Buying a house is one of the biggest investments you’ll make. While most buyers focus on the survey, roof condition, and damp, the electrics are often overlooked until after completion. That can be a costly mistake. Here’s what you should check before signing on the dotted line.

Why Electrics Matter When Buying a Property

Faulty or outdated wiring is one of the most expensive problems to fix in a home. A full house rewiringe can take over a week and requires significant disruption — lifting floors, chasing walls, and redecorating afterwards. If the property you’re buying needs a rewire, that’s a significant additional cost on top of the purchase price. Knowing about it before you buy gives you negotiating power.

Warning Signs to Look For During Viewings

You don’t need to be an electrician to spot potential problems. During property viewings, look for old round-pin sockets (these indicate wiring from the 1950s or earlier), a dated fuse box without modern RCD protection, brown or discoloured sockets or switches, cables running along skirting boards rather than being concealed in walls, and any visible damage to sockets or light switches. If you notice any of these signs, it’s worth getting a professional inspection before making an offer.

Should You Get an EICR Before Buying?

An EICR (Electrical Installation Condition Report) is the gold standard for assessing a property’s electrical safety. It’s not a legal requirement when buying a home, but it’s strongly recommended — especially for older properties. An EICR will tell you the exact condition of the wiring, whether any circuits are overloaded or unsafe, if the consumer unit meets current standards, and whether any remedial work is needed. The report grades issues from C1 (danger present — requires immediate attention) to C3 (improvement recommended). If a property comes back with C1 or C2 codes, you’ll want to factor the repair costs into your offer or ask the seller to fix them before completion.

What About the Seller’s Electrical Certificate?

Sellers aren’t legally required to provide electrical certificates in England, though landlords must have a valid EICR for rental properties. If the seller has recent certificates (an Electrical Installation Certificate from a rewire or a previous EICR), ask to see them. If they can’t produce any certificates, that’s another reason to arrange your own inspection.

When to Walk Away

Not every electrical issue is a deal-breaker. A property that needs a consumer unit upgrade is a manageable cost. But a full rewire on top of a stretched purchase budget could leave you in difficulty. The key is knowing what you’re getting into. An EICR before exchange gives you the full picture and puts you in control of the decision.
