Float fishing is the foundation of UK coarse fishing. More British anglers have caught their first fish under a float than by any other method, and for good reason: a float gives you instant visual feedback on what is happening to your bait, it works for almost every coarse species in almost every water, and the satisfaction of watching a float disappear on a confident bite never really wears off.
This guide is aimed at anglers starting out or returning after a gap. It covers how to set up a basic waggler float rig on still water, how to read bites, how to strike, and how to find fish on any water you visit.

What You Need to Start Float Fishing
You do not need much. The basics:
Rod: A 12-13ft match rod is the standard starting choice. The length helps with striking and line control. Look for a through-action rod that bends progressively from butt to tip – this cushions the strike on fine hook lengths and plays fish gently without snapping off. Budget rods in the 30-70 range work fine for beginners.
Reel: A 2500-size fixed spool reel with a basic front drag. The drag should be smooth enough to give line under pressure. Nothing complicated needed.
Mainline: 4-6lb monofilament. Monofilament floats and casts well and is easy to handle in cold or wet conditions. Braid is not suitable for float fishing.
Hook lengths: 18 inches to 3ft of lighter line (2-4lb) attached to the mainline via a swivel or loop-to-loop connection. The hook length is lighter than the mainline so that if you snag or the hook length breaks, you lose only the hook and not the float.
Floats: Start with a selection of insert waggler floats in 2BB, 4BB, and 6BB sizes. The number refers to the shot capacity – the amount of weight required to cock (sink down to the antenna) the float. Larger numbers cock with heavier shot, cast further, and suit deeper or windier conditions.
Shot: Sts or shot in sizes 4, 6, 8, 10, and 12. Shot locks the float on the line and adds casting weight. Sizes 8-12 are used as dropper shot near the hook; sizes 4-6 are used as bulk shot closer to the float.
Hooks: Sizes 14-18 for most general float fishing with maggots or casters. Eyed hooks or ready-tied hooks with 2lb hook lengths are both suitable. Barbless is easier to unhook and required on most commercial fisheries.
Bait: Start with maggots. They work on almost every coarse species, they sink slowly to a controlled depth, and they are universally available from tackle shops.
How to Set Up a Waggler Float Rig
The waggler float attaches to the line at the bottom only – through the eye at the base. This is what distinguishes it from a stick float (which attaches at top and bottom and is used on flowing rivers).
Step 1. Thread the mainline through the eye of the waggler float. Lock the float in position using two or three size 4 or 6 shots pinched either side of the float’s lower eye. This anchors the float and provides most of its casting weight.
Step 2. Tie a swivel to the mainline below the float and above the hook length using an improved clinch knot. The swivel prevents line twist and gives you a point to change hook lengths without retying above the float.
Step 3. Attach your hook length to the swivel. Tie your hook to the hook length with an improved clinch knot (or use a pre-tied ready hook length).
Step 4. Set the depth. The float should be set so the hookbait hangs just off the bottom, or lays on the bottom with a tiny amount of slack in the hook length. To find the depth, use a plummet (a small weighted attachment that clips to the hook and sinks to the bottom) to measure the depth of the swim. Set the float to the depth of the swim, then add 6 inches to allow the bait to settle on the bottom, or subtract 6 inches to fish just off the bottom.
Step 5. Add dropper shot. Place one or two size 8-10 shot on the hook length, 6-8 inches above the hook. These help the bait sink through the water and give you control over how quickly it reaches the bottom.

Casting
A float rod is not a distance-casting tool. Most still water float fishing is done at 10-20 metres from the bank. Cast by holding the rod at roughly 45 degrees, releasing the line with a gentle underarm or pendulum cast. The float should land in approximately the same spot each cast to build up loose feed in a tight area.
Before casting: make sure your hook is not tangled around the line. Check the hook length is trailing free below the float before every cast.
After casting: close the bail arm immediately and allow the float to settle and cock (stand upright in the water). If the float cocks but the antenna remains too high, add another small shot. If the float is pulled under immediately, you are either too shallow for the water depth or there is too much weight.
Reading the Float and Striking
Once the float has settled and cocked properly, you are fishing. Watch the antenna – the thin coloured tip above the water.
A proper bite usually shows as one of three things: – The float slides away across the surface (a fish taking the bait and moving) – The float dips under cleanly (a confident take straight down) – The float lifts out of the water (a fish picking up the bait from directly below and swimming upward, reducing the weight on the line)
When to strike: Strike at a definite movement, not a tremble or nervous dip. A fish mouthing the bait and rejecting it looks different from a fish that has taken it confidently. Wait for a clear, continued movement before striking.
