Cylinder gas charges

We explain why BOC add charges for cylinder gases, provide a breakdown of all surcharges and detail additional account-based charges

There are four elements associated with gas purchases from BOC:

  1. Gas price
  2. Environment and energy surcharge
  3. Fixed charge
  4. Cylinder rental

The different price elements cover the different costs associated with supplying cylinder gases.

Why four different price elements?

Each of our customers is unique and wishes to trade with us differently.

Customers may use the same amount of gas each year but some will want to hold higher cylinder stocks than others, some may want to order more frequently than others and some may want their orders delivered while others will prefer to collect.

We believe that charging for each element independently is fair to each customer with only those services used being paid for.

1. Gas price

This is the price for the actual quantity of gas in the cylinder and is based on how much it costs us to produce.

Gases such as acetylene and argon are more expensive to produce than a gas like oxygen and this is reflected in the price.

2. Environment and energy surcharge

The manufacture of industrial gases is highly energy-intensive.

Very large quantities of electricity are required to run air separation plants to produce oxygen, nitrogen and argon.

Carbon dioxide and hydrogen are both produced from natural gas whereas propane is produced by refining crude oil.

The Environment and Energy Surcharge is applied to recover exceptional movements in energy costs. It is increased or decreased in-line with current costs. 

For propane and refrigerants, the surcharge is applied per kilogram of product supplied, for other cylinder gases it is charged per cylinder of gas supplied.

3. Fixed charge

This charge is made for each transaction and covers the costs associated with maintaining our sales outlets and processing your transactions when you do business with us. These costs vary depending on whether you require delivery or if you prefer to collect.

In the case of delivery, the charge includes an element to cover delivery costs.

For collections, the charge includes an element to cover the costs of maintaining our extensive network of BOC trade outlets and Partners. 

Some costs are the same for all transactions as these cover the processing of the order and invoice.

4. Cylinder rental

BOC has a rental charge for all cylinders.

We ensure the quality and safety of our cylinders by performing regular tests, making repairs and replacing cylinders as necessary.

Cylinders and valves are regularly upgraded in line with new technology.

Cylinder rental also gives you the flexibility to swap empty cylinders for full cylinders at any of our locations, take more cylinders as and when you need them and return them when you don't.

BOC has developed options to suit a range of customer requirements and offers monthly, annual, 3-yearly and 5-yearly rentals.

Account-based charges

Our standard conditions of sale include payment by direct debit, email invoicing and payment by set due dates. 

Other charges may apply if a customer wishes to trade with BOC outside of our standard conditions of sale.

Possible charges are:

Non-Direct Debit Fee - £3.00 per invoice

Paper Invoice Fee - £3.95 per invoice

Late Payment Fee - £25.00 per incident

Debt Collection Agency Fee - £15.00 per incident

Replacement charges also apply for any BOC cylinders lost by customers.

Failed Delivery Charge

BOC is committed to providing the highest levels of service to our customers. However, every week we are unable to deliver around 300 orders that customers have placed with us. This is because the customer either declines to accept the delivery when we arrive at their site or is not present to receive it. When this happens, we can’t collect empty cylinders either.

Not only do these failed deliveries bring unnecessary cost to our business, they can also cause delays for other customers and may lead to product shortages.

Accordingly, with effect from 1st January 2017, BOC reserves the right to levy a failed delivery charge equivalent to our standard delivery fixed charge.

Please be assured that we will continue to make every effort to complete deliveries as per the customer order and our service teams will always seek to contact the customer to make the delivery possible. The failed delivery charge will only be raised when through act or omission of the customer, the order is not able to be fulfilled.

Refrigerant Surcharge Monthly Update

Surcharge Details

The surcharge is charged per kg (of product sold) - see the below list of refrigerants which the surcharge is currently applied to.

This page and refrigerant surcharges will be reviewed and updated at the start of each month. The surcharge will be increased or decreased to reflect any changes in price that the manufacturers pass onto BOC.

Additional Information

Please note:

  • The surcharge is only applied to the Refrigerant gas price. There are no changes to cylinder rental or fixed charges.

  • All future price adjustments and the level of the surcharge will be published on this website and will appear on the monthly invoice as a separate 'Environment and Energy Surcharge'.

  • Find out about price adjustments by contacting the Special Products Sales Office on 0800 02 0800 or by talking to the account manager.

  • The surcharges are reviewed at the start of each month.

The impact of the F-gas cap and phase down legislation continues to take affect across Europe, and there will be a significant 30% reduction of CO2 tonnage being placed on the market, which will come into effect in January 2018; this is now significantly affecting the pricing of common refrigerants from the limited number of global refrigerant producers.

To compound the price effects BOC is currently experiencing, the refrigerant producers are now restricting the supply of blended refrigerants (400 series blends and R507A).  The refrigerant press has recently noted, the substantial price rises from the refrigerant producers being experienced by the industry and BOC continues to receive increases on a monthly basis.

The refrigerant producers have, in addition indicated, that they no longer have a long term commitment to produce and sell high Global Warming Potential (GWP) refrigerants and are actively encouraging refrigerant users to move as quickly as possible towards the new generation HFO (Hydrofluoroolefin) refrigerant blends.

From November 1st 2017, BOC introduced a surcharge per kg for all refrigerants, this appears on the invoice as an Energy and Environment Surcharge (EES).  The surcharge is based per kg, therefore this will need to be added to the existing price.

For example, if the cylinder price for R134a at £180.00, divide this by the contents 12kg = £15.00 per kg and if the surcharge for the month is £0.50p then add this to the kg price £15.50, total price for the cylinder £186.00.

Throughout 2017 BOC has received significant price increases from our suppliers across all major product lines, affected by the F-gas legislation.  We continue to work hard to ensure supply continuity and absorb these cost increases where we can. However due to the continuing sheer magnitude of the recent increases incurred, BOC is no longer able to absorb these, and unfortunately we must now pass on a proportion of these costs to our customers.

In the light of the recent significant shifts in the refrigerant producer strategies, how to actively accelerate a transition to a medium low GWP replacement refrigerant should be considered. For any questions on refrigerant selection and evaluation process, please contact BOC on 0800 02 0800 or by email
