AI Tools Built for UK Electricians

The Circuit Designer is the most technically advanced of the eight specialists. It takes a plain-English description of an installation and produces a complete electrical design that you can take straight to site. Describe a property — "four-bedroom detached house, electric vehicle charger in the garage, 10.8kW electric shower, induction hob, gas boiler, combination of LED downlights and pendant lights throughout" — and the AI generates a full consumer unit schedule, circuit-by-circuit.

For each circuit, the designer specifies the protective device type and rating (MCB or RCBO, with the correct type — Type B for resistive loads, Type C for small motor loads, Type D for large inductive loads), the cable type and size calculated using the BS 7671 Appendix 4 cable tables with an adiabatic check (Reg 543.1.3), the maximum Zs value for the chosen protective device rating, and whether additional RCD protection is required under Regulation 411.3.2. The calculations account for all correction factors: ambient temperature (Ca), grouping (Cg), thermal insulation (Ci), and the semi-enclosed fuse factor (Cc) where applicable.

The designer also handles the newer requirements of BS 7671. For EV charger circuits, it specifies Type A RCD protection (or Type B where required by the charger manufacturer), applies the correct cable sizing for continuous load (the charger draws its full rated current for extended periods, so the cable must be rated for 100% of the load current without derating), and ensures the cable route from the consumer unit to the garage accounts for any derating due to thermal insulation in walls or lofts. For electric shower circuits, it checks whether the incoming supply can handle the additional load and recommends a main switch upgrade or supply application if necessary.

What makes this tool genuinely useful on the job is that it explains its reasoning. If you ask why it chose a 6mm cable instead of 4mm for a particular circuit, it walks you through the calculation step by step, citing the specific BS 7671 tables used at each stage. This is not a black box — it is a design assistant that shows its working, so you can verify every decision and take professional responsibility for the final design with confidence.

Quoting is the part of the job most electricians dread. Underquote and you lose money. Overquote and you lose the job. The Cost Engineer removes the guesswork by combining live trade pricing data with real-world labour timing benchmarks to produce accurate, professional quotes in minutes.

The system works on a simple principle: you describe the job in plain English. "Consumer unit change in a 1970s three-bed semi, existing rewireable fuses, 8 circuits, supply is TN-C-S, meter in the hallway cupboard." The Cost Engineer breaks the job down into materials and labour. For materials, it generates a full bill of quantities with actual product names and trade prices from major UK wholesalers — not list prices, but the prices you actually pay with a trade account. For labour, it uses timing data from thousands of completed jobs to estimate how long each task takes: isolating the existing supply, removing the old board, installing the new consumer unit, connecting circuits, testing and commissioning, and completing the paperwork.

The Cost Engineer also handles the business side. You set your labour rate, overhead percentage, and target profit margin. The AI applies these to produce a final price with a clear breakdown you can present to the customer. If the customer queries a specific line item, you can explain exactly what it covers. The system also generates a professional quote document with your company details, a description of works, terms and conditions, and a validity period. Over time, the Cost Engineer learns from jobs you mark as completed, comparing estimates to actual costs and adjusting its models to match your working speed and local pricing.

The Installation Guide is built for electricians who want clear, step-by-step procedures for any type of electrical work. Whether you are installing a new lighting circuit, adding an EV charger, fitting a bathroom extractor fan on a timer, or wiring a three-phase distribution board, the guide walks you through every step from isolation to testing and commissioning.

Each guide starts with the prerequisites: the tools and materials you need, the regulations that apply to this specific type of work, and any notifications or certifications required (for example, Part P notification for a new circuit in a dwelling). It then provides a numbered sequence of steps, each with enough detail to follow without ambiguity. Steps reference specific BS 7671 regulations — for example, when wiring a bathroom circuit, the guide explains the zone requirements from Section 701, the IP ratings needed for equipment in each zone, and the requirement for supplementary bonding under Regulation 701.415.2 (unless all circuits are RCD-protected and the main bonding is verified).

