Energy Performance Certificate for
Commercial Buildings?
An Energy Performance Certificate rates the energy efficiency of a commercial building. It uses a grading system – A is the most efficient grade and G is the least efficient.
Your commercial building needs to have an Energy Performance Certificate if:
- you rent out or sell the premises
- a building under construction is finished
- there are changes to the number of parts used for separate occupation and the changes involve providing or extending fixed heating, air conditioning or mechanical ventilation systems.
You don’t need an Energy Performance Certificate if your commercial building is any of these:
- listed or officially protected and the minimum energy performance requirements would unacceptably alter it
- a temporary building only going to be used for 2 years or less
- used as a place of worship or for other religious activities
- an industrial site, workshop or non-residential agricultural building that doesn’t use much energy
- a detached building with a total floor space under 50 square metres
- due to be demolished by the seller or landlord and they have all the relevant planning and conservation consents.

What are the minimum requirements for an Energy Performance Certificate for commercial buildings?
From 1 April 2018, properties under new commercial leases needed an Energy Performance Certificate rating of at least ‘E’. From 1 April 2023, the minimum requirement will be applied retrospectively. It will be an offence to continue to let a property that does not reach the minimum standard of ‘E’ (unless it’s exempt). It is likely the minimum standards will become more strict over time as the UK works towards its target of net zero by 2050. At the moment, it seems the minimum standard for compliance will be band ‘B’ by 2030. Some estimates suggest that many commercial buildings will need to be upgraded to achieve this – one survey found that 80% of London’s office buildings are below band ‘B’.
How can you improve an Energy Performance Certificate for commercial buildings?
If you need to improve the Energy Performance Certificate rating of your commercial building, you might be wondering what you can do.
One of the most effective ways to upgrade your commercial building’s energy performance is to upgrade its window and door systems.
Here at Mercury Glazing we specialise in commercial aluminium windows and doors that help to reduce energy loss and enhance the thermal performance of commercial buildings. We work closely with you from start to finish to ensure you invest in a glazing solution that upgrades your building’s thermal performance and enhances its aesthetics.
The Alitherm 300 Aluminium Window is an energy-efficient and elegant window that works well in commercial buildings of all types. The Alitherm Heritage 47 Aluminium Window provides excellent energy efficiency without compromising on period aesthetics. The Aluminium Sliding Sash Window helps to preserve historic characteristics and style while upgrading thermal performance. We also supply a wide range of commercial doors suitable for all types of project from offices to shopfronts.
Adding value by upgrading the Energy Performance Certificate rating for commercial buildings
Clearly, there is a cost associated with investing in new window and door systems for your commercial building. However, the investment will reap rewards. Most importantly, it will help to make sure you are compliant with the new regulations so you can continue to let your commercial building. It will also enhance your commercial building’s value, which will affect how much rent you can charge or how much the building is worth when you want to sell it.

Enhanced Security and Performance
Beyond aesthetics and sustainability, aluminium commercial glazing prioritises safety and performance, providing peace of mind for building occupants and owners. Engineered to withstand extreme weather conditions and potential security threats, aluminium framing systems offer robust protection without compromising on design integrity. Moreover, advancements in glazing technology, such as laminated and tempered glass, provide enhanced security against intrusions and impacts while maintaining transparency and clarity. These features are especially crucial in commercial settings where safety and security are paramount concerns, ensuring that occupants can enjoy their surroundings with confidence.
Commercial Aluminium Windows:
Illuminating Spaces with Elegance
In the realm of commercial glazing, windows serve as the eyes of a building, allowing natural light to flood interiors and connecting occupants with the external environment. Commercial aluminium windows offer a perfect combination of elegance, functionality, and durability, enriching the architectural aesthetic while enhancing the indoor environment.
Aluminium windows are available in a variety of styles, including casement, sliding, tilt and turn, and pivot options, providing architects and developers with the flexibility to meet diverse design requirements and spatial constraints. With slim sightlines and sleek profiles, aluminium windows can help to , maximise views and enhancing the overall visual appeal of commercial buildings. Beyond aesthetics, commercial aluminium windows prioritise energy efficiency and thermal performance, featuring advanced glazing options and thermal breaks that minimise heat loss and reduce energy consumption. This not only creates a more comfortable indoor environment for occupants but also contributes to the overall sustainability of the building.
Moreover, aluminium windows are inherently durable and low-maintenance, with robust construction that withstands the rigors of commercial use and exposure to the elements. This ensures long-term performance and reliability, reducing the need for frequent repairs and replacements and lowering lifecycle costs for building owners. Furthermore, aluminium windows can be customised with a range of finishes, hardware options and glazing configurations to suit the unique design preferences and functional requirements of each project. Whether it’s a sleek office tower, a vibrant retail space, or a contemporary hospitality venue, aluminium windows offer architects and developers endless possibilities to create spaces that inspire, engage and endure.
