What plumbers in Manchester actually have to log on a job

- Building Regs Part G / Part H — Building-control sign-off PDF attaches inside the invoice thread.
What plumbers in Manchester actually deal with
United Utilities across the whole of Greater Manchester
Greater Manchester Clean Air Zone — plans paused since 2022 but councils are preparing a replacement scheme. Keep receipts for any Ultra Low Emission van upgrades; they’re capital allowance-eligible.
Ten boroughs (Manchester, Salford, Trafford, Bolton, Bury, Oldham, Rochdale, Stockport, Tameside, Wigan). Building Control for most residential jobs is split between council services and approved inspectors.
Heavy mix of Victorian two-up-two-downs, interwar semis, post-war council housing, and new-build apartment blocks especially around the city centre. Back-to-back terraces still need careful bracing on loft conversions.
Serving Didsbury, Chorlton, Sale, Altrincham, Withington and the rest of Greater Manchester. Manchester’s rapid apartment boom means lots of concierge-access jobs where you need a sign-in, a lift booking, and often a COSHH briefing before you can even touch a sink.
Greater Manchester sits around £50–£85 for a plumber callout, cheaper than London but increasingly comparable in city-centre postcodes. 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 Manchester plumbers
Yes. Set it once; every invoice and CP12 thereafter auto-prefixes the number, registration class and expiry — important for landlord work in Manchester where letting agents check before paying.
Yes — reply to the WhatsApp with the CP12 PDF and it attaches to the invoice thread. The landlord gets one document with the gas safety record and the invoice.
Yes — it’s UK-wide. Whether you’re invoicing a job in Manchester City Centre, a Salford Quays apartment, or a Stockport semi, the process is identical.
Log it as a voice-note line: "plus one hour sign-in and lift booking" and it goes on the invoice as a separate line. Your customer sees why the total’s higher than a like-for-like house call.
Landlords love fast PDFs for end-of-tenancy fixes. Voice-note a two-line fix-and-forward invoice from the van, send to the letting agent before you’ve left the driveway. Paid within days, not weeks.
Yes — quarterly-ready breakdowns and sole-trader categories. Required for self-employed earners over the MTD threshold from April 2026. See the MTD guide.
