Autumn Budget countdown: four in 10 landlords say they'd raise rents if taxes rise - what it means for Clapham and Brixton

The Autumn Budget is almost upon us, and if you're a landlord you can probably feel your shoulders creeping up towards your ears already.

A new survey has put numbers on the mood. And, as usual, the people who'd feel the consequences most aren't the landlords at all. It's the renters.

So what's the survey saying?

LegalforLandlords asked 544 UK private landlords how they feel ahead of the Budget, which is due on 28 October. The cold hard facts:

• 59% are pessimistic about the Budget.
• Just 28% are confident that letting property will still be financially worthwhile in five years' time.
• Capital Gains Tax is the biggest worry for 22%, income tax on rental income for 20%, and the cost of possible energy efficiency upgrades for 18%.
• If the Chancellor raises the tax burden on landlords, 40% say they'd put rents up where they can. 18% would consider selling and 16% would leave the rented sector altogether.

To be fair to the researchers, they point out these are landlords' stated intentions, not a prediction of exactly what will happen. Still, it's a fairly clear message.

And bear in mind this isn't starting from a clean slate. As Property118 has reminded readers, last year's Budget already announced two percentage point increases in tax rates on property income from April 2027.

The Capital Gains Tax argument

Meanwhile the National Residential Landlords Association (NRLA) is lobbying for Capital Gains Tax reform in this Budget. Its argument is simple, and I have to say I agree with it.

At the moment, when you sell, the whole rise in value is treated as profit (apart from certain capital costs). The NRLA's research found that only around one-fifth of the rise in house prices between 2015 and 2024 was a real-terms gain - the rest was inflation. So it wants two changes:

1. Tax the real gain, not inflation, by adjusting the purchase price and qualifying spending for inflation before working out the gain.
2. Give relief for long-term holding, so someone who has housed tenants for years is treated differently from a short-term flipper.

As NRLA chief executive Ben Beadle put it: "It is absurd that investors face Capital Gains Tax on increases in property prices that are simply the result of inflation. That's not a real gain, and it shouldn't be treated as one."

The NRLA also points to Rightmove data showing each available rental property now attracts an average of 10 enquiries, double the pre-pandemic figure. Demand isn't the problem. Supply is.

So what does it mean for Clapham, Brixton and surrounds?

Now ears must perk up, because CGT is a very South London issue.

Picture a landlord who bought a flat off the Northcote Road or a two-bed conversion in Brixton 15 or 20 years ago. On paper, that's a big gain. In real terms, a good chunk of it is simply the pound being worth less. Under the current rules, the taxman doesn't care.

That landlord has three choices: sell and pay up, hold on and hope, or put the rent up to make the numbers work. The survey suggests a fair few will do the last one.

Who wins and who loses locally?

• Renters in Clapham, Brixton and Streatham. If landlords' costs go up again, the survey suggests rents follow. With competition for every decent flat already fierce, renters have very little room to push back.
• Long-standing landlords with big paper gains. CGT reform along the NRLA's lines would help them most. A tax rise would hit them hardest and could push some to sell up - which, of course, means one less rental home on the market.
• Buyers. If more landlords sell, first-time buyers in places like Streatham and Tulse Hill could see a bit more choice. That's the silver lining, but it doesn't help the tenant who has to move out.
• Newer, smaller landlords. Squeezed from both sides - higher tax on rental income from 2027 and rising compliance costs.

My take

Here's the thing. Every time the Treasury goes looking for money in the rented sector, the bill ends up on the tenant's doormat. It's not because landlords are greedy. It's because the sums have to add up, and if they don't, the flat gets sold.

The NRLA's CGT idea is sensible. Taxing inflation as if it were profit isn't fair, and it actively discourages landlords from staying in for the long term - which is exactly the kind of landlord renters want.

