Its solar panel leads page lists what every solar appointment is held to before it reaches your diary:
It says its own UK agents make the qualifying call, a QA team reviews booked calls from the recordings, and the roof question is a check on the phone, not a survey.
Watts says it funds the advertising itself and owns the consumer brands homeowners enquire through, with enquiries from Facebook, Google, organic search and referrals. It says it does not cold call: every homeowner has filled in a form or asked to be called back. It says it does not install or sell systems, so its consumer brand is not competing with you.
On its about page it describes itself as the UK's largest exclusive lead-generation company and says it has booked more than 561,000 appointments across its sectors since 2015; its solar page puts solar at more than 255,000. Those are its own figures; we have no way to check them.
The solar page says anything that does not go ahead is returned and replaced, and an appointment that does not meet the brief can be returned for credit; a roof that cannot carry a workable design counts. It is pay as you go with no contract, no minimum and free setup, and most installers start with a week of appointments. It does not publish a price per appointment.
Because Watts screens on income, credit and age, its appointments are shaped for domestic solar sold with finance. If you sell to businesses, none of those checks apply and the customers are not the ones you need.
You might look elsewhere if:
Get the answers in writing. They are the same questions we would expect any installer to ask us, and they decide what a lead really costs you.
Then compare suppliers on cost per signed job, not price per lead. Our solar cost per lead calculator works it through with your own figures.
The right alternative depends on what you install and what you want to pay for: an enquiry, a booked appointment or a meeting that actually takes place. Our comparison of 15 UK solar lead suppliers sets them side by side on price, exclusivity, contract and no-show terms, and Lead Pronto alternatives covers ten more in detail.
TNW Marketing books exclusive, pre-qualified commercial solar site appointments for UK installers. Each appointment goes to one installer. The published band is £250 to £1,000+VAT per attended appointment, set by system size and qualification, with no retainer and no monthly fee. You only pay for appointments that are actually attended, and any that aren't viable we replace.
TNW and Watts both book exclusive appointments into installers' diaries with no contract. The difference is the customer: Watts books homeowners, TNW books business owners for commercial systems, checked for ownership or landlord consent, energy spend, roof suitability and who signs off the spend. If you install domestic solar, Watts or another homeowner supplier will suit you better than we will.
For domestic installers it offers exclusive, credit-screened homeowner appointments with no contract and no minimum, by its own website (read 9 Nov 2026). It books homeowners only, so commercial installers need a different supplier.
It does not publish prices. Its solar page says you pay per appointment as you take them, with no contract, no minimum and free setup.
Yes, by its own description: each solar appointment goes to one installer and is never passed to a second company.
Its solar page says anything that does not go ahead is returned and replaced, and an appointment that does not meet the brief can be returned for credit.
Yes. Watts Marketing Limited is an active company, number 07250927, incorporated on 12 May 2010, with its registered office in Norwich (Companies House, checked 9 Nov 2026). Its site says it has been booking appointments since 2015.
Its solar page says it does not: every homeowner has filled in a form, asked to be called back or started looking into solar before its agents call them.
