Our Clients:
Retrofit isn't just replacing plant.
It’s about improving building performance. Many commercial buildings are facing increasing pressure from:
‣ Rising energy costs
‣ Ageing mechanical and electrical infrastructure
‣ Carbon reduction commitments
‣ EPC and MEES requirements
‣ Occupier & Tenant expectations
‣ Operations resilience
Our role is to help clients make informed investment decisions that improve building performance while minimising disruption to occupants and day-to-day operations.
Net Zero Statistics
The NHS has committed to net zero by 2040, with an interim target of an 80% reduction in emissions between 2028 and 2032.
For commercial buildings, Minimum Energy Efficiency Standards (MEES) require all leased properties to achieve an EPC rating of C by 2030 and B by 2035. Currently, most buildings are Rated E, those failing to meet the 2030 threshold will be unlettable
HVAC systems—responsible for up to 60% of energy use—offer the single largest opportunity to improve efficiency and reduce carbon emissions.
Upgrades such as replacing gas boilers, modernising air handling units and chillers, improving ventilation, and installing smart controls can reduce energy consumption by 20–40% and cut carbon emissions by up to 30%.
