GBL Electrical & Plastering provides professional commercial electrical services in Belfast for businesses, property owners and commercial premises. From electrical improvements and lighting upgrades to testing and installations as part of larger refurbishments, our family-run team provides a dependable service tailored to the needs of each property.
Commercial properties require electrical systems that support the day-to-day needs of the people and businesses using them. GBL provides commercial electrical installations, EICRs and electrical testing, and commercial lighting and electrical upgrades for existing premises and properties undergoing refurbishment.
We carry out commercial electrical installations in Belfast for existing premises, alterations and refurbishment projects. Electrical work can be planned around changes to the property, helping ensure sockets, lighting and other electrical points are positioned to suit the finished commercial space.
GBL provides Electrical Installation Condition Reports (EICRs) and electrical inspections for commercial installations. We can assess the condition of existing electrics and identify areas requiring attention, helping property owners and businesses better understand the condition of their electrical installation.
We undertake commercial lighting and electrical upgrades for businesses looking to improve or modernise existing premises. Our previous commercial work includes replacing faulty LED batten fittings, alongside lighting replacements and other electrical improvements.
Every commercial project has different electrical requirements, particularly when an existing property is being altered or refurbished. We can carry out electrical work alongside the wider project, from replacing individual fittings to completing more extensive installations and upgrades.
GBL also offers professional plastering alongside our electrical services. For commercial refurbishments requiring both trades, this gives customers the option of using the same family-run team for electrical installations and the associated plastering and finishing work.
We undertake electrical projects across both residential and commercial settings, from smaller improvements to larger refurbishment work.

Commercial refurbishment work can involve several stages, with electrical alterations often taking place before walls and ceilings can be finished. Having electrical and plastering services available through GBL can make coordinating these stages more straightforward.
Our team can provide the required electrical installation before completing relevant plastering work as the project progresses. This combined approach is particularly useful for commercial refurbishments and fit-out projects where both trades are required.
