Sustainable cleaning pioneer awarded one of the first Royal Warrants from King Charles III

Delphis Eco, a British innovator in sustainable cleaning solutions, has been awarded one of the first Royal Warrants issued under the reign of King Charles III. The honour reflects the company’s longstanding commitment to high product performance and environmental stewardship, as well as its service to the Royal Household.

The recognition places Delphis Eco among the inaugural cohort of manufacturers granted warrants in the new reign, marking a continuation of the brand’s relationship with the Royal Family. The company had previously held two Royal Warrants, from HM Queen Elizabeth II and from the then Prince of Wales.

Commitment to performance and sustainability

The Royal Warrant highlights the stringent standards that must be met by suppliers, from product quality to environmental responsibility. For Delphis Eco, it serves as validation of its ongoing mission to redefine professional cleaning through sustainable alternatives.

“We are deeply honoured and proud to be awarded the Grant of Royal Appointment to HM The King within these first Royal Appointments,” said Mark Jankovich, Founder & CEO of Delphis Eco.

“It is especially meaningful for us as we know what the Warrants stand for. These are only granted for exceptional product performance, deep sustainability ethos and unwavering service. HM The King is passionate about sustainability, and we are truly delighted to be of service to him and his household.”

A leader in eco-friendly innovation

Delphis Eco was an early pioneer in bringing sustainable cleaning products to the professional market. The company was the first in Europe to use 100% recycled plastic packaging for its product range, a move that anticipated industry-wide shifts toward circular economy practices.

Its cleaning solutions are plant-based, vegan, biodegradable, and designed to be non-harmful to users and the environment. By focusing on both performance and ecological impact, the company has carved out a reputation for providing one of the most environmentally friendly professional cleaning ranges available.

The company’s dedication to sustainable packaging aligns with global efforts to reduce plastic waste. According to the Ellen MacArthur Foundation, only around 9 percent of plastic is recycled globally, highlighting the scale of the challenge. By adopting fully recycled and recyclable packaging, Delphis Eco demonstrates how manufacturers can take proactive measures that support both waste reduction and resource efficiency.

Royal endorsement and wider impact

The Royal Household’s continued use of Delphis Eco’s products in its kitchens and housekeeping departments underscores the products’ efficacy in demanding settings. Royal Warrants are traditionally seen as a mark of trust and quality, but under King Charles III they also reflect his long-standing commitment to environmental sustainability.

As Prince of Wales, King Charles championed causes ranging from organic farming to climate action. His reign has already signaled that sustainability will remain a key theme, and the granting of warrants to companies like Delphis Eco reinforces this direction.

For businesses, the recognition signals a growing expectation that suppliers demonstrate measurable progress on sustainability alongside product performance. The Royal Warrant system now serves not only as a mark of prestige but also as a benchmark for responsible business practices.

Broader sustainability context

The professional cleaning sector is undergoing significant transformation, driven by tightening regulations, customer demand for greener solutions, and the urgency of reducing chemical and plastic pollution. Conventional cleaning products have long relied on harsh chemicals that can affect indoor air quality, human health, and ecosystems when disposed of improperly.

Plant-based formulations like those offered by Delphis Eco represent a growing segment of the industry. Market research firm Allied Market Research projects the global green cleaning products market will surpass USD 110 billion by 2031, expanding at a compound annual growth rate of more than 10 percent.

Within this landscape, companies that demonstrate both innovation and accountability are likely to find new opportunities, particularly in sectors such as hospitality, facilities management, and government procurement, where sustainability criteria are becoming more deeply embedded in purchasing decisions.

Looking ahead

Delphis Eco’s Royal Warrant comes at a time when businesses across industries are under pressure to reduce their environmental impact and prove the integrity of their sustainability claims. By aligning product innovation with circular economy principles and demonstrating results through long-standing customer relationships, the company sets a model for peers in the manufacturing and consumer goods sectors.

The Royal endorsement not only strengthens Delphis Eco’s position in the market but also highlights the role that recognition and accountability can play in accelerating the adoption of sustainable practices across industries.

As Jankovich emphasised, “HM The King is passionate about sustainability, and we are truly delighted to be of service to him and his household.”

The award marks a milestone for Delphis Eco and a signal of the values that will define Royal Warrants under King Charles III: excellence, responsibility, and a commitment to a more sustainable future.
