Cucumber Eco Solutions: EPC and energy efficiency consultancy for landlords

Cucumber Eco Solutions is a British consultancy specialising in Energy Performance Certificates (EPCs) and improving the energy performance of rental and privately owned homes. The company presents itself as a partner that starts with the property evidence — the current certificate and measured data — before recommending any investment. Its approach is to review the existing EPC, check the available documentation and, only when it will provide useful information, carry out specific tests such as air tightness or thermal transmittance (U-value) testing. From there, it proposes a proportionate roadmap and coordinates the work with accredited installers.

Services for landlords and homeowners

The firm serves both landlords with a single property or entire portfolios and homeowners preparing to sell or looking to reduce bills. Its offer covers:

• EPC advice and planning for landlords, with a review of the certificate, the score and the missing evidence.
• Specialist EPC testing: air tightness and U-value testing to replace assumptions with measured data.
• MEES (Minimum Energy Efficiency Standards) planning and compliance with minimum energy efficiency standards.
• Application and advice on the Boiler Upgrade Scheme (BUS), a grant for heat pumps in England and Wales.
• Coordination of heat pump installations, low-carbon heating and infrared heating.
• Advice on insulation, solar PV and battery storage.
• Whole-home energy plans aimed at reducing bills without guesswork.
• Finance options for customer-funded measures, subject to approval.

Methodology: evidence before expenditure

The working process is structured in four steps. First, the current EPC, the score and the available evidence are reviewed. Then the documentation is checked and, if appropriate, air tightness or U-value testing is carried out. Third, the proportionate improvement route, available grants and the right timing are compared, keeping current minimum standards separate from future policy. Finally, the work is coordinated with a written scope detailing what is included, who delivers it and when payment is due. The company stresses that it does not promise a specific saving on bills from improving the EPC and that the D-to-C route is one option, not the limit of its service.

Regulatory deadlines and public grants

The consultancy works with the confirmed regulatory horizon: privately rented homes in England and Wales must reach EPC C by 1 October 2030. The company notes that 2027 will change the measurement methodology and that the future EPC will place more emphasis on the building fabric, heating systems and smart readiness, while there is currently no universal rule requiring solar or renewable heating in every home to reach C. On funding, the Warm Homes: Local Grant is channelled through participating local authorities for low-income households in privately owned homes with EPC D to G, and includes measures such as insulation, solar and air source heat pumps. The Boiler Upgrade Scheme offers upfront support for eligible heat pump installations in England and Wales. The Warm Homes Plan envisages improvement packages for low-income households and low or zero interest financing, with details varying by programme and location.
