Installer's liability in the event of increased gas bill

Questioner

I have received the annual accounts from Nuon, gas consumption has doubled, the problem is that the boiler is incorrectly adjusted, I do have a maintenance contract with the installer, can I now hold him liable for the extra costs?

Lawyer

I advise you to send a letter to your installer stating that he must adjust your boiler correctly within a period of 7 days. Furthermore, you write in the same letter that you reserve the right to terminate the agreement and that you hold him liable for the damage you have suffered and will suffer. You can recover the higher gas bill, which is the result of your installer's error, from him. On the website you will find the sample text of a standard notice of default (link to the sample letter: http://www.rechtswinkel.nl/documenten/7/ingebrekestelling.html). You can use this text for the most part for your letter.

Lawyer

You can hold the installer who did the maintenance liable for the costs. This if you can irrefutably, i.e. with proof, measure that the error really goes with that. I would be happy to assist you with this.
