Enertek International GmbH Cologne

Consultancy, Contract Development and Testing Services

Enertek International GmbH assists participants in the heating and cooking appliance industry with research and development services covering all aspects of the product life cycle.

The company, based in Cologne and managed by Kellie Melbaum-Brenner, provides consultancy, contract development and testing services to European clients from its base in Germany. In addition to its own resources the company has access to the laboratory and design facilities offered within its sister company and wider group.

Enertek International GmbH has been incorporated to offer European appliance manufacturers in the heating, cooling and catering appliance industries access to the same services available to UK and non EU clients without the complications caused by Brexit.

Since Brexit, dealing with companies in the UK has become challenging and poses bureaucratic barriers which can be complicated to overcome.

Dealing with Enertek International GmbH avoids these complications, because any assistance from the UK sister company is dealt with internally. Services to European clients will be undertaken within the single market, under European Law and all commercial activities will be between Enertek International GmbH and the client.
