Your responsibilities as a homeowner
Did you know that it is your responsibility to ensure that any electrical installation in your home complies with building regulations?

Small detached buildings are exempt from building regulations

Adding a porch to provide shelter at the entrance of your home is often a smaller project which doesn't require building regulations approval provided that:
- The porch is at ground level
- The porch is less than 30 square metres in floor area
- The existing front entrance door of the house around which the porch is built must stay where it is
- The porch mustn't adversely affect access if there are ramps or other features for disabled people already in place
Windows and electrics
If you're planning a more complex porch build which will include windows and/or electrical installations, these will need to meet the standards set in the relevant parts of the Building Regulations.
