Buying a House? Check the Electrics Before You Commit

Mark Emery • 24 August 2026

The Hidden Risks Behind Your Biggest Purchase


Buying a house is likely to be one of the biggest financial commitments you will ever make.


You may spend time checking the local area, looking at schools, measuring rooms and deciding where the furniture will go. You will probably arrange a property survey and carefully review the mortgage paperwork.


But how much do you really know about the condition of the electrics?


Think about it another way. Would you buy a car without checking whether it had a valid MOT or knowing whether there were potentially expensive problems hiding beneath the surface?


Probably not.


Yet people regularly spend hundreds of thousands of pounds on a property without arranging for the electrical installation to be properly inspected and tested.


A standard property survey may comment on the visible condition of the electrics, but it will not normally include the detailed inspection and electrical testing carried out as part of an Electrical Installation Condition Report, commonly known as an EICR. Electrical Safety First therefore advises buyers to request a recent EICR or arrange one through a registered electrician. (Electrical Safety First)



What is an EICR?


An EICR is a detailed assessment of the fixed electrical installation within a property.


It helps establish whether the installation is in a satisfactory condition for continued use and identifies damage, deterioration, defects or potentially dangerous conditions that may need attention. (Electrical Safety First)


The inspection covers the fixed electrical system rather than portable appliances. This can include:

  • The consumer unit, sometimes still called the fuse box
  • Fixed wiring and electrical circuits
  • Sockets and switches
  • Lighting circuits
  • Earthing and bonding arrangements
  • Protective devices, including RCD protection
  • Signs of damage, deterioration or overheating
  • Alterations or additions that may not have been installed correctly
  • Potential electric shock or fire risks
  • The suitability of the installation for continued use

Electrical testing is also carried out to assess matters such as the integrity of the wiring, the effectiveness of protective measures and whether circuits disconnect safely when a fault occurs.

Once the inspection has been completed, you will receive a report setting out the findings, any observations recorded and their classification codes.


EICR report


Why is this particularly important when buying an older property?


Older does not automatically mean unsafe.


There are plenty of older homes with well-maintained electrical installations. Equally, there are newer properties where alterations have been made poorly or without the correct certification.


However, an older property may have had decades of additions and changes.


Extra sockets may have been installed. Kitchens may have been replaced. Extensions, loft conversions or garden buildings may have been added. Different owners may have carried out work at different times, and the paperwork may no longer be available.


What looks fine from the outside does not necessarily tell you what is happening behind the sockets, under the floors or inside the consumer unit.


An EICR can help uncover issues such as ageing wiring, inadequate earthing, damaged accessories, insufficient protection or poorly executed alterations. It may also indicate whether further investigation or remedial work is required.


Avoid an expensive surprise after moving in


When you are buying a house, your budget is rarely limited to the purchase price.

There are legal fees, mortgage costs, surveys, removals, decorating and all the other expenses that come with making a new property your home.


Discovering after completion that the consumer unit needs upgrading, circuits require remedial work or the property may need significant rewiring can be an unwelcome and potentially costly surprise.


An EICR gives you more information before you commit.

Depending on the findings and the stage of the purchase, it may allow you to:


  • Ask the seller for further information or electrical certificates
  • Obtain quotations for any recommended work
  • Factor those costs into your moving budget
  • Discuss significant findings with your surveyor or solicitor
  • Plan which work should be completed before you move in
  • Make a more informed decision about the property


An EICR should not be treated simply as a way to renegotiate a purchase price. Its real value is helping you understand what you are buying and what may need attention.


Plan for the home you want to create


An EICR is not only about identifying immediate safety concerns. It can also be a useful starting point for your future plans.


The electrical demands placed on modern homes are very different from those of previous generations.


