Always put your Gas Safe registration number on the quote itself, beyond your invoice or van signage. Customers increasingly check the register before booking any gas work. Having the number visible on the document they're deciding over is a stronger trust signal than any amount of marketing copy about being "fully qualified."

Manufacturer warranties on boilers are almost always conditional on annual servicing, and that condition is easy for a customer to miss until they need to make a claim. State it plainly: "10-year warranty subject to annual service." It's more than covering yourself. It's the kind of detail that makes a customer trust you enough to book that annual service with you instead of shopping around each year.

A power flush or system clean is easy to skip on a quote and hard to justify afterwards if you do. List it as its own line, with a short explanation that it protects the new boiler from debris circulating from the old system. That turns what could look like an upsell into an obviously sensible part of protecting the customer's new investment.

For system installs, and not swaps alone, state which radiators and pipework are included versus assumed adequate. A customer expecting a full upgrade to every radiator, when the quote only covers the boiler and immediate connections, is the most common source of "that's not what I thought I was paying for" on heating jobs. A one-line scope note prevents it entirely.
