Halton Foundation Grant Programme 2026: Up to US$30,000 a Year for Nonprofit Research on Indoor Air Quality, Thermal Comfort, and Occupant Health

Halton Foundation Grant Programme 2026: Up to US$30,000 a Year for Nonprofit Research on Indoor Air Quality, Thermal Comfort, and Occupant Health

Most people spend the overwhelming majority of their lives indoors — at home, at school, at work, in hospitals and public buildings. Yet the quality of the air we breathe inside, the temperature and humidity we sit in for hours, and the ways those conditions affect concentration, sleep, and long-term health are still poorly understood in many settings. The Halton Foundation Grant Programme exists to close that gap. It gives non-profit organizations around the world money to study indoor environmental quality (IEQ) and to develop practical ways to improve it.

For the 2026 cycle, the programme accepts applications from 1 July 2026 through 1 September 2026, with funding decisions announced on 1 November 2026. Grants run up to US$30,000 per year, and both single-year and two-year projects are supported. This guide explains what the grant funds, who is eligible, how the review works, and how to put together an application that a scientific review board will take seriously.

Key Details at a Glance

Always confirm the current window and requirements on the official page before you begin, because dates and portal links can change from cycle to cycle.

What the Grant Funds

The Halton Foundation supports research and practical projects that improve the environments people occupy indoors. According to the foundation, fundable work addresses three connected areas:

• Indoor air quality — measuring, understanding, and reducing pollutants, particulates, ventilation problems, and airborne contaminants inside buildings.
• Thermal conditions and comfort — how temperature, humidity, and airflow affect the people who live and work in a space.
• Occupant health and human wellbeing — the downstream effects of indoor conditions on illness, comfort, productivity, and quality of life, including “IEQ-linked illness.”

The programme is deliberately broad about the type of building and the part of the world involved. It funds research across North America, Europe, Asia, “and beyond,” and it welcomes both investigative studies (measuring a problem and understanding its causes) and solution-oriented projects (organizations that “develop solutions aiming for better indoor environmental quality”). What ties every fundable project together is a direct, demonstrable connection to indoor environmental quality. A proposal that only touches IEQ tangentially — for example, a general public-health campaign that happens to mention air — is a weak fit. A proposal that puts IEQ at the center is a strong one.

Grants can be structured as single-year awards or as multi-year projects lasting up to two years, depending on the scope of the work. If your research genuinely requires two seasons of monitoring, a phased build-and-test cycle, or a longitudinal look at health outcomes, the two-year option lets you plan realistically instead of compressing everything into a rushed twelve months.

The Money: Grant Size and the 10% Overhead Rule

Awards go up to US$30,000 per year. Smaller amounts are common — the foundation describes grants ranging “from thousands to $30,000 USD annually” — so you should request what your project actually needs and can justify, not simply the ceiling.

The single most important budgeting rule to internalize is the overhead cap: no more than 10% of total project costs may be allocated to administrative and overhead expenses. The foundation is emphatic that this is “non-negotiable” and applies to every successful applicant “with no exceptions.” Practically, that means at least 90 cents of every dollar has to go toward the direct work — equipment, sensors, lab analysis, field measurement, participant costs, data collection, and the researcher time tied directly to the project — rather than institutional indirect-cost recovery.

This rule matters a great deal for university applicants, because many universities apply standard indirect-cost rates that far exceed 10%. Before you submit, talk to your grants or sponsored-programs office and confirm they will accept the 10% cap for this funder. A budget that quietly assumes a 40% or 55% indirect rate will not comply, and reviewers who see it will read it as a sign that the applicant did not read the guidelines. Build your budget from the direct costs up, keep overhead within the limit, and state clearly in your budget justification that your institution has agreed to the cap.

Who Can Apply

Eligibility is defined by organization type, not by discipline or country:

• Eligible: Non-profit organizations, including universities, research institutes, registered charities, and NGOs. The foundation states plainly that “universities, research institutes, registered charities, and NGOs are all eligible to apply.”
• Not eligible: For-profit organizations. “Commercial companies and for-profit entities cannot apply.” This is a firm line — a commercial manufacturer, consultancy, or startup cannot apply directly, even if its work relates to indoor air.
• Geographic scope: Worldwide, with “no geographic restrictions.” Applicants from any region are welcome.

If you are an individual researcher, you generally apply through your host institution — the non-profit university or research institute that will administer the grant — rather than as a private individual. If you are part of a coalition that includes commercial partners, the applicant of record and the recipient of funds must be the non-profit entity.

