For businesses buying enquiriesHome battery leads in the Netherlands

For home battery installers who want enquiries from homeowners who would like a battery assessed.

Which enquiries you receive

The applicant wants to find out whether a home battery suits their property. Whether solar panels are present and the purpose of storage have been discussed by phone. The request may be for a quote or for an initial assessment.

Enquiries from homeowners considering a home battery assessment.

What we check by phone

We have spoken to the applicant about the project, timing and agreed criteria. Stated budgets and measurements remain estimates unless specified otherwise.

  • Owner or authorised decision-maker
  • Solar panel ownership recorded
  • Storage objective discussed
  • Budget indication or advice need recorded
  • Project planned within 6 months

What the enquirer states

These details are the enquirer's own indications and are marked as such in the brief.

  • Solar panels present: yes or no, and the number if known
  • Purpose of storage, for example using more of their own electricity
  • Estimated annual consumption, where known
  • Presence of a heat pump or EV charger
  • Budget indication, or a note that the budget is still to be defined

What you do not receive

  • Applicants who only want a return calculation, with no interest in a quote
  • Tenants without the owner's permission
  • Standalone questions about subsidies or net metering
  • Projects outside the agreed service area

Please note: Klantwerf does not state that a home battery falls under the ISDE. The end of net metering (saldering) on 1 January 2027 does not mean a battery will be profitable; no return or payback period is promised.

Service area

You choose postcodes or municipalities. We confirm per region whether enquiries are feasible; without that confirmation we promise no volume or delivery time.

Exclusive, and what that means

Klantwerf supplies the same enquiry to one buyer. The applicant may independently contact other providers.

No. You receive a qualified enquiry. Your business handles the quotation, sale and delivery of the work.

Something wrong with an enquiry?

Report incorrect details, a duplicate or a mismatch with the agreed criteria within 7 calendar days. Valid claims receive a replacement or credit after review. Terms are agreed before you start.

Valid reasons

  • Incorrect or non-existent contact
  • No genuine enquiry
  • Outside the agreed service area or criteria
  • Duplicate Klantwerf enquiry for the same project and the same buyer within 90 days

Not a valid reason

  • The enquirer later changes their mind
  • No contract or sale results from the enquiry

Is the enquirer unreachable after delivery? Report it with a short description of your attempts; we review each case individually. As a guideline: three reasonable attempts over two working days, and never continuing after an objection.

A valid report leads to a replacement or a credit, as agreed in advance. Not both. Media bookings follow their own cancellation terms.

Frequently asked questions

No. We do not mention returns, payback periods or subsidies. The assessment and advice remain with you.
