AvantiGas Business Review: LPG Pricing, Contracts & Off-Grid Energy

AvantiGas is a UK LPG supplier serving off-grid business and domestic customers across England, Scotland and Wales. Based in Derbyshire and part of UGI Corporation, they currently focus on bulk LPG and BioLPG, plus their renewable Essentia (rLG) blend. They previously also supplied mains natural gas and gas cylinders, but those divisions have now been sold — see “Recent Business Changes” below.

They offer comprehensive energy services with competitive pricing and flexible contracts, lasting anywhere from 1 or 3 years. AvantiGas helps businesses through every step of the switching process, from the first consultation and site survey to installation and regular fuel delivery. Their 24/7 emergency call centre is always open for customer support.

Recent customer feedback is mixed. AvantiGas markets attractive tariffs and automatic top-up services, but online reviews have pointed to drops in customer service quality. Their public Trustpilot profile carries a strong overall rating, though business buyers should also check their own contract-specific terms before signing.

Recent Business Changes

AvantiGas’s product range has narrowed significantly over the past three years. Two divisions have been sold off, and the brand now focuses on bulk LPG and renewable LPG variants only.

Mains gas business sold to British Gas (October 2022). British Gas acquired AvantiGas ON Limited, the mains natural gas subsidiary. Approximately 13,000 mains gas business customers were migrated to British Gas by January 2023. AvantiGas no longer supplies mains natural gas to UK businesses.

Cylinder gas business sold to Flogas Britain (October 2025). AvantiGas’s gas cylinder operation was acquired by Flogas Britain. AvantiGas no longer supplies LPG cylinders. The bulk LPG supply business remains under the AvantiGas brand and is the focus of the rest of this guide.

Overview of AvantiGas and Its Business Offering

AvantiGas operates as a major LPG supplier, bringing off-grid energy solutions to businesses across England, Scotland, and Wales. They work with a wide range of sectors and keep a focus on environmental responsibility and professional service.

Company Background and Market Position

AvantiGas holds a strong position in the UK’s LPG market, supplying liquefied petroleum gas through a broad network of distribution centres and two inland gas terminals.

They’re part of UGI Corporation, a big international player in energy distribution. UGI manages energy product distribution, storage, transport, and marketing through its various subsidiaries.

Their UK-based emergency call centre runs 24/7, offering support and aftercare to customers nationwide. This setup helps AvantiGas deliver maintenance and responsive service wherever it’s needed.

AvantiGas focuses on off-grid energy solutions, making them a go-to for areas without mains gas connections. They serve both residential and business customers who need alternatives to traditional energy.

Types of Businesses Served

AvantiGas creates tailored LPG solutions for large businesses in different sectors. They put special focus on manufacturing companies that rely on steady off-grid energy.

They offer several core products:

• LPG bulk gas for large operations
• BioLPG and Essentia (rLG) for businesses aiming to cut CO2 emissions while keeping existing LPG infrastructure
• Aerosol propellant for industrial uses

AvantiGas works with builders and specifiers throughout the UK. These professionals use their off-grid heating and energy solutions for construction projects.

They serve a mix of businesses, from small firms that need bottled gas to big manufacturers using bulk LPG. AvantiGas adapts its services to fit each business’s specific requirements.

Core Values and Environmental Commitment

AvantiGas says their approach is all about service and relationships, not just selling a product. They promise safe, efficient, and friendly delivery every time.

They see LPG as a clean and efficient energy solution. This focus on the environment appeals to businesses looking to cut their carbon footprint while keeping energy reliable.

Professional service is a cornerstone for AvantiGas. They stick to strict safety standards, from delivery to ongoing customer support.

They also offer partnership opportunities for businesses in related sectors. Builders and energy specifiers can collaborate, potentially earning extra income through AvantiGas’s off-grid network.

Gas Supply Solutions for Businesses

AvantiGas provides LPG solutions that cover bulk delivery systems with storage tanks, portable bottles for flexibility, and full installation services with ongoing maintenance.

Bulk LPG Delivery and Storage Options

AvantiGas delivers bulk LPG to businesses with high energy needs. This setup works best for companies needing a steady gas supply all year.

They install large storage tanks at business sites. These tanks hold a lot of LPG, so you don’t need deliveries as often. This usually lowers the per-unit cost compared to smaller supply options.

Storage tank sizes:

• Small commercial tanks: 1,000-2,000 litres
• Medium industrial tanks: 3,000-6,000 litres
• Large capacity tanks: 10,000+ litres

They schedule regular deliveries so tanks stay topped up. AvantiGas tracks usage patterns to predict when you’ll need a refill, coordinating deliveries to avoid business interruptions.

LPG Bottles for Business Use

Gas bottles offer a flexible LPG solution for smaller businesses or specific needs. AvantiGas has different bottle sizes to fit various commercial uses.