Because the foundation is connected to Halton, a company active in indoor-air and ventilation technology, applicants sometimes wonder whether the grant favors work that promotes particular products. The programme is framed as a charitable research fund focused on the public good of better indoor environments. Keep your proposal independent and evidence-driven; propose the study that answers a real question, not one designed to validate a specific commercial solution.

How Applications Are Reviewed

Applications are assessed by a review board during September and October 2026, with decisions released on 1 November 2026. The evaluation weighs several factors:

• Scientific merit — is the study well-designed, methodologically sound, and likely to produce reliable findings?
• Relevance to indoor environmental quality — does the project sit squarely within the foundation’s focus areas?
• Potential health and wellbeing impact — will the work meaningfully improve, or improve our understanding of, occupant health?
• Feasibility of achieving measurable results — can the team realistically deliver the outcomes within the budget and timeline?

Notice how much weight sits on measurable results and feasibility. Reviewers are not looking for the most ambitious-sounding project; they are looking for the project most likely to actually finish and produce usable evidence. A tightly scoped study with clear metrics, a credible timeline, and a team that can plainly do the work will beat a sprawling proposal that promises everything and specifies nothing.

Required Application Materials

The core of the application is a detailed project proposal. The foundation asks that it include:

• Objectives — the specific questions or goals the project will address.
• Methodology — how you will do the work: study design, measurement approach, instruments, sample or site selection, and analysis plan.
• Expected outcomes — what you expect to learn or produce, stated in concrete, measurable terms.
• Timeline — a realistic schedule that fits within a single year or, for larger projects, up to two years.
• A clear budget — a line-by-line breakdown of how the funding will be used, with overhead held to the 10% maximum.

Applications are submitted through the foundation’s online portal, which is linked from the official grant page during the open window. Because the portal opens on 1 July and closes on 1 September, do not wait until late August to start — give yourself time to gather institutional sign-off on the budget and the overhead cap, which is often the slowest step.

How to Write a Competitive Proposal

A few principles separate fundable proposals from forgettable ones in a small, focused programme like this one:

Lead with the IEQ connection. In the first paragraph, make it unmistakable how your project improves indoor air quality, thermal comfort, or occupant health. Do not make reviewers hunt for the relevance.

Make outcomes measurable. Replace vague aims (“raise awareness,” “improve conditions”) with specific, quantifiable targets: pollutant concentrations measured before and after an intervention, a validated sensor deployment across a defined number of rooms, health or comfort survey results from a stated population, or a dataset made openly available. If a reviewer cannot picture how you will prove success, the proposal reads as feasible-but-unverifiable.

Right-size the scope to the budget. With a ceiling of US$30,000 a year and a hard overhead cap, this is not the grant for a massive multi-site trial. Design a project that fits the money. A focused study done well is far more competitive than an over-scoped plan that clearly needs three times the funding.

Build the budget from direct costs. List the equipment, analysis, field costs, and researcher time that do the actual work, then confirm overhead stays at or below 10%. Get your finance office to agree in writing before you submit.

Show the team can deliver. Briefly establish that the people involved have the skills, access to sites or facilities, and time to complete the work within the timeline. Feasibility is an explicit review criterion, so treat it as one.

Plan for dissemination. Say what happens to the findings — a publication, an open dataset, a practical guideline, a tool other organizations can use. A charitable research funder wants public benefit, so make the path from your results to real-world impact explicit.

Common Mistakes to Avoid

• Ignoring the 10% overhead cap. This is the most frequent disqualifier. A budget assuming a standard university indirect rate does not comply. Fix it before submission.
• Applying as a for-profit entity. Commercial companies cannot apply. If your project involves a company, the non-profit partner must be the applicant and fund recipient.
• Weak or missing measurable outcomes. Proposals that cannot state how success will be measured struggle against the “measurable results” criterion.
• Over-scoping. Asking for more work than US$30,000 a year can support signals a mismatch between ambition and resources.
• A thin methodology. Reviewers judge scientific merit; a proposal that skips how the work will actually be done reads as unserious.
• Starting late. The window runs only from 1 July to 1 September. Institutional budget approvals and letters can take weeks — begin early.

Timeline for the 2026 Cycle

• 1 July 2026 — application portal opens.
• 1 September 2026 — application deadline.
• September–October 2026 — board review of submitted proposals.
• 1 November 2026 — funding decisions announced.

If your project is not ready this year, the programme runs on an annual cycle, so it is worth monitoring for the next round and preparing in advance.
