Popular questions
What is retrofitting?
Retrofitting means upgrading existing buildings with modern systems and materials to improve energy efficiency, safety, and performance — without the need for full reconstruction.
How is retrofitting different from renovation?
Renovation focuses on aesthetics and layout, while retrofitting focuses on improving a building’s functionality, such as insulation, heating, ventilation, and compliance with current safety and energy standards.
What are the main benefits of retrofitting?
Retrofitting reduces energy bills, improves comfort, enhances fire safety, increases property value, and helps meet UK carbon reduction goals.
Can any building be retrofitted?
Most buildings can be retrofitted, whether residential, commercial, or public. Our experts carry out detailed assessments to determine the best solutions for your property type and age.
Can retrofitting help me achieve better EPC ratings?
Absolutely. Energy-efficient upgrades such as improved insulation, glazing, and modern heating systems can significantly improve your building’s Energy Performance Certificate (EPC) rating.
How long does a retrofitting project take?
The duration depends on the size and scope of the project — small upgrades can take a few weeks, while full building retrofits may take several months. We always provide a clear timeline before work begins.
