How much should a plumbing CRM cost in the UK?

For a sole trader, expect £15–£35 a month. For a small team (3–8 engineers), realistically £40–£70 per user per month once you factor in payment processing and add-ons. Anything above £100 per user per month should come with a very good reason — usually deep features like Gas Safe certificate management or multi-trade dispatching. Budget another £200–£1,000 for setup if you want it done properly.

Does my plumbing business really need a CRM?

If you're a one-van Wirral plumbing business doing 5 jobs a week and your diary fits in your head, probably not yet — a good calendar app and Stripe will get you through. The moment you hit two engineers, or 30+ jobs a month, or you're losing track of who needs a follow-up service, it stops being optional. The hidden cost of not having one is missed jobs, late invoices, and customers who never hear from you again.

Can I just use Google Sheets or Excel instead of a CRM?

For about six months, yes. After that it falls apart. Spreadsheets don't send invoices, don't take card payments, don't sync to your engineer's phone, and don't remind Mrs Jones her annual boiler service is due. They're brilliant for one-off lists. They're terrible as the central nervous system of a growing plumbing business.

What's the best free CRM for plumbers?

Honest answer — there isn't one worth using long-term. HubSpot's free tier exists but it's built for sales teams, not field engineers. ServiceM8 has a free starter with limited job credits which is fine for a couple of months while you test it. For anything sustained, budget at least £20–£30 a month. Free CRMs cost you in lost jobs and chaos.

How long does it take to set up a plumbing CRM properly?

A weekend of focused work to get the basics in — customer import, job types, quote and invoice templates, payment integration. Another 2–3 weeks of using it daily before it feels natural. Allow 6–8 weeks before it's properly embedded across the team. Trying to roll it out during your busiest month is the classic mistake — pick a quieter period.

How to Choose a CRM for Your Plumbing Business (Without Getting Ripped Off)

Picking a CRM for your plumbing business — whether you're a sole-trader sparky or one of the larger Wirral plumbing businesses — is one of those jobs that sits on the “I’ll deal with it next month” list for about three years. Then a customer rings asking when you fitted their boiler, you can’t find the job sheet, and you realise the right plumbing CRM would have saved you the awkward phone call. This guide is the honest version — what these systems actually do, which ones are worth your money in the UK, and which ones will quietly stitch you up.

No affiliate links, no “top 10 best ever” nonsense. Just what we’ve seen working (and not working) for plumbers running anything from a one-van outfit to a 12-engineer firm.

What a CRM actually does for a plumbing business (in plain English)

Forget the marketing waffle. For a plumber, a CRM is just one box that holds all the stuff that used to live in six places — your phone contacts, the kitchen-drawer diary, the quote pad in the van, the invoice book, the photos on your phone of that dodgy stopcock, and the Stripe app for taking card payments.

That’s it. If a system promises you “AI-powered customer journey orchestration”, run. You want software that does these six boring things, properly:

Customer list — name, address, phone, what you’ve done for them before
Job calendar — who’s where, when, with which van
Quotes — sent from the kitchen, accepted by text
Invoices — out the door before you’ve left the driveway
Photo and note storage — attached to the job, not floating in your camera roll
Payments — card on site, or a pay-by-link in the invoice

If a CRM does those six things well on a phone, you’re 90% of the way there. Everything else is gravy.

Why generic CRMs like HubSpot and Salesforce are wrong for plumbers

HubSpot is brilliant if you’re a SaaS startup chasing enterprise deals. For a two-van plumbing outfit in Birmingham, it’s a sledgehammer for a thumbtack. The features you’d actually use cost more than your van payment, and the ones you’re paying for — sales pipelines, marketing automation, deal stages — are designed for someone trying to close a £50k contract over six months, not someone fitting a megaflo on Tuesday.

