7 Mistakes You’re Making with Your Consumer Unit (and How Electricians in Dorset Can Fix Them)

Dorset Electrical Solutions is currently conducting consumer unit upgrades throughout Bournemouth and Poole to bring residential and commercial properties into compliance with BS 7671 (18th Edition). Our team of City & Guilds qualified electricians frequently identifies critical installation errors that compromise safety and violate current UK wiring regulations. A primary mistake observed in older Dorset properties is the continued reliance on combustible plastic enclosures. Current standards mandate non-combustible metal units for all domestic installations to contain potential electrical fires. Our technicians replace these outdated units with modern, fully-compliant distribution boards that meet all national safety criteria.

Technical oversights often involve incorrect mounting heights and inadequate circuit protection. We frequently find consumer units in Ringwood and Ferndown mounted outside the Part M regulatory range of 1350mm to 1450mm, which limits accessibility for isolation in emergencies. Many installations also lack Surge Protection Devices (SPD) and Arc Fault Detection Devices (AFDD), leaving sensitive electronics vulnerable to voltage spikes. Furthermore, ingress protection (IP) is often breached by leaving unused ways open or failing to use fire-rated grommets at cable entry points. Our team performs comprehensive pre-work testing to identify existing faults before any hardware is upgraded, ensuring the new system operates without nuisance tripping.

Our service portfolio extends to specialized property maintenance, including the installation of positive input ventilation (PIV) systems. These units are deployed to combat mould, damp, and condensation in coastal properties across the region. We ensure electrical safety in Poole by providing detailed Electrical Installation Certificates (EIC) for all work, providing documentation for insurance and building control compliance. Our electricians in Dorset are available for 24/7 emergency call-outs to address hardware failures and distribution board faults in commercial and industrial settings.

With over 20 years of experience, Dorset Electrical Solutions maintains a 98% customer satisfaction rate by delivering cost-effective and reliable electrical designs. We are currently managing complex rewires and security system installations for several commercial clients in the Dorset area.