Will the Chancellor listen? I'm not holding my breath. My advice in the meantime: don't make a knee-jerk sale based on rumours. Run the numbers on your own portfolio, speak to your accountant, and wait to see what's actually announced. Take independent advice, of course.

So there you have it. A nervous few days for landlords, and potentially an expensive year for renters.

Almost four in 10 London flats sell at a loss: what it means for flat owners and buyers in Clapham, Battersea and Brixton

Here's a headline to put you off your morning coffee. Almost four in 10 London flats that were resold after five to 10 years went for less than the owner paid for them.

Not a typo. Four in 10. And before the doom merchants get going, let's look at what the numbers actually say, and what they mean if you own, or want to buy, a flat South of the River.

So what's happening?

The figures come from e.surv Chartered Surveyors' October house price report, which compared repeat sales using HM Land Registry and Registers of Scotland data over the 12 months to August 2026.

The cold hard facts:

• Across Great Britain, just over a quarter of flats resold after five to 10 years of ownership fetched less than their previous purchase price.
• In London it was almost four in 10 - the highest proportion in the country.
• Among London houses held for the same period, fewer than 4% sold at a loss.
• Around a third of flats in the South East and East of England sold for less than they cost. In the Midlands and the North it was closer to one in five, and in Scotland fewer than one in 10.
• Holding on longer didn't make the problem disappear. Across Great Britain, 16.6% of flats resold after 10 to 15 years fetched less than their previous price, against 1.9% of houses.

e.surv says flats and houses started to pull apart around 2017, as leasehold, building safety, cladding and service charges increasingly shaped the decisions of buyers, sellers and lenders. Interestingly, the gap is much narrower in Scotland, which has a different system for owning and managing flats. The report is careful to say that doesn't prove tenure is the cause, but it suggests the way flats are owned and managed may matter.

And the wider backdrop? The average home in Great Britain was £328,900 in September, down 0.2% on the month and the quarter, but still 1.5% up on a year earlier. London was the only region where prices fell over the year, down 2.3%.

If you want to feel even worse, a Telegraph analysis of Land Registry data put 76% of flats in England and Wales as loss-making in the 12 months to August once you allow for inflation. That's a real-terms figure, mind, not cash.

But what does it mean for Clapham, Battersea and Brixton?

Now ears must perk up, because our patch is flat country. Think of the converted Victorian terraces off Abbeville Road and Lavender Hill, the mansion blocks around Clapham Common, the ex-local authority flats in Stockwell and Brixton, and the newer glass towers along the river at Nine Elms and Battersea.

They are not all the same product, and buyers know it. Bear in mind what the report points to: leasehold terms, building safety and service charges. Those are exactly the things buyers and their lenders now pick apart on every flat purchase.

So, roughly speaking, here's who wins and who loses locally:

• Sellers who bought a flat around 2016-2019. This is the group most likely to feel it. If you bought at or near the last peak and haven't added value since, a nominal loss is a real possibility.
• Owners in blocks with cladding questions or chunky service charges. Expect buyers to ask harder questions and lenders to be choosier. Get your paperwork (lease length, service charge history, any fire safety documents) together before you list, not after an offer.
• First-time buyers. Let's face it, this is good news for you. More choice, more room to negotiate, and sellers who are realistic about price. Do your homework on the lease and the building, though, because the reasons prices are soft are the same things that could bite you when you come to sell.
• Landlords. A flat that hasn't grown in value can still earn its keep if the rent covers the costs. Yield and capital growth are two different questions.

My take

You see, here's the thing. A flat is not a bad investment because it's a flat. It's a bad investment when you overpay, buy a short lease, ignore the service charge or buy into a building with safety issues hanging over it.

The data tells me flat buyers have got wiser, and lenders more careful. Sellers need to catch up. Price it right, have the leasehold pack ready on day one and be honest about the building. The flats that are presented properly still sell. The ones that aren't sit there, and then the price comes down anyway.

