✅ Our recommendation: Sign, with reservations
The quote from Quatt is priced in line with the market, transparently structured and supported by a strong customer reputation (4.5/5 from 1.026 reviews). Before you sign, we recommend requesting the general terms and conditions of sale and having it confirmed in writing that the total of €6.175 includes VAT. Also, before accepting the Installation Plan, establish how Quatt handles any structural damage during installation (feed-throughs in the bicycle shed, kitchen and knee wall), as the quote contains no clause on this.
The quote shows three clear lines: Quatt Hybrid €5.974, extra piping €250 and a home-visit discount of -€49. The total of €6.175 is clearly built up without hidden provisional items.
Subsidy arranged by Quatt
Quatt arranges the subsidy application (ISDE, €2.125) after installation. This fully takes the work off your hands and is a concrete benefit. Net, you pay approx. €4.050 after subsidy.
Good reputation and reviews
Quatt scores 4.5/5 based on 1.026 reviews. This gives a good picture of other customers' experiences with installation and service.
Detailed installation plan
The quote specifically describes how the pipes will be routed (via the bicycle shed, kitchen and knee wall to the boiler cupboard). This minimises discussion afterwards about the extent of the work.
Technical specifications present
COP A7W35 4.9, capacity 6kW, sound level 52-55 dB(A) and registration code KA21789 are stated. This makes technical comparison with alternatives possible.
VAT not explicitly broken out
The quote total of €6.175 does not state whether it is incl. or excl. VAT. For VAT-liable services this is a point of attention. Ask Quatt to confirm that this is a VAT-inclusive amount.
Payment before installation — cash-flow effect
You pay the full amount (€6.175) on acceptance of the Installation Plan, before installation. You receive the subsidy (€2.125) only after installation. You temporarily advance €6.175.
General terms and conditions not attached
The quote refers to general terms and conditions of sale but does not include them. Request the terms before signing — in particular the clauses on cancellation after acceptance of the Installation Plan and on liability.
No warranty on labour mentioned
A '24-month product warranty' is offered, but no warranty on the installation labour. Ask for confirmation of the warranty period on the installation work carried out.
Accepting the Installation Plan = irrevocable payment obligation
As soon as you accept the Installation Plan (via the payment link), the purchase agreement is concluded. Cancellation is then no longer possible under this quote. It is not stated what happens if installation proves technically impossible after payment but before installation (apart from a vague reference to refunding the 'deposit').
No liability arrangement for structural damage
The installation requires several feed-throughs (bicycle shed, kitchen, knee wall). The quote contains no clause on liability for damage to the home during the work. Have this recorded in writing with Quatt before agreeing.
