Emergency gas works
Elm Grove
Updated 23 December 2025
Our engineers are currently responding to a gas escape on Elm Grove in Portsmouth, located between its junctions with St Andrews Road and Victoria Road South. Because of where the pipe sits within the carriageway, an eastbound road closure is now in place between these junctions.
This closure will remain in place over the Christmas period. Repair work is progressing, and we expect to reopen the road during the first week of January 2026. All businesses on Elm Grove will remain open during our works, as per their individual normal and festive opening hours.
During this time, there will be no eastbound through‑traffic between St Andrews Road and Victoria Road South, and vehicles will not be able to exit St Andrews Road onto Victoria Road South. Westbound traffic is unaffected, and pedestrian access continues to be maintained. Bus routes in the area may also be impacted, so we encourage passengers to check with their service provider for the latest travel updates.
Roadworks in your area
It could be emergency work to keep you, and our network, safe. As this type of work is urgent and unplanned, we sometimes start work before it appears on the map.
We're sorry for disturbing you. In an emergency, we need to make the situation safe immediately and sometimes it can't wait until the morning. Watch our short film to find out more about why we have to work at night:
The engineering required for our project would not safely allow night-time work on a live gas supply. The infrastructure under the road is close to other critical utilities such as electricity, water, BT and broadband and we need to avoid these pipes and wires while working in the road.
There are many reasons why engineers may not be visible on site:
- To maintain gas supplies while replacing this gas main there are jobs that require the engineers to leave site
- They could be testing pressures on local governors around the area, collecting materials from local storage, carrying out mandatory health and safety paperwork in their van, or need network access
- The road may be being reinstated and they are waiting for the concrete to cure.
We’ll aim to put signs out to keep you informed.
Search for your road in our local gas works map to find out more about our work. You’ll need to change the date in the search bar so you can see our future work. Click on the gas flame icon that appears on your road to see details of what we’ll be doing in your road and when.
We will make sure emergency services are fully aware of the road closure and the planned diversion route. They will make sure their response teams are allocated from the quickest route. We will make sure vehicle access to properties located within the lane closure is maintained and will keep emergency services advised.
We look after the gas pipes in the south of England and across Scotland.
If you're not sure who manages the network of pipes that delivers your gas, use our postcode checker to find out if we deliver gas to your area
If we're not your supplier, the FindMySupplier website is able to let you know your gas transporter, your energy supplier and your MPRN.
The dates shown on the map are taken from the works permit we are granted which doesn’t always match the duration of the works required.
For example, the permit may be for one week but the work will only take three days to complete. This allows for flexibility and unforeseen circumstances.
There are many reasons why roadwork dates may be change and sometimes these are things that are outside of our control.
We appreciate it is frustrating when this happens and we will do what we can to minimise impact on you.
Our barriers must stay in place until it’s completely safe for us to remove them. Sometimes we’ll have barriers up, but our engineers won’t be there. This could be because we’re working on another section of the project, or we could have finished work and we’re waiting for the new road surface to set.
