If you own or manage a Swansea property, checks should suit its use, age and recent changes. A visual check can spot clear damage. Only a qualified electrician can assess fixed-wiring safety through an Electrical Installation Condition Report (EICR).
How often should you have your home electrical wiring inspected? Most owner-occupied homes need a formal inspection every 10 years. Rental properties in England need an EICR every 5 years. Older wiring, a property purchase, renovation, tenant change, tripping circuits, scorch marks or shocks may mean you need one sooner.
When your home needs an EICR sooner
Owners: 10 years, unless something changes
Owner-occupied homes normally need a formal fixed-wiring inspection at least every 10 years. That timing assumes the installation has no known faults or major changes.
Book sooner after major electrical work, flood damage, a house purchase or missing paperwork. These events can change what the electrician needs to check.
A 10-year date is not a promise that every circuit will stay safe. It is a planned check, like an MOT for the fixed electrical system.
Landlords: five years is a legal minimum
In England, the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 require landlords to inspect and test fixed electrics. The gap between tests must not exceed five years.
The report may set an earlier date. That earlier date then takes priority.
Swansea is in Wales, not England. Welsh rented homes have their own rules under Renting Homes legislation. A five-year cycle is also the practical requirement there. Landlords and agents should check the current duty for their tenancy. Do not copy an English template without checking.
For a normal home, plan for 10 years if you own it. Plan for 5 years if you let it. Bring the date forward after major work, a sale, purchase, water damage, missing paperwork, heat, damage or repeated tripping.
A simple timing guide: arrange an inspection now when you buy a property without recent paperwork. Also book one before major alterations or after taking over an older home. Faults also justify a prompt visit.
A typical owner-occupied property with a satisfactory EICR normally needs testing every 10 years. A rental property needs an EICR on the legal cycle. This is commonly every five years in England and Wales. The report may require an earlier test.
A change of tenant does not automatically cancel a valid report. Landlords must give the incoming occupier the required report information. Book testing early when the current certificate nears expiry.
EICR, PAT or rewire: choose the right job
A visual check cannot test hidden wiring
A visual check looks for damage you can see. It cannot test cables behind walls, beneath floors or inside the consumer unit.
An EICR tests the fixed installation. This includes circuits, sockets, lights, earthing, bonding and protective devices.
The most common mistake is treating a tidy consumer unit as proof of safety. Hidden faults can still exist in older cables or connections.
PAT tests appliances, not house circuits
Portable Appliance Testing, usually called PAT, covers movable items. These include extension leads, kettles, office equipment and landlord-supplied appliances.
PAT does not inspect fixed sockets, lighting circuits or the consumer unit. Think of it as checking a toaster, not the kitchen wiring.
| Service | What it covers | Typical trigger | Indicative cost |
|---|
| Visual check | Visible accessories and damage | Between formal checks | Often part of a visit |
| EICR | Fixed wiring and protection | 10 years, 5 years rental, or earlier | About £150 to £350+ |
| PAT | Plug-in appliances | Supplied portable items | Priced per item or visit |
| Rewire | Replacement cables and fittings | Failed or unsuitable installation | Usually £4,000+ for smaller homes |

Our recommendation
A UK socket tester can spot a clearly wrong socket reading between visits. It cannot replace an EICR. It cannot prove every circuit is safe.
- Shows common live, neutral and earth wiring faults at a standard UK socket
- Helps identify one socket worth reporting to a registered electrician
- Provides a quick check after a socket faceplate has been replaced

A socket tester can flag one obvious issue. The next section explains when you need much faster action.
Old wiring and warning signs need faster action
Frequent circuit-breaker trips need prompt fault finding. A burning smell, buzzing, hot sockets, flickering lights, shocks, scorch marks or damaged cable also need attention.
Switch off the affected circuit if it is safe. Do not keep resetting it to hide the problem.
An EICR can record C1, C2 and FI observations. C1 means danger is present. C2 means potentially dangerous work needs action. FI means further investigation is needed. Any of these results is unsatisfactory.
Do not wait for the general interval if you smell burning or find hot outlets. Act now if you see damage, receive shocks or notice flickering lights. Repeated RCD or consumer-unit trips also need prompt attention. Industrial sites, high-risk premises and properties with contract terms need a different schedule.
Age alone does not prove that a property needs rewiring. For wiring over 25 years old, a qualified electrician should assess cables, earthing and bonding. They should also check socket circuits, lighting circuits, protective devices, the consumer unit and test results.
A sound installation may need only an EICR and targeted maintenance. Missing RCD protection, old fuse boards or poor cable insulation may support partial upgrades. Too few circuits or repeated tripping can also support upgrades.
Full rewiring is usually for unsafe or badly worn installations. It may also suit a home that cannot support its intended use. Get a separate quote for rewiring, inspection and smaller repairs.
Old wiring needs evidence, not guesswork. The report details below show how to turn that evidence into action.
Prepare for testing and avoid costly delays
Give safe access to every key point
Give the electrician safe access to sockets, lights and the consumer unit. Move furniture where needed before the visit.
Tell the electrician about hidden cables, recent work and known faults. Clear information can prevent missed tests and return visits.
Access can affect how long an EICR takes. A small flat often takes between 2 and 4 hours.
Check the report before accepting a quote
Check the electrician's registration with NICEIC, NAPIT or another recognised competent-person scheme. Ask how many circuits the quote covers.
Building Regulations Part P can apply to some domestic work in England and Wales. Ask who will make any required notification.
A clean result does not mean the house needs no care for another decade. It means the tested installation was satisfactory on that date. Keep the report and bring the next date forward after property changes.
After an unsatisfactory EICR, ask for each observation in clear terms. Ask which circuit it affects, its risk level and what work is needed.
C1 observations need immediate action because danger is present. C2 items need prompt correction because they are potentially dangerous. FI observations need further investigation before anyone can confirm safety.
A contractor may make an immediate hazard safe during the visit. Repairs do not automatically change the original EICR into a satisfactory certificate.
Keep invoices, certificates and proof of remedial work. Get written evidence that the relevant observations have been resolved. Landlord report sharing and repair deadlines can be legal duties.
Good records make the next decision much easier.
What people ask
How often should electrics be tested in a rented home?
Rented homes in England need an EICR at least every 5 years. Test sooner if the existing report gives an earlier date. Welsh landlords should follow Welsh renting rules. These also require regular electrical inspection and testing.
What does an electrical safety check involve in a home?
An EICR checks fixed wiring, sockets, lights, protective devices, earthing and bonding. It includes tests and coded observations. A visual check or PAT test does not do this.
How long does an electrical safety check take in a small flat?
An EICR in a small flat often takes between 2 and 4 hours. Access, circuit numbers and faults can extend the visit.
Does a 25-year-old house need rewiring?
A 25-year-old installation does not automatically need rewiring. An EICR shows whether maintenance, partial upgrades or full replacement is the sensible next step.
Choose the next electrical check with confidence
The essentials: owner-occupied homes normally need a formal check every 10 years. / Private rentals need an EICR at least every 5 years, subject to England or Wales rules. / PAT does not test fixed wiring. / Warning signs, major work and unclear history justify inspection now, not at the next calendar date.
For a Swansea home, first identify the job you need. It may be an EICR, a fault visit or an old-wiring assessment.
Then compare registered electricians by circuit allowance, report scope and repair prices. Do not choose only the lowest inspection quote.
