Ms ?ine Stapleton:

On the issue of cost inflation, the average amount we have been devoting to the retrofit programme has broadly increased in line with inflation, which has been approximately 20% over the past few years. We are aware that sometimes there are other enhancements local authorities wish to make. We are trying to balance getting the maximum effectiveness from the envelope of money we have with perhaps a desire sometimes to do a little bit more. The local authorities can if they wish contribute some of their own resources if there is a particular issue they feel would be useful to take the opportunity to do as part of a retrofit programme. They engage with us around these issues, so we will continue to engage with them around some of the challenges they feel are there on the cost, but we have overall been increasing the average costs.
