FAQ

I've measured my window but the curtains look too small – what am I doing wrong?

Often, people only measure the width of the window recess. You also need to account for the curtain pelmet (the board above the curtain) and ensure there’s enough fabric to allow for fullness when the curtains are drawn fully open; aim for at least 15-20cm extra width per window.

I ordered blinds with a ‘motorised’ option, but it wasn't actually installed – what can I do?

Motorisation is an optional extra that needs to be professionally fitted. Check the product description carefully before ordering to confirm if installation of the motor kit is included or if it's an add-on; Amazon generally lists this clearly.

I bought a set of voile curtains, but they don’t completely cover my window when layered with thicker drapes – how do I fix this?

Voile curtains are designed to be layered over heavier fabrics. Ensure you've selected a curtain rod wide enough to accommodate both layers and consider using a blackout lining for the main drape to achieve full light control.

The online description said ‘ready-made’, but the curtains arrived with loose threads and minor imperfections – what are my options?

‘Ready-made’ doesn't guarantee perfect condition; check the product carefully upon arrival and report any significant damage immediately to Amazon, who will handle returns according to their standard policy.

I’ve ordered blinds for a small room – should I really go for a large, elaborate blind or can I get away with something simpler?

Consider the space's proportions; larger, more decorative blinds can overwhelm a small room. Opt for a slimmer design with minimal detailing to maintain a sense of openness and avoid visually shrinking the space.

The website didn’t mention anything about delivery costs – how much will it actually cost to get my curtains delivered?

Delivery charges vary significantly depending on the retailer, product size, and your location. Always check the final price including postage before completing your purchase; Amazon typically displays this clearly at checkout.

I’m unsure about fitting – can I just hang the blinds myself, or do I need a professional?

Blind installation complexity varies greatly depending on the type. Roller blinds and Venetian blinds are generally straightforward to fit yourself, while specialist blinds like pleated shades may require professional installation for correct operation.

I’ve bought some blackout curtains, but they don't block out enough light – what could be causing this?

Check that the curtain rod is positioned correctly above the window frame to prevent light leakage. Also, ensure you are pulling the curtains fully closed and consider adding a blackout lining for optimal darkness.

I’ve ordered custom-made curtains, but they’re not quite the colour I expected – what can be done?

Custom orders often allow for minor adjustments; contact the manufacturer directly (details should be provided at time of order) to discuss potential colour matching or alterations based on their policy.

I'm worried about curtains fading in direct sunlight – what kind of fabric is best?

Consider a densely woven fabric with a light colour and UV protection. Fabrics like blackout lining or those specifically marketed as ‘fade-resistant’ will help to mitigate this issue, but always follow the manufacturer’s care instructions.

In depth

Measuring for curtains or blinds is consistently the biggest source of frustration for UK homeowners. It’s easy to get it wrong, but the consequences – ill-fitting windows, gaps, and a general feeling that something isn't quite right – are immediately apparent. The most common error is simply failing to take accurate measurements before ordering. Don’t rely solely on an estimate; meticulous measurement is crucial. Start by determining your window’s exact width. Measure across the recess where the blind or curtain will sit, noting any irregularities like sills or protruding hardware. Add at least 5cm – 10cm for a blind and 7.5cm - 12cm for curtains – to allow for mounting brackets and ensure a snug fit. For curtains, you’ll also need to measure the window's height, accounting for the desired fullness of the fabric. A general rule is that curtains should fall approximately halfway between the windowsill and the floor, but this can be adjusted based on personal preference and the style of the room. Don’t forget to factor in any adjacent walls or furniture that might impact the overall dimensions. If you're unsure about complex window shapes – bay windows, for example – consider getting a professional measurement service; it’s a small investment compared to the cost of reordering.

Many shoppers are seduced by technical specifications when choosing blinds, often overlooking what those specs actually mean in a real-world home setting. You might see a ‘motorised blackout blind with child safety tassels’ and assume that's exactly what you need. However, if you only use the blind twice a week, the cost of the motorisation is significantly wasted. Similarly, some blinds boast incredibly dense fabric coatings for maximum light blocking – fantastic in a media room, perhaps, but completely unnecessary (and costly) in a bedroom used primarily for reading. Before committing to a high-specification product, honestly assess your needs. Do you *really* require blackout capabilities? Will you be using the remote control frequently, or are you happy to manually operate it? Consider whether the added features – such as adjustable slats, light filtering options, or integrated sensors – will actually enhance your experience, or simply add to the cost. Prioritize functionality over fancy extras if your budget is tight.

The initial price of a blind or curtain set can be misleading, particularly when considering the extra costs involved in fitting and operation. The listed price rarely includes the mounting hardware, which can vary significantly depending on the type of blind (roller, Venetian, vertical) and the window’s construction. Roller blinds typically require a track bracket, while Venetian blinds need a headrail and pulley system. Vertical blinds often necessitate more complex fixing solutions. Furthermore, motorised blinds almost always come with an additional cost for the remote control and potentially the battery pack or charging unit. Don't forget to factor in any potential electrical work if you’re installing a motor; you might need an electrician to install a dedicated socket. Finally, consider the ongoing running costs of automated blinds – replacement batteries are a recurring expense.

Blind materials often come with confusing terminology that can lead to misinterpretations. ‘Blackout’ doesn't necessarily mean complete darkness; many blinds only reduce light by 80-95%, while others offer significantly less coverage. Similarly, ‘thermal’ blinds aren’t always effective at retaining heat – their thermal performance depends on the fabric density and construction. When researching materials, look for specific details about light transmission rates (measured in ‘lux’) and thermal conductivity values. Don't be swayed by marketing claims; read the manufacturer’s specifications carefully to understand exactly what you’re buying. If you’re concerned about energy efficiency, consider investing in blinds with a proven track record – some fabrics are specifically designed for optimal insulation.

Fabric choices frequently lead to disappointment due to inaccurate expectations of colour and texture. A swatch is essential, but it can only provide a limited representation of the fabric's true appearance under different lighting conditions. Consider the room’s natural light exposure when choosing a colour; dark shades will absorb more light and may appear deeper in a dimly lit room, while lighter colours will reflect light and brighten the space. Similarly, texture plays a crucial role in the overall look and feel of the blind or curtain. A thick, plush fabric might feel luxurious but could also block out too much light, while a sheer fabric offers minimal coverage but creates a delicate, airy effect. Order multiple swatches to test how the colour looks alongside your existing furniture and décor before making a final decision.

Finally, don’t be overly influenced by trends or ‘headline specs’ that seem impressive at first glance. A blind boasting “revolutionary light control” might have a complex mechanism that's difficult to operate and prone to malfunction. Similarly, curtains marketed as "premium velvet" may feel cheap and uncomfortable against the skin. Focus on functionality, durability, and suitability for your specific needs rather than chasing fleeting trends or over-engineered features. Read customer reviews – but take them with a pinch of salt; individual experiences vary significantly. Ultimately, choosing curtains or blinds is an investment in your home’s comfort and style, so prioritise quality and practicality above all else.
