Consumer Unit Upgrade Manchester
If you are installing solar panels or a battery storage system, there is a strong chance your existing consumer unit is not up to the job. Many homes across Manchester still have older-style fuse boards with rewirable fuses or MCBs without RCD protection. These boards lack the capacity, the safety devices and the spare ways needed to safely integrate modern renewable energy systems. Attempting to connect a solar inverter or hybrid battery system to an outdated board is a code violation that no reputable installer should agree to.
Manchester Renewables upgrades consumer units across Greater Manchester as a standalone service or as part of a wider solar or battery installation. We fit modern, metal-clad consumer units with dual RCD protection or individual RCBO circuits, Type 2 surge protection devices, and sufficient spare capacity for future renewable energy additions. Every upgrade is carried out by our NIC/EIC Approved electricians, fully tested and certified with Building Control notification included.
What Is Included?
Full Electrical Assessment
Before any work begins, we carry out a thorough assessment of your existing wiring, earthing arrangement and current demand. This identifies whether a straightforward board swap is sufficient or whether additional work such as earthing upgrades or circuit modifications are needed.
Metal-Clad Consumer Unit Installation
We install Amendment 3-compliant metal consumer units from leading manufacturers including Hager, MK and Schneider. All units feature dual RCD or RCBO protection on every circuit for maximum safety.
Surge Protection Device (SPD)
Type 2 surge protection is fitted as standard on all consumer unit upgrades. This protects your solar inverter, battery system and other connected equipment from damaging voltage spikes caused by lightning strikes or grid switching events.
Dedicated Renewable Energy Circuits
We install dedicated circuits for solar PV and battery storage with correctly rated RCBOs and appropriate cable sizing. This future-proofs your electrical system for additional low-carbon technology.
Testing, Certification & Building Control
Every consumer unit upgrade is fully tested with calibrated instruments, documented with an Electrical Installation Certificate (EIC), and automatically notified to Building Control through our NIC/EIC registration.
Part P Building Regulations (England & Wales): Mandatory compliance for all consumer unit replacements
Consumer unit replacements are notifiable work under Part P of the Building Regulations. This means the work must either be carried out by an electrician registered with a Competent Person Scheme (such as NIC/EIC) or inspected and signed off by your local Building Control body. Using an unregistered electrician means no Building Regulations Compliance Certificate, which can cause serious problems when selling your property and may invalidate your home insurance. Our NIC/EIC registration allows us to self-certify all consumer unit work.
Why It Matters
- Older consumer units with rewirable fuses provide no RCD protection against electric shock
- Solar inverters and battery systems require dedicated circuits with specific protective devices
- Plastic consumer units are no longer compliant with BS 7671 Amendment 3 — metal enclosures are mandatory
- Insufficient spare capacity in your fuse board means renewable energy systems cannot be safely connected
Cost Guidance
A standard consumer unit upgrade in Manchester typically costs between £500 and £900 for a straightforward like-for-like replacement with a modern metal-clad board. If additional work is required — such as earthing upgrades, circuit modifications or additional ways for solar PV and battery storage circuits — costs range from £800 to £1,200. When a consumer unit upgrade is carried out as part of a solar panel or battery storage installation, we bundle it at a reduced rate. All prices include the board, all protective devices, testing, EIC certification and Building Control notification.
