How Much Does a Consumer Unit Replacement Cost in Kettering?

Consumer unit replacement is one of the most common electrical upgrades homeowners ask about, but it is also one of the easiest jobs to underestimate. The visible part is the new board on the wall. The important part is the testing, preparation, certification and making sure the existing wiring can work safely with modern protection.

In Kettering and across Northamptonshire, costs vary because houses vary. A small modern property with accessible wiring and good earthing is not the same as an older house with additions, outbuildings, old lighting circuits and unclear labelling. A good quote should explain what is included and what might change if testing reveals hidden faults.

What Normally Affects the Price?

The final quotation reflects the work needed at the property rather than the consumer unit alone. The main factors are:

• The number of circuits requiring protective devices, testing and labelling.
• The condition and configuration of the existing wiring.
• Defects revealed during inspection or testing.
• The condition and adequacy of earthing and bonding.
• Meter tails, main-switch arrangements and the incoming supply configuration.
• Access to the board and the time needed to identify poorly labelled circuits.
• Asbestos-containing equipment or enclosures that require specialist handling.
• Any additional remedial work needed before circuits can be safely energised and certified.

Any necessary additional work will be explained and priced before it is carried out.

Earthing, Bonding and Existing Wiring

Before a consumer unit is replaced, the electrician needs to check the earthing and bonding. Main protective bonding to gas and water services is a key safety requirement, and it can affect whether the board can be changed without additional work. If bonding is missing, undersized or inaccessible, this may need correcting as part of the job.

Existing wiring condition matters too. A modern consumer unit with sensitive RCD or RCBO protection may reveal faults that an older fuse box did not show. That does not mean the new board caused the problem. It means the new protection is detecting leakage, damaged insulation or borrowed neutrals that should be addressed.

Testing and Certification Are Part of the Cost

Consumer unit replacement is notifiable electrical work. You should expect an Electrical Installation Certificate and building control notification through a competent person scheme where applicable. The certification is not an optional extra; it is part of doing the job properly.

Pre-work checks can include inspection, basic circuit testing and discussion of any concerns. After installation, each circuit must be tested and results recorded. If a circuit fails testing, remedial work may be needed before it can be safely energised or certified. This is why a quote should be clear about what is included and how additional faults are handled.

If a property has wider uncertainty, an EICR can sometimes be useful before planning a board replacement, especially for older homes, rentals or properties with no recent electrical records.

What an Entigen Standard Quotation Includes

Our standard consumer unit quotation includes:

• A metal consumer unit.
• Individual Type A RCBO protection for each circuit.
• Type 2 surge protection.
• Appropriate inspection and testing for the replacement work.
• Electrical certification for the completed work.
• Building Regulations notification where applicable.
• Clear circuit labelling and a completed circuit schedule.

The quotation does not assume that unrelated pre-existing defects are included. If assessment or testing identifies additional remedial work, it will be explained and priced before it is carried out.

Does an Older Consumer Unit Automatically Need Replacing?

No. An older consumer unit is not automatically unsafe or an automatic EICR failure because of its age alone. Its condition, protective devices, earthing and bonding, signs of damage or overheating, and suitability for the installation matter more than age by itself.

Why Entigen Does Not Quote Dual-RCD Boards as Standard

At Entigen, we quote consumer unit replacements using individual Type A RCBO protection and Type 2 surge protection as our standard specification. Individual RCBOs help prevent a fault on one circuit from unnecessarily disconnecting others. We do not quote dual-RCD or split-load boards as our standard replacement specification because shared RCD arrangements can disconnect several circuits when one fault occurs.

How to Compare Quotes Properly

Do not compare consumer unit quotes on the board price alone. Ask what brand and protective devices are being installed, whether RCBOs and surge protection are included, what testing is included, how faults are handled, and what certificates you will receive. A quote that looks cheaper may exclude important work or assume the existing installation is already perfect.

The published figures are guide prices because circuit count, access, supply arrangements and existing defects vary between properties. After assessing the installation, Entigen provides a fixed quotation and identifies any additional work that would be priced separately.
