Hometree is tackling one of Europe’s biggest climate and cost-of-living challenges: inefficient, fossil-fuel-based home energy systems in a building stock that will largely still be standing in 2050. With 75% of buildings energy-inefficient and 35% still heated by fossil fuels, decarbonizing existing homes is critical.
Hometree’s platform acts as a one-stop shop for homeowners, bundling installation, financing, service, monitoring, repair and insurance for low-carbon energy systems. Its Home Cover product reduces the friction of adopting expensive but efficient equipment by wrapping repairs and replacements into an accessible insurance-like offering. The acquisition of BeWarm further strengthens this proposition by adding green home loans and heat lease plans, making upgrades like heat pumps and other clean technologies more affordable.
A key differentiator is Hometree’s go-to-market strategy. Instead of leading with high-ticket hardware, Hometree acquires customers through home cover insurance, achieving low customer acquisition costs and strong margins. This ‘trojan horse’ approach gives Hometree thousands of direct homeowner relationships, which it can then leverage to cross-sell decarbonization hardware such as heat pumps (with potential energy savings of up to 50%), and over time PV, EV chargers and home batteries. This positions Hometree as a digital challenger to incumbents like Homeserve and British Gas, with a scalable, data-rich platform model.
The investment thesis is reinforced by a seasoned leadership team. Founder and CEO Simon Phelan brings deep private equity and operational experience, having led a >£330m turnover business as CEO at Better Capital’s largest investment. He is supported by CFO David MacLean, who is building out the financing stack drawing on his FinTech background, and commercial leaders CCO Pranjal Arya and CBO Mark Whitbread, who are driving UK growth and European expansion.
Hometree has raised $46M in a Series B round led by 2150 and Energy Impact Partners, with participation from Legal & General Capital and AENU, and continued support from existing investors Inven Capital, FJ Labs and Oxford Capital. This capital, combined with the BeWarm acquisition, positions Hometree to consolidate its UK leadership and scale into Europe as a leading residential energy efficiency and home decarbonization platform.
Hometree is building a one-stop residential decarbonization platform at exactly the part of the problem where impact and adoption are currently most constrained: existing homes.
On the problem side, housing is a major driver of emissions and energy waste, with most European buildings energy-inefficient, a large share still heated by fossil fuels, and the vast majority of today’s stock expected to still be in use by 2050. This makes retrofitting and upgrading existing homes—rather than just focusing on new builds—central to any credible decarbonization pathway.
Hometree addresses this by combining installation, financing, service, monitoring, repair and insurance into a single, integrated offering. Instead of homeowners having to navigate fragmented providers and high upfront costs, Hometree’s platform bundles:
- Home Cover insurance to de-risk expensive repairs and replacements and build a trusted, recurring relationship.
- Low-carbon hardware such as heat pumps (with potential energy savings of up to ~50%), and over time PV, EV chargers and batteries.
- Financing solutions via the acquisition of BeWarm, enabling green home loans and heat lease plans that remove upfront cost barriers.
The go-to-market strategy is particularly compelling. By leading with home cover insurance as a high-margin, low-CAC entry product, Hometree acquires and owns thousands of customer relationships at scale. This creates a powerful cross-sell engine for higher-ticket decarbonization upgrades over time, in contrast to competitors that struggle with high acquisition costs and thin margins when trying to sell hardware directly. It positions Hometree as a digital challenger to incumbents like Homeserve and British Gas, with a data-rich, platform-based model rather than a purely transactional one.
The team further underpins the thesis. Founder & CEO Simon Phelan brings deep private equity and operational experience, including leadership of a large-scale business with >£330m turnover. He is complemented by a leadership bench with directly relevant expertise: CFO David MacLean on fintech and financing products, CCO Pranjal Arya and CBO Mark Whitbread on scaling commercial and operational execution across the UK and, ultimately, Europe.
The $46M Series B led by 2150 and Energy Impact Partners, alongside strategic investors such as Legal & General Capital and AENU and continued support from existing backers, provides the capital to consolidate Hometree’s UK position and expand into a pan-European residential energy efficiency platform. In combination, the scale of the problem, the integrated product and financing stack, the efficient customer acquisition strategy, and the strength of the team create a strong foundation for both climate impact and commercial success.
