What questions should you ask an appointment setting agency?

What to take away

Ask for the ICO registration number, the lawful basis for calls and how opt-outs are logged before you discuss price.
Get the definition of a qualified appointment in writing, including who confirms it and within what time.
Check Companies House filings for accounts, filing history and any recent change of name.
Confirm who owns the prospect data and what happens to it when the contract ends.
Fix a pilot length and a notice period in the contract itself, not in an email.

Ask about ICO registration and call consent first

Any agency that calls UK businesses on your behalf handles personal data, so it must pay a data protection fee to the Information Commissioner's Office unless an exemption applies. Ask for the registration number and check it yourself.

ICO and call consent checks

ICO registration number, checked yourself
Lawful basis for each dialled list
TPS and Corporate TPS screening
Do-not-call reaches every dialler daily

Marketing calls to businesses sit inside the regime set out in the Data Protection Act 2018, so ask which lawful basis the agency relies on for each list it dials. Consent and legitimate interests are not interchangeable.

Ask how the agency screens numbers against the Telephone Preference Service and the Corporate TPS, and how quickly a do-not-call request reaches every dialler and list. A daily refresh is workable; a monthly one is not.

Check where the data came from

Ask for the source of every list: bought, scraped, inbound enquiries or built by the agents themselves. A claim that lists are built in-house only counts if the agency can describe the process and show a sample record.

Where each list came from

Bought
Scraped
Inbound enquiries
Built in-house by agents
Refresh, dedupe, gone-away removal
Suppression lists travel with you

Ask how records are refreshed, how duplicates and gone-away contacts are removed, and whether suppression lists travel with you if you move on. An agency that treats suppression data as its own asset is telling you something.

Put the contract and the data under review

Read the notice period, the auto-renewal clause and the exit conditions before you read the pricing schedule. Ninety days of notice on a monthly retainer is a warning sign, not a detail.

Contract and data review

Notice period and auto-renewal clause
Exit conditions before pricing schedule
Companies House filing history
Ownership of scripts and recordings
Ownership of CRM records and booked meetings

Check the company at Companies House for filing history, accounts and any recent change of name or registered address. A short trading history is not fatal, but it should change how much you pay up front.

Confirm in writing who owns the scripts, the call recordings, the CRM records and any appointments booked but not yet held when the contract ends.

Agree what a qualified appointment means

Most disputes come down to one word: qualified. Get the agency to define it in the contract, covering job title, company size, sector and location, and name the person who confirms the meeting happened.

Ask what happens to no-shows, cancellations and meetings the prospect pushes beyond the billing period. Decide whether those are credited, re-run free or billed as normal.

Scripts and follow-up emails are marketing communications under the CAP Code, so ask who writes them, who approves them and how versions are tracked. Our guide to UK appointment setting scripts shows what a compliant structure looks like.

Red flags that shorten the shortlist

Some answers disqualify an agency on their own. Use the table below to compare two or three providers side by side.

Red flag	Question that exposes it	What a good answer looks like
No ICO registration number	Can you give me your ICO registration number?	A number you can check on the ICO register
Vague definition of an appointment	What exactly makes an appointment qualified?	Named criteria and a named person who confirms the meeting
Silence on data ownership	Who owns the records when the contract ends?	You do, in a portable format, including suppression lists
Rolling 12-month term from day one	Can we start with a 30-day paid pilot?	Yes, with written exit criteria and fixed fees
Guaranteed meeting volumes	How do you guarantee volume?	No absolute guarantee, instead a range backed by comparable campaigns

Run a paid pilot before you scale

A pilot turns promises into evidence. Keep it short, paid and narrow.

Agree a 30-day pilot with a fixed fee and a written definition of a qualified appointment.
Give the agency one list segment and one script so results compare with your internal effort.
Review call recordings and CRM notes weekly, not at the end of the month.
Hold the second payment until the pilot's exit criteria are met.
Compare cost per held meeting against your own cost per meeting before you scale.

Pricing structures change which questions matter most. A retainer rewards activity, while a per-appointment fee rewards volume, so ask how each model handles a meeting that never happens. Our explanation of how pay per appointment pricing works covers the trade-offs.

Common questions

Do I need a UK-based agency?

Not strictly, but a UK-registered agency is easier to check at Companies House and simpler to pursue under UK contract law. If the calling team is overseas, ask how scripts handle UK consent rules.

How much do UK appointment setting agencies charge?

You will see retainers, per-appointment fees and hybrid models. Ask for the fee per held meeting on a recent comparable campaign, not a headline rate.

How long should a pilot run?

Thirty days or around 100 dialling hours is enough to judge call quality and answer rates. Anything shorter tells you about the list, not the agency.

Is a guaranteed number of meetings a red flag?

Not by itself, but a guarantee without a definition of qualification is worthless. Ask which meetings count and who decides.
