How UK Law Firms & Solicitors Measure Cost Per Qualified Legal Enquiry
UK law firms measure cost per qualified legal enquiry by dividing attributable marketing costs by the number of enquiries that meet the firm's agreed criteria. It shows what you really pay for suitable opportunities, not just clicks or form fills. This guide explains the formula, what makes an enquiry qualified and how to track it.
What Is Cost Per Qualified Legal Enquiry?
- Enquiry: any call, form or message from a potential client.
- Lead: an enquiry your firm chooses to track and follow up.
- Qualified enquiry: a lead that meets your agreed criteria.
- New client: someone who instructs the firm.
Counting enquiries alone can mislead. Fifty enquiries sound great, but if most are in the wrong practice area, the real result is much smaller.
How to Calculate Cost Per Qualified Legal Enquiry
Cost per qualified enquiry = attributable marketing costs ÷ qualified enquiries
Include costs that generate enquiries, such as ad spend, agency fees, tools and relevant SEO or content work. Split shared costs using one consistent method, and always use the same reporting period.
| Item (illustrative only) | Figure |
|---|---|
| Attributable marketing costs | £2,000 |
| Total enquiries | 50 |
| Qualified enquiries | 20 |
| Cost per enquiry (£2,000 ÷ 50) | £40 |
| Cost per qualified enquiry (£2,000 ÷ 20) | £100 |
These figures are illustrative, not UK industry benchmarks.
What Makes a Legal Enquiry Qualified?
- It matches a practice area the firm offers.
- The matter fits your service and eligibility criteria.
- The contact details are genuine and usable.
- The person can be contacted and assessed.
Criteria differ by practice area. A conveyancing enquiry is screened differently from an employment one. Collect only what you need at enquiry stage and keep sensitive details for your formal intake process.
How UK Law Firms Track Enquiry Sources
- Google Ads: conversion tracking and tracking parameters on landing pages.
- Organic search and local SEO: organic traffic to enquiry pages and forms.
- Google Business Profile and phone calls: call tracking and direction requests.
- Forms, live chat, referrals and directories: tag each with a source.
No firm can attribute every enquiry perfectly. A client may see an ad, search later and then phone. Treat source data as a guide, and compare channels consistently. Strong local SEO and well-run Google and Meta ads management both depend on this clarity. Our guide to lead tracking software UK covers the setup, and lead attribution explains how credit is shared.
Which Metrics Should Solicitors Measure?
| Metric | Question it answers |
|---|---|
| Cost per enquiry | What does each raw enquiry cost? |
| Cost per qualified enquiry | What does each suitable enquiry cost? |
| Qualified enquiry rate | How many enquiries fit our criteria? |
| Consultation booking rate | How many qualified enquiries book a consultation? |
| New-client conversion rate | How many enquiries become clients? |
| Client acquisition cost | What does each new client cost overall? |
Each metric answers a different business question. Add matter value where it is appropriately available.
Why Cheap Legal Leads Can Be Expensive
Duplicates, wrong practice areas, invalid numbers and unreachable prospects all inflate your raw numbers. Here is an illustrative example. Channel A costs £30 per enquiry, but only 10% qualify, so it costs £300 per qualified enquiry. Channel B costs £60 per enquiry, but 50% qualify, so it costs £120. The "cheaper" channel is actually the more expensive one.
How to Build a Legal Enquiry Reporting Dashboard
- Track enquiries from each relevant channel.
- Apply the same enquiry definitions everywhere.
- Record qualification outcomes, with access limited to the right people.
- Reconcile marketing data with your enquiry records.
- Compare cost and qualification rates by channel.
- Review regularly and adjust based on evidence.
Protect client confidentiality throughout. Follow UK GDPR, limit access and avoid storing more personal data than you need.

The SRA's marketing warning notice says firms must avoid prohibited unsolicited approaches and make sure third-party lead generators follow the rules.