Houses, meanwhile, keep doing what houses do in London. If you're a flat owner thinking about the next step up the ladder, the numbers are a reminder to look at the whole move, not just your sale price.

So there you have it. Not quite doom and gloom, but a clear message: in the flat market, the detail is everything.

Do you own a flat in Clapham, Battersea or Brixton and wonder where you stand, or are you a buyer weighing up a flat against a small house? I'd genuinely like to hear how it's playing out on your street. Drop me a line at jeroen@claphampropertyblog.com or call 07837 093554.

The landlord register isn't a one-off: the 28-day rule for landlords in Clapham, Brixton and surrounds

A Facebook post has been doing the rounds. It says the new landlord register is NOT a one-off form but a "live record", where every change - a new gas certificate, a rent rise, even your tenant's partner moving in - must be updated within 28 days or you face a fine of up to £7,000. And, of course, there's a handy checklist "in the comments".

Credit where it's due, the post is mostly right. But "mostly" is doing a lot of work there.

So what's actually happening?

The register comes from the Renters' Rights Act 2025, with the detail in the draft PRS Database Regulations 2026, laid before Parliament on 9 September. Two things the post leaves out:

• The regulations are still a draft. Both Houses have to approve them before they're made.
• The penalties aren't in force. They need a separate commencement order, which hadn't been made when I checked.

Nobody in SW4 is getting fined next week.

The 28-day rule

Under the draft regulations, when any information or document on your landlord or property entry "becomes out of date", you have 28 days to update it. Registering isn't fire and forget.

What's on the record for each property:

• the number of occupants and households
• HMO, additional or selective licence status and numbers
• the gas safety record, EICR and EPC
• the rent, how often it's paid and which bills are included
• whether it's furnished, and whether it's currently let

So yes, a partner moving in changes the occupant count, and the NRLA reads renewed certificates and rent changes as updates too. (The draft regulations don't list trigger events, and official GOV.UK guidance isn't out yet.)

But "every change"? No. Tenant names, deposits and repairs aren't on the list. Fixing the boiler isn't a register event in itself.

It's annual too

Entries must be renewed every 12 months. GOV.UK puts the fee at £65 per property per year, though it can change. And if you have more than one property, they all share the renewal date of your first one.

Quick numbercrunch for a landlord with three flats: 3 x £65 = £195 a year, all due on the same day. Put it in the diary.

What the penalties really are

• Up to £7,000 for failing to register or keep entries up to date. That's a maximum. Each council sets the amount, and there's no minimum.
• Up to £40,000, or prosecution, for knowingly or recklessly giving false information, carrying on more than 28 days after a penalty is final, or another breach within five years of a penalty.
• No rent repayment order just for being unregistered. An RRO only comes into play for the false-information offence, or for carrying on after a penalty.
• No possession order without an active entry. Apart from two anti-social behaviour grounds, a court can't make a possession order while you have no active landlord or property entry. An entry you didn't renew counts as inactive, and so does one where the tenancy and safety details weren't added within 28 days.

A correction from me

In my last post on the register I said the penalty for ignoring it could be two years' rent. That overstated it. Simply not registering means a penalty of up to £7,000 and a block on possession, not a rent repayment order. I also said tenants will be able to check whether their landlord is registered. That's the plan, but not at launch - public access needs further legislation and there's no date yet. I'd rather tell you straight.

But what does it mean for Clapham, Brixton and surrounds?

London is the second-last region. Duties start on 15 July 2027 and the deadline is 14 October 2027, for Lambeth, Wandsworth and Southwark alike. So Streatham, Brixton, Battersea and most of Dulwich all register in the same window. It depends on where the property is, not where you live.

Picture an accidental landlord with one flat off Abbeville Road. She registers in August 2027 and forgets about it. Next spring her tenant's partner moves in and the rent goes up. On the NRLA's reading that's two updates, each with its own 28-day clock. Then, in August 2028, the renewal.

