What joiners in London actually have to log on a job
- Bespoke vs flat-pack pricing — Voice-note "made on site" or "shop-built" and Holdfort prices labour and overheads correctly per model.
- FENSA / CERTASS for windows & doors — Scheme reference auto-prefixes external-door and window invoices.
- Timber sourcing receipts — Softwood / hardwood / sheet receipts auto-categorised with VAT split.
- Fire-door compliance (FD30/FD60) — Frame, hinges, intumescent, smoke seal each as their own line — landlords need this for FRA paperwork.
- Site-survey time — Billable survey separate from labour day rate.
What joiners 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 joiners
Yes. Set your FENSA number once; it auto-prefixes external windows and doors invoices and the building-regs notification reference attaches as a note.
Yes — voice-note "shop-built wardrobe, install on site Tuesday" and Holdfort splits the workshop time, materials and on-site fitting hours so the quote reflects real cost.
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.
