No they are not - perhaps you should read the Building Regs?
Ah, the "random stranger" speaks at random?
I'm sure that you mean well but its best to stick to DIY issues,
& leave the Cretan Paradox to others.
FWIW: please understand that the UK Building Regs apply in the UK.

Poster #20,
Why not read what I said, & what the OP said - read very carefully & you will then understand what was said, & what it meant?

OMG, I agree with ree!
Typically, where there is a concrete floor, the DPC would be level with the top of the floor.
In some cases, a cavity tray arrangement can mean a DPC is higher or lower.
Where there is a timber floor, the DPC is commonly a course or more lower than the floor surface - common in older properties.

FFL (not internal DPC) is mostly around the height of the ext DPC, was the point being made, which in most cases it is.
In which case... the FFL is irrelevant anyway!
Yet another thread derailed and turned into pointless bickering by Ree from California.
Call sign CG, no its not - no you didn't.
CG & Poster #24, with respect - why dont you two guys give it up?Unfortunately, neither of you know what you are talking about?
Poster #24 attacking the man proves it.
The OP started by claiming previous "vents" - now "bricked in."
Low level "vents" i.e. air bricks vent suspended floors.
The correct position of a DPC on the inner leaf of a suspended floor is in the bed under the joist tails.
Having the DPC under the joists sets it well below the FFL.
The FFL does not have to be "the height of the ext DPC"
The correct position of a DPC on the outer leaf is 150mm above GL.
He later stated that the floor was solid - i.e. the suspended floor had been replaced with a solid floor.
Obviously, given the above, I was all along referring to a suspended floor - why? because thats what was on the page.
Unfortunately some of the posters got emotional & began to see what was not there.
There are a number of other factors that have not been discussed but whatever, Que sera, sera.

Thanks for all the replies so far.
Removed the plasterboard & skirting just now.
Am i assuming rightly that the black plastic sheet is the dpc. It goes in to the brickwork(poor picture again) sorry.
Where the cable goes into wall & the small hole to the right of the circle both go as far as the cavity. Both have expanding foam in it as per last two photos.
Anything else i should have mentioned or taking a pic of, let me know. Many thanks.

OP,
As you acknowledge, the pics are pretty poor - maybe you can supply a bit more light?
1.There are a few signs of damp on the blockwork but you report previous penetrating damp. What condition was the back of the plasterboard in?
2. If you knocked out a couple of blocks it would enable you to look into the cavity for any cavity rubble bridging the DPC & DPM or mortar on wall ties?
And see how far the black membrane goes under the blocks?
3. The membrane (the DPM) has been installed incorrectly but maybe it works?
4. As requested earlier, why not measure down from the window board to the floor & then mark that dimension on an outside pic?
