Tradify Review for Gas Engineers UK (2026)
Tradify is the most widely recommended job management app among UK tradespeople — but most of the reviews out there are from electricians and plumbers. This review focuses specifically on whether Tradify works for gas engineers: boiler callouts, landlord certificates, large installation quotes, CIS subcontract work, and MTD compliance. The short answer is yes — with one important caveat covered below.
What Tradify Does for Gas Engineers
Quoting
Build a saved library of standard line items — boiler supply, flue extension, magnetic filter, labour rate, part P compliance — and set your standard prices once. When a new installation quote comes in, open the app, select the appliances and labour, adjust quantities, and send a professional PDF to the customer before you’ve left the property. Customers see your logo, their address, a full breakdown, and your payment terms. You get a read receipt the moment they open it.
Job Management and Scheduling
Every accepted quote converts to a live job card with one tap. The job card holds everything: customer contact details, site address, what appliances are involved, job notes, photos, parts ordered, and times on site. The scheduling calendar shows all jobs in a drag-and-drop view — move callouts around when emergency work comes in, assign to specific engineers if you have a team, and see the full week at a glance.
Invoicing and Deposits
When a callout is marked complete, raise the invoice in two taps. For boiler replacements, raise a deposit invoice before ordering parts and track the outstanding balance against the final invoice automatically. Tradify sends automatic payment reminders at intervals you set, so you’re not manually chasing outstanding invoices. For gas engineers with 15+ live invoices at any time, this alone is worth the subscription cost.
CIS Subcontractor Support
Tradify handles CIS deductions on subcontractor invoices. If you use subbies on larger heating system installations and need to deduct CIS correctly, Tradify manages this natively — which is something a lot of gas engineers discover they need only after making an error at year end.
Accounting Integration
Tradify connects to Xero and QuickBooks. Your invoices, expenses, and CIS deductions sync automatically — no double entry, and your VAT returns and MTD quarterly submissions are handled through whichever platform your accountant uses. MTD for Income Tax is already live for sole traders above £50,000 and extends to £30,000 from April 2027.
Honest Pros and Cons for Gas Engineers
| Pros | Cons |
|---|---|
| Built for UK tradespeople — VAT and CIS handled correctly | No CP12 certificate templates built in |
| Fast quoting from phone on site visit | No gas-specific service contract management |
| Deposit invoicing for boiler replacements | No automated annual landlord certificate reminders |
| Automatic payment reminders | No native card payment processing (unlike Jobber) |
| Full CIS deduction support | Takes a couple of evenings to set up properly |
| Xero and QuickBooks integration for MTD | Less gas-specific than Commusoft |
| ~£34/month — strong value for what it covers | No free plan |
The One Caveat: Commusoft
The main limitation of Tradify for gas engineers is that it’s a general trades tool, not a gas-specific one. It doesn’t have CP12 certificate templates built in. It doesn’t manage service contracts or send automated annual landlord renewal reminders. For a gas business where service contracts and regular landlord certificates are the financial backbone, Commusoft is the more purpose-built option — though it starts at around £89/month and has a steeper setup curve.
For most gas engineers — particularly sole traders and small firms — Tradify at £34/month covers the job management, quoting, invoicing, and compliance that matters on a daily basis. Commusoft is worth considering once your service contract volume is large enough that manual renewal tracking becomes a real problem.
Is Tradify Worth It for a UK Gas Engineer?
At ~£34/month, Tradify pays for itself if it gets you one boiler replacement deposit before you’ve ordered parts, gets you paid 7 days faster on a callout average, or saves you two hours of admin time per week. For most gas engineers currently quoting by phone and invoicing from a pad at the kitchen table, the ROI is not close — it pays for itself many times over.
Verdict: yes, it’s worth it for most UK gas engineers. The 14-day free trial is risk-free — run it alongside your current system for two weeks on real jobs and see the difference.
Tradify vs the Alternatives for Gas Engineers
Tradify
Best starting point for most UK gas engineers. Full job lifecycle from quote to invoice at ~£34/month. UK-built, CIS-compliant, connects to your accountant.
Jobber
Worth looking at if card payments on callout invoices are a priority — the client portal and payment links make a real difference to how fast residential customers pay.
Frequently Asked Questions
Yes, for most gas engineers. Tradify handles quoting, scheduling, deposit invoicing for boiler installations, CIS deductions, and Xero/QuickBooks integration for MTD compliance. The key limitation is that it lacks gas-specific features like CP12 certificate templates and automated annual landlord renewal reminders — for which Commusoft is the better specialist option at a higher price.
Yes. Tradify handles CIS deductions on subcontractor invoices natively. If you use subbies on larger heating system installations and need to deduct CIS at the correct rate, Tradify manages this automatically and the deductions sync to Xero or QuickBooks for your accountant.
Tradify is the best starting point for most UK gas engineers — it covers the full job lifecycle from quote to invoice at around £34/month with CIS support and accounting integration. Commusoft is better if gas service contracts and automated CP12 certificate management are central to your business, but costs significantly more. Jobber is worth considering if fast card payment on residential callouts is a priority.
Tradify does not have built-in CP12 certificate templates or automated annual renewal reminders. You can create custom job templates and notes to manage the workflow, but it is not a gas-specific compliance tool. If landlord certificate management is central to your business, Commusoft handles this more completely with purpose-built gas compliance features.
Tradify costs approximately £34 per user per month for a sole trader gas engineer. There is no free plan, but there is a 14-day free trial with no credit card required. For a gas engineer who currently loses margin on late invoices, underpriced boiler quotes, or untracked CIS deductions, the subscription typically pays for itself within the first month.
Yes. Tradify connects directly to both Xero and QuickBooks. Invoices, expenses, and CIS deductions sync automatically so there is no double entry. MTD for Income Tax is live for sole traders above £50,000 in 2026 and extends to £30,000 from April 2027 — whichever platform your accountant uses, Tradify feeds the data into it cleanly.
