Pouring concrete sounds simple until you have to get it from the truck to the exact spot you need. That is where pumps come in, and the big question is which one to hire. For a lot of jobs, line pump hire is the smarter, cheaper pick, while a boom pump only earns its keep on bigger, taller sites. So how do you tell them apart? It comes down to access, budget, and how much concrete you are moving. Get the match right, and the pour is quick and clean. Get it wrong, and you pay for power you never use.
Line Pump vs. Boom Pump
Choose a line pump whenever access is tight, the pour is at ground level, and the budget is modest. It uses flexible hoses along the ground, so it fits driveways, slabs, and foundations with ease. Boom pumps only earn their place when you need serious height or very high volume.
When in doubt, weigh access first, then volume, then cost.
What Situations Favour a Line Pump?
Line pumps suit small to medium pours where a truck cannot easily reach. They are cheaper, simpler to set up, and brilliant in tight spaces. For most homes and small sites, line pump hire is all you need.
Tight access sites
Line pumps win on cramped sites. Their hoses snake through gates, alleys, and doorways that a boom truck could never fit. They are the go-to choice for back gardens and terraced streets.
Smaller residential pours
Most home jobs are a perfect match. Driveways, garden slabs, and pool surrounds rarely need a boom pump’s reach. These pours finish quickly without the extra hire cost of a boom.
Budget-conscious jobs
Line pumps cost far less to hire. Hire starts from around £275, while a boom pump usually begins at £650 or more. You also save on setup time and crew, which keeps the day cheaper.
When Should You Avoid a Boom Pump?
Skip the boom pump when its size and cost bring no benefit. On the wrong job, it is expensive and hard to position. It can also block a road or driveway while it sets up.
Boom pumps are the wrong fit when:
- Access is too tight for a large truck to set up.
- The pour is small and does not need high volume.
- No vertical reach is required at all.
- The job is indoors or under a low roof.
This means you would pay boom pump rates for power that sits idle, so a line pump makes more sense.
Site Conditions That Suit a Line Pump
Line pumps thrive on ground-level work and awkward layouts. The hoses go where wheelbarrows and trucks cannot. Few other methods cope so well with stairs and narrow gaps.
They are ideal for:
- Residential driveways, slabs, patios, and pools.
- Interior pours or feeding concrete through a building.
- Sites with obstacles, stairs, or uneven access.
In addition, the hoses can be extended with extra sections, so distance is rarely a problem.
How Do Site Access and Project Size Affect Your Choice?
Access and volume decide the pump every time. Match the kit to the site rather than the other way round.
Pumping distance
Line pumps reach surprisingly far. They can push concrete over 150 metres horizontally, and up to 260 metres vertically with an added hose. That covers almost any home or small commercial plot.
Vertical vs horizontal placement
Horizontal, ground-level pours favour a line pump. Tall, vertical placement is where a boom pump’s arm takes over. For single-storey work, the line pump usually wins outright.
Set up time and site footprint.
Line pumps need little space and set up fast. Boom pumps need room for outriggers and a clear overhead path. Less setup means less labour and a quicker finish.
Cost, Flexibility, and Manoeuvrability
Line pumps usually win on price and ease of handling. They cost less to hire and move into place with little fuss. On a small job, that saving is the difference that matters.
Where a line pump pulls ahead:
- Lower hire cost, often from around £275.
- Faster setup with a smaller crew.
- Hoses that bend around tight corners and obstacles.
Boom pumps offer more reach and speed, yet that power costs more and needs space, so it only pays on the right job.
Line Pump vs Boom Pump at a Glance
Here is how the two compare on the points that matter most. Use it as a quick gut check before you book.
| Factor | Line pump | Boom pump |
| Best for | Small to medium ground pours | Tall or high-volume pours |
| Site access | Tight, restricted spaces | Needs room for a large truck |
| Reach | 150 metres plus with hose | Up to 70 metres via the arm |
| Setup | Quick and compact | Slower, larger footprint |
| Hire cost | From around £275 | From £650 to £1,000 plus |
| Operators | Trained operator included | Trained operator, often a separate fee |
| Best pour type | Driveways, slabs, foundations | High-rise, large commercial slabs |
When is a Boom Pump Still the Better Fit?
Boom pumps earn their cost on big, tall, or fast jobs. The robotic arm places concrete where hoses cannot.
Tall structures
Multi-storey builds need height. The boom arm lifts concrete several floors in one go. Pumping by hand to that height would be slow and unsafe.
Fast, high-volume pours
Big slabs need speed. As a result, a boom pump moves large volumes quickly with fewer hands on site. One steady pour also gives a cleaner, stronger finish.
Large commercial projects
Commercial sites often combine height, volume, and distance. That is exactly where a boom pump pays off. The higher cost is easy to justify at that scale.
FAQs
How far can a line pump reach?
Line pumps can push concrete over 150 metres horizontally, and up to 260 metres vertically with an extra hose. Most jobs use only a fraction of that range.
What jobs does a line pump suit best?
Driveways, slabs, patios, pools, and foundations. Any ground-level pour with tight access is a strong match. If a wheelbarrow struggles, a line pump shines.
How do you decide quickly?
Think access, budget, and pour size. If the site is tight and the pour is low, choose a line pump. If it is tall or huge, go boom.
Bottom Line
Pick the pump that matches your access, budget, and pour size. For most ground-level and tight access jobs, a line pump is faster, cheaper, and easier to handle. Save the boom pump for the tall and high-volume work that truly needs it.
