CIH response to MHCLG consultation on planning powers for mayors in England

Introduction

We broadly welcome the proposed expansion of planning powers for elected mayors across England, to align their powers and responsibilities with those available to the Mayor of London. These mayoral planning powers will be important tools to support development of new homes where they are needed and, used in conjunction with the Spatial Development Strategies (SDSs) that are now being developed by strategic authorities across England, will help to coordinate delivery of housing and infrastructure. However, it is important that mayoral planning powers are carefully designed to support housing growth and to ensure mayors and strategic authorities work effectively with local authorities.

Our main points in response to this consultation are:

  • Mayors should only receive call-in powers once a Spatial Development Strategy is in place. 

The consultation proposes that any application for a residential development of more than 150 homes could be categorised as having potential strategic importance (PSI) and called in by a mayor. This means that the planning decision would be taken out of the hands of the relevant local authority and instead made by the mayor. We believe this power should only be provided when an SDS covering the relevant area has been adopted. This would align closely with the powers available to the mayor in London, where a proposed development must be considered to have a significant impact on the London Plan for it to be called in. We also believe this measure would incentivise timely production and adoption of Spatial Development Strategies.

  • Mayoral strategic authorities will need additional support to build planning capacity.

Planning capacity varies significantly between different mayoral strategic authorities (MSAs). While some established, larger MSAs have specific planning teams, others are reliant on secondments or collaboration with local authorities. If mayoral planning powers are to be used effectively to support housing growth, government will need to support MSAs to build capacity.

  • Mayoral development orders (MDOs) can be effective tools to support housing delivery.

We broadly agree with the proposed approach to mayoral development orders, which provide upfront grant of planning permission by a mayor for development on a particular site. We recommend that local housing associations should be included as statutory consultees in the pre-MDO consultation process, to facilitate early consultations with potential delivery partners and ensure, where it is proposed, that the right mix of social housing is provided through MDOs.

  • Mayoral Community Infrastructure Levies (MCILs) offer significant potential to support infrastructure – but must be designed carefully to meet local needs.

In London, the MCIL has been used effectively to help fund infrastructure such as the Elizabeth Line. We see significant potential for similar arrangements across England, but care must be taken to ensure they are set at the right level and work in partnership with CILs and Section 106 (S106) agreements at the local level. The design of any MCIL should reflect and complement the ongoing review and reforms of the S106 process to deliver a simpler, more transparent and more resilient system of developer contributions for infrastructure. 

Answers to individual questions

1. Do you agree with the proposed PSI application categories for areas outside London, as set out in Annex A?

Partially disagree.

We disagree with the new proposed threshold for residential applications to be categorised as having potential strategic importance (PSI). The consultation document proposes that any application for a development of more than 150 homes could be categorised as PSI and therefore be called in by a mayor. We believe that, without a Spatial Development Strategy (SDS) in place, this threshold is too low and potentially draws a large number of applications into the call-in process.

While this threshold has been in place in London for a number of years, a proposed development must be considered to have a significant impact on the implementation of the London Plan to be classified as a PSI. The proposal that these powers should be available to mayors outside London before an SDS is in place means the threshold for call-in would be lower in Mayoral Strategic Authorities (MSAs) across the rest of England than in London. The English Devolution White Paper proposed that mayors will have access to development management powers allowing them to intervene in planning applications of potential strategic importance only after an SDS is adopted. We believe this is the right approach to ensure that call-in powers are used constructively and proportionately, and are accompanied by the clear accountability mechanisms that an SDS provides. We also believe that this would provide an incentive for MSAs to develop their SDS in a timely fashion so they can unlock the mayoral planning powers that could help them deliver on their strategic objectives.

In addition, we have some concerns about the capacity of MSAs outside of London to assess the number of applications that would be received following call-in under the current proposed threshold. The Greater London Authority has a large and experienced planning and housing team to assess planning matters. In contrast, capacity differs significantly between different MSAs, with some newer and smaller MSAs having no designated planning teams at all. This could cause significant delays to planning processes and/or the development of new homes. We encourage the government to support MSAs to develop housing and planning capacity to ensure these new powers can be used effectively to deliver social and affordable homes. 

3. Should mayors outside of London be able to call-in Category 3J (50 homes or more) applications where local planning authorities are minded to refuse?

No.

We consider that applications for development of this size should not usually be classed as strategically important and therefore should not fallwithin the scope of the call-in process. However, mayors in London and outside London should be able to call in Category 3J applications (50 homes or more) where local planning authorities are minded to refuse schemes that deliver 60% or more affordable housing. In line with call-in powers more broadly, these should only be granted to mayors when an SDS is in place. 

4. Do you agree that the scope of powers to intervene in relation to PSI applications should expand as an SDS is progressed?

Partially agree.

As stated in our answer to question 1, we believe the power for mayors to classify an application as PSI should only apply when an SDS is in place. 

