You get three quotes back for an underfloor heating job. One is noticeably cheaper than the others. The temptation is obvious: take the win, protect your margin, move on.
But before you do, it’s worth delving into the detail: what exactly have you been quoted?
Underfloor heating is one of those trades where the gap between quotes can be wide – sometimes surprisingly so. And unlike a straightforward material swap, the reasons behind that gap aren’t always visible until you’re mid-install, running short on panels or pipe, and having to explain to your customer that the install won’t be completed on time.
UFH quotes should, in theory, be easy to compare. But in practice, they rarely are.
Some suppliers quote a flat project price with a list of components. Others itemise in detail. Some spec panels that only cover the “heated area,” leaving awkward gaps that still need to be filled to bring floors up to level. Others quote wall-to-wall coverage for a flat level floor, because that’s what a best practice installation looks like.
Material allowances vary significantly between suppliers too. Industry-standard wastage on materials such as floor panels and pipe is typically around 10% – enough of a buffer to account for real-world layouts, cuts, and the small inefficiencies that come with any live job. Quoting light on materials might win a supplier the first job, but it transfers the onsite headaches discussed above onto the installer. The question is: is it worth it?
It’s also worth paying attention to product spec. From panel materials, to pipe type and quality, these things aren’t interchangeable, even when a quote makes them look equivalent. Lower-spec components might not stand out on initial glance but they matter when it comes to system performance, longevity, and what you’re putting your name to.
Warranties are often a point of differentiation too.
Here’s the scenario no installer wants: your install is underway, the screed is booked and other trades are scheduled around your install, and you realise you’re short. Not by much, but enough that you can’t finish.
Not only is a retrospective order going to take time to get to site, but you’re now in a difficult position with your customer. You either absorb the cost of extra materials/delivery to protect the relationship, or you have a difficult conversation about an invoice that’s bigger than what you quoted. Neither option is good.
This isn’t a hypothetical. It’s what happens when a quote is built to win the job rather than to do the job properly.
The real cost of a cheap quote isn’t always visible at the point of ordering. It shows up in delays, in awkward client conversations, in time spent chasing suppliers, and sometimes in margin that quietly disappears because you couldn’t reasonably pass the extra cost onto your customer.
Transparency matters here. A properly constructed UFH quote shouldn’t leave you guessing. It should tell you exactly what you’re getting, line by line, with individual line values; not a lump sum that bundles everything together and makes comparison difficult.
It should include the right system for the application: whether that’s a wet screed system, a low-profile system for retrofit, or something engineered around the specific heat loss of the space.
It should account for proper panel coverage, appropriate wastage, and pipe runs designed to deliver an efficient, balanced system – not just enough to technically heat the floor.
The best quote is the one that allows you to finish the job on time, to a high standard, without unwelcome surprises. That might still be the cheapest quote. But it might not.
Suppliers worth their salt will always be willing to walk you through their quote line by line, and be transparent about where they’ve made specification decisions and why.
At Trade Underfloor, our quotes are fully itemised – every component, every line, with individual values – because we think that’s what professional installers expect. We spec for full wall-to-wall panel coverage, include appropriate wastage, and design systems to perform efficiently, not just to hit a price point.
We’re also happy to look at any competitive quote alongside ours. If you want to understand what’s different and why, we’ll talk you through it honestly. And if a quote is genuinely like-for-like, we’ll guarantee to beat it – and include a free system design as part of that.
We’re not in the business of winning jobs at any cost, we want to build value-led partnerships and be a reliable, trusted UFH supplier to professional installers. That means using our experience to offer the best advice and solutions.
If you’ve got an UFH project coming up and want to understand your options properly, get in touch. We’re always happy to talk through the detail.
