About Harmony Windows
Harmony Profiles Ltd is an Exeter-based architectural aluminium manufacturer specialising in high-quality windows, doors, bifolds, sliding doors, rooflights, and internal aluminium screens. With over 30 years of experience, they design, fabricate, and install bespoke aluminium glazing solutions for architects, developers, building companies, and self-build owners across the UK.
Their premises at Apple Lane in Exeter house the fabrication workshop, design and specification office, and showroom facilities. Aluminium fabrication involves a range of specialist machinery: cutting, pressing, powder coating, and assembly equipment, all served from the fixed electrical installation alongside standard office, lighting, and welfare circuits.
What they needed
Harmony Profiles required a full EICR across their Exeter premises, covering 69 circuits. For a manufacturing business operating bespoke fabrication equipment, the electrical installation carries a diverse load profile with both single and three-phase circuits serving machinery and production processes alongside standard commercial circuits.
As an established Exeter business with over 30 years of trading, maintaining a current EICR is part of their ongoing compliance obligations under the Electricity at Work Regulations 1989 and their insurance requirements. The report needed to cover the full site and produce a NICEIC-certified certificate to BS 7671 18th Edition standards.
What the inspection involved
Andy Bradbury from M&E Contrax carried out the inspection at the Apple Lane premises. For a fabrication facility, the inspection needed to assess both the standard commercial circuits and the specialist circuits serving manufacturing equipment. The inspection covered all distribution boards and sub-boards, all circuits serving production and fabrication areas, and all office, welfare, and external circuits on the site.
What the inspection covered
| Services Provided | |
|---|---|
| Full visual inspection of 198 circuits | Warehouse and distribution area electrical assessment |
| Main intake and primary distribution board assessment | Office and welfare area circuit testing |
| Insulation resistance and continuity testing | Review of circuit protection against BS 7671 18th Edition |
| Earth fault loop impedance testing | Assessment of labelling and circuit identification |
| RCD and RCBO protective device testing | Full NICEIC EICR certificate and report on completion |
What we found
The installation at Harmony Profiles’ Exeter premises was assessed across all 69 circuits. The site has the characteristics typical of a well-established small to medium manufacturing facility that has evolved over time: a core installation with additional circuits added as the fabrication operation has grown and machinery has been updated.
The inspection identified the condition of all circuits and produced a clear classification of all findings. In fabrication environments, circuits serving CNC cutting machinery, powder coating equipment, and assembly tools are subject to higher electrical stress than standard commercial circuits, and the inspection pays particular attention to protective device condition, conductor insulation integrity, and the earthing of machine frames and metalwork.
The EICR report gave Harmony Profiles a circuit-by-circuit record of their installation, with all findings classified to BS 7671 standards and clear recommendations where improvements were identified.
The result
On completion, Harmony Profiles received their full 69-circuit EICR report and NICEIC certificate. The report gives the business the compliance documentation required under the Electricity at Work Regulations and for their insurers, and provides a clear baseline record of the Exeter premises electrical installation.
For a business with specialist fabrication equipment where electrical reliability is directly linked to production continuity, the EICR also serves as a practical maintenance tool: identifying any areas of the installation where proactive attention before the next inspection cycle will prevent operational disruption.
Electrician’s Notes
Fabrication facilities have a different set of electrical considerations from standard commercial offices or retail premises. The machinery circuits at Harmony Profiles carry three-phase loads and the earthing of machine frames and metalwork needs to be assessed carefully. The Apple Lane site was well-organised and the fabrication team were accommodating in terms of scheduling around their production workflow. The 69-circuit scope is manageable in a single well-planned inspection day, and we were able to complete the full report without any disruption to their fabrication operation. Harmony Profiles have a well-maintained facility and the inspection reflected the care they take with their premises.
