What we like
  • Set of two offers excellent value for money

  • Aesthetically pleasing

  • Keeps cold air out

  • Can be hooked to your doors for maximum efficiency 

What we don't like
  • The covers aren't removable which may make them a bit tricky to keep clean

Key specs

Our verdict

When you're all snuggled up under your best heated throw or blanket hoodie, the last thing you want is to feel the chill of an icy draught. Thankfully, these weighted fabric Nicola Spring Door Draught Excluders are an easy way to prevent cold air from creeping in under your internal doors. We love the handy hooks on each draught excluder, allowing you to attach them to your door so you don't have to move them every time you leave the room.

The classic herringbone pattern, dark grey colour and sweet white hearts offer a lovely country cottage charm. Sold as a pair and with a two-year warranty included, they also offer excellent value for money.


Best budget draught excluder

EXTSUD Adhesive Strip Draught Stopper

What we like
  • Cost-effective

  • Easy to install

  • Provides sound insulation 

What we don't like
  • Not the most attractive option

  • Won't stick as well on external doors

Key specs

RRP: £8 | Material: Non-toxic silicone | Dimensions: 100 x 5 x 0.5cm (in the form of a strip) | Machine washable: N/A 

Our verdict

If you have a lot of doors requiring draught prevention, even the cheapest of fabric excluders could prove costly. These adhesive strips from EXTSUD come with hundreds of five-star reviews and it’s easy to see why. A cost-effective way to draught-proof several doors in your home, these pre-glued strips can be installed in next to no time without the need for tools. The clever three-layer design will not only keep out the cold but can also help to reduce sound up to five times.

Some reviewers did note that the strips did not hold on garage or external doors though, so it’s best to keep them for indoor use.

Best draught excluder for front doors

Stormguard Door Brush Strip Draught Excluder

What we like
  • Works on most doors

  • Cost-effective

  • Good for external doors

What we don't like
  • You’ll need to screw it to the door - the fixings are concealed though

  • It may need trimming down to size

Key specs

RRP: £11 | Material: Polyvinyl chloride | Dimensions:‎ ‎86.5 x 5 x 1cm (can be cut to size) | Machine washable: N/A

What Mumsnet users say
PausingFlatly · Recommended brand
"Have a look at the Stormguard website for lots of draught-proofing products you may not have thought of."
See Post

Our verdict

This Stormguard Draught Excluder is a great option for your front door, garage door or sliding doors. It won’t succumb to the elements and can attach securely to successfully keep underfloor draughts at bay. With a compact row of bristles, the brush seal traps air without dragging or causing damage to your carpets.

It’s worth noting that you will need to screw this to your door, although the screw heads will be concealed once installation is complete. Although it does come in different sizes, you may also need to cut it down to size – so be prepared to get your tool kit out.

Best double-sided draught excluder

Fowong Under Door Draught Excluder

What we like
  • Uses elastic bands and hook and loop tape to help it fit better

  • Machine washable

  • Also guards against noise, light, wind and dust

What we don't like
  • May need to be cut to size

  • Risk that fitting tab could stop doors from closing

Key specs

RRP: £23 | Material: Fabric not specified | Dimensions:‎ 88 x 5cm; 98 x 5cm; 108 x 5cm (and can be cut to fit) | Machine washable: Yes (removable cover)

Our verdict

We love the convenience of this double-sided draught excluder. Not only will it prevent draughts (as well as noise, dust, light and insects) from sneaking under your doors, but it is easy to fit and is machine washable too. Fowong claims to be the only manufacturer to use their 'hook and loop' design which prevents the draught excluder from moving around. However, some reviewers said this also stopped doors from closing properly.

Each pack comes with six rolls of white foam tubing, which can be cut to size to fit most doors. They’re fairly discreet too and available in a choice of grey or black - perfect for using alongside the best thermal curtains to keep your home warm and insulated.


Best draught excluder for floorboards

StopGap Floorboard Draught Excluder

What we like
  • A highly effective way of making homes with wood floors warmer

  • No mess installation 

What we don't like
  • A little on the pricey side

  • Not as easy to use with larger gaps

Key specs

RRP: £25 | Material: StopGap material | Dimensions: 19 x 18.01 x 2.01cm | Machine washable: N/A

What Mumsnet users say
LittleLongDog · Tried & tested
“There’s a StopGap thing you can buy to put in between floorboards. I did mine and it worked really well.”
See Post

Our verdict

If you’ve got exposed wooden floors in your home, gaps in the floorboards can allow draughts to rise up between them, as well as risk losing valuable warm air from your central heating underneath the house.

The StopGap Draught Excluder is easy to install. Simply unroll the V-shaped plastic and push it down into the gaps in your floorboards using a credit card. If the gaps are narrow, the plastic should just hold itself in place whilst remaining virtually invisible. However, for larger gaps, you may also need to use some silicone, which will take a little longer and may make them more visible. Whilst nearly all customers agreed that the tape certainly made their rooms warmer, some did feel that it was a little pricey for what is essentially a simple roll of plastic.


