Seasonal Deep Cleaning During Tenancy: Benefits for Both Landlords and Tenants

Cleaning in a rental property doesn’t happen only before moving out. A complete tenancy cleaning cycle spans an entire year and combines regular upkeep with seasonal deep cleans and move-out cleaning. A seasonal deep cleaning is a preventive step focusing on hidden dirt, preventing damage, and keeping the property hygienic. Choosing seasonal deep cleaning during a tenancy benefits landlords—it protects their investment—and tenants enjoy a cleaner space. After all, everyone involved wants the rental experience to be as stress-free as possible!

Understand the complete tenancy cleaning cycle.

The complete tenancy cleaning cycle consists of four key stages:

• Move-in cleaning

It sets the tone for the tenancy, ensures a hygienic, inviting environment, and establishes the expectations for cleanliness for tenants.

• Routine upkeep

Tenants must handle daily and weekly cleaning tasks—vacuuming, wiping surfaces, and cleaning bathrooms to avoid grime build-up and long-term damage.

• Seasonal deep cleaning

Seasonal deep cleaning occurs two to four times yearly and addresses cleaning areas often missed with regular cleans (behind furniture, under appliances, ventilation systems, etc.). It’s a preventive measure to protect the property’s condition and the tenant’s well-being.

• End-of-tenancy cleaning

It’s the final clean before the move-out inspection. Whether professional or DIY cleaning, end-of-tenancy cleaning has to bring the property to the move-in condition and be ready for the new occupant to move in, a full deposit refund can be required.

Seasonal deep cleaning impacts routine maintenance and end-of-tenancy

Seasonal deep cleaning plays an essential role in the complete tenancy cleaning cycle. While regular maintenance tackles everyday hygiene and end-of-tenancy cleaning focuses on making the place move-in-ready, seasonal deep cleans ensure that things don’t go beyond control in between.  

With seasonal cleaning, overlooked areas are addressed, and the gradual buildup of grime and wear is prevented. This reduces the workload at the end of the lease, as well as the risk of deposit deductions and disputes.

Seasonal deep cleaning matters during tenancy—here’s why

Seasonal deep cleaning has many benefits

Many people believe that deep cleaning is only necessary before vacating, but including it throughout the lease has several benefits:

It tackles unseen buildup and long-term wear

A seasonal deep cleaning addresses areas often missed with regular cleaning, such as behind appliances, skirting boards, under furniture, extractor fans, and window tracks. Hidden grime builds up and causes staining, odours, and surface damage—all manageable with seasonal deep cleaning.

It lowers the risk of damage and expensive repairs

Moisture, grease, and dirt deposits can cause permanent damage to fixtures, flooring, and appliances. Seasonal deep cleaning prevents such issues and the need for costly repairs.

It improves health, safety, and hygiene.

Mould, dust mites, and bacteria thrive in dirty homes, especially in a damp climate. A regular deep cleaning improves indoor air quality, reduces allergens, and keeps bathrooms and kitchens sanitary. It supports tenants’ wellbeing and helps landlords comply with housing standards, such as those under the Homes (Fitness for Human Habitation) Act 2018.

It streamlines handovers

Cleaning problems represent the #1 cause of deposit disputes and deductions in the UK. Seasonal deep cleaning will maintain a high level of cleanliness throughout the tenancy, so tenants will have better chances of securing their deposits at the end of the lease. Landlords will experience fewer disputes, faster turnovers, and better collaboration with renters.

How do tenants and landlords benefit from seasonal deep cleaning?

Tenants

Seasonal deep cleaning improves the rental experience as fresher carpets, cleaner bathrooms, and kitchens make the space more comfortable and inviting. Removing dust, mould, and allergens lowers the risk of respiratory irritation by improving air quality. Regular deep cleans also help detect early signs of leaks, damp, or pest infestation.

