Permission in principle: Permission to land?


Permission in principle is a key reform to the Housing and Planning Act 2016, but how will it speed up the planning process? Chris Kendall, Digital Strategy Lead at Idox delves into the thinking behind the idea

With the Housing and Planning Act 2016 passed into law on May 12, 2016, it’s timely to look at one of the key planning reforms to the act. ‘Permission in principle’ promotes the idea that developers will be able to secure ‘automatic consent’ for certain sites – where the principal of development has already been established. The government’s aim is to ensure one million desperately needed homes are built in the UK by 2020 by speeding up the planning process to make it more streamlined and efficient.

First Steps

The current submission and permission granting system is seen as a hindrance to the need to get Britain building new dwellings. At present, developers have to provide a large amount of information to local authorities from the outset. This is even the case to gain outline planning permission. The process is time-consuming, one that could potentially be without reward and be a waste of valuable resources.

The 2016 Act has made the amendment of introducing the new ‘Permission in Principle’ process. The thinking behind the legislation is to separate the process into two distinct components. One is the ‘in principle’ component, which is such factors as the land’s current use, its location and the amount of development to be allowed on the site. The second part of the process is the technical and aesthetic details of the project, such as what the buildings will look like. If the first part is agreed to be viable ‘in principal’, then it will encourage developers to pursue the matter further, with a favourable outcome a possibility. The choice about where to grant permission in principle will be down to local authorities, so it’ll be where development is considered to be locally acceptable and in line with the requirements of the National Planning Policy Framework, Local Plan policy and with existing requirements relating to national heritage.

It’s a Matter of Principle

The act allows ‘permission in principle’ to be granted where local authorities and neighbourhood groups choose to allocate housing-led development in neighbourhood plans or to identify them on Brownfield Registers. The new legislation will not replace the need to look at developments against the National Planning Policy Framework and local planning policy. Once granted, the technical details stage can allow for the assessment of detailed design and other factors, such as infrastructure, to be scrutinised. There’s no foregone conclusion that the ‘permission in principle’ will be automatically granted and refusal could still be an outcome, once the technicalities are explored and discussed.  But industry figures are initially encouraged by the new legislation. Andrew Dixon, Policy Officer at the Federation of Master Builders commented:

“Taking land out of the equation means the developers don’t need to invest money before they know that the site is highly likely to get permission. A huge investment in the pre-application is needed just to get an outline permission. If a site is allocated in a local plan, it seems ridiculous that you would need to get outline planning permission to establish the principal of the development. This should de-risk the process on these small sites, by allowing people to provide very little upfront information.”

It’s hoped that permission in principle will help to deliver more new homes by providing applicants and speculators with greater certainty from the outset that the land they are proposing for development is suitable for housing development. It will also encourage investment into housing development more swiftly and speed the process from both sides’ point of view. The decision on permission in principle only has to be granted once. After a decision has been made that the land is suitable for housing development, the applicants do not need to seek further assurances at a later date.

Passed in principle

The aim of the new legislation is to enable permission in principle to be granted for housing-led development when parcels of land are allocated in Local Plans, Neighbourhood Plans, or identified on Brownfield Registers. Developers will be able to apply for permission in principle directly to their local authority for development on small sites only. A sub-clause stipulates that the permission in principle rules cannot be used for development involving fracking (termed in the legislation ‘the winning and working of minerals’).

This is a key change to existing planning law. The new permission in principle legislation is needed to separate out the two processes mentioned above (the principle and greater detail) and also to enable permission in principle to be granted on sites chosen and allocated by local authorities within their local plans, or to enable applicants to apply directly to their local authority for permission. This is not possible via the existing legislation. In the same way that planning proposals and developments are currently subject to ensuring that the heritage aspect of local areas is retained, the technical details consent will still ensure appropriate protection of the historic environment.

The aim of permission in principle is to streamline the early-stage planning process without losing its robustness and integrity.  This reflects the same ethos as iApply, the innovative technology from Idox, which aims to further facilitate the planning and building control process. Its goal is to make the interaction between LA’s planning and building control procedures and those developing and building projects more fluid and flexible.

  1. One minor issue – if developers no longer need to pay for the studies necessary to ensure that development of the type, scale, and layout proposed is appropriate to the site, then who does? In this case, it is the local planning authority who have to do that detailed work through the preparation of the local plan. You might say “surely this is already done” but of course a local plan allocation is not, as yet a “permission in principle” and therefore the detail of assessment is significantly less. We will see LPAs having to carry out full ecological surveys, topographical surveys, transport and access assessments (and possibly designs), archaeological and heritage surveys, etc – all the requirements for an outline consent mentioned in the article and which are apparently so onerous. If anyone thinks that Local Plans are taking too long already, then try to imagine how long they will take under a PiP regime (particularly in a period of annual reductions in local authority expenditure).

    Of course the alternative is just to ignore all of these issues, and give permission without knowing the full extent of biodiversity, heritage, transport and other impacts. Fair enough, but let’s be honest if that is what we are proposing.
