Job Management Software for Gas Safe & Water Regs: Which Tools Actually Handle Compliance?

Most job management software is built around quoting, scheduling, and invoicing. Compliance documentation is an afterthought — or absent entirely. For UK plumbers registered with Gas Safe, or those carrying out work under the Water Supply (Water Fittings) Regulations, this matters enormously. The wrong choice means running two separate systems: your job management tool for the commercial workflow, and a second system (paper, PDF, or specialist app) for every compliance record you're legally required to produce.

This guide covers exactly what each tool does and doesn't do across the compliance requirements that affect UK plumbing businesses in 2026.

The Compliance Requirements UK Plumbers Face

Before comparing the software, it's worth being precise about what "compliance" actually means here. There are four distinct areas:

1. Gas Safe Registration Records

Every gas fitting job must be notified to Gas Safe Register. The engineer must hold a current Gas Safe card for the appliance type being worked on. This is a regulatory requirement under the Gas Safety (Installation and Use) Regulations 1998. Software cannot replace the registration itself, but it can record the job notification reference and store evidence of engineer competency.

2. Gas Safety Records (CP12 / Landlord Certificates)

Landlords are legally required to have a Gas Safety Record completed annually for every gas appliance in a rented property. The Gas Safety (Installation and Use) Regulations require this to be carried out by a Gas Safe registered engineer and a record provided to the tenant within 28 days. The record must contain specific prescribed information: engineer name, registration number, appliance details, location, date, defects found, and whether the appliance was left safe to use. This is where most job management software fails — producing a legally valid Gas Safety Record (commonly called a CP12, though the official term is Landlord Gas Safety Record) requires a specifically structured certificate, not just a completed job note.

3. Legionella Risk Assessments

The Health and Safety Executive's Approved Code of Practice L8 requires landlords and responsible persons for commercial properties to assess and control the risk of Legionella bacteria in water systems. Plumbers are frequently instructed to carry out these assessments, particularly for larger residential landlords and commercial clients. The assessment must be documented, the risk level recorded, and control measures specified. The HSE does not prescribe a specific form, but the record must demonstrate that a systematic assessment was carried out.

4. Water Regulations Compliance (Water Fittings Notifications)

The Water Supply (Water Fittings) Regulations 1999 require that certain plumbing work — including new connections, most bathroom installations, and any alteration to a hot water system — is either approved in advance by the water undertaker, or carried out by an Approved Contractor (a business enrolled in a WaterSafe-approved scheme). Approved Contractors must self-certify their work using the scheme's notification system. The record-keeping obligation falls on the contractor, not the customer.

How Each Tool Handles Compliance

Powered Now: The Most Comprehensive UK Compliance Tool

Powered Now is the most complete UK compliance tool in this category. It has Gas Safety Record production built in as a long-established native feature — a properly structured certificate that meets the prescribed format for Landlord Gas Safety Records. Tradify has more recently added UK Landlord Gas Safety Record forms, but Powered Now's implementation is the more established of the two, and only Powered Now also covers Legionella risk assessments and native CIS — areas where Tradify has no equivalent. Engineers complete the Powered Now certificate on their phone or tablet at the point of service; the record is timestamped, attached to the job, and can be emailed to the landlord or tenant directly from the app.

The Gas Safe Record form in Powered Now captures all legally required fields: engineer name and Gas Safe registration number, appliance type and location, date of inspection, any defects identified, whether the appliance was left safe to use (the "safe to use" declaration is a specific legal requirement). This is not a notes field — it's a structured certificate that generates a formatted PDF matching the expected layout that landlords and letting agents recognise.

For Legionella, Powered Now includes a risk assessment template that covers the key areas required by L8: system description, uses and population, potential for water temperature issues, evidence of Legionella growth conditions, and the resulting risk rating with recommended control measures. Again, this generates a PDF that can be stored against the customer record and emailed on completion.

ServiceM8: Capable But Manual

ServiceM8 has a form builder that allows Gas Safe certificate templates to be created from scratch. It is genuinely capable — the platform supports conditional logic, required fields, photo attachments, and signature capture, which gives you the building blocks of a compliant Gas Safety Record. But the key word is "from scratch." ServiceM8 does not ship with a Gas Safety Record template. You would need to build one yourself, ensuring it captures all prescribed fields in a format that meets the regulatory requirement.

