I'm trying to figure out the cheapest lockshields that Screwfix do, however I'm a bit stumped.
Their angled radiator valves (16343-72) have a picture of a 2nd cover next to them, as if you can swap the covers from knob to lockshield. Nice at cheap at £1.29 each.
However, the Pegler valves (75592-72 and 93129-72) have separate items for knob valve and lockshield valve (and both £4.99).
Are the £1.29 ones suitable for use as lockshields? Also, should I find them cheaper at a local plumbing place, or is £1.29 a reasonable price?
Their cheap TRV's (10023-72 - £4.99) are these any good? The Pegler one looks nicer (19052-72) but costs £8.99. What's a reasonable price for a TRV? I'm planning on needing 5 or 6 of them (and also lockshields).
Thanks
