Best Apps for Plumbers in the UK 2026
Your phone is with you on every job. The right apps can transform how you run your plumbing business – saving hours on admin, helping you win more work, and making sure you get paid on time. Here’s what’s worth using in 2026.
Job management and quoting
Tradify
Best overall job management app for UK plumbers
Tradify is built specifically for the trades – and that shows in how it works day to day. It handles everything from first customer enquiry through to final invoice in one place: quoting, scheduling, job tracking, invoicing, and time tracking. Send a professional quote from your phone on site and convert it to an invoice the moment the job’s done.
- Professional quotes and invoices from your phone on site
- Trade-specific templates and materials markup built in
- Quote to job to invoice in one flow – no re-entering data
- Job scheduling and diary management
- Photo attachments – before and after photos on jobs
- Customer history stored automatically against every job
- Purchase orders for materials raised directly within a job
- Integrates with Xero and QuickBooks
Jobber
Worth considering if you need a client portal or stronger automation
Jobber is a well-rounded job management platform with stronger automation and client-facing features than Tradify. If automated follow-ups, a self-serve client portal where customers can approve quotes and pay online, or AI tools are priorities, Jobber is worth a look.
- Automated quote follow-ups and payment reminders
- Client self-serve portal – customers approve quotes and pay online
- Two-way text messaging built in
- AI tools via Jobber Copilot
- Reporting dashboards showing where revenue is coming from
