EICR Failed Because the MET Is Missing? Main Earthing Terminal Explained (London Guide)

If your EICR report says “Missing Main Earthing Terminal (MET)”, you are not alone.
This is one of the most misunderstood and stressful EICR failures, especially for landlords and owners of older London properties.

People usually ask:

• Is this dangerous?

• Is my property illegal to rent now?

• How expensive is this to fix?

• Can it be sorted quickly?

This guide answers all of that, clearly and honestly, with real-world examples, practical explanations, and London-specific context.

What Is a Main Earthing Terminal (MET)? (Simple Explanation)

The Main Earthing Terminal (MET) is the central point where all earthing and bonding conductors connect together.

It typically connects:

• The main earthing conductor from the supply

• Protective bonding to gas and water

• Circuit protective conductors (CPCs)

• The earth bar of the consumer unit

In plain English:

👉 The MET is what allows electricity to safely escape into the ground if something goes wrong.

Without a proper MET:

• Fault currents may not clear

• Protective devices may not trip

• Metal parts can become live

That’s why earthing is a core safety principle, not a technical extra.

Why a Missing MET Causes an EICR Failure

During an Electrical Installation Condition Report (EICR), the electrician must verify that the earthing and bonding system is present, continuous, and effective.

If the MET is:

• Missing

• Not identifiable

• Poorly connected

• Incorrectly installed

The electrician cannot confirm the installation is safe.

Typical EICR coding:

• C2 – Potentially Dangerous (most common)

• Occasionally C1 if immediate danger exists

Once a C2 is recorded, the EICR becomes UNSATISFACTORY.

How Serious Is a Missing Main Earthing Terminal?

Let’s be direct:
This is a serious safety defect.

Why it matters in real life:

• Metal taps, radiators, or appliances can become live

• RCDs may not trip within required time

• Electric shock risk increases

• Fire risk increases during faults

This is not something councils, insurers, or managing agents ignore.

Is a Missing MET Common in London?

Yes. Extremely common.

London has:

• Victorian and Edwardian housing stock

• Converted flats

• Multiple historic rewires

• Old fuse boards replaced without full upgrades

We see missing METs most often in:

• Converted flats

• Older rental properties

• DIY-modified installations

• Partial consumer unit upgrades

Real London Case Study: Failed EICR Due to Missing MET

Property: 2-bedroom converted flat, North London
Client: Private landlord
Scenario: Tenant due to move in within 7 days

What the EICR found:

• New consumer unit installed previously

• Earth conductors present but not terminated to a defined MET

• Bonding connected incorrectly

• No verifiable earthing reference point

Result:

• C2: Missing Main Earthing Terminal

• EICR status: UNSATISFACTORY

Remedial work completed:

• Installed compliant MET

• Correctly terminated earthing and bonding

• Tested earth continuity

• Verified RCD disconnection times

Outcome:

• All C2s cleared

• Satisfactory EICR issued

• Landlord compliant within 48 hours

This is a very typical London scenario.

How Is a Missing MET Fixed?

The fix depends on the existing installation, but usually involves:

1. Installing a compliant Main Earthing Terminal

2. Correctly terminating all earthing conductors

3. Verifying main bonding to gas and water

4. Testing earth continuity

5. Confirming fault loop impedance

6. Testing RCD/RCBO operation

⚠️ This work must be completed by a qualified electrician.

How Much Does It Cost to Fix a Missing MET in London?

Typical cost ranges:

• Basic MET installation and termination: £120–£250

• Additional bonding upgrades (if required): £80–£200

Prices depend on:

• Access

• Condition of existing wiring

• Whether bonding needs upgrading

Is Missing MET Worse Than Missing Bonding?

Yes, and this is important.

Comparison:

• Missing bonding: limits safety but may still have an earthing reference

• Missing MET: no reliable earthing reference at all

A missing MET undermines the entire protective system.

This is why electricians take it very seriously.

Can I Rent My Property If the MET Is Missing?

No.

If your EICR is unsatisfactory due to a missing MET:

• The property is not compliant

• Remedial work is required

• Councils can enforce penalties

Who Is Responsible for Fixing a Missing MET?

Houses:

• The property owner / landlord is responsible

Flats:

• Usually the leaseholder, but sometimes shared responsibility

• Occasionally involves the freeholder if earthing is communal

This is why expert assessment matters.

How Long Does It Take to Fix?

In most London properties:

• Same-day or next-day remedial work

• Certificate update within 24–48 hours

Common Myths About Missing METs

“The electrics have always worked fine”

Safety failures don’t announce themselves.

“It passed years ago”

Standards change. EICRs assess against current safety requirements.

“It’s just paperwork”

It’s not. It’s a fundamental safety issue.

Frequently Asked Questions

Is missing MET always a C2?

Almost always. Severity depends on the installation.

Can an electrician issue a certificate without fixing it?

No. The EICR remains unsatisfactory.

Does insurance care?

Yes. Insurers expect compliance with safety regulations.

Can it be fixed without rewiring?

In most cases, yes.

Is it common in older London flats?

Very common.

Key Takeaways

• Missing MET = serious safety issue

• Almost always results in unsatisfactory EICR

• Common in older London properties

• Usually fast and affordable to fix

• Must be addressed before renting
