Commercial Contractors UK
UK-wide commercial and industrial work
Facilities managers and main contractors choose Nulectrics for commercial and industrial projects because we bring electrical, mechanical and fire and security under one contract, backed by NICEIC, ECA, Constructionline Gold and SSIP accreditation. You get commercial-grade documentation, full insurance and out-of-hours cover as standard, and a direct line to the team when a site needs a fast response.
Why use one contractor for commercial electrical, mechanical and fire and security?
Briefing one contractor across all three trades removes the coordination risk of juggling separate firms: no gaps at commissioning, one snagging list, one set of certificates and a single point of accountability. Nulectrics works across office, retail, industrial, healthcare and warehousing sites, from one-off installations through to planned maintenance under an agreed SLA.

What commercial clients say
★★★★★We used Nulectrics for some work needed doing in our warehouse. From start to finish AJ was great. Gave me all the information needed, great price, service and timings top notch. Will 100% be using again. Highly recommend.
MOwner responseHello, Really appreciate this, it was really nice to meet you guys and also working with you. We will be sorting out the next lot of work you require very soon. See you next time. Aj Nulectrics
★★★★★Aj has been extremely helpful in various jobs we have asked him to look at for the Salvation Army in Chippenham. (No job too small!!) He explained what needed doing and gave his recommendation for the best solution. He also sought to find the cheapest but most efficient means of 'repair/replacement' and was mindful that we have to work within a budget. Would highly recommend him and his work.

Commercial questions we get asked
Do you work outside Wiltshire?
Yes. Commercial and industrial work is delivered UK wide from our base at Methuen Park in Chippenham, and past projects include hospital canopy lighting at Northwick Park in Harrow. Our domestic work is regional, covering Wiltshire, Bath, Bristol and the surrounding towns, so tell us where your site is and we will confirm what we can do.
Can you cover electrical, mechanical and fire and security on one contract?
Yes. That is the reason the three trades sit together here. Briefing one contractor across all three removes the coordination overhead between separate suppliers, and it gives you one point of contact when something needs chasing. Some regulated work, such as gas, F-Gas and BAFE-certified fire alarm design, is carried out by accredited specialists that we manage as part of the package.
How often does a commercial property need an EICR?
There is no fixed interval set in law. The Electricity at Work Regulations 1989 require the installation to be maintained so that it does not cause danger, and periodic inspection is how you evidence that. IET Guidance Note 3 recommends maximum intervals of five years for offices and shops, three years for industrial premises, and one year for leisure premises. Your insurer or your lease may set something shorter, so check both.
Who is responsible for electrical safety in a leased building?
Regulation 3 of the Electricity at Work Regulations 1989 puts the duty on the duty holder, which is whoever has control of the installation. Under a full repairing and insuring lease that is usually the tenant for everything inside the demise, with the landlord retaining the common parts and the incoming supply. The lease is the document that decides it, so read it before assuming.
What standard do commercial fire alarm systems need to meet?
Fire detection and alarm systems in non-domestic premises are designed, installed and maintained to BS 5839-1. The current edition is BS 5839-1:2025, which superseded the 2017 edition on 30 April 2025. Anything quoting BS 5839-1 without a year is worth querying.
Are you NICEIC and ECA approved?
Yes. We are a NICEIC Approved Contractor and ECA members, and we also hold Constructionline Gold and are SSIP registered. The Constructionline and SSIP certificates are linked on this page, and everything is listed in full on the accreditations page. If you need copies for prequalification, ask and we will send them.
