599 GP practices closed between 2010–11 and 2014–15, while 91 opened and average practice list size increased from 6,610 to 7,171. In 2016 there were 7,613 practices in England, 958 in Scotland, 454 in Wales and 349 in Northern Ireland. There were 7435 practices in England and the average practice list size in June 2017 was 7,860. There were 1.35 million patients over 85. There has been a great deal of consolidation into larger practices, especially in England. Lakeside Healthcare was the largest practice in England in 2014, with 62 partners and more than 100,000 patients. Maintaining general practices in isolated communities has become very challenging, and calls on very different skills and behaviour from that required in large practices where there is increasing specialisation. By 1 October 2018, 47 GP practices in England had a list size of 30,000 or more and the average list size had reached 8,420. In 2019 the average number of registered patients per GP in England has risen since 2018 by 56 to 2,087.
