How many boiler installation enquiries do I need?
Divide your monthly install target by the share of enquiries you quote, then by the share of quotes you win. Put your own numbers in below and the calculator does the rest, straight away, in your browser.
The calculator
How the calculator works
Every boiler installation starts as an enquiry, and two things happen between that first call and a booked job. Some enquiries never become a quote: the homeowner went elsewhere, it turned out to be a repair, or you couldn’t get out in time. Then some quotes are won and some aren’t.
So the number of enquiries you need is your install target, divided by the share you quote, divided by the share of quotes you win. If you quote 6 in every 10 enquiries and win 4 in every 10 quotes, only about 1 in every 4 enquiries becomes an install, and 8 installs a month needs around 34 enquiries.
Why the two rates matter as much as the leads
Move the sliders and you’ll see that a small change in either rate changes the answer a lot. That is good news, because both rates are largely in your hands. Answering every call quickly, getting out to quote while the homeowner is still keen, and following up every quote that goes quiet all lift them without a single extra lead. I cover the follow up side in Found on Google, Lost on the Quote.
Where the enquiries come from
Once you know your number, the next question is where those enquiries will come from each month, steadily rather than in bursts. My complete guide to getting boiler installation enquiries from Google walks through every option, and my boiler installation leads page explains how I bring them in for firms through Local Services Ads and Google Business Profile.
My promise to the firms I work with is “15 to 25 consistent boiler installation enquiries every month within 90 days, or we keep working for free until we do.”
If your number looks a long way from where you are today, I’ll show you where your next enquiries could come from in a free 5 minute video plan, with no call and no meeting.
Questions people ask
How do I work out how many enquiries I need?
Divide your monthly install target by the share of enquiries that turn into a quote, then by the share of quotes you win. If you want 8 installs, quote 6 in every 10 enquiries and win 4 in every 10 quotes, that is 8 divided by 0.6 divided by 0.4, which comes to about 34 enquiries a month.
What if I don’t know my numbers?
Look back over the last two or three months. Count the boiler installation enquiries you had, how many you went out and quoted, and how many said yes. Rough figures are fine; the calculator is there to show which number matters most for your firm.
Which number should I improve first?
Try changing each one by a single step in the calculator and see which brings the enquiries you need down the most. For many firms, answering every call quickly and following up every quote moves the result as much as finding more enquiries.
What counts as a boiler installation enquiry?
In my work, an enquiry is a call from an active homeowner looking to get a boiler installed. Breakdown calls and small jobs are useful work, but they don’t count towards an install target.
