Jerome RappelIf you fit boilers or install central heating, buying leads is one of the fastest ways to fill your diary - but only if you understand what you're actually paying for. Here's a clear look at what boiler leads cost in the UK in 2026, what moves the price, and how to tell a good deal from a bad one.
How boiler lead pricing is quoted
This guide does not provide a verified market-wide price benchmark. Request a written quote for exclusive, real-time boiler leads, specifying repairs, servicing, new installations or system upgrades, your postcodes and the qualification required.
For a shared-lead quote, ask how many firms receive the enquiry and when it was submitted. Compare the actual price and your observed cost per booked job; a lower lead price alone does not establish better value.
What drives the price
- Job type: specify whether you want servicing, repairs or installation enquiries.
- Location: request quotes for the exact postcodes your team covers.
- Season: review your own seasonal demand and compare quotes at the time you plan to buy.
- Exclusivity: confirm that the supplier will deliver the enquiry to one buyer only.
The number that actually matters
Stop comparing leads on price per lead. The figure that decides your profit is cost per booked job - your total lead spend divided by the jobs you actually win.
In a hypothetical example, a £15 lead closing at 5% costs £300 per booked job, while a £45 lead closing at 20% costs £225. These assumptions illustrate the formula; they are not campaign results or typical conversion rates. Our free ROI calculator works this out for your own numbers in seconds.
How to get more from every lead
Reply promptly, agree a convenient appointment and provide a clear written quote. Keep a record of contact attempts, quotes and bookings so you can assess your own results. Exclusive delivery does not guarantee that a homeowner has not contacted another installer independently.
