Best Mortgage Lenders, UK
Following is a list of the top 20 mortgage lenders in the UK ranked by gross mortgage lending.
In 2014, Lloyds Banking Group, Santander and Nationwide Building Society were the three largest mortgage lenders in the United Kingdom, with combined gross lending of £94.7 billion (US$147 billion), and the top 10 lenders held a market share of more than 85%. Several of the lenders in the table below have since combined, so the rows no longer represent independent lenders. Fixed-rate mortgage pricing in the United Kingdom is competitive between the large banks, the mutual building societies and specialist lenders; current best-buy tables are published by comparison services and are not reproduced here.

The figures above are gross mortgage lending for 2014, and several of the lenders listed have since combined. Following High Court approval on 23 February 2026, Virgin Money’s business, including its mortgages, current accounts, savings, credit cards and business accounts, transferred to Nationwide Building Society on 2 April 2026. The Clydesdale Bank brand and website have been withdrawn; that business had become part of Virgin Money and passed to Nationwide with it. TSB is joining Santander, and its mortgage lending will form part of the Santander UK group. The Co-operative Bank has proposed transferring its business to Coventry Building Society from 1 January 2027. The Royal Bank of Scotland Group now trades as NatWest Group, and Royal Bank of Scotland continues as one of the group’s customer brands alongside NatWest, Ulster Bank, Coutts and Lombard.
