Why choose HomeZero?

The UK has legislated to become “net zero” by 2050 which means a radical re-think about the way we heat our homes. The Government has committed to massively increasing the annual number of heat pumps fitted in our homes to 600,000 by 2028. Over 180 local councils have declared a climate emergency and intend to reach net zero before 2030. The ban of new diesel and petrol cars from 2035, is already driving the uptake of Electric Vehicles (EV). Urgent action is required to achieve these national goals.


Revised Building Regulations Part L for new build from June 2022 and further updates planned in 2025, will only address a small part of the housing challenge. Over 80% of the homes already built today will be in-use in 2050,  of which many are fitted with a combi boiler so lack the necessary indoor space to retrofit renewable heating.

Monodraught have developed HomeZero to assist Developers, Housing Providers and Contractors to reach Net Zero requirements. Providing a simple, single solution that can be quickly and easily fitted with minimal impact on the indoor amenity space of the home, HomeZERO brings all controls together, in a factory assembled energy module.
