The Deposit Problem Every Tenant Faces

You’ve paid your rent on time, looked after the property, and kept things reasonably tidy. Surely your deposit is safe, right?

Wrong.

Every year, thousands of tenants across the UK lose part or all of their tenancy deposit to deductions they never expected. The average deposit in England and Wales now stands at £1,175 —a significant sum that can make or break your budget for a new home.

The deposit is your money. It should be returned to you in full unless there is a legitimate reason for deductions. Yet data from the Tenancy Deposit Scheme shows that cleaning, damage, and redecoration claims appear in 54%, 49%, and 31% of disputes respectively . Understanding these pitfalls is your first line of defence.

In Portsmouth, where the rental market is competitive and letting agents know exactly what they expect, tenants are particularly vulnerable to deposit deductions . Whether you’re in a military quarter in Southsea, student housing in Cosham, or a flat near Gunwharf Quays, knowing the top reasons tenants lose deposits could save you hundreds of pounds.

This guide reveals the fifteen most common reasons deposits are withheld, explains how to avoid each one, and provides a practical action plan to protect your money.

The Hard Truth: Deposit Loss Statistics

Before we dive into the specific reasons, let’s look at the bigger picture. The numbers paint a clear picture of how common deposit deductions really are.

Nationwide Statistics

According to Tenancy Deposit Scheme data for 2024/25:

*Source: TDS Statistical Briefing 2024/25 *

What This Means for Tenants

While only 1% of tenancies end in formal disputes, many more tenants agree to deductions without escalating to dispute resolution. Research from HomeLet found that 12.5% of renters have had a deposit withheld, with cleaning cited in 39% of cases, redecoration costs in 19%, and damage to fixtures and fittings in the “other” category .

The Deposit Protection Service has similarly found that cleaning is the most common issue causing landlords to make deductions, followed by property damage, redecoration costs, and rent arrears .

The Portsmouth Context

In Portsmouth’s competitive rental market, landlords and letting agents can afford to be selective. Properties need to be presented at their best to attract the next tenant quickly. This means checkout inspections are thorough, and cleaning standards are high—particularly in popular areas like Southsea, where deposits average £750-£2,000 .

The Top 15 Reasons Tenants Lose Deposits

Reason #1: Insufficient Cleaning (The Most Common Reason by Far)

Cleaning is the number one reason tenants lose deposits—and by a significant margin. 54% of all deposit disputes involve cleaning . A separate survey found that 63% of tenants who lost deposit money cited cleaning fees as a reason .

Why It Happens

Many tenants underestimate what “clean” means in the context of a professional checkout inspection. Letting agents compare the property’s condition against the check-in inventory, not against how it looked before you started cleaning.

According to MyDeposits adjudication data, around 30% of all cases deal with an aspect of cleaning . Common failures include:

• Ovens left greasy with baked-on residue

• Bathrooms not properly descaled (particularly critical in Portsmouth’s hard water area)

• Carpets with visible stains beyond normal wear

• Dust and cobwebs in overlooked areas

• Kitchen cupboards not wiped inside and out

The Tenant Fees Act 2019 Limitation

You should know that under the Tenant Fees Act 2019, landlords cannot require you to pay for professional cleaning as a condition of your tenancy . However, they can deduct from your deposit if you fail to return the property to the same standard of cleanliness as when you moved in.

As the official government guidance states: “A landlord or agent cannot require you to pay for a professional clean when you check-out. This includes a professional deep clean… A landlord or agent may request that the property is cleaned to a professional standard” .

How to Avoid It

• Review your check-in inventory carefully—this is the benchmark

• Clean systematically using a checklist

• Hire professional cleaners if you lack time or confidence

• Take dated photos after cleaning as evidence

• Consider professional cleaning with a guarantee if your deposit is at stake

Portsmouth Tip: Southsea’s Victorian properties often have sash windows and original features that require specific cleaning attention. Don’t forget window runner tracks—they’re a common inspection point .

Reason #2: Property Damage Beyond Wear and Tear

Damage features in 49% of deposit disputes, making it the second most common reason tenants lose deposits .

Understanding Fair Wear and Tear

The law distinguishes between fair wear and tear (natural deterioration from normal use) and damage (negligent or excessive harm) .

