AAngelaWelcome to Cost Saver Conversations. I'm Angela, and I ask the practical questions so you can quickly understand what matters. Today, I'm joined by Asad. Asad: Hi Angela. We are unpacking "Airbnb vs Long-Let in the UK: Avoid These 5 Profitability Pitfalls in 2026" today and tying it back to the wider Cost Saver ecosystem, including tools like Airbnb vs long-let rental profitability tool, so you can turn insights into action quickly. Angela: Just a heads-up before we dive in: we are your synthetic hosts. We are great with numbers, but as AI, we can sometimes be confidently wrong. Think of us as the digital versions of your most knowledgeable, slightly caffeinated friends. Asad: Exactly. Treat this chat as a smart estimate only, not as professional financial guidance. Always check important details with official sources or a qualified expert before making any big decisions. Angela: Welcome back to the Cost Saver podcast! Today we are getting into something that I know has been on a lot of landlords' minds — the whole Airbnb versus long-let thing. And Asad is back to help us make sense of it all. Asad, how are you? Asad: Good, good, thanks Angela. Yeah, this is a — honestly, this is a meaty one. I've been looking forward to it. Angela: So, okay, let's just set the scene. Because I think for years the assumption was, you know, short-term lets just crush it compared to traditional long-lets on profit. Is that still true? Asad: So that's the thing, right? That was the rule of thumb for ages. And it's just... it's not holding up anymore. Not in 2026. New regulations, the loss of some really significant tax perks, operational costs going up — all of that has narrowed the gap, um, dramatically. The easy money is gone. Angela: Hmm. That's kind of a big statement. Asad: It is! But I think people need to hear it. Like, if you bought a property between 2017 and 2022 with dreams of, you know, seven-night bookings and five-star reviews — the landscape has genuinely shifted under your feet. Angela: Right. So you've pulled out five main pitfalls that landlords keep tripping over. Let's go through them. The first one is regulation? Asad: Yeah. Pitfall number one, and it's the biggest single change reshaping the market. For years, anyone with a spare room or a second home could just list on Airbnb with almost no oversight. That era is — well, it's over. The Levelling-up and Regeneration Act 2023 introduced powers that are now being implemented. There's a mandatory national register for short-term lets rolling out across England. Every host needs to be officially logged with the authorities. Angela: Oh! So this isn't just a London thing anymore? Asad: No, no. I mean, London's had its 90-day rule for years — you can't let an entire property short-term for more than 90 nights per calendar year without planning permission, and Airbnb actually enforces that automatically by blocking your calendar. But now local councils everywhere are getting new planning powers. In a lot of urban areas, changing use from a standard dwelling to a short-term let requires planning permission. Angela: And Scotland's even stricter, right? I've heard bits about that. Asad: Yeah, Scotland — all short-term lets need a licence from the local authority. And the fees are, um, they vary wildly. Could be a few hundred quid for a small flat, could be several thousand for larger properties. And here's the kicker — failure to license is a criminal offence. Angela: Wait, a criminal offence? That's — wow, okay. Asad: Yeah. And then Wales — Welsh councils can charge up to 300% council tax on second homes and short-term lets that don't meet strict letting thresholds. People in Gwynedd and Pembrokeshire have seen their bills just triple. Angela: Triple! [exhales] So if you're only making a few grand above costs... Asad: —exactly, an extra £500 licence fee or a massive council tax hike can just wipe that profit out entirely. And the thing people forget is, even if your area doesn't have a scheme today, several English councils — Cornwall, parts of the Lake District, Edinburgh-adjacent authorities — they're actively consulting on controls right now. By the time the rules land, it's too late to restructure. Angela: That's actually quite scary. Okay, so pitfall two — this is the tax one that I think really stings? Asad: Oh, it stings. [laughs] So, the Furnished Holiday Let regime — FHL — for decades, this was