I think this summary from the BBC, which I have posted elsewhere, is fair:
Keir Starmer's record as prime minister
Ben Chu BBC Verify policy and analysis correspondent
Keir Starmer has overseen a number of changes since he took office in July 2024 - here's a closer a look at his record as he prepares to depart office:
Economic growth picked up - The UK economy registered the fastest growth among the G7 nations in the first quarter of 2026, expanding by 0.6%. However, many analysts do not expect this to last due to the war in Iran.
Immigration fell - The total number of Channel crossings last year was the second highest on record after 2022's peak under the previous Conservative government, though overall immigration to the UK and net migration have both fallen significantly.
NHS waiting lists down - The overall number of waits for treatment in England in April was 7.22 million, down from 7.62 million in June 2024, a decrease of 400,000.
Energy bills up - The latest domestic energy price cap set by Ofgem, the energy regulator, for the summer of 2026 is an annual rate of £1,862 for a typical household - in part reflecting the impact of global events like the Iran war.
Benefit spending increased - The latest forecasts from the Office for Budget Responsibility show the total UK welfare bill - including the state pension - rising from 10.7% of UK GDP in 2024-25 to 11.1% by 2029-30. Starmer attempted to curb the rising welfare bill, but was forced by his own backbenchers to retreat.
It will be interesting to see how the above backbenchers, and those who have particularly not liked this PM, get on with the PM-in-waiting instead.
