Decarbonisation FAQS

What does decarbonisation mean for buildings?

Decarbonisation for buildings describes the process of reducing carbon emissions throughout a property’s lifecycle. This encompasses energy-efficient design principles, renewable energy integration and the use of sustainable materials.

Energy efficiency measures—including heating system electrification, replacing traditional gas boilers with heat pumps, and incorporating advanced smart technologies—work together to lower energy consumption and greenhouse gas emissions. As part of the Axis CLC Group, Concept helps clients achieve their Net Zero 2050 targets through these proven solutions.

What are decarbonisation and retrofit services?

Decarbonisation and retrofit services involve upgrading existing properties to enhance energy efficiency, sustainability and environmental performance, ultimately reducing carbon emissions.

Common improvements include insulation upgrades, double-glazing installations, solar PV systems and modern heating system replacements.

Concept’s decarbonisation and retrofit services strengthen environmental performance, supporting clients in meeting Net Zero targets whilst delivering measurable improvements in energy efficiency and occupant comfort.

What energy efficiency measures (EEM) does Concept install?

Concept provides a comprehensive range of Energy Efficiency Measures:

  • Air Source Heat Pumps (ASHPs)
  • District Heat Networks (DHN)
  • Electric Heating Systems
  • Electric Vehicle (EV) Charging Point Installations
  • Energy-Efficient Windows and Doors
  • Insulation Solutions:
    External Wall Insulation (EWI)
    Re-Cladding Solutions
    Loft Insulation
    Cavity Wall Insulation
    Internal Wall Insulation
  • Solar PV Panel Systems
  • Mechanical Ventilation with Heat Recovery (MVHR) Systems

How can property retrofitting support landlords’ Net Zero commitments?

Retrofitting existing properties significantly improves energy efficiency and reduces carbon emissions, directly supporting the UK Government’s Net Zero strategy and landlords’ environmental obligations.

By implementing energy-efficient measures such as enhanced insulation, solar panel installations and low-carbon heating systems, landlords can substantially reduce energy consumption, improve EPC ratings, and meet increasingly stringent environmental standards. Concept works with landlords and housing providers to develop tailored retrofit strategies that balance regulatory compliance, cost-effectiveness and resident comfort, creating a pathway to Net Zero that’s both practical and sustainable.
