Domestic or micro CHP systems can be installed in place of standard domestic boilers and so there are few design and planning issues. However, it is worth contact the local council building control officer to ensure compliance with new Building Regulations.

• Connection issues

A number of regulatory aspects affecting micro-CHP were not designed with micro-CHP in mind. These include issues such as the right to interconnect micro-CHP with the distribution network; metering requirements for micro-CHP; and valuing micro-CHP generated electricity that is exported to the grid. The current situation is not preventing the installation of micro-CHP units, but could present problems for the existing grid if large numbers of 1 kW units are installed in households.
