How to Choose a Lead Generation Agency in the UK: Prices, Checks and Red Flags

Pick the wrong lead generation agency and you tend to find out slowly: months of fees, reports full of activity, and a calendar that looks much as it did. Every message along the way went out in your name.

We run lead generation for UK B2B teams ourselves, so you should know my bias up front: we charge a fixed fee from £3,000 a month plus VAT. The first term is four months, then you’re free to stop every three months on 30 days’ notice, with no exit fee. Hold us to the same checks as anyone else.

The prices below are what UK providers publish about their own market. Each source is named and linked at the end.

What should you decide before you speak to agencies?

Decide what a result looks like for you. Lead generation can mean a list of contacts, a reply from someone interested, or a meeting booked with the right person. Each costs a different amount and suits a different agency, so settle it before the first call and every quote becomes easier to compare.

Then settle four more things:

• Who you want to reach: the sectors, company sizes and job titles, and any current customers to leave out.
• Who takes the meetings. An agency can fill your calendar, but someone on your side has to run the calls and follow up.
• What you can spend over the whole minimum term, not just the first month.
• How much of your time you can give: a kick-off, sign-off on messages, and feedback on each meeting.

If you’re buying meetings, write down what counts as a qualified one before you talk to anyone. Our guide to B2B appointment setting has a four-part definition you can borrow.

How do UK lead generation agencies charge?

UK lead generation agencies charge in four main ways: a monthly retainer for the whole campaign, a monthly fee for each SDR on your account, a fee per booked meeting, or a fee per lead. Some mix a smaller retainer with a bonus. The model decides who carries the risk while the campaign beds in.

Few agencies publish a starting price. Sopro is one that does: it says its pricing starts at around £3,000 a month, with no minimum contract. Air Marketing’s June 2026 guide shows how wide the market is, from £2,000 to £4,000 a month for a freelance SDR to £15,000 or more for an enterprise programme.

Paying per meeting or per lead suits a short test of a new market, as long as the definition is tight. A retainer suits outbound that runs for months, where you want the agency learning your market and sharpening the messages as it goes. For setup fees, tools and how to compare two quotes fairly, see our guide to outsourced SDR pricing in the UK.

What should you check before you sign with a lead generation agency?

Check five things before you sign: who does the work, whether you’ll see every message before it goes out, the minimum term and the notice that ends it, who keeps the data and sending domains at the end, and how the agency follows the UK rules on calls. Get each answer in writing.

1. Who does the work

The people on the sales call aren’t always the people on your account. Ask who will write your messages and who will send them, by name, who you’ll speak to each week, and whether they work only on your account.

Ask where they’re based, too, because location moves the price. Cape Solutions UK, which runs dedicated SDRs from South Africa for UK clients, lists a seat at £1,200 to £1,600 a month plus a £1,500 setup fee. Compare like with like.

2. Whether you see every message

Everything the agency sends goes out in your name, so you should see it. Ask to approve the messages before launch, and to see the lists, replies and numbers as the campaign runs, not only in a monthly summary. If you can’t see what goes out, you can’t judge what you’re paying for.

3. The minimum term and notice

A retainer may come with a minimum term, and the notice that ends it is easy to miss. Add up the full cost over the minimum term, not the first month. Then ask what happens if the results are poor: is there a review point, or a break you can use?

4. Who keeps the data and the domains

Ask what’s yours at the end. The contacts, conversations, replies and meeting notes should sit in your CRM as the campaign runs, not arrive in a report when it stops.

Sending domains are a separate question. Cold email should go from domains kept apart from your main one, so your own email’s reputation is protected. Many agencies, us included, set up and keep their own, so ask what happens to them, and to the tools and licences, when you leave.

5. The rules on calls

If calling is part of the plan, ask who screens numbers against the TPS and CTPS. The ICO says you must check numbers against these registers before live marketing calls. When an agency calls for you, you can both be responsible for following the rules, so the ICO also advises checking the agency’s reliability and having a written contract with it.

What are the red flags in a lead generation agency?

The biggest red flags are promises nobody can keep and work you can’t see. Be wary of guaranteed lead or meeting numbers before any testing, a price per lead with no written definition of a lead, messages you never approve, and a long minimum term with no way out.

• Guaranteed numbers from week one. Nobody can promise a figure before they’ve tested your market: new sending domains need warming and messages need testing first.
• A price per lead or per meeting with no written definition of what counts.
• No sight of the work: no access to the lists, messages or replies, only a monthly report.
• Messages in their voice rather than yours, sent without your sign-off.
• Calls with no TPS and CTPS screening, or with the number withheld. The ICO says you must not withhold your number on direct marketing calls.
• A long minimum term with no break or review point, and no clear answer on what you keep at the end.

What should you ask a lead generation agency on the first call?

Ask questions that show how the work gets done, not how good the results were. Find out who will run your campaign, what you’ll see and approve, how they define a qualified lead or meeting, the full cost over the minimum term, and what stays with you at the end.

• Who will run our campaign day to day, and do they work only on our account?
• Which channels would you use for us, and why those?
• Will we approve every message before it goes out, and see the lists and replies as they come in?
• How do you define a qualified lead or meeting, and what happens after a no-show?
• What’s the total cost over the minimum term, including setup, data and tools?
• How much notice ends the contract, and is there an exit fee?
• If we pay per lead, is each lead ours alone?
• Who screens call lists against the TPS and CTPS?
• When we leave, what’s ours and what stays with you?

Write the answers down, and ask every agency the same questions. Straight answers on what you’ll see and what you’ll keep matter more than any case study.

Should you use a lead generation agency or hire in-house?

Use an agency to start quickly, test a market or avoid managing a hire. Hire in-house once the message is proven, outbound is a permanent part of how you sell, and someone has time to manage and coach the rep. By our estimate, an in-house SDR costs about £55,000 to £60,000 in year one.

The Lead Generation Company puts an in-house salary at £30,000 to £45,000, and the true cost closer to £40,000 to £60,000. A hire also takes time: recruiting, their notice period, then months to ramp. An agency skips the recruiting and the notice period, so the first outreach can go out sooner.

We set out the year-one numbers line by line in in-house SDR vs outsourced outbound, and cover the options in between in alternatives to hiring an SDR.
