signage.

Substation signage, wind farm markers, solar panel warnings, high-voltage labels, and infrastructure signage that meets the Electricity at Work Regulations.

Energy infrastructure carries some of the highest stakes for signage compliance. The Electricity at Work Regulations 1989, the Construction (Design and Management) Regulations 2015 (for new build and major upgrades), and the various asset-owner specifications (DNO standards, transmission operator standards, renewable generator policies) all impose specific signage requirements.

Direct Signs supplies to EDF, National Grid, Octopus Energy, and a range of independent renewable generators across solar farms and onshore wind. Our signage is specified for the unusual environments these assets sit in: rural exposure, climbing access, helicopter underflight, and security-controlled compounds.

Common signage we supply: "Danger high voltage" warnings, substation perimeter signs, "Authorised personnel only" prohibition, climbing prohibition, helipad markers, solar farm boundary signs, wind farm asset ID, BESS (battery storage) hazard signs, fire risk and isolation point signage, and bespoke wording for unusual asset configurations.

Common questions

Energy sector FAQs

Do you meet DNO and transmission operator signage standards?
We supply to the major UK DNOs and to National Grid contractors. Each operator has its own specification document; tell us which you are supplying for and we will produce to that spec.

What materials are best for substation perimeter signs?
Aluminium composite (Dibond) for long-life external use, or pressed aluminium for high-impact / vandalism-prone locations. Both materials carry our standard 7-year minimum outdoor life.

Can you produce signage for solar and battery storage sites?
Yes. Solar farm boundary signs, BESS hazard warnings, fire isolation points, emergency contact info, and EICR-aware electrical hazard signs are all part of our renewable energy signage range.
