This paper by Cecilia Eve, Director and President of Young European Movement UK explores the crisis of hidden homelessness in the UK, highlighting systemic failures and the urgent need for reform. Housing shortages, rising costs, and insufficient social housing have left a quarter of a million people, including 54% children, in temporary accommodation. Despite its name, such accommodation is often far from temporary, with families enduring years in substandard living conditions, including damp, mould, and overcrowding, often without basic amenities like cooking facilities or internet access. The cycle of debt, exacerbated by high living costs, stagnant wages, and inadequate welfare, perpetuates housing insecurity. Women are disproportionately affected due to gender pay gaps, domestic abuse, and lack of affordable childcare. Charities like the Shared Health Foundation reveal that temporary accommodation often traps individuals, worsening their financial and mental health. This paper calls for the UK government, particularly under the new Labour administration, to prioritize affordable housing, tackle the private rental sector, and address the broader socioeconomic drivers of homelessness.
