Why choose Lead Gems as your lead generation agency
Most agencies sell you clicks. We are paid to deliver clients, so we build every step between the first search and the signed contract, and we measure all of it.
We test on our own money first
Lead Gems runs its own lead generation brands. Every strategy is proven on our budget before it reaches yours.
Tracking before spending
Calls, forms and bookings are tracked into your CRM from day one, so every decision is based on clients, not clicks.
Senior people, no hand-offs
The specialists who plan your campaigns are the ones who run them, and you can reach them directly.
Lead generation services
One agency for the whole journey.
Most businesses buy clicks from one agency, a website from another and hope the leads follow. As a full-service lead generation company, we run every step, so nothing leaks between them.
Paid traffic
Enquiries this month, at a cost per lead you can plan.
Convert
More enquiries from the visitors you already pay for.
Follow up
Every lead answered in minutes and tracked to revenue.
Your clients now ask ChatGPT who to call.
ChatGPT Ads place your business beside the answer. We set them up with the same tracking-first approach we use on Google, and we help you get named inside the answer itself.

18
new clients, £210,000 average assets
A North West independent financial adviser was buying shared leads that rarely converted. We replaced them with exclusive, qualified pension leads through a two-stage Google and Meta funnel, automated lead grading and instant follow-up.
98
treatments, £1,850 average value
A Surrey private dental practice wanted to grow its cosmetic and implant work but had no paid advertising and no way to book online. We launched Meta and Google campaigns, added an AI chatbot and automated appointment reminders.
31
new paying customers
A London B2B software company was spending heavily on outbound sales with slow results. We built a LinkedIn and Google Ads funnel aimed at operations directors in mid-size professional services firms, with a six-email nurture sequence.
What our clients say
In their own words.
Quotes from the clients behind our case studies. Each one links to the full story and the numbers.
"We had written off Google Ads after our first attempt. Lead Gems showed us the difference proper campaign management makes. We now have a predictable flow of the right type of enquiries every month."
"I was paying Checkatrade and getting the same leads as four other plumbers. Now I get my own leads, at a lower cost, and they are only coming to me. The review automation alone has transformed my Google ranking."
"I was spending hours every day replying to Instagram messages and still losing bookings because people could not book when it suited them. Now they book online any time of day, I have an email list I can market to directly, and the Meta ads bring in more new clients in a week than I used to get in a month organically."

Lead generation questions
Straight answers.
What does a lead generation agency do?
A lead generation agency brings you enquiries from potential clients through channels such as Google Ads, social media advertising, SEO and email, then helps turn those enquiries into clients. Lead Gems also runs the follow-up and the tracking, so every lead is measured all the way to revenue.
How much does lead generation cost in the UK?
It depends on your sector and channel. Across our own campaigns, cost per lead typically runs at £15 to £45 for dental practices, £30 to £80 for accountants, £40 to £120 for solicitors and £60 to £150 for financial advisers. Most UK small and medium businesses invest £1,000 to £5,000 a month in advertising. Our free growth call shows you the figures for your market.
What is the difference between a lead generation agency and a marketing agency?
A marketing agency is usually measured on activity such as reach, traffic or rankings. A lead generation agency is measured on enquiries and the clients they turn into. Lead Gems runs the same channels a marketing agency would, but builds and reports everything around cost per qualified lead and cost per client.
How quickly will we see new leads?
Paid campaigns usually bring in enquiries within days of launch. Most accounts need four to eight weeks of data to bring cost per lead down to a stable level. SEO takes three to six months to build, which is why many clients run both.
Which businesses do you work with?
Service businesses that win clients through enquiries: solicitors, accountants, financial advisers, mortgage brokers, dental and aesthetics clinics, trades and B2B companies. We work with them across the UK from our offices in London and Birmingham. Unlike many lead generation companies in the UK, we never sell shared leads: every enquiry comes from your own campaigns and belongs to you alone.
How do you measure success?
By cost per qualified lead, cost per client and return on ad spend, never by clicks or impressions on their own. Every number sits in a live dashboard you can check at any time.
Will we own our ad accounts and data?
Yes, always. Your ad accounts, website, CRM and data are set up in your name, and you keep full access whether you stay with us or not.
