Win the lead first. Not third.
AI agent rings every Effy, Heatable or GreenMatch lead inside 60 seconds, captures the four MCS pre-survey fields, books the site visit. Customer doesn't get a chance to click the next installer.
Average solar lead response time. 78% of buyers book with whoever calls first. Five installers race for the same comparison-site form.

What changes when AI gets the call instead.
Lead-to-appointment conversion
Setter AI's 2025 solar-cohort data: AI voice qualifying inside 60 seconds versus 47-hour industry average. Surveys booked before the customer closes the comparison-site tab.
After-hours lead leak
Comparison-site leads land at 9pm. Your AI agent calls back. Effy's next installer doesn't, and you've already booked the survey by morning.
Survey handover, every time
Roof aspect, pitch estimate, current annual kWh consumption, shading flags, captured before your MCS surveyor leaves the office. No more 90-minute drives to north-facing roofs.

Plugs into your installer stack.
What your week looks like.
- £20–£80 shared comparison-site lead. Five installers receive it the same minute
- Your BDR calls 47 hours later, customer already booked the survey with someone else
- Out-of-hours leads (90% land 6pm–10pm) sit untouched until Monday morning
- Surveyor drives 90 minutes to a north-facing roof at 8° pitch, system never sized properly
- Webhook fires from Effy / Heatable / OpenSolar, AI agent dials in under 60 seconds
- Captures roof aspect, pitch estimate, annual kWh, shading, current supplier, your surveyor's pre-call checklist
- Books the MCS-certified surveyor's calendar in one go (English + your second language)
- Listed / off-grid / flat-roof properties flag automatically for a human callback
“A £20 shared lead at 5% conversion is a £400 CAC. The maths only works if you call within five minutes.”

Questions buyers in solar actually ask.
Anything missing? hello@callsy.ai.
Can it really call a new lead in under 60 seconds?
Yes, a webhook from HubSpot, OpenSolar or your comparison-site feed triggers an outbound call before the customer closes the Effy tab. UK number, identified as your firm. Audit log proves the speed-to-lead for every record.
Will it talk kWp and roof orientation correctly?
It captures roof aspect, pitch estimate, annual kWh consumption and shading flags. The four fields your surveyor needs to pre-qualify before a site visit. It does not quote a system size; that's the surveyor's job. No misleading energy-output promises.
Does it know MCS rules?
It doesn't give MCS technical advice. It captures the data, books the MCS-certified surveyor's slot, and flags any property (listed, off-grid, flat roof, conservation area) that needs a human callback. MCS scope guardrails are wired into the script.
Can it handle finance questions?
It explains your finance options at the level published on your site (e.g. 0% over 24 months via Phoenix / Sungage), books the call with your finance specialist, and never quotes APR off-script. Consumer credit boundaries (FCA) respected.
What about the SEG / export tariff?
It explains your default SEG partner and rate, captures the customer's current electricity supplier, and flags it for the surveyor. FIT-era language scrubbed. No 'feed-in tariff' references that would date your firm.
