Missed calls. Quotes written at night. Follow-ups that slip. Invoices left unchased. FlowState gives plumbing and heating businesses one clear automation system that keeps every job moving from first enquiry through to the annual service reminder.
Most plumbing and heating businesses are not short of enquiries. The real problem is what happens next, when calls, quotes, job updates, invoices and review requests begin slipping through the cracks.
Too much of the business is still living in your head.
Quotes to send. Customers to chase. Payments to follow up. Reviews to ask for. When all of that sits in your head, inbox or WhatsApp, it is easy for things to get missed.
FlowState turns those repeatable steps into automated follow-ups, reminders and customer messages, so quotes, payment chases and review requests happen without you having to remember every time.
FlowState builds your complete ServiceM8 setup around the way your plumbing and heating business actually works, connecting each stage from new enquiry to annual service reminder.
Explore how FlowState handles bookings, calls, quotes, updates, payments and reviews inside one joined-up automation system.
One booking, and the whole conversation looks after itself.

Before FlowState, I ran a plumbing and heating business for nearly 10 years. I know what it feels like when calls, quotes, engineers, payments and customers all need your attention at once.
As the business grew, I built my own ServiceM8 system to take the pressure off. It automated the follow-ups, reminders, customer messages and job steps that used to rely on me remembering them.
FlowState is the result of that work. A system built in a real plumbing and heating business, then refined across hundreds of firms across the UK.
From enquiries and quotes to payments, reviews and annual service reminders, FlowState gives you the tools, setup and support to keep every step moving.

Your ServiceM8 account configured for the way plumbing and heating jobs actually run, with the right settings, stages, templates and business details already in place.

Engineers can complete a simple survey, build a clear price and send a professional proposal without starting from scratch every time.

Customers get the right messages at the right time, from booking confirmation to payment follow-up and review request, without you having to send every update manually.

FlowState connects the steps that usually get missed, from new enquiries and handovers to reminders, follow-ups and internal tasks.

Heating-specific forms, certificates, workflows and reminders designed around the jobs your business actually handles.

You get guidance on how the system works, how to use it properly and how to get it embedded into the way the business runs.
"I used to work long hours and struggled getting paid. Since I started using ServiceM8 I've got my time back, I'm winning more jobs than ever before and now get paid before I leave the customer's house."
"I used to take home so much stress from being unorganised. Then I found ServiceM8 and now all that stress has gone. My customers now pay me via a link I send them on a text. ServiceM8 has been a game changer."
"FlowState was a game changer for me. I was able to quote while at the jobs so no more late evenings. I've also been able to get more reviews which has helped me secure more work."
"FlowState ticked all the boxes. We are getting money in faster which has helped our cashflow. Our quote conversion rate has also shot up. I would recommend it to anyone."
Real reviews from business owners who have had FlowState built, set up and working inside their business.
FlowState is used by plumbing and heating businesses across the UK to improve how jobs, messages, follow-ups and reviews are managed. These figures show the combined Google review data from businesses running on FlowState systems.
When the customer journey is organised, customers are easier to keep updated, reviews are easier to request and repeat work is easier to build.
FlowState works best for plumbing and heating businesses that are ready to stop relying on memory, inboxes and WhatsApp to keep jobs moving.

No. ServiceM8 is the engine. We build the whole operating system around it: your job stages, quoting, forms, automations and follow-ups. The setup is the smallest part.
Good, you're halfway there. Most owners use a fraction of what it can do. We restructure how it's set up and used so it actually runs the business, not just stores jobs.
Yes, because it's built around clear job stages and repeatable steps, not a manual nobody reads. Whoever picks up the phone or turns up on site just follows what's in front of them.
No. It won't bring you new enquiries. It makes sure the ones you already get are captured, quoted, followed up, booked, invoiced and reviewed, instead of leaking away.
No. That's the point of the package: we do the technical work. If you can use a smartphone, you can run this system. Your team follows the job stages on screen, and the automations do the rest in the background.
ServiceM8 is the job management app the system runs on. It handles jobs, diaries, quotes, invoices and customer messages. You don't need it already. We'll set your account up as part of the package, and if you're new to ServiceM8 you can claim their £1,000 setup rebate too.
ServiceM8 plans are billed by usage and start small, from around £7 a month for a one-man band. Most established heating businesses land between £25 and £100 a month depending on job volume. That goes to ServiceM8, not us. There are no ongoing fees to FlowState.
Most businesses are up and running within 2 weeks of their onboarding call. We do the build, you review it, and we train you and your team on how to run it.
An onboarding call, a review of the build, and the training. Beyond that, we do the heavy lifting. Most owners put in a few hours in total.
Yes. Customer names, contact details and addresses can be imported into ServiceM8, so you're not starting from an empty system. We'll cover exactly what to bring across on your onboarding call.
Yes. Choose iwocaPay at checkout to pay monthly, from £295.43 a month including VAT at 3.33% per month representative. You get the full system built now, and spread the investment.
If you're new to ServiceM8, they credit £1,000 back as 50% off your monthly subscription until it's used up. It's claimed within 60 days of subscribing, and it effectively brings your net investment down to around £1,395 + VAT. We'll point you at the claim as part of onboarding.
One extra boiler install usually covers it. The system pays for itself through quotes that get followed up instead of going cold, invoices that get chased automatically, and reviews that bring in the next customer. Then it keeps paying, every month, for years.
The opposite. When you're on your own, you ARE the office, and every hour of admin is an hour off the tools or out of your evening. The system does the chasing, confirming and reminding, so you can just do the work.
No, it makes them dramatically more effective. Guided call handling means anyone can price and book jobs confidently. The chasing and reminding happens automatically, so your team spends time on customers, not paperwork.
Then you'll get more from this, faster. Most businesses using ServiceM8 barely scratch the surface. We rebuild your setup properly: job stages, quoting, automations, forms and follow-ups, so it runs the business rather than just storing jobs.
Training for you and your team is included, plus ongoing help when you need it. You're not left with a login and a goodbye. If something needs tweaking as your business changes, we're there.
The system is proven across hundreds of UK plumbing and heating businesses, and we only take on businesses we're confident it will work for. That's what the free call is for: we'll tell you honestly, before you spend a penny, if it's not the right fit.
