I have use "pattern" copies of the Drayton, and they have been fine for

Also used those in the past, and they worked fine.

Screwfix is not somewhere I'd go to buy something cheaply. I regard it more as an emergency supplier for once-offs.

BES do them now (they didn't for years), at £18.

Also, try your local plumber's merchant for a box quantity - they might give you a good quote, even more so if part of a bigger order.

Lastly, if you're not in a hurry, keep an eye out for a year or so. I bought 10 or 15 of them at Screwfix trade show (bought directly from Drayton, not from Screwfix) for £12 each including lockshield valves. There was no qty discount in this case, but it was a price for that event only.

I bought TRV4s from here:

around ~£18.00 each inc VAT

Watch out, I ended up with a couple of "pattern" copy Draytons a few years ago after not reading an eBay posting carefully enough. They are complete rubbish.

Yup equally possible. I got mine on the advice of the plumbers merchant that had been doing a particular model for some years and had found it good.

Thanks to all for the suggestions/pointers. The job wont be started until the end of the current heating season so there is no immediate rush. I am just trying to do some homework in advance.
