Extension vs conservatory with a guardian roof

This is the guidance i got

As I am having a tiled design roof we can remove the doors and kitchen window under building regulations and no planning permission is needed. If this was a glass roof conservatory then you would need planning permission as the thermal efficiency is not the same.

does anyone have experience of Guardian roofs?

LOL... Whoever gave you this 'guidance' was either an idiot or a liar.

Yes, you don't need a planning permission, but you do have to meet building regulations. 

You can even build an extension under permitted development rules (no permission needed), but this doesn't mean that it can be any structure with a tiled roof ignoring BRs. And there are two different departments in your council -  (1) Planning (permissions) and (2) Building Control

Not wishing to detract from your comment about the need to comply with building regulations (I agree).... but it can't be assumed that planning consent won't be required as well.

Permitted development only applies in certain circumstances, and the OP hasn't given us enough detail to know whether the conservatory/extension would be PD or not.

They checked the permitted development. I am j a detached house and council says I can build 4 metres frrom back of my house.

so my conclusion from above is that I need to check building control. Does this vary by council ?

The way some of the regs are interpreted vary among different councils, but most, like the one about external grade doors and conservatories, are the same in England and Wales.

As I said, THEY are either idiots or liars. Permitted development has NOTHING to do with "thermal efficiency".

I have checked the permitted development. Don’t worry about that. I am asking about Building Control

Who are "they"?

Has the planning authority for your area given you that advice - in writing - specific to your house, or is it 'they' have looked on a council website for generic permitted development advice and seen that information?

The comments you say 'they' are making and you have quoted on this thread are confused and muddled (i.e. their comments not yours).  It is the kind of confusion often heard when salespeople want to convince a customer that everything is Ok and just sign on the dotted line.  Ultimately the legal responsibility to comply with building regulations* and planning law is yours, if you don't know what the requirements are then you need to confirm them with people who you can trust (for example the council).  (*the BR responsibility is shared with the builder, but often they'll be long gone)

You started the thread by saying you can't afford £80k for an extension, but can do the alternative for £45-50k.  Ask yourself what you'd do if, having spent £50k, you find the council taking enforcement action and you need to find another (say) £15k or £20k to rectify the issues.  If you couldn't fund the additional cost then you need to be absolutely certain what you are planning to do is 100% in compliance.

Permitted development has been verified by a few sources. Architect, council website . 3 or 4 contractors. That’s not the issue.

i will call building control on Monday. Appreciate it.

 My question is still has anyone had experience of guardian roof

Why did you need an architect for this? And if you did have one involved, he should have advised you about the BR in the first place, not that it's a permitted develplment (an obvious fact IMO for replacing a conservatory roof). AFAIK, typically it's the architect who does thermal efficiency calculations.
You seem to be dealing with a bunch of incompetent people.

Not an obvious fact - for example on a listed building, in a conservation area, or if the conservatory had full planning consent originally.
