Can you make neon signs at home?
Yes, you can make neon signs at home, though the method you choose will largely depend on your budget, skill level, and the look you are going for. Traditional glass neon involves bending gas-filled tubes and is best left to trained professionals, but modern LED neon flex offers a safe, accessible alternative that genuinely replicates the glow.
Is It Hard to Make Your Own Neon Sign at Home?
The difficulty of making your own neon sign depends almost entirely on the technique you are using. Working with genuine glass neon tubes requires specialist training, a glass-working torch, and experience handling gases such as neon or argon; it is a craft that takes years to master and is not realistic for most home hobbyists. LED neon flex, on the other hand, is a far more manageable material that can be shaped, mounted, and wired by anyone with basic DIY confidence.
That said, even LED neon projects carry a learning curve. Getting clean, consistent curves in the flex tubing takes patience, the backing material needs to be sturdy enough to hold its shape over time, and the wiring connections must be secure to avoid flickering or short circuits. Start with a simple word or shape rather than an elaborate design, and the process becomes much more achievable for a first attempt.

What Equipment Do You Need to Make Neon Signs?
Getting the right equipment together before you start is the single most important step in a successful home neon project. For an LED neon flex build you will need: LED neon flex strip (typically 12V), a compatible power supply or LED driver, a rigid backing board such as acrylic or MDF, mounting clips or channel track, a sharp craft knife, cable connectors, and a soldering iron if you plan to join sections. You will also need a pencil, ruler, and a printed or projected template of your design to guide the shaping process.
Beyond the core materials, a heat gun is a useful addition because gentle warmth makes the flex tubing more pliable and easier to bend around tight curves without kinking. If you are cutting acrylic for the backing, a jigsaw or laser cutter produces the cleanest edges, though a hand saw and sandpaper will work at a smaller scale. Sourcing quality LED neon flex from a reputable UK supplier matters more than most beginners realise; cheap flex tends to have uneven light distribution and a shorter lifespan.
| Equipment Item | Approximate UK Cost (2025) |
|---|---|
| LED Neon Flex (per metre) | £4 to £12 |
| 12V Power Supply / LED Driver | £8 to £25 |
| Acrylic Backing Sheet (A2) | £6 to £18 |
| Mounting Clips / Channel Track | £3 to £10 |
| Soldering Iron Kit | £10 to £30 |
| Heat Gun | £15 to £40 |
| Craft Knife and Cutting Mat | £5 to £15 |
| Total Estimated Range | £51 to £150 |
How Much Does It Cost to Make Your Own Neon Sign at Home?
The cost of making your own neon sign at home varies considerably based on sign size, complexity, and the quality of materials you choose. A small LED neon flex sign, perhaps spelling out a short word at around 40 to 60 centimetres wide, can be put together for as little as £50 to £80 once you factor in the flex, a power supply, backing board, and fixings. Larger or more detailed designs, or builds using premium materials such as clear acrylic with edge-lit effects, can push costs closer to £150 or beyond.
It is worth comparing that against the price of buying a ready-made custom LED neon sign from a UK supplier, which typically starts around £80 to £120 for a small piece and rises steeply with size. Making it yourself saves money on labour but costs you time, and you should account for the possibility of needing to replace sections of flex if a bend goes wrong. Buying slightly more flex than you think you need is a sensible precaution on a first build.
| Sign Size | DIY Estimated Cost | Ready-Made Estimated Cost |
|---|---|---|
| Small (up to 50cm) | £50 to £80 | £80 to £120 |
| Medium (50 to 100cm) | £80 to £130 | £130 to £220 |
| Large (100cm+) | £130 to £200+ | £220 to £400+ |
| Glass Neon (professional) | Not DIY-recommended | £300 to £800+ |
Do Neon Signs Need Electricity to Work?
All functional neon signs, whether traditional glass or modern LED flex, require an electrical power source to operate. Traditional glass neon signs run on high-voltage transformers, typically between 2,000 and 15,000 volts, which is one of the key reasons they are hazardous for home construction without professional training. The Health and Safety Executive (HSE) provides clear guidance on electrical safety for anyone working with electrical installations in the UK, and it is worth reading before you begin any wiring work.
LED neon flex signs, by contrast, operate on low-voltage DC power, usually 12V or 24V, making them significantly safer for home use. They plug into a standard UK mains socket via a transformer/driver that steps the voltage down to a safe level, and the flex itself carries no meaningful risk during handling. The running costs are also very low; a typical small LED neon sign draws between 5 and 20 watts, which costs only a few pence per hour at current UK electricity rates.
For anyone planning a more complex installation, such as a permanent wall-mounted sign wired directly into a mains circuit rather than a plug, Part P of the Building Regulations applies in England and Wales. You can find the relevant guidance through the Planning Portal’s electrical safety pages if your project moves beyond a simple plug-in setup.
