For MCS air source installers

Exclusive air source heat pump leads, without paying for leads upfront. £50 + VAT as each verified lead arrives.

Every homeowner completes an 11 question survey, verifies their mobile by text PIN, and is checked against your radius. Only then is your card charged and the lead sent to you. £1 to activate your area.

Takes about 60 seconds. You’ll see straight away if your area is open.

How it works

Five steps.
You only pay at step four.

01

11 question survey

The homeowner asks for an air source heat pump quote and completes our survey. Browsers, renters and unsuitable homes are filtered out.

02

Mobile verified by PIN

They confirm their mobile with a text PIN, so the number is real and belongs to the person who filled in the survey.

03

Radius confirmed

We check their postcode sits inside the area you cover. You never pay for a job you would not travel to.

04

Card charged

£50 + VAT. Charged only once a verified lead in your area exists. No lead, no charge.

05

Lead delivered

Straight away, into the Nebelli app on your phone, with a tap-to-call text and an email with every survey answer.

£50 + VAT

per lead, charged only once it is verified and inside your radius.

1

installer per area. Your leads are never shared or resold.

Replaced

if a lead is bad: a dead number, the wrong person, or a repeat.

What to expect
30 to 40%

of recent leads have turned into a survey appointment.

Results vary by area and by how fast the homeowner is called. Most installers start with 20 to 30 leads to get a fair picture.

5mins

Speed books surveys

Installers who call within 5 minutes of the text arriving tend to book more surveys. Research on web enquiries found calling within 5 minutes, rather than 30, made contact 100 times more likely.1

Built by an engineer

Proven with a
real installer first.

I spent 16 years as an engineer before marketing. My brother runs an MCS-certified air source firm in Suffolk, and I built this funnel on his business before offering it to anyone else.

I build and run it myself, so you deal with the person who made it.

“If it’s not right for you, you stop. No contract, just £1 + VAT to start.”

Before you ask

How am I charged? +
A one-off £1 activation fee saves your card and switches your area on. After that, it’s £50 + VAT per lead, charged only once a homeowner in your area has completed the survey and verified their mobile. No monthly fee, and nothing else ever appears on your card.
Is there a minimum order? +
You set a monthly limit of at least 20 leads, because that is enough to see a real pattern rather than one lucky or unlucky week. It is a limit, not a commitment: you only pay for leads you receive, and you can change it, pause or stop whenever you like.
What if a lead is bad? +
We replace it if the number is dead or invalid, the details belong to someone who didn’t ask, or it repeats a lead sent to you in the last 90 days. Every mobile is PIN verified, so this should be rare. Report it within 3 working days. To be straight: we don’t replace leads that simply don’t convert or aren’t ready yet. The survey does the qualifying, the closing is yours.
Are the leads shared? +
Never. One installer per area. Each lead goes to you alone and is never sold on or recycled.
Do I need to be MCS-certified? +
Yes. We only match homeowners to MCS-certified air source installers. If you are mid-application or working through an umbrella scheme, tell us and we will talk it through.
Do I sign a contract? +
No. No contract, no exit clause. If it isn’t working for you, you stop.
One installer per area
