Overview
Wattler is a Hungarian energy company that positions itself as a smart natural gas supplier for businesses. According to its official website, it provides natural gas supply, electricity supply and energy-efficiency services, with a stated mission of making small and medium-sized enterprises more competitive through its energy offerings. The company says it serves several hundred customers and supplies natural gas nationwide, covering consumption levels from one thousand to several million cubic metres per year. The brand name is explained on the company's own about page as a combination of two words: "Watt", the unit of power from which energy is derived, and "butler", the servant who assists with versatility and deep knowledge. This naming reflects the company's self-image as an expert, service-oriented energy partner rather than a pure commodity supplier. Wattler's core commercial activity is natural gas supply. It markets a discounted gas offer aimed at small consumers and fixed-price gas offers for SMEs, and it allows customers without remote-reading meters to submit their readings through its app so that they pay only for actual consumption. Alongside gas, the company offers electricity supply and a range of energy-efficiency and audit services. These include energy specialist (szakreferens) services, large-enterprise and exploratory energy audits, audits and certification for the Factory Rescue Programme, the Energy Efficiency Obligation Scheme (EKR) and TAO tax-benefit eligibility, building energy certification, and other consulting. The company is led by managing director and co-founder Németh Ders, who states that he has worked in the energy sector since 2009 in Hungary, Switzerland and Croatia, with experience in strategic planning, deal structuring, negotiation and contracting, trading and hedging, and retail and sales. The team includes energy traders, gas-market data analysts, customer relations staff and administrative personnel. Wattler is a private company and, based on the available evidence, operates primarily in the Hungarian market.
History
Wattler is a Hungarian energy company whose public history is documented mainly through its own website. The company name is a portmanteau of "Watt" and "butler", reflecting its ambition to act as a knowledgeable, multi-skilled energy servant to business customers. The company was co-founded by Németh Ders, who serves as managing director and states that he has been active in the energy sector since 2009, working in Hungary, Switzerland and Croatia. His background spans strategic planning, deal structuring, negotiation and contracting, trading and hedging, and retail and sales, with a primary focus on natural gas and some exposure to the electricity market. According to the company's own account, the motivation for founding Wattler came from the observation that the energy industry lags significantly behind other innovative sectors, causing difficulties and losses for both companies and consumers. The founders believed that solutions already exist and simply need to be implemented, and they created Wattler to pursue that goal. Wattler has built its business around natural gas supply for businesses, complemented by electricity supply and energy-efficiency services. It markets itself as "the smart natural gas supplier for companies" and says it serves several hundred customers nationwide, with annual consumption ranging from one thousand to several million cubic metres. The company has developed an app that allows customers without remote-reading meters to submit their own readings, so they pay only for actual consumption. It also offers a discounted gas product (Diszkontgáz) aimed at small consumers and fixed-price gas offers for SMEs. Beyond supply, Wattler has expanded into energy-efficiency and audit services. Its service list includes energy specialist (szakreferens) services, large-enterprise and exploratory energy audits, audits and certification for the Factory Rescue Programme, the Energy Efficiency Obligation Scheme (EKR) and TAO tax-benefit eligibility, building energy certification, and other consulting. This combination of supply and advisory work positions the company between a traditional energy retailer and an energy consultancy. The available evidence does not specify Wattler's exact founding year, ownership structure or any stock listing. It appears to be a privately held company operating primarily in Hungary. Its team, as listed on its website, includes energy traders, gas and energy market data analysts, customer relations staff and administrative personnel, alongside the managing director.
