"Mrs Davies, Chelsea London, consumer unit rewire, Part P notified, labour eight hours."
What electricians in London actually have to log on a job
- Part P notifications — Auto-flag notifiable jobs (consumer unit, kitchen, bathroom, outdoor) and attach the local-authority Part P certificate as a PDF.
- NICEIC / NAPIT / Stroma — Your scheme number is auto-prefixed on every invoice and Minor Works cert.
- EICR & Minor Works — Store the cert PDF inside the invoice thread; chase customer sign-off via WhatsApp.
- BS 7671 (18th Edition) line items — RCBO upgrades, SPDs, AFDDs each as their own line so the customer sees what they’re paying for.
- Calibration / test-equipment — Log MFT calibration date once a year; Holdfort reminds you 30 days before it lapses.
What electricians in London actually deal with
Thames Water (most of the capital) or Affinity Water (north-west outskirts)
ULEZ — every day, every postcode. If your van is non-compliant, that’s £12.50 per working day on top of fuel.
32 London boroughs plus the City — Building Control is handled borough-by-borough, and Part P notifications vary by borough route.
Victorian terraces, ex-council flats, Georgian conversions, modern new-builds around Docklands and Stratford. Old lead pipework still common in pre-1970 stock.
Serving Chelsea, Hackney, Clapham, Islington, Camden and the rest of Greater London. Parking restrictions (red routes, controlled parking zones, school streets) and the congestion charge zone make a 20-minute job a two-hour billing situation.
London callout rates run £75–£120 vs £45–£80 for the rest of the UK. Materials cost the same but travel time and congestion eat the margin. Holdfort doesn’t set your prices — your rates are yours — but it stops you from losing track of what’s owed, what’s paid, and what’s been expensed along the way. All through WhatsApp. No app to install, no portal to log into.
Questions from London electricians
Yes. Say "Part P notified" in the voice note and Holdfort tags the invoice with the building-control reference field, ready for you to drop in the local-authority cert PDF when it comes back.
Yes — send the cert as a WhatsApp file reply and Holdfort attaches it to the invoice thread. The customer gets one PDF with the invoice and the cert.
Not as a separate line, but you can log them as receipts (photo the email or Dart Charge notice) and they’re captured as deductible vehicle expenses at tax time. Every charged day reduces your tax bill.
Yes — set your scheme (NICEIC, NAPIT, ELECSA, Stroma) once. Each invoice prints the scheme and your notification reference, which is what boroughs like Southwark and Lambeth ask for on Building Control self-certification.
They voice-note the invoice from inside the van before moving. Sixty seconds, invoice sent, and they’re out of the red route before the warden comes. It’s the main reason central-London trades signed up first.
Yes — quarterly-ready breakdowns and sole-trader categories. Required for self-employed earners over the MTD threshold from April 2026. See the MTD guide.
