Government Decarbonisation Solutions
Supporting Tier 1 Contractors to Deliver Secure Retrofit and Decarbonisation
We specialise in delivering end-to-end retrofit and decarbonisation solutions across complex government and defence estate projects. Partnering with Tier 1 contractors, our team combines technical expertise, rapid mobilisation, and security-cleared experience to ensure projects are delivered safely, efficiently, and to the highest standards. From strategy and design through to installation, commissioning, and performance validation, we remove complexity and help our partners achieve measurable results on time and on budget.
Trusted Delivery Partner for Government Estate Retrofit
Retrofit programmes across government and defence estates go beyond standard delivery approaches. They demand:
- Strict compliance with UK retrofit standards
- Security-aware working practices
- Delivery within live operational environments
- Detailed audit trails and performance verification
- Integration with complex legacy building infrastructure
We provide specialist retrofit expertise that complements Tier 1 construction capability, ensuring projects are delivered right first time.

Fast Mobilisation When Programme Certainty Matters
Government and defence estate projects often operate to fixed funding windows and strict programme milestones. Delays at mobilisation stage can impact delivery confidence, commercial performance, and client relationships.
We are structured to mobilise rapidly and integrate seamlessly into Tier 1 project teams, enabling projects to move from award to delivery without unnecessary delay.
Our mobilisation approach includes:
- Pre-developed delivery processes
- Experienced teams ready to deploy into live programmes
- Rapid technical onboarding and project familiarisation
- Established supply chain relationships supporting immediate delivery
- Clear communication and reporting structures from day one
This allows Tier 1 contractors to maintain programme momentum and demonstrate early delivery confidence to their clients.
