Heritage policy doesn’t block development – weak professional judgement does
Dr James Weir argues that more planning officers with the ‘confidence to apply the planning balance pragmatically’ are necessary if hold-ups related to heritage concerns are to be avoided.
When the government talks about ‘heritage blockers’ holding “back build, baby, build”, it gives voice to a frustration many developers and their consultants recognise all too well. Pre-app advice is delayed and vague. Officers and committees beat around the heritage bush. Applications wade through treacle or grind to a halt.
But can this really be fixed by policy tweaks alone? A common alarm is to bemoan the erosion of specialist historic environment expertise inside local planning authorities. Indeed, recent Historic England data shows there are now fewer than 800 full-time equivalent heritage specialists across English councils, with just over 500 focused on conservation roles.
This continues a long-term decline which has seen conservation and archaeology staff drop by around a third since the mid-2000s. Historic England itself reports rising caseloads per officer, even as the government seeks to reduce consultation thresholds. This capacity failure is real – but it does not explain why decision-making is so often defensive even where expertise exists.

I would suggest it is not. The issue arises from two sides of the same coin.
In my experience, including within a local authority, planning officers too often lack the confidence to apply the planning balance pragmatically. Objections from heritage consultees are treated as something to be overcome, even when they are weakly grounded in policy or can be outweighed by other material considerations, which is how planning is meant to work.
The other side of the coin is the calibre of heritage consultee input. Where consultee input is driven by protectionist instinct rather than dispassionate, policy-based assessment, simply adding more of it will not improve the quality or speed of decision-making. My own experience has led me to conclude that, especially on major schemes, public sector heritage bodies are far more likely to overcook heritage issues than applicants are to undercook it. Too often, ideology trumps calculated assessment.
A functioning system relies on experienced professionals, both inside and outside local planning authorities, being able to say with confidence where the line sits in rational, arguable terms. In a dysfunctional system, where fear of change outweighs rational assessment, heritage becomes a proxy for uncertainty: officers defer decisions, committees react, and reasoning thins.
What next?
Planning reform will not change this picture. New NPPF policies, altered consultation thresholds or changes to statutory consultees, like the Gardens Trust, will not, in themselves, shift how heritage advice is framed or received.
The answer lies not simply in padding out local authorities with more heritage specialists, which may compound the issue, but first and foremost in training case officers to understand and apply the planning balance with confidence; to challenge views of consultees where they diverge significantly from professional submissions, not just vice versa; and to have the wherewithal to argue contrary views to committees in non-deferential terms.
“The answer lies not simply in padding out local authorities with more heritage specialists, which may compound the issue, but first and foremost in training case officers to understand and apply the planning balance with confidence”.
A less rarefied atmosphere for heritage specialists would also help, with training and guidance from professional bodies and Historic England stressing the need for a positive attitude to facilitating change, not to fear it.
How developers should adapt
The mistake is to treat heritage as a last-minute, regulatory hurdle. In reality, it is one based on careful assessment and even more careful argument. The most effective schemes are already adapting in five clear ways.
1. Bringing heritage forward: Early, scheme-shaping heritage analysis gives heritage consultants a strategy path, gives officers confidence and reduces delays.
2. Focusing on significance (including contributory setting): Clear, intelligible assessments anchored immovably on impacts to identified aspects of significance strengthen the base for advocacy.
3. Engaging consultants who will advocate: Instead of just a report provider, in this climate, a consultant must be a constant and robust advocate against unreasonable local planning authority/consultee positions.
4. Strengthening the balance with public benefits: Focusing on heritage benefits rather than harms anchors schemes in a solid, arguable position.
5. Planning for appeal resilience: Resilience is not in making every concession to heritage officers or consultees, but in ensuring that the assessment base is dispassionate and clearly evidenced.
A final reframing
Developers who recognise this and respond accordingly will move faster, not slower, regardless of national policy changes. Approached confidently and strategically, the tools to push back on resistance and secure consent are readily at hand.
