Right. Thank you, Chairman. Well, I can assure you this is my last appearance as Public Services Ombudsman for Wales; I think I said something similar last year when we met virtually, but—. So, thank you very much for voting to extend my term until next March; that's greatly appreciated. I want to thank the committee as well for the ongoing support that we have received from this committee, and also, of course, the great work that was done in terms of extending our powers, which came into effect just before the pandemic, though I'm very pleased to say we have been able to use those powers successfully despite that. Clearly, the year in question for this annual report was a challenging one for us, but it was far more challenging, if we're honest, for those people at the front line, particularly in terms of social care, health services and so forth. So, I think it should be appropriate that we note our respect for the great amount of work that has been done by bodies in our jurisdiction during that year in question.
But I want to thank the staff of the office as well for the fantastic way that they came together and made sure that we were able to respond and were able to sustain services throughout the pandemic. We did see a reduction, the first reduction, in the number of complaints coming to us about public services—I think the first reduction in about 10 years—though it was interesting to note that code of conduct complaints went up 47 per cent. So, for those of you with an interest in local government, and I think for all of us who have seen the new celebrity status for Jackie Weaver because of one incident in eastern Cheshire, well, there have been many, many more incidents in town, community and local authorities across Wales during this period. But we were able to respond; we were agile. I'm very, very grateful for the work of the management team, and certainly my two colleagues here, Chris and Katrin, in being able to make sure that we were working virtually almost immediately, and that, having had this lag, this slight lag, in terms of the number of public service complaints coming into the office, we used that time, as a team, to get rid of the backlog.
So, at the end of March, for this year in question, we only had 11 cases that were over 12 months old. That does, of course, mean that one of our key performance indicators does not look very good—it's only 50 per cent, in terms of the rate of closures that were done within 12 months. But, of course, that's a perverse incentive. If we hadn't closed the backlog, then that figure would have been much, much higher. So, we preferred to actually clear the backlog, get as much justice done as possible, so that we could clear the decks for this new year. And I'm very, very glad that we did, because I think we are now in a position where, thanks to this committee, we've never had as many powers as we've had in the past, but also I think we are now feeling the reverberations from the pandemic.
Since the end of the last financial year, we are experiencing increases in volumes of 70 per cent, week on week, month on month, so far, and we're now half way through the financial year. So, that's the basis on which we've pitched the estimate, and also it's one of the reasons for the supplementary. But I want to put it on the record how grateful I am to the staff—they've responded fantastically, they are working hard. Clearly, I have an accountability as accounting officer to you and the rest of the committee for the public resource that we receive, but I'm sure you would understand that I also have a responsibility, as corporation sole and employer, to the well-being of our staff, particularly front-line staff, who are dealing with these aftershocks. So, that's very much the spirit in which we've submitted both documents.
