Building regs standard for renovated floors in 2007?

This is from the approved plans for the floor section in my house, passed in 2007.

 

85mm polyurethane insulation in the floor is a slight puzzle - it was technically a renovate not a rebuild. From 2007 Building Regs what would the minimum be for that situation? The u-value seems to be about 0.26.

 

I decided to have a little look to respond to a debate on the other thread about how much floor insulation is necessary for ufh to be a practical proposition.

I can see from the 75mm screed why my ufh response has a delay in it, but even with that spec I like it.

Requirement was U=0.22 from memory. I'm sure older versions of Regs are archived on DCLG website.
