An M&E contractor for Bristol estates, not a directory listing

Search for an electrical contractor in Bristol and the first page is directories and one-van firms. That suits a landlord with a flat to certify. It does not suit a business park at Aztec West, a university estate, an NHS site or a distribution centre at Avonmouth, where the electrical work has to be programmed around the heating, the ventilation and the people in the building. That is the work Rossair does, with engineering teams based in Gloucestershire and the Basingstoke head office handling contract management, helpdesk and accounts. Multi-site and contract clients get a named account manager and the same engineers on every visit.

Frequently asked

Electrical contractors in Bristol - common questions

What electrical work does Rossair do in Bristol?

Commercial and industrial electrical contracting across Bristol: 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 Bristol and the surrounding area does Rossair cover?

All of Bristol - the city centre, Temple Quay, Clifton, Aztec West, Almondsbury, Filton, Avonmouth and Severnside - plus Portishead, Clevedon, Thornbury, Yate, Keynsham, Bath, Weston-super-Mare and North Somerset. Engineering teams are based in Gloucestershire, under an hour away on the M5.

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

Yes. Commercial EICR and fixed wire testing in Bristol 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.

Does Rossair cover Bath as well as Bristol?

Yes. Bath, Keynsham and the surrounding area are covered on the same basis as Bristol, from the Gloucestershire engineering teams. Multi-site clients with buildings in both cities are run under one contract with one account manager.

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

Yes, and it 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.
