Short story;

I'm reliably informed that I need to change the pressure regulating
valve in my flat, and I've been told to expect a price of
=A3120-=A3180
for the valve, and =A3120 upward for labour.

Does this sound fair?

Not sure what you mean, from your post, but if it's one that on
the mains cold water supply, not part of the boiler, is it one
of the type on this page?:
http://www.plumbworld.co.uk/343-0000 if it is, then it sounds
a little expensive for the part at least.


The valve is on the mains cold water supply, not on the boiler

It is the third unit sitting on the pipe. Firstly there is the stop
cock URL: http://www.plumbworld.co.uk/329-0000, then there is a
'double check valve' (very similar if not identical to URL:
http://www.plumbworld.co.uk/339-0000) that I was told prevents dirt
(!) coming through and contamination of mains supply, then there is
what I am told is the 'pressure regulating valve'.

Here's my attempt of a schematic diagram:


-- mains cold water coming into the room

-- stop cock

-- double check valve

-- pressure regulating valve


It does look very similar to many of the ones in your link, in
particular this one here; URL: http://www.plumbworld.co.uk/343-1890.

However it says 3,5 bar on the black nob and you cannot adjust the
pressure.

Looking at my quote;

parts =A3120-=A3180
labour =A3120+

=3D =A3240 - =A3300


Should I try and fit this pressure regulating valve myself?

The last time I had the plumbers in they simply checked every other
element of the pipes etc, so I am sure this is actually my problem.

Would I be stupid to do this myself? I guess I need a couple of
spanners but that's it, right? [a]

[a] procedure; (1) stop the water at the mains; (2) drain water from
the pipes; (3) close the stop cock; (4) fit the new item; (5) bring the
mains pressure back on; (6) slowly open the stop cock to ensure no leaks
