Do you need thermostatically controlled valves for hot water and heating?

I got a survey done on a property and it says that the hot water and radiator system should be overhauled to provide thermostatically controlled valves, is this essential?

Thanks

Building regulations 2006 part L1B conservation of fuel and power in existing homes, soon to be replaced with 2010 B Regs in Oct, yes any heating system should be upgraded for optimum energy efficiency......using 24 hour 7 day programmers, thermostats on hot water cylinder, foam insulated cylinder, programmable room thermostats, thermostatic radiator valves etc.....all of this should, if carried out correctly, reduce your future fuel bills.

It's not essential - the house won't fall down and you won't be sent to prison and your children sold into slavery if you don't.

But any heating system that doesn't have TRVs on the rads might be pretty old by now, they've been commonplace for decades.

On an existing CH system it is not essential - but desirable.

TRVs are cheap to buy and simple for a plumber to fit(or even a competent DIYer)

So certainly not a 'show stopper' for house purchase. However as indicated above, you probably have a very old CH system - so make allowances for that in your purchase.

On a new CH system, again as stated above, they are mandatory.

Many thanks all, how much roughly will it cost to get this installed and are there certain models that are better?

Although not completely essential, is it cheeky to try and ask for a reduction in the offer I put in originally for the property?

No, it's pretty much standard practice to at least try to get back the cost of the survey-depends what else it throws up and how much you want the property.

Drayton TRV4 are about £20 each. Danfoss about £12 each. + fitting.

Of more concern is what make & model is the boiler. How is the hot water cylinder insulated. Is it possible to have heating and hot water on separately (a lot of older systems you have to have hot water on if you want any heating).