A letting agent can update the tenancy and safety details and whether the property is let. What they can't do is register you in the first place. That's on you.

Who wins? Organised landlords with one folder per property. Who loses? The shoebox brigade.

About that checklist in the comments

I'm not calling any particular post a scam. But "link in the comments" is a classic engagement-bait trick, and those links are sometimes lead-capture forms, paid "compliance packs" or pages dressed up to look like GOV.UK. Register only through the official GOV.UK service (or its official paper form), where the only fee mentioned is £65 per property. Don't pay a third party to "register" you, and be suspicious of any unsolicited "register now" message before the service opens on 15 December 2026.

My take

The post is broadly right, just early and breathless. Good landlords already know when their gas certificate is due. The real risk in Clapham and Battersea isn't a £7,000 fine landing on the doormat. It's a stale entry quietly going inactive just when you need possession.

In summary

So there you have it. A 28-day update duty for the listed items, an annual £65 renewal on one shared date, and penalties not switched on yet. London's window is 15 July to 14 October 2027.

The landlord register opens in December: what landlords in Clapham, Brixton and Streatham need to do now

For the first time ever, England is going to keep a single list of who lets property and where. Scotland, Wales and Northern Ireland have had one for years. Now it's our turn, and it comes with a fee, a deadline and a lot of paperwork.

So what's happening?

The new Private Rented Sector Database, better known as the landlord register, opens in the West Midlands on 15 December 2026. Other English regions follow in stages until August 2027, according to Property Reporter (16 October). Landlords will have three months to register once their region opens, and the fee is £65 a year per property.

To register, you'll need each property's gas safety record, electrical safety report and EPC. Property Reporter's guest piece from Logan Ransley of Landlord Studio (12 October) makes the point that this is where many landlords will discover something missing or out of date. That gas certificate buried in an old email. The electrical report that quietly expired last spring.

And there's teeth. Tenants will be able to check whether their landlord is registered, and once the rules are fully in force a tenant renting from an unregistered landlord can apply to get back up to 24 months' rent. Two years' rent. That should focus a few minds.

Councils are also being funded to enforce the Renters' Rights Act. Ransley's FOI request found Newham's funding more than doubled in a year, from around £169,000 in 2025/26 to more than £364,000 in 2026/27, even though Newham landlords won't have to register until next summer.

It all lands in a busy year. Making Tax Digital started in April for landlords with qualifying income over £50,000, most of the Renters' Rights Act came into force in May, and Property Reporter (12 October) noted only 35% of landlords can name their own MTD start date. TwentyCi found around 560 rental properties a day were sold in Q3 2026, up from around 500 a day a year earlier and fewer than 170 in 2020.

But what does it mean for Clapham, Brixton and surrounds?

Our patch straddles Lambeth, Wandsworth and Southwark, with Streatham and Brixton in Lambeth, Battersea in Wandsworth and Dulwich mostly in Southwark. If Newham's "next summer" is a guide, London landlords probably have a few months yet. Registration for Lambeth, Wandsworth and Southwark landlords is expected in 2027.

Bear in mind that your deadline depends on where the property is, not where you live. If you live in Dulwich but own a flat in Birmingham, you could be registering that one first, from 15 December.

Think about who lets in our area. Accidental landlords who kept a flat in Clapham Old Town when they moved out to start a family. Long-term investors with a few conversions off Streatham Hill. Owners of new-build flats around Battersea Power Station. The professional, fully managed landlord will barely notice. It's the one-flat, do-it-yourself landlord who is most likely to be caught out.

Quick numbercrunch for a landlord with three flats:

• Registration: 3 x £65 = £195 a year
• Risk of not registering: up to 24 months' rent per tenancy

Not a hard choice.

Who wins and who loses?

