Screw piles wind into the ground like giant corkscrews and can be loaded the moment they stop turning. No spoil, no wet concrete, no waiting — ideal for garden rooms, decking, modular buildings and lightweight extensions.
How screw piles work
A screw pile is a steel shaft fitted with one or more helical plates. An excavator-mounted torque head rotates the pile into the ground, and the torque required to turn it gives a live, measurable read-out of its load capacity. When the target torque is hit, the pile is proven — install the bracket or beam and start building.
Why homeowners and builders like them
- Instant loading — no concrete cure time, so the frame can go up the same day.
- No spoil — nothing is excavated, so nothing needs carting away.
- Clean and quiet — minimal disturbance to lawns, patios and neighbours.
- Reversible — piles can be unwound and recovered, useful for temporary structures and light-touch planning situations.
- All-weather — installation carries on in conditions that would stop a concrete pour.
What screw piles are best for
The modern garden office is the classic screw pile job: fast, tidy, and no concrete lorry on the drive.
Level, rot-proof support on sloping or soft gardens without digging out.
Repeatable, certified capacities suit factory-built structures perfectly.
Commercial fixtures that need dependable foundations, fast.
The honest limits
Screw piles are brilliant within their lane, and we will tell you when your project sits outside it. Very heavy structures, dense gravels, ground with obstructions or shallow rock all push towards mini piling instead. Our site assessment settles the question before any money is spent — and because we install both, you get the right recommendation rather than the convenient one.
Cost guide
Installed screw pile prices typically run from around £150 to £350 per pile on domestic work, depending on size, depth and access. A garden room on 6 to 10 piles is often founded for £1,500 to £3,000 — and usually finished within a day.

Frequently asked questions
What are screw piles?
Screw piles are steel shafts with helical plates that wind into the ground like a corkscrew, using an excavator-mounted torque head. Torque readings during installation confirm the load capacity of every pile.
What are screw piles used for?
They are ideal for garden rooms, decking, raised terraces, modular and timber-frame buildings, signage and lightweight extensions. Because they can be loaded immediately, there is no waiting for concrete to cure.
Can screw piles be removed?
Yes. Screw piles can be unwound and recovered, which makes them a good fit for temporary structures and sites where a fully reversible foundation is a planning advantage.
Do screw piles work in clay?
They perform well in most North West clays and granular soils. Very dense gravels, obstructions or shallow rock can limit them, which is where our site assessment tells us whether a screw pile or a mini pile is the better tool.
