Best Apps for Plumbers in the UK (2026)
A plumber first comparison of the apps UK trade businesses use for quoting, invoicing and job scheduling, with a close look at which ones automate repeat work such as annual boiler services and payment chasing. Checker, ServiceM8, Powered Now, Jobber, Gas Engineer Software, Joblogic and BigChange are compared on certificates, offline use, accounting sync and price.
Best Apps for Plumbers in the UK (2026)
A plumbing business rarely loses money on the tools in the van. It loses money in the gaps around the job: the quote a customer never replied to, the invoice that sat unpaid because nobody chased it, and the boiler service from last spring nobody thought to rebook this spring. This guide compares the apps UK plumbers actually use to run a job end to end, from a sole trader with one van to a small team of five or six.
By Daniel Sedgwick, Founder of Checker and a former gas engineer
Plumbing work splits fairly cleanly into two kinds of job: the one-off callout (a burst pipe, a blocked drain, a leaking tap) and the kind of work that is meant to repeat, a boiler service, a landlord’s annual gas safety check, a maintenance visit on a rental property. Most job management apps are built and marketed around the first kind. Few are built with the second in mind, even though repeat work is what turns month to month survival into something with a bit of predictability in the diary.
None of the apps below is the right answer for every plumbing business, and this list does not crown one tool the winner for every situation. It runs through what each one is actually built for, plainly enough that you can tell in a couple of minutes whether it fits how you work.
Key takeaways
- A plumbing app earns its keep twice: on the job (a fast quote, a job diary readable from a phone), and afterwards, chasing the invoice and getting the customer to rebook.
- If any of the work is gas or heating related, check whether an app produces the actual certificate, such as a CP12 landlord gas safety record, not just a job note saying the work happened.
- Few apps in this category automatically remind a customer that their annual service is due. Checker’s Annual Service Reminder fires around eleven months after a job record is created, offering the next booking before the customer forgets you exist.
- Checker’s Quote Chaser follows up an unanswered quote up to three times, and its Invoice Chaser does the same for an unpaid invoice, stopping the moment it is paid.
- Offline reliability matters more in this trade than most. A loft, a boiler cupboard or a rural job with no signal is a normal Tuesday, not an edge case.

ServiceM8
ServiceM8 runs on a visual job diary built to be operated entirely from a phone, suiting a plumber who wants to quote, log a job and invoice without a laptop that evening. Pricing follows job volume rather than a flat per-user fee: free for up to 30 jobs a month, then roughly £25, £59, £119 and £269 as volume climbs toward 1,500 jobs, all ex VAT, no contract, unlimited users on every paid tier. That rewards a quiet solo diary but gets expensive fast for a busy one.
ServiceM8 confirms genuine offline use directly: techs can log job details, add photos and notes with no signal, and everything syncs once the device reconnects. What it does not publish is a set of named UK compliance certificate templates such as CP12. It offers a general custom form builder instead, so a plumber who also does gas work should check that specifically before assuming it is covered.
Powered Now
Powered Now leans hard into paperwork speed: quotes, invoices and job sheets generated and sent from site rather than a desk back at the office. Its three tiers run £28, £32 and £40 a month per user, ex VAT, two months free if billed annually, and a 14-day trial that does not ask for a card. Automated chasing of quotes and invoices sits inside the Premium tier rather than the base plan, so check which tier you actually need before comparing headline prices.
Certificate coverage is broad for a plumbing and heating business. CP12 and CP2 gas records sit alongside electrical templates such as EICR and PAT, though these too are gated to Professional and above. Offline working is a genuine, vendor-confirmed strength: it works with no signal at all, and everything syncs once a connection returns.
Jobber
Jobber covers scheduling, quoting and invoicing for trades in several markets, including a growing number of UK businesses, built around a client list, a visual schedule and online payments. It is a reasonable general choice for a plumber wanting clean scheduling without a UK-specific setup, but its current UK pricing, certificate support and offline behaviour were not detailed on the pages checked for this guide, so confirm those directly if any of the three would decide it for you.
Checker
Checker starts from a different place than most of the apps above: a plumbing, gas, electrical and heating trade tool from the outset, rather than general job software with a UK certificate bolted on afterwards. Dan Sedgwick, its founder, spent years as a working gas engineer before he built it, which shows up in the detail of how the certificate side works rather than in a marketing line. Close to 19,600 UK trade users now run their businesses on it, and between them they have produced 6.88 million gas compliance reports.
What runs quietly in the background once a job is logged is where Checker separates itself from a straightforward quoting and invoicing app. An Annual Service Reminder fires around eleven months after a customer’s record is created, offering the next boiler service or landlord gas safety check before it is due rather than relying on a memory or a spreadsheet. A Quote Chaser follows up an unanswered quote up to three times, an Invoice Chaser does the same for an unpaid invoice until it is settled, and Appointment Reminders go out 24 hours before a booked job, all sent under the plumbing business’s own name.
On compliance, certificates such as CP12 landlord gas safety records generate from the same job record as the invoice, useful for a Gas Safe registered plumber doing heating and boiler work alongside general plumbing. Accounting syncs two-way with Xero, QuickBooks and Sage. Pricing runs per sub-user, Lite at £10.99, Pro at £19.99 and Pro Plus at £25.99, all plus VAT, month to month with no lock-in, and a master user sets what each team member can access. The app works with no signal too, syncing everything once a connection returns. Sign up at my.checker.app/register.
Gas Engineer Software
GES, short for Gas Engineer Software, is built for gas work only, a sole trader or small firm rather than the wider plumbing trade it sits alongside in this guide. CP12 landlord gas safety records, gas tightness tests and oil servicing records all come out of the product natively, and a basic set of customer reminders is included, though nothing built to the level of Checker’s automated annual-service sequence.
An annual plan starts around £18 a user a month, rising to roughly £30 for a Pro tier with accounting added. That price makes sense for a business that only ever touches gas, but a plumber doing bathroom fitting or non-gas heating alongside it will find the ceiling quickly.
Joblogic
Joblogic’s natural customer is a dozen engineers deep, not a one or two-van plumbing outfit: think commercial maintenance contracts spread across several client sites rather than a single domestic diary. £45 a user a month is the standard annual price, a 30-day trial and a monthly rolling option both exist as alternatives to signing up for the year, and Premium or Enterprise tiers move to a custom quote once a team passes 50 people.
Most plumbing businesses will find that more system, and more spend per head, than they need before they outgrow a small team. Whether it works offline on mobile is not something Joblogic publishes, so ask directly if a signal-free jobsite is part of your working week.
BigChange
BigChange goes well beyond job management into vehicle tracking and telematics, which makes sense for a plumbing and heating contractor running several vans and less sense for a one or two-van operation paying for tracking it does not need yet. There is no published price, only an enquiry form; third-party estimates for its older JobWatch product put fleet pricing somewhere around £70 to £100 per vehicle a month, though treat that as a rough guide rather than a confirmed figure.
Tracking is bundled into the core plan rather than sold as an extra, with add-ons such as AI dashcams and fuel cards on top. It is the heaviest, costliest option in this guide, and worth it once fleet visibility becomes a genuine daily problem rather than a nice-to-have.

