London is a major city of around 8,982,000 in Greater London. The housing is mostly The EC area is dominated by converted warehouses, Georgian townhouses and new-build City fringe apartments.

Plumbing pricing comes down to parts and access. CIPHE and WaterSafe are the marks of a properly trained plumber; Gas Safe if they're touching a boiler.
