WHY SORT CODE 30 80 88 chiswick W4 branch name but chelmsford address?

The sort code 30-80-88 is associated with a specific bank branch, which in this case is Chiswick, located in the W4 area of London. However, the address may refer to a central processing location or regional office in Chelmsford. This can occur when banks consolidate operations or use a centralized address for administrative purposes while maintaining branch-specific sort codes for transactions. Always check with the bank for the most accurate and updated information regarding branch details.
