Electrical contracting for the M4 corridor, from the Gloucestershire side

Swindon is a logistics and business-park town: distribution centres at South Marston and the Keypoint and Symmetry parks, offices at Windmill Hill and Kembrey Park, the Great Western Hospital estate and a ring of schools and colleges. Those buildings need an electrical contractor that can plan a distribution upgrade, an EICR programme or an EV charging rollout around a live operation. Rossair’s engineering teams are based in Gloucestershire, 40 minutes up the A419, with contract management, helpdesk and accounts at the Basingstoke head office, and contract clients get a named account manager and the same engineers on every visit.

Frequently asked

Electrical contractors in Swindon - common questions

What electrical work does Rossair do in Swindon?

Commercial and industrial electrical contracting across Swindon: 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 Swindon and Wiltshire does Rossair cover?

Swindon, South Marston, Kembrey Park, Windmill Hill, Highworth, Royal Wootton Bassett, Cricklade and Marlborough, plus Chippenham, Malmesbury, Calne and Cirencester along the M4 and A419. Engineering teams are based in Gloucestershire, about 40 minutes away.

Can Rossair install EV charging at a Swindon distribution centre or business park?

Yes. Commercial EV charging for staff bays and fleet depots starts with a supply and load assessment, then dynamic load management, the DNO application where a supply upgrade is needed, and installation of 7 kW to 22 kW AC and DC rapid chargers by NICEIC-registered engineers. Swindon’s logistics sites are a natural fit for fleet charging planned alongside the building’s own demand.

Can Rossair carry out a commercial EICR on our Swindon premises out of hours?

Yes. Commercial EICR and fixed wire testing in Swindon is phased board by board around occupied buildings - evenings, weekends and term breaks where circuits cannot be isolated during the day - with remedial work carried out by the same engineers and the certificate filed in your compliance pack.

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

Yes. 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.
