Portable Oxygen Concentrator UK: Your Guide to Mini Machines

If your consultant has mentioned portable oxygen and your head is already full of questions, you are not alone. Thousands of people across the UK each year are told they need oxygen outside the home, and the first thing they find out is that "portable" can mean many different things. This guide walks through how mini oxygen concentrators are provided in the UK, what you can get through the NHS, and what your options look like if you need to fund a device yourself.

How Oxygen Therapy Works in the UK

Home oxygen in England is contracted out by the NHS to four regional suppliers. Air Liquide covers London and the South West, Baywater Healthcare covers the North West, Yorkshire, the Humber, West Midlands and Wales, BOC covers the North East and the Midlands, and Dolby Vivisol covers the South and East of England. Your local supplier depends purely on where you live.

The NHS provides three main types of portable oxygen. Portable cylinders weigh around 2-3kg and are small enough to fit in a backpack or shopping trolley. Liquid oxygen uses a main tank at home with refillable flasks you top up yourself. And then there are portable oxygen concentrators, which are the devices this guide focuses on.

A mini oxygen concentrator works by drawing in room air, filtering out the nitrogen, and delivering concentrated oxygen through a nasal cannula. Unlike cylinders, it creates oxygen on demand, so there is no refilling, no venting, and no running out halfway through a day out. Most units weigh between 1.5kg and 4.5kg, run on rechargeable batteries, and can be charged in the car or at home.

Can You Get a Portable Concentrator on the NHS?

Here is the part that surprises many people. Yes, a portable oxygen concentrator can be prescribed on the NHS, but it is not routinely offered, and you will not find it advertised. The assessment process is key.

You start with a referral from your GP, consultant, or respiratory nurse. An oxygen assessment team, usually based at your local hospital, will carry out tests. For ambulatory oxygen, this means a walking test where your oxygen saturation is measured while you walk, then checked again while breathing oxygen. If your levels drop and recover slowly, you may be offered a portable supply.

The important detail is that clinical need drives everything. Guidelines state that long-term oxygen therapy is considered when oxygen is needed for more than 15 hours a day. For ambulatory use, a concentrator may be considered more cost-effective than cylinders because it removes the need for repeat deliveries. One patient forum contributor described it as "a little known fact that you CAN BE PRESCRIBED A PORTABLE CONCENTRATOR ON THE NHS," noting the unit cost sits around the £2,500 to £3,000 range, which is why trusts are not always keen to advertise it.

If your walk test shows you benefit, the NHS supplier will arrange delivery, installation, and training. The engineer sets everything up and explains safe use. You also get a backup cylinder in case of a power cut, because a concentrator needs electricity to create oxygen.

The Realistic Picture

Option	Typical Cost	Pros	Cons
NHS prescribed portable concentrator	Covered by the NHS (trusts report unit costs around £2,500-£3,000)	No direct cost to you, clinical oversight, supplier support	Strict eligibility, assessment required, may not always be offered
Private purchase of a mini concentrator	Roughly £1,500-£4,500 depending on brand and flow	Own the device, take it anywhere, no waiting lists	Upfront cost, you manage servicing and batteries
Rental for holidays or short-term use	Weekly or monthly rates from specialist companies	No long-term commitment, good for travel	Adds up over time, availability varies

Buying Your Own Mini Concentrator

If the NHS route is not open to you, or you want more freedom, buying your own portable concentrator is a well-trodden path. Prices in the UK vary widely. A basic pulse-dose machine can be found in the lower range, while premium continuous-flow devices with longer battery life sit at the higher end. Brands like Inogen, VARON, and Philips Respironics all have active UK sellers.

One genuine saving is VAT relief. The UK allows people with a disability to buy certain equipment VAT-free, and oxygen concentrators are explicitly listed. You should be asked to confirm eligibility when you purchase, and reputable suppliers handle this at the point of sale. This can make a real difference to the final price.

Before you buy, check three things. First, does the device match your prescription, meaning the flow setting and pulse versus continuous delivery? Second, what is the battery life, and can you buy spare batteries for long days out? Third, who services it locally, and what does the warranty cover? A machine that sits in a drawer because the battery dies after two hours is no bargain.

The Travel Question

British holidaymakers face a particular challenge. NHS portable cylinders are designed for use near home, and taking oxygen abroad needs careful planning. If you are travelling within the UK, your supplier can sometimes arrange delivery to your destination. For overseas travel, you will need travel insurance and airline approval, and many people find a personally owned portable concentrator is the most practical answer.

The current UK market reflects this demand. Industry observers note the portable oxygen concentrator market in the UK has grown as more people are diagnosed with chronic respiratory conditions such as COPD, asthma, and pulmonary fibrosis. A machine you own can be used in the car, on the train, and on a plane, subject to airline rules, without depending on a delivery schedule.

Practical Steps to Get Started

Ask your respiratory team directly. Phrase the question simply: "Is a portable oxygen concentrator a possibility for me?" Your consultant or oxygen nurse is the gatekeeper for NHS provision.
Push for a proper walking assessment. Ambulatory oxygen is only prescribed after a walk test shows your oxygen levels drop with activity. Make sure you have had this done properly.
Compare NHS cylinders, liquid oxygen, and concentrators. Each has different advantages. Cylinders are light but run out, liquid oxygen refills are easy at home but vent if unused, and concentrators are heavier but never run dry.
If buying privately, get a written quote including VAT relief, delivery, and any setup fees. Ask about warranty length and local repair options.
Contact your electricity provider and register for the Priority Services Register. This free service ensures extra support is available in a power cut, which matters when your oxygen depends on electricity.
Check charity resources. Organisations supporting people with lung conditions occasionally offer grants or advice on funding equipment, and their helplines can point you to local support.

Margaret, a 68-year-old from Sheffield with COPD, spent months using heavy portable cylinders before her respiratory nurse suggested a concentrator review. After her walking test showed a clear benefit, her local trust supplied a portable device that she now uses on her weekly trips into town. She describes the difference as "going from planning every outing around how many cylinders I could carry to just grabbing my machine and going."

The path to portable oxygen in the UK is not always obvious, but it is navigable. Start with your clinical team, understand what your assessment shows, and then weigh the NHS option against private purchase or rental. The right mini oxygen concentrator should let you live your life, not confine it.
