Inspectors have given Kingston Primary Care Trust the NHS organisation which runs non-hospital health services the same two-star rating as Kingston Hospital.
The announcement has been welcomed by the trust, which had feared it could lose one star over an administrative blunder which saw incorrect information supplied to assessment body the Healthcare Commission earlier this year.
It was the second time the PCT's performance has been assessed. Last year it also received two-stars out of a maximum three.
PCT chief executive Chris Butler said he was delighted with the news.
He said: "I am very grateful for the hard work and determination that staff in the Kingston health community have shown over the last year.
"Clearly we have made some good progress and we will continue to work hard in areas that need further improvement.
"In the coming year we will focus extra attention around mental health support for our patients and further enhance our GP and community services."
The organisation was judged on nine criteria, including access to GPs, community nurses and other health workers and A&E waiting times, though these are primarily the responsibility of the hospital. Among the trust's achievements were: q Nearly 100 per cent of patients see a GP or practice nurse in 24 hours, an improvement on last year.
q Improvements in the number of patients receiving flu vaccinations and cervical smear tests q Waiting times for outpatients to see a hospital consultant have dropped from a maximum of 21 weeks to 17.
Meanwhile, last week it was reported that Kingston Hospital had also maintained its two-star rating for the fourth year running.
The news was been welcomed by hospital chiefs.
Chief executive of the hospital trust Carole Heatly said: "Staff here work hard to continuously improve the service. We will continue with our efforts and focus will now shift towards improving those areas that have been identified as needing further improvement."
Among areas rated "poor" in the Healthcare Commission's report were junior doctors' working hours and the hospital's collection and use of data about the trust.
The maximum three-star rating allows hospitals to apply for foundation status.
Those that become foundation trusts have greater control of their finances and assets.