Examples of fair wear and tear (cannot be deducted):

• Faded curtains

• Slightly worn carpets in high-traffic areas

• Minor scuff marks on walls

• Worn paintwork

Examples of damage (can be deducted):

• Large stains or burns on carpets

• Broken appliances

• Holes in walls from excessive picture hooks

• Scratches on wooden floors from dragging furniture

The Betterment Rule

Landlords cannot claim the full cost of a brand-new replacement for an item that was already old. This is called “betterment” and adjudicators will reduce claims accordingly .

For example: if a carpet has a typical lifespan of ten years and was seven years old when damaged, the tenant’s liability might be limited to around 30% of the replacement cost .

How to Avoid It

• Report any accidental damage to the landlord promptly

• Take photos of existing damage when you move in

• Understand your repair responsibilities

• Keep communication in writing

Reason #3: Redecoration Costs

Redecoration claims appear in 31% of deposit disputes .

Why This Happens

Landlords may claim for:

• Marks on walls beyond light scuffing

• Paint chipped or missing

• Wallpaper torn or damaged

• Unauthorised redecorating or changes to wall colour

The Distinction

Light usage marks are generally considered fair wear and tear—especially after a longer tenancy. However, heavy marks, holes, or unauthorised redecoration can justify a deduction .

How to Avoid It

• Use command strips rather than nails or screws for pictures

• Touch up small marks with matching paint (if you have it)

• Get permission in writing for any redecoration

• Keep curtains closed to prevent sun fading of paint and carpets

Reason #4: Rent Arrears

Rent arrears appear in 10% of deposit disputes . Unlike cleaning or damage disputes, rent arrears are usually black and white—if the landlord has evidence of missed payments, the tenant will find it hard to dispute .

How to Avoid It

• Set up a direct debit or standing order

• Keep a record of all rent payments

• Communicate with your landlord immediately if you anticipate payment difficulties

Reason #5: Unpaid Utility Bills

If council tax, electricity, gas, or water bills remain unpaid at the end of your tenancy, the landlord can deduct these from your deposit .

How to Avoid It

• Take meter readings on the day you move out

• Submit final readings to all utility providers

• Provide forwarding address for final bills

• Cancel council tax and notify the council of your move

Reason #6: Poor Garden Maintenance

14% of deposit disputes involve garden issues . This is particularly relevant in Portsmouth, where many properties have gardens or outdoor spaces.

Common Issues

• Overgrown lawns

• Untended flowerbeds and borders

• Leaves and debris not cleared

• Damaged fences or structures

The Importance of the Tenancy Agreement

Adjudicators will look at whether the tenancy agreement included a clause about garden maintenance . If the property had a well-maintained garden at check-in, you’re expected to return it in comparable condition.

How to Avoid It

• Understand your garden maintenance obligations

• Regular mowing and weeding throughout the tenancy

• Take photos of the garden condition regularly

• If you’re not a gardener, consider paying a professional service occasionally

Reason #7: Missing Items

Your check-in inventory lists all the items provided in the property—furniture, furnishings, and other contents. If any are missing at check-out, the landlord can claim for replacement .

Common Missing Items

• Keys (including spares)

• Remote controls

• Bedding (if supplied as part of furnished tenancy)

• Cutlery and kitchen items

• Curtains or blinds

How to Avoid It

• Keep all original items in the property

• Check the inventory against what’s actually there before moving out

• If something breaks, inform the landlord and ask how to proceed

• Return all keys on move-out day

Reason #8: Broken Fixtures and Fittings

Beyond general damage, specific fixtures and fittings can be costly to replace. This includes light fittings, curtain rails, door handles, and built-in wardrobes .

How to Avoid It

• Report issues promptly—you may be liable if you fail to report a problem that worsens

• Don’t attempt DIY repairs unless you’re confident

• Take care with doors, handles, and moving parts

• Use all appliances according to instructions

Reason #9: Carpet Stains and Damage

Carpets are one of the most inspected items at checkout. While wear from normal use is acceptable, stains require professional cleaning or replacement .