5. Do you agree where a Spatial Development Strategy is not yet adopted, a decision by a mayor to either direct refusal of, or call-in, a PSI application will need to be justified in respect of growth?

Partially disagree.

We believe refusal/call-in powers should only be provided to mayors when an SDS is in place. The proposal as currently written is clearly designed to provide mayors with powers to unblock stalled developments. However, there is a risk that these powers could be used by mayors to refuse applications supported by local authorities. Providing call-in and refusal powers to mayors only after an SDS is adopted would reduce the risk of mayoral planning powers being used to block developments that would otherwise go ahead. Providing these powers only after SDS adoption would also incentivise the production of ambitious and policy-compliant SDSs. 

6. Do you agree with the proposed criteria for mayors to use their PSI application powers following adoption of a Spatial Development Strategy?

Strongly agree.

The consultation document states that following adoption of an SDS, mayors will be able to direct refusal or call-in an application if it is contrary to good strategic planning in the area and/or it would have significant implications for the implementation of the SDS. We support the principle of enhanced mayoral planning powers being provided only once an SDS has been adopted. We believe this will encourage the development of evidence-led SDSs that reflect the long-term needs and aspirations of the areas they cover, and provide scope to align social and affordable housing delivery with action to address climate change and its impacts, and to promote economic growth and employment. This proposed change would align the planning powers available to mayors across England with those available to the mayor of London. 

8. Do you agree to the approach to exclude centrally led Urban Development Corporations or New Town Development Corporations from a mayor's powers to direct refusal and call-in PSI applications?

Partially agree.

We believe there should be some distinction in how Urban Development Corporations (UDCs) and New Town Development Corporations (NTDCs) are treated in respect of the proposed approach to mayoral planning powers. UDCs that fall within aan MSA area should be aligned with the priorities and objectives of elected leaders in those areas and, where possible, should be designated as Mayoral Development Corporations to enable direct control and accountability. However, we agree that new towns are a national strategic priority and that NTDCs, when developing genuinely new settlements (as opposed to urban extensions or regeneration schemes) should sit outside the proposed PSI process for mayors. NTDCs should be established as long-term delivery vehicles.  Whilst outside the scope of this consultation, further work is required to ensure NTDCs can effectively deliver on the government’s new towns agenda. 

12. Do you agree with the proposed approach to preparing a Mayoral Development Order?

Strongly agree.

The proposed process aligns with that currently in place for preparation of Local Development Orders – it is sensible to align these processes. 

13. Do you agree with the proposed approach to publicity and consultation of a Mayoral Development Order?

Partially agree.

We broadly agree with the proposed approach to consultation. However, we recommend that, if a MDO covers development including social housing, that local housing associations should be included as statutory consultees. We believe this will help to facilitate early consultations with potential delivery partners and ensure, where it is proposed, that the right mix of social housing is provided through MDOs. This consultation could be delivered through a housing partnership, where one is in place. 

17. To what extent, and in what ways, could evidence and analysis used to prepare a Spatial Development Strategy (SDS) inform work to prepare a CIL charging schedule?

We agree with the proposal that an SDS should be in place before a mayoral Community Infrastructure Levy [CM2.1][TA2.2](MCIL) can be introduced. 

19. How might the requirements for updating a Mayoral CIL charging schedule best ensure Mayors of strategic authorities can keep rates reflective of market conditions?

Any MCIL should be reviewed regularly to ensure it does not negatively impact the viability of development. In addition, MSAs should work with local authorities to ensure CIL is delivered at the right level. For example, if a local authority CIL is already in place, MSAs should be encouraged to work with the relevant local authority to explore whether a local or MCIL is the right mechanism. CIL and Section 106 (S106) agreements are necessary to ensure that infrastructure is in place to support existing and new communities through new developments. Earlier this year, the Housing and Planning Minister set out plans to comprehensively review and reform the S106 system to ensure it is simpler, more transparent and more resilient, and progress has been made on this in recent months. We recommend that the design of any CIL programmes should reflect and complement this work so that all developers have a clear idea of their role in contributing to supporting infrastructure. 

21. Are there further conditions or requirements (i.e. beyond those which already exist, and those proposed in this consultation) that mayors should need to fulfil before they can charge MCIL?

An SDS should set out clear infrastructure priorities for the area, including transport, energy and water requirements. In setting out the MCIL, it should be clear how the CIL will fund this infrastructure and how this will support future housing growth. 

22. Do you agree that MCIL outside of London should be capable of funding a broader range of strategic infrastructure than the current model in London (which funds strategic transport infrastructure only)?

Strongly agree.

We agree with the principle of providing more flexibility for mayors to deliver strategic infrastructure funded by MCILs and believe an SDS is the right mechanism to lay out these priorities. 

25. How can the collection of MCIL work simply and effectively in all circumstances, including when the local tier authority does not charge its own CIL?

Collection of the MCIL in London is carried out by local authorities and pooled. We believe this model works well and should be replicated outside London.
