Outsourced lead generation: what it costs and what to watch for

Why trust this page: I spent years on the other side of this, booking appointments for clients at a lead-generation agency and running a team of more than 20 callers. I don't sell appointment setting now. I build the marketing that brings enquiries in, so I've an interest in you not needing a calling agency forever, and I'll say when you do. Prices below come from UK providers' own pages, checked in October 2026, and I've labelled them.

What is outsourced lead generation?

Outsourced lead generation is when you pay an outside firm to find the right businesses, start conversations with them and hand you booked sales meetings. Most UK providers do it by phone, some by cold email or LinkedIn, and the better ones mix all three. You still take the meeting and close the sale. They fill the top of your pipeline.

It covers a few different services that get lumped together: appointment setting (they book meetings in your diary), lead lists (they hand you names and numbers), and full outbound programmes (a dedicated caller or team working your market every day).

What does outsourced lead generation cost in the UK?

Expect to pay a monthly retainer of about £2,400 for a part-time entry programme, rising to £5,000 to £11,000 a month for a senior-led campaign. Some firms charge per meeting instead. Compare them on the cost of each qualified meeting that actually happens, because a cheap retainer that books the wrong people is the most expensive option.

Every one of those figures comes from a firm that sells the service, so treat them as a guide, not a survey. Nobody publishes independent UK numbers on this. The useful sum is yours: what is one new client worth to you over a year, and how many meetings do you need to win one? If a client is worth £20,000 and you win one in five meetings, a £300 meeting is cheap. If a client is worth £2,000, it isn't.

Which pricing model is best?

No model is best on its own. A retainer buys effort, pay per meeting buys outcomes, and a hybrid splits the risk. For most small B2B firms a hybrid or a short retainer trial is the safest start, as long as you agree in writing what counts as a qualified meeting.

• Monthly retainer. You pay for a caller's time, usually per seat. It's predictable and suits a long sales cycle. The risk is paying for activity rather than results, so ask for the dials, conversations and meetings every week.
• Pay per meeting. You only pay when a meeting is booked or held. The risk sits with the provider, which pushes them towards volume. Agree what "qualified" means, and whether you pay for no-shows.
• Hybrid. A lower retainer plus a fee for each meeting. In my view it's the fairest for both sides, so ask for it even if it isn't on the price list.

What I learned from the inside

The biggest lesson from years on the phones is that the meeting count on the report is rarely the number that matters. What matters is how many of those meetings were with the right person at the right kind of firm, and how many turned into sales.

When I was calling, I finished in the top 3 of 18 agents at 3.2 sales an hour against a target of 2.0. Later I ran a team of more than 20. A few things held true the whole time:

• Most meetings come from callbacks, not first calls. A provider that doesn't chase properly is throwing your money away. I've written about why callbacks matter more than first calls.
• Speed decides a lot. When a prospect says "call me Thursday", the ones who call Thursday morning book the meeting. The same goes for your own enquiries, which is why speed to lead is the cheapest fix I know.
• Volume matters less than a good opener and fast follow-up. That's the main thing I took from those numbers. Ask a provider how they open a call, not just how many calls they make.
• The numbers can be real. By my own records I booked more than 200 solar appointments, and nine in a single day. So a provider that can't show you its own numbers has no excuse.

Is outsourced cold calling legal in the UK?

Yes, as long as it follows PECR. You can make live marketing calls to business numbers that aren't registered on the TPS or the CTPS and haven't told you to stop. Companies register on the CTPS, and sole traders and some partnerships on the TPS, so a B2B list has to be checked against both, plus your own do-not-call list.

That's from the ICO's guidance on telephone marketing. The part most buyers miss: the ICO's rules on live marketing calls say responsibility sits with the caller or the "instigator" of the call, and that using an agency "can mean you both have responsibility". The ICO also expects you to check the agency is reliable on compliance and to have a written contract. A new registration takes 28 days to become active, so lists screened long ago go out of date. Ask how recently they screen. (This is general guidance, not legal advice, and the ICO notes its guidance is under review after the Data (Use and Access) Act.)

Red flags to watch for

The warning signs are the same ones I saw from the inside: promises nobody can keep, numbers you can't check, and contracts that lock you in before you've seen a single meeting. Walk away if you see more than one of these.

1. A guaranteed number of meetings or sales, with no definition of "qualified".
2. No sight of call recordings or the actual emails being sent in your name.
3. A 12-month contract with no review point or break clause.
4. Vague answers on TPS and CTPS screening, or no written contract on data.
5. Reports that only show activity (dials, emails sent), never meetings held or deals.
6. Callers who don't know your service well enough to answer a basic question about it.
7. Meetings booked with people who can't make the buying decision.

Questions to ask before you sign

Ask these on the first call. A good provider will answer them without hesitating, and how they answer tells you more than their case studies.

• Who will actually make the calls, and can I speak to them before we start?
• Where does the data come from, and when was it last screened against TPS and CTPS?
• What counts as a qualified meeting, and what happens if someone doesn't turn up?
• Can I hear recordings every week?
• What's the minimum term, and what's the break clause?
• What do you need from me each week to make this work?

Outsource it or build it yourself?

Outsource when you need meetings fast and nobody in the business can make calls. Build it yourself when the owner is already the best salesperson and the gap is time, follow-up and a website that backs up every call.

When I was calling, I asked owners "Do you do any marketing?" hundreds of times. In my experience about nine in ten said some version of "not really, no time", and they were usually the good firms, busy with work. That's the gap to fix: time, not interest.

Outsourced callers can fill a diary, but the leads stop the day the contract does. A website that answers buyers' questions, a lead generation funnel that captures enquiries and a CRM that chases them keep working. If you'd rather keep calling yourself, sales training and simple call systems are often cheaper than a year of retainers. You can see what each option costs on my pricing page.

The practical summary

• UK outsourced lead generation runs from about £2,400 a month to £11,000 or more.
• Judge it on the cost per qualified meeting held, against what a client is worth to you.
• Hybrid pricing with a written definition of "qualified" is usually the fairest start.
• You share legal responsibility for calls made on your behalf, so check the screening.
• Callbacks and speed win meetings. Ask how the provider handles both.
• If the owner sells well, build the inbound side so you rely on outside callers less.
