Fantastic draft excluder
So easy to use just screw the handle\stick in, I also ordered the extender stick so the tag is clearly visible in the chimney to avoid anyone turning on the fire while still in place, easy to insert just push into the chimney gap and it’s done, you do need to check what size as the chimney sheep needs to be slightly bigger so it wedges in place. It’s working a treat no drafts and also stops the heat escaping. I have turned the heating down 1.5 degrees and even during the recent extreme cold weather I haven’t needed to turn the heating back up bonus. This will definitely pay for itself in no time and then some. Very very pleased only wish I’d bought it sooner.

Plug the gap
I live in a 1950s box. You know the kind. They all used to have back boilers in the chimneys and over the years home owners have taken them out and installed combi boilers elsewhere in the house. This leaves the open fireplace which one could choose to brick up, to cover with an electric fire and surround, or to leave open as a 'feature' of some sort in the living room. The other legacy of the back boiler is that somewhere in the living room there will be a not-insignificantly sized gas vent in the wall, which undoubtedly pulls in a draft which would register on the Beaufort scale. Now - you can have draft excluders under every door, you can install a cowl on the external wall to prevent the gale blowing straight in, you can install a hit-and-miss vent on the internal wall, but mark my words - you will still get the chilliest draft blowing into your living room which maintains the temperature at a constant 3 degrees below the rest of the house and makes a blanket a necessity when watching the telly in the evenings. Finally. FINALLY. After 7 years I worked out that the draft being pulled into the room from the vent, was largely down to the fact that the electric fire I had chosen to install in the 'hole' that the back boiler had left had two vents underneath it. Behind the electric fire was the chimney cavity and up the chimney a little way was the corrugated metal chimney flue....which had not been blocked off. The cold outside air was subsequently being sucked from outside, through the wall vent, and up the chimney flue, taking all of the heat from the room with it. I could also hear rain loudly bouncing off the chimney cap, and pigeons sitting up there coo-ing to one another, all acoustically amplified down the flue and into the living room. I knew I had to cap the flue from the living room end, but how? I was concerned about causing damp, and I didn't want to restrict the air exchanges in the house. After a bit of research, I happened upon the Chimney Sheep, which was the answer to everything! Ridiculously simple design, it's essentially a woollen plug, which has enough give for you to twist and manipulate into the chimney vent, blocking the draft but allowing air to move through it (so no problems with air circulation or damp). It has a handle on it, so should you have an open fire grate you can simply remove it when you light a fire, and replace it afterwards. I seriously cannot express the difference it has made in my previously Siberian front room, which is now positively cosy. I can only imagine the effect it's having on my energy useage - and as a plus...I can't hear the pigeons in surround sound anymore!

Great idea but....
This was exactly what I am needing to block an 8in flue. Easy to fit and remove but due to the design of my chimney the flue aperture is 1.2m above the fireplace. I assumed I would get around this by using a universal chimney/drain rod which would extend the handle. Unfortunately the thread on the excluder does not fit the rod which meant i could not fit it my chimney. There are extentions available for the handle but the number i need would double the cost. But if your flue is within arms reach then it will do as it says on the tin.

Simple but effective
I was really impressed with this. I had a problem when windy with soot coming down the chimney flue and on the laminate floor. This stops all the soot, stops draughts and keeps the room more insulated and warmer when using the central heating. Simple but effective

Good but wrong measures
Good idea but the recommended measures does not feet. Buy a little bigger from their recommendations. If you have the correct size it is doing the job very well.

I'm thrilled with my order.
I'm thrilled with my order. Winter is coming, and storms are coming. I live by the sea in a 130-year-old house. I was looking for something that would help limit cold air during the winter season. This is fantastic. The change is huge as soon as I put it in its intended location. The sound from the chimney is significantly reduced. Finally, I'm no longer disturbed by the sound of seagulls sitting on the roof next to the chimney, nor by the sound of the wind. A great purchase.
