I get weatherstripping from a few places but Mighton seem to have a good selection.

You need to measure the groove and the gaps obviously but it should be pretty obvious what the options are once you've measured. If possible I like to use a seal that has some acoustic properties as well as draught sealing.
Just to add, I've never found one in small quantities from the big box depots that lasts. I usually buy a quantity of the expensive stuff and then I'm fitting it to different places for a few years. My go to for that purpose has been the corner type which wouldn't work because you have the groove.

The wide and shallow slot looks like it has been cut for a seal carrier and brush pile.
Brush is available in different height pile and base width, but here's an option

Door seal question. Don't have one, would like one to stop draughts. It's a timber frame with a groove which I presume is for a seal. Can anyone what style of seal to go for here?
Cheers
