Summary

[Installation company] offers a hybrid heat pump installation (WeHeat Flint P40, 4kW) for €7.588,82 incl. VAT, with a net investment of €5.464 after an indicative subsidy (ISDE) of €2.125. The quote is formally fairly complete, but lacks unit prices, warranty provisions and attached general terms and conditions, while several items will only be finalised after a technical survey. The mediocre Google reputation (3.7/5) and an internally contradictory subsidy amount call for extra due diligence before signing.

Average score

⚠️ Our recommendation: Complete first, then sign

The quote from [Installation company] contains a reasonable product at a market-conform price, but you are currently signing up to general terms and conditions you have not seen, and no warranty provision on labour or materials is included at all. In addition, the ISDE subsidy amount is internally contradictory (€2.125 vs €2.775) and optional items can substantially increase the final price. Before signing, request the general terms and conditions, have the warranty periods confirmed in writing, clarify the exact subsidy amount, and have the expected additional costs after the survey estimated indicatively.

Findings

Company details fully present

Chamber of Commerce number ([KVK]), IBAN, address, telephone number and email are stated. The quote is traceable and formally correct.

VAT transparently broken out

€6.271,75 excl. VAT + €1.317,07 VAT (21%) = €7.588,82 incl. VAT. The calculation is correct and clearly presented.

Itemised product list with registration code

The WeHeat Flint P40 Monobloc 4kW with registration code KA28647 is listed, including indoor unit, 50L buffer tank, Honeywell thermostat and Caleffi separator. This makes the ISDE subsidy application verifiable.

Payment schedule reasonably structured

50% on order, 40% on delivery of materials, 10% after completion. The 10% final payment after handover provides some financial leverage in the event of incomplete delivery.

Member of Techniek Nederland, certified installer

[Installation company] is a member of Techniek Nederland (the Dutch installation industry association) and listed as a certified installer. This is a positive quality indicator for heat pump installations.

Contradictory ISDE subsidy amounts

The quote states an ISDE indication of €2.125, but the technical specification sheet states €2.775 as 'application pending'. This €650 difference is unexplained and may affect your net investment. Ask for written confirmation of the exact subsidy amount.

General terms and conditions not attached

By signing, you declare that you agree to the general terms and conditions of [Installation company], but these are not attached to the quote. Request the terms before signing.

No unit prices per item

The quote shows a total price but no breakdown per component (e.g. the WeHeat Flint P40 separately, installation costs separately). This makes it impossible to compare or negotiate individual items.

Scope may change after technical survey

The quote is explicitly 'subject to a technical survey'. Several items (consumer unit, bypass, manifold, extra pipework, concrete drilling) are optional and may be added as additional work after the survey, without the total price being fixed now.

No warranty period on labour or materials

There is no mention whatsoever of a warranty on the installation or the WeHeat products. For an investment of €7.588 this is a serious contractual risk. Have at least 2 years' warranty on labour and WeHeat's manufacturer's warranty (typically 5 years) recorded in writing.

Mediocre Google reputation (3.7/5)

Based on 52 Google reviews, [Installation company] scores 3.7/5. This indicates a mediocre reputation. The quote itself mentions 4.5/5, but that is not the external Google score. Request at least 2 recent references for comparable heat pump installations.