the secret sauce. It made short-term letting genuinely lucrative from a tax perspective. From April 2025, it was abolished. And 2026 is the first full tax year where landlords feel the consequences across an entire annual cycle. Angela: So what specifically have people lost? Because I think some landlords still don't fully get what's gone. Asad: Right, so — a lot. Full mortgage interest deductibility against rental income, that's now restricted to a 20% basic-rate tax credit, same as long-lets. Capital allowances on furniture, fixtures and fittings — gone. Business Asset Disposal Relief, which capped Capital Gains Tax at 10% on sale — gone. Pension contributions counted against rental profits — gone. The ability to split income flexibly between spouses regardless of ownership share — gone. Does that make sense? It's like they stripped out every advantage in one go. Angela: Yeah, no, that's — I mean, that's a lot of things to lose at once. Asad: And the numbers are real. For a higher-rate taxpayer with a mortgaged Airbnb property, losing the interest relief alone can mean an extra three to six thousand pounds in tax per year. If you were planning to sell, the loss of Business Asset Disposal Relief could cost tens of thousands in additional CGT. Angela: So in practical terms, a property that used to net, what, eight grand — where does it end up now? Asad: Could be three thousand or less. I mean, I spoke with a landlord — Sarah, in Devon — she runs a two-bed cottage near Salcombe. Her property grossed £32,000 in 2023, netted about £9,500 after costs and tax under the FHL regime. Running the same numbers for 2026, with interest relief restricted and capital allowances gone, her projected net drops to £4,200. Angela: Oh wow. Asad: Yeah. And she's now seriously weighing up a switch to a 12-month let at £1,500 a month, which would net her around £11,000 with a fraction of the work. So the long-let actually comes out ahead. That's the — that's the world we're in now. Angela: That's wild. And it kind of leads perfectly into the next one, because gross income can be so misleading, right? Pitfall three is operational costs? Asad: Spot on. This is where — honestly, this is where amateur landlords get destroyed. You look at a two-bed flat in Bath grossing £35,000 a year on Airbnb, and the same flat long-let to a professional couple fetches £18,000. And you think, well, obvious choice, right? But gross is not net. Angela: Go on. Asad: Okay, so — cleaning fees: £80 per turnover, roughly 80 turnovers a year, that's £6,400. Linen and laundry, £1,500 to £2,500. Consumables — toiletries, coffee, dishwasher tablets — £1,200. Utilities included in the rate, £2,800 to £3,500. Council tax, which is no longer business-rated for most, £1,800 to £2,400. Channel commission — Airbnb, Booking.com — 15% on average, so around £5,250. Property management if you're hands-off, 20% of gross, that's £7,000. Maintenance and wear-and-tear, 8% of gross, about £2,800. Specialist STL insurance, £600 to £900. Accountancy and admin, another £500. Angela: [sighs] That's a lot of line items. Asad: It really is. Add it all up and you're looking at around £29,000 in costs against that £35,000 gross. So you're left with about six grand — before mortgage interest, before tax, and before you've replaced the sofa your last guest spilled red wine on. [chuckles] Angela: [laughs] Right, the red wine sofa. Classic. And the long-let comparison? Asad: Far less dramatic. On £18,000 gross, you've got maybe £2,000 for agent fees, £300 for gas safety and EICR compliance averaged out, £900 maintenance, £250 insurance, about £700 for void periods assuming two weeks, £250 accountancy. Total costs around £4,400, leaving £13,600 net before mortgage and tax. Angela: So the gap between six grand and thirteen-six is... I mean, the long-let actually wins there. Asad: It does in that scenario, yeah. And that's — look, that surprises people because they're so fixated on the gross number. The £35,000 sounds amazing until you actually do the maths. Angela: Okay, pitfall four. This is the occupancy one, and I feel like this is where people really kid themselves? Asad: [laughs] That's a polite way of putting it. Yeah, seasonality is the cruelest reality of short-term letting. New entrants almost always underestimate it. So a typical coastal holiday let — you might see 90% to 95% occupancy in July and August. Great. But then 60%
