“Going off grid” with electricity can mean two different things: producing more of your own power while staying connected, or permanently disconnecting from the network. The first is simple and reversible. The second is a big decision that is hard and costly to undo.
Option 1: stay connected and reduce your dependence
- Add solar panels and, if it suits you, a battery, and use the grid as a backup.
- You keep a safety net and the option to export surplus power, subject to the rules of your supplier and the schemes available.
- You pay a standing charge for the connection, but avoid the risk of a failed system leaving you without power.
Option 2: fully disconnect
Permanent disconnection means the network operator removes your connection, and your supplier closes your account. The general steps are:
- Contact your electricity supplier. The supplier owns the meter and manages your account.
- Contact your distribution network operator (DNO). This is the company that owns the local network and physically disconnects the supply. Your postcode determines which one it is.
- Agree the work and the cost. The DNO will quote based on what needs to be done, which may involve digging to reach their equipment.
- Wait for the work. Low-voltage domestic disconnections are often quoted at a few weeks, but timescales vary.
- Close your accounts and keep records.
The risks of disconnecting
- Reconnecting can be expensive and slow. Do not assume you can restore the supply cheaply later.
- Resale and mortgages: a home with no mains supply is a narrower market.
- Insurance and safety: your own system must be designed and installed safely.
- Winter shortfall: a system that works in summer may fail in December.
Do you have to disconnect to be off grid?
No. Many people stay connected but generate most of what they use. Others keep a live but unused connection as insurance. Use the numbers to decide: work out your loads, compare the cost of a system that covers the worst winter week against the cost of keeping a connection. See how much battery you need and what off-grid solar costs.
Sensible steps before any decision
- Measure your loads: use our Power & Battery Load Planner.
- Get design and quotes from competent installers, with winter figures in writing.
- Model costs with the Budget & Cost Planner.
- Ask your DNO and supplier what disconnection and reconnection would involve.
FAQ
Is it legal to disconnect from the grid? Yes.
Can I disconnect myself? No. Only your supplier and network operator can remove the meter and disconnect the supply; never touch service equipment yourself.
Can I go back on grid later? Often, but possibly at a significant cost and delay.
