Sustainability Without Slowing Down: Sequenced Installations That Fit

As sustainability expectations rise across the UK housing sector, developers and principal contractors face a growing challenge: how to integrate renewables like solar PV and heat pumps into live construction programmes without causing delays, overruns, or compliance risk.

At Raven Renewables, we’ve supported dozens of new-build and retrofit projects where the difference between success and rework came down to one factor: how early and how seamlessly energy systems are integrated into the delivery model.

This blog outlines how you can meet net-zero targets without compromising on time, quality, or cost.

The Problem: Renewables as an Afterthought

In many housing projects, renewable energy systems are still treated as “add-ons” late in the design or construction process. This leads to:

• Schedule clashes: Technology install teams arrive out of sequence

• Rework: PV, heat pumps, or ventilation systems don’t align with built infrastructure

• Compliance risk: EPC or SAP targets fall short due to poor integration

• Cost escalation: Late design revisions or specialist re-engagements

The Solution: Raven’s Sequenced Delivery Model

At Raven Renewables, we take a different approach. With an in-house design team and direct delivery model, we ensure renewable integration happens on schedule, fully aligned with each project’s construction phase.

Here’s how it works:

1. Integrated In-House Design Support

Our internal design team works directly with project stakeholders to align solar PV, ASHPs, and ventilation systems with architectural intent, M&E layouts, and build sequencing.

2. Installation Milestone Planning

We build installation timelines into the overall construction programme—ensuring works proceed without clashes or delays.

3. Single-Partner Delivery

From system design and supply to on-site install and final commissioning, Raven delivers a seamless, end-to-end service with clear accountability.

4. Post-Install Performance Checks

We validate performance before handover—resolving install issues, ensuring system compliance, and supporting SAP/EPC confidence.

Case in Point: Solar PV Delivery Across 73 Camden Homes

In partnership with Camden Council, Raven Renewables recently delivered rooftop solar PV across 73 residential flats, supporting the borough’s decarbonisation goals and delivering real energy savings to residents.

With our in-house design and delivery team, we were able to:

• Design and specify solar systems to fit tight roof profiles and planning requirements

• Align installation with on-site contractor timelines and access constraints

• Manage DNO approvals and ensure MCS certification without delays

The outcome?

• On-time project completion

• Fully compliant system handover

• Operational savings for residents and emissions reductions for the council

This project is a strong example of Raven’s ability to manage low-carbon delivery in complex, occupied or constrained environments—without compromising timelines or compliance.
