A draught excluder is a cheap and effective way of saving money on heating bills by keeping the cold air out and the warm air in. Here's our pick of the best to keep your home cosy this year.

Draught excluder on door

There’s nothing worse than a draughty room once the cold weather hits, and with the cost of energy bills on the rise, it’s more important than ever to preserve warmth and keep heating costs down as much as possible. With recent news that the energy price cap will rise by 80% from 1st October, and predictions that most people will pay around £1,570 more per year for gas and electricity, many are preparing for a significant increase in bills this winter.

Every family should have the right to a warm home, and if this is something that you feel you need advice or support with, there are various bodies and organisations that may be able to help. There are also small things that you can do to conserve heat during the colder months, and a properly fitted draught excluder is a relatively cheap yet effective way to minimise heat loss.

Gone are the days of simply whacking up the central heating to get rid of the cold as we’re all so much more aware of the money we’re spending on heating our homes. When you do turn on your heating, the last thing you need is for all that warmth to escape. 

You’ve potentially already thought about draught excluders for your internal doors, but cold air can get in from chimneys, windows and even gaps in your floorboards. So, we’ve done the research for you, collating the best draught excluders for all areas of the home which will hopefully help keep you and your family that little bit warmer whilst saving money on fuel bills.

Here are the best draught excluders to buy in 2022.

1. Best overall draught excluder: Nicola Spring Herringbone Fabric Draught Excluder

Nicola Spring draught excluder

Price: £19.99 for two | Buy now from Amazon

These weighted fabric draught excluders are an easy way to prevent cold air from creeping in under your internal doors.  

The classic herringbone pattern and dark grey colour offer a lovely country cottage charm. We love the handy hooks on each draught excluder too – you can attach them to your door so you won't have to move them every time you leave the room. 

And, at just under £20 for two, plus a two-year warranty, these are also excellent value for money. 

Pros

  • Good value for money
  • Aesthetically pleasing
  • Keeps cold air out

Cons

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

2. Best budget draught excluder: EXTSUD Adhesive Strip Draught Stopper

Adhesive draught stopper

Price: £7.99 | Buy now from Amazon

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. They provide a cost-effective way to draught-proof a number of doors in your home and, as they’re pre-glued, you’ll be able to install them in minimal 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.

Pros

  • Cost-effective
  • Easy to install

Cons

  • Not the most attractive option
  • Won't stick as well on external doors

3. Best foam draught excluder: DraughtEx Roll 8mm Width

DraughtEx roll

Price: £31.40 | Buy now from Amazon

“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”. (Tried and tested by Mumsnet user Loulouscandi)

This 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 fit it between all small gaps and cracks which some reviewers found a little time-consuming.

The DraughtEx foam is cleverly designed to mimic the natural shadows created between the gaps too, so once it’s fitted you shouldn’t be able to tell it’s there and it won't spoil the look of your room. It also comes in two additional widths – 4mm and a thicker version for gaps between 6 to 11mm – making it easier to find the right fit for your home.

Pros

  • Mess-free installation
  • You can’t see it once it’s fitted

Cons

  • A little time consuming

4. Best fabric draught excluder: Dunelm Teddy Bear Draught Excluder

Dunelm draught excluder

Price: £12 | Buy now from Dunelm

This super-soft fabric design from Dunelm will not only keep out the draughts, but it will also provide a cosy look with its fluffy, textured fabric.

It's sturdy enough to stay put against the door, but it's light enough to be moved with ease and comes in two lovely colours, making it suitable for any room.

Pros

  • A simple and effective way to keep out the draught
  • Will bring a lovely cosy feel to your room

Cons

  • Sponge clean only 
  • Not as long as some draught excluders

5. Best draught excluder for external doors: Stormguard Door Brush Strip Draught Excluder

Stormguard draught excluder

Price: £9.29 | Buy now from Amazon

This draught excluder is a great option for your front or garage door as it can be attached securely and won’t succumb to the elements. 

The bristles prevent it from dragging and causing damage to your carpets and it’s also a good option if you have sliding doors.

This Stormguard draught excluder will need screwing to your door and, although it does come in different sizes, you won’t necessarily get something that fits your door exactly. If this is the case, you’ll need to cut it down to size – so be prepared to get your tool kit out.

Pros

  • Works on most doors
  • Cost-effective

Cons

  • You’ll need to screw it to the door
  • It may need trimming down to size

6. Best draught excluder for floorboards: StopGap Floorboard Draught Excluder

StopGap roll

Price: £24.99 | Buy now from Amazon

“There’s a StopGap thing you can buy to put in between floorboards. I did mine and it worked really well.” (Recommended by Mumsnet user LittleLongDog)

If you’ve got exposed wooden floors in your home, the chances are there’ll be a draught rising up between the gaps in the floorboards whilst letting the warm air from your heating disappear under the house.

