Best Plumbing Software UK: 5 Tools Compared (2026)

The best plumbing job management software for UK plumbers depends on team size and job volume. If you are looking for plumbing software UK firms actually use day to day, three tools lead the field: Tradify (from £34/user/month) for solo plumbers and small teams wanting simple quoting and Xero integration, ServiceM8 (from £29/month, per-job pricing) for growing teams of three to ten engineers where per-seat costs would add up fast, and Commusoft (from £99/month) for established firms with six or more staff who need stock management and automated customer communications.

But there are five serious contenders, not three, and the right choice also depends on whether you need Gas Safe certificates built into the software, how your pricing model works, and whether you want a client-facing portal. This guide breaks down all five with real UK pricing, compliance features, and the practical detail that matters when you are choosing a tool you will use every day for the next two or three years.

ServiceM8

Per-Job Pricing That Scales Without Per-Seat Costs

ServiceM8 is an Australian-built field service platform that has built a strong following among UK plumbers, particularly one- to five-person firms that run a high volume of jobs. Its defining feature is the pricing model: instead of charging per user, ServiceM8 charges per job. The Starter plan at £29 per month covers up to 50 jobs. The Growing plan at £49 per month covers up to 150 jobs. The Premium plan at £59 per month is unlimited. Every plan includes unlimited users, which means you can add an apprentice, a partner, or office staff without the bill climbing.

The mobile app is genuinely good. It was built for field workers first, not adapted from a desktop product, and it shows. You can create a job, take photos, capture a customer signature, and send the invoice from the van. The scheduling calendar supports drag-and-drop dispatching if you have someone in the office, and engineers can see their day on their phone in real time.

For plumbers specifically, the job forms feature lets you build custom checklists and capture data like boiler serial numbers, Gas Safe registration details, and CP12 information. These are not native Gas Safe certificates — you are building a form that collects the data, not generating an official compliance document — but for many plumbers that is enough. The data is stored against the job and can be emailed to the customer as a PDF.

Xero integration is straightforward. Completed jobs sync across as invoices, and the account code mapping is clean. ServiceM8 also integrates with Stripe for card payments on site, which is useful for emergency call-outs where you want to collect before you leave.

The weakness is UK-specific compliance. ServiceM8 does not generate Gas Safe certificates, electrical certificates, or handle CIS Domestic Reverse Charge VAT natively. If you need those, you are bolting on a second tool or building workarounds. For a plumber who does not touch gas, that is fine. For a gas engineer, it is a gap worth thinking about.

Best for: solo plumbers and small teams running high volumes of reactive and emergency work where per-user pricing would be expensive and speed of invoicing matters most.

Commusoft

Built in London for UK Trades Since 2006

Commusoft is the heavyweight in this comparison. Based in London and built specifically for UK field service businesses, it has been around since 2006 and is used by plumbing and heating firms across the country. The entry price reflects that depth: paid plans start at around £99 per month, and larger firms on custom contracts will pay considerably more.

What you get for that price is a genuinely complete system. Job management, quoting, invoicing, scheduling, dispatching, stock and parts management, customer communications, and reporting are all built in. The stock management module is particularly strong — you can track parts across vans, set reorder levels, and see what each engineer is carrying. For a plumbing firm that stocks boiler parts, valves, and fittings across multiple vehicles, that alone can justify the cost.

The automated customer communications are the other standout. Commusoft can send booking confirmations, on-the-way text messages, appointment reminders, and follow-up emails without anyone in the office touching a button. For firms that employ office staff and want to project a professional, large-company image, this is the feature that separates Commusoft from the lighter tools.

Gas Safe compliance is handled through custom forms rather than native certificate generation. You can build forms that capture all the data required for a Gas Safe record and attach them to the job, but Commusoft does not generate the official certificates. For most plumbing firms with gas engineers, this means either printing certificates separately or using a bolt-on.

Xero integration is deep. Invoices, payments, and credit notes all sync, and the job-costing reports let you see profitability by job, by engineer, and by customer. The reporting is the best of the five tools here — if you want to know which types of job make you money and which do not, Commusoft gives you that data.

