What Do Landlords Fear the Most? UK Landlord Risks in 2026

What landlords fear most in the UK is losing money on a tenancy that goes wrong: rent arrears, damage and dirt left at check-out, long empty periods between tenants, and a costly mistake with the law. In 2026 the legal risk has moved up the list. In England the Renters’ Rights Act 2025 abolished section 21 “no fault” evictions on 1 May 2026, new pet rules now apply, and a national landlord register opens in December 2026. This guide sets out the biggest landlord risks, how the rules differ across England, Wales, Scotland and Northern Ireland, and the practical steps that reduce each one.

1. Rent arrears and problem tenancies

A tenant who stops paying is the classic landlord fear, because the mortgage, insurance and bills don’t stop. In England, the route to recovering possession has changed. Since 1 May 2026, landlords can’t use section 21 and must rely on a ground under section 8. According to the government’s guide to the Renters’ Rights Act, the mandatory rent arrears ground now needs at least three months’ arrears (13 weeks if rent is paid weekly or fortnightly), up from two, with four weeks’ notice.

How to reduce the risk:

• Reference thoroughly: income, previous landlord, credit and, in England, right to rent.
• Use a guarantor where income is borderline.
• Consider rent guarantee insurance.
• Act early. A conversation at two weeks’ arrears is far easier than a court case at three months.

2. Eviction: losing the right to regain the property

Many landlords worry about not being able to sell or move back in. In England there are grounds for both, but they can’t be used in the first 12 months of a tenancy, need four months’ notice, and you can’t re-let or market the property to let for 12 months afterwards. Anti-social behaviour and serious breaches have their own grounds. The rest of the UK has its own system:

Nation	How landlords end a tenancy
England	Section 8 grounds only since 1 May 2026; most private tenancies are now assured periodic tenancies with no fixed end date.
Wales	Occupation contracts under the Renting Homes (Wales) Act 2016. A no-fault landlord’s notice gives at least six months and can’t be served in the first six months of the contract.
Scotland	Private residential tenancies are open-ended; landlords must prove one of the statutory eviction grounds at the First-tier Tribunal.
Northern Ireland	Notice to quit of 4, 8 or 12 weeks depending on how long the tenancy has lasted. Longer periods under the Private Tenancies Act (Northern Ireland) 2022 were still at the consultation stage in mid-2026.

How to reduce the risk: choose tenants carefully, keep the relationship professional and take legal advice before serving any notice. A defective notice, or an unprotected deposit, is the most common way to add months to the process.

3. Damage, dirt and deposit disputes

Most tenancies end without a dispute: the Deposit Protection Service says fewer than 5% of the deposits it protects end in one. When they do, cleaning is the most common reason, at 29.38% of its claims in 2025, ahead of damage (18.42%), rent arrears (16.45%) and redecoration (10.88%).

How to reduce the risk:

• Take a detailed, photographed inventory at check-in. Without it, an adjudicator can’t compare the start and end condition.
• Hand over a professionally cleaned property. It sets a clear, provable standard. A pre-tenancy clean had a typical final price of £244 across our jobs.
• Inspect regularly with proper notice, and fix repairs quickly.
• Set expectations before move-out. Sending tenants our cleaning checklist a month ahead prevents many disputes.
• Know the limits. You can’t charge for fair wear and tear or for leaving the property better than it was. In England, the Tenant Fees Act 2019 also stops you requiring tenants to pay for a professional clean as a condition of the tenancy.

Our guide to what damage is the tenant’s responsibility is a useful reference for both sides.

What if a tenant leaves without cleaning?

Compare the property with the check-in inventory, photograph every room with dates, and get a quote or invoice for the clean. You can then propose a deduction for the reasonable cost of bringing it back to the check-in standard, not beyond it. If the tenant disagrees, the deposit scheme’s free dispute service decides on the evidence.

4. What are the deposit rules for UK landlords?

Getting deposit protection wrong is one of the costliest mistakes a landlord can make, and it can also complicate getting the property back.

