You can claim a one-off grant of up to €475 per meter (including VAT) for the removal of your night night-only meter,. This amount is intended to cover the costs of your electrician and the inspection body.
The premium can be claimed once your electricina has done the adaptations to your electrical installation (more information on the steps to follow).
Keep your electrician's invoices carefully so that you can benefit. If the invoice covers several meters, make sure that the electrician clearly states on the invoice which meter(s) he has adapted.
