The electrician has fitted your new shower circuit. They may have replaced the consumer unit or wired a Swansea garden office.
The invoice may arrive without the paperwork you expected. You may wonder if the job is complete. You may also need proof for an insurer, buyer, letting agent, or landlord file.
What certificates should an electrician provide? You should receive an Installation Certificate (EIC) for new installations or new circuits. You should receive a Minor Works Certificate for eligible small changes. You should receive an EICR after an inspection. Some notifiable work in Wales may also lead to a Building Regulations Compliance Certificate. The document must match the work, not the invoice. Keep it with your property records.
Match the work to the certificate you need
The certificate must fit the electrical work. It does not depend on the size of the invoice.
A new shower, cooker, garden office, or consumer unit circuit normally needs an EIC. A condition inspection produces an EICR.
| Work at the property | Document to receive | When to request it | Possible extra paperwork |
|---|
| Full rewire, new installation or new circuit | EIC with test schedules | At completion, before final payment | Welsh Building Regulations route may apply |
| Eligible addition or alteration to an existing circuit | Minor Works Certificate | At completion | Depends on scope and current Welsh rules |
| Inspection for a sale, tenancy or safety check | EICR | When the report is issued | No installation certificate is created by inspection alone |
| Like-for-like accessory replacement without wiring changes | Usually invoice and work record | At completion | Certificate may not be required |
New circuits need an EIC
An EIC records initial verification. This means the electrician tested new work before putting it into service.
It should cover a consumer unit replacement, a rewire, or a new circuit from the consumer unit. Think of it like a car's first safety check.
BS 7671 sets the testing and certification rules. It is often called the IET Wiring Regulations.
Minor work may need a smaller certificate
A Minor Works Certificate can suit an eligible change to an existing circuit. Examples include adding a socket spur or changing part of a circuit.
It must not cover work that creates a new circuit. It also cannot cover work needing full initial verification.
The most frequent mistake is assuming every electrical job needs an EIC. Small work can still need proper testing.
Inspections produce an EICR
An EICR reports the condition of existing wiring on the inspection day. It helps landlords, buyers, insurers, and owners of older Swansea homes.
An EICR does not replace an EIC for recent installation work. Inspection alone does not certify new work.
Check registration before you book the job
Check a contractor's scheme registration before work starts. Membership is not the customer's certificate.
A register check helps confirm who you are hiring. It does not prove that your specific work was tested.
Check the live scheme register
Check the business on the current NICEIC contractor register. You can also check the relevant NAPIT register.
Match the business name to the quote and invoice. Match the telephone number and work category too.
A valid scheme listing is useful evidence. Keep a copy of the search result if needed.
Agree the paperwork in writing
Ask which certificate the electrician will issue before work begins. Ask who will sign it and when it will arrive.
Ask if the job needs notification under Building Regulations 2010 (Wales). Ask if the contractor will self-certify or use Building Control.
Written agreement avoids arguments after the work ends. It also makes the final payment discussion much clearer.
Check every page before making final payment
A valid EIC, Minor Works Certificate, or EICR should name the Swansea property. It should describe the work or inspection.
It should show dates, signatures, and relevant test data. Future electricians need this information to identify tested circuits.
Before final payment, check:- The full property address and a description matching the agreed work.
- Completion or inspection dates, certificate number and responsible signatures.
- Electrical test results and attached schedules of inspections and test results where relevant.
- Recorded EICR observations, circuit details, and the electrician or business registration details.
- Any Building Regulations notification reference or expected compliance document.
Match the address and scope
Check that the address includes the correct flat, house, or unit number. A certificate for another property cannot support your records.
Compare the work description with the quote and invoice. A new circuit should not appear as a vague "electrical works" entry.
One common case involves a garden office. The invoice says "supply fitted", but the EIC must identify the new circuit.
Read the tests and observations
Read the test pages, even if the figures look unfamiliar. They show that the electrician tested the circuits.
An EICR may record C1 for immediate danger. It may record C2 for a potentially dangerous issue needing urgent repair.
C3 means improvement is recommended. FI means further investigation is needed.
