Electric Kilns vs Gas Kilns: Understanding the Best Fit for Your Pottery Needs
Choosing between an electric and a gas kiln is one of the most important calls a UK potter will make. The right answer is rarely "which is better in theory" — it's "which fits your space, your power supply, the work you want to make, and your budget over five years." This guide cuts through the marketing, prices everything in pounds, and is written for the realities of UK home pottery in 2026.

Electric kilns — what they are and who they're for
How an electric kiln works
An electric kiln heats by passing current through resistance elements (kanthal A1 or APM wire) embedded in grooves around the chamber walls. A digital controller — usually a Bartlett, Stafford or Wlogic board — fires the kiln to a programmed schedule. You set the cone, click start, and the kiln does the rest. Modern controllers handle bisque, glaze, lustre and crystalline programmes out of the box.
The advantages most UK potters care about
- Predictable, controllable firings. A digital controller holds temperature within a few degrees of target, every firing. Glaze results become repeatable, which matters far more for a hobbyist than the romance of an open flame.
- Plug-and-play UK installation. Most small kilns up to about 35 litres run from a standard 13A domestic socket. Medium kilns step up to a 16A or 32A commando socket — straightforward for any electrician to install.
- Indoor-safe in a UK home. Electric kilns produce no flame, no combustion gases and no exhaust other than minor wax/glaze fumes that a passive vent extracts. They sit comfortably in a garage, utility room, conservatory or outbuilding.
- Lower running cost than most people expect. A small 13A kiln pulls ~3 kW. A typical 8-hour glaze firing is around 12–18 kWh — roughly £3–£6 at UK domestic electricity rates in 2026. That's far less than a hobbyist usually budgets for.
- Excellent for glaze and decorative work. Electric kilns excel at oxidation firings — bright glaze colours, crystalline glazes, lustres, decals, and modern commercial glaze ranges all want oxidation.
Where electric kilns fall short
- No true reduction atmosphere. If you want celadons, copper reds, shino glazes or wood-ash effects in their classic form, an electric kiln won't deliver them out of the box. Reduction kits exist but are limited and shorten element life.
- Element wear is consumable. Elements last ~150–250 firings depending on temperature. Replacement is straightforward but adds £150–£300 to long-term running costs every couple of years.
- Slower at very high temperatures. Pushing past cone 10 (1285°C) repeatedly is hard work for a domestic-grade element set.
Who an electric kiln is best for
Beginners, hobbyists, anyone working in glaze decoration or low-fire ware, anyone with a domestic-only setting, anyone who wants reliable repeatability, and any potter whose work doesn't depend on reduction effects. That covers the overwhelming majority of UK home potters. Browse our home pottery kiln range for the kilns we actually recommend.
Gas kilns — what they are and who they're for
How a gas kiln works
A gas kiln burns natural gas, propane or LPG through one or more burners directly inside the chamber. Heat comes from combustion; atmosphere is controlled by adjusting the air-to-fuel ratio at the burner and the damper that regulates exhaust flow. Run it lean (more air than fuel) for oxidation; starve it of air at the right moment and you get reduction. The flame is part of the work.
What gas kilns do that electric can't
- True reduction atmospheres. If your work depends on copper reds, celadons, shino, tenmoku, salt or soda effects, you genuinely need a gas (or wood) kiln. Reduction in an electric kiln is a compromise.
- Higher temperatures comfortably. Gas kilns reach cone 11–12 (above 1300°C) without straining. Useful for porcelain, dense stoneware and certain art glazes.
- Variable atmospheric effects within one firing. Skilled potters move between oxidation, reduction, neutral and back across the firing curve to get specific glaze responses. That control simply isn't available on an electric.
Why gas kilns are rare in UK home setups
- Building Regulations and Gas Safe. A gas kiln in a domestic UK setting almost always needs proper combustion air, a flue or chimney, and Gas Safe certification on the installation. That's not impossible but it's expensive — £1,500–£4,000 of additional work before the kiln itself.
- Outdoor or workshop only. Realistically you need a detached outbuilding, a workshop with adequate clearance, or an outdoor location with a roof. Indoor domestic gas kilns are rarely permitted by insurers.
- Higher purchase price. A modest professional gas kiln starts around £3,000 and a serious kiln (140 litres+) is £6,000–£10,000. Self-build is possible but adds significant labour and risk.
- Operator skill matters. A gas firing isn't push-button. You're watching cones, reading the flame, adjusting damper and burner over an 8–14 hour stretch. Beautiful when it goes well; expensive when it doesn't.
- Bottled gas costs add up. If you don't have mains gas access, a single firing on bottled propane runs ~£8–£15 in fuel.
Who a gas kiln is best for
Established potters whose creative work specifically requires reduction, salt or soda firing; production studios making porcelain or high-fired stoneware; potters with an outbuilding or detached workshop and the confidence to manage a manual firing.

Running cost per firing
UK 2026 prices, 30-litre kiln assumed (small home setup):
- Electric glaze firing to cone 6: ~12–18 kWh × ~£0.27 per kWh = roughly £3.20–£4.90.
- Electric bisque firing to cone 06: ~6–10 kWh × ~£0.27 = roughly £1.60–£2.70.
- Gas glaze firing on bottled propane: roughly £8–£15 in fuel for an equivalent load.
- Gas glaze firing on mains gas: roughly £4–£8 if you've got access.

