Draught excluders might not be glamorous, but they’re one of the easiest ways to cut heating costs and keep your home cosy. Whether you live in a draughty Victorian terrace or a modern flat with cold laminate floors, blocking under-door breezes can make a noticeable difference. And the best part? You don’t need to spend more than £20 to get one that works — and looks good doing it.
This roundup focuses on Amazon UK’s top-rated draught excluders under £20, with a cheeky tone and practical advice. We’ve included a budget breakdown, icon-based product list, energy-saving tips, and real user reviews to help you pick the perfect stopper.
💸 Budget Breakdown: What You Get for Under £20
Here’s what your budget buys you:
- Under £10: Foam rolls, twin-door sliders, and basic fabric tubes — functional but not fancy
- £10–£15: Faux fur, washable covers, and soft-touch velour options — stylish and practical
- £15–£20: Weighted velvet, extra-long stoppers, and premium finishes — ideal for patio doors or wide gaps
Most options are 90cm long, filled with polyester or hollowfibre, and designed to sit flush against the door. Some are decorative, others are purely functional — but all help keep the chill out.

🧠 Energy Tip of the Week: Why These Work So Well
A good draught excluder can reduce heat loss by up to 15% in rooms with external doors. That’s £25–£50/year saved on heating — not bad for a tenner. Cold air sneaks in under doors, especially in older homes, and your boiler works overtime to compensate. By blocking that breeze, you keep warm air inside longer and reduce the need for constant heating.
Pair your draught excluder with thermal curtains, radiator reflectors, and door seals for a full winter-proof setup. Bonus: many of these products qualify for energy-saving grants or discounts in the UK.

🧵 Why Every UK Home Needs One
Draught excluders aren’t just for aesthetics — they’re a practical, low-cost way to improve comfort and reduce your carbon footprint. In UK homes, especially those with older doors or laminate flooring, under-door gaps are a major source of heat loss. A simple fabric tube or foam strip can block that cold air instantly.
They’re also incredibly easy to install. Most fabric excluders just sit in place, while under-door sliders and adhesive strips take less than five minutes to fit. No tools, no drilling, no DIY disasters. And because they’re portable, you can move them from room to room as needed — or even take them with you when you move.
Beyond function, they’ve come a long way in style. You’ll find options in velvet, faux fur, tweed, and even novelty shapes (think sausage dogs and foxes). Some are weighted to stay put, others have washable covers, and many are available in colours that match your decor. Whether you’re in a rental, a flat, or a draughty Victorian terrace, there’s a budget-friendly option that works.
🏁 Final Verdict: Cheap, Cheerful, and Surprisingly Effective
You don’t need to spend a fortune to stay warm. These draught excluders under £20 actually work, look great, and help cut your heating bills. Whether you want plush, practical, or pet-approved, there’s a stopper here for every door and every budget — all delivered straight from Amazon.
