What commission-only actually means
Commission-only means you are paid a percentage of each closed deal, and nothing when you do not close. Typical UK contracts pay 10-20% commission on offers priced between £2,000 and £10,000. The percentage sits at the lower end when the company supplies high volumes of warm, pre-qualified leads and at the higher end when the closer carries more of the pipeline themselves.
So the arithmetic is simple and the outcome is not. The rate is knowable in advance; the number of deals is not. Deal count depends on the quality of the offer, how many booked calls actually show up, how well the leads were qualified before they reached you, and your own conversion rate, which for a new closer is unknown until they have taken several dozen live calls.
Payment terms matter as much as the percentage. Ask when commission is paid (usually on cleared funds, not on signature), what happens on instalment plans, and what the clawback policy is if a client refunds inside a guarantee window. Get all three in writing before you take a single call.
