Thetford’s latest release makes the case for 12V compressor fridges in motorhomes and caravans. Read it closely, though, and it’s not a farewell to absorption.

Bigger batteries, factory solar and electric-ready layouts, Thetford says, make compressor refrigeration the right choice for more travellers. Yet its own comparison table still lists absorption as the better fit for off-grid stays.

For UK dealers, the real story isn’t the fridge. It’s the battery behind it.

What Thetford Is Actually Saying

Strip out the marketing and the release makes three points.

  • Compressor fridges suit where vehicles are heading. More battery capacity, solar preparation and electric-ready builds.
  • They help manufacturers. No gas pipework and no external wall grille, which frees up layout and gives a cleaner exterior.
  • They help owners. More shelf space, steady cooling in hot weather, and no need to park perfectly level.

Thetford puts absorption fridges at a 2.5° tilt limit and a 10 to 32°C operating range. Its compressor range, it says, spans climate classes from Subnormal up to Tropical, covering 10 to 43°C.

Dennis van den Berg, Product Manager RV/OEM, says absorption “will remain a logical choice for many travellers in the years ahead.” That’s not a phase-out. It’s a supplier selling both technologies and positioning for whichever way each market moves.

Look Closer: What the Headline Claims Leave Out

Thetford’s case is broadly sound. But four details deserve a second look before anyone repeats it on a forecourt.

The energy moves, it doesn’t vanish. A compressor fridge uses less energy than an absorption fridge running on electricity. That part is fair. But parked off hook-up, absorption runs on gas.

A compressor fridge runs on your leisure battery. The load shifts from the gas bottle to the battery bank.

Cooling speed needs context. Bailey’s owner guidance for its Thetford compressor fridge says the freezer gets cold within about an hour, but the fridge can take several hours to reach operating temperature. Faster than absorption, but still a planning point for the first night.

10 to 43°C isn’t every model. Larger T2000 models such as the T2152 and T2160 are rated SN-T, which covers that span. Some compact van models carry a narrower rating, and night mode can narrow it further. Check the data plate, not the headline.

Consumption figures exist, but rarely reach the buyer. Thetford’s spec sheets list energy use in kWh per 24 hours. The T2160C, for example, is listed at 0.55kWh. At 12V, that’s roughly 46Ah a day.

That last figure is the one that matters.

The Shift Is Real, but Uneven

Look at what manufacturers are fitting and the direction is clear. The 2026 Auto-Trail V-Line 610 Sport has an 84-litre Thetford compressor fridge. The Bailey Adamo pairs a 150-litre compressor fridge with 200W of solar.

Touring caravans are a different story, and for good reason. Swift’s 2026 caravan owner’s handbook describes fridges running on 230V, 12V and gas. For a caravan that spends its life on hook-up or gas, three-way absorption still makes sense.

So far, the examples we found are mostly motorhomes and campervans. That’s also the part of the market holding its ground.

European Caravan Federation figures put 2025 UK new motorhome registrations at around 16,700, up about 1.3%. New caravan sales fell around 19% to roughly 9,250.

Regulation isn’t pushing any of this. Thetford’s T2000 fridges use R600a, a natural refrigerant, and absorption units run on ammonia, water and hydrogen. Neither sits in the firing line of F-gas rules.

RV fridges also sit outside the energy-label scheme for household fridges. There’s no A to G label your customer can compare at a glance. The figure is on the spec sheet, if anyone looks.

What This Means for UK Dealers

If the buyer doesn’t see a consumption figure, you need to show them one.

Thetford’s 0.55kWh works out at roughly 46Ah a day. Owners on UK motorhome forums report similar real-world draws of 40 to 45Ah. Set that against the battery actually fitted and the conversation changes fast.

Here’s what to do this month:

  1. Put an Ah-per-day figure on your spec sheets. Convert the manufacturer’s kWh figure for each fridge you stock. Divide watt-hours by 12 and you have the daily draw your customer will feel.
  2. Check the battery against the marketing. A single small AGM battery and a compressor fridge make a poor off-grid package, whatever the brochure says. One owner of a new 2026 motorhome reports exactly that combination with a 105Ah AGM.
  3. Add three lines to your handover checklist. How long the fridge takes to cool from cold. How night mode works. What happens to the battery in storage if the fridge or isolator is left on.
  4. Brief your workshop on conversions. An absorption fridge’s 12V feed usually only works with the engine running. Swapping to a compressor model means a permanent fused feed from the leisure battery, capping the gas supply and blanking the vents.
  5. Sell the system, not the box. Lithium, solar and a compressor fridge are one package. As with Bailey’s Autograph range, twin batteries and factory solar are becoming the spec buyers look for.

We covered the basics in our earlier breakdown of Thetford’s fridge technology. The advice holds: match the fridge to the customer’s power setup, and say so out loud.

What This Means for Buyers

For a buyer who mostly uses campsites with hook-up, a compressor fridge is close to a straight upgrade. More space, steady cooling in a Spanish August, no fuss about levelling.

For a buyer who wild camps for a week at a time, the answer depends on battery and solar. Get that wrong and the fridge becomes the first thing they complain about. Get it right and it becomes a reason to buy.

The Bigger Signal

Thetford doesn’t need to choose. It makes both technologies, and after its acquisition of Dave Carter & Associates it sells into markets moving at different speeds.

Dealers don’t have that luxury. Every compressor fridge you sell is a promise about the battery behind it.

So here’s the question. Can your sales team tell a customer how many days their fridge will run off-grid? If not, that’s the gap to close before next season’s stock arrives.