Best foam tape draught excluder

What we like
  • Mess-free installation

  • Discreet and non-visible once fitted

What we don't like
  • A little time-consuming to install 

Key specs

RRP: £31 | Material: DraughtEx | Dimensions: 40-metre roll with 8mm width | Machine washable: N/A 

What Mumsnet users say
Loulouscandi · Recommended
“We used this which you wedge between every floorboard. It took quite a while, but it did make much more of a difference than I thought it would.”
See Post

Our verdict

The DraughtEx Roll foam is an excellent, mess-free way to block up small and narrow gaps such as those found between floorboards and skirting boards. It requires no adhesive, but you will need to trim it down to size and add it between all the gaps and cracks, which some reviewers found a little time-consuming. 

Cleverly designed to mimic the natural shadows created between the gaps, once fitted, it’s non-visible and won't spoil the aesthetic of your room. It also comes in a thinner 4mm version too, making it easy to find the right fit for your home.

Best fabric draught excluder

John Lewis Stripe Draught Excluder

What we like
  • A simple and effective way to keep out draughts

  • Will bring a stylishly cosy feel to your room

  • Neutral design ideal for living spaces

What we don't like
  • Spot clean only

Key specs

RRP: £28 | Material: Outer 100% cotton, lining 100% polypropylene, filling 100% polyester, leather strap | Dimensions: 100 x 13 x 8.5cm | Machine washable: No, spot clean only 

Our verdict

When you've just got in and shrugged off your heated gilet, the last thing you want is to have to sit in a chilly room. This hard-wearing fabric design from John Lewis will not only keep out the draughts under your internal doors, but it also offers a neutral and modern look that won’t look out of place in a stylish living space. 

Sturdy enough to stay put against the door, but light enough to be moved with ease, we love the integrated leather strap to aid portability. The only downside? It’s spot clean only and as such, the lighter colour of this design may be a little challenging to keep clean.


Best draught excluder for chimneys

Chimney Sheep Chimney Draught Excluder

What we like
  • Made from natural products

  • Is likely to affect your heating bill

  • Minimises wind noise from the chimney 

What we don't like
  • This isn’t a one-size-fits-all product, so you’ll need to measure the inside of your chimney

Key specs

RRP: From £27 (depends on size) | Material: Wool | Dimensions: 14 x 36 inches (comes in a variety of sizes to fit different chimneys) | Machine washable: Yes

What Mumsnet users say
Wingedharpy · Vetted
“I am the proud owner of two Chimney Sheeps. It made a huge difference in my draughty, old terraced house.”
See Post

Our verdict

A wood burner or real fire is a lovely addition to any room. However, when it’s not in use, your chimney is likely to be the single biggest source of warm air loss in your home, with experts calculating that a chimney draught excluder can save you up to £65 per year.

The popular Chimney Sheep is a removable chimney draught excluder made from naturally breathable wool. It also comes with a handle for easy removal if you use your fire regularly. As a bonus, a Chimney Sheep will also reduce wind noise and prevent debris from falling down your chimney.

For the Chimney Sheep to work properly, it must fit snuggly, so you'll need to measure the inside of your chimney breast correctly, which is something that some felt was a little challenging.


Best letterbox draught excluder

What we like
  • Will reduce noise as well as draughts

  • Available in different colours

  • Easy to install 

What we don't like
  • Pricey

Key specs

RRP: £33 | Material: ABS and galvanised steel | Dimensions: ‎Internal aperture: 290 x 70mm; external size: 340 x 98mm | Machine washable: N/A

Our verdict

If you live in a property without a hallway, you could experience a significant draught coming from your letterbox, bringing cold air right into your front room. The Magflap Letterbox Draught Excluder can keep out the cold and reduce noise, while the magnets allow your postie to still deliver your mail with ease. 

Although it does require screws, just about every reviewer reported that it was simple to install. The Magflap is a little pricier than some letterbox draught excluders but comes with far more positive reviews than the cheaper alternatives.

Best draught excluder for windows

Stormguard Window and Door Gasket Seal

What we like
  • Cost-effective

  • Keeps out cold air around windows

  • Universal seal suitable for doors and windows 

What we don't like
  • Could be a little tricky to install

Key specs

RRP: £8 | Material: UPVC rubber | Dimensions: Available in 6, 12 and 20m | Machine washable: N/A 

What Mumsnet users say
Plexie · Tried & tested
“Have a look at Stormguard seals and draught excluders. They have a wide variety of types/shapes and they're longer-lasting than the very cheap foam strips.”
See Post

Our verdict

Although double glazing and UPVC window seals are a great way to draught-proof your home, seals can become compressed or wear away over time, reducing their effectiveness at keeping out the cold.

The Stormguard Window and Door Gasket Seal requires no adhesive, you simply push it into the channel or groove inside the frame. Whilst this certainly makes installation mess-free, some reviewers found it was a little fiddly, particularly around the corners. That said, it's worth the effort as it's super effective, so you can snuggle up in the best women's dressing gown without having to worry about cold air leaking in.


