Installing TRVs

phoenix__

Hi all,

All our radiators have screw valves and I want them replaced with TRVs. There are 11 radiators to do and I've been quoted around £550 (inc VAT) to supply, fit and ballance. Does this sound reasonable, and if not what would be a reasonable amount?

Also, how much would people expect to pay for a service of a conventional boiler?

Cheers,

Good afternoon: depends on the TRVs, whether the system is drained downed,chemically flushed/topped up with inhibitor and where you are in the UK. I see from your other thread that you recently moved into a Victorian property...have whoever fits the TRVs and services the boiler to check the system water quality as well as the other components of the CH systems. Service cost will depends on the condition of boiler i.e. has it been well maintained, will it require any parts as indicated in the manufacturer's service routine.

Someone will be around shortly to advise a DIY...google is wonderful resource;)

trvs cost from 7 quid each. ie from screwfix.
a handyman should only charge 200 quid max to fit em.
you dont need a plumber for this simple job.



a boiler service is approx 100/200 quid.

Thanks for the advice Canucklehead, we live in London, so I expect will always be on the higher side for anything we get done.

The central heating system was installed 5-6 years ago by the previous owner, they said it had been regularly serviced but I can't see any evidence either way. That quote did include draining but I don't know about the inhibitor (I'll check back with him, along with which TRVs he usually uses).

The system itself is a mains pressued hot water system, and doesn't have the usual storage tanks in the loft that I had in the old house (I don't know how much difference that has on anything related to this).

ormus - I was quoted £75 for a boiler service, so that sounds (too?) cheap if it's normally £100-£200.

Hi...are you saying you have an unvented hot water cylinder with a system boiler? If this is the case the UVC should also be checked out at the same time as the boiler service...make sure your RGI has certification i.e. G3 for unvented.

Btw...£75 is not too cheap for a boiler service in London (speaking as someone who types up quotes/invoices for a plumber/RGI ...my OH, who has worked in London for 30+ years.;)

If unvented is the same as mains pressure (the wording used in the survey) - then yes. I didn't realise there was a special certification for that - the guy who quoted me for the service / TRV installation did say he wouldn't be able to do anything with the hot water cylinder (if it needed anything) but not a problem to do the boiler / TRVs.

Price seems about right to me and at least the guy was honest in that he doesn't have a G3 ticket for the unvented.

Cheers.