• Good landlords. Mostly fine. As Dirk Dette of Campions Group put it via Property Reporter, the information requested largely relates to obligations landlords should already be meeting. The difference is that gaps become visible.
• Disorganised landlords. Expired certificates and missing paperwork will show up quickly.
• Rogue landlords. That's the theory, anyway. Veco's chief executive Richard Murray asks the obvious question: will those determined to operate outside the rules simply choose not to register?
• Tenants. A public way to check their landlord is legitimate, and a powerful remedy if not.

My take

I'll be honest, I share Veco's scepticism. The compliant majority will dutifully pay their £65 and upload their certificates, while the cowboys at the bottom of the market carry on as before unless councils have the people and the will to chase them. The Newham funding figures suggest the money is starting to arrive. Whether that becomes enforcement on the ground in Lambeth and Wandsworth is another matter.

That said, I'm not going to pretend this is a disaster. Another layer of admin, yes. Another £65 per property, yes. But for good landlords it's a chance to prove they do things properly, and in a market where tenants have more choice than ever, being visibly compliant could become part of what you're selling.

Practical steps for now, borrowing Ransley's three-step plan: check which region each of your properties sits in; pull all certificates, expiry dates and tenancy agreements into one place per property; and start logging rent, costs and tenant messages as they happen rather than at year end. An hour a month beats a lost week when the council or HMRC comes knocking.

In summary

So there you have it. The register opens on 15 December, costs £65 a year per property, and the penalty for ignoring it could be two years' rent. London's turn looks like 2027, but the paperwork you'll need is paperwork you should already have.

Room rents in inner London just hit £1,002: what it means for sharers in Clapham

Spend ten minutes on the Common on a Saturday and you'll spot them: two or three mates, coffees in hand, walking back from a viewing they've just queued for. Flatshares are the engine room of Clapham. They always have been. And this week the numbers caught up with what I've been seeing on the ground all autumn.

Room rents in inner London have reached an average of £1,002 a month. That's up 2.3% on the quarter and 1.1% on a year ago, and it's within a pound of the all-time record of £1,003 set at the end of 2023 (figures reported this week via SpareRoom). Nationally, the average UK room now costs £769 a month, itself a fresh record, up 1% on the year. So renting a single room in a shared flat down here now costs more than renting a whole one-bed does in large parts of the country.

It isn't a blip either. Surveyors expect more of the same: a net 37% of them told RICS they think rents will keep rising over the next three months. Demand is up, supply is down, and nothing in the pipeline suggests that flips soon.

For a young professional moving to Clapham, Balham or Stockwell, the sum is sobering. A £1,002 room is roughly £12,000 a year before a single bill, before council tax, before the Northern line. Share a three-bed off Abbeville Road or near Clapham Common and the landlord is collecting around £3,000 a month for the flat. That's why so many sharers I speak to are staying put rather than moving in the autumn. The devil you know is cheaper than the devil advertised on the portal.

For landlords, it looks like a win, and in cash terms it is. But I'd read it with a cool head. Rents at or near record highs are not a sign of a healthy market. They're a sign of a market that has run out of homes. Tenant demand keeps climbing while rental stock keeps shrinking, and squeezing more out of a smaller pool is not a strategy, it's a symptom. When affordability stretches this far, you get more arrears, more churn and more tenants who simply can't take the next increase.

Here's my take. If you're a sharer in SW London, the smart move right now is to lock in. A good flat with decent flatmates at a fair rent is worth holding through the winter rather than rolling the dice in a market where every viewing has a queue behind you. Talk to your landlord about a longer term before your renewal lands, because stability cuts both ways and most will take a reliable tenant over a void. And if you're a landlord sitting on a flat that works, resist the temptation to chase the headline number to the last pound. The best tenants are the ones who stay, and in this market keeping a good one is worth more than a £50 bump that pushes them out the door.

Are you sharing in Clapham and feeling the squeeze, or a landlord weighing up a renewal this winter? I'd genuinely like to hear how it's playing out on your street. Drop me a line at jeroen@claphampropertyblog.com or call 07837 093554.