Here’s why the big-name generic CRMs miss the mark for plumbers:

Built for sales teams, not field engineers. The whole interface assumes you’re sitting at a desk moving “leads” through a “pipeline”. A plumber’s pipeline is the diary, not a Kanban board.
No scheduling-from-the-van. You can’t drop a follow-up job into Wednesday afternoon while you’re standing in someone’s airing cupboard.
Pricing model is wrong. Per-user pricing kills you when you’ve got six engineers who each need access. £40 a user a month adds up fast.
No invoicing or payments. You still need Xero, Stripe, and three other tools bolted on.
No photo-to-job workflow. Trying to attach a picture of a corroded valve to a customer record in Salesforce is genuinely painful.

Generic CRMs aren’t bad software. They’re just not built for someone who spends their day under sinks.

The 6 things a plumbing CRM MUST do

If you take nothing else from this article, take this list. These are non-negotiable. If a system can’t tick all six, keep looking.

1. Mobile-first (not “mobile-friendly”)

Your engineer is using this on a phone, one-handed, in a leaky kitchen, possibly with gloves still on. Half the “mobile-friendly” CRMs out there are basically the desktop site squashed onto a phone screen. Test it before you buy — make whoever’s selling it to you open the app on a phone and book a job in under 30 seconds.

2. Two-way calendar sync

Google Calendar at the absolute minimum. If you book a dentist appointment in your personal calendar, your CRM should know not to drop a job on top of it. One-way sync is a recipe for double-bookings.

3. Quote to invoice in two taps

You quoted £480 for the work. Customer says yes. You should be able to convert that quote into an invoice without re-typing anything. Most modern systems do this. Some still don’t. Walk away from the ones that don’t.

4. Customer job history (last 5 years visible)

When Mrs Patel rings about a boiler you serviced in 2022, you want to see exactly what you did, what parts went in, and what photos you took — within ten seconds. This is the difference between looking like a pro and looking like you’re winging it.

5. Photo upload from the job

Snap, attach, done. Before-and-after photos protect you in disputes, help with insurance claims, and make your quotes look serious. The good systems let you mark up photos — circle the leak, add an arrow, write a note.

6. Payment collection

Card terminal in the van or pay-by-link in the invoice. Both, ideally. Getting paid on the day, before you’ve packed up your tools, is the single biggest cashflow improvement a plumber can make. If the CRM can’t take a card payment, it’s missing a quarter of the value.

A CRM that doesn’t open on your phone, in a wet kitchen, with your gloves still on — is just expensive Excel.

Honest comparison: the main plumbing CRMs in the UK

Right. The actual options. Prices are correct as of mid-2026 — they’ll have crept up by the time you read this, so always check directly. We’ve kept this brutally honest.

ServiceM8

ServiceM8 is probably the most popular field-service app among UK plumbers, electricians and gas engineers. It’s Australian originally, but the UK uptake is huge.

Pros: Genuinely mobile-first. Quoting, invoicing, photos, online booking — all slick. Pay-as-you-go pricing (you buy job credits) means a quiet month costs you less.
Cons: iOS-only on mobile for engineers — if your team’s on Android, that’s a problem. The credit-based pricing gets expensive once you’re doing 200+ jobs a month.
Who it fits: 1–8 engineer outfits on iPhones, doing reactive and small project work.
UK pricing: From around £29/month base plus job credits (rough rule: £1 per job once you’re past the free allowance).

Tradify

New Zealand-built, popular here. Cleaner interface than most, decent UK support.

Pros: Works on iOS and Android. Good Xero and QuickBooks integration. Simple pricing — you know what you’re paying.
Cons: Scheduling is weaker than ServiceM8. The reporting is fairly basic if you want to know which jobs actually make money.
Who it fits: Solo plumbers up to about 5 engineers who want clean and simple, not feature-bloated.
UK pricing: Around £35/user/month.

Jobber

Canadian, growing fast in the UK. Strong on the customer-facing side — online booking, client hub, automated reminders.