The weakness is the price and complexity barrier. A solo plumber paying £99 per month for software they use to quote, schedule, and invoice is overpaying for capacity they will never touch. The stock management, dispatch board, and automated communications earn their keep when you have an office manager and multiple vans. Below that size, they are overhead.

Best for: established plumbing and heating firms with six or more staff, an office, and a need for stock tracking, automated customer comms, and detailed financial reporting.

Tradify

The Simplest Path from Paper to Digital

Tradify is a New Zealand-built platform that has become one of the most popular job management tools among UK tradespeople, and for good reason: it is simple. The interface is designed for people who fix pipes, not people who configure software. Quote, job, invoice — that is the core loop, and Tradify makes it fast.

Pricing is per user: £34 per month on the Lite plan, £44 per month on the Plus plan which adds digital forms, purchase orders, and progress invoicing. Every plan includes a 14-day free trial with no card required, so you can test it with real jobs before committing.

The quoting workflow is where Tradify shines. You can build a quote on site from your phone, using saved price lists and templates, and send it to the customer before you have left their driveway. When they accept, it converts to a job. When the job is done, it converts to an invoice. That single thread — quote to job to invoice with no retyping — is the thing that saves most plumbers an hour a day compared to doing it by hand or across multiple tools. Pair it with AI prompts built for plumbing quotes and the quoting step drops from minutes to seconds.

Xero integration is widely regarded as the cleanest in the category. Invoices flow into Xero automatically, account codes map correctly, and the bank feed matches payments without manual reconciliation. If you already use Xero or your accountant insists on it, Tradify is the easiest platform to connect.

The weakness for plumbers is compliance. Tradify does not have native Gas Safe certificate generation. The Plus plan includes custom digital forms, which you can use to capture Gas Safe data, but you are not getting an official certificate out of the software. There is also no native CIS handling for plumbers who subcontract on commercial sites. For a domestic plumber who does not touch gas, neither gap matters. For a gas engineer or a firm doing CIS work, it is a limitation.

Reporting is functional but not deep. You can see revenue, outstanding invoices, and job status. You cannot easily drill into profitability by job type or engineer productivity the way you can with Commusoft. For most small firms, the basic reports are enough. If you are trying to optimise margins across a team, you will outgrow them.

Best for: plumbers adopting job management software for the first time, small teams of one to five who want fast quoting, clean Xero sync, and minimal setup friction.

Powered Now

The Only One With Built-In Gas Safe Certificates

Powered Now is the outlier in this comparison, and for gas engineers it may be the most important one. It is the only platform of the five that generates official Gas Safe certificates natively — not via custom forms, not via a bolt-on, but built into the core product. You finish a boiler install, open the certificate template on your phone, fill in the details, and email the signed certificate to the customer and your Gas Safe record before you leave site.

The software is UK-built and UK-focused. Pricing starts at £28 per user per month on the Business plan, £32 on Professional, and £40 on Premium. The Professional and Premium tiers add features like automated quote and invoice chasing, which sends follow-up reminders to customers who have not responded or paid without you lifting a finger.

Beyond Gas Safe, Powered Now also generates electrical certificates (EIC, EICR, Minor Works), building regulations compliance documents, and various other trade-specific paperwork. For a plumber who also does gas work — which is most plumbers — this collapses two tools into one. You are not running job management software and a separate certificate app.

The offline capability is worth mentioning because it matters in practice. Powered Now works fully offline and syncs when you get back to a signal. If you spend half your week in basements, plant rooms, or rural properties with poor coverage, this is not a gimmick — it is the difference between completing paperwork on site and doing it in the car park afterwards.

Xero integration works and handles CIS Domestic Reverse Charge VAT, which matters if you subcontract on commercial jobs. Making Tax Digital compliance is also built in, so your VAT submissions route through correctly.

