ABOUT GreenCore Research

At Greencore Research, we help UK businesses and public sector organizations transition away from outdated, oil-based energy systems towards cleaner, more cost-effective, and sustainable alternatives.

We start with free digital audits that analyze your fuel usage, supply contracts, and infrastructure. Using this data, we identify better solutions whether it's switching to lower-cost fuel suppliers, exploring alternative fuels like HVO or B100 biodiesel, or unlocking access to government-funded upgrades.

​

Our aim is simple:

 

  • Save you money through smarter contracts and supplier routes

 

  •  Make you greener by reducing reliance on fossil fuels

​

  • Close the loop by supporting the creation of a circular energy and tech economy

​

Whether you're a school, care home, agricultural business, manufacturer, or rural institution we help you make informed, financially smart, and environmentally responsible decisions.

Our work supports national goals for decarbonization while putting real savings and long-term resilience into the hands of the organizations that need it most.

WHY WE DO WHAT WE DO

At Greencore Research, we believe that every organisation deserves fair, transparent, and sustainable energy solutions.

The shift to greener energy isn’t just about reducing emissions it’s about building resilience, unlocking funding, and future-proofing operations. Whether it’s public institutions like schools and care homes, or private industries like farming and food production, the pressure is growing to lower carbon footprints and adopt cleaner technologies. We exist to make that shift easier, faster, and more cost-effective.

The fuel oil market is largely unregulated, meaning prices can vary significantly between suppliers even for the same product and delivery location. Once an organisation commits to a supplier and stops monitoring the market, prices often increase quietly over time. It’s common for organisations to overpay by thousands simply due to outdated contracts or passive renewals.

We break this cycle by auditing your current pricing and suppliers, benchmarking your costs against the wider market, negotiating fair and competitive fuel contracts with trusted partners, and offering alternative fuel options such as HVO or B100 that support both cost savings and environmental goals.

Our mission is to put you back in control of your energy supply saving you money now, and helping you move confidently toward a cleaner, more sustainable future.

 Boiler Ban Timetable: The Transition Away from Oil Heating
The UK Government has confirmed a national phase-out of new fossil fuel heating systems for properties that are off the gas grid, including those currently using oil, LPG, or coal.

Key Dates
  • From 2026: new fossil fuel boilers cannot be installed in domestic off-grid buildings (homes).
  • From 2028: the same rule will apply to non-domestic buildings  including schools, care homes, estates, and commercial sites.
Once an existing oil or LPG boiler reaches the end of its life, it cannot legally be replaced with another fossil fuel system.
This policy forms part of the UK’s Heat and Buildings Strategy and is underpinned by the Energy Act 2023 and guidance from the Department for Energy Security and Net Zero (DESNZ).
In practice, this doesn’t mean that every oil boiler must be removed overnight  but it does mean that continuing on oil heating will become increasingly unviable.
Fuel prices, servicing availability, and compliance standards will all tighten, making it essential for organisations to plan their clean-heat transition early.
