Grants and funding
There are several government schemes available to help UK households with the cost of installing energy-saving measures and low-carbon heating.
Financial support can range from a few hundred pounds for insulation to over £7,500 for a new heating system. In some cases, low-income or vulnerable households may be eligible for the full cost of a whole-house retrofit.
