Q: what is average rent per sq ft in east london around bethnal green tube station?
The Tea building at the junction of Shoreditch High St and Bethnal Green Road would be approximately £22 per sq ft - possibly a little more. Down the little side streets - which are very popular - you are looking around £20 per sq ft.
Rates payable would be less than £10 per sq ft.
This area is becoming very popular - particularly with startup tech companies - so rents will probably rise. And there is not enough good space available at present in this area.
