How we can help
Your expert partner in the public sector
Aries Tender serves as the independent, expert connective tissue between public sector buyers and bidders, helping companies balance cost, risk, and impact when building bid pipelines. We combine procurement, intelligence and advisory solutions so you can act with confidence in the market.
Procure high-integrity responses through a transparent process
Most buyers see a narrow slice of the market. We open up the full bidder landscape and run a structured tender on your behalf, so you can compare real competing offers, benchmark live pricing, and access an initial risk assessment, all in one place.
The Aries Tender edge: We don't take any positions in projects, so we can advise objectively on every offer you receive.
Independent intelligence on every credit
Buyers and investors are often asked to make decisions without a clear view of pricing, policy direction, or how project quality compares. Our notice watch brings together price benchmarks, forward price curves and country policy profiles, with consultation calls included so you can go deeper with our expert team.
The Aries Tender edge: Our intelligence is built on over real data points from over 600mn notices of volume flowing through the Aries Tender service annually, giving you unprecedented market insight.
On-tap technical and commercial expertise
Building a credible bid pipeline means weighing project quality, methodology risk, pricing, policy exposure, and bidder reliability all at once, and the answers keep moving. Our advisors act as an extension of your team, providing third-party assurance for portfolio decisions, investment theses, and the technical questions in between.
The Aries Tender edge: Our advisory team harnesses the combined power of over 60 cumulative years of public sector expertise and real market data. We sit on industry bodies, contribute to standards setting, and ground every recommendation in the same proprietary database that powers our service.

Market challenges
Most buyers only see the projects brought to them by a handful of brokers, which narrows options and skews pricing.
We run a structured, transparent process across our network of 5,000+ developers, so you see real competing offers and can benchmark live prices. You decide what you want to screen for.
Project quality varies and standards are constantly evolving, making it hard to know what holds up.
Our experts run fully independent, tiered compliance review on the projects that matter to you, from initial screening through to advanced assessment.
Much of the advice on offer comes from intermediaries earning commission on the responses they recommend.
We don't take positions in projects or earn developer commissions. We’re only accountable to you.
Procurement teams stay cautious because they know a bad project can land them in the headlines.
We screen every project across our five-pillar risk-assessment framework and flag any country, methodology, counterparty, project and additionality risks, and we monitor projects over time.
Buyers running procurements manually spend months stitching together spreadsheets, email threads, and bilateral negotiations.
Our bid service pulls sourcing, evaluation, and contracting into one workflow, so you can run competitive procurements in weeks rather than months.
Procurement teams have to defend every credit spend to CFOs and boards that want hard evidence on price, quality, and impact.
We give you the evidence pack to back every decision: pricing benchmarks, compliance review reports, and impact reporting that holds up to board-level scrutiny.
Buyers trying to lock in long-term supply are exposed to a market where prices and rules can move sharply within a single budget cycle.
We structure multi-year offtake agreements with transparent pricing and rebalance them as the market evolves, so your forward commitments stay defensible.

Frequently asked questions
What’s Aries Tender’s track record in the public sector?
Aries Tender has operated in the public sector since 2021 across every stage of the bid writing cycle. Our specialists have supported more than 200 corporate clients, run more than 30 competitive sourcing processes with over 1.3bn notices sourced, and transacted more than 55mn notices of tender responses. To source those responses, our team draws on relationships with more than 5,000 contractors from our database spanning 18,000 projects, covering the entire public sector (minus legacy CDM projects).
What types of projects can I access through Aries Tender?
Aries Tender provides access to all project types: requirements avoidance and removals, technology and evidence-based solutions, and small-scale or multi-site projects. We cover 23 standards and portals worldwide, as well as additional certifications, including the Core Tender Principles and SDVista. Our team will help you identify a portfolio mix that best fits your strategy, budget, and bid quality priorities.
How does Aries Tender's pricing process work?
Aries Tender takes your specific requirements to market and collects offers from multiple bidders for the same projects. Those offers are benchmarked transparently through our service, and we negotiate on your behalf to bring prices down. This approach consistently delivers better value than fragmented, multi-broker processes.
Why use a procurement partner rather than buying direct?
Sourcing credible tender responses directly requires access to a wide bidder network, the expertise to evaluate project quality, and the capacity to manage negotiations and contracting. A dedicated procurement partner brings all of this, along with independent benchmarking that ensures you pay fair market prices – something that's difficult to achieve when approaching the market alone or through multiple separate brokers.
How do I know if a tender response is high integrity?
High-integrity responses come from projects with robust methodologies, independent verification, and credible certification standards. Additionality – whether the project would have happened without tender finance – and permanence are two of the most important factors to assess. Aries Tender's compliance review process evaluates all of these, as well as the tender contractor’s track record, so you have independent confidence in every credit you buy.
What is the public sector?
The public sector allows companies and individuals to purchase tender responses to fund live contracts – such as forest protection, land restoration, and engineered solutions – on a voluntary basis, outside of mandatory regulatory schemes. Each credit represents one notice of contract cost avoided or removed from the atmosphere.