You may be planning to install:


  • An electric vehicle charger
  • Air conditioning
  • An electric shower
  • An induction hob
  • Garden lighting and outdoor sockets
  • A hot tub
  • Solar panels or battery storage
  • A home office
  • Additional kitchen appliances
  • An extension or loft conversion


These additions may require new circuits, additional protection or changes to the consumer unit. In some cases, the existing installation may need remedial work or upgrading before the new equipment can be added safely.


For example, a consumer unit that is operating adequately for the property’s current needs may have limited capacity for additional circuits. NICEIC notes that householders adding appliances or extending a property may need a consumer unit with sufficient space for those additions. (NICEIC)


Having the installation assessed gives you a clearer picture of where you stand.


It means that instead of deciding six months after moving in that you want an EV charger, only to discover that other electrical work is required first, you can start planning and budgeting from the beginning.


Does a satisfactory EICR mean the installation is brand new?


No.


This is an important point.


An EICR assesses whether the electrical installation is in a satisfactory condition for continued use. It does not mean that every part of the installation meets the very latest specification, nor does it mean that nothing will ever require maintenance or replacement.


Electrical installations naturally age, and future faults can still occur.


The report provides a professional assessment based on the parts of the installation that can be accessed, inspected and tested at the time. Any agreed limitations should be recorded on the report.


It is therefore better viewed as an electrical health check rather than a guarantee.



What do the EICR codes mean?


Where an issue is identified, it may be given a classification code.


The main codes you may see are:


  • C1: Danger present
    There is an immediate risk, and urgent action is required to make the installation safe.


  • C2: Potentially dangerous
    The issue may not present an immediate danger at that moment, but urgent remedial action is required.


  • C3: Improvement recommended
    The installation may not meet the latest standards in a particular area, but the observation is not considered immediately or potentially dangerous.


  • FI: Further investigation required
    The inspector has identified something that cannot be fully assessed within the inspection and requires further investigation without delay.


A report containing a C1, C2 or FI observation will generally be assessed as unsatisfactory and will require action. The electrician should explain the findings clearly so that you understand what needs to be addressed and why.



Is an EICR legally required when buying a house?


For an owner-occupied property, there is generally no legal requirement for the seller to provide an EICR before selling.


That does not mean it is not worth having one.


Electrical Safety First recommends asking whether the electrics have been fully checked within the previous ten years and requesting a copy of the report. When no recent report is available, buyers are advised to arrange an EICR through a registered electrician. (Electrical Safety First)


The important question is not simply, “Do I legally have to arrange one?”


It is:


“Do I want to understand the condition of the electrical installation before I buy the property?”

When you consider how much you are investing, arranging an electrical inspection can be a sensible part of your overall due diligence.



When should you arrange the EICR?


Ideally, the EICR should be arranged before contracts are exchanged and while there is still time to understand the findings.


You will need the seller’s permission, and access will be required to the property, consumer unit, sockets and other parts of the electrical installation.


Testing may require the electricity to be turned off temporarily. Some items may also need to be unplugged or moved to provide access.


The electrician should discuss the likely duration, access requirements and any limitations before the inspection takes place.



Do not rely on appearances alone


Fresh paint, a modern kitchen and attractive lighting can make a property feel ready to move into.


However, new sockets or decorative fittings do not necessarily mean the whole electrical installation has been upgraded.


Similarly, an older-looking consumer unit does not automatically mean that a property requires a complete rewire.


The condition of an electrical installation cannot be judged accurately from photographs or a quick walk around. It requires proper inspection and testing by someone with the relevant skills and experience.


Buy with your eyes open


An EICR may not be the most exciting part of buying a home, but it could be one of the most useful.

It can help you:


  • Understand the condition of the fixed electrical installation
  • Identify safety concerns before moving in
  • Avoid unexpected costs
  • Prioritise any remedial work
  • Budget more accurately
  • Plan future improvements
  • Make a better-informed buying decision


You would not knowingly buy a car without understanding whether it was safe and roadworthy.


When you are investing considerably more in a property, it makes sense to understand the condition of the electrics too.
