Commercial and industrial electrical contractors, in-house since 1973
Rossair delivers commercial and industrial electrical work with its own NICEIC-registered engineers - power and distribution, lighting, EICR testing, emergency lighting and fire alarms, EV charging and planned electrical maintenance. One contractor across electrical and mechanical, so the plant room has one accountable name.
Electrical contracting for commercial and industrial buildings
Rossair is an electrical contractor for offices, schools and colleges, NHS and care estates, industrial units and multi-site portfolios. We design, install, test and maintain the electrical side of a building alongside the HVAC and mechanical plant we already look after - so a distribution board upgrade, a new lighting scheme or a five-yearly EICR is handled by engineers who know the whole building, not a separate trade brought in for the day. Every installation is certificated to BS 7671 and the paperwork lands in your compliance pack.
- Power and distribution - mains, sub-mains, distribution boards, 3-phase supplies and load assessments
- Lighting - LED upgrades, new lighting schemes and controls for offices, classrooms, wards and warehouses
- EICR and fixed wire testing with the remedial work done by the same engineers
- Emergency lighting and fire alarm systems - design, installation, testing and servicing
- Commercial and workplace EV charger installation
- BMS and controls wiring for HVAC plant, interfaces and fire-alarm cause-and-effect
- Planned electrical maintenance under an SFG20-scheduled contract, with reactive cover for contract clients

Chichester College Group - mechanical, electrical and building services across 11 campuses for over 20 years
Chichester College Group describes Rossair as having supported the group "for some 20 years across mechanical, electrical and building services, including full environmental control and design" across all 11 campuses. That is what in-house electrical looks like in practice: the same engineers who maintain the heating and ventilation also test the installation, fix the faults and certificate the work. The Wembley Health Centre decarbonisation - a live NHS building taken fully off gas and onto electric heat - ran on the same principle.
