For solar installers with established ad spend and lead volume
Homeowners requesting a quote ask 3–5 installers at once. Whoever calls back first wins the decision, almost regardless of price — the research behind that is what's in the video above.

The Documented Cost of a Slow Callback
A lead contacted within five minutes is 21 times more likely to book than one contacted after thirty. MIT and InsideSales.com, Lead Response Management study.
Even the UK's largest residential installer sells responsiveness as a trust signal, not just price or warranty. The competitive bar is speed, and most installers don't know they're losing on it.
Exclusive leads run £50–£150. Shared leads convert at just 5–10%. Losing a fifth of those to response delay is not a rounding error on a budget that size.
Sentinel contacts every lead within two minutes, in your name. No software, no new hire, no change to how you work.
What Installers Ask Before They Start
Straight answers.
The 8–12 hour figure comes from measuring actual response times, not stated policy. Most owners believe their team responds within the hour. The data says otherwise, almost every time we check.
A notification tells you a lead arrived. It doesn't contact the lead or keep following up until it books or says no. That's the part Sentinel operates.
Worth checking before assuming it's true. A lead that goes cold because nobody called for hours looks identical to a bad lead. You won't know which is which until something actually replies.
No software to install, nothing to unwind. And if we don't hit the agreed minimum of qualified conversions within 60–90 days, we keep working at no extra cost until we do.
Depends on your lead volume and average install value, worked out on the call. Pricing is performance-aligned.
