You dont have to have TRVs if you dont want to. Its just best practice. And no there arent any twin entry TRVs as far as i know.

You do NOT have to fit them on all rads with a boiler change only a new installation.

Good practice is, each bedroom; rooms with over sized rads; rooms with house plants; musical instruments, piano;

Never in bathrooms, landing, kitchens or halls

If your refering to TRVs, i have one in my kitchen and bathroom, should they not be there, for some reason?.

put them where you want long as the room with the stat hasn't got one.

There is a lot of misinformation being given on here!

Its pretty obvious that the best practice is to have TRVs on all rads.

That is also the latest energy efficiency advice as well.

No your room stat is what is used to comply with part L's requirement for a boiler interlock.
The Trv's are for Efficency,comfort and control.

Whats the point in fitting a TRV in a cold damp bathroom, or large hall
waste os £15, sometimes open your eyes and see if it will actually shut down.

Most rooms have undersized rads, go to a new build, microbore tiny rads with TRV, we have to fit then coz regs say so, rubbish realy.

Old Victorian house full of TRVs watse of money, good earner

More rubbish comments.

New builds have smaller rads and pipe because they have to have smaller heatloss,averagely less than 35W/M2.
If you've ever got involved with heating design you'd understand radiators sized correctly may not need massive pipes.major builders get manufacturers in to do their design not Joe bloggs that is some soletrader that decides every room need a 6x12 k2 under the window.

Don't say you know how to use mears calculator as they're not accurate.
