As the dust settles on one of the hottest political potatoes of the last five years - responsibility for building remediation costs to meet the latest safety standards - it is not inconceivable that those left holding the baby might now explore potential recovery opportunities against any professionals who may have advised on the acquisition of buildings, sometimes whole portfolios, for investment purposes.  If claims against the original contractor and/or design team are time-barred, despite the Building Safety Act limitation period extensions, there is a risk that this may provoke imaginative and arguably speculative claims against building surveyors, property managers or even valuers who advised pre-purchase. Clairvoyance does not fall within the scope of the duty owed, but scrutiny of who knew (or should have known) what and when may well provoke accusations of failures to warn and flag valuation uncertainty.