Best novelty draught excluder

Dora Designs Pepe Senior Draught Excluder

What we like
  • Guaranteed to put a smile on your face

  • Well made and highly effective

  • A cute addition for families 

What we don't like
  • May be a little cumbersome for some

  • It’s a lot of money to pay for a single draught excluder

Key specs

RRP: £40 | Materials: Boucle fabric with polyfibre and wadding | Size: 14 x 84cm | Machine washable: No, sponge clean only 

Our verdict

This delightful draught excluder by Dora Designs comes with a host of incredibly positive reviews, which is no surprise given that it's in the form of an adorably grumpy cat – what’s not to love?

Reviewers were keen to note that, despite its novelty design, this draught excluder was incredibly well made with high-quality fabric that is very effective at keeping out the cold. 

It’s a little heavier than most fabric draught excluders, so while it can double up as a handy door stop, it does have the potential to get in the way if you're opening and closing the door regularly.

What to look for in a good draught excluder 

The right draught excluder for you will depend on your needs - specifically the source of your draught and the type of heat loss you are experiencing. Here are some things to consider when making your choice:

  • Size - Does the draught excluder come in pre-set sizes? If so, you must learn the exact dimensions of the space you’re trying to insulate - whether that's a window, door or gaps between your floorboards. Some draught excluders come in longer lengths that can be cut to size, but it's important to measure carefully to ensure a perfect fit.

  • Assembly - How easy is the draught excluder to fit? Does it require any tools or screws? Some draught excluders are physically placed over the source of the draught to simply block airflow, whilst others need to be physically attached and installed. You may wish to consider the time taken to install and weigh this up against the benefits.

  • Aesthetic - Some draught excluders are more noticeable than others. In a modern home, you may wish to opt for discreet or non-visible draught excluders (such as those that go between the gaps of your floorboards). Alternatively, you may wish to choose fabric draught excluders that, although noticeable, can actually add to the overall look and feel of your room, similar to curtains and cushions. If you’re using more noticeable under-door brushes, you may prefer to stick to external doors only. 

  • Portability - Does the draught excluder remain permanently installed once fitted, or does this need to be removed e.g. chimney or fabric door draught excluders? If portable, how easy is it to move around and is it likely to become cumbersome when moving around inside the home? 

  • Cost - How much are you willing to spend and how does this compare to the money you can save as a result?

What are the different types of draught excluders? 

  • Under door brush draught excluders - Most commonly used on external or garage doors, this style of draught excluder is normally screwed to the door and blocks air flow between the base of the door and the frame. 

  • Foam or rubber draught excluders - Ideal for sealing gaps between windows, doors and floorboards, these foam or rubber strips are easy to install, even in small gaps, to prevent warm air from escaping or cool air from creeping in. 

  • Chimney draught excluder - These large draught excluders are used to insulate your chimney breast when your fire is not in use, effectively sealing a large source of heat loss whilst reducing audible wind noise too. 

  • Letterbox draught excluder - These are fitted inside your letter box to prevent draughts whilst maintaining relatively easy access for your postie. 

  • Fabric draught excluder - Usually long and chunky tubes placed in front of the door when you're settling down in a room. They prevent air loss from underneath the door frame and tend to come in attractive designs. However, they may need moving to open and close the door.

  • Strip draught excluder - Possibly the cheapest option, these adhesive strips can be added to the bottom of doors and windows to create a physical barrier for air and prevent heat loss. They aren’t the most aesthetically pleasing and they tend to wear off over time, but make a popular choice if you want quick results on a budget. 

What is the best way to stop draughts around doors?

A well-fitting draught excluder is the easiest and cheapest way to stop draughts coming through your doors.

You could also hang a pair of thermal curtains, which will make a big difference,  particularly if your front door opens straight into your living area. Cold may also come in through gaps around the edges of your door so you may need to fill them with foam or a seal, or also consider purchasing a letterbox draught excluder too. Finally, if you really want to go all out, you can get a keyhole cover such as this STORMGUARD one. These are metal discs designed to drop over the hole and keep out the cold.

When draught-proofing your home, remember that you do need to maintain ventilation in each room otherwise you’ll be prone to mould and damp. To allow fresh air to circulate, make sure you never block up spaces that are specifically designed to let the outside air in such as airbricks, underfloor grills, or vents.

How to fit a draught excluder around a door

This will largely depend on the type of draught excluder you’re using. Fabric excluders don’t require any fitting unless you want to hook it to your door, in which case you’ll need to hammer in a couple of nails to attach it. Some of the strip options come pre-glued, whilst others will need screwing onto the door.

Can you paint over your draught excluder?

If you’re fitting a strip draught excluder that uses adhesive or is screwed to your door, you may be able to paint it, particularly if it is made of wood. However, when it comes to seals, you won’t be able to paint them as the paint will prevent the seal from expanding and filling the gaps, rendering it ineffective. It's always best to choose a seal that is closest in colour to your windows and doors, so you don't have to paint it.
