The Economics of Community Forensic Support

When we talk about the cost of running mental health services, we’re usually thinking of one thing: the number on the invoice. What does a bed cost? What does a support worker cost? What does the programme cost per person, per year?

Budget constraints are real. We know that Commissioners have to make hard choices with finite money, and a number on a spreadsheet is easier to compare than a life rebuilt. But when it comes to forensic community support, that narrow version of cost misses almost everything that matters.

At Bridge Support, we’ve spent years running Tilt, our forensic mental health service for people leaving secure hospitals and prisons. If you look at numbers carefully, you’ll see they tell a very different story to the one most people expect.

The Number Nobody Argues With

Reoffending is expensive… in a very literal sense. The Ministry of Justice puts the annual cost of reoffending in England and Wales at somewhere around £18 billion, once you add up policing, courts, prisons, probation, and victim suffering. A 10% reduction in that figure would be worth close to £1.8 billion a year, and that’s before anyone has mentioned a single person’s actual recovery.

Over the last five years, 1.58% of people who have been through Tilt have reoffended. Set that next to what usually happens when someone with serious mental illness leaves a secure setting with nowhere stable to go, and you start to see why the framing matters. One path keeps unravelling inside an institution. The other path gives someone a decent shot at a life outside one.

Stability Is Not a Soft Outcome

I’ve sat in enough commissioning meetings to know that “stability” can sound like a nice-to-have, something said to appear compassionate next to the harder figures that actually decide budgets.

But stability is the mechanism. Someone with consistent housing, a support worker who knows them well, and a daily routine that they can count on is someone whose risk profile genuinely changes for the better. Their mental health stabilises, their relationships get a chance to recover. Their contact with services shifts from crisis management to something closer to maintenance.

Over 64% of the people who go through Tilt move on to independent or less supported accommodation. Obviously this is amazing for the individual but it also means the system stops paying for the most expensive tier of care, because someone has been supported well enough to no longer need it.

What a Secure Bed Actually Costs

Here’s what rarely gets addressed. A secure hospital bed or a return to prison isn’t a neutral alternative to community support. In fact, both of these services costs considerably more, and it offers a worse chance of the person actually getting better.

When someone reoffends and goes back into custody, or relapses and is readmitted to a secure ward, the bill doesn’t stop at the bed. There’s the court time that got them there, the assessments, the risk management, and the added pressure on NHS and prison capacity that’s already stretched thin. None of that shows up in the numbers when someone compares “cost per support worker hour” on a spreadsheet because the costs don’t belong to one organisation. They are shared between different services.

If you measure only the input, community forensic support looks like the pricier option. Measure what it prevents and the picture flips completely.

Continuity Has a Price Tag Too, Just Not the One People Expect

One of the subtle risks in this sector is short-term commissioning. Contracts running twelve or eighteen months, reviewed and re-tendered before a service has had any real chance to prove how much money it can actually save given time. Honestly, this is so frustrating for most services. It’s actively counterproductive for forensic support.

Recovery from serious mental illness, especially alongside a criminal justice history, so rarely moves in a straight line and rarely moves quickly. The relationship between a service user and their support takes time to establish, and it’s often the biggest factor in whether someone stays engaged or drifts back towards crisis. If we keep interrupting the continuity of care partway through, the recovery journey has to start again somewhere else, with people who don’t yet know that person’s history. That isn’t a saving but rather a delay dressed up as one.

Value, here, isn’t the cheapest unit cost. It’s the support that’s still there in year three, still knows the person, and hasn’t had to rebuild trust from zero because a contract changed hands.

What We Mean by Value

When I talk about value at Bridge, I don’t mean squeezing more out for less. I mean understanding what’s actually being paid for when community forensic support gets funded: fewer people cycling back through the most expensive parts of the justice and health systems, and fewer recoveries that have to restart from scratch because the contract started again.

That’s a harder case to make in a single line on a budget spreadsheet than “cost per hour.” It’s also the honest version of the accounting, and it’s the one commissioners, and the public deserve to see.
