Why this tool matters
A heat gun is one of those tools that sits unused for months and then, when you need it, nothing else will do. Stripping old paint off skirting, bending plastic pipe, shrink-wrapping cable insulation, softening adhesive under vinyl flooring — every trade ends up needing one sooner or later, and the difference between a £15 DIY gun and a £150 trade model is significant enough to matter.
Electricians use them for heat-shrink terminations; plumbers for thawing frozen pipes and forming plastic pipe; painters for stripping old gloss; decorators for drying joint compound. In this guide we compare the best heat guns available in the UK in 2026, covering basic domestic units, trade-grade digital models, and cordless options for jobs where there is no power at hand.
What to look for
Before spending money, here are the key features that separate a professional-grade pick from a DIY-shelf disappointment:
- Temperature range: Entry-level guns offer 350°C to 550°C; trade-grade goes from 50°C up to 650°C with electronic control. Lower end matters for shrink-wrap (needs ~180°C); upper end for stubborn paint stripping.
- Digital vs dial control: Digital displays let you dial in a specific temperature; dial controls give a rough range only. For electrical work where you do not want to overshoot, digital is worth paying for.
- Airflow modes: Dual-speed airflow prevents burning delicate surfaces. Low airflow at high temperature is critical for paint stripping without scorching underlying timber.
- Accessory nozzles: Flat reflectors for shrink-wrap, reducer nozzles for pinpoint heat, glass-protector plates for window frames. Better kits come with 4–6 nozzles in a case.
- Cordless option: A battery heat gun is useful for site work with no power, vehicle work, or quick shrink-wrap jobs. Runtime is short (20–30 minutes) but hugely convenient. Only makes sense if you already have the battery platform.
Top picks: heat guns
Bosch Professional GHG 20-60 Heat Gun
~£110–£160Best for: Best overall, digital trade-grade
Digital LCD display with precise 50°C to 630°C control in 10°C steps, three airflow settings, and a memory function for saving preset temperatures. The trade-standard digital heat gun in the UK — electricians, plumbers and decorators all use it. Comes with four nozzles in the kit version.

~£95–£140Best for: Best for paint stripping
80°C to 650°C digital control, 2000W motor with variable airflow, and a residual heat indicator. The high airflow setting makes it the fastest paint stripper in this comparison — a trim or skirting run that takes half an hour with a cheaper gun is done in under fifteen minutes. Supplied with a nozzle kit.
View on Amazon →DeWalt DCE530 18V XR Cordless Heat Gun (body only)
~£140–£190Best for: Best cordless option
18V XR battery platform, 290°C to 540°C dual temperature settings, around 20 minutes runtime on a 5Ah battery. Only makes sense if you already own DeWalt 18V tools. Ideal for cable shrink-wrap terminations, vehicle work, and site jobs where dragging an extension lead is not practical. No cord drag, which is genuinely excellent for overhead work.

~£35–£55Best for: Best budget / first heat gun
Two-speed dial-controlled 400°C / 600°C settings, 2000W motor, and a cold shoe for overhead use. No digital display and no fine temperature control, but for occasional DIY paint stripping and shrink-wrap work it does the job. A sensible first heat gun at the price.

How to get the best out of it
- Never point it at yourself or others: Exhaust temperatures of 500°C+ cause serious burns instantly, and the metal nozzle holds heat for minutes after shutdown. Set it on a fireproof stand between uses and let it cool before packing.
- Do not use near flammable materials: Dust, cleaning fluid, upholstery and underfloor insulation all ignite at heat gun temperatures. Clear the work area, have a fire blanket or water nearby, and watch for smouldering after you finish.
- Keep the nozzle moving on paint stripping: Static heat on a single spot for more than 3–4 seconds will scorch the timber underneath, and on lead-based paint (common on pre-1980s doors) will produce toxic fumes. Keep it moving in sweeping passes.
- Clean the vent intake regularly: A clogged intake overheats the motor and shortens tool life. Blow it out with compressed air every month of heavy use; every six months for occasional use.
Frequently asked questions
Can I use a heat gun to thaw a frozen pipe?
Yes, carefully, and only on metal pipes — never on plastic (melts) or on pipes near boiler flues or gas fittings. Wrap a cloth around the pipe and work with low heat and constant movement, from the frozen section back towards the tap. Never use an open flame as an alternative — heat gun is the safest DIY option.
Is it safe to strip lead-based paint with a heat gun?
Only with proper precautions. Pre-1980s UK paint likely contains lead. At heat gun temperatures, lead vaporises and is highly toxic. If you must strip paint of this age, wear a fitted P3 respirator, work outdoors or with full room ventilation, vacuum flakes with a HEPA vacuum, and do not allow children or pregnant women nearby. For most homeowners, a chemical paint stripper is safer than a heat gun on older paintwork.
What is the difference between 350°C and 550°C in practice?
At 350°C you are at shrink-wrap and drying temperatures — will not strip paint effectively. At 450°C most modern paint softens and scrapes off. At 550°C older or thicker paint strips rapidly, and adhesives soften instantly. Higher temperature is faster but more prone to scorching — a variable gun with digital control gives you the best of both.
Do I need a cordless heat gun?
Unless you are regularly on-site without mains power or doing a lot of vehicle work, no. Corded heat guns are cheaper, more powerful, and have unlimited runtime. A 30-metre extension reel solves almost every reach problem. Cordless is convenient but a £140+ premium for the capability.
