Help! Which suits to buy in London in the GBP500-700 price range?

[Kakwkei]

Dear friends,

First post in this forum and I would really appreciate your invaluable insight on the following:

Just relocated to London and I will have to build my business wardrobe from scratch. On these grounds, which suit brands would you recommend in town around the GBP500-700 per suit range?

Based on the reading I've done while lurking on this excellent forum, it seems that Boggi (saw a navy blue S. Grisaglia Perennial suit priced at GBP595 in their London store last week), Brooks Brothers (they offer online the Fitzgerald Fit BrooksCool priced at GBP599) and Hackett (they offer online the Mayfair Pick Suit priced at GBP600) are all within my price range and represent good value for the money.

Which of the above would you choose and why? Any other brands that I should also take into consideration at this price levels?

I would greatly appreciate your feedback! My knowledge on suits is unfortunately very limited and hence I can use all the help you can offer!

Many thanks!
