Strangely enuf i'm not
Tho i might have a look on the odd chance i might have overslept the night before & am suffering a rare occurrence of insomnia

I read the regs when I have to, but usually in conjunction with a professional in a given area of expertise, quite a bit of it is open to interpretation.
In addition to the UK Buildings, several Local Authorities and County Councils have gone a step further and added their own requirements.
In summary, every new home already has to meet minimum energy and carbon emission performance requirements, a home has to be super energy efficient. There are high insulation requirements, rules to prevent thermal bridging, low u value requirements on windows, roofs and walls. Combine that with mandatory air pressure testing to measure leakage. The result is that you end up with a highly efficient home, and therefore the energy required to heat it is minimal, often negating the cost of installing solar.
For example if you have a Passiv house or even near Passive, you will use hardly any energy for heating, as it heats itself.
That all said, Solar is coming in as mandatory (for the majority of new builds) in the next update as part of the Governments Future Homes initiative.
@webpunter, essentially, you can put your placard down
