Wrexham (Wales Times) November 13, 2026 – Homes across parts of uk/local/wrexham/">Wrexham have been left without electricity as engineers carry out emergency repairs to an underground cable fault in the LL11 postcode area.

As reported by The Leader, the power cut affects 10 postcodes in the LL11 area. The electricity network operator said the fault was reported at 10.46am, and engineers needed to switch off supplies at 11.50am so that repairs could be carried out safely.

The operator said: “We have to turn the power off in the LL11 postcode area of Wrexham at 11:50 so our engineers can safely carry out emergency repairs to an underground cable fault.”

It added: “We aim to restore power by 13/11/2026, 16:00.”

The outage remained listed as active under reference INCD-698278-r in the information reported by The Leader. The operator said the restoration time was an aim and that it would update its message if the situation changed.

Which areas are affected?

The outage covers 10 postcodes in the LL11 area of Wrexham. The Leader reported that the affected postcodes were listed in the operator’s outage information, although the full list was not included in the extract available from the report.

The electricity network operator warned that the outage area shown on its map is approximate. It said the mapped area may not reflect the exact properties affected.

That means some households within the LL11 area may be affected while others nearby may retain power. Residents who are unsure whether their property is included have been directed to the operator’s outage information.

Why has the power been switched off?

The cut is not described as a routine maintenance outage. According to the operator’s message reported by The Leader, it is linked to an underground cable fault requiring emergency repairs.

Engineers switched off electricity supplies at 11.50am. The operator said this was necessary so that its engineers could work safely on the faulty underground cable.

The operator’s message said: “To protect your equipment, please switch off and unplug all electrical appliances, including your boiler.”

It added: “We will update this message if the information changes. We apologise for the inconvenience and thank you for your patience.”

When will electricity return?

The latest stated restoration time is 4pm on Friday, 13 November 2026. The Leader reported that this could change depending on the progress of the repairs.

The operator said it aimed to restore supplies by that time. It did not provide a revised estimate in the information cited in the report.

Residents affected by the outage have been advised to unplug electrical appliances while the emergency repairs take place. The advice includes boilers, which can be affected by interruptions to electricity supply.

What should residents do?

The operator’s advice, as reported by The Leader, is for residents to switch off and unplug electrical appliances, including boilers.

This is intended to protect equipment when power returns. Electrical appliances can restart automatically after an outage, which may create a risk if they are left switched on.

Residents have also been advised to monitor the operator’s updates. The operator said it would update its message if the information changed.

Are other Wrexham postcodes affected?

Yes. On the same day, The Leader separately reported that nine Wrexham postcodes were affected by two planned outages connected with network upgrades.

According to The Leader, the first planned outage affected six postcodes and was expected to be restored by 1pm. It was listed under reference INCD-932829-f.

A second planned outage affected three further Wrexham postcodes and was expected to be restored by 4pm. It was listed under reference INCD-1449823-s.

The Leader reported that the planned work involved temporarily switching off electricity supplies so engineers could safely upgrade the network. Residents affected by either planned outage should have received a letter in advance explaining the work and the potential interruption.

The operator said, according to The Leader: “The electricity supply to your premises may currently be affected by planned work. You should have received a letter explaining this.”

It added: “We apologise for any inconvenience caused by the interruptions.”

How is this different from the emergency cut?

The emergency outage and the planned outages are separate incidents, although both were reported in Wrexham on 13 November 2026.

Incident	Cause	Number of postcodes	Restoration time
Emergency outage	Underground cable fault requiring emergency repairs	10	4pm, 13 November 2026
Planned outage one	Network upgrade work	6	1pm, 13 November 2026
Planned outage two	Network upgrade work	3	4pm, 13 November 2026

The emergency outage was reported at 10.46am, with supplies switched off at 11.50am. The planned outages were already scheduled work, and affected residents were told they should have received advance letters.

What has the operator said?

The electricity network operator’s statement, quoted by The Leader, said engineers had to turn the power off in the LL11 postcode area at 11.50am to carry out emergency repairs safely.

The operator said:

“We aim to restore power by 13/11/2026, 16:00.”

It also said:

“To protect your equipment, please switch off and unplug all electrical appliances, including your boiler.”

The operator apologised for the inconvenience and thanked residents for their patience. It said it would update its message if the information changed.

Background to the development

Wrexham is served by SP Energy Networks for electricity distribution, according to information published by Selectra. The company covers parts of North Wales, including Anglesey, Gwynedd, Conwy, Denbighshire, Flintshire and Wrexham.selectra.co+1

Underground cable faults can require engineers to isolate a section of the local network before repairs begin. This is intended to allow work to be carried out safely, but it can mean that homes and businesses in the affected area lose electricity temporarily.

The operator’s outage reference for the Wrexham emergency repair is INCD-698278-r. The reference is used to identify the specific incident in the network operator’s outage information.

The restoration time of 4pm was described as an aim rather than a guaranteed completion time. The operator said updates would be provided if the position changed.

Prediction: how this may affect residents

For residents in the affected LL11 postcodes, the immediate impact is likely to be disruption to household electricity use until supplies are restored. Households may need to avoid using electrical appliances until power returns, particularly boilers and other equipment that could restart automatically.

People working from home, caring for relatives, or relying on powered medical equipment may need to make alternative arrangements if the outage lasts beyond the stated restoration time. The operator has advised residents to unplug appliances, which may reduce the risk of damage when electricity is restored.

Local businesses in the affected area could also face temporary disruption if tills, refrigeration, lighting, communications equipment or computer systems lose power. The available reporting does not identify specific businesses affected by this outage.

If the repairs are completed by 4pm as planned, the disruption should be limited to several hours. If the work takes longer, the operator has said it will update its outage information, and residents should follow those updates rather than assume power will return at the stated time.