Nation	Maximum deposit	Protect within	Risk if you don’t
England	5 weeks’ rent (6 weeks if annual rent is £50,000+)	30 days, with prescribed information	Court can order repayment plus up to 3 times the deposit
Wales	No statutory cap	30 days, with prescribed information	1 to 3 times the deposit; a no-fault notice can’t be given
Scotland	2 months’ rent	30 working days	Up to 3 times the deposit, set by the tribunal
Northern Ireland	1 month’s rent	28 days, with information to the tenant within 35 days	Fixed penalty or fine; a continuing offence

In England, the deposit must be returned within 10 days of agreeing the amount, according to gov.uk’s deposit protection guidance. Our guide to getting a full deposit back shows what tenants are told, which helps you anticipate disputes.

5. What are the Renters’ Rights Act pet rules, and what mistakes do landlords make?

Since 1 May 2026, a tenant in England can ask in writing to keep a pet, and the landlord must respond within 28 days (longer only if you need more information or a superior landlord’s consent, and you tell the tenant). You can’t unreasonably refuse. Reasonable grounds include a head lease that bans pets, a property that is unsuitable for the animal, or another occupant’s allergy. The final Act does not let landlords insist on pet insurance, and the five-week deposit cap still applies, so there is no separate “pet deposit”.

Common mistakes:

• Missing the 28-day deadline, or not replying at all.
• A blanket “no pets” answer without looking at the specific animal.
• Refusing because a previous tenant’s pet caused damage.
• Not writing down the reasons for a refusal.
• Treating an assistance dog as a pet.

Tenants can challenge an unreasonable refusal in court. A clear inventory and an end of tenancy clean with carpet cleaning are the practical protection against pet wear.

6. Void periods

An empty property earns nothing but still costs money. Voids are longest when a property needs work between tenants, or when it doesn’t photograph or show well.

How to reduce the risk:

• Plan the changeover: book the check-out, repairs and cleaning for the days after the tenant leaves.
• Take listing photos after the clean, not before.
• Price realistically. In England, rental bidding is banned, so you must advertise a specific rent and can’t accept offers above it.

Across our 9,161 end of tenancy jobs, July and August were the busiest months, so landlords with summer changeovers should book early. London landlords can check local teams on our London end of tenancy cleaning page.

7. Keeping up with regulation

For many landlords, compliance is now the biggest worry. The main dates:

• Landlord database (England): the “Register your rental property” service opens on 15 December 2026 in the West Midlands and rolls out region by region. Each region has three months to register; London’s deadline is 14 October 2027 and the last region’s is 14 November 2027. The fee is £65 a year per property.
• Landlord Ombudsman (England): mandatory membership is expected in 2028, according to the government’s implementation roadmap.
• Decent Homes Standard and Awaab’s Law: both will apply to private rented homes in England, with dates still to be confirmed.
• Energy efficiency: private rented homes in England and Wales must reach EPC band C by 1 October 2030 unless exempt, with a £10,000 cost cap per property.
• Making Tax Digital for Income Tax: quarterly digital reporting since 6 April 2026 for qualifying income over £50,000, falling to £30,000 in April 2027 and £20,000 in April 2028.
• Safety duties: annual gas safety checks, electrical safety inspections at least every five years in England, Wales and Scotland, and smoke and carbon monoxide alarms.
• Registration elsewhere: Rent Smart Wales, your council’s landlord register in Scotland, and the Landlord Registration Scheme in Northern Ireland.

How to reduce the risk: keep a compliance calendar, join a landlord association or use a full-management letting agent, such as Foxtons, Savills or Hamptons, all agents we work with.

8. What are landlords not allowed to do?

Some of the most expensive landlord mistakes are simply things the law now forbids. In England, civil penalties for many breaches reach £7,000, or up to £40,000 for repeated breaches, and rent repayment orders can cover up to 24 months’ rent. Landlords must not:

• Evict without a court order, change the locks or cut off utilities to force a tenant out.
• Enter the property without proper notice (normally at least 24 hours), except in an emergency.
• Take a deposit and fail to protect it.
• Refuse tenants because they have children or receive benefits (England).
• Invite or accept offers above the advertised rent, or ask for more than one month’s rent in advance (England).
• Charge banned fees, such as for referencing, check-out or a compulsory professional clean.
• Raise the rent more than once a year, or outside the section 13 process (England).

9. Market and cost pressures

Mortgage rates, tax changes and maintenance costs squeeze margins. Rents rose 3.8% across the UK in the 12 months to August 2026, to an average of £1,400, according to the ONS, but in England you can raise the rent only once a year. Budget for voids and maintenance, review your mortgage well before a fixed rate ends, and keep the property in good condition so it lets quickly.
