Underfloor heating has become one of the most popular choices for new builds and renovations across the UK. But the success of any UFH system depends heavily on one thing most people overlook: the screed layer. Get it wrong, and you end up with cold spots, uneven floors, and a heating system that never performs the way it should.
Liquid screed has quickly become the preferred option for UFH projects because it flows around pipes evenly, conducts heat efficiently, and cuts installation time in half. The catch? Pouring it by hand is slow, messy, and inconsistent. That is where professional pump hire comes in. At Easypump Concrete Ltd, we provide reliable liquid screed pump hire across London, Hertfordshire, Bedfordshire, Buckinghamshire, Essex, and Northampton, helping homeowners and contractors get a perfect pour every time.
What Is Liquid Screed and Why Does It Work So Well With Underfloor Heating?
Liquid screed, sometimes called anhydrite or calcium sulfate screed, is a free-flowing material that gets pumped directly onto a prepared floor. Unlike traditional sand and cement screed, it self-levels as it settles, filling every gap around your underfloor heating pipes without leaving air pockets behind.
This matters because air pockets act as insulators. They block heat from reaching the surface evenly, which means cold spots and wasted energy. Liquid screed wraps tightly around each pipe, creating a solid thermal mass that distributes warmth consistently across the entire floor.
It can also be applied thinner than traditional screed, typically around 45-50mm over UFH pipes compared to 65-75mm for sand and cement. A thinner layer means faster heat-up times and lower energy bills over the life of the system.
Why Hire a Liquid Screed Pump Instead of Doing It Manually?
You could technically pour liquid screed by hand using buckets and wheelbarrows. But on any project bigger than a cupboard, that approach falls apart quickly. Here is why pump hire makes more sense:
- Speed. A screed pump can cover 100+ square metres per hour. A full house pour that might take two days by hand gets done in a single morning.
- Consistency. The pump delivers a steady, controlled flow, so you get uniform depth across the whole floor without guesswork.
- Less labour. You need fewer people on site. The pump does the heavy lifting, which keeps your labour costs down.
- Cleaner site. Screed gets pumped through a hose directly to where it is needed. No trailing wheelbarrows through hallways or up staircases.
- Better access. Need to reach the second floor of a townhouse or a room at the back of a tight extension? The hose runs wherever you need it, even in spaces where a mixer truck could never go.
At Easypump, tight access pumping is one of our specialities. We regularly work on projects where space is limited, and our operators know how to set up efficiently without disrupting the rest of the site.
How Does the Liquid Screed Pump Hire Process Actually Work?
If you have never hired a screed pump before, the process is more straightforward than you might expect. Here is a typical rundown from start to finish.
Before the pour, your underfloor heating system needs to be fully installed, pressure tested, and signed off. Insulation boards should be down, perimeter edging strips fitted, and any expansion joints marked out. Your screed supplier will usually confirm all of this before delivery.
On the day, the Easypump team arrives and positions the pump vehicle as close to the property as possible. The operator runs a hose from the pump into the building, sometimes over considerable distances or up multiple floors depending on the layout.
During the pour, screed gets pumped at a controlled rate while the operator manages flow and placement. Once an area is filled, a dapple bar is used to remove any surface air and help the screed settle to its final level. The self-levelling properties do most of the work, but a quick pass with the bar ensures a smooth, even finish.
After the pour, the screed needs time to cure. Typically, you are looking at about one day per millimetre of depth for the first 40mm, then two days per millimetre after that. Your screed supplier will give you specific guidance based on the product used.
What Size Projects Can a Liquid Screed Pump Handle?
One of the biggest advantages of pump hire is that it scales to fit the job. Whether you are screeding a single room in a kitchen extension or an entire floor of a commercial office building, the equipment handles it.
Domestic projects we commonly work on include:
- House extensions and conservatories
- Full ground-floor renovations
- New build homes with underfloor heating throughout
- Garage and outbuilding conversions
On the commercial side, Easypump has experience with larger installations such as apartment blocks, school buildings, retail fit-outs, and office refurbishments. The process stays the same. The only difference is scale.
Things to Think About Before You Book
A little preparation goes a long way when it comes to liquid screed pump hire. Before you pick up the phone, run through this quick checklist:
- Is your UFH system pressure tested? The screed supplier will not pour over a system that has not been tested and holding pressure.
- Is there access for the pump? You will need space for the vehicle to park and a clear route for the hose into the building.
- What is the weather forecast? Liquid screed should not be poured in freezing conditions. If temperatures are dropping below 5°C, it is best to reschedule.
- Have you coordinated with other trades? Once the screed is down, nobody should walk on it for at least 24-48 hours. Make sure electricians, plumbers, and plasterers know the schedule.
- Do you know the area in square metres? Your screed supplier will need this to calculate volume, and the pump hire team will use it to estimate time on site.
Getting these details sorted before booking saves time on the day and avoids costly delays.
