We're working on several large-scale social housing projects. 400 units per project is an example. And are experiencing issues in terms of gaining access to a small percentage of the portfolio around 5%. Namely, due to vulnerability, health, social issues, etc. We're trying to work with the spirit of the past and gain access to every dwelling. But this is a real issue across most of our projects. What opportunities are there still to proceed with external fabric works? For example, EWI, compliantly, under the PAS. Would an archetype appraisal be sufficient short term with a view to carrying out an internal assessment to verify condition and ventilation improvements at a later date? Perhaps during a void relet, kitchen replacement works, etc?