For a business with a developer or technically confident admin, this is achievable. For a plumbing business where the owner is also the lead engineer, building and validating a legally compliant certificate template is a significant undertaking. The same applies to Legionella — the capability is there, but the template is not.

There is a further limitation: ServiceM8 is iOS-first. Its Android app is significantly reduced in functionality, lacking time tracking and several other features available to iPhone users. For a plumbing team where engineers use a mix of phones, this creates a two-tier experience that undermines the compliance workflow — an engineer on Android may not have access to the same form capabilities.

ServiceM8 also does not support CIS invoicing. If your business operates as a subcontractor in the construction industry supply chain — common for plumbers working on commercial projects or new-build sites — ServiceM8 cannot produce CIS-compliant invoices without a significant workaround through accounting software.

Tradify: Gas Certs Added, Legionella and CIS Still Missing

Tradify has added UK Gas Safety Record forms to its feature set, including Landlord/Homeowner Gas Safety Records, Boiler Records, Central Heating Commissioning Certificates, and Gas Warning Notices. This is a meaningful change from a tool that historically had no gas compliance capability at all.

The remaining gap matters for many Gas Safe plumbers: no Legionella risk assessment templates, and CIS handling still routes through Xero rather than being native. For a plumber who carries out Legionella assessments alongside boiler servicing, Tradify's compliance coverage remains partial. For a plumber who only needs Gas Safety Records — boiler services, annual landlord checks, no commercial water system work — Tradify's new gas forms are worth evaluating alongside Powered Now's more established implementation.

For plumbers who do not do gas work — water-only, drainage, bathroom installation — Tradify remains the strongest choice for its quoting workflow and Xero integration. Water Regulations notifications are handled through the WaterSafe scheme's own portal regardless of which tool you use.

Jobber: Not Designed for UK Compliance

Jobber is a Canadian product. It handles the core job management workflow well — quoting, scheduling, invoicing, client communication — but it has no UK compliance features whatsoever. No Gas Safety Record capability, no Legionella templates, no CIS support, no Water Regulations notifications. It is priced at a team level rather than per user, which makes it more cost-effective for businesses with multiple staff, but that advantage does not outweigh the compliance gap for any Gas Safe registered plumbing business.

Jobber's strongest use case in UK plumbing is a larger water-only or drainage business — 5 or more field staff — where the compliance requirements are primarily covered by Water Regulations notifications through a WaterSafe scheme portal, and the primary challenge is managing team schedules, client communication, and cash flow. For that use case, Jobber is worth serious consideration. For any business doing gas work, it is not the right tool.

The Practical Decision

What "Custom Forms" Actually Means

ServiceM8 and Tradify's responses to compliance gaps often involve suggesting that users build custom forms. This deserves scrutiny. A custom form is not the same as a compliant certificate. For Gas Safety Records specifically, the Regulations prescribe what information the record must contain and that the engineer must sign it. A form that captures that information is a good start, but a certificate template that generates a properly formatted PDF — with your company name, the engineer's Gas Safe number, and a clear "safe to use" declaration — is what landlords, letting agents, and local authorities expect to see. Building that in a form builder, validating it against the regulatory requirements, and maintaining it as requirements change is a meaningful ongoing task.

Powered Now's Gas Safety Record form has been maintained against UK regulatory requirements since the product launched. That maintenance — knowing when a new field is required, when the format needs to change — is part of what the subscription funds. For most plumbing businesses, this is worth more than the flexibility of building from scratch.

Offline Working and Compliance

Gas safety and Legionella work often happens in locations with poor mobile signal: commercial basements, roof plant rooms, remote rural properties. This creates a practical problem for any compliance workflow that depends on cloud connectivity. Powered Now has offline capability — the certificate can be completed and signed without a signal, and it syncs when connectivity returns. Tradify requires signal. ServiceM8 has limited offline capability on iOS. Jobber is cloud-dependent.

For a plumber doing annual boiler services on a rural estate with patchy signal, offline working is not a nice-to-have. A certificate that cannot be completed on-site must be completed later from notes — introducing error risk and delaying the issue of the record to the landlord, which has its own regulatory timeline (28 days from completion).
