Connected for Warmth logo

The Connected for Warmth Scheme is a government scheme that is designed to help people who are at risk of fuel poverty, or are vulnerable, to heat their homes. It also has the objective of reducing carbon emissions.

Under the Connected for Warmth scheme, qualifying households receive a free air source heat pump system, which is fully installed in their home. This includes the heat pump itself (which is located outside) plus a new water cylinder, radiators, all the necessary pipework, valves and heating controls.

Qualification for the scheme depends on meeting two key criteria:

  1. The property – homes must have sufficient insulation and either electric heating or no heating installed.
  2. Household income – the level of net household income (after tax) must be less than £31,000 or someone in the household must receive certain benefits.

If your home doesn’t have sufficient insulation, then we may be able to install this for you – also for free – under a government scheme.

Connected for Warmth is funded by UK energy companies under their obligations as set out by the government under the ECO4 scheme. (ECO stands for Energy Company Obligations.)
