Finally, curtains that actually transform a room
I'd been putting this off for months, convinced I'd have to go bespoke to get this quality. The weight of the fabric when you open the box — you know immediately you've made the right choice. My bedroom finally looks the way I always wanted it to.

The drape is everything
I've ordered from John Lewis, I've tried M&S. Nothing has ever fallen like this. Floor to ceiling, not a wrinkle, not a sag. My sitting room looks completely different and my husband, who questioned every penny, hasn't said a word since.

Delivery took a little longer than expected but the curtains are exceptional
Delivery ran a few days behind the estimated window, which was slightly frustrating. That said, the team kept me informed throughout and the curtains themselves are genuinely stunning. The quality more than makes up for it I'd order again without hesitation.

Worth every single penny
I was hesitant at the price point but the moment I hung them I understood. This is what quality actually feels like. I've already recommended THE ATELIERS to three friends and I'll be ordering for the dining room next month.

Pitch black at noon, genuinely life-changing
I have a south-facing bedroom that has always been impossible in summer. I've tried every blackout solution on the market. These are the first that actually work and they look stunning doing it.

My heating bills have actually dropped
Ordered in October and by December I noticed a real difference. Less draught, warmer rooms, less reliance on the radiators. The thermal performance is genuine — not marketing. Beautiful curtains with real substance behind them.

SMART INSULATION MEETS TOTAL DARKNESS
Master your sleep and climate. Our advanced curtains block 100% of light while keeping your home warm in winter and cool in summer.
THE ATELIERS — Got questions?
Everything You Need to Know
Honest answer: no curtain achieves total darkness — and we would rather tell you that than overpromise. What our triple-weave construction does achieve is blocking the vast majority of incoming light — enough to turn a bright summer morning into a restful, sleep-ready room.
For best results, choose a pole that extends 15cm beyond each side of the window and hang as close to the ceiling as possible.
Many customers tell us their bedroom has never been darker.
They do — and we want to be precise about how. Our multi-layer insulating lining acts as a barrier between the cold glass of your window and the warmth of your room, reducing draughts and heat loss.
They won't replace your heating, but they will help it work less hard — a difference you notice most in older properties and during the coldest months.
A real improvement in comfort — without the inflated claims.
As a general guide, your curtains should be 2 to 2.5 times the width of your window for a full, luxurious drape. For length, we always recommend floor to ceiling — the most elegant result, and the best blackout and thermal performance.
THE ATELIERS offers all standard UK sizes, and our detailed Size Guide walks you through every measurement step by step.
Still unsure? Our customer team is available 6 days a week to help you find the perfect fit.
We photograph all THE ATELIERS curtains in natural daylight to ensure the colours you see are as accurate as possible.
However, as screens vary, we recommend ordering a fabric sample before committing to a full order — it's the best way to see the true colour, weight and texture in your own home.
Our samples are available for a small fee, redeemable against your purchase.
All THE ATELIERS orders are dispatched within 24 to 48 working hours and delivered within 6 to 9 working days across the UK.
You will receive a tracking number by email as soon as your order is on its way, so you can follow your delivery in real time.
Free delivery on all UK orders — no minimum spend required.
We completely understand — choosing curtains online isn't always straightforward. That's why THE ATELIERS offers a 30-day hassle-free return policy. If you're not completely satisfied, simply contact us and we will arrange a collection at no extra cost.
We want you to love your curtains — and if for any reason you don't, we'll make it right.
No forms, no fuss — just honest service.
