Who can prepare a pre-redevelopment audit

No single qualification exists for a Pre-redevelopment Audit, which is why the question of who can prepare one comes up so often. There is no licence, no statutory competent person and no protected title. What there is instead is a set of skills the audit needs and a separate legal duty, sitting right next to it, that does require a competent surveyor.

Getting those two apart is the whole of the problem. An architect who commissions a sustainability consultant to produce a pre-redevelopment audit, and assumes the asbestos position is covered, has bought one document and needed two.

What the audit is for

A pre-redevelopment audit records what is in an existing building before it is demolished or stripped out, so that materials can be reused, recycled or recovered rather than sent for disposal. It quantifies the structure, the envelope, the fixtures and the fittings, assesses the condition and reuse potential of each, and sets targets for diversion from landfill.

In planning terms its main home is the circular economy. The Circular Economy Statement required for referable development in London draws directly on the audit, and the audit supplies the baseline against which reuse and recycling commitments are measured. Outside London, authorities with circular economy or waste policies in an adopted plan ask for the same evidence under different names.

The audit also feeds the demolition method, the waste management arrangements on site and, where a BREEAM assessment is being run, the credits that reward pre-demolition auditing and material reuse.

Why no single profession owns it

The work spans four disciplines and no institute claims the whole of it.

Material quantification is a quantity surveyor's skill. Assessing whether a frame, slab or facade can be retained or reused is structural engineering. Setting diversion targets and writing the circular economy narrative is the territory of a sustainability or circular economy consultant. Identifying hazardous materials is occupational hygiene and asbestos surveying.

In practice the audit is usually led by a sustainability consultant or a demolition contractor's technical team, with a structural engineer input on retention and a quantity surveyor input on quantities. That arrangement works. What does not work is one discipline writing confidently outside its range, which is the pattern behind most of the audits that get sent back.

The asbestos survey is a separate legal duty

The Control of Asbestos Regulations 2012 require a refurbishment and demolition asbestos survey before refurbishment or demolition work starts, where asbestos-containing materials may be present. That duty sits with the duty holder, it is enforced by the Health and Safety Executive, and it is not satisfied by a planning document.

The survey has to be carried out by someone competent, working to the methodology in the HSE guidance on asbestos surveys, and it is intrusive by nature. Surveyors working to an accredited inspection scheme give you a stronger position on competence than those who are not.

Three points follow for anyone programming this work. The refurbishment and demolition survey is destructive, so it needs vacant possession or at least controlled access, which rarely aligns with the planning programme. Its findings change the demolition method and the cost. And a management survey, which is what many landlords already hold, is not the same document and does not discharge the duty.

Other hazardous materials sit outside asbestos and still need identifying: lead paint, refrigerants covered by the fluorinated gas regime, polychlorinated biphenyls in older sealants and light fittings, and waste electrical equipment. Say in the audit who assessed each, and on what basis.

The skills the audit actually needs

Read that table as a list of sign-offs rather than a list of people. A two-page audit with one author covering all five columns is usually a desk exercise, and officers who deal with circular economy statements regularly have learned to look for the structural input first.

What to ask a prospective author

1. Which schemes of this building type have you audited, and can you show a redacted example that reached a planning decision.
2. Who will do the structural retention assessment, and are they chartered.
3. Is a site survey included, and does it involve opening up, or is the audit desk-based from drawings.
4. How are quantities derived: measured from drawings, from a point cloud, or estimated by floor area.
5. What is excluded. Asbestos, other hazardous materials, services and below-ground structures are the usual gaps.
6. What professional indemnity cover is in place, and does it extend to the reuse recommendations.

Question three separates the serious proposals from the rest. An audit written from drawings alone can quantify a building and cannot tell you the condition of anything, which matters because reuse potential is a condition judgement before it is a quantity.

The commercial point about exclusions is worth pressing. A fee that looks low because the asbestos work, the structural assessment and the site survey all sit outside it is not a low fee, and comparing two proposals with different exclusions is the most common procurement error on this document.

Where London's requirements bite

Referable schemes in London involving demolition are expected to submit a pre-redevelopment audit alongside the circular economy statement, in the format set out in Greater London Authority guidance. That guidance prescribes the reporting template, the material categories and the reporting stages, including post-construction reporting against what was promised.

Read the live guidance rather than a summary. It has been updated since the London Plan was adopted, and the reporting template is the part most likely to have changed. Boroughs also apply their own thresholds below the referable level, so a scheme that is not referable may still need the audit.

The post-construction reporting stage is the one that catches developers. A commitment made in an audit at application stage has to be evidenced later with waste transfer data, which means the demolition contract has to require that data from the outset.

Naming, dating and defending it

Put the author's name, qualifications and the date on the audit, along with the version. This sounds administrative until the scheme reaches appeal or the condition reaches discharge, and the reasons it matters apply to every planning document: a named author and date is what allows anyone to tell which version of the guidance the work was done against.

Where junior staff do the measurement and a senior author signs, say so and describe the review. That arrangement is normal and defensible when it is disclosed, and the conventions around graduate work signed by a chartered author apply here as much as anywhere. What undermines an audit is an unexplained gap between the apparent authorship and the evident depth of the work.

The honest uncertainty in this field is how much weight an officer will give an audit that recommends demolition. Retention arguments are being tested harder than they were, and an audit that reaches a demolition conclusion without a serious retention option assessed is now more likely to attract a question than it was three years ago. Build the retention appraisal in, even where you expect to argue against it.

Councils usually expect this document from a suitably qualified author, and professional review before submission is strongly advised. The same competence logic applies across the specialist reports, including the question of who can prepare a health impact assessment. This is general guidance, not legal advice, so check the position with your local planning authority or a qualified professional before relying on it.
