Why roadworks are necessary
Infrastructure Upgrades: To maintain reliability and accommodate growing demand, we regularly upgrade our infrastructure. This includes laying new cables, upgrading existing ones, and installing state-of-the-art technology to keep your power supply stable and efficient.
Safety Enhancements: Safety is our top priority. Roadworks allow us to replace ageing infrastructure and make necessary improvements to prevent power outages and enhance safety for everyone.
Future-Proofing: As we move towards greener energy solutions, upgrading our electricity infrastructure is crucial. These improvements are a key part of ensuring that we can support sustainable energy sources and technologies in the future.

FAQs
Why do you undertake roadworks?
How long will it take?
This will depend on the complexity of works, each roadwork job is carefully planned and we will always communicate how long the works are expected to take prior to starting. Occasionally, we encounter unforeseen circumstances which can have a knock on effect to how long the works take - this is outside of our control, and we will ensure we communicate any extensions to work periods as quickly as possible.
Why didn’t these works get undertaken in conjunction with other utilities?
Although we try to coordinate these types of works as best we can to minimise disruption to residents, it isn't always possible. This can be due to different complexities within the separate utility projects. Where possible, we will always try to maximise the activity we can achieve, in partnership with government and other essential services.
Will I be able to access my property?
Yes, full access will be maintained throughout the works, unless otherwise stated. Our subcontractors Geomarine are very accommodating to ensure access is maintained.
In the event that we have closed a road we will post a diversion. These direction changes are designed to meet the requirements of all road users and the legal specification.
Will I be able to access my property if the road is closed between 9am and 4pm?
You will only be able to access your property by foot during this time, unless pre-arranged with the contractor. Access will be maintained for Emergency services.
How long will my electricity be off for?
If a planned shutdown is required, you should be formally notified by a shutdown letter a minimum of two days prior to the works. Shutdowns generally take place between 9am – 4pm.
Not all roadworks result in the need for the electricity supply to be isolated. The majority of our work is carried out live without any customer losing their electricity supply.
How long will the food in my fridge/freezer last?
Your fridge should stay cold for up to 4 hours. The food in your freezer should stay frozen for up to 48 hours in a full freezer (or 24 hours if it's half full), but these are estimates. Fridge and freezer temperatures will vary depending on their make and model. We recommend limiting the number of times you open the doors to these during this period to reduce the amount of cold air escaping.
