Did you know that you can get paid by the Government to install heat pump technology in your home? As part of the UK commitment to global climate change targets, the domestic RHI has been introduced to promote the adoption of ground source heat pumps and air source heat pumps.

The Domestic RHI is aimed at private residential self-build and custom build, as well as all retrofit applications

Commercial Applications

Payments over 20 Years

Index Linked

Tariff Guarantee


The Non-Domestic Renewable Heat Incentive (RHI) is a government environmental programme that provides financial incentives to increase the uptake of renewable heat by businesses, the public sector and non-profit organisations.

Eligible installations receive quarterly payments over 20 years based on the amount of heat generated. The scheme covers England, Scotland, and Wales. 



building regulations


It is established fact that energy efficient homes attract higher property prices. However, at Alto Energy we understand that achieving building regulations and improving the thermal performance of each property can be a difficult path to navigate.

Heat pumps and underfloor heating save carbon dioxide emissions compared with conventional fossil fuel technologies and radiator distribution. These carbon savings contribute to towards your compliance with Part L of the Building Regulations.
