Plumbing Software (2026): 7 Best UK Apps Compared

Plumbing software runs quotes, jobs and invoices, and sometimes gas certificates.

The right one depends on how many of you need a login, whether you issue CP12s, and how you’d rather pay: per user, per business or per job.

Below are 7 UK options with their published price, who each one suits, and one honest watch-out each.

7 apps for plumbers and heating engineers, smallest business first

Every card has the same four parts: who it suits, the published price, what it does for you, and one watch-out.

1

FieldHive

Suits: Sole-trader plumbers and owner-run firms of up to about 3 people, where you do the quoting, booking and invoicing.

Published price

Free plan · Business £14.99 a month or £144 a year, one price for the whole business.

  • Quote fixed-price, by the hour, or time and materials. A bathroom refit and a leak call-out rarely price the same way.
  • Quote → booking → invoice from one customer record. Xero and QuickBooks sync with CIS, Stripe card payments and a customer portal, all on the free plan.
  • Save your fittings and labour times as catalogue items, unlimited on the free plan. Deposits and progress claims for staged installs are on Business.
  • Stop paying any time and you keep the free plan. Your quotes and invoices stay yours to export.

Watch-out: No gas safety (CP12) certificates, in the app or as a free form, so gas work needs a separate certificate app. And it’s one login, for the person who runs the admin: staff don’t get their own accounts, job lists or timesheets. For CP12s in the same app, Powered Now, Commusoft or Joblogic suit you better; if every engineer needs a login, Tradify.

Start free

Free plan, no card needed. £14.99 a month flat for the whole business when you need more.

2

ServiceM8

Suits: Service and call-out plumbers on short jobs, priced by monthly job count rather than people.

Published price

Free for 1 user and 30 jobs a month · paid plans £25 to £269 a month by job volume, unlimited users.

  • Unlimited users on paid plans. Add staff without adding seats.
  • Xero and QuickBooks on every plan, including free.

Watch-out: Priced by how many jobs you do a month. A plumber doing lots of short call-outs can pass the free plan’s 30 quickly, and a busy month can push you onto the next plan.

3

Powered Now

Suits: Plumbing and heating firms that want gas certificates and the accounts in the same app as quotes and invoices.

Published price

Business £28 a month for one user · Professional £32 and Premium £40 per user a month · 14-day trial.

  • Gas, electrical and other trade certificates plus custom forms, from Professional (£32 per user).
  • Pay-now links on invoices and a mobile card reader for payments on site.

Watch-out: The £28 plan is for one user and has no certificates. Teams, Xero and QuickBooks sync, and certificates start on Professional (£32 per user); the customer portal is on Premium (£40 per user) only.

4

Tradify

Suits: Plumbing and heating teams of 2 to 10 who schedule several engineers across the week.

Published price

£34, £37 or £44 per user a month · 14-day trial.

  • Compliance certificates, timesheets and progress invoicing from Pro (£37).
  • Xero, Sage and QuickBooks on every plan, including Lite (£34).

Watch-out: The bill grows with every user, and certificates aren’t on Lite. No customer portal found on its site; customers get emailed links.

5

Fergus

Suits: Plumbing contractors who want to see the profit on every job.

Published price

Essentials from £39 a month, Professional from £45 · timesheet users from £12 a month · 14-day trial.

  • Job costing built around labour and materials.
  • Xero and QuickBooks on both plans; card payments at 1.6% + 20p.

Watch-out: Its pages describe storing certificates against the job, not filling in a CP12, so gas engineers may still need a certificate app. No customer portal; customers get a payment page.

6

Commusoft

Suits: Plumbing and heating firms with office staff, engineers on the road and service contracts.

Published price

Price on request: plans aren’t published. Contracted licences run for 12 months; monthly and daily licences can be added.

  • Landlord gas safety certificates (CP12) and other forms filled in on the mobile app and sent straight away.
  • Service reminders and online booking for contract customers, plus a self-service customer portal.

