Hi there, This is my first post so please forgive me in advance if I've not posted correctly or if I've supplied insufficient info etc.

I have a question on building regs for a conservatory.

Given the building regs have changed on time, if I replace / refurb an old conservatory that complied with old building reg exemptions, do I need to comply with the new exemptions or can I get away with the meeting the old ones?

As background info:

12 months ago we bought a victorian terrace house with a small-ish (2 metres x 3.5 metres) conservatory at the rear of the property.

We believe the original conservatory (uPVC frame & plastic roof) was built in 2000 / 2001.

Subsequent to moving in (and having a rather chilly winter), we put in a new conservatory (aluminium frame, thermally efficient glass etc).

The conservatory is NOT separated from the main house via an external-quality door, meaning it doesn't meet the CURRENT criteria to be building regs exempt.

However it is my understanding that it was compliant when it was originally built (the original 2000 building regs exemptions made no stipulation about conservatories needing to be separated from the main house by a door).

So do I need building regs (or need to fit internal doors) for the new conservatory, or am I OK given my conservatory was technically originally built in 2001?

Just to be clear, I'm not necessarily looking to cut corners or get away with shoddy work. I would just be quite annoyed if I had to fit ugly interior doors to a structure that is infinitely better than what was in place previously (just because the definition of a "conservatory" has changed).

Thanks in advance.

if your built its a new structure that needs to comply with present regs

you can only repair and keep as is
anything that is different in any material way cannot be a repair so a new build