C1, C2, or FI normally means an unsatisfactory report. The issue needs repair or investigation first.
Welsh notification is separate from testing
An EIC proves electrical work was inspected and tested under BS 7671. Building Regulations paperwork records the right approval or notification route.
One document does not replace the other. Think of them as an MOT record and vehicle registration.
From electrical work to your records
1. Define work
New circuit, alteration or inspection?
2. Test and certify
EIC, Minor Works or EICR
3. Check Welsh route
Scheme notification or Building Control
Keep the certificate, schedules, invoice and any compliance paperwork together.
Notification depends on the exact job
Some domestic electrical work may need notification. An eligible Competent Person Scheme member may notify it.
Building Control may handle the route instead. Consumer unit replacements and new circuits can raise notification questions.
Work in particular locations can also need checks. Confirm the current Welsh position before work starts.
Ask the contractor first. Where needed, contact the City and County of Swansea Council Building Control service.
Keep evidence until the property changes hands
A Swansea landlord or property manager should ask for the named certificate. Do this before releasing the final balance.
You may agree a reasonable retention while paperwork is being processed. Do not refuse payment for every small fitting change.
Match payment records to the documents that the work should create. This habit helps with sales, insurance, tenancy files, and fault checks.
This guidance is less relevant to non-electrical work. It is also less relevant to like-for-like replacements that do not alter wiring. Large commercial, industrial, fire-alarm, emergency-lighting, and specialist systems may need extra sector certificates. These jobs need a specialist competent contractor.
Electrical certification and Building Regulations do not follow one identical UK-wide process. England commonly links domestic electrical work with Part P.
Work in Wales must follow Welsh Building Regulations. It must also follow local notification arrangements.
An EIC is sometimes called a new circuit certificate. Some people also call it a full rewire certificate.
It records testing and initial verification. It is not automatically Building Regulations evidence.
Likewise, an Electrical Installation Condition Report records the condition of existing wiring. It does not certify new work.
Confirm the route for the country where the property stands. Keep certificates, schedules, invoices, and compliance notices together.
For most Swansea homes, ask for the named certificate before booking. Then check it before final payment. A minor like-for-like fitting may only need an invoice, but new circuits need fuller evidence. This approach avoids both common errors. You will not demand unnecessary paperwork. You will also not accept missing proof for work that needs it.
Your questions answered
Should my electrician give a certificate?
Yes, when the work needs one. An EIC usually follows new circuits or installations. A Minor Works Certificate can cover eligible smaller changes. An EICR follows an inspection.
A very small like-for-like replacement may only need a clear invoice. It should also have a work record.
What electrical certificate types exist?
The main customer documents are an EIC, Minor Electrical Installation Works Certificate, and EICR. Some jobs also need Building Regulations compliance paperwork.
An EICR is an inspection report. It does not certify newly installed work.
Is an EICR enough after a rewire?
No, an EICR does not replace the EIC a rewire should receive. A new installation should also receive an EIC.
An EICR reports condition on its inspection date. It may be commissioned months or years after the work.
What do C1, C2 and C3 mean?
C1 means danger requiring immediate action. C2 means potentially dangerous and needing urgent remedial work.
C3 means improvement is recommended. FI means further investigation is needed before full assessment.
How long should a Welsh landlord keep an EICR?
Keep the EICR until a new report replaces it. Keep earlier reports with tenancy records where relevant.
Welsh rented properties generally need inspection and testing at least every 5 years. A report may state a shorter period.
What if my electrician will not send the certificate?
Ask in writing for the named document and certificate reference. Ask for notification confirmation within 7 days.
Keep the invoice and messages. Check NICEIC or NAPIT membership.
Use the scheme complaint route if the contractor does not resolve it. You can also contact Trading Standards.
Make the paperwork part of the booking
Book only after the quote states the work scope and certificate type. It should also state testing responsibility and the Welsh notification route.
Before paying the final balance, compare the document with the address and completed work. Check test schedules and signatures too.
Save every record in at least two places. A cloud folder and paper file work well.
