The Institute for Public Policy Research (IPPR), a leading think tank, has presented a detailed concept for a national rent stabilisation system. The aim of this proposal is to moderate rent developments while addressing the complex challenges of housing supply and investment activity in the property market.
The model developed by the think tank, known as the 'Double-Lock' system, proposes linking rent increases to two key economic indicators: wage growth and the Consumer Price Index (CPI). This dual cap is intended to apply both during ongoing tenancies and for new lettings of properties. The intention is to ensure fair and predictable rent developments for tenants without completely undermining incentives for investment and the creation of new housing.
Details of the 'Double-Lock' model
The proposed system would therefore set a maximum increase in rents that should not exceed average wage growth or the general inflation rate. This method is intended to ensure that rents remain in line with economic development and tenants' purchasing power. By considering both factors, an attempt is made to strike a balance between the interests of tenants and the need for a sustainable property economy. The IPPR emphasises that such a system could help to reduce volatility in the rental market and offer greater planning security for both tenants and landlords.
The implementation of such a system requires careful consideration of the potential effects on the supply of rental housing. Critics of rent caps often argue that they make investment in housing construction less attractive and could therefore reduce the available supply. The IPPR addresses these concerns by stating that the 'Double-Lock' model has been designed to stabilise rents while simultaneously preserving incentives for investment and the maintenance of existing properties.
Background and objectives
The necessity of rent stabilisation is being discussed against the backdrop of rising living costs and tight housing markets. Many households, particularly in urban centres, face significant rent increases that often exceed wage growth. The IPPR views its proposal as a way to alleviate this pressure while creating a foundation for long-term stable and fair housing conditions.
- —Limiting rent increases during the contract term.
- —Applying the limitation also to new lettings.
- —Linking rent adjustments to wage growth and the Consumer Price Index.
- —The goal is to promote stability and predictability in the rental market.
