WREXHAM Against Stock Transfer (WASTe) has been challenging Wrexham Council on its sums.
At a meeting held last week, WASTe called into question why the council needs £21,000 per council house to meet the Welsh Quality Housing Standard by 2012.
Wrexham County Borough Council has said that it will need to find a total of £250m for its 12,000 council homes, and WASTe wants to know how the council has arrived at this figure.
WASTe spokesman Maurice Jones asked: 'Why aren't Wrexham's housing bosses able to cope when other councils seem to be able to? We believe the council is bumping up the figures as much as possible to make it appear impossible to meet the housing standards set by the Assembly by 2012.
'The hidden agenda is to present stock transfer as the only possible alternative,' he added.
WASTe campaigners say the council has vastly overestimated the cost of new kitchens and bathrooms, and argue that many of the council houses already have kitchens and bathrooms that meet the WQHS.
The council has hit back, saying there is more to the Welsh Housing Quality Standard than just kitchens and bathrooms, which only form a small part of the money needed.
Paul Spruce, accountant for the Housing Department, explained that costs such as plumbing and wiring are covered in the budget and that building costs are high at present.
Mr Spruce pointed out that Wrexham's figures per house were lower than Newport and Swansea.
'Money is also needed to carry out work on the whole house and environmental works, including roofing, exterior painting, rewiring, parking provision and landscaping,' he said.
The council says the figures were arrived at when their housing stock was surveyed and audited. The survey was carried out by an external company and then went through three separate audits.
Mr Spruce added that the council does not receive any Council Tax funds for environmental improvements or regeneration of the area council houses are built in. All the funding for council housing comes from rent and not Council Tax.
'We would like to keep rents low,' he said. 'We have not built a new council house since the mid-70's, some of the existing houses have massive structural problems. The issue is where are we going to be in 20 years time? We already have a lot of people on the waiting list for Council properties.'
Council Leader Aled Roberts said: 'Following the 'no' to transfer Wrexham Council's housing stock to a not-for-profit organisation last year, the council has had to take some tough decisions to balance its books.
'After the vote certain people said they could find the money from elsewhere, others thought the Welsh Assembly would stump up the cash to bail Wrexham out. But Wrexham faces the same problems as many other councils, and it quickly became evident that the Welsh Assembly would not come to Wrexham County Borough Council's rescue on this issue.
'This in-depth survey will give us a clear steer on how our tenants want us to move forward and should give them the opportunity to make their own choices without faint promises from certain quarters that unfortunately cannot be delivered upon.
'We are not rushing into anything and will analyse the survey results carefully before moving onto the next stage. We are convinced that our financial calculations were correct last time, but as part of the process we will revisit the figures.
'Our tenants can help us achieve an acceptable way forward based on the robust figures available to us and the desire to have first class council housing areas in Wrexham County Borough.'
