Quality installations

A modern, professionally installed consumer unit

Whether your existing fuse board is outdated, you're refurbishing a property, or you need additional protection and capacity assessed, we can inspect your installation and recommend suitable options.

Every replacement is planned around the condition of the existing circuits. Inspection, testing, certification and applicable Building Regulations notification form part of the work.

Important: An upgrade isn't automatically required simply because a consumer unit is older. We assess the installation and explain what is appropriate before quoting.
