Housemark’s latest monthly Pulse survey, based on performance data from 132 social landlords, found new ASB cases increased by 24.3% in July, following a 32% rise between May and June.

Housemark’s analysis of ASB figures and Met Office temperature data found strong evidence of a seasonal relationship between warmer weather and increased ASB activity. The research found ASB case volumes are typically around 50% higher during summer than winter.

The findings suggest longer periods of warmer weather could extend traditional ASB peaks and create longer periods of elevated demand.

Alongside rising neighbourhood pressures, average re-let times rose to 50.5 days in July, exceeding 50days for the first time since March, despite vacancy rates continuing to improve. The median vacancy rate fell by 8.5% month-on-month to 0.53%.

The survey also highlighted the impact of repairs performance on customer satisfaction. While the median proportion of responsive repairs outstanding fell by 3.3% to 5.5% in July, around one in five landlords continued to report work in progress levels above 10%. Organisations with sustained backlogs above this level reported transactional repairs satisfaction scores 1.6 percentage points below the sector median of 89%.

Jonathan Cox, chief data officer at Housemark, said: “As landlords navigate a rapidly changing operating environment, data is helping us understand emerging pressures before they become long-term challenges. The relationship between warmer weather and anti-social behaviour is becoming increasingly evident and raises important questions about how services are planned and resourced in the future.

“At the same time, landlords continue to balance competing operational demands, including reducing void periods, maintaining repairs performance and preparing for significant regulatory change. Understanding these trends is essential if organisations are to deliver efficient services and positive outcomes for residents.”

Additional findings from the August Pulse survey include:

• Customer contact received through digital channels increased by 7.2% month-on-month to 39.9%.
• Median satisfaction with landlord services increased by 3.5% month-on-month to 77.2%.
• Median compliance with Awaab’s Law emergency hazard response times (in England) remained at 98.0%.
