PPAs & Funding

Making Renewable Energy Financially Viable

The biggest barrier to renewable energy isn't the technology - it's the upfront cost.

Solar PV, battery storage and heat pump systems deliver real, long-term savings. But capital expenditure, procurement complexity and uncertainty around available funding can stall projects before they start.

Helix Energy helps organisations structure their energy investment properly. Whether that means a Power Purchase Agreement that removes upfront cost entirely, an ECO4 or Warm Homes Plan grant for social housing, or a blended funding strategy that makes a larger project viable. The team, here at Helix Energy, will identify the right route and manage the process from assessment through to delivery.

We don't offer funding advice in isolation. Every recommendation is built around an energy system we can design and install ourselves, so the finance and the technology are always aligned.

Our PPA & Funding Services

We help clients access the right funding mechanism for their project, then deliver the energy systems those structures are designed to fund.

  • Solar farm in the UK

    Power Purchase Agreements (PPAs)

    A PPA allows you to benefit from on-site renewable energy - typically solar - without owning the system. A third-party investor funds, owns and maintains the installation. You purchase the electricity generated at a fixed, below-market rate for an agreed term. No capital outlay. No maintenance responsibility. Predictable energy pricing from day one.

  • Electricity pylons and wires

    Blended & Developer PPAs

    For larger development schemes, mixed-use sites or multi-tenancy buildings, a blended PPA structures energy supply across multiple end users - combining on-site generation, battery storage and grid import into a single contracted arrangement. We design the system, model the commercial outcomes and support procurement.

  • A newly built warm home

    ECO4 & Warm Homes Plan Funding

    Eligible residential and social housing projects can access grant funding through ECO4 and the incoming Warm Homes Plan to cover the cost of insulation, heat pumps, solar PV and battery storage. We manage the full process - from eligibility assessment and application through to MCS-accredited installation and sign-off.

  • Pipes and thermostat for a new heating system in a home

    Boiler Upgrade Scheme (BUS)

    Homeowners and landlords installing an air source or ground source heat pump may be eligible for a grant under the Boiler Upgrade Scheme. We handle the application as part of the installation process — no paperwork chasing, no separate advisors.

  • Solar panels on a new commercial building

    Commercial Grant & Incentive Assessment

    Beyond PPAs, a range of commercial funding routes exist for energy efficiency and renewable energy — including PSDS, SHDF, LADS and local authority schemes. We assess what your project may be eligible for and build that into the overall energy strategy.

  • Feasibility survey on new development site

    Funding Strategy & Feasibility

    Before committing to any route, we provide an honest feasibility assessment - what's available, what you're likely to qualify for, what the financial model looks like, and how it sits alongside your energy and compliance requirements.

// Why Choose Helix Energy

Experience & Technology All Under One Roof

Most organisations are forced to manage funding advisors and energy installers separately. Advice gets siloed, projects stall and the systems that get built don't always match the funding structure that was agreed.

Helix Energy is different. We combine energy consultancy, system design and MCS-accredited installation in a single team. That means:

✔ Funding routes are assessed against systems we can actually deliver

✔ Technical specifications are built around what funders require

✔ No gap between the advice you receive and the outcome on the ground

✔ A single point of contact from feasibility through to commissioning

Our experience team can take your project from assessment to delivery.

Who We Help With PPAs & Funding

We help clients access the right funding mechanism for their project, then deliver the energy systems those structures are designed to fund.

  • Commercial warehouse

    PPAs for Commercial & Industrial Building

    For businesses and property owners with suitable roof or land space, a commercial PPA can eliminate the capital cost of solar while locking in energy pricing below the grid rate.

    ✔ No upfront investment
    ✔ Immediate reduction in electricity costs
    ✔ Improved ESG credentials
    ✔ Systems designed to your actual load profile

    We model system yield, PPA contract terms and bill savings so you understand the commercial case before committing.

  • Housing association flats

    Funding for Housing Associations & Public Sector

    Social housing providers, local authorities and registered social landlords can access significant grant funding to decarbonise their housing stock -reducing fuel poverty, improving EPC ratings and meeting net zero targets.

    ✔ ECO4 and Warm Homes Plan eligibility assessment
    ✔ SHDF and LADS applications
    ✔ Whole-house retrofit planning
    ✔ MCS-accredited installation and compliance sign-off

    We have direct experience delivering funded retrofit schemes on residential and sheltered housing portfolios.

  • New housing development being built

    Funding for Property Developers Bod

    Developer PPA structures and planning-stage funding assessments can significantly reduce the cost of integrating renewables into new build and mixed-use schemes.

    ✔ PPA structuring for build-to-rent and shared ownership
    ✔ Energy strategy aligned with planning and compliance requirements
    ✔ BNG and ESG considerations factored in from the outset

    When funding is considered at design stage, it changes what's commercially viable.

  • A private home with solar panels on the roof uk

    Grants for Homeowners & Landlords

    If you're installing a heat pump, solar panels or battery storage at home or across a rental portfolio, grant funding may be available to reduce the cost significantly.

    ✔ Boiler Upgrade Scheme (BUS) - up to £7,500 for heat pumps
    ✔ ECO4 eligibility for qualifying households
    ✔ Warm Homes Plan funding as it becomes available

    We handle the application as part of your installation, no separate form-filling or third-party agents.

  • A PPA is a long-term contract between a property owner and an energy investor. The investor funds and installs a solar (or other renewable) system on your building. You agree to purchase the electricity that system generates at a fixed rate - typically below what you'd pay the grid - for a set period, usually 10–25 years. At the end of the term, you may have the option to purchase the system, extend the agreement or have the equipment removed.

  • Commercial PPAs are typically suited to organisations with high daytime electricity consumption and suitable roof or land space - schools, warehouses, factories, offices, retail units and housing developments. Eligibility depends on energy usage, roof size and orientation, and creditworthiness. We carry out a no-obligation feasibility assessment to confirm suitability before progressing.

  • ECO4 (Energy Company Obligation 4) is a government scheme requiring large energy suppliers to fund energy efficiency improvements in eligible homes - primarily low-income or fuel-poor households. It covers measures including insulation, heat pumps and solar PV. ECO4 is expected to transition into the Warm Homes Plan from 2025 onwards. We can assess whether your project or housing stock qualifies and manage the process on your behalf.

  • The Boiler Upgrade Scheme (BUS) provides a government grant to homeowners replacing a gas or oil boiler with a heat pump. Currently, grants are available of up to £7,500 for air source heat pumps. The grant is paid directly to the MCS-accredited installer (like ourselves) and deducted from your installation cost. We handle the application as part of our standard installation process.

  • Yes. We manage the full process - eligibility checks, application submission, technical documentation and MCS sign-off. You don't need to appoint a separate funding consultant. Everything is handled in-house by the same team delivering your system.
