Back in April 2023, Ofgem rolled out changes to the way Distribution Network Operators (DNOs) charge for upgrading your electricity supply. The reforms, known as the Access Significant Code Review (Access SCR), meant that in many cases, businesses could request more capacity without footing the full bill for upstream reinforcement costs.
So, what’s changed in 2025? Are those savings still available – or has the door closed?
Let’s recap: what changed in 2023?
Under the old rules, if you asked your DNO for more capacity, you could end up being charged for reinforcement works far beyond your own site – even if those upgrades benefitted other users, too.
The Access SCR flipped that on its head. From 1 April 2023, the cost of most wider network reinforcements (up to certain thresholds) has been picked up by the DNO, rather than the end user. That made it much cheaper get more capacity – sometimes even cost-free.
What’s happening now?
The reforms are still in place, and many businesses are continuing to benefit from reduced costs when requesting additional capacity. However, the wider electricity network is under pressure. Demand for connections has skyrocketed – driven by the transition to electric vehicles, heat pumps, battery storage and low-carbon technologies.
To manage that demand and prioritise projects that are genuinely ready to go, Ofgem has introduced further changes in 2024–2025, including:
- A “first ready, first connected” approach, replacing the old first-come, first-served queue.
- More scrutiny of connection applications to make sure network capacity is used efficiently.
- Investment in network upgrades to accommodate growing demand.
So, can I still get free upgrades?
In many cases, yes – though it’s not quite as simple as it was a year ago.
The Access SCR is still in effect, meaning DNOs should continue to cover the cost of many reinforcement works. However, connection offers are now subject to tighter timescales, and DNOs may require more detail to assess whether your request is realistic and ready.
In practice, that means:
- You should still ask for the extra capacity you need – don’t assume it’ll be expensive.
- Your DNO may ask for evidence (such as planning permission, business cases or expected load profiles).
- Costs are typically lower than pre-2023, but may not be entirely free, especially for complex or large upgrades.
Our advice
If you’re considering expanding your site, electrifying more equipment, or simply want more headroom in your supply, it’s worth checking in with your DNO or speaking to a consultant who can help.
We recommend:
- Reviewing your existing Maximum Import Capacity (MIC) – is it still fit for purpose?
- Getting quotes for an upgrade – this doesn’t commit you, but it gives you a clear picture of likely costs.
- Engaging early – connection timescales can still be lengthy, so it’s best not to leave it too late.
