Waste capacity and borough apportionment in London

London boroughs are each given a share of the capital's waste to plan for, and Policy SI 8 of the London Plan 2021 is where that apportionment and the protection of existing waste sites sit. If your site is a safeguarded waste site, or an operating waste facility, the policy starting point is refusal unless you provide compensatory capacity elsewhere. That requirement catches a lot of industrial redevelopment schemes late in the process, when the site history finally surfaces.

The underlying aim is net self-sufficiency: London managing its own waste within its own boundary rather than exporting it. Boroughs deliver that through land allocations in their local plans, and applicants meet it by not removing capacity without replacing it.

How waste capacity is apportioned to boroughs

The London Plan sets out borough-level apportionment targets in tonnes, stepped across future years, covering household and commercial or industrial waste. Each borough is expected to identify sufficient land in its local plan to manage its apportioned tonnage, either alone or jointly with neighbouring boroughs through a waste planning group.

That apportionment is a plan-making obligation rather than a test applied to each application. It still matters to applicants, because a borough that is behind on its apportionment will defend every remaining waste site hard, and will take a narrow view of what counts as adequate compensation.

Check two things before buying or designing. Whether the site is identified as a safeguarded waste site in the borough's local plan or waste policies, and whether the borough's apportionment is being met. Both come from the adopted plan and its evidence base.

Safeguarded waste sites and the no net loss rule

Existing waste sites are safeguarded. Policy SI 8 expects proposals that would result in the loss of waste management capacity to be refused unless compensatory capacity is provided, and the benchmark is the maximum throughput of the existing site rather than its current trading level.

That distinction does the damage. A transfer station running at half capacity because of a soft market still has to be replaced at its permitted or operational maximum. Pull the environmental permit and the planning history, because the permitted tonnage in the environmental permit is where the number usually comes from.

Safeguarding also attaches to land allocated for waste use even where no facility is operating. A cleared yard with a waste allocation is treated the same way as a working facility.

What a scheme on a waste site has to show

The application needs to answer four questions in order, and the answers belong in the planning statement rather than scattered through technical appendices.

1. Is the site a safeguarded waste site, or allocated for waste, in the development plan?
2. What is the existing capacity, measured as maximum throughput, with the permit and planning history to evidence it?
3. Where will compensatory capacity be provided, and is it secured?
4. Does the replacement capacity handle the same waste streams at an equivalent point in the hierarchy?

The fourth question is the one most often ducked. Replacing a mixed municipal transfer station with a specialist recycling facility that takes a narrow waste stream is not equivalent capacity, however impressive the tonnage looks. The borough and the Greater London Authority will both say so.

Where a site is truly redundant and no compensatory capacity is offered, the case has to be evidenced rather than asserted: marketing evidence, permit surrender, the borough's own apportionment position, and the contribution of alternative sites. That is a harder argument than most applicants expect, and it has clear parallels with protecting industrial land in London under the no net loss and SIL policy.

Compensatory provision and where it can go

Compensatory capacity should be provided within London. Preference runs to the same borough, then to the waste planning group, then elsewhere in the capital. Capacity provided outside London undermines the self-sufficiency aim and will be resisted.

Securing it is the practical difficulty. Options in use include a planning obligation tying the redevelopment to the delivery of replacement capacity at a named site, a parallel application for the replacement facility determined alongside the scheme, and a Grampian style condition preventing implementation until the replacement is operational.

Developers dislike all three because they couple the scheme's programme to a facility they often do not control. Starting the conversation with the borough's waste officer at pre-application, well before the planning application, is the only way to make the mechanism work. Sites within an Opportunity Area allocation sometimes have a strategic answer already identified in the framework document, which is worth checking first.

Construction and demolition waste expectations

Separately from capacity, London schemes are expected to deal with the waste they generate. The London Plan sets high recycling and recovery expectations for construction and demolition waste and for excavation material, with beneficial use rather than landfill as the default.

For a referable scheme, a circular economy statement is required, setting out how materials will be retained, reused and recycled, with a bill of materials and targets. Even below the referable threshold, boroughs commonly ask for a site waste management plan by condition despite the regulations requiring them having been revoked.

Excavation material deserves early attention on sites with basements. Moving spoil off site is expensive and carbon intensive, and a scheme that can reuse material in landscaping or retain it on site has a better answer at both ends, something the design-led approach in optimising site capacity under policy D3 tends to flush out early.

Operational waste storage in a new building

The everyday version of waste policy is the bin store, and it fails more applications at officer level than apportionment ever does.

Boroughs publish waste storage standards in their local plans or supplementary planning documents, covering container numbers, separation of recyclable streams, the maximum carry distance from a dwelling to the store, and the maximum drag distance from the store to the collection point. Refuse vehicle swept path analysis is normally expected where collection happens on site.

Design the store as a room with ventilation, drainage, a washable surface and lighting rather than a cupboard added at the end. Mixed use schemes need separate commercial and residential provision, because the collection arrangements and the contractors differ.

Evidencing the position in the application

Pull the evidence together in one place. The development plan designation with the policy reference, the site's permit and planning history, the throughput calculation, the compensatory proposal and its delivery mechanism, then the construction waste and operational storage strategies.

Councils will check the designation themselves, so stating it accurately at the outset builds credibility for everything that follows. Where the site is not safeguarded, say so plainly and show the plan extract rather than staying silent and inviting the question.

A clear, well sourced waste chapter rarely wins an application on its own. A missing one, on a safeguarded site, will lose it. For borough specific rules that sit alongside this, the interaction with Article 4 directions in London is worth checking at the same time, since both turn on designations recorded in the local plan rather than anything visible on site.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
