      Got these, nice and stylish
      Ordered, my radiators don't have any adjustable valves, heating is on or off ATM.

      Ordered a load, hope they're what I need.

      How much do u think a heating engineer would charge to fit these?

      Is it actually though? I'm more than happy doing basic plumbing (fitting toilets/sinks/etc..) but I'm worried I'll drain the system and crack on... Then 4 hrs later I'll still be swearing at the first radiator since after 30 years of hot and cold cycles it's all glued together and won't go back together right and however much ptfe tape I use it won't stop leaking. That said I'm keen to add trvs and my plumber will probably charge an absolute fortune to do the job. (he's a great heating engineer but pricey). So honest advice would be grand.
      A decent pair of gland pliers and some adjustables and you're off. Worst problem you might have is air locks re filling the system 😃
      Thank you for posting, that has saved me lot of money. 🔥

      Should be straightforward yes, but I'd think twice about doing a lot of rads before winter!
      You can have many issues, it's quite easy to damage existing pipes whilst getting the old valves and olives off.
      It isn't something I'd advise a complete beginner to attempt

      Ouch
      Bought, thanks.
      Seems to me they are always this price... Just a very cheap Drayton probably lent their name to some pound shop trv to con everyone.
      I think the trv4's are the Drayton's to get. I did a bit of research and went for a 1 x Danfoss RAS-C² White / Chrome Angled TRV 15mm x ½" (70871). Worth looking at these for a few quid more.
      The price to fit the valves will vary a fair bit depending on quantity fitted and your location. If you have 10 radiators you could expect to pay around 40-50 per rad parts included. If you want one or two fitted you’ll likely pay double that per radiator, to compensate for time spent
      draining down and re filling/venting your system afterwards, especially if your system is open vented. As open vented systems can be prone to air locks/ blocked cold feeds which can be a nightmare to deal with. Hope that helps

      Yes agree - TRV4 are their best ones. And if you head over to toolstation right now, they are selling the TRV4 plus Lockshield at 35% off - £19.99 each. Product code 61277. I could/should maybe add it as a separate deal, but (a) I bet someone else already has, or is in the process of, adding it?! and (b) if so, I'll get flamed for repeating an existing deal and the hassle just ain't worth it !

      Wow that’s an amazing deal

      +1 for the TRV4’s. This seems a decent price for this one though

      Extremely easy, I wouldn't even think of hiring a plumber just to change these.

      And if you do decide you'd rather hire a plumber, make sure you drain your system and then fill it back up, no point in paying for him to stand around.
      Well worth fitting if you have no trvs, having an olive puller is highly recommended
      If you have speedfit 10mm pipe like me bung one of these in the bottom of the valve to make these trvs fit

      bung in header tank - cross your finger and toes and off you go!
      Not really that expensive if u actually work out what we have to pay out for ie, insurances, vehicle, tools, gas safe registered it soon mounts up, we also have the same out goings as everyone else. Plus we guarantee our work. Leave job clean and deal with any other issues and out knowledge is priceless.
      Make sure you diy’ers leave one rad without a TRV otherwise you will dead end your system.

      I got one of these trv4's that you mentioned free with my radiator. My builder is fitting my radiator next week, should I get him to put it on too, what exactly is it? Basically a knob to turn heating up or down?

      How? I thought each rad joins a bigger run of pipe so even if you turned all the rads off the boiler would still push hot water round the ring of pipe?

      Who are you trying to convince? Sounds like £40 per hour from posts above. For comparison, a self employed pharmacist is paid about £20 per hour, has to pay for insurance, vehicle, professional registration, and has the responsibility that an error could have fatal consequences; not to mention financial debt from 5 years training. IMHO, many plumbers' rates are excessive.
      Edited by: "Stu.C" 23rd Sep
      You fancy actually reading that persons 1st post it was £40 a rad and the plumber supplied the parts, so these here rad valves vary from £15-£20 at the time they are only on offer at the moment so technically the bloke would have been earning £20-£25 per rad. 5-6 rads in a typical house £150 a day. Take his £20 a day off running his business. From insurance, fuel, van maintenance, we dont get paid holidays or paid sick days, not to mention the tools we have to purchase and weeks we have to take off unpaid for recapping on training as well as paying for the course too.

      I had the same issue with an old system of radiators which I had a plumber renew the TRVs this summer. Watching him do it, yes it looked like a DIYer could do, although he struggled with a few stiff nuts. Overall though, if your radiators then are left cold at the end of it all, especially with an old system or radiators, do you want to risk a freezing house come winter?

      He charged 330 for labour/parts for doing 6 rads. If they charge by the hour the draining/refilling takes the most time so you could drain it yourself before they arrive. He then left me with a few rads that wouldn’t warm up and initially tried to say that was a central heating/boiler issue and not what he came to fix! Got em working in the end before he fled - it maybe worth doing a system flush at the same time as I presume an old system will have a lot of gung that was clogging parts up.

      These are always a 10er. (cheaper in bulk too)

      Im not one to price bash, I'm happy to price up jobs and say no if I feel its too much, but say 30 a rad (what's it take after draining? Not 20 mins to fit these?)

      Its not 150 a day, it's 150 for about 3 hours work. Extra half hour for draining and refilling, call it an hour.

      I think the price should reflect the job, and for a job that only requires an adjustable, I don't think you can justify such a high cost because your other tools and resources cost so much.

      If the price was averaged out, I'd get it, but I guarentee it'd be rare to find a plumber who will only charge 20 an hour (160 a day) to fit a full bathroom. I know plenty of people had one fit in two days, and none of them were only charged 320, more like 1K. This I put down to the tools, skill required, and resources, but it can't be both ways

      As for holidays and courses, that's pretty much any skilled self employed worker ever. We all have to take that into consideration, I just don't think such a menial task as changing TRV's should be charged at full price.

      Your points do not justify double the hourly rate versus a pharmacist; and I doubt that changing TRVs on a radiator could result in fatal consequences. (Also, pharmacists undergo re-validation every year, not every five years.)

      Nothing too difficult about fitting radiators or valves, it is really common sense. Drain the system, replace the valve and top system back up. The worst scenario is you have t o modify a bit of pipework. As far as I know you do not have to be gas safe registered to change valves as you are not messing with gas and there should not be fatal consequences unless you class a water leak fatal

      Leave well alone if you cant figure that out, 15mm pipe attaches to valve that screws in to radiator. It should be a straight forward swap.You disconnect pipe, unscrew valve and screw new one in, worst scenario is pipe may want modifying or a reducer is required.

      Some boilers require the cover taking off to vent the boiler when filling.Once you take the cover off it is classed as working on that appliance and certain checks are required to carried out. Ring Gas Safe and ask if non gas registered people can do that. They will tell you any person can do wet work but inside the boiler is a no no.
