Overcrowding Rules in Social Housing: Northern Ireland Guide

Living in social housing in Northern Ireland brings vital legal protections, especially regarding space and safety. Overcrowding can affect your family’s wellbeing and even give you priority on the housing waiting list. This guide explains when a home is officially classed as overcrowded, what standards apply, official forms, and practical steps for renters seeking help.

Understanding Overcrowding in Social Housing

The law in Northern Ireland sets specific rules about how many people can live in a home before it is classed as overcrowded. These are in place to protect renters, particularly families, from poor living conditions.

Legal Standards for Overcrowding

Under the Housing (Northern Ireland) Order 1981, a property is considered overcrowded if either of these conditions applies:

  • Room Standard: Too many people sleep in one room, with adults and children of different sexes (where children are over 10) having to share a room.
  • Space Standard: The total number of people exceeds the number that can be accommodated based on bedroom size and number.

Living rooms and bedrooms are counted as sleeping spaces. Kitchens and bathrooms are not.

How Many People Can Share?

The Housing Executive uses a simple guide:

  • Each person over 10 years old counts as one person
  • Children under 10 count as half a person
  • Certain rooms are measured—
    • Less than 50 sq.ft.: Not suitable as a sleeping space
    • 50–69 sq.ft.: 0.5 person
    • 70–89 sq.ft.: 1 person
    • 90–109 sq.ft.: 1.5 persons
    • 110 sq.ft. and over: 2 persons

Mixed-Sex Sharing Rules

  • No two persons of opposite sex (unless living together as partners) should have to sleep in the same room if one is over 10 years old

If these standards are breached, your home is classed as overcrowded by law and you have grounds to seek assistance.

What Should You Do If You Think Your Home is Overcrowded?

If you believe your social housing is overcrowded, you can take action to get support or request a move.

1. Contact the Northern Ireland Housing Executive (NIHE)

The NIHE manages most social housing and evaluates overcrowding complaints. You can start by contacting them directly to explain your situation.

2. Apply or Update Your Housing Application

When applying for social housing or updating your situation, mention if your current accommodation is overcrowded. Overcrowding may give you additional points on the waiting list, accelerating your move to a suitable home.

Relevant Official Forms

  • Social Housing Application (Form HMC1): Housing Application Form (HMC1)
    When to use: To apply for social housing or to notify the NIHE about changes, including overcrowding. Fill out and submit to your local housing office.
  • Change in Circumstances Notification: Change in Circumstances
    When to use: If your household size changes, update your details online or contact NIHE so they can reassess your housing need.

If you need specialist help, you can seek free advice from Housing Rights (see below), or if dissatisfied, a formal complaint can be made to the Housing Executive.

If your household size has changed recently (such as a new baby or a relative moving in), inform the NIHE promptly. This could increase your priority for a transfer or new housing.

What Happens After a Complaint?

The NIHE will usually arrange an inspection to assess overcrowding based on the legal standards above. If it is confirmed, they may offer temporary accommodation or adjust your transfer priority on the waiting list.

The Tribunal Handling Disputes

For disputes about social housing tenancies or condition issues, the Northern Ireland Courts and Tribunals Service (specifically, the County Court for housing matters) oversees applications and appeals related to housing decisions[1]. Disputes around landlord/tenant issues in private rentals are heard by the County Court or small claims, depending on the issue.
