Rossair is a commercial and industrial electrical contractor with engineering teams based in Gloucestershire, working across Gloucester, Cheltenham, Stroud, Tewkesbury, Cirencester and the M5 corridor. We install and upgrade power, distribution and lighting, carry out EICR testing, install and service emergency lighting and fire alarm systems, and run electrical maintenance contracts for offices, schools, care homes, NHS buildings and industrial units. Electrical is delivered by the same engineers who look after the mechanical plant, so one contractor covers the whole building.

An M&E contractor for Gloucestershire estates, not a one-van electrician

Gloucestershire has plenty of good local electricians. What it has fewer of are contractors sized for an estate: a multi-site school trust, an NHS building, a care group, a business park or an industrial site where the electrical work has to be programmed around the heating, ventilation and the people in the building. That is the work Rossair does, and in Gloucestershire it is done by engineering teams based in the county - not dispatched from the south coast for the day. The Basingstoke head office handles contract management, helpdesk and accounts, and multi-site or contract clients get a named account manager and the same local engineers on every visit.

Designed, installed and certificated to BS 7671 by Rossair engineers. Electrical services.

EICR and fixed wire testing

Periodic inspection and testing of the fixed installation, every circuit tested and every observation coded C1 to C3, with the remedial work carried out by the same engineers. Phased around occupied buildings - evenings, weekends and term breaks. Commercial EICR.

Emergency lighting and fire alarms

Electrical maintenance contracts

Planned electrical PPM scheduled to SFG20 - distribution boards, emergency lighting, fire alarm servicing and the EICR cycle - usually on the same contract as the HVAC plant. Contract clients in Gloucestershire have 24/7 reactive cover, 365 days a year, from engineers based in the county, with response times agreed in the contract and a 24-hour job report after every visit. Maintenance contracts.

Gloucester and Cheltenham

Commercial electrical contractors in Gloucester

Gloucester is where the county’s industrial and logistics estate sits - Gloucester Business Park, Quedgeley, Innsworth, the docks and the units along the A38 and M5 - alongside the Gloucestershire Royal Hospital estate, the college and a dense stock of offices and schools. Rossair engineers based in Gloucestershire handle the electrical work for all of it: distribution and 3-phase upgrades for industrial units, EICR programmes phased around production and term time, emergency lighting and fire alarm servicing, EV charging for staff and fleet bays, and planned electrical maintenance alongside the mechanical plant.

Commercial electrical contractors in Cheltenham

Cheltenham’s commercial estate is offices, professional firms, independent schools and the college, Cheltenham General Hospital, retail and hospitality, and a growing cyber and technology cluster around the west of the town. The work is compliance-led and occupancy-sensitive: commercial EICRs out of hours, emergency lighting and fire alarm testing logged for the responsible person, lighting and power upgrades planned around trading hours, and electrical maintenance contracts that keep the certificate dates tracked. Rossair engineers based in Gloucestershire cover Cheltenham, Bishop’s Cleeve, Charlton Kings and Winchcombe as local ground.

Where we work in Gloucestershire

Gloucester, Cheltenham, Stroud, Tewkesbury, Cirencester, Tetbury, Dursley, Lydney and the Forest of Dean, and the industrial and business estates along the M5 and A417. Offices, schools and colleges, care homes, NHS and community health buildings, warehouses and manufacturing units, and multi-site portfolios that run into Wiltshire, Oxfordshire and Bristol.

Why estates stay with Rossair

We show up. We do it properly. We send the paperwork. A named account manager, the same engineers year after year, and a compliance pack - certificates, EICRs, emergency lighting and fire alarm logbooks - your auditor can actually use. Rossair has been looking after commercial building services since 1973, and the contracts that last longest are the ones where nobody has to chase us.

Frequently asked

Electrical contractors in Gloucestershire - common questions

What electrical work does Rossair do in Gloucestershire?

Commercial and industrial electrical contracting across Gloucestershire: power and distribution upgrades, lighting and LED schemes, EICR and fixed wire testing, emergency lighting and fire alarm systems, commercial EV charger installation and planned electrical maintenance contracts. All work is carried out by Rossair engineers and certificated to BS 7671.

Which parts of Gloucestershire does Rossair cover?

Gloucester, Cheltenham, Stroud, Tewkesbury, Cirencester, Tetbury, Dursley, Lydney and the Forest of Dean, plus the business and industrial estates along the M5 and A417. Multi-site clients with buildings beyond the county - Swindon, Bristol, Oxfordshire - are covered under the same contract.

Does Rossair have engineers based in Gloucestershire?

Yes. Rossair has engineering teams based in Gloucestershire, so planned and reactive electrical work in Gloucester, Cheltenham, Stroud, Tewkesbury and Cirencester is carried out by local engineers. Contract management, helpdesk and accounts run from the head office in Basingstoke, Hampshire, and one telephone number - 01420 566822 - reaches both.

Can Rossair carry out an EICR on our Gloucester or Cheltenham premises?

Yes. Commercial EICR and fixed wire testing is one of the most common pieces of electrical work we do, phased around occupied buildings and with any remedial work carried out by the same engineers. Most commercial premises need an EICR every five years and industrial premises every three.

Can electrical and HVAC maintenance be combined for a Gloucestershire site?

Yes, and that is the model that suits an estate best. Electrical PPM - distribution boards, emergency lighting, fire alarm servicing and the EICR cycle - goes on the same SFG20 schedule as the heating, ventilation and air conditioning, under one contract with one account manager and one compliance pack.

Is Rossair a NICEIC-registered electrical contractor?

Yes. Rossair is NICEIC registered for electrical installation and for inspection and testing, so installation certificates and EICRs are issued under the scheme. Rossair is also Gas Safe and REFCOM F-Gas registered and Constructionline and SafeContractor accredited.