Pros: Best-in-class client communication. Automated review requests, appointment reminders, follow-ups. The customer hub looks properly professional.
Cons: Pricier than the alternatives. Aimed slightly more at home services generally (cleaners, landscapers) than plumbing specifically — some workflows feel a touch off.
Who it fits: Plumbers who do a lot of domestic recurring work and care about their customer experience.
UK pricing: Around £45–£199/month depending on plan.

Commusoft

Commusoft is the UK heavyweight. Built specifically for UK plumbing, heating and gas firms. Used by a lot of the bigger names.

Pros: Deepest feature set on this list. Gas Safe certificate management, parts inventory, multi-engineer dispatching, proper service plan management. Built for UK rules.
Cons: Steep learning curve. Expensive. Overkill if you’re under five engineers — you’ll pay for features you never touch.
Who it fits: Established UK heating/plumbing firms, 8+ engineers, doing maintenance contracts and Gas Safe work at scale.
UK pricing: From around £69/user/month, with setup fees on top. Properly budget for it.

Powered Now

UK-built, UK-focused, aimed at smaller trades businesses.

Pros: Sensible UK pricing. CIS-aware. Decent quoting and invoicing. Works offline, which actually matters when you’re under someone’s house.
Cons: The interface looks dated next to Jobber or ServiceM8. Scheduling features are basic compared to the bigger players.
Who it fits: Sole traders and 1–3 engineer firms who want UK-built, no-faff software at a fair price.
UK pricing: From around £15/month for solo, £30+ for teams.

Red flags when buying a CRM

The sales calls all sound great. Here’s what to actually watch for before you sign anything:

Annual contracts with no monthly option. If they won’t let you go monthly, they’re worried you’ll leave. Run.
Hidden setup or “onboarding” fees. Always ask for the total first-year cost in writing.
No UK phone support. Email-only support from a different timezone when your invoicing goes down on a Friday afternoon is not fun.
No free trial. Any decent CRM lets you have at least 14 days to kick the tyres.
You can’t export your own data. If your customer list is locked in their database with no CSV export, you don’t own your business — they do.
Per-user pricing with no team cap. Fine for two engineers. Crippling at ten.
“Custom pricing — book a demo”. Usually means it’s expensive and they want to qualify you before they tell you.
No native UK VAT handling. Sounds basic. You’d be surprised.

Same logic applies to your website and your review system — see our piece on tradesman website mistakes and the guide to getting more Google reviews if you’re tightening up the rest of your setup at the same time.

Off-the-shelf vs custom-built — when each makes sense

Honest answer: off-the-shelf wins for about 90% of plumbing businesses. ServiceM8, Tradify, Commusoft and the rest exist because most plumbing workflows are similar enough that one product can serve thousands of firms. Don’t reinvent the wheel if a £35/month tool does the job.

Custom-built only really makes sense when:

You’re above roughly £500k annual turnover
You run multiple trades under one roof (plumbing + electrical + renewables, say) and existing CRMs force you into separate systems
You’ve got a workflow that’s a genuine competitive advantage — bespoke maintenance contracts, weird subcontractor arrangements, a referral programme no off-the-shelf tool handles
You’re paying so much in per-user fees that a one-off build pays back in 18 months
You’ve already tried two off-the-shelf options and outgrown both

Full disclosure — building custom CRMs for trades is one of the things we do at Auto Ascension, alongside the websites and engagement systems we put together. But we’d genuinely send you to ServiceM8 or Commusoft first if that’s the right fit for your size. There’s no honour in selling someone a £20k build when a £35/month app would have done it.

If you’ve outgrown off-the-shelf and want to talk about a custom-built CRM that actually fits how your firm works, that’s a conversation worth having. If you’re under five engineers, save your money and pick one of the five above. And while you’re tightening up the business side, our guide to email marketing for tradesmen covers what to do with the customer list once your CRM is finally collecting it properly.

Pick the smallest tool that solves your actual problem. Use it for a year. Then revisit. That’s how this is supposed to work.
