FAQ

What size curtains do I need for my room?+

Measure the width of your window, adding at least 15cm to each side for fullness. For height, measure from the floor to just above your curtain rail – typically 16-24cm is ideal.

What are the most common materials for curtains and blinds under £20?+

You'll mostly find polyester or cotton blends for curtains, offering affordability and easy care. Vinyl blinds and basic woven roller blinds fall within this price range.

How much should I expect to pay for quality curtains?+

You can typically get ready-made curtain panels for around £15-£30, while a DIY kit might cost £8-£15. Customisation will naturally increase the price.

How do I care for polyester curtains?+

Polyester is relatively easy to care for – machine wash on a gentle cycle with cold water and mild detergent. Avoid high heat during drying.

What about blinds? Are they worth the investment?+

Vinyl blinds are incredibly budget-friendly, offering simple light control. Roller blinds provide better light blocking and can be found within this price range too.

Are blackout curtains available at this price point?+

You'll find basic roller blinds with a slight blackout effect around the £20 mark. True blackout linings are often more expensive, but you might find some budget options.

How do I measure for Roman blinds?+

Measure the width of your window and add 5cm to each side. For height, measure from the curtain rail to the desired blind position – typically 10-15cm is sufficient.

What are the best curtains for summer versus winter?+

Lighter, breathable fabrics like cotton or linen are ideal for summer months to reflect sunlight. For winter, consider heavier thermal curtains to retain heat.

Are there any safety regulations I should be aware of with blinds?+

For children’s rooms, ensure cords are out of reach and secured properly, or opt for cordless blinds to eliminate this risk – check current UK regulations.

Can I compare the light control offered by different blind types?+

Roller blinds offer the most precise light control, while Venetian blinds allow you to adjust the level of visibility. Curtains provide a softer, diffused light effect.

In depth

The selection process for these ‘best’ curtsies & blinds under £20 centres around a pragmatic assessment of value – not necessarily luxury. Given the price point, we've prioritized products offering a reasonable balance between materials, construction quality, and aesthetic appeal. Our core criteria involves measuring durability against expected lifespan, assessing fabric performance concerning our notoriously changeable UK climate, and evaluating overall ‘fit’ for typical UK homes. We don’t shy away from acknowledging compromises; at this budget, you won't find top-grain leather or bespoke tailoring – we look for solid foundations and functional design. Importantly, we've considered the practical needs of British homeowners: space constraints are common in older properties, while larger, newer homes demand solutions that can manage both light levels and privacy effectively.

Several key considerations differentiate buying curtains & blinds in the UK from other markets. Foremost is our climate – a damp, often overcast environment necessitates fabrics with moisture resistance and UV protection. Thermal linings, crucial for energy efficiency, are increasingly important due to rising heating costs. Furthermore, British homes tend to be smaller on average than those found in, say, Scandinavia or North America; therefore, compact blinds and lightweight curtains that don’t overwhelm a room are highly desirable. We've also factored in the prevalence of older properties with restrictive planning regulations regarding window treatments – simple, unadorned options often prevail.

Price breakdowns within this budget category typically fall into three tiers. The lower end (£10-£15) offers basic polyester or vinyl blinds and inexpensive cotton or polyester curtains. Expect limited durability and a shorter lifespan, but they’re perfectly serviceable for renters or those seeking temporary solutions. Mid-range options (£15-£20) introduce fabrics like linen blends or heavier cottons, alongside more robust blind mechanisms – you'll find marginally better quality and a slightly longer expected use. The upper end of the range (£18-£20) might offer enhanced features such as blackout linings or specialist weaves, but often at the expense of overall value.

A common mistake among UK buyers is focusing solely on price without considering fabric performance. Cheap polyester curtains will fade dramatically in direct sunlight and may attract dust excessively. Similarly, flimsy blinds are prone to warping or breaking with even moderate use. Another pitfall is neglecting measurements; installing blinds that are too small or curtains that are too short is a frequently encountered frustration. Accurate window dimensions – including any architectural quirks like sills or protruding brickwork – are absolutely vital for achieving a professional look.

Furthermore, many buyers overlook the importance of light control. While sheer fabrics offer beautiful diffused light, they often fail to block out significant sunlight. Investing in a blind with adjustable slats provides superior glare reduction and privacy. Similarly, curtains that don’t fully cover the window frame will let in drafts and reduce insulation effectiveness, particularly during winter months.

Finally, it's worth noting the prevalence of ‘sale’ pricing within this category. Many retailers heavily discount end-of-season stock; however, be wary of purchasing items with visible damage or compromised materials simply because they're on offer. A little patience and careful comparison shopping can yield significant savings, but don’t let a low price tempt you into sacrificing quality – the long-term cost of replacing poorly made curtains or blinds will almost certainly outweigh any initial saving.