How to strike: A short, sharp lift of the rod tip – 30-45cm of upward movement. Enough to tighten the line and drive the hook home, not a huge overhead sweep that snaps the line or drags the float across the water. On fine hook lengths (2lb or below), be gentle – the hook sets with very little force required.
What Fish to Expect
On a typical UK stillwater or slow canal, float fishing with maggots will catch:
Perch – Small perch are often the first fish on any new water. They hit the bait confidently and pull the float away cleanly.
Roach – The classic UK float fishing species. Roach give characteristic lift bites (the float rising and laying flat) because they pick up the bait from below. On canals and park lakes, roach make up a large proportion of the catch.
Bream – On deeper stillwaters, bream feed on the bottom and give pronounced dipping bites. They grow large and fight powerfully for their size.
Tench – Tench give a characteristic bubbling display before the bite – small bubbles rising to the surface near the float where they are rooting in the bottom. The float then lifts and holds before sliding away. One of the most satisfying fish to target on the float.
Rudd – Similar to roach but often feed closer to the surface. If your float keeps lifting and the bites are coming at a mid-water depth rather than on the bottom, switch to fishing shallow.
Finding Fish on Any Water
The mistake most beginners make is casting out to the middle of the open water. Fish are not usually there. They are near structure and cover.
On canals: The shelf on the far side (the ledge where the depth drops off) holds roach and perch throughout the year. The near shelf holds tench and bream in summer. Around moored boats, locks, and bridge supports holds perch and chub.
On park lakes and ponds: The margins around reed beds and overhanging trees hold tench and bream. The clear water beside lily pads holds rudd and tench. Do not fish the open centre – fish the edges.
On rivers: Choose a section with some slack water or a steady pace. Fast, turbulent water is harder to present a float in. The inside of a bend, the downstream side of a bridge, or a steady glide on a bank with some bankside vegetation are better choices than open, fast water.
Feeding the Swim
Float fishing works best when you introduce loose feed regularly to hold fish in the area you are fishing.
Catapult or lob a pinch of maggots (6-12) into the swim every cast. The maggots sink slowly and attract fish from above and below. Do not overfeed – you want to attract fish, not fill them up. Little and often is the rule.
Once fish are feeding, increase loose feed slightly. When bites slow, drop back to minimal feed.
Common Beginner Mistakes
Setting the float too deep. If the bait is dragging on the bottom because the float is too deep for the swim, you get few bites. Plumb the depth accurately.
Striking too hard. A gentle lift sets the hook on fine tackle. A full-arm strike snaps 2lb hook lengths instantly.
Not waiting for a definite bite. Striking at every tremble produces missed bites and a spooked swim. Wait for a clear, confident float movement.
Casting too far. Most fish on still waters are caught at 15-20 metres or less. Casting further makes the rig harder to control and the float harder to see.
Frequently Asked Questions
What is the best float for beginners?
An insert waggler float in 4BB size is the best all-round starting float. It suits still waters and slow canals, casts accurately at 10-20 metres, and shows bites clearly in sizes that work for both roach and larger species. The insert (thin tip) is more sensitive than a plain tip float for shy biting fish.
What depth should I set my float?
Set the float so the bait hangs just off the bottom – typically the depth of the swim plus 6 inches. Use a plummet to find the exact depth. Fish shallow (half the depth) if you are getting no bites on the bottom, which suggests fish are feeding mid-water.
What is the best bait for float fishing?
Maggots are the most versatile and effective float fishing bait for beginners. They work on almost every species, are available from every tackle shop, and can be used as hook bait and loose feed simultaneously. Casters (the chrysalis stage of a maggot) are more selective for larger roach and bream. Bread flake is excellent for roach, chub, and tench and works where maggots are refused.
How do I stop my line sinking between the rod tip and the float?
Sink the line by dipping the rod tip into the water after casting, then winding a few turns of line to tighten the line between rod tip and float just below the surface. This prevents wind drag from pulling the float off line and disturbing the presentation. Keep the rod tip low throughout the session.
What is a hook length and why do I need one?
A hook length is a short section of lighter line (typically 2-4lb) connecting your swivel to your hook. It is lighter than the mainline so that if you snag on the bottom or a large fish breaks you, the line parts at the hook length rather than losing the float and half your mainline. Replace hook lengths when they become frayed, knotted, or after every large fish.
