In-Depth Reviews
1. UY CHAN TS101 Soldering Pen
£76 | Smart portable iron | 65W DC / 45W USB-C PD | Heats in ~5 seconds | 90-450°C range
The TS101 is the iron I recommend to almost anyone doing PCB work in 2026. It takes BC2 cartridge tips that slide into the slim aluminium body, and the short distance between your fingers and the tip gives you genuine control on fine pads. The 65W DC input or 45W USB-C Power Delivery input both drive it hard enough for demanding boards, and it reaches soldering temperature in around five seconds.
One UK buyer who repairs vintage hi-fi says: "I've owned Antex and Weller pencils for years, but the TS101 is the first iron where the temperature on the screen is the temperature at the tip. Reflowing joints on a 1970s amplifier board is suddenly easy." The OLED shows set and live temperature, there's a sleep mode that kicks in when you set the iron down, and the firmware is IronOS-based so you can reflash it for custom behaviour.
The catch is that you need a USB-C Power Delivery charger rated at 45W or higher, and that's not included, so factor that into the price when you're comparing total cost. You also want a spare tip or two, because cartridge tips cost more than the screw-in kind. For the money, though, this is the best soldering iron for PCB work you can buy in the UK right now.
- Heats in about five seconds
- Runs from a USB-C power bank in the field
- OLED shows live tip temperature
- Pocketable aluminium body
- PD charger not included
- Cartridge tips cost more than screw-in bits
- Short silicone cable in the box
2. UY CHAN TS100 Soldering Iron with 2 Tips
£76 | Smart portable iron | 65W | Square OLED | IronOS firmware | Includes 2 tips
The TS100 started the smart pocket iron movement, and this two-tip bundle is still a fantastic buy. It's a 65W iron in a package the size of a marker pen, powered by anything from 12V to 24V DC or a USB-C Power Delivery source with the right adapter. The square OLED shows set temperature, actual temperature, and a live power readout, which is oddly addictive when you're reflowing joints.
The aftermarket tip range for the TS100 is enormous, with fine conical, chisel, and knife-edge bits for every kind of PCB work. One long-term owner writes: "I've had my TS100 for four years and it's still my daily iron. I've replaced the firmware twice, bought a handful of tips, and it's never once destroyed a pad." The stock firmware is good, but the open-source IronOS firmware adds sleep mode, calibration, and boost profiles.
Compared with the TS101, the TS100 has a bulkier square OLED, uses the older screw-in TS100 tip system, and lacks native USB-C PD on the unit itself. The TS101 is the better overall tool. But if you can pick up the TS100 with tips for the same money, it's a genuine bargain that will serve you for years.
- Huge range of cheap replacement tips
- Open-source IronOS firmware
- Live power readout on the OLED
- Two tips included in this bundle
- No native USB-C PD on the unit
- Bulky square OLED versus the TS101
- Power supply sold separately
3. Hakko FX601 Portable Soldering Iron
£154 | Professional pencil iron | 46W | Dial 240-540°C | T18 interchangeable tips | ESD-safe grip
Hakko's FX601 is the iron you find in production repair benches and electronics labs, and it earns that reputation. It's a simple pencil with a dial on the handle that sets temperature from 240°C to 540°C, a 46W ceramic heater that recovers fast between joints, and an ESD-safe grip that won't zap sensitive components. No screen, no menu, just a dial you can set by feel.
The T18 tip system is shared with Hakko's FX-888 station, so the range of interchangeable tips is broad and they're available from UK electronics suppliers. An electronics technician sums it up: "It's not flashy, but it's the most reliable iron I've used in 20 years of bench work. The dial is always where I left it and the temperature never drifts."
You pay a premium for the Hakko badge, and at £154 it's the most expensive pick here. You also get a fairly short cord. But if you do repair work most weeks and want one iron that simply never lets you down, the FX601 is worth every penny. For occasional hobby soldering it's overkill, and you'd be better served by the TS101.
- Dial temperature control with no drift
- ESD-safe grip for sensitive components
- Broad T18 tip range shared with the FX-888
- Fast heat recovery on big joints
- Premium price at £154
- No digital readout
- Short mains cord
4. Antex XS25 Soldering Iron with Silicone Cable
£34 | 25W mains pencil | UK plug | Silicone cable | Screw-in bits | British brand
Antex has been making soldering irons in Plymouth for decades, and the XS25 is the iron generations of British electronics students learned on. It's a simple 25W mains pencil with a slim, light handle, a long flexible silicone cable that doesn't kink, and screw-in bits that cost a couple of quid to replace. For fine through-hole PCB work it's genuinely lovely to use.
The 25W element is enough for pads, headers, and component legs. It's not the iron you want for a heavy ground plane or a big connector, but for the kind of soldering a Raspberry Pi or Arduino project needs, it sails through. An Amazon reviewer notes: "Bought this for my first electronics module at college, and I'm still using it five years later for all my repair jobs."
At £34 it's the cheapest iron in this guide that I'd trust with a PCB, and you can spend the change you save on a decent stand, some good solder, and a set of bits. If you want a no-fuss mains iron that will outlive every gadget you ever solder with it, this is the one.
- British brand with a long track record
- Cheap replacement bits
- Flexible silicone cable
- Light and comfortable for fine work
- Fixed temperature, no dial
- Struggles with large ground planes
- Stand sold separately
5. Weller SP175 Soldering Iron
£61 | 25W mains pencil | UK 3-pin plug | Screw-in replaceable tips | Iconic Weller design
The Weller SP175 is the iron many people picture when they hear the words "soldering iron", and it's been that way for fifty years. It's a 25W pencil with a comfortable heat-resistant handle, a simple screw-in tip, and a UK 3-pin plug that goes straight into the wall. There's no dial, no screen, and nothing to go wrong, which is exactly what a beginner needs.