Landlords

Deep cleaning prevents wear and tear from turning into permanent damage. The property lifespan expands, and long-term maintenance spending reduces as deep cleaning preserves flooring, fixtures, and appliances. Landlords experience better tenant retention as deeply cleaned homes boost satisfaction and decrease turnover. If the properties are spotless at the end of the lease, landlords enjoy fewer void periods and smoother transitions. They will notice less need for emergency repairs and cleaning, and minimal income loss between tenants.

A seasonal approach to deep cleaning: what to do and when

The UK’s changing seasons directly affect how and when properties should be deeply cleaned. Here are our recommendations

Winter (Dec–Feb)

Cold, wet weather leads to condensation, damp, and mould, especially in poorly ventilated areas. During this season, the deep cleaning should prioritise mould prevention, improving air quality, and heating system maintenance. Pipes and windows should be cleaned and sealed to avoid freeze damage.

Spring (Mar–May)

Temperatures and pollen counts increase, so allergen reduction becomes the primary focus. Mattresses and windows require deep cleaning to eliminate dust and enhance indoor air quality. Inspections to detect damage from winter weather should also occur during spring.  

Summer (Jun–Aug)

As the days are longer and temperatures warmer, more insects get inside, and odours linger in neglected spaces. To control pests and maintain the place fresh, deep cleaning should focus on ventilation systems, emptying and sanitising bins, and thoroughly cleaning the kitchen.

Autumn (Sep–Nov)

This is the time to prepare for more indoor living and prevent weather-related problems. Prevent damp and ensure energy efficiency by clearing gutters, inspecting drainage, and deep-cleaning heating appliances.

The financial benefits of seasonal deep cleaning

Cost comparison: seasonal cleaning vs. end-of-tenancy cleaning

Investing in seasonal deep cleaning may seem like an extra expense, but it’s more cost-effective than handling the effects of neglect at the end of the lease. Here’s a UK-based example:

Cleaning Scenario	Estimated Cost (UK)	Outcome
Seasonal Deep Cleaning (x4/year)	£80–£120 per visit (£320–£480 annually)	Maintains high hygiene standards, prevents damage, and makes the end-of-tenancy process easier
One-off End-of-Tenancy Clean (after poor upkeep)	£250–£400+	Intensive work needed, higher risk of deductions or delays
Neglect leading to damage (e.g. mould, carpet replacement)	£500–£1,500+	Repair/replacement costs, possible deposit disputes, and longer void periods

According to the Tenancy Deposit Scheme (TDS), cleaning is the #1 cause of deposit disputes and is discussed in 50-60% of all claims in the UK. If the property isn’t well-kept during the tenancy, disputes occur, and landlords may spend a fortune on professional cleaning and repairs at the end of the lease. Tenants who opt for seasonal deep and regular cleaning have a better chance of receiving the whole deposit. Spending a few hundred pounds on seasonal upkeep can save thousands in repair work, disputes, or lost rent because of property downtime.

Some ROI examples

Cleaning extractor fans

The upkeep cost is around £40–£80 (professional extractor fan and bathroom/kitchen clean), while possible savings range from £300–£1,000. Deep cleaning extractor fans during the tenancy prevents moisture buildup—the leading cause of mould on ceilings and walls. Unaddressed, it can damage plaster, blister paintwork, and cause tenants' complaints and legal problems.

Carpet deep cleaning

The upkeep cost is £80–£120 (annual professional clean), and the potential savings are £600–£1,200. Seasonal deep cleaning will lift dirt and allergens, causing fibre degradation and staining. Clean carpets delay the need for replacement between tenancies—a significant expense for landlords.

All in all, seasonal cleaning tasks are affordable and have high-value results.

How to implement a year-round cleaning strategy

Create a seasonal cleaning schedule

We recommend that tenants and landlords match cleaning priorities with weather-related risks and indoor living patterns.

