For businesses buying enquiriesHeat pump leads in the Netherlands

For heat pump installers who want enquiries from homeowners considering a hybrid or fully electric heat pump.

Which enquiries you receive

The applicant wants a heat pump assessed and quoted for their own home. Sometimes the choice between hybrid and fully electric has been made, sometimes advice is wanted. The existing heating and the insulation situation have been discussed by phone.

Enquiries for hybrid or fully electric heat pumps.

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
  • Property type and existing heating
  • Insulation situation 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.

  • Existing heating, for example a gas boiler and its approximate age
  • Property type and construction period
  • Insulation situation as described by the applicant
  • Preference for hybrid, fully electric or no preference yet
  • Budget indication, or a note that the budget is still to be defined

What you do not receive

  • Requests about subsidies only, with no interest in a quote
  • Tenants without the owner's permission
  • Servicing or faults on an existing heat pump
  • Projects outside the agreed service area

Please note: An ISDE subsidy may be available under the conditions in force at the time; Klantwerf makes no commitment about it. Technical suitability and sizing are for the installer to determine. A budget still to be defined is not a confirmed budget.

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 discuss insulation by phone and record what the applicant tells us. A survey or heat loss calculation remains with you.