Frequently asked questions
What’s the best app for a UK plumber to use day to day?
It depends on the shape of the business more than any single feature. A solo plumber doing mostly reactive callouts needs fast quoting and simple invoicing above all else, and ServiceM8, Powered Now and Jobber all cover that well. A plumbing and heating business that also does gas work, and relies on customers rebooking an annual service, tends to get more value from a tool built around that repeat cycle, which is what Checker’s Quote Chaser, Invoice Chaser and Annual Service Reminder are built to handle.
Do plumbers need software that reminds customers to rebook an annual boiler service?
Not strictly, plenty of plumbing businesses manage it from memory or a spreadsheet. But a missed rebooking is a lost job, and it usually goes to whichever engineer the customer finds next, not the one who did the work last year. Checker’s Annual Service Reminder fires automatically around eleven months after a customer’s record is created, offering the next booking before that gap opens up.
Can one app cover both gas and non-gas plumbing work?
Yes, though not every app does it well. Gas Engineer Software is built narrowly for gas certification and suits a gas-only sole trader, while general job management apps often treat gas certificates as an afterthought or leave them out entirely. Checker was built by a former gas engineer to cover UK gas, electrical, plumbing and heating work in one system, so a plumbing business that also holds Gas Safe registration is not stuck running two separate apps.
What’s the cheapest app for a sole trader plumber just starting out?
A few options are genuinely cheap to start with. ServiceM8 offers a Free tier for up to 30 jobs a month, Gas Engineer Software starts from around £18 a user a month for gas-only work, and Checker’s Lite plan starts at £10.99 a month per sub-user plus VAT with no lock-in contract. Compare what each one actually includes at that entry price, not just the headline figure.
Does plumbing software sync with Xero, QuickBooks or Sage?
It varies by tool, and is worth confirming directly rather than assuming. Checker offers two-way sync with all three, Xero, QuickBooks and Sage, so invoices and payments reconcile with the business’s accounts without manual re-entry.

Put The Repeat Work On Autopilot
If a good share of your work is the kind that is supposed to come back, an annual service, a landlord’s gas safety renewal, a repeat customer needing another job doing, Checker is built to make sure that work actually finds its way back to you instead of drifting to whoever the customer searches for next. Plans start at £10.99 a month per sub-user plus VAT, running month to month with no contract to sign.
