Should you charge a service call fee?

The fee is usually set the way prices get set in a trade: by looking at what the firm down the road advertises. That produces a number in the right region and answers none of the question, because the fee is not really a price. It is a qualification device applied before any conversation, and what it qualifies for depends entirely on who is encountering it.

Both of its effects are real and they run at the same time. A fee deters people who were collecting free estimates with no intention of buying from you, which is a genuine saving in technician time and van movement. It also deters people who would have bought, but who saw a charge where a competitor showed none and simply moved on. Neither effect is visible in your accounts: the first shows up as work you did not do, and the second as an enquiry that never arrived.

The variable that decides which effect dominates is the channel, and this is the part that turns the decision from a guess into something answerable. An enquiry from a customer who searched for your trade with an urgent problem arrives with intent already established, and a call-out fee reads to them as normal and professional. An enquiry from a comparison surface, where the customer is looking at several firms side by side and free estimates are advertised beside your charge, arrives with no intent at all, and the same fee reads as a reason to click the next result. The identical policy has opposite effects on the two populations.

That gives a workable rule that is more precise than a single figure: set the fee where the intent is, and waive it where the comparison is. In practice that means charging on inbound calls for urgent work, and either waiving or crediting the fee on enquiries arriving through comparison channels — with the credit applied against the job, which preserves the filter against pure tyre-kickers while removing the barrier for buyers.

The credit-against-the-job structure is worth more than it looks, because it changes what the fee communicates. A fee that is refunded on booking says the charge exists to protect the technician's time, which most customers accept. A fee that is retained regardless says the visit is the product, which is only true for genuine diagnostic work and is heard as a penalty everywhere else. Firms that make this distinction explicit in the first conversation usually stop needing to argue about the fee at all.

The measurement to run before changing anything: record what share of enquiries end at the moment the fee is mentioned, split by channel. It is one field on a call form and it turns the whole decision into observation. Almost nobody records it, which is why the fee gets debated on the basis of what competitors advertise for another year.