Standard sizes include 19kg, 47kg, and some specialist options. These portable bottles suit restaurants, workshops, and seasonal businesses. You can order bottles as you need them, without a long-term storage commitment.

Advantages of bottled LPG:

• No installation costs
• Easy to transport and store
• Great for temporary setups
• Quick to get started at new locations

They run an exchange system, swapping empty bottles for full ones. That way, you won’t be left waiting for a refill.

LPG Tank Installation and Maintenance

AvantiGas handles installation from start to finish with their in-house engineers. They take care of everything, from the first site assessment to the final system sign-off.

Their engineers design storage to fit your business needs. Installation covers safety systems, monitoring, and connecting to your existing appliances. They make sure all work follows current safety rules.

Maintenance includes:

• Regular safety checks
• Tank monitoring
• Equipment servicing and repairs
• Emergency breakdown support

They offer financing options for big installations, so businesses can upgrade without a huge upfront payment. Maintenance contracts keep systems running smoothly and safely.

Contract Terms, Pricing, and Competitive Rates

AvantiGas gives businesses a choice of flexible contracts with fixed-term agreements for 12 months or 3 years. Their pricing includes both variable and fixed-rate plans.

Pricing Structures for Businesses

AvantiGas offers two main pricing options. Fixed-term contracts lock in your rate for the contract’s duration.

Variable plans follow market prices, which can go up or down. Some businesses prefer this flexibility over fixed rates.

Fixed-Rate Benefits:

• Protection from price hikes
• Easier budgeting
• Available for 12-month or 3-year terms

Variable Rate Features:

• Prices change with the market
• Possible savings when market prices drop
• More flexibility

They set energy charges at agreed rates for fixed contracts. Variable pricing moves with the market and supplier adjustments.

Contract Lengths and Fees

AvantiGas gives you a choice between 12-month and 3-year contracts.

They offer installation financing with no upfront costs, helping businesses manage cash flow when setting up a new supply.

Contract options:

• 12 months: Shorter commitment, easier to renew or change
• 3 years: More price stability and planning certainty

New customers get a 30-day notice period. You can change your mind within this window without penalties.

Early termination fees might apply if you cancel. The exact terms depend on your contract and how much time is left.

Competitive Rates Compared to Other Suppliers

AvantiGas pitches itself as a competitive option in business energy. Their pricing aims to attract businesses looking for value and reliability.

They compete with other suppliers through flexible contracts and 24/7 emergency services, which go beyond just the price.

Competitive advantages:

• No upfront installation fees
• Flexible contract lengths
• Emergency support
• Focus on greener energy

Rates depend on your business size and usage. It’s a good idea to get quotes and compare AvantiGas with other suppliers before signing anything.

Their rates reflect current market conditions and operating costs. Comparing suppliers is the best way to find the right deal for your business.

Fuel Options: LPG, LNG, and Biomass

AvantiGas offers three main fuel types, giving businesses cleaner choices beyond traditional fossil fuels. Each option comes with its own benefits for different types of operations.

Benefits of LPG Gas for Businesses

LPG is a versatile choice for off-grid businesses. It’s about half the price of petrol or diesel and delivers reliable energy for heating, cooking, and industrial work.

Instant Control and Reliability

You get immediate heat with LPG, and you can control temperatures exactly. That’s handy for operations needing steady temps or quick changes.

Lower Maintenance

LPG burns clean, so there’s less soot and ash compared to oil. That means less daily maintenance and no need for manual fuel handling.

Storage and Delivery

You can store LPG in bulk tanks on-site and pipe it straight into buildings. It’s easier to deliver and store than oil.

Environmental Benefits

LPG emits fewer carbon emissions than coal or oil. It also produces fewer toxic particles, which is good news for businesses focused on the environment.

Liquefied Natural Gas (LNG) and Its Advantages

LNG works best for businesses with steady, high-volume energy needs. Heavy industry and companies that use fuel year-round benefit most from LNG.

Ideal Applications

LNG suits businesses with continuous process work. It’s also great for heating large spaces or water in big facilities.

Cost Efficiency for High Users

If your energy use is steady, LNG can be cheaper than other fuels. The consistent demand makes the investment in LNG infrastructure worthwhile.

Industrial Compatibility

Manufacturers and processing plants often pick LNG since it fits well with their big energy systems.

Biomass and Other Alternative Fuels

AvantiGas also offers renewable biomass and BioLPG for businesses aiming to cut carbon. These alternatives help companies meet regulations and shrink their environmental footprint.

BioLPG Benefits

BioLPG works just like regular LPG but comes with a lower carbon footprint. You won’t need to change your existing LPG equipment.

Renewable Energy Solutions

Biomass fuels come from sustainable sources, helping businesses hit green targets. They offer dependable energy while supporting renewable goals.

Meeting Regulations

Alternative fuels help businesses meet emissions standards, which is only going to get more important as regulations tighten.

