Every plumber carries a pipe cutter, and most carry more than one. A clean, square cut on 15mm or 22mm copper is the difference between a capillary joint that runs first time and one you are redoing on your knees under a floor. A hacksaw can do it, but a decent cutter is quicker, leaves no swarf in the pipe and gives you a burr you can ring off in seconds.
The choice is wider than it looks. You can buy a compact pipe slice for tight spaces, a traditional rotary cutter that handles a range of sizes, or a close-quarters model that fits between joists and existing pipework. We checked current Amazon UK listings for the cutters that trade users actually buy, with the prices and review counts shown at the time of writing.
Prices and stock move, so treat the figures below as a guide and check the box under each review for the live price.
Quick Verdict
For most plumbers the Monument Autocut 1715C is the best first buy: it is a proper trade-brand pipe slice at £13.59 with close to 1,000 reviews. If you cut 22mm regularly, add the Rothenberger Pipeslice. If you want one tool that covers a range of sizes in one go, the Rothenberger 35 PRO or Ridgid 35S are the ones to look at.

What to Look for in a Copper Pipe Cutter
Pipe Slice or Rotary Cutter
A pipe slice is a compact, lightweight cutter that clamps on and rotates around the pipe, often sized for a single diameter. It is quick and light, and it lives in a pocket. A traditional rotary cutter has a screw-feed wheel and rollers and handles a range of sizes, which makes it more flexible but bulkier.
Size Range
Most domestic work is 15mm and 22mm, with 28mm and 35mm showing up on larger heating systems. Decide which sizes you cut every day. A 15mm slice is probably the single most-used cutter in a van, and a 22mm one comes second.
Close Quarters Access
If you are working between joists, behind a boiler or along a wall, a cutter that needs a full rotation of clearance will frustrate you. Close-quarters models and pipe slices need far less room around the pipe.
Spare Cutting Wheels
The wheel is the consumable part. Buying a brand with readily available replacement wheels means a worn cutter costs a few pounds to revive, not a full replacement.
How to Choose a Copper Pipe Cutter
Match the Tool to the Work
For new-build and first-fix work you want speed and repeatability, so a pipe slice in each of the two main sizes is hard to beat. For service and maintenance you meet awkward spots more often and a close-quarters cutter earns its place.
Cut Square, Deburr Always
Whatever you buy, a square cut is down to technique as much as the tool. Let the wheel bite gradually, do not force the feed, and deburr the inside and outside of the cut. A burr left inside the pipe catches debris and can cause noise and flow issues.
The Best Copper Pipe Cutters
Monument Autocut 1715C 15mm
The 1715C is the pipe slice many plumbers start with. It is sized for 15mm copper, has the Monument name behind it and costs £13.59. With 972 reviews at the time of writing, it is also one of the most proven options on Amazon UK.
Because it is a dedicated 15mm tool, it makes fast, square cuts without the fiddle of adjusting a screw feed. Replacement cutting wheels are easy to find, so it keeps going long after a cheap import has gone in the bin.
Pros: Trade-brand quality, quick to use, low price, proven review record.
Cons: Only cuts 15mm, so you need a second tool for 22mm.
Best for: Anyone who does regular 15mm first and second fix work.
- Access to cutting copper pipes in awkward places
- It will only cut the exact size of copper pipe
- Not for use on stainless steel
- Cuts in one direction

Monument Autocut Twin Pack 15mm and 22mm
If you know you need both main sizes, the Monument twin pack gives you the 1715C and its 22mm sibling in one purchase. It costs £36.25 and has 53 reviews.
You pay a little more than buying two singles, but the pack is neat for a new apprentice kit or a gift. If you already own a 15mm, buy the 22mm separately.
Pros: Both main sizes, trade brand, simple to use.
Cons: Higher outlay than a single cutter; fewer reviews.
Best for: Newly qualified plumbers building a first kit.

It is bulkier than a pipe slice and needs more room around the pipe, but the flexibility is the point. If you work on larger commercial heating, it is an obvious companion to your slices.

FAQs
What size copper pipe cutter do I need?
For most domestic plumbing you need a 15mm and a 22mm cutter. If you work on larger heating systems, add a rotary cutter that goes up to 35mm.
Are cheap pipe cutters any good?
Some are fine for occasional use, but trade-brand cutters keep their wheels sharp longer and replacement wheels are easy to buy. For daily use the extra few pounds is worth it.
Pipe slice or rotary cutter?
A slice is faster and lighter for repetitive cuts on one size. A rotary cutter is better when you meet several sizes and want one tool.
Can I cut stainless steel or plastic with a copper cutter?
Not with a copper cutter. Use a cutter designed for the material, as the wheel and pressure are different.
How do I get a square cut?
Tighten the cutter gently, rotate smoothly, and keep the cutter square to the pipe. Always deburr the cut before making a joint.
Final Thoughts
A good copper pipe cutter is a small spend that pays back on every job. If you buy only one thing from this list, make it the Monument Autocut 1715C for 15mm, and add a 22mm slice when you need it.
If you work in tight spaces, the Ridgid 103 is a cheap second tool, and if you want a cutter that will last a career, the Ridgid 35S is the one to save for. Whatever you pick, check the live price in the box before you buy.
