If you’re looking into WECA green business grants, the two currently available (as of August 2026) are Green Community Building Grants, for not-for-profit organisations running community facilities and Green Care Home Grants, for SMEs and charities operating care or nursing homes. Both offer £1,000-£15,000 towards energy efficiency and low carbon improvements, and both include a free energy survey as part of the application process.

Green Community Building Grants help not-for-profit organisations purchase and install equipment that reduces emissions, cuts utility costs and improves energy efficiency in the community facilities they run.

Who’s eligible:

Libraries, parks, GP surgeries, post offices, pubs, retail spaces and sports facilities aren’t eligible buildings, and general businesses, sole traders and partnerships aren’t eligible applicants – this scheme is specifically for the not-for-profit sector.

Funding rate:

£1,000-£15,000, covering 30%, 40%, or 60% of eligible costs depending on the measure (see below) or, for measures outside the standard list, based on the project’s simple payback period without grant.

If your organisation is based specifically within Bristol, it’s also worth checking the Bristol City Leap Community Energy Fund – a separate, Bristol-only scheme (funded by Ameresco and Vattenfall) offering grants, microgrants and zero-interest loans for community-led decarbonisation projects. Its eligibility criteria differ in places from Green Community Building Grants above – libraries, for instance, are explicitly welcome to apply to City Leap, but explicitly excluded from Green Community Building Grants – so it’s worth checking both if you’re not sure which fits.

Green Care Home Grants help SMEs and charities operating care or nursing homes make the same kind of energy efficiency and low carbon improvements.

Who’s eligible:

Funding rate:

£1,000-£15,000, covering up to 50% of eligible costs – a single flat rate rather than the tiered structure above.

Both schemes fund similar categories of work:

Both have real technical strings attached worth knowing before you apply: only low carbon heating technologies qualify (heat pumps, electric radiant heating, solar thermal – not gas, oil, coal, or LPG, even as part of a hybrid system), heat pumps and air conditioning must use R32 or a lower-GWP refrigerant, and renewable generation projects are generally expected to address the cheaper electricity-reduction measures first. Neither grant can be used for anything not recommended by an independent assessment, for projects that don’t produce measurable carbon savings, or for costs that form part of a wider deep renovation. Full technical criteria are set out in each scheme’s grant guidance.

Every applicant needs an independent assessment of their premises – but you don’t need to pay for one separately. WECA’s Technical Advisors provide a free energy survey as part of the application process, typically involving around 12 hours of support:

If you’ve already had a survey from someone else and it supports what you want to apply for, you can skip WECA’s survey entirely and go straight to the project application.

For a straightforward project, WECA’s free survey is often all you need. But for anything more complex – like a heritage building or a multi-property portfolio where the right answer isn’t obvious – a general walkaround survey may not give you (or WECA’s assessors) enough to work with. That’s where specialist technical testing and feasibility work make a real difference to the strength of an application.

The application process is broadly the same for both schemes:

  1. Complete an expression of interest form – WECA carries out eligibility and due diligence checks, including a credit check.
  2. Book in an energy survey – free, unless you already have an independent report that supports your application.
  3. Complete your project application form – you’ll need one recent quote to calculate the grant amount and carbon savings.
  4. Application assessment and award – applications are scored competitively against value for money, deliverability, and financial viability (plus, for care homes, resident and staff wellbeing).
  5. Complete your project and claim your grant – the grant is paid in arrears once the project is finished, operational, and paid for.

All projects must be completed, paid for, and claimed by 31st of March 2027, when funding closes – this is a hard deadline that can’t be extended, so it’s worth allowing plenty of time, particularly if you need an energy survey first.

What’s Next?

Whether you’re weighing up a heat network against individual heat pumps, or need heritage-sensitive diagnostics that a standard survey can’t provide, the right technical evidence is often what separates a strong grant application from a shaky one. We can help with the testing and feasibility work that goes beyond WECA’s free survey when a project genuinely needs it.
