EICR, EIC or Minor Works Certificate: which one do you need?

Three documents that are often confused, what each is for, and which one proves remedial work is done.

Sources checked · Applies to England

In short: an EICR reports on the condition of an existing installation. An Electrical Installation Certificate (EIC) certifies new work such as a new circuit or consumer unit. A Minor Works Certificate certifies smaller alterations that don't add a circuit.
DocumentWhat it's forTypical examples
EICRCondition of an existing installationLandlord inspections, buying a home, periodic checks
EICNew installation workRewire, new circuit, consumer unit replacement, EV charger on a new circuit
Minor Works CertificateSmall additions or alterations to an existing circuitExtra socket on a circuit, replacing a light fitting or accessory

All three are model forms in BS 7671, the UK wiring regulations (IET model forms).

An EICR isn't a certificate of new work

An EICR records what the inspector found on the day, within the agreed extent and limitations, using codes C1, C2, C3 and FI. It isn't a guarantee of future safety and can't certify work that someone else installed.

EIC: only for work you saw being done

An EIC is signed by the people responsible for the design, construction, and inspection and testing of the work. It can't honestly be issued afterwards for work that wasn't inspected and tested as it was installed. For that, an EICR describing its condition is the honest alternative.

Part P: when building control is involved (England)

In England, some domestic electrical work is notifiable under the Building Regulations: a new circuit, a consumer unit replacement, or work on circuits in a special location (near a bath, shower, pool or sauna) (regulation 12). Kitchens aren't special locations in England. A registered competent person can self-certify the work. You get a Building Regulations compliance certificate, and building control is notified within 30 days (Approved Document P).

Which do landlords need after remedial work?

GOV.UK says the written confirmation can be the certificate for the remedial work (an EIC or Minor Works Certificate) or a new satisfactory EICR. Send it to your tenants with the original report within 28 days of the work (GOV.UK guidance).