Spring (March – May)

The focus is to refresh the property after winter and prepare for the summer months. The main tasks should be:

• Deep clean windows, sills, and blinds to remove condensation marks and mould.
• Vacuum and shampoo carpets and upholstery (allergen control).
• Clean extractor fans and air vents (improve ventilation for hay fever season).
• Declutter and clean storage areas (spring reset).
• Examine the place and address any winter-related damage (e.g. leaks, cracks).

Summer (June – August)

During the summer, the priorities are: maintain freshness, control pests, and prepare for possible tenant holidays.

The tasks are:

• Deep clean kitchens and bins to prevent summer pests (flies, ants).
• Clean fridge coils and behind large appliances to prevent overheating.
• Wash curtains and clean inside wardrobes (humidity management).
• Check and clean extractor fans to reduce odours.
• Inspect and clean patio, balconies, or garden furniture.

Autumn (September – November)

This is the season to prepare for increased indoor activity and harsh weather conditions.

The tasks are:

• Clear gutters, downpipes, and drains (prevent blockages and flooding).
• Deep clean radiators, boilers, and heating vents.
• Clean behind furniture and large appliances (damp prevention).
• Wash windows and check seals (improve insulation).
• Assess lofts or crawlspaces for signs of pests or drafts.

Winter (December – February)

During winter, it’s essential to maintain the space hygienically and protect it against moisture and cold damage.

The tasks are:

• Deep clean bathrooms, especially around windows and tiles (mould control).
• Clean ventilation systems and extractor fans to improve air quality.
• Inspect for condensation hotspots and use dehumidifiers, if necessary.
• Examine the areas under sinks and around windows for draughts or leaks.
• Clean and test heating appliances and smoke/CO alarms.

Extra tip!

Set reminder dates at the start of each season or synchronise cleaning with bank holidays to have a consistent, easy-to-handle routine.

Who’s doing what?

Tenants are responsible for regular cleaning tasks, such as:

• Appliance care:
  • Descaling kettles, washing machines, and shower heads.
  • Cleaning oven trays, hobs, and extractor hood filters.

• Bathroom and kitchen upkeep:
  • Regularly wiping down surfaces, tiles, taps, and mirrors.
  • Ventilating and wiping down condensation-prone areas to prevent mould build-up
• Ventilation and air quality:
  • Opening windows regularly to prevent moisture build-up.
  • Dusting vents and removing dirt from the extractor fan.
• Basic seasonal tasks:
  • Cleaning behind and beneath furniture at least once per season.
  • Reporting early signs of issues (e.g. damp patches, leaks, pest sightings).

Landlords/letting agents/managing agents must keep the property safe, habitable, and in good repair. In terms of cleaning, they should handle:

• Annual or bi-annual professional deep cleaning –it’s optional, but expands the property’s durability and improves tenants’ satisfaction.
• Maintaining and servicing appliances (e.g. boilers, extractors, built-in white goods), including cleaning or replacing inaccessible filters.
• Exterior maintenance tasks such as:
  • Clearing gutters and drains.
  • Cleaning and maintaining outdoor areas (paths, patios, communal gardens).
  • Pressure-washing driveways or patios as needed.
• End-of-tenancy cleaning (if mentioned in the lease agreement).

DIY or professional cleaning?

Choose DIY cleaning for routine or moderately intensive seasonal cleaning tasks that don’t require specialist products, tools and methods. Some tasks would be:

• Descaling appliances (kettles, showerheads, washing machines)
• Cleaning extractor fan covers and filters
• Vacuuming and shampooing carpets with rented equipment
• Wiping windows and frames
• Dusting skirting boards, vents, and radiators
• Cleaning behind furniture and white goods

DIY cleaning tips

• Use white vinegar, baking soda, and other natural products to address limescale and odour control
• Rent commercial-grade tools like carpet cleaners
• Avoid damage by following the manufacturer’s instructions when cleaning appliances

Hire professional cleaners when the tasks go beyond general upkeep or require specialist expertise. Here are some examples:

• Full property deep cleans (recommended once or twice per year)
• End-of-tenancy cleaning (especially if required by your tenancy agreement)
• Mould or damp removal (beyond surface cleaning)
• Cleaning high-access areas (e.g. exterior window cleaning above ground level)
• Stain removal from delicate fabrics or upholstery
• Gutter, drain, or pressure-wash services
• You want to fully secure your deposit refund or prepare the property for new tenants.