Installation costs
The number that surprises new potters most. For an electric kiln:
- 13A plug-in kilns: usually £0 — they go in any standard socket on its own circuit.
- 16A or 32A commando socket: £150–£400 for an electrician to install on a dedicated radial circuit.
- Hard-wired install / Part P notification: £200–£500 including notification to building control.
- Three-phase supply: £1,500–£10,000+ if you don't already have it. Almost never worth it for a hobby setup.
For gas, expect Building Regulations compliance, a Gas Safe-registered installer, a flue or chimney, and combustion air provision — typically £1,500–£4,000 before the kiln itself.
Lifetime cost over five years
Typical UK home potter doing 2 firings a month:
- Electric setup: ~£1,400 kiln + £200 install + ~£500/year fuel + £200 elements at year 3 = ~£4,100 over 5 years.
- Gas setup: ~£4,500 kiln + £2,500 install + ~£1,000/year fuel + occasional burner servicing = ~£12,000+ over 5 years.
Five-year cost is materially different, even before accounting for time spent firing.
Safety, regulations and home suitability in the UK
Part P electrical regulations
In England and Wales, any new circuit installed in a home is notifiable work under Part P of the Building Regulations. A 32A commando socket on its own circuit for a kiln is typical Part P territory — your electrician should issue an Electrical Installation Certificate and notify building control. Scotland and Northern Ireland have equivalent requirements. Don't try to wire a high-current circuit yourself: insurers will void cover after a fire if work was non-compliant.
Gas Safe and Building Regulations for gas kilns
Any gas appliance burning fuel for heat in a UK setting needs to be installed by a Gas Safe registered engineer. A gas kiln in a domestic outbuilding requires combustion air calculations, a flue, and sign-off. This is not optional — and it's the single biggest reason most UK home potters end up choosing electric.
Ventilation requirements
Even electric kilns produce some fumes during bisque firings (organic burnout from clay) and during glaze firings (volatiles from glaze materials). A passive overhead vent or an active downdraft vent is recommended for any kiln in an enclosed space. Gas kilns need significantly more ventilation — typically a permanent open vent area sized to the burner output.
Insurance and home setup
Most UK home insurers are comfortable with an electric kiln in a garage, outbuilding, or properly ventilated utility room — especially when installed on a dedicated circuit by a qualified electrician. Most are not comfortable with a gas kiln in a domestic setting and will exclude it from cover. Always check before installing either.
How to choose between electric and gas — a UK checklist
Work through these in order:
- Does your work specifically need reduction firing? Copper reds, celadons, shino, tenmoku, salt, soda? If yes, you need gas. If no, skip to step 2.
- Do you have an outbuilding or detached workshop? Indoor gas in a UK home is almost never practical. If your only space is a garage, utility room or conservatory, electric is the answer.
- What's your annual firing volume? Under 40 firings a year tilts heavily toward electric on cost-per-firing. Over 100 firings a year on bottled propane gets expensive — gas with mains supply starts to make sense.
- What's your experience level? First kiln? Choose electric. You'll learn glaze, atmosphere and timing without having to learn flame management at the same time.
- What's your installation budget? If installation is constrained, electric wins by a huge margin.
- What size are you firing? Up to ~150 litres at hobby volumes is firmly electric territory in 2026. Production-scale setups above that, where atmosphere matters, are where gas comes back into the conversation.

Frequently asked questions
Can I run a gas kiln in my UK home garden?
Generally no — not without a permanent outbuilding, a flue, Building Regulations sign-off and Gas Safe certification. A temporary gas kiln in an open garden also typically falls foul of insurance terms. The exceptions are detached outbuildings designed for the purpose, or workshops with proper combustion ventilation. Always speak to your insurer and a Gas Safe engineer before committing.
How much does it cost to fire a small electric kiln in the UK?
At UK domestic electricity rates around 2026, expect roughly £1.60–£2.70 for a small bisque firing and £3.20–£4.90 for a small glaze firing. A larger 60-litre kiln roughly doubles those numbers. Use our kiln cost guide for fuller breakdowns.
Do I need an electrician for a 13A pottery kiln?
For a true 13A kiln plugged into an existing standard socket, no — although we recommend the kiln has its own circuit if possible. For 16A or 32A commando installations, or any hard-wired connection, yes — a qualified electrician should fit it and notify under Part P. The cost is modest and the safety margin is significant.
Can I get reduction firings from an electric kiln?
You can get reduction-style effects with mothballs, sawdust capsules or controlled-atmosphere kits — but the results are inconsistent, hard on the elements, and not the same as a real gas reduction firing. If reduction is central to your work, you genuinely want a gas kiln.
Which is more reliable long-term — electric or gas?
Electric, by a clear margin. Element replacement is the main consumable cost, and digital controllers are very reliable. A typical home electric kiln cleanly fires 10–15 years before any major service. Gas kilns last longer mechanically but require more skilled operation, more maintenance on burners and dampers, and more frequent recalibration. For unattended set-and-forget reliability, electric wins.
The realistic UK answer for most home potters
For the overwhelming majority of UK home potters in 2026, electric is the right answer. It runs from existing domestic power, sits safely in a garage or outbuilding, fires predictably to any cone you'll typically need, and costs a fraction of gas to install and run. Gas is the right answer when — and only when — your creative work specifically depends on reduction, salt or soda atmospheres and you have the space and budget to do it properly.
