Last month’s announcement of a fresh inquiry into proposed government reforms to the UK’s National Planning Policy Framework (NPPF) by MPs on the parliamentary levelling up, housing and communities committee is certainly welcome news.

The planning system has been feeling the strain for some time. It has come under a prolonged and intense period of scrutiny for several reasons, the most obvious and frustrating being the sheer amount of time it takes to go through the process.

This has contributed to a growing case backlog that is already damaging the building sector and holding back the UK economy.

The problem is illustrated by a concerning trend around the number of buildings being recorded as disused or derelict. Between 2019 and 2022, the total increased from 600,000 to 650,000, indicating a direction of travel that should be cause for concern for the government and sector stakeholders.

The issue is compounded by a feeling among peers that it is easier to reject planning applications than it is to approve them. Dialogue with officers at local planning authorities (LPAs) is not encouraged, while many working within LPAs appear to be uncontactable when in reality they are often faced with overwhelming workloads.

We have reached a point where acknowledging and highlighting problems is no longer useful. The government needs to be bold and consider a radical shake-up of how planning works

And, when applications are finally considered, although the system handles site-specific environmental considerations effectively – as it should – the same cannot be said in terms of the building’s technical design: the new ºÚ¶´ÉçÇø Safety Act will only trigger technical review at gateway one for high-risk buildings.

Indeed, many professionals in the field feel a sense of frustration when they are assigned planning officers who do not have the required design or planning experience – a gap in technical competence that could result in permission being granted for designs that are flawed.

But we have reached a point where acknowledging and highlighting problems is no longer useful. Whatever the outcome of the committee’s findings, the government needs to be bold and consider a radical shake-up of how planning works.

To address the issues around backlogs and technical competence being spread so thin, there are, unfortunately, not a lot of obvious choices. Put simply, we can either look at dumbing down the planning process, making it shorter or simpler to meet the bar of being in the public’s interest, or add resources to improve the current system. Alternatively we could explore a whole new process.

A centralised pool of talent can build and maintain state-of-the-art, sector-specific expertise for technical consultation on major projects

Although finding extra resources to improve the current system is obviously desirable, it does not look like being achievable in the short term, especially given the well-documented financial and skills shortages. So a new approach is needed.

Instead of having planning experts dispersed geographically among LPAs, I believe the creation of a centralised pool of talent is needed. Over time, it can build and maintain state-of-the-art, sector-specific expertise for technical consultation on major projects.

Why would this work better? There are many LPAs that lack the the technical expertise to determine whether a design is missing an opportunity or has a technical shortcoming. A new, technically-centred body would ensure that all major projects are vetted on a like-for-like basis, regardless of where they are being proposed.

This would remove inconsistencies in the system. Indeed, rather than represent something of a postcode lottery, a national body would be responsible for raising and maintaining long-term, state-of-the-art competency for key sectors such as housing and masterplanning, transport and aviation, healthcare, education and even larger retrofit that can advise on applications all over the country.

A sector-driven approach may help to retain competency in the longer term and save the need for ad-hoc design review boards which are eventually disbanded, losing all built-up knowledge in the process. CABE (now DesignCouncil CABE) is a case in point with HS2, the London Legacy Development Corporation (LLDC) and Old Oak and Park Royal Development Corporation (OPDC) coming down the track.

In practice, a centralised approach to vetting complex, major applications could either be delivered through the extension of arm’s length bodies (ALBs) that already exist or the planning inspectorate. Perhaps Homes England, for example, could have its remit added to for the technical vetting of major residential masterplans outside of London in England?

I would like to see the development of a site classification tool to aid planners and applicants alike from the start with an overview of the level of consultation detail that a site might statistically require

Or, as has been the case with the Health and Safety Executive, whose remit has been expanded under the ºÚ¶´ÉçÇø Safety Act, the planning inspectorate could take centre-stage as the government agency for consulting on all major applications in addition to nationally significant infrastructure projects (NSIPs) which it already operates the planning process for.

To help pave the way for this, in our post-AI world, I would like to see the development of a site classification tool to aid planners and applicants alike from the start with an overview of the level of consultation detail that a site might statistically require. Quite often, an applicant and case officer will only start to understand the complexity of a site after prolonged discussions, and I believe we have the tools and data to ensure that all parties can allocate the right level of resources to improve productivity.

A site classification, akin to listed buildings or structures, would help frame all applications. Think of it as a sort of public transport accessibility level (PTAL) equivalent, one which for any grid location a LPA case officer and applicant can agree from the outset the level of complexity that a site is likely to require their pre-application and final application documentation to cover.

The ideas need to be explored in granular detail to see if they are workable and desirable

This would be linked to commensurate application fees, level of LPA technical competency, LPA design review and, in turn, the likely length of the determination period. Simpler grade threesites might be determined quickly; complex, layered and historic grade one sites might take longer than the current statutory period.

The above does not suggest that a centralised, sectorised planning consultee is necessarily a silver bullet solution to all the problems the system faces – the ideas need to be explored in granular detail to see if they are workable and desirable among the stakeholders involved in planning applications.

But the time has come to put forward and discuss actions that can unlock the potential of the UK’s building sector. This would place the industry on a better footing to meet challenge of responding to the climate emergency.