The Distinction

• Fair wear and tear: Furniture indents, slight flattening in high-traffic areas, fraying

• Damage: Wine stains, burn marks, ink spills, pet urine, heavy soiling

Adjudicator Note: “Furniture indents, shading, fraying etc are all fair wear and tear; however stains are ‘damage'”

How to Avoid It

• Treat stains immediately

• Have carpets professionally cleaned before checkout

• Consider professional carpet cleaning with your end-of-tenancy clean

• Keep receipts for any professional cleaning you arrange

Reason #10: Oven and Hob Neglect

Ovens are the single most predictable deposit deduction in Southsea . A greasy oven interior is an almost guaranteed deduction.

Why It’s Such a Common Issue

• Ovens are one of the most difficult kitchen items to clean properly

• Many tenants underestimate the time required

• DIY oven cleaning often misses the interior, racks, and between glass panels

• Letting agents always check ovens thoroughly

How to Avoid It

• Clean the oven regularly during the tenancy

• Use professional oven cleaning products

• Book a professional oven clean as part of your end-of-tenancy service

• Check the oven at the end—turn it on and look through the glass door

Portsmouth-Specific Context: In Southsea’s Victorian properties, older ovens can be particularly challenging to clean. Professional cleaning is strongly recommended .

Reason #11: Limescale and Mould in Bathrooms

Portsmouth’s hard water makes limescale a significant issue . Bathroom mould, particularly in grout and silicone sealant, is another common inspection point.

Why It’s Common in Portsmouth

• Portsmouth water is moderately hard to hard

• Limescale accumulates on taps, showerheads, and tiles

• Older properties may have less ventilation, leading to mould

• Grout discolouration is common and often inspected

How to Avoid It

• Use a descaler regularly during the tenancy

• Ensure proper ventilation to prevent mould

• Clean grout with a specialist product

• Consider professional bathroom cleaning at checkout

Portsmouth Tip: Checkout inspections in Southsea often highlight bathroom limescale and grout mould as key issues .

Reason #12: Failure to Return Keys

Your tenancy agreement likely requires you to return all keys and security devices at checkout. Failure to do so can result in a deduction .

How to Avoid It

• Collect all keys, fobs, and parking permits

• Arrange key return with your letting agent

• Get confirmation in writing

• Consider using a key drop service if available

Portsmouth Tip: Some tenants in shared Southsea student housing have reported being charged for keys that were never provided in the first place. Check your inventory carefully at move-in .

Reason #13: Abandoned Belongings

Leaving furniture, personal items, or rubbish at the property can lead to deductions for removal and disposal .

How to Avoid It

• Arrange to clear all personal belongings

• Donate or sell items you don’t want

• Use council bulky waste collection if needed

• Don’t assume the next tenant will want your furniture

Reason #14: Not Reporting Issues Promptly

If you notice an issue that could worsen—like a leak, damp, or a broken appliance—you have a duty to report it to the landlord .

Why This Matters

• Failing to report a problem that gets worse can make you liable for additional damage

• Landlords can claim for damage caused by your failure to report

• Adjudicators may reduce deductions if the landlord delayed repairs, but the onus is on you to report issues

How to Avoid It

• Report all issues to your landlord or agent in writing (email is best)

• Keep copies of all correspondence

• Follow up if repairs aren’t made promptly

Reason #15: Lack of Proper Documentation

This reason is different—it’s not about what you did or didn’t do, but about what you can prove.

Why This Matters

Deposit disputes are won and lost on evidence. According to the NRLA, “The landlords who consistently win cleaning-related claims are the ones who treat evidence as a non-negotiable part of the process” . This applies equally to tenants.

Key Evidence Tenants Need

• Check-in inventory with photos

• Check-out photos showing the property’s condition

• Cleaning receipts if you used professional services

• Written communication with your landlord or agent

• Repair requests and responses

How to Avoid It

• When you move in, take photos of every room—especially any existing damage

• Keep your check-in inventory safe

• Take photos immediately after cleaning, before checkout

• Keep all emails regarding the property

• Consider asking for a joint inspection before you move out

4. Portsmouth-Specific Deposit Risks

Portsmouth tenants face particular challenges that increase the risk of deposit deductions.

Hard Water Limescale

Portsmouth water is moderately hard to hard, leading to significant limescale buildup. This is one of the most common inspection failures .

