Electrical work done safely, with exact scope agreed before any tools open.
Cal Rowan installs modern consumer units with surge protection, EV home chargers, and carries out detailed EICR condition reports across Sheffield and the Hope Valley. Every job is quoted from photos and survey notes, never blind guesses.
Fifteen years wiring Victorian stone houses, modern timber frames, and rural Peak District workshops.
Calibrated digital multifunction installation tester connected with test leads at a wall socket
EV charging unit mounted on an external stone wall with neat conduit cable entry
An EV charger or consumer unit upgrade depends directly on earthing arrangements (TN-S, TN-C-S, TT) and main bonding to water and gas supplies. Reviewing photos of your board and meter first prevents unexpected variations on the day.
Every circuit is tested with calibrated multifunction instruments: insulation resistance, earth fault loop impedance, and RCD trip times. We classify defects strictly according to C1, C2, and C3 codes without scare tactics or manufactured upselling.
Protective floor runners are rolled out before tools are unpacked. All wall chasing and masonry drilling connects directly to M-class dust extraction vacuums to keep stone and plaster dust out of living rooms.
You upload a photo of your fuseboard with the outer lid closed, plus your incoming meter and supply fuse.
Cal calculates cable run lengths, earthing requirements, and specifies the exact components in a written quote.
Work proceeds using protective floor runners, tool extraction, and neat cable routing through floor voids.
Every circuit is tested with multifunction testers, and your digital compliance certificate is emailed within 24 hours.
Covering south and west Sheffield out along the A6187 corridor into Derbyshire:
Keep the hinged outer door closed and never unscrew any cover plates. Stand back about one metre in good lighting so the main switch, all circuit switches, and surrounding meter cables are visible in a single photo.
Typically between two and three hours. Power is isolated circuit-by-circuit for short testing intervals so freezers and heating systems are not disrupted.
The report will itemise any immediate hazards (Code C1) or potential dangers (Code C2). Cal explains each observation clearly with photographic evidence and provides a separate quote for remedial work without obligation.
We calculate maximum demand under diversity rules. If a supply fuse upgrade to 80A or 100A is needed, we liaise with Northern Powergrid on your behalf to request the free fuse upgrade before installation.
