What the Warm Homes Plan Means for Delivery at Scale

The UK government’s Warm Homes Plan marks a major shift in how home energy upgrades will be delivered across the country. With £15bn committed and clear targets for low-carbon technologies, the emphasis has moved from policy ambition to delivery at scale.

According to Alastair Murray, CEO and Founder of Rendesco, the importance of the plan lies not just in the size of the investment, but in the way government is aligning funding, regulation and delivery models around long-term, integrated programmes.

Scale That Matches the Challenge

UK Government Launches the Warm Homes Plan: £15bn Investment to Upgrade Britain’s Homes and lift up to one million families out of fuel poverty. Alastair Murray sees this as a meaningful step change for the sector, creating the scale required to move beyond fragmented schemes and pilot projects.

This level of commitment provides greater certainty for organisations delivering low-carbon infrastructure, enabling sustained investment in systems, skills and supply chains.

Heat Pumps Move Into the Mainstream

Heat pumps sit at the centre of the plan, with government targeting more than 450,000 installations per year by 2030. Alastair notes that this signals a clear intention for heat pumps to become a mainstream replacement for traditional heating systems.

The focus now shifts to delivering these upgrades efficiently and reliably, with standardised processes that minimise disruption for households and allow deployment at pace.

Integrated Energy Systems, Not Single Technologies

Alongside clean heating, the Warm Homes Plan places strong emphasis on solar energy, with rooftop panels expected on up to three million additional homes. Combined with support for batteries, smart controls and flexible energy use, the plan reflects a system-wide approach to home electrification.

Alastair highlights that this integrated model - bringing together generation, heating, storage and control - is critical to delivering tangible energy savings and long-term performance, rather than treating each technology in isolation.

Finance Moves From Barrier to Enabler

A significant feature of the Warm Homes Plan is its approach to finance. In addition to grants, it introduces a broader mix of funding tools, including the extension of the Boiler Upgrade Scheme, the Warm Homes Fund and low- or zero-interest consumer loans.

From Alastair’s perspective, this represents a practical shift. By addressing upfront cost more directly, the plan helps remove one of the biggest barriers to adoption and supports faster, more consistent delivery.

Programme Delivery for Low-Income Homes

The plan also signals a move towards programme-based delivery for low-income households, with more than £5bn committed by 2030 and an intention to bring schemes together into a single integrated programme from 2027/28.

Alastair sees this as a more effective way to deliver outcomes at scale, allowing upgrades to be coordinated across streets and neighbourhoods rather than delivered on a piecemeal basis.

Clear Direction for New Build, PRS and Heat Networks

The Warm Homes Plan provides clearer signals across different parts of the housing market:

• New build regulations under the Future Homes and Buildings Standard are expected in early 2026, embedding low-carbon heating as standard.

• The private rented sector is set on a deadline-driven pathway, with EPC C required by October 2030.

• Heat networks are given a longer-term runway through zoning, regulation and funding aligned into the next decade.

Alastair notes that this clarity is essential for unlocking investment and enabling delivery partners to plan with confidence.

Quality, Skills and Supply Chain Investment

Alongside deployment targets, the plan places greater emphasis on quality, consumer protection and workforce development. Measures include tighter oversight of certification, investment in training and funding to support UK manufacturing.

From Rendesco’s perspective, this should favour delivery models that prioritise performance, accountability and long-term operation, rather than short-term installations.

A Plan Designed for Scaled Delivery

Taken together, the Warm Homes Plan positions home electrification as national infrastructure. As Alastair Murray sees it, success will depend on the ability to deliver upgrades at scale, efficiently and reliably, while demonstrating real and lasting energy savings for households.

For organisations already operating integrated, energy-as-a-service models, the plan reinforces the direction of travel and creates a strong platform for long-term delivery.

How Rendesco Supports Delivery Under the Warm Homes Plan

The Warm Homes Plan focuses on delivering low-carbon energy at scale, with systems that work well over the long term. To do this, solutions need to be simple to install, easy to manage and reliable for households.

Rendesco supports this through Rendesco Flow, which brings together low-carbon heating, on-site energy generation, storage and smart controls into one managed system.

For homeowners, Rendesco Flow makes low-carbon heating straightforward. The system automatically uses energy at cheaper times, helping keep bills lower and more predictable, while providing quiet, consistent heating and hot water all year round.

Flow also supports a cleaner, lower-carbon home. Heat pumps are much more efficient than traditional heating systems, reducing emissions while improving comfort. Installation is quick and low-disruption, and ongoing monitoring through RendescoCare helps ensure the system continues to run smoothly over time.
