What a consumer unit does and why it matters
A consumer unit is the control centre of your electrical installation. It distributes power, protects circuits, and isolates faults. Modern systems use protective devices that react quickly to danger, reducing the risk of electric shock and fire.
If you have an older fuse board, a consumer unit upgrade in Leeds or Bradford improves safety, reduces nuisance tripping, and prepares your property for modern electrical demand. It also makes future additions simpler, with space, clear labelling, and correctly rated protective devices.
In many cases, upgrades are recommended following an electrical inspection, where outdated equipment or missing protection is identified.

What is included in a professional consumer unit upgrade in Leeds and Bradford
A consumer unit upgrade in Leeds and Bradford is more than replacing a fuse box. It is a full safety and compliance process that ensures your electrical installation is safe, correctly protected, and ready for modern use.
- New metal consumer unit with non-combustible enclosure
- Main switch isolator and correctly rated protective devices
- RCBO protection on individual circuits for improved fault isolation
- Surge Protection Device where required or recommended
- Clear circuit schedule with accurate labelling
- Verification of earthing and main protective bonding
- Replacement of meter tails where required
- Full testing of all circuits before energising
- Electrical Installation Certificate and recorded test results
RCBOs, split load boards, and which to choose for your consumer unit upgrade
An RCBO combines overcurrent protection with residual current protection on a single circuit. This means a fault on one circuit does not affect others, making it the most effective option for improving safety and reducing nuisance tripping during a consumer unit upgrade in Leeds or Bradford.
Split load boards use a smaller number of RCDs shared across multiple circuits. This can be a more budget-friendly option for some properties, but the trade-off is that a single fault can remove power from several circuits at once.
We explain both options clearly during the survey so you can choose the right setup for your property, whether you need a consumer unit replacement in Leeds or a new installation in Bradford.
Surge protection explained
A Surge Protection Device reduces damage from transient overvoltages. These short spikes can occur during switching events or network disturbances. Sensitive equipment such as routers, televisions, chargers, and appliances can be affected.
As part of a consumer unit upgrade in Leeds or Bradford, we often install a Type 2 surge protection device within the new board. It operates automatically and requires no input from you. Where it is not required, we explain the reasoning clearly. If it is recommended or requested, it is installed and recorded on your certification.
If you are unsure whether surge protection is required, we can assess your installation during an electrical inspection.
AFDDs and when they are worth adding to your consumer unit
Arc Fault Detection Devices monitor for dangerous arcing conditions that standard protective devices may not detect. They are recommended in certain higher-risk situations, including properties with older wiring, damaged cables, or increased fire risk.
AFDDs increase the cost and space required within the board, so they are not always necessary. As part of a consumer unit upgrade in Leeds or Bradford, we explain where they are beneficial, what they cost, and whether they are appropriate for your installation. If required, we design the consumer unit layout to accommodate them correctly.
Earthing, bonding, isolators, and meter tails
A safe consumer unit depends on a safe supply. Before any work begins, we confirm the earthing system type and check that main protective bonding is adequate. We also assess meter tails and main switches to ensure they are correctly sized and rated as part of a consumer unit upgrade in Leeds or Bradford.
- Earthing system checked (TT, TN-C-S, or TN-S)
- Main bonding to gas and water verified and upgraded where required
- Isolator switch fitted or used if already present for safe working
- Meter tails upgraded where the existing size is not suitable
If supplier equipment seals need to be removed, we follow the correct process and plan this in advance so the work runs smoothly.
Special notes for TT earthing systems in Leeds and Bradford
On TT systems, the earth path is provided by an electrode in the ground. These installations behave differently from PME systems and require careful design to achieve correct disconnection times.
As part of a consumer unit upgrade in Leeds or Bradford, TT systems often use an RCD main switch with RCBO protection or a fully RCBO-based arrangement, depending on the installation and measured values.
We confirm electrode condition, measure earth electrode resistance, and verify bonding sizes. Protective devices are then selected to suit the installation so compliance with BS 7671 is achieved. All results are recorded on the test schedule.
Day of installation: consumer unit upgrade process
A clear plan keeps disruption low. Here is how a typical consumer unit upgrade in Leeds or Bradford is carried out from arrival to handover.
1. Arrival and safe isolation
We confirm the scope, isolate the supply, and verify dead using approved test instruments. Floors and worktops are protected before work begins.
2. Remove old equipment
The existing board is documented, circuits are identified, and cabling is carefully removed. We check for signs of heat damage or poor connections.
3. Install and prepare new enclosure
The new metal consumer unit is installed level and secure. Entries are fitted with glands and grommets to protect cables and maintain compliance.
4. Fit devices and terminate circuits
Main switch, RCBOs, and surge protection are installed. Conductors are terminated correctly, torqued to specification, and clearly identified.
5. Test and label
Full testing is carried out including continuity, insulation resistance, polarity, RCD performance, and earth fault loop impedance. Labels are clear and easy to understand.
6. Power on and handover
The installation is energised and verified under load. We explain the layout and provide your Electrical Installation Certificate along with any recommendations.
Preparing your property for a consumer unit upgrade
A little preparation helps your consumer unit upgrade in Leeds or Bradford run smoothly and reduces disruption on the day.
- Clear access to the consumer unit, meter, and any understairs or cupboard areas
- Move fragile or valuable items near the working area
- Share details of appliances or equipment that may be affected by power isolation
- Confirm parking and access for tools and materials
- Agree suitable start and finish times in advance
If you need power during the day for medical or business reasons, let us know in advance. We can plan a safe temporary supply where practical.
If you are unsure whether your installation is ready for an upgrade, we can assess it with an electrical inspection before booking.

Frequently asked questions about consumer unit upgrades in Leeds and Bradford
1. How long does a consumer unit upgrade take
Most consumer unit upgrades in Leeds and Bradford take between half a day and a full day, depending on the number of circuits, access, and the condition of the existing installation. Larger or more complex properties may take longer. We confirm a realistic timeframe before starting.
2. Will I be without power
Yes, the power will need to be isolated during the upgrade for safety. This usually lasts several hours. We plan the work carefully to minimise downtime and can discuss temporary solutions if power is needed for medical or business reasons.
3. Do you test the entire property
Yes. As part of a consumer unit upgrade, we carry out full testing of all circuits including continuity, insulation resistance, polarity, RCD performance, and earth fault loop impedance. This ensures the installation is safe before it is re-energised.
4. Do you provide certificates
Yes. You receive an Electrical Installation Certificate along with test results and a clear circuit schedule. This confirms the work complies with current BS 7671 regulations and is suitable for landlords, homeowners, and businesses.
5. Can you reuse my old breakers
In most cases, no. Older breakers are not compatible with new consumer units and may not meet current safety standards. We install new, correctly rated protective devices to ensure full compliance and reliability.
6. Can you add solar, EV charging, or smart systems later
Yes. We design consumer units with spare capacity and future expansion in mind. This makes it easier to add EV chargers, solar systems, or smart home upgrades without needing another board replacement.
