Sales Agent – United Kingdom (freelance

Nexio Projects is looking for an independent, full-cycle Sales Agent to develop new business in the UK. You will introduce Nexio’s sustainability advisory and implementation services to relevant organisations, develop trusted relationships with senior stakeholders, and manage opportunities from first conversation through to signed engagement. This role is suited to either an experienced sustainability professional with a strong UK network or a commercially minded business development professional with experience in Eco Vadis, climate, ESG, consulting, or another complex B2B services environment.

We help people and organizations take their next steps towards a more sustainable future. Day to day, that means cutting through the complexity of sustainability management and reporting so our clients can make bold commitments—and act on them.

As a sustainability consultancy of 45+ people headquartered in Rotterdam, we serve hundreds of international mid-market clients across Eco Vadis, B Corp, CDP, CSRD, and net-zero strategy. We're a certified B Corp (the highest-scoring B Corp consultancy in the Benelux), a certified Great Place To Work® and a Platinum Eco Vadis strategic consulting partner. We practice what we advise, and we hire people who combine technical seriousness with a light touch: human, humble, hardworking, and allergic to taking themselves too seriously.

This is an independent, commission-led opportunity rather than an employment role. It is suited to entrepreneurial, ambitious salespeople who want the flexibility to develop their own market and earn based on the business they generate. If you're driven by results and care about sustainability, we'll give you the platform and flexibility to own your success.

• Lead business development in the UK for our sustainability consulting services, focusing on Eco Vadis support, SBTi support, and product carbon foot printing

• Turn high-potential prospects into long-term clients across packaging, manufacturing, logistics, chemicals, FMCG, and professional services

• Pitch tailored sustainability solutions to procurement teams, sustainability leaders, and executives

• Own the full sales funnel, from first outreach to close. Our team will provide technical support on proposals, but you are in charge of the process.

• Stay on top of carbon accounting (including the GHG Protocol and SBTi), ESG standards, and the Eco Vadis platform

• Work with marketing to strengthen lead generation and keep messaging in line with what the market needs

• Hand deals over smoothly to our consultancy and account management teams

• At least 5 years of proven B2B sales experience, ideally in consulting, sustainability, or ESG services

• Fluent in English; any additional European language is a plus

• A solid understanding of corporate sustainability, including carbon accounting, supply chain ESG, and ratings like Eco Vadis

• A natural relationship builder who speaks the language of procurement teams, sustainability leads, and executive decision-makers

• Strong commercial instinct, and comfortable navigating complex sales cycles

• Comfortable working independently and remotely, while staying connected to an international team

• Organised, results-oriented, and at home in fast-paced, entrepreneurial environments

• Comfortable managing Hub Spot, maintaining an accurate pipeline, and working towards clear commercial objectives.

Above all, you care about sustainability and want your work to make a positive impact.

• You’re self-employed: we work together under a sales agent agreement, not an employment contract, so you’re free to represent non-competing services alongside us

• You earn an uncapped percentage commission on eligible new business that you directly develop and help close

• Your territory will focus on UK-based mid-market and larger organisations, particularly in sectors such as manufacturing, packaging, logistics, chemicals, FMCG, and professional services

• This is a fully remote role open to candidates based anywhere in the United Kingdom. The listed city is for administrative and job-posting purposes only and is not the required work…
