Want extra circuits for an EV charger, solar panels or a renovation? On this page you'll find an indication of the cost and the factors that affect the price.

What determines the cost?
Extending a meter cupboard is often cheaper than a complete replacement. You keep your existing unit and I add extra circuits or an RCD.
Whether an extension is possible depends on the space in your unit and the condition of the installation. Sometimes I still recommend a replacement, for safety and to be ready for the future.
Every situation is different. That's why I always give a tailored quote after assessing your meter cupboard or based on a photo.
Example scenarios
Extension with 1 or 2 circuits
For an extra circuit or a small renovation. Often one extra breaker and possibly a busbar is enough. A quick job with limited costs.
Extension for an EV charger
An EV charger needs its own circuit and often a separate RCD. I extend your unit and connect the charger. One quote for the lot.
Extension for solar panels
The solar panel inverter must be on its own circuit. I add the circuit and connect the inverter to the standards.
Price indication
Your tailored quote always takes precedence.
| Extra circuit | € 44,89 incl. VAT |
|---|---|
| EV charger connection in the consumer unit, from | € 424 incl. VAT |
| EV charger connection in the consumer unit, up to | € 962 incl. VAT |
| Installing three-phase power | € 545 incl. VAT |
| For comparison: complete three-phase meter cupboard replacement | from € 2.699,99 incl. VAT |
Factors that affect the price
- Number of extra circuits: more circuits means more breakers and cabling.
- RCD: sometimes an extra RCD is needed; that affects the price.
- Access: I work faster in an easily accessible cupboard.
- Condition of the unit: if the unit isn't suitable for extension, replacement may be needed.
- Grid operator: when upgrading the connection (for example to three-phase), the grid operator and the lead time play a part.
Questions about extending a meter cupboard
What does a meter cupboard extension cost?
The cost depends on the number of extra circuits, whether a new RCD is needed and the access. An extension with one or two circuits is often cheaper than a complete replacement. Request a tailored quote.
Can my meter cupboard be extended for an EV charger?
In many cases, yes. An EV charger needs its own circuit and often an RCD. I assess your unit and tell you what's needed and what it costs.
Do solar panels need their own circuit?
Yes. The solar panel inverter must be on its own circuit. I add the circuit and connect the inverter to the standards.
When is replacing better than extending?
If your consumer unit is outdated (for example with screw-in or porcelain fuses) or has no room for a safe extension, I often recommend a complete replacement. I explain the options in the quote.
Can I get a quote without you coming round?
Yes. I give a tailored quote after assessing your meter cupboard or based on a photo.
Is a quote for an extension free of obligation?
Yes. You get a transparent quote. I only start the work after you agree. If more turns out to be needed on site, I discuss it with you first.

From my knowledge base, in plain language.
How many circuits do you need in your consumer unit?
Work it out room by room instead of guessing a number. And add four spare modules: that costs next to nothing now and saves a whole new consumer unit later.