Watch-out: No published price, so you book a call to get one. Every office user and engineer needs a licence, contracted licences commit you for 12 months, and onboarding is part of the package.

7

Joblogic

Suits: Plumbing, heating and gas maintenance contractors with office staff and planned maintenance work.

Published price

Standard from £45 per user a month, billed annually (5 users = £225 a month).

  • CP12, landlord gas safety and F-Gas certificates issued from the van, with records kept against the site.
  • Live sync with Sage 50, Xero and QuickBooks.

Watch-out: Most customers sign 24- or 36-month contracts (12 months on request). Every office and field login is a paid user, and the customer portal is on Enterprise only.

Before you choose a plumber app

How we compared

Published prices only

We read each vendor’s own UK pricing page on 7 October 2026: entry price, free plan, how they charge, gas certificates and accounting sync. Where a vendor doesn’t publish a price, we say so.

No vendor paid to appear. FieldHive is our product, and its watch-out is on its card like everyone else’s.

What to check

How plumbers and heating engineers choose software

  • Decide where gas certificates live: in the job app or in a separate certificate app.
  • Check which plan the certificates are on. At Powered Now and Tradify it’s the second plan.
  • Count who needs their own login; per-user pricing multiplies by it.
  • Count your call-outs a month: job-volume plans charge by it.
  • Trial it on real jobs before any 12-, 24- or 36-month contract.
Honest limit

When a heating firm needs more than FieldHive

If you issue CP12s and want them saved against the job, pick an app with gas certificates built in: Powered Now from £32 per user, or Commusoft and Joblogic for firms with office staff. If each engineer needs their own login, timesheets or assigned jobs, Tradify or ServiceM8 suit a team better.

Software for plumbers: common questions

What is the best plumbing software in the UK?

It depends on whether you issue gas certificates and how many logins you need. Working alone or running the jobs for up to about three people, with CP12s done elsewhere: FieldHive is free to start and £14.99 a month. Gas certificates in the same app: Powered Now from £32 per user, or Commusoft and Joblogic for firms with office staff. A team where every engineer logs in: Tradify or ServiceM8.

Is there a free app for plumbers?

Yes, two of the seven have a free plan. FieldHive’s needs no card and includes up to 5 active quotes, unlimited invoices, bookings, customers and catalogue items, and Xero and QuickBooks sync. ServiceM8 is free for 1 user and 30 jobs a month. The others offer a trial or a demo, not a free plan.

Can I do gas safety certificates (CP12) in FieldHive?

No. FieldHive doesn’t do gas safety certificates, in the app or as a free form. It handles quotes, bookings and invoices. For CP12s in the same app, Powered Now has gas certificates from its £32 Professional plan, and Commusoft and Joblogic both list landlord gas safety certificates.

Can my plumbers use FieldHive?

Not with their own logins. The person who runs the business quotes, books and invoices every job in FieldHive; staff don’t log in, see their own job lists or fill in timesheets. That suits owner-run firms of up to about three people. If each engineer needs an account, Tradify, ServiceM8 or Powered Now fit better.

Which plumber apps sync with Xero and QuickBooks?

FieldHive does on the free plan, with CIS; ServiceM8 on every plan, including free; Tradify on every plan, plus Sage; Fergus on both plans. Powered Now syncs from Professional (£32 per user). Joblogic syncs live with Sage 50, Xero and QuickBooks but doesn’t publish which tier, and Commusoft lists a Xero integration.

How much does software for plumbers cost?

From £0 to about £45 per user a month on published UK prices, as of October 2026; Commusoft quotes on request. For one person that is £0 to £540 a year. For a three-person team on per-user pricing, expect roughly £1,150 to £1,620 a year.

One flat price for the whole business.

Plumbing software doesn’t have to mean a bill per engineer. Start on the FieldHive free plan, no card needed, with quotes, invoices, bookings, your price list and the customer portal. Move to £14.99 a month when you need unlimited quotes, deposits, progress claims and reminders. Stop paying any time and you keep the free plan, with your quotes and invoices yours to export.