The screw-in tip system makes swaps trivial, and Weller tips are stocked by every UK electronics retailer, so you'll never hunt for spares. The SP175 reaches working temperature in a couple of minutes and holds it steadily for through-hole work. One parent bought one for their kid's first electronics kit: "Simple enough for a 12-year-old to use safely, and good enough that I borrow it for my own repairs."
At £61 it's pricier than the Antex XS25 for essentially the same specification, and it's a touch heavier in the hand. You're paying for the Weller name and the enormous spare-parts ecosystem. For a first iron that you'll hand down rather than throw away, that's a fair trade.
- Iconic, proven design
- Tips available everywhere in the UK
- Simple and safe for first-timers
- UK plug, no adapter needed
- More expensive than the equivalent Antex
- Heavier handle than modern pencils
- No temperature adjustment
6. YIHUA 928D-III Portable Digital Soldering Iron Kit
£19 | 60W mains kit | Digital temperature display | Temperature stabilization | Stand, tips, solder and sponge included
At £19, the YIHUA 928D-III is the best entry point into electronics soldering you'll find. It's a 60W mains iron with a digital temperature readout, a temperature stabilization circuit that actually holds the set temperature, and a kit that includes a stand, spare bits, a roll of solder, and a cleaning sponge. Open the box and you can start soldering immediately.
The digital display is the standout feature at this price, letting you set and monitor temperature instead of guessing with a fixed-wattage iron. A first-time buyer writes: "Didn't expect much for under £20 but it's got a proper temperature readout and the kit has everything. Built a full synth kit without a single bad joint."
You won't mistake it for a Hakko, and the bits are basic, but that's fine at this price. The 928D-III is the ideal first iron for a kid, a student, or anyone testing whether they enjoy electronics before spending real money. When you outgrow it, upgrade to the TS101 and keep this one as a backup.
- Digital temperature readout at a bargain price
- Complete kit in the box
- Temperature stabilization circuit
- Perfect first iron
- Basic build quality
- Included bits are basic
- No sleep or standby function
7. KAIWEETS 65W USB-C Soldering Iron
£59 | 65W USB-C PD | 80-420°C range | Aluminium alloy body | OLED display | Sleep mode
The KAIWEETS 65W is the budget answer to the TS101, and it's a strong one. It runs off USB-C Power Delivery, so the same 65W charger that powers your laptop runs this iron, and it heats from cold to soldering temperature in around eight seconds. The aluminium body stays cool where you hold it, and the OLED shows your set temperature, the live tip temperature, and the battery level of your power source.
Temperature is adjustable from 80°C to 420°C, which covers everything from delicate SMD work to thicker wire joints, and a sleep mode kicks in after a few minutes of inactivity to save your tips and your power bank. One field service engineer says: "I keep this in my van with a power bank and it fixes more than my old station ever did. Being able to solder anywhere is a game changer for call-outs."
The downsides: the screw-in tip range is smaller than the TS101's cartridge system, and like most USB-C irons you need to supply your own PD charger. For the price, though, it undercuts the TS101 by a significant margin while covering nearly all the same ground. If budget matters more than brand, this is the one.
- Runs from any 65W USB-C PD charger
- Heats in around eight seconds
- Cool aluminium grip
- Sleep mode preserves tips
- Smaller tip range than the TS101
- PD charger not included
- No replaceable cartridge heater
How to Choose Your First Soldering Iron
Temperature control matters more than wattage for beginners. A fixed-wattage iron like the Antex XS25 handles simple pads fine, but when you hit a pad connected to a large ground plane the tip temperature collapses and you get a cold, dull joint. A temperature-controlled iron - whether it is a dial like the Hakko FX601 or a smart iron like the TS101 - holds its temperature under load and gives you repeatable joints while you are still learning.
Check the tip system before you buy. Cartridge systems like the TS101's BC2 tips heat faster and transfer heat better, but they cost more to replace. Screw-in bits are cheaper and easier to find, and for most hobbyists they're more than good enough. Whichever you choose, make sure you can actually buy spare tips in the UK, because a soldering iron with no spare tips is a paperweight.
Think about where you'll use it. If you solder at a bench with mains power nearby, a mains pencil or a full station makes sense. If you want to solder on the sofa, in the garden, or in a workshop without convenient sockets, a USB-C iron powered by a power bank is genuinely handy. The TS101 and the KAIWEETS both handle this brilliantly.
One thing people often forget is ESD safety. For sensitive components like MOSFETs, microcontrollers, and memory chips, an ESD-safe iron such as the Hakko FX601 is worth the extra money. Cheap irons leak voltage through the tip and can damage components you can't see. If you're working on anything expensive, spend the extra.

Frequently Asked Questions
Final Verdict
If you buy one soldering iron for PCB work this year, make it the UY CHAN TS101. It combines cartridge-tip speed, USB-C power flexibility, and genuine temperature accuracy in a package that slips into a pocket, and it's the iron I reach for first on every board I build.
If you're on a tighter budget, the Antex XS25 is the best value in the UK, a proven 25W pencil that's perfect for through-hole work and first kits. And if you earn money with your iron, the Hakko FX601 is the professional choice that will outlast everything else on this list.
Whichever you pick, pair it with decent lead-free solder, a damp sponge or brass wool cleaner, and a fume extractor if you're soldering indoors. The iron is only half the equation, but starting with the right one makes the other half dramatically easier.
