Absolutely, but my question is about the spec of glass, heating and if people have experience of what I want to do and how it has effected their house. Not should I be getting building control involved.

I wanted info from people who have done it rather than a salesman saying it will be ok.

The last thing I want to do is annoy people having just joined up, but if anyone can answer the question that would be great.

People who have done it or done it correctly?

Yup, the price I quoted didn't include that cost but yes, they are dealing with everything.

So they aren't dealing with everything.

Building regs for you extension will be needed. Don't let the salesman call it a conservatory and say it's exempt just to get your money. You will also need heat calcs (saps I think they're called) to get building regs signed off.

Have a look here £149 plus vat for what you need.

Oh and building regs are £534.

Couple of other points, does the other owner know about your plans?

Not heard of electric underfloor heating below the screed, will it work there? It's usually above and it won't work in the way you think.

Are the window company doing the electrics and are they part p?

Thanks for that.

Just to clarify though, I am aware of all the regs I need including SAPs, deeper foundations, double insulated flooring and so on. It's the the temperature thing that is my worry. Will removing the window and door mean the house gets excessively hot or cold given the spec I outlined in the first post?

Thanks, again!

It's a housing association and we have to submit plans to them.

The flooring info looked great, will let you know what system it is when I'm home and have the info to hand.

Yes, all part P.

Also have underfloor electric heating with its own timed thermostat. This is laid beneath a screed that absorbs the heat so acts a bit like a storage heater and stays warm after the heating has switched off.

There should also be a thick layer of insulation below the electric heating. Our floor does stay warm to an extent but it's certainly "a bit like" rather than an actual storage heater!

Don't you mean a thick layer under a hot water system?

Check with them about the heating.

Looks like it can go in the screed.

No, we had our suspended floors changed to solid floors and all the floors had an insulation layer put in, even the areas without underfloor heating. It's made an enormous difference to the comfort levels in the house.