Switching to AvantiGas: Process and Support

AvantiGas has a five-step process for businesses switching from oil or coal to cleaner fuels. They can finance installation costs, so you don’t need to pay upfront. Their turnkey solutions cover fuel supply and project management.

Fuel Conversion and Installation Steps

AvantiGas uses a five-step process for businesses converting to LPG or biomass.

Step 1: Initial Contact

You can reach AvantiGas by phone, email, or through their website to talk about your energy needs.

Step 2: Site Survey

They’ll do a detailed survey of your premises to figure out what you need.

Step 3: Installation Planning

AvantiGas will plan the installation, aiming to keep disruption to your business to a minimum.

Step 4: Fuel Delivery

They’ll organise the first fuel delivery to your new system.

Step 5: Completion

Once the switch is finished, you can start using your new energy setup and (hopefully) save some money.

They can finance installation, so you won’t have to pay upfront. This makes it easier for businesses to switch to cleaner fuels.

Business Energy Supply Switching Process

Switching to AvantiGas for bulk LPG supply starts with a request form on their website covering your energy requirements, site details and tank-siting needs. Note: AvantiGas no longer supplies mains natural gas (sold to British Gas in 2022). For mains gas, contact British Gas Business directly.

After you accept their offer, AvantiGas manages the whole switching process, including dealing with your old supplier and handling the changeover.

They offer competitive rates and install AMR (Automatic Meter Reading) devices for business customers. These meters send readings directly to AvantiGas and update your online account.

Contract options:

• Fixed-term: 1 or 3 years with standing charges
• Variable: Flexible terms
• Tariff rates: 30-day notice for customers not under contract

If you’re moving premises, AvantiGas needs some advance notice and a final meter reading. You can submit changes online or call 0808 208 0000.

Support with Regulatory Compliance

Switching from oil or coal to LPG or biomass helps businesses meet regulations and cut carbon emissions. AvantiGas supports companies in staying compliant with environmental standards.

Their biomass fuel is 100% carbon neutral, which is handy for businesses looking to lower their impact. LPG also has fewer toxic particles than traditional fuels, making it easier to meet air quality standards.

AvantiGas runs a 24/7 emergency support line, so businesses can keep things running and stay compliant.

Aftercare includes:

• Account management
• Regular contract reviews
• Equipment warranties
• Annual system inspections

They offer BioLPG to both business and home customers, supporting decarbonisation goals. This renewable fuel helps businesses work towards net-zero while keeping energy reliable.

Customer Service and Business Experience

AvantiGas keeps a 24/7 emergency call centre running and offers different support channels for business customers. Customer feedback is mixed, with service quality varying quite a bit depending on where you look.

Quality of Customer Service and Support

AvantiGas runs a 24/7 emergency support line through their call centre. This covers maintenance, equipment faults, and urgent gas supply issues.

Business customers can get in touch by phone, email, or online forms on the website. It’s not hard to find a way to reach them.

Customer feedback paints a mixed picture:

• Some people mention helpful and professional engineers.
• Others say service standards have slipped lately.

Emergency calls sometimes get a response in as little as four hours. That’s not bad, though it does depend on where you are.

AvantiGas assigns account managers to larger business clients. These managers look after contract reviews and keep the relationship ticking over.

The online portal lets businesses manage their accounts themselves. You can check bills, send meter readings, and make payments there.

Staff training seems a bit hit and miss, according to reviews. Some staff come across as friendly and well-informed, but others don’t seem as focused on the customer.

Reliability of Supply and Delivery Performance

AvantiGas uses forecasting tech to schedule bulk LPG deliveries for business customers. This helps them avoid running out of gas.

Key reliability features include:

• Automatic top-up when gas runs low
• Telemetry-equipped LPG tanks for usage monitoring and automatic top-up
• Direct supply for LPG bottle customers

They’ve set up storage and distribution sites across the UK. This network helps them serve both business and household customers.

Delivery performance depends on the type of fuel and where you are. Bulk LPG users usually get steadier service compared to those relying on bottles.

They offer a 24/7 emergency response for critical supply problems. Engineers can get sent out, but how fast they arrive depends on where you are and how busy things are.

Contract customers usually get priority over those on standard tariffs. Fixed-term deals often come with guaranteed service levels and delivery promises.

Handling Complaints and Feedback

AvantiGas has a set complaints process with clear timelines. Customers can send complaints through the website, by email, or post.

Here’s how it works:

• They acknowledge complaints within 48 hours.
• If they can’t fix it straight away, you get an update within two working days.
• They aim to resolve things within 10 working days.
• You’ll get confirmation in writing, either by email or letter.

A dedicated complaints team handles investigations. They try to sort issues quickly and look for ways to improve.

Business customers have a few ways to complain. You can use the main customer service email ([email protected]) or write to their Chesterfield office.

Recent reviews suggest they’re not as strong on complaint handling as they used to be. Some long-term customers feel overlooked when they raise concerns.

They don’t publish complaints stats, so it’s tough for newcomers to judge how well they handle issues.
