With support at every stage of your journey
Whether you’re just starting to shape your Net Zero strategy or already delivering retrofit on the ground, our end-to-end solution offers a range of services delivered and shaped around your needs.
From early planning and funding solutions to delivery and ongoing energy services for your residents, we can take care of everything, for at least the next 25 years!!
Stage 1: Strategy
Have the right plan.
We can help you understand what’s possible across your whole housing portfolio, including homes you own now, plan to build, or plan to sell. Our strategy stage gives you a clear, high-level view of how and when you could reach Net Zero, what it might cost, and how much better off your residents could be. You’ll also see where savings can be made by aligning with planned maintenance, and where new income could come from shared savings or energy flexibility. It’s a strategic foundation to help you decide what to do next, and if you choose to move forward, we’ll help shape a practical, fundable delivery plan.
Stage 2: Project
Get confident in the outcomes.
In this stage, we help you turn strategy into action. We work with you to shape a viable, fundable retrofit project, identifying the homes to include, exploring the right upgrade measures, and building a clear plan for delivery.
We support you in finding the best way to fund the work, from available grants to innovative models like Energy-as-a-Service. If private finance is needed, we provide business case support, including financial modelling with scenarios and sensitivities.
Stage 3: Delivery
Get the job done right.
At this stage, our team of Retrofit experts take the lead to keep your project on track, fully compliant, and delivered to the highest standards. We oversee every part of the journey, from project management and PAS 2035 compliance to resident engagement, making sure each home gets the right measures and is installed properly.
Our resident engagement experts work with you to keep residents informed and supported throughout. It’s retrofit delivery you can trust, with expert guidance every step of the way.
Stage 4: Operate
A long term relationship with the home.
This is where your retrofit investment starts delivering long-term impact. Through our Energy Services, we help landlords power homes with greener, cheaper electricity, giving residents greater energy security and lower bills. Our team handles everything from billing and payment recovery to technology optimisation and monitoring. We provide a dedicated customer service team for residents, manage tariffs and portfolio billing through our energy bureau, and deliver ongoing performance insights.
Whether your energy upgrade was self-funded or privately financed, we help you maximise returns and keep your homes running efficiently, today and into the future.
