Another question! Window ironmongery

[JugglingChaotically]

Can anyone recommend somewhere for ironmongery for windows?
On line or west ish london or close too?
Trad wooden sashes plus some casement.
Not sure stainless steel brushed chrome works in Victorian house but doing lots at the moment and can't see brass in some rooms either now.
Also need key operated locks for insurance??
And would like to be able to look a little open for air in summer when out.
Any ideas appreciated.
Thanks

Thanks Piglet john. Just what I needed.
Have spotted all I need on there.

Insurance requires key locks on all windows. For the sash ones do you think the Rola wooden sash window stops are good security?

the
Rola Wooden Sash Window Stop - 19mm - Pack of 2 - Brass
is very neat.

Also look at the
ERA Vertical Sliding Sash Screw - Brass - Pack of 6
and similar in other brands

A Screw (what I call a dual screw.) is neater than a Stop, and also stops the sashes rattling.

You need one each side.

may be cheaper

Thanks for that - much clearer now!