To install the StopGap Draught Excluder, you simply unroll the V-shaped plastic and push it down into the gaps in your floorboards with a credit card. If the gaps are narrower, the plastic should just hold itself in place whilst remaining virtually invisible. However, for larger gaps, you’ll need to use some silicone, which will take a little longer to install and may also make them a little 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.

Pros

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

Cons

  • A little on the pricey side
  • Not as easy to use with larger gaps

7. Best draught excluder for chimneys: Chimney Sheep Chimney Draught Excluder

Chimney Sheep

Price: £42 | Buy now from Amazon

“I am the proud owner of two Chimney Sheeps. It made a huge difference in my draughty, old terraced house.” (Recommended by Mumsnet user Wingedharpy)

“I've had Chimney Sheep in two pre-1900 houses now and they've been great. They keep the draughts out but also allow the bricks to breathe.” (Vetted by Mumsnet user Allineedisyourlovetonight)

A wood burner or real fire is a lovely addition to any room, not to mention potentially cost saving. However, when it’s not in use, your chimney is likely to be the single biggest source of warm air loss in your home, and experts calculate 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 natural wool. As wool is a naturally breathable material, unlike other chimney draught excluders, the Chimney Sheep doesn’t require a gap to allow for ventilation, making it far more effective at keeping the cold out. It also comes with a handle for easy removal if you use your fire regularly.

As an added 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’s vital that it fits snuggly, so you'll need to measure the inside of your chimney breast correctly which is something that some felt was a little challenging.

Pros

  • Made from natural products
  • Is likely to have an effect on your heating bill

Cons

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

8. Best letterbox draught excluder: Magflap MK2 Door Weatherproofing Energy Seal

Magflap seal

Price: £29.90 | Buy now from Amazon

If you live in a property without a hallway, you could have a significant draught coming from your letterbox, straight into your front room. A letterbox draught excluder won’t only keep out the cold but will also help reduce noise and stop the flap from banging against the door in the wind.

The Magflap uses magnets so your postie will still be able to easily get your post through, and 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 many consumers who had tried cheaper alternatives noted that this particular model was by far the most effective, so it may be worth paying that little bit more to keep your home warmer in the long run.

Pros

  • Will reduce noise as well as draughts

Cons

  • A little on the pricey side

9. Best draught excluder for windows: Stormguard Window and Door Gasket Seal

Stormguard window seal

Price: £9.99 | Buy now from Amazon

Although double glazing and UPVC window seals are a great way to draught-proof your home, through time seals can become compressed or wear away, making them less effective at keeping out the cold.

The Stormguard seal doesn't require adhesive, rather you push it into the channel or groove in the frame. Whilst this is certainly mess-free, some reviewers did note that it was a little fiddly to install, particularly around corners.

Pros

  • Cost-effective
  • Keeps out cold air around windows

Cons

  • Could be a little tricky to install

10. Best novelty draught excluder: Dora Designs Schnauzer Draught Excluder

Price: £39.99 | Buy now from Amazon

This delightful draught excluder came with a host of incredibly positive reviews, which is no surprise given that it's in the form of an adorable Schnauzer – what’s not to like?

Reviewers were keen to note, however, that despite its novelty design, the draught excluder was incredibly well made with good quality fabric and was highly effective when it came to keeping out the cold.

This is a little heavier than most fabric draught excluders. Some did like the fact it was weightier, as not only did it mean the draught excluder lay snug against the door, it could also double up as a handy door stop. However, if you’re going to put it in front of a door that you’ll be opening and closing a lot, it could get in the way a little.

Pros

  • Guaranteed to put a smile on your face
  • Well made and highly effective

Cons

  • Maybe a little cumbersome for some
  • It’s a lot of money to pay for a single door stop

Where to buy a draught excluder

Draught excluders, particularly fabric ones, are readily available in most homeware shops and even supermarkets. However, for the largest selection and options for chimneys, windows and even letterboxes, we found that Amazon offered the greatest choice.

How do I stop draughts coming through my doors?

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

You could also hang a heavy or thermal curtain, 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 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. 

Can you paint over the draught excluder to match it with your door and home?

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 filing 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. 

How much are draught excluders?

Most fabric excluders are around £10 to £20. However, it is possible to draught-proof your home with cheaper alternatives such as plastic strips with adhesive (see our best budget option). Strips with attached bristles are also a cost-effective way to draught-proof lots of doors.

If you’re really on a budget, you could even have a go at making your own. Simply cut the leg off an old pair of trousers, stuff it with filling and sew up the ends or seal with fabric glue.

How to fit a draught excluder around a door

This will largely depend on the type of draught excluder you’re using. Obviously, the 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 some will need screwing onto the door. 

What is the best draught excluder?

If you only need to draught-proof a couple of doors, we love the Nicola Spring Herringbone Fabric Draught Excluder. Not only is it a great way of keeping the cold out, but it looks stylish too. 

Experts say that chimneys are one of the biggest causes of draughts in your home. The Chimney Sheep was recommended by many who have purchased it and is a great way of saving money on your bills.
