Guidance library
EICR Guidance and Blog
Start with the question in front of you, not the publication date. This curated London EICR library groups practical guidance by finding, audience and next step so landlords, homeowners and commercial dutyholders can reach a relevant explanation without searching an unfiltered archive.
What this curated guidance library is for
The hub brings together implemented, reviewed guidance routes that answer recurring questions about EICR findings, inspection planning and report outcomes. Each listing has a page-specific summary so you can judge whether it addresses your issue before opening it. The library is selective rather than chronological: an older durable explanation can be more useful than a newer article whose subject does not match your report. Further implemented guidance on the same topics is listed in those groups rather than left unlinked.
Only topic groups containing published entries are shown. We do not create empty taxonomies, thin tag archives or new category routes simply to make the library look larger. Individual articles remain responsible for their detailed subject, qualifications and sources; the hub helps you choose between them. If wording on your report differs from an article scenario, use the report wording and seek project-specific advice rather than assuming the article assigns a code.
Codes and findings: interpret the observation first
The findings group starts with the durable C1, C2, C3 and FI classification guide, then offers focused articles about C2 wording, RCDs, surge protection, AFDDs, high Ze, protective bonding and a bathroom shaver-socket scenario. These pages explain concepts and useful questions. They do not assign a universal classification from one missing device or one test value because outcomes depend on the installation, observed risk and report context.
Use the report-example guide if you need help locating the outcome, observations, limitations and schedules. It is an illustrative reading aid, not a customer certificate and not evidence that another report is authentic. Where a finding may present immediate or potential danger, follow the report and competent electrical advice rather than waiting for a blog article to settle a site-specific technical decision.
Landlord and homeowner guidance answer different questions
Landlord guidance covers issues such as an unsatisfactory outcome, documented attempts to obtain tenant access and the context for short-term lets. Legal duties vary with jurisdiction, tenure, property and facts, so these articles use qualified language and direct readers towards current official guidance where appropriate. They provide general information, not legal advice, and do not replace the landlord’s compliance records or advice about a particular tenancy.
Homeowner guidance focuses on condition evidence, renewal planning and who may carry out an EICR without importing private-rental rules into every owner-occupied home. The validity guide is the starting point when somebody asks whether an existing report is still useful. It separates legal requirements, the report’s recommendation and requests from buyers, lenders, insurers or managing agents instead of claiming one universal life for every certificate.
Process, preparation and report outcomes
Process articles help before and after the site visit. The appointment-duration guide explains why property size, circuit count, records, access and defects can affect time on site; it is not a validity article. The cost page owns residential pricing and the separation between standard domestic booking and scoped commercial quotations. Reading those pages before arranging access can reduce avoidable uncertainty without promising an exact duration or outcome.
After inspection, begin with the report’s overall assessment and coded observations. The unsatisfactory landlord guide explains the relationship between the outcome, remedial work, further investigation and records. The remedial-work page describes the service pathway for addressing findings. A new booking is not a substitute for making urgent danger safe, and remedial work should respond to the actual observation rather than a generic list attached to a code.
Technical explainers without one-fact verdicts
Technical articles translate common report language into practical questions. High Ze concerns external earth fault loop impedance and requires the measured result, earthing arrangement and supply context to be understood. Missing protective bonding calls for confirmation of the services present and how protection is arranged. RCD, SPD and AFDD articles distinguish absence of a feature from an automatic fail in every existing installation.
The same discipline applies to the 230V shaver-socket scenario and C2 observations: an online title is not enough to classify a real installation. Use these guides to understand terminology, gather the relevant section of your report and have a focused conversation with the inspector or another competent person. Do not use them to erase limitations, downgrade observations remotely or authorise work without a suitable assessment.
Property use changes the route and the advice
A private rented flat, owner-occupied house, short-term let, shop and multi-board commercial site can raise different legal, operational and technical questions. The topic groups keep those contexts visible. Short-term-let guidance explores why the label alone does not settle the applicable regime. Commercial guidance highlights scoping, distribution complexity, access windows and operational risk rather than applying a residential bedroom calculator to business premises.
If a property has changed use, occupancy or electrical configuration since the last report, read the validity guide and audience-specific service page together. Guidance can identify information to gather, but the booking or quotation route must still capture the real property. Mixed-use and unusual premises should be described fully so the proposed scope does not omit shared supplies, communal areas or specialist equipment.
Featured high-value starting points
For a code on an existing report, start with “EICR C1, C2, C3 and FI codes explained”. For a C2 specifically, continue to the dedicated C2 article. For a date or renewal question, open “EICR validity and renewal in London”. For the time needed on site, use “How long does an EICR take in London?”—duration and validity are deliberately separate.
Landlords with an unsatisfactory result should use the unsatisfactory outcome guide; readers assessing protective measures can choose the relevant RCD, AFDD, bonding or shaver-socket article. Commercial readers should begin with the commercial EICR service guide because scope and quotation information shape the inspection. These featured routes are starting points, not a ranking of every article or a substitute for reading the report.
- Classification guide for C1, C2, C3 and FI observations
- Validity and renewal guide for context-dependent timing
- Unsatisfactory EICR guidance for landlord next steps
- Duration guide for access, preparation and time on site
- Commercial guide for business-premises scope and quotations
Find the right service when you are ready
Use these articles to understand an observation, prepare the property or decide what to ask about an existing report. When you are ready to arrange an inspection, the EICR services page helps you choose the route that fits your home, rental property or business.
The landlord, homeowner and commercial guides explain what to arrange and the information we need. For a residential price, use the certificate-cost page or calculator. You can also contact the team with your address and previous report if you are unsure which service to request.
Know when to read and when to book
Read first when you are trying to understand a code, decide which records matter, distinguish validity from appointment duration, or prepare questions about an existing result. Book when the need for a domestic inspection is clear and the property fits the residential route. Request a commercial quotation when premises, distribution or operating constraints require scoping. If there are signs of immediate electrical danger, seek prompt competent assistance rather than treating the hub or a routine booking slot as an emergency service.
Guidance cannot predict that an installation will be satisfactory or quote remedial work before relevant defects are known. Equally, booking does not require you to master every technical article. Provide accurate property details, the previous report where available and information about access or alterations; the inspection process can then address the actual installation.
A practical way to use the hub
First, identify whether your question concerns a finding, a legal or audience context, the inspection process, an outcome, a technical protective measure or property use. Second, read the entry summary and choose the narrowest relevant article. Third, compare the article with the exact wording, measurements and limitations on your report. Finally, follow the appropriate next route: ask the issuing inspector a focused question, obtain legal or contractual advice where needed, arrange remedial assessment, book a residential EICR or request a commercial quotation.
Return to the broader classification guide if a focused article assumes terminology you do not recognise. Use the validity guide when a timing question is being confused with report authenticity or appointment length. This keeps general education in its proper place: useful for understanding and preparation, but subordinate to property evidence, current official requirements and competent site-specific judgement.
Move from guidance to the appropriate next step
If you know that a residential inspection is needed, use the book EICR route. If you manage a business, mixed-use building or complex installation, open the commercial quotation pathway with enough information for scoping. For price structure, use the EICR certificate cost page. Otherwise, choose the topic group matching your question and keep the report available while you read.
