Use your heating safely thanks to the maintenance contract
GOK from Amsterdam offers maintenance and service contracts for businesses, owner-occupiers' associations and private persons. We are mainly active in the provinces of Noord-Holland, Utrecht and northern Zuid-Holland. GOK is also the right party to replace your gas appliance.
The GasOnderhoudsKombinatie B.V. maintenance contract entitles you to annual maintenance and servicing. Do you require someone to come by because of a defect? You will receive a standard reduced rate on wage costs and the house call. In order to be sure whether we really need to come by, please first do the check.
If you add a service module to the maintenance contract, house calls and wages will be free of charge. So you know exactly what to expect. This applies to all defects within the casing of the contracted appliance. However, it is important that you first complete the defects checklist.
Is your gas appliance outdated or defective? GasOnderhoudsKombinatie B.V. is also the right party to replace your gas appliance. Register here immediately to replace your gas appliance.

Maintenance contract first time visit
When visiting a customer for the first time, GOK will charge a one-off house call fee, the costs of materials used and the wages if the call takes more time than a regular maintenance visit. The first year will be charged in full irrespective of the commencement date of the maintenance contract. During that year, a maintenance visit will be made.
Service module first time visit
In the case of a service module, only that part of the year will be charged that has yet to lapse. This will be calculated per quarter.
As a result of the heavily increased parking rates in Amsterdam and the surrounding area, we are unfortunately obliged to pass on the parking costs to our customers where the defect service and installation activities (not in the case of annual maintenance inspections) are concerned.
If we notice during our visit that one of the above details is incorrect, GasOnderhoudsKombinatie B.V. is entitled to adjust these for invoicing purposes.
