Fault finding, consumer-unit upgrades, lighting, sockets and rewires across London and the M25, with a 24-hour emergency electrician when it can't wait.
Electrical work in UK domestic and commercial property is the regulated trade of installing, testing, repairing, and maintaining the fixed wiring, consumer units, sockets, lighting, and connected systems that bring mains electricity safely into the building. Most fixed electrical work is “notifiable” under Part P of the Building Regulations, and it must be carried out by a registered electrician (NICEIC, NAPIT, or equivalent) and certificated. The job categories split between reactive work (faults, breakdowns, emergency call-outs) and planned upgrades (rewires, consumer-unit replacements, EV charger installs).
Call when: a circuit keeps tripping; you smell burning near a socket; lights flicker or dim; you are adding sockets or upgrading the consumer unit; or you are installing an EV charger or whole-home smart system.
Six categories cover almost every electrical call.
Adding new sockets, replacing damaged or scorched sockets, and diagnostic visits for circuits that keep tripping or appliances that lose power intermittently. We test the circuit, find the fault, and fix it, not just swap the nearest part.
Replacement of the fuse box (consumer unit) to current 18th Edition standards with RCD protection on every circuit. A typical job takes around 4–6 hours, depending on circuit count. Notifiable work; we issue the Part P certificate on completion.
Whole-property rewires for older buildings (typically 1970s and earlier with rubber-insulated cabling) and partial rewires for kitchen and bathroom refurbishment work. Most full rewires take 5–10 working days depending on property size and access.
Fitting new light fixtures, downlights, and pendant lighting, switch replacements, and repairs to lighting circuits that have stopped working properly.
Smart thermostats (Hive, Nest, Tado), smart lighting (Lutron, Hue), video doorbells, automated blinds, and home-charging EV chargers for domestic plug-in vehicles. We handle the wiring run, supply protection, and any consumer-unit work needed.
24-hour rapid response for tripped circuits, exposed wiring, power outages, sparking sockets, and burning smells. 1–2 hour response across London and the M25.
More on emergency electricianFour outcomes that separate us from the average electrician search result.
Every job that legally needs certification gets one. We issue Part P certificates on the day for notifiable work, so there is no waiting weeks for paperwork.
Extra socket, new light fitting, or consumer-unit upgrade: every job is quoted and agreed with you in writing before we pick up a screwdriver.
Cheaper electricians swap parts until something works and bill you regardless. We diagnose first, usually 15–30 minutes of testing, so you only pay for the fix that actually solves the problem.
12-month workmanship guarantee in writing on every electrical job. Public liability insured. If the same fault returns inside the warranty window we come back at our cost.
The same five-step process every electrical call follows.
Phone 020 8068 2295, email, or send photos. Describe the symptoms (which circuit, what trips it, when it started). We can often quote on the call for defined jobs.
For unclear faults, the electrician runs a full diagnostic visit: circuit tests, insulation tests, RCD trip tests. Free for paid repair work.
Written quote covering labour, parts, certification, and disposal. Materials itemised separately. The scope you accept is what we deliver.
Most domestic electrical jobs complete in a single visit. Larger jobs (rewires, consumer-unit upgrades) get a confirmed schedule before we arrive.
Part P certificate issued on notifiable work. 12-month workmanship guarantee in writing.
According to Electrical Safety First, an estimated 1 in 6 UK fire-service callouts to dwelling fires has an electrical cause, and the majority of those originate in old or poorly-installed fixed wiring. Working with a qualified, registered electrician is not a marketing line; under Part P of the Building Regulations it is the legal requirement for most fixed work in domestic property.
Every electrician on our team is fully qualified and Part P compliant. We carry public liability cover, issue Part P certificates on every notifiable job, and are rated highly by our customers on Google and Checkatrade.
ARI Maintenance is led by Arianne ‘Ari’ Raofi, founder, who built the company in March 2025 to give London property owners one accountable team for every trade. Ari signs off on all major electrical work (full rewires, commercial installs, multi-property landlord contracts). Day-to-day electrical work is carried out by named, qualified Part P-registered electricians.
“The electrical jobs we get called to most aren’t the emergencies. They’re the ones where another electrician has already been out, given a vague verbal quote for a full rewire, when the property really needed a partial one or just a consumer unit upgrade. Half the work is figuring out exactly what the property needs and being straight about it, not defaulting to the biggest job.”
Every electrical job gets a written quote before any work starts, so you know exactly what is being done and when.
Materials are itemised separately on every quote, and nothing is added to the job without agreeing it with you first.
