Questions

Installer FAQ

You need to be MCS certified, or operating under a recognised MCS umbrella scheme. This is the government-recognised standard for retrofit installations and is required to submit BUS or Warm Homes grant applications on a homeowner's behalf. We verify your certificate or umbrella scheme membership before approval.
Each lead includes: full name, verified mobile number, email address, full property address, postcode, EPC band, heating type, property type, tenure, income band, qualifying benefits status, measures of interest, and grant eligibility summary. You have everything you need to make the first call.
Each lead is charged individually at £80 via Stripe — pay per lead, nothing more. Once your payment is confirmed, we immediately send you the full verified lead pack: name, mobile number, email, full address, EPC band, heating type, income band, benefits status, measures of interest, and grant eligibility summary. There are no monthly subscription fees and no minimum volume commitments. We offer a small number of trial leads at no cost during your first month to establish the relationship.
Yes. You can pause lead delivery at any time — for example during busy periods or staff holidays. You can also adjust your borough coverage or measure preferences. Just let us know via email and changes take effect within 24 hours.
All leads are OTP-verified at time of submission, so bad numbers are extremely rare. If you receive a lead where the number is genuinely unreachable after three attempts across two days, raise it with us and we'll review on a case-by-case basis.
We strongly recommend calling within 24 hours of receiving a lead. Homeowner intent is highest immediately after submission. We notify you by both SMS and email when a lead is assigned. Leads not contacted within 48 hours may be re-routed.
