What is the difference between an exclusive and a shared double glazing lead?

A shared lead is sold to more than one installer at the same time; an exclusive lead goes to one company and is never resold. With a shared lead the homeowner takes calls from every buyer of that enquiry, and the sale usually goes to whoever rings first and quotes best. With an exclusive lead you are the only company calling.

Are shared window leads cheaper?

Per lead, yes. Shared leads are a volume product with the competition priced in, so the headline cost is lower. What you are buying is a fraction of an opportunity, and the fraction shrinks every minute you are not the first caller.

How do I check a lead is genuinely exclusive?

The word gets used loosely in this industry, so ask any provider to put exclusivity in writing and to say what happens if a lead turns out to have been resold. Then ask the homeowner on your first call how many other companies have rung. Your own contact rate will tell you the truth inside a week.

Are Lead Pronto's double glazing leads exclusive?

Yes. Every window, door and double glazing lead we sell goes to a single installer and is never resold. They are generated in house through our own paid social and PPC campaigns rather than bought in as data, and windows and doors is our largest and oldest sector - we have run window campaigns since 2018.

What happens if a lead is not usable?

A rejection policy is included, so wrong numbers, renters and duplicates go back to your account manager rather than onto your invoice. Agree what the policy covers before the campaign goes live.

Exclusive vs Shared Double Glazing Leads

Q: How many exclusive window leads turn into appointments?

It depends on your own follow-up, but the model scales. On our national campaign for Anglian Home Improvements, 3,015 leads produced 1,282 booked appointments, an appointment rate of 42%.

A shared double glazing lead is sold to more than one installer at the same time; an exclusive lead goes to one company and is never resold. Lead Pronto only sells exclusive window, door and double glazing leads - from £15 per lead, generated in-house - so we are open about which side of this argument we sit on. The mechanics below hold whoever you buy from.

What a shared lead actually is

When a homeowner asks for double glazing quotes on a comparison-style site, that enquiry is often sold to several installers at once. Each pays a lower price, and each is racing the others to the phone. The homeowner, who expected a quote or two, takes calls from every buyer of the lead - and by the third one, patience is thin and the price war has started.

Shared leads are not a con; they are a volume product with the competition priced in. But the headline cost per lead hides the real terms: you are buying a fraction of an opportunity, and the fraction shrinks every minute you are not the first caller.

What exclusive means, and how to check it

An exclusive lead is delivered to your company alone and never resold - one installer, one conversation, no race. The word gets used loosely in this industry, so make any provider put it in writing, and ask the homeowner on your first call how many other companies have rung. Your own contact rate will tell you the truth within a week.

The real cost difference

Exclusive leads cost more per lead and usually less per sale. A shared lead only pays off if your team reliably wins the race to the phone and the quote battle that follows; an exclusive lead converts on the strength of your survey and your price, which you control. Work it out backwards from installs, not downwards from lead price: leads per conversation, conversations per survey, surveys per sale. That arithmetic - not the headline price - is where shared leads tend to lose.

Why Pronto sells window leads exclusively

Windows and doors is our largest and oldest sector - we have run window campaigns since 2018 - and everything we have learnt says the exclusive model is what keeps installers with us. Every one of our double glazing leads is generated in-house through our own paid social and PPC (Google Ads) campaigns, delivered to a single installer, and covered by a rejection policy. We never resell a lead, and our commercial model depends on your cost per sale working: we win when you win.

The model scales. On our national campaign for Anglian Home Improvements, 3,015 leads produced 1,282 booked appointments - a 42% appointment rate.

What exclusive double glazing leads cost

Our exclusive window and door leads start from £15 per lead, on a Pay-Per-Lead model with no long-term contract, and new partners can receive 20 free leads after their first 100 paid leads. If your bottleneck is call capacity rather than lead flow, window and door appointments start from £130, with the homeowner already booked into your diary.

Questions to ask before you buy

Is exclusivity guaranteed in writing - and what happens if a lead turns out to have been resold?
How is the lead generated: the provider's own advertising, or bought-in data?
Is there a rejection policy for wrong numbers, renters and duplicates?
How quickly does the lead reach you after the homeowner enquires?
Can volume be held to what your fitting teams can actually survey?

We answer all five before any campaign starts. See our double glazing leads page for current pricing and coverage, or talk to a specialist about your area.
