Retrofit Energy Planning

Unlock Net-Zero Potential in London’s Existing Buildings with Ground Source Heat Pump Solutions

 London is home to thousands of ageing buildings with EPC ratings of D or lower—many of which are ripe for transformation. At London Geothermal Ltd, we specialise in turning these properties into net-zero, EPC-A rated assets using deep retrofit strategies centred around ground source heat pumps (GSHPs). Whether you’re a private landlord, a real estate investor, or managing a large housing estate, our tailored retrofit plans can significantly increase asset value, reduce emissions, and unlock new revenue via carbon credits.  


At London Geothermal Ltd, we specialise in comprehensive energy retrofit strategies for:


  • Buy-to-Renovate investors looking to upgrade EPC ratings to A and resell at premium value
  • Estate developers and site managers planning whole-building or multi-unit retrofit transformations
  • Property agents navigating Boiler Upgrade Schemes, ECO4 and Home Upgrade Grants
  • Social housing and councils aiming for compliance with MEES and zero-carbon targets

What We Offer

Carbon Credit Revenue Potential

Why Retrofit with GSHP?

 

  • End-to-End Energy Planning: From site audits and thermal imaging to energy modelling, we craft the optimal retrofit roadmap.
  • Bespoke Technology Integration: Whether it’s a GSHP, ASHP, hybrid system or solar + battery combo—we match tech to building type.
  • EPC-to-Net Zero Execution: We design solutions to lift buildings from EPC E/F to A or B ratings—ready for resale or long-term rental.
  • Funding Navigation: We secure and manage grant applications such as:
    • Boiler Upgrade Scheme (£7,500)
    • ECO4 funding
    • GHG-LAD schemes
    • Social Housing Decarbonisation Fund
  • Carbon Impact Modelling & Reporting: Ideal for ESG investors, REITs or green mortgage lenders.
     

Why Retrofit with GSHP?

Carbon Credit Revenue Potential

Why Retrofit with GSHP?

  • Boiler Upgrade Incentives: Eligible homes can benefit from the Boiler Upgrade Scheme (BUS) and other government-backed grants, significantly lowering capital costs.
  • Low-Carbon + Low-Operating Cost: GSHPs offer superior long-term savings compared to gas boilers and air-source heat pumps—especially in urban areas with limited roof space.
  • Year-Round Efficiency: Our GSHP systems are designed for both heating and cooling, ensuring optimal COP performance based on outdoor conditions via smart control systems.
  • Grid Flexibility: Decentralised heat supply can support local 5th-gen networks or standalone heat zones.

Carbon Credit Revenue Potential

Each kWh of fossil fuel replaced by GSHPs contributes to verified CO₂e savings. We help our clients:

  • Quantify carbon reductions
  • Connect with accredited carbon credit buyers
  • Set up ongoing revenue streams for multi-unit projects
     

This opens the door to payback models under 10 years and green finance opportunities.
