The two tier planning system in Northern Ireland

The planning system northern ireland operates is two tier. Eleven councils determine most applications, the Department for Infrastructure determines the largest and most strategic ones, and the category your scheme falls into decides who decides it, what consultation you must carry out first, and where an appeal goes.

Everything below applies to Northern Ireland alone. There is no National Planning Policy Framework here, no Community Infrastructure Levy, and appeals do not go to the Planning Inspectorate. A document drafted against English policy has to be rewritten against the Northern Ireland framework before it is submitted.

Councils and the Department for Infrastructure

Most planning functions transferred from central government to the eleven district councils on 1 April 2015 under the Planning Act (Northern Ireland) 2011. That transfer is recent enough that older guidance and older habits still circulate.

Councils now handle development management for local and major applications, enforcement, and the preparation of their own local development plans. The Department for Infrastructure retains the top tier of applications, retains a call-in power allowing it to direct that an application be referred to it, and oversees the plan-making process through its role in adopting plans.

For a developer the practical consequence is that the decision-maker is not always obvious from the scale of the scheme, and the wrong assumption costs weeks at the validation stage.

The three categories of development

Development is categorised into three tiers, the top of which is described in the legislation as regionally significant, with major and local below it. The categories and their thresholds are set by the Planning (Development Management) Regulations (Northern Ireland) 2015, and the thresholds should be read from the schedule to those Regulations rather than from a summary, because they differ by class of development.

The top tier is determined by the Department rather than the council. It covers schemes of substantial regional importance, and the Department can also direct that a major application be moved into that tier.

Major development is determined by the council but carries additional procedural requirements, principally mandatory pre-application community consultation.

Local development is everything else, and it is the great majority of applications, including householder work, small commercial schemes and most changes of use.

Pre-application community consultation for major schemes

This is the requirement that catches developers used to the English system, where community engagement before an application is good practice rather than a statutory step.

For major development you must serve a Proposal of Application Notice on the council, setting out the proposal and how you intend to consult, and then wait a minimum period of twelve weeks before the application can be submitted. During that period you have to carry out the consultation, including at least one public event, and notify the bodies the council specifies.

The application must then be accompanied by a pre-application community consultation report recording what you did, who responded and what changed as a result. An application submitted before the twelve weeks have run is invalid, and a report that records an event nobody could attend invites a challenge to validation.

Build the twelve weeks into the programme at the point you acquire the site, not at the point you finalise the drawings.

Local development plans and what applies until they arrive

Each council is preparing a local development plan in two parts, a plan strategy followed by a local policies plan, and the councils are at different stages. Until a plan is adopted, decisions rely on retained regional policy.

That retained policy is the Strategic Planning Policy Statement for Northern Ireland, together with those elements of the earlier planning policy statements that remain in force, and the Regional Development Strategy. Which of the older statements survive depends on the subject matter, and our note on retained policy and the Strategic Planning Policy Statement sets out how the two layers interact.

So the first question on any Northern Ireland site is which plan stage the council has reached. A scheme in a council with an adopted plan strategy is assessed differently from the identical scheme in a council still relying on retained policy, and the weight arguments are different too.

Countryside development is the clearest example of policy that behaves nothing like its English equivalent, and our note on dwellings in the countryside in Northern Ireland covers the tests that apply.

Determination periods and performance

Councils report against processing targets rather than the statutory eight and thirteen week periods an English practitioner will expect, with separate targets for major and local applications published by the Department.

Two practical points follow. Target times are averages across a council's caseload, so they are a planning assumption rather than a commitment on your application. And because the targets are measured on the council's performance, a scheme that needs extended negotiation may be encouraged towards withdrawal and resubmission rather than a long determination.

Ask the council at pre-application what its current processing position is on applications of your type, and ask whether it uses any form of agreed timetable.

One honest uncertainty. Performance reporting and target times have moved more than once since functions transferred, so treat any figure you find in a secondary source as out of date and ask the council directly.

Statutory consultees you will not recognise

The consultee list is different, and identifying it early avoids the most common cause of delay.

• The Department of Agriculture, Environment and Rural Affairs, including its environment agency functions, on ecology, water and pollution matters.
• The Rivers Agency function within that department on flooding and drainage.
• Departmental roads functions on access, parking and highway matters.
• Northern Ireland Water on water supply, sewerage capacity and connections.
• The Historic Environment Division on listed buildings, scheduled monuments and archaeology.
• Councils' own environmental health teams on noise, odour and contaminated land.

Sewerage capacity deserves particular attention. Capacity constraints in the wastewater network have blocked development in parts of Northern Ireland, and a capacity check with the water undertaker at the feasibility stage is worth more than any other early enquiry. Where capacity is not available, the options are a developer-funded solution, a phased release tied to network investment, or a different site, and each of those changes the appraisal rather than the drawings.

Ecology is the other area where the framework diverges. Northern Ireland has its own habitats and species legislation, its own designated site series including Areas of Special Scientific Interest, and its own licensing arrangements, so an ecologist who works only in England will need to check the licensing route before committing to a survey programme. The survey seasons themselves are broadly the same, which means the programme risk is the same too.

Contributions, appeals and the right route

There is no Community Infrastructure Levy in Northern Ireland. Developer contributions are secured through planning agreements under section 76 of the 2011 Act, and practice on what authorities seek is less standardised than in England, as our note on developer contributions in Northern Ireland explains.

Appeals go to the Planning Appeals Commission, an independent body with its own procedures, rather than to the Planning Inspectorate. The Commission also handles enforcement appeals and other statutory references, and its procedures and timescales are its own, as set out in our note on planning appeals to the Planning Appeals Commission.

Choosing the route comes down to four questions. Which of the three categories does the development fall into under the 2015 Regulations. Has the council adopted a plan strategy. Does the wastewater network have capacity. And is a Proposal of Application Notice needed, with the twelve weeks that follow. Answer those before you commission drawings.

PlanScope drafts the supporting documents an application needs and you can browse the report types to see the scope of each, though the drafting is grounded in English policy and a Northern Ireland reviewer must replace the policy references before anything is submitted.

This is general guidance, not legal advice; check the position with the council or a qualified professional before relying on it. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.
