Heat Load Calculator
About the Heat Load Calculator
The Head Load Calculator is an online tool to help MCS certified low-carbon heating installers complete a BS EN 12831-1: 2017 compliant heat load calculation, as required in the Heat Pump Design Standard (MIS 3005-D) and the Biomass Installation Standard (MIS 3004).
Installers will be able to calculate room by room heat load calculations of a property, which is crucial for ensuring a heat pump or biomass system is sized correctly and meets the requirements of MCS standards.
The Heat Load Calculator is exclusively available for MCS certified installers and those who are in the process of gaining certification. The existing Excel-based tool remains available on the MCS website but will no longer be supported or updated.
Below you will find information about the Heat Load Calculator including how it works and the ability to provide your feedback to contribute to updates in the future.
HOW THE HEAT LOAD CALCULATOR WORKS
Equipped with guidance prompts, pop-ups, and real-time support, the new online tool will streamline the process for installers. This will help to reduce errors and improve efficiency, giving installers more time to focus on delivering high-quality low-carbon heating installations for their customers.
The Heat Load Calculator calculates the heat requirements of domestic properties through factors such as building specification, room dimensions and design temperatures.
Once calculations are complete, the tool generates a comprehensive report that can be saved directly on the platform or downloaded for use in quotations, audits and compliance checks. Every MCS certified low-carbon heating installer will have their own account and will be able to share calculations seamlessly across their business.
There is a user guide to help you get to grips with the new Heat Load Calculator. You can view this using the button below.
If you are a certified installer with an MCS Installer Database (MID) login, then you will automatically be registered for the tool. Launch the MCS Heat Load Calculator and follow the steps to create your account.
If your email is not recognised by the tool but you are MCS certified, contact the MCS Customer Support Helpdesk on 0333 103 8130 or email: hello@mcscertified.com. Alternatively, you can submit an enquiry/call-back request here.
If you are in the process of obtaining MCS certification, you will be able to request temporary access to the tool from January.
WHAT’S HAPPENING TO THE OLD EXCEL TOOL?
While the Excel tool has served its purpose, it has its limitations and has become outdated. It is still available to download here for those who want to use it, but it’s important to understand that it is no longer supported or updated by MCS.

The new tool generates a final report that can be saved on the platform itself, as well as an option to download/export to your device. This allows installers to pull up specific heat load
calculations when being audited or assessed.
