The aggregate mortgage data which includes residential mortgage lending, compiled by the Council of Mortgage Lenders, covers Barclays, HSBC, Lloyds Banking Group, Nationwide, Santander, RBS, Clydesdale and Yorkshire Bank.
Out of the 10,834 sector postcodes in Great Britain data is being published on 9,030 sector postcodes covering mortgage lending worth around £885bn.
As expected London postcodes topped the table with £227bn, the South East followed with £161bn while North West postcodes had £81bn of outstanding lending.
Meanwhile at the bottom end of the table, East Midlands postcodes owed £44.5bn, Wales owed £28.5bn and North East postcodes held £26bn of outstanding lending.
CML director general Paul Smee said: "As you would expect strong levels of mortgage lending are broadly correlated with those areas where there is a strong resident population.
“While the dataset covers only three quarters of the mortgage lending market it certainly shows that there are reassuringly few surprises in the postcode distribution of mortgage lending."
The British Bankers' Association is simultaneously publishing a similar breakdown of SME lending and personal loans.
