (RoSPA records 27 UK deaths linked to blind cords since 1999).

• Choose wand-operated vertical blinds where children are present — no looped chain at all.
• If you have a chain-operated blind, fit the safety device properly: tensioners screwed to the wall so the chain is held taut, or cleats with the cord wound in a figure of eight after every use.
• Keep cots, beds, and play areas away from windows with corded blinds.
• Older, pre-2014 blinds aren’t covered retrospectively — but you can retrofit safety devices, and landlords have a duty of care to ensure rented properties are safe.

Installation: DIY or Professional?

Vertical blinds are among the more DIY-friendly window coverings: you’ll need a drill, screwdriver, tape measure, level, and appropriate wall fixings (plasterboard anchors for stud walls, masonry plugs for brick). The critical step is accurate measuring (see above). Call a professional if the window is very large, the wall material is uncertain, or you want a perfect finish — fitting typically costs £30–£100 per window.

Cleaning and Maintenance

Vinyl and aluminium vanes: dust regularly and wipe with a damp cloth. Fabric vanes: vacuum with a brush attachment; spot-clean stains gently and check the manufacturer’s guidance before wet-cleaning. Don’t be swayed by “dust-repellent” marketing claims — all blinds need periodic cleaning. Check the headrail track occasionally for smooth operation; aluminium headrails tend to outlast folded-steel ones.

Are Vertical Blinds Dated?

It’s a fair question — but modern vertical blinds have moved on from the flimsy office blinds of the 1990s. Contoured headrails, high-performance fabrics, S-shaped vanes, and motorised options have kept them a current choice, particularly for patio doors and wide windows where curtains are impractical. In the right setting they look clean and intentional, not dated.

Frequently Asked Questions

How much do vertical blinds cost?

Made-to-measure vertical blinds run from around £18 for a small window to £180 for very large ones; supplied-and-fitted is typically £60–£180 per window.

Are vertical blinds good for blackout?

Not really — light seeps between the vanes. For true darkness, choose blackout roller blinds or curtains.

How do I measure for vertical blinds?

Decide inside vs. outside mount, then measure width and drop in three places and use the smallest figure for inside mounts.

Are vertical blinds safe with children?

Yes, if compliant: UK law (BS EN 13120, since Feb 2014) requires new blinds to be safe by design or fitted with safety devices. Wand-operated blinds are the safest choice.

Can you get motorised vertical blinds?

Yes — remote-controlled and smart-home-compatible tracks exist, at a premium over manual controls.
