How Are Above Ground Pools Installed?

Thinking of turning your garden into a splash zone? Above ground pools are easier to install than you’d think — just level the ground, build the frame, drop in the liner, and fill! This Swimming Pools UK guide dives into every step (with fewer splinters than DIY usually brings).

Essential Planning and Site Preparation

Let’s get one thing straight: preparation makes or breaks your pool project. And no, you can’t just plonk it anywhere and hope for the best.

This first stage is all about laying the right groundwork — literally.

Choosing the Right Location (Sunlight, Drainage, Level Ground)

Start by choosing a spot that gets some sun, but not too much. You want the pool water to feel warm — not boiling — and the surrounding area to stay cool enough for bare feet.

Avoid setting up under trees unless you're a fan of fishing out leaves every day.

More importantly, check that the area drains well after rain and that the ground is nice and firm. A sloped or squishy surface is a recipe for disaster — or at least a very wobbly pool.

Obtaining Necessary Permits and Checking Regulations

Before you dig or build, check your local council’s rules. In most of the UK, planning permission isn’t needed for temporary pools — but don’t assume.

If you’re near shared fences, listed buildings, or conservation zones, you might need special approval.

It’s better to make a quick phone call now than face a fine (or worse) later.

Clearing and Levelling the Site

Removing Debris and Vegetation

Clear the area like you're preparing a space for a garden party. Get rid of grass, weeds, twigs, and anything sharp.

Use a spade or hoe, and don’t skip this bit — roots can grow back and damage your liner later on.

Creating a Perfectly Level Base (Sand, Concrete, Pavers)

This part takes patience. A small slope might not look like much, but it’ll cause one side of the pool to be deeper than the other — or even collapse.

Use a long spirit level and a straight board to check. Some folks go the extra mile and use patio pavers or a concrete ring for extra stability.

Others lay down sand or a foam pad to cushion the base and protect the liner. Either way, your pool’s future depends on how well you level the ground now.

Assembling the Pool Structure

Here’s where things start taking shape. You’ve got your spot. It’s clean, it’s flat, it’s ready.

Time to build your splash palace.

Laying Out the Bottom Track

Start by laying out the bottom rail — the circular or oval track that forms your pool’s footprint. This will guide the placement of everything else, so make sure it’s exact.

Measure twice. Kick it into place once.

Assembling Wall Panels and Uprights

Next, install the wall panels and vertical uprights that support the frame. Some panels are rolled up like a giant tape measure — tricky, but manageable with a helper.

This part is fiddly, but rewarding. Once those walls are up, it’ll actually look like a pool.

Installing the Pool Liner (Overlap, Beaded)

Now comes the liner — your pool’s inner skin. Spread it out gently, starting from the centre.

There are different types: overlap, beaded, J-hook. Whatever you’ve got, follow the instructions and avoid wrinkles.

Pro tip: Do this on a warm day. The heat helps the liner stretch and fit properly.

Finalising Installation and System Setup

You’re nearly there! Frame built? Liner in? Let’s add water, power up the pump, and turn your backyard into a real-life holiday resort.

Connecting the Filtration System

Installing the Skimmer and Return Fittings

Cut out the pre-marked openings for the skimmer and return fittings. Screw them in tightly — you want water flowing, not leaking.

Use gaskets as directed, and don’t overtighten (trust us on that).

Assembling and Connecting the Pump and Filter

Position the pump and filter close to the skimmer return line. Connect your hoses carefully and check for kinks or loose connections.

Every system’s a bit different, so keep your manual nearby.

Performing Initial Water Fill

Start filling the pool slowly. As it fills, smooth the liner with your feet to prevent wrinkles.

Keep an eye out for bulging walls or leaks. Fix anything before the pool is full.

Adding Essential Accessories and Safety Features

Accessories aren't just extras — they’re part of making your pool safe and user-friendly.

Installing Ladders and Steps

Install your ladder or steps once the water’s high enough. Make sure they’re secure and slip-resistant.

For families, look for models with locking or removable steps.

Setting Up Safety Barriers (Fencing, Alarms)

A pool is fun, but safety comes first — especially if you’ve got little ones or pets.

You might not legally need a fence in the UK, but it’s a smart move. Alarms and covers offer extra peace of mind too.

Initial Water Chemistry Balancing

Once it’s full, test your water using a kit or strips. Balance the pH, add chlorine, and adjust alkalinity as needed.

This first treatment helps stop algae and keeps the water clean. Maintenance starts from day one.

Professional Installation vs. DIY

Let’s be honest — not everyone wants to dig, level, and build. And that’s OK.

When to Hire a Professional Installer

If you’ve got a tricky garden, limited tools, or just prefer to let someone else handle the heavy lifting, call in the pros.

They’ll get it done faster and you’ll usually get a warranty too.

Tools and Skills Needed for DIY Installation

Going the DIY route? You’ll need basic tools: shovel, rake, spanner, level, and patience.

It’s doable — thousands of people do it every year. But plan for a full weekend (or two), especially if you’re new to it.

Importance of Following Manufacturer Instructions

No matter what, follow the manual. Every pool brand has its quirks and shortcuts.

Ignore it, and you might be in for repairs — or worse, redoing the whole thing.

Final Splash: Wrapping It Up

Installing an above ground pool isn’t rocket science — but it does take effort, planning, and a few good cups of tea.

Choose the right spot. Level it well. Follow the steps.

Once it’s all done and your toes are dipping into cool, clear water? Totally worth it.

Your garden just became the neighbourhood's new favourite hangout.
