I think the challenges in maintaining this standard over the next 25 years are going to be numerous. We have an aging population who will require adaptations to their properties, we will have a responsibility to make properties as energy efficient as possible to minimise tenants' fuel bills and we will have a competing agenda with the drive to reduce carbon emissions of exisitng properties, which may take away funds which would otherwise be used to maintain properties.
In Exeter we have a relatively old stock of properties and keeping those properties to a minimum standard is hard enough now, but in 25 years time that cost will be unmanageable unless we can adequately fund our programmed works year on year.
Concerning a minimum standard, I think, sadly, that this will largely be determined by resource. It would be self-defeating to allocate a property where the tenant is then immediately back on the housing register with a priority to move on the grounds of disrepair. However the standards used to prioritise applicants on the register as a result of disrepair are pretty minimal and if funding forces us to just aim for this (no Cat 1 hazards for example) I think we would then struggle to find tenants who are proud of their properties and may even struggle to afford them.