How to find reliable UK cleaning providers

• Check review platforms like Trustpilot, Checkatrade, or Rated People to understand past work.
• Ask your letting agent or landlord—many agencies recommend cleaning providers as they are reliable and consistent.  
• Confirm insurance and guarantees—dependable cleaners have public liability insurance and offer satisfaction guarantees.
• Look for end-of-tenancy specialists who know which areas to focus on and are familiar with landlords’ standards.

Clarify cleaning responsibilities—here are sample communication templates

Clear communication between landlords and tenants is vital to avoid misunderstanding and deposit disputes. Here are some sample templates for tenancy agreements, seasonal reminders, and welcome packs:

Tenancy agreement clause: cleaning responsibilities

The Tenant agrees to maintain the cleanliness of the Property, including regular cleaning of appliances, surfaces, and ventilation.  Tenants are also responsible for routine upkeep, like descaling appliances and cleaning extractor fans. The Landlord has to ensure structural maintenance and professional deep cleaning once a year. Seasonal deep cleaning is appreciated.

Real-world results of seasonal cleaning

Better deposit refund rate

A tenant in Manchester opted for regular seasonal cleaning, including deep cleaning of carpets, descaling appliances, and cleaning extractor fans. At the end of the lease, the landlord appreciated the property's condition and refunded the tenant the whole deposit. Thanks to the proactive care, the tenants avoided issues like mould and appliance breakdowns—common reasons for deposit deductions.

Extended tenant stays & reduced turnover.

A Sheffield-based landlord noticed tenants collaborating on seasonal cleaning schedules were likelier to extend their lease. By providing tenants with an annual professional deep clean and encouraging them to manage their seasonal tasks, landlords noticed fewer problems caused by wear and tear. The proactive approach reduced turnover and enhanced tenant satisfaction, which led to more extended stays and fewer vacancy periods.

Happier landlord-tenant relations

In London, a tenant and landlord agreed to a seasonal cleaning routine, each handling specific tasks. The tenant was responsible for regular upkeep, while the landlord managed the annual deep clean. Strong communication and collaboration between the parties resulted in fewer disputes and a positive rental experience for both.

What did landlords, letting agents, and tenants say about seasonal deep cleaning?

Margaret, Landlord, Lewisham: “Since following a seasonal cleaning schedule with my tenants, I’ve noticed that my properties have improved. Tenants take better care of them, and I no longer deal with post-tenancy cleaning problems. Tenants leave the properties in great condition, and I am happy to return their deposits. Some tenants even extended their leases, so I have fewer turnovers—no more spending extra on refurbishments!”

Thomas, a letting agent in Manchester, says, “From what I’ve seen, seasonal cleaning has deeply improved the condition of properties I manage. Landlords are happier with the results, and tenants get involved more in maintaining the place during their tenancy. The strategy is simple but highly effective, leading to fewer disputes and seamless transitions between tenancies.”

Olivia, a tenant in Southwark, says: “It was difficult for me to clean during my tenancy, but it all got better after my landlord presented the seasonal cleaning plan. I understood that I wasn’t the only one responsible for deep cleaning at the end of the lease. Plus, the place was always fresh and welcoming. Needless to say, I got my whole deposit back before moving out—isn’t this perfect?”

Closing remarks

Including seasonal deep cleaning into tenancy routines provides an excellent advantage for landlords and tenants. It maintains property value, improves tenants’ rental experience, and fosters a pleasant collaboration between tenants and landlords. Whether you’re a landlord interested in higher tenant retention or a tenant interested in securing the whole deposit, seasonal deep cleaning is one of the best ways to achieve your goal.