The weakness is the interface. Powered Now is functional rather than beautiful. The quoting and job management workflow is not as slick as Tradify, and the learning curve is slightly steeper. Reporting is adequate but not as sophisticated as Commusoft. You are trading polish for compliance depth, and for many UK plumbers that is the right trade.

Best for: plumbers and gas engineers who need Gas Safe certificates, electrical certificates, or other UK compliance documents built into their job management software without running a second app.

Jobber

The Client Experience Platform

Jobber is a Canadian platform that has been steadily growing its UK user base. The Core plan starts at £31 per month for a single user. The Connect plan at around £134 per month supports up to five users and adds the features that make Jobber distinctive: a full client portal, online quote approval, and online payment.

The client portal is genuinely the best of the five. Your customers get a branded login where they can view quotes, approve them with a click, see upcoming appointments, pay invoices online, and request new work. For a domestic plumber whose customers are homeowners used to online booking and self-service, this polished experience sets you apart from competitors sending PDF quotes by email.

Route optimisation is the other headline feature. If you run multiple small jobs across a town or region — unblocking drains, fitting taps, annual boiler services — Jobber maps your day and sequences the jobs to minimise driving. The offline mode, added in January 2026, means the app remains usable in areas with patchy signal, though it is not as mature as Powered Now's offline capability.

Xero integration works, and Jobber's own invoicing and payment collection are strong. You can take card payments on site through the app, and the automated payment reminders reduce the amount of chasing you do manually.

The weakness for UK plumbers is fundamental: Jobber is built for the North American market. There are no Gas Safe certificate templates, no CIS Domestic Reverse Charge VAT handling, no Making Tax Digital integration, and no native UK compliance features. Everything that makes a UK plumbing business different from a Canadian one is absent. You can work around some of it with custom fields and third-party tools, but at that point you are fighting the platform rather than using it.

The pricing also climbs steeply. The jump from Core (one user, £31) to Connect (up to five users, £134) is significant, and the Grow plan for larger teams pushes past £200 per month. Per-user, it becomes one of the most expensive options once you add a second or third person.

Best for: domestic plumbers running lots of small jobs across a region who want the best client-facing experience and are willing to handle UK compliance outside the software.

How to Choose

The decision comes down to four questions. Answer them honestly and the right tool usually picks itself. If admin time is the bigger problem than software choice, read how UK plumbers are using AI to cut admin time first — it may solve the bottleneck before you spend anything on job management.

How big is your team? Solo plumbers and pairs should look at Tradify or Powered Now — both are affordable per-user and simple to set up. Teams of three to ten where per-user costs add up should consider ServiceM8's per-job model. Firms with six or more staff and an office should evaluate Commusoft.

Do you need Gas Safe certificates? If yes, Powered Now is the only platform with built-in Gas Safe certificate generation. Every other tool requires a workaround or a second app. For plumbers who also do gas work, this is often the deciding factor.

What is your budget? The cheapest entry point is Powered Now at £28 per user per month. The cheapest way to scale a team is ServiceM8's per-job pricing with unlimited users. If budget is tight and you do not need certificates, Tradify Lite at £34 per user is the sweet spot of simplicity and value.

Do you already use Xero? All five integrate with Xero, but Tradify's integration is consistently rated the smoothest. If your accountant has you on Xero and clean bookkeeping is a priority, Tradify makes the connection painless.

Verdict

For most UK plumbers choosing their first job management software, Tradify is the safest starting point — fast quoting, clean Xero sync, minimal learning curve. If you do gas work and need certificates, Powered Now is the obvious choice and often cheaper. If you are running a growing firm with multiple vans and want depth in stock management and reporting, Commusoft earns its higher price. If you run high-volume reactive work and want to avoid per-user costs, ServiceM8 scales better than anything else here. And if client experience is your competitive edge and you can handle compliance elsewhere, Jobber delivers the most polished customer-facing portal in the category.

Whichever you choose, set up an AI assistant alongside it to handle quoting and customer replies, connect it to Xero on day one, run one real job through the full cycle before you commit, and do not buy for the firm you hope to be in five years — buy for the one you run today.
