Decarbonisation consulting grounded in real delivery

Decarbonisation is no longer a future ambition. For many organisations, it is an immediate operational requirement. Heliaxis provides structured decarbonisation consulting designed to bridge the gap between strategy and delivery — with advice grounded in practical experience.

Housing Associations
Managing diverse housing stock and balancing decarbonisation with tenant needs and funding constraints.
Local Authorities
Responsible for public buildings and estates with net-zero commitments and value-for-money requirements.
Public Sector Bodies
Delivering net-zero commitments while maintaining compliance and transparency in spending decisions.
Education Providers
Managing campuses and mixed-use estates with varied building types and usage patterns.
Commercial Portfolios
Multi-site organisations planning long-term energy and sustainability upgrades across their estate.
Asset Managers
Estates teams planning long-term upgrades and requiring structured, implementable programmes.

Why decarbonisation requires structured planning

Decarbonisation is not a single technology decision. It is a multi-year process involving sequencing, prioritisation and coordination across multiple systems.

Heliaxis helps organisations navigate the balance between moving too quickly and moving too slowly — providing structured, phased advice that supports informed decision-making.

Risks of moving too quickly:

  • •Technologies poorly matched to buildings
  • •Electrical or capacity constraints
  • •Missing funding opportunities
  • •Disappointing cost or carbon reductions

Risks of moving too slowly:

  • •Rising energy costs
  • •Asset obsolescence
  • •Increasing regulatory pressure
  • •Lost funding windows

Our decarbonisation consulting methodology

Heliaxis follows a structured methodology designed to move organisations from uncertainty to action.

Team collaboration on decarbonisation strategy
1
Discovery & Data Capture
Understanding the estate, objectives and constraints through asset data review, energy consumption analysis and stakeholder discussions.
2
Options Appraisal
Assessing interventions including solar PV, battery storage, electrical upgrades, heating options and lighting efficiency improvements.
3
Prioritisation & Phasing
Prioritising actions based on impact, risk and funding alignment, developing phased delivery plans that are achievable.
4
Funding Alignment
Supporting alignment with Local Authority programmes, Shared Prosperity Fund initiatives, public sector capital and private finance options.
5
Procurement-Ready Outputs
Technical scopes, specifications and options narratives suitable for decision-makers and procurement processes.
6
Delivery Support
Unlike purely advisory consultancies, Heliaxis can support delivery, ensuring that recommendations translate into real outcomes.
Housing Associations

Decarbonising housing stock at scale

Housing associations face some of the most complex decarbonisation challenges. Housing stock often spans multiple decades, construction types and energy performance levels. Tenant needs, safety considerations and affordability must be balanced alongside carbon reduction targets.

Heliaxis supports housing associations with a practical, delivery-led approach to stock decarbonisation.

Assess current stock performance and constraints
Identify property archetypes and priority interventions
Evaluate technology options
Develop phased retrofit plans aligned to budgets
Support procurement-ready scopes and delivery

Key challenges we address:

Mixed Stock

Mixed-age and mixed-construction housing stock

Varying Performance

Varying EPC ratings and thermal performance

Limited Capacity

Limited electrical capacity in older properties

Tenant Considerations

Tenant disruption and engagement concerns

Technology-neutral, outcome-focused advice

A key principle of our advisory work is neutrality. While we have deep experience delivering solar, battery, heating and electrical projects, our consulting work is focused on outcomes, not selling a particular technology.

Where Technologies Work

Transparent about where technologies perform well and deliver genuine value.

Where Constraints Exist

Honest about limitations and constraints that may affect outcomes.

Alternative Approaches

Clear guidance where alternative approaches may be more appropriate.

Typical outputs from a Heliaxis engagement

All outputs are designed to support decision-making and next steps. Depending on scope, deliverables may include:

Estate or stock-level assessment summaries
Technology options matrices
Phased decarbonisation roadmaps
Cost and carbon impact narratives
Funding-aligned project scopes
Implementation-ready recommendations

Why choose Heliaxis for advisory work?

Clients choose Heliaxis because our advice is grounded in delivery experience. We understand what can realistically be implemented and what risks to avoid.

Practical, non-academic approach
Experience across residential, commercial and public sector
Clear communication for senior decision-makers
