Broadly, yes, but you're sure to encounter exceptions.
This comes from an episode of Map Men on Jay Foreman's YouTube channel.
It's about how to pronounce British place names, and why to pronounce them that way.
"(...)No letter of the English alphabet is safe from being pronounced any of dozens of different ways—including not at all. Thankfully, there are some general rules you can stick to, and because we are nice, we'll help the un-British [?] amongst you through a couple of basics.
- Cester is pronounced /stə/ - Leicester, Worcester, Gloucester.
- W at the start of the final syllable is silent - Norwich, Berwick, Southwark.
- Er is pronounced /ɑ:/ - Berkshire, Clerkenwell, Hertfordshire."
Do you approve of this?
Broadly, yes, but you're sure to encounter exceptions.
This is where GB Shaw's ghoti (= fish, from enough, women and station) kicks in.
I am not sure what you mean by that.
If you are asking whether I approve of Jay Foreman's summary of the pronunciation (in British English) of some English place names, then I think it's OK. I don't think 'approve of' is the right expression there.
If you are asking whether I approve of the weird British pronunciation of some place names, then I thoroughly approve of it. It's a cunning device to enable residents to spot outsiders.

My friend grew up in a town called Towcester.
(Yes, like the kitchen appliance.)
Towing cesters around gets tiresome.
I am not a teacher.
I once heard a joke about -ssexes.
We have Sussex in the south, Wessex in the west, Essex in the east, but people in the north don't get Nossex.
... and don't get the wrong idea about Middlesex.