Cost Impact:

• Bathroom descaling: £60–£120 if left unaddressed

• Often missed in DIY cleaning

How to Protect Yourself:

• Use a descaler regularly

• Book professional bathroom cleaning at checkout

• Document any existing limescale at check-in

Victorian Property Characteristics

Many Southsea rentals are in Victorian properties with features that need special attention :

• Sash windows: Window runner tracks need to be free of debris

• Original features: Require careful cleaning

• Period tiles: Need specific cleaning methods

• Less ventilation: Can lead to mould issues

Checkpoint Costs:

• Window runner tracks: £30–£60 if neglected

• Grout mould: £60–£120 deduction

Student Housing Pressures

Portsmouth’s student rental market means many tenants are moving during exam periods. Time pressure and shared responsibility can lead to cleaning failures .

Student Deposit Data:

• Over a fifth of student renters lose part of their deposit

• Cleaning is the most common issue

• Shared properties increase the risk of disputes

Protection Strategies:

• Agree a cleaning rota

• Split the cost of professional cleaning

• Book early to avoid peak season premiums

• Keep all housemates informed

Military and MOD Accommodation

Service families face particularly high standards for march-out inspections . MOD inspections require returning properties to a standard that many tenants find challenging.

5. How to Protect Your Deposit: A Ten-Point Action Plan

1. Document Everything at Move-In

• Take photos and videos of every room

• Note any existing damage or cleanliness issues

• Send your notes to the landlord or agent in writing

• Keep your check-in inventory safe

2. Understand Your Tenancy Agreement

• Know what’s expected of you at checkout

• Check for specific cleaning or garden requirements

• Understand the deposit use clause

3. Maintain the Property During the Tenancy

• Clean regularly—it’s easier than a big clean at the end

• Report issues promptly

• Keep up with garden maintenance if required

4. Don’t Assume “Good Enough” Is Enough

• Checkout inspections compare to your check-in inventory

• “Much better than before” isn’t the standard

• Your landlord doesn’t care how hard you tried—only about results

5. Consider Professional Cleaning

• Professional cleaning costs £160–£300 for a typical Portsmouth property

• Cleaning deductions average £150–£300

• Professional cleaning offers a guarantee and peace of mind

• A professional receipt strengthens your dispute case

6. Do a Pre-Checkout Inspection

• Inspect the property 3-4 days before checkout

• Use a checklist and compare to the check-in inventory

• Fix issues while you still have time

7. Take Photos After Cleaning

• Document the property’s condition after cleaning

• Take photos with timestamps enabled

• Include wide shots and close-ups

8. Keep All Receipts

• Professional cleaning receipts

• Carpet cleaning receipts

• Repair receipts

• Any other related evidence

9. Communicate in Writing

• Email your landlord or agent

• Keep copies of all correspondence

• Be polite but clear about your position

10. Challenge Unfair Deductions

• Don’t accept deductions you disagree with

• Request evidence for all claims

• Use the deposit protection scheme’s dispute resolution service

6. When to Challenge Unfair Deductions

You have the right to challenge any deduction you believe is unfair. The deposit protection scheme’s Alternative Dispute Resolution (ADR) service is free, impartial, and binding .

Common Reasons to Challenge

• No check-in inventory: The landlord can’t prove the starting condition

• Betterment: Being charged for new items when old items need replacement

• Unreasonable costs: Being charged £350 for a deep clean when only the oven needed attention

• Fair wear and tear: Being charged for normal deterioration

• Professional cleaning requirements: Being forced to pay for a professional clean (prohibited under Tenant Fees Act 2019)

The Evidence Required

To succeed in a dispute, you need:

• Clear evidence of the property’s condition at check-in (inventory and photos)

• Clear evidence of the property’s condition at check-out

• Evidence of your cleaning efforts (receipts, photos)

• Communication with the landlord or agent

The Adjudication Process

1. Negotiation: Try to resolve the dispute directly

2. Formal dispute: Raise the dispute through the deposit protection scheme

3. Evidence submission: Both parties submit their evidence

4. Adjudication: An impartial adjudicator reviews the evidence

5. Decision: A binding decision is issued

Statutory Guidance: “You should ask your landlord or agent to justify their costs by providing suitable evidence (such as an independently produced inventory, receipts and invoices)

7. Conclusion: Your Deposit is Your Money—Protect It

Your deposit is your money, not a slush fund for routine maintenance or improvements. The law protects you from unfair deductions, but the system works best when both parties are prepared.
