What size duct is it? 54mm possibly?

Looking at the other houses on the street they all seem to be 54mm

Normally a BT Duct 56 (54mm) on an outside wall would typical be fitted with a 'Duct Plug 1A' which is simply high density sponge but that doesn't stop water and gas ingress as its not a problem being outside. If you have a duct coming up inside your property you would need to use either a Filoform duct sealant or maybe Openreach have a different seal to seal it up when inside.

If you're prepared to lift the carpet and uncover the duct you will have a better idea of what you need to do but as that previously outside wall now has plasterboard on it there is a high chance the duct will partly be cover by that plasterboad. it all depends on how risk adverse you are.

If your lucky they may have just cut it level with the new floor and there is a gaping hole just underneath the surface

Unfortunately the floor has been screeded over to raise it up to a similar level to the interal floor so there is no hole underneath . I can tell they've done it themselves as there's a dogs paw print in the screed and it's not what you'd call level.

I agree Dect that part of the original duct will have been underneath the plasterboard as it would have sit flush with the brickwork. I fitted (well paid for lol) the skirting but whilst it was off I couldn't see any evidence of the duct.

I wish now that i'd have knocked some plasterboard off and given the floor a whack to properly check however for some reason I was thinking the house was direct burried, but after checking every other house on the street has ducting so I doubt this one was any different.

Did you see any evidence of the telephone cable on that wall?

I don't think I actually checked. At the time I bought the house it was an exchange only line so (in hindsight not ideal) didn't really check much as was planning and preparing house for Virgin Media.

I think I'll knock a little of the skirting off and cut a small incision in to the plasterboard and see whats there. Hopefully I do this without piercing the copper.
