The Real Cost of Manual TPI Responses

Every credit hire company deals with third-party insurer (TPI) correspondence. Letters challenging hire rates, questioning need, disputing liability, raising impecuniosity, citing case law. They arrive daily, and they all need a response. The question most businesses never stop to calculate is: what does responding to those letters actually cost?

1. The Hidden Time Tax

A typical TPI challenge letter raises multiple arguments. Responding properly means reading carefully, identifying each argument, researching relevant case law, checking that the authorities cited actually say what the insurer claims, and drafting a professional, accurate response.

For an experienced handler, this takes anywhere from 45 minutes to 2 hours per letter.

2. Putting a Number on It

Conservative assumptions: 30 TPI challenge letters per week, 75 minutes each. That's 37.5 hours of staff time per week.

At a fully loaded cost of £25 per hour, that is £937.50 per week, or roughly £48,750 per year, spent on a single operational task. For larger operations, the numbers scale quickly.

This does not account for delayed responses that weaken the claim position, inconsistent quality, or the opportunity cost of senior staff stuck on research.

3. The Quality Problem

When five people manually research and draft TPI responses, you get five different styles, five different levels of legal accuracy, and five different approaches to the same insurer argument. One handler cites Stevens v Equity Syndicate Management Ltd [2015] EWCA Civ 93; another cites nothing at all.

4. The Research Bottleneck

The most time-consuming part is research. Credit hire case law is highly specific. The principles around BHR, impecuniosity, mitigation, period, and rate are spread across dozens of authorities. Knowing which case to cite — and which not to — requires either deep expertise or significant research time.

This makes your most knowledgeable people the bottleneck for every complex letter.

5. What the Alternative Looks Like

A decision-support tool that analyses an insurer's letter, identifies each argument, maps it to relevant case law, and drafts a legally grounded response in minutes rather than hours fundamentally changes the economics.

Instead of 75 minutes per letter, the process takes 10 to 15 minutes — most of that spent reviewing and tailoring the output rather than researching from scratch. Every response draws from the same verified knowledge base.

6. The Operational Impact

For the mid-sized operation in our example, reducing average response time from 75 minutes to 15 minutes saves approximately 30 hours per week — the equivalent of a full-time member of staff redeployed to higher-value work.

Response quality becomes consistent. Every letter is grounded in verified case law. Turnaround times improve, which strengthens the claim position.

7. Questions Worth Asking

• How many hours per week does your team spend on TPI responses?
• What does that cost in salary, overheads, and opportunity?
• How consistent is the quality across your team?
• What would your team do with those hours if the bottleneck was removed?

The biggest cost in many credit hire operations is not technology or premises. It is time spent on work that should take minutes, not hours.