The testing and commissioning section of each guide lists the specific tests required for that circuit type, in the correct order per GN3 (IET Guidance Note 3: Inspection and Testing). For a new circuit, this means continuity of protective conductors (R1+R2), continuity of ring final circuit conductors (for ring circuits), insulation resistance, polarity, earth fault loop impedance, prospective fault current, and RCD operation. The guide provides the expected values and pass/fail criteria for each test, so you know immediately whether the installation is compliant.

Apprentices find this tool particularly valuable because it bridges the gap between theory and practice. You learn the regulations in college, but the Installation Guide shows you how those regulations translate into physical actions on site. Qualified electricians use it for less common work — not everyone installs three-phase supplies or commercial kitchen extracts every week, and having a regulation-referenced step-by-step guide eliminates the risk of missing a requirement.

The Maintenance Agent helps you create and manage maintenance schedules for electrical installations. BS 7671 Section 341 requires that every installation is maintained to keep it in a safe condition, and the frequency of periodic inspection depends on the type of installation and its use. The Maintenance Agent knows the recommended maximum periodic inspection intervals from IET Guidance Note 3: five years for domestic premises, three years for commercial, one year for construction sites and swimming pools, and specific intervals for other installation types.

For commercial and industrial clients, the Maintenance Agent generates a complete maintenance programme covering periodic inspection and testing, thermographic surveys, RCD testing (the quarterly functional test by pressing the test button, plus the full instrument test at the periodic inspection interval), emergency lighting testing (monthly short-duration and annual three-hour discharge tests per BS 5266), and fire alarm testing (weekly call point tests and six-monthly full system tests per BS 5839). The agent produces a calendar of all required maintenance activities, sends reminders to both the electrician and the client, and tracks compliance status so nothing falls through the cracks.

The Health and Safety specialist is purpose-built for the documentation that electricians need on every job. In the real world, principal contractors, local authorities, and commercial clients increasingly require formal RAMS (Risk Assessment and Method Statement) documents before you are allowed on site. Writing these from scratch is tedious and time-consuming. Our Health and Safety AI generates complete, site-specific RAMS documents from a brief description of the work and the site conditions.

Describe the job — "second fix in a new-build primary school, working at height on scaffolding in the assembly hall, chasing walls for containment, dust and noise considerations, occupied adjacent classrooms" — and the AI produces a risk assessment covering every identified hazard with likelihood and severity ratings, control measures, residual risk scores, and responsible persons. The method statement provides a step-by-step procedure for the work, PPE requirements at each stage, permits required, emergency procedures, and environmental considerations. All documents reference current legislation including the Health and Safety at Work Act 1974, the Electricity at Work Regulations 1989, the Work at Height Regulations 2005, and the Construction (Design and Management) Regulations 2015.

The accuracy of any AI tool depends entirely on the quality of its training data. That is why we have invested heavily in building a comprehensive knowledge base that covers the full scope of the IET Wiring Regulations and supporting guidance documents.

The core training data includes BS 7671:2018+A4:2026, which is the current 18th Edition of the IET Wiring Regulations — the standard that governs every electrical installation in the United Kingdom. It also includes Amendment 4:2024 (A4:2026), issued on 31 July 2024, which adds Regulation 530.3.2 covering the requirements for bidirectional and unidirectional protective devices. This amendment is particularly relevant for installations with battery storage systems, solar PV, and other sources of reverse power flow, where standard unidirectional devices may not provide adequate protection.

Beyond the core regulations, the AI draws on the IET On-Site Guide, which provides simplified tables and procedures for common installation work; all eight IET Guidance Notes covering selection and erection, inspection and testing, protection against overcurrent, protection against fire, protection against electric shock, protection against electromagnetic disturbances, special installations and locations, and earthing and bonding; and a curated library of real-world installation case studies and worked examples.