Making Neon Signs at Home: What You Need to Know Before You Start
Making neon signs at home is a genuinely rewarding craft project, provided you go in with realistic expectations and the right materials. The shift from traditional high-voltage glass neon to accessible LED neon flex has opened the hobby up to a far wider audience, and the results can be strikingly professional when the technique is applied carefully. Planning your design, sourcing quality components, and taking the wiring seriously are the three areas that separate a sign you will display proudly from one that ends up in a drawer.
Patience is the most underrated tool in the process. Rushing the shaping stage or cutting corners on the backing mount tends to show in the finished product, particularly once the sign is lit and any imperfections in the curve or uneven flex tension become visible. Give yourself plenty of time for a first build, keep the design achievable, and treat the initial project as a learning exercise rather than a finished piece.
The UK market for LED neon supplies has grown considerably in recent years, which means quality materials are readily available from a range of online retailers. Whether you are making a sign for a bedroom, a home bar, a small business backdrop, or a personalised gift, the barrier to entry has never been lower. With the right preparation, making neon signs at home is well within reach for most people who enjoy hands-on creative projects.

Can You Make Neon Signs at Home: Frequently Asked Questions
Can I make a real glass neon sign at home?
Genuine glass neon sign making requires high-voltage gas-filled tubes, specialist glass-bending equipment, and years of training to do safely. It is not a realistic home hobby and carries serious risks without professional expertise.
What is LED neon flex and how is it different from glass neon?
LED neon flex is a flexible silicone or PVC strip containing LED lights designed to replicate the appearance of traditional neon tubing. You can learn more about the history and science of neon lighting on the Wikipedia page for neon signs, which covers both the traditional and modern forms in detail.
What voltage does LED neon flex run on?
Most LED neon flex for home use runs on either 12V or 24V DC, supplied through a mains-to-DC transformer that plugs into a standard UK socket. This makes it safe to handle and straightforward to wire without specialist electrical knowledge.
Can I use LED neon signs outdoors?
Some LED neon flex products are rated for outdoor use and carry an IP65 or higher waterproof rating, but not all flex is suitable for external installation. Always check the IP rating on the product specifications before mounting a sign in an exposed outdoor location.
How do I attach LED neon flex to a backing board?
The most common methods are purpose-made mounting clips, adhesive channel track, or small cable ties fed through drilled holes in the backing board. Mounting clips give the cleanest finish and allow for adjustments if you need to reposition sections of the flex.
Can neon signs cause a fire?
LED neon flex runs cool and produces very little heat, making fire risk negligible under normal operating conditions. Traditional high-voltage glass neon carries greater heat and electrical risk, which is why professional installation and maintenance is strongly recommended for genuine glass neon.
How long do home-made LED neon signs last?
Quality LED neon flex typically has a rated lifespan of between 30,000 and 50,000 hours, meaning a sign left on for eight hours a day could last well over ten years. Lifespan is affected by the quality of the flex and driver, so buying from reputable suppliers makes a significant difference.
Do I need planning permission to display a neon sign?
A sign displayed purely indoors requires no planning permission. If you intend to display a sign on the exterior of a building, particularly in a conservation area or on a listed building, you may need advertisement consent under the Town and Country Planning Act; the Planning Portal is the best starting point for checking your specific circumstances.
What is the best backing material for a home neon sign?
Clear or frosted acrylic gives the most professional result and allows the glow to diffuse cleanly, but MDF and plywood are perfectly adequate for decorative indoor signs. Acrylic is more expensive but significantly more durable and visually polished.
Can I cut LED neon flex to a custom length?
Most LED neon flex can be cut at marked intervals, usually every few centimetres, using a sharp craft knife or scissors. Cutting outside these marked points risks damaging the LED circuit inside and rendering part of the strip non-functional.
Is it safe to leave a neon sign on overnight?
LED neon flex signs are generally safe to leave on for extended periods because they run cool and consume minimal power. However, it is good practice to connect the sign via a timer plug rather than leaving it on continuously around the clock.
What tools do I need to bend LED neon flex into curves?
A heat gun set to a low or medium temperature is the most effective tool for making clean, consistent curves in LED neon flex. Without heat, tight bends can create kinks that distort the light output and weaken the flex material over time.
How do I connect two sections of LED neon flex?
Sections of flex are joined using push-in wire connectors or by soldering; soldering produces a more reliable long-term connection but requires basic soldering skills and the correct flux. Ensure the power supply is unplugged before making any connections.
Can I make neon signs at home as a small business?
Making and selling neon signs from home is a viable small business, but you should register your activity with HMRC if your income exceeds the trading allowance, currently £1,000 per tax year. Products sold to the public must also comply with UK product safety regulations, including appropriate electrical safety standards.
