Landlord installing new boiler while in points dispute

Landlord has been notified of a dispute in points. Their response was not only to dispute my version of the points, but also to advise me that I must not prevent their installing of a new boiler next week. The boiler is probably going to improve the energy rating, giving them a better margin of points to make up for any points the commission doesn’t agree with. The Huurcommissie will probably not make its inspection before this happens. My question is whether I can refuse the installation while waiting for the inspection. Your thoughts?
