I've had my babies at home (and I'm in the US, so don't take my advice as the voice of experience) but a DF is a labor and delivery nurse and she's told me that many nurses can be pretty cynical when a mom has a really specific birth plan and feel like they are being micromanaged. How you word things can make a big difference in how cooperative the nurses will be.
I would consider writing in the plan that you want skin to skin and that you want your Oh to dress the baby. I think that puts you in control of what goes on the baby without the risk of your birth plan coming off as too prescriptive.
FWIW I think it is a shame that the "tone" of the birth plan can affect how inclined the nurse is to comply with it, but that would be in the back of my mind. Maybe there is a different attitude about birth plans in the UK.
