The Hidden Mental Health Service: Rising mental health casework in MPs’ offices

MPs’ offices are now playing a vital role in supporting people affected by mental health problems.

Our latest research shows that parliamentary staff are increasingly helping constituents with mental health needs, often without the right training or resources to handle complex and sometimes life-threatening situations. 

We surveyed staff from 120 MPs’ offices. The findings are clear: mental health casework is rising to unsustainable levels.

Nearly half of those we spoke to receive mental health-related correspondence every day, and 93% deal with it at least once a week.

Over half (54%) have seen an increase in mental health casework since starting their role, and none reported a decrease.

Why mental health support is increasingly falling to MPs' Offices

Many people turn to their MP when they can’t access NHS services, need help with welfare, or are worried about a family member’s mental health. MPs' staff often speak to people in crisis, including those experiencing suicidal thoughts, concerns about self-harm, or fears for loved ones. Our findings suggest that MPs’ offices are stepping in to fill the gaps left by an overstretched system.

The impact of mental health crisis casework on parliamentary staff

This work takes a real toll on staff. More than half (53%) told us that dealing with mental health casework has had a negative effect on their own wellbeing. One in five have even thought about leaving their job because of the emotional strain. Despite this, most staff feel they don’t have enough training to manage these situations safely and effectively.

  • People are really more unwell. They’re not getting the help, they’re not getting early intervention, they’re not getting the right support at the right time.

Recommendations to improve mental health casework management

Rethink Mental Illness is calling for:

  • Mandatory mental health training for all new parliamentary staff
  • Dedicated emotional support services for employees handling difficult cases
  • Clear protocols for responding to constituents experiencing suicidal thoughts

We’re also urging the government to:

  • Cut waiting times for mental health support
  • Strengthen community mental health services
  • Expand access to innovative treatments
