Local authorities this week hit back at attacks on their Year 2000 readiness, accusing critics of focusing on methodology, not results.
Ten councils and eight unnamed financial institutions this week earned a red rating from the government watchdog Action 2000 - implying they are at "severe risk" from the date bug.
The watchdog called on a range of regulatory bodies to assess the readiness of organisations in what it describes as the UK infrastructure.
Don Cruickshank, the body's chairman, said: "The local authorities that have been designated red are being assisted in leaving that category."
"All will aim to be amber by October," he added.
Local councils in England and Wales were assessed by the Audit Commission, and in Scotland by the Accounts Commission. Rugby Borough Council is to make an official complaint to the Audit Commission about the "tick box approach" that led to its red rating.
And Stuart Powell, the commissioning director of Warwick District Council, said: "They are more concerned with the way we tackled the problem than with what we have achieved."
Bryn Morris, the Audit Commission's associate director, said it sent councils a 27 page multiple choice questionnaire. The questionnaires were completed with auditors' help and submitted with supporting documents. He said the questionnaire had covered planning and methodology, as well as practical achievements.
"For over a year, we've been saying this needs a systematic approach," he added.
Some councils argued that they were fully compliant, but had been rated red only because they had no formal planning documents or contingency plans.
But one Year 2000 project manager at a large UK organisation insisted contingency planning is vital.
"You can be as confident as you like, but it's important to make sure your suppliers or customers can work with your contingency plans," he warned.
