Ongoing landlord costs

Being a landlord involves a range of recurring expenses that extend far beyond the initial investment. Here’s a breakdown of the key ongoing costs you should anticipate:

Mortgage payments

  • Buy-to-let mortgages often come with higher interest rates compared to residential mortgages. It’s vital to account for these rates when calculating monthly expenses to ensure profitability.
  • Some buy-to-let mortgage lenders may have conditions of mortgage, for example, the need to appoint an agent that is Propertymark registered and can provide a professionally drafted Tenancy Agreement

Property maintenance and repairs

  • Regular upkeep, such as painting, plumbing, and minor electrical work, is essential to maintain the property’s standards and appeal. Allocating a maintenance budget helps ensure the property remains tenant-ready.
  • Issues like boiler failures or structural damages can arise unexpectedly. Establishing a contingency fund will help cover such unforeseen expenses and prevent disruptions.

Safety certifications

  • Gas safety certificate: This certification is legally required annually to verify the safety of all gas appliances, such as boilers, cookers, and heaters. It typically costs around £115 but may vary depending on your location and the complexity of the inspection. Non-compliance can lead to severe penalties, making this a critical expense.
  • Electrical Safety Certificate: Required at least once every five years, this ensures that the electrical systems in your property meet safety standards. The cost of obtaining an electrical safety certificate depends on the size and condition of the property, with prices typically around £300. Allocating this expense in your long-term budget helps avoid potential hazards and legal issues.
  • Smoke and carbon monoxide alarms: All rental properties must have functional smoke alarms on every storey and carbon monoxide alarms in rooms with solid fuel-burning appliances. While the initial installation cost varies based on the property size and type of alarms, maintaining regular testing and replacing batteries ensures ongoing compliance and tenant safety.

Insurance

  • Landlord building insurance: This policy provides protection against structural damage caused by events such as fires, floods, or storms. The cost of premiums depends on factors like the property’s location, age, and size. For example, properties in flood-prone areas may incur higher premiums. Adequate coverage ensures that repair or rebuilding costs are covered, preventing significant financial losses and giving landlords peace of mind.
  • Contents insurance: For furnished properties, contents insurance is crucial for covering damage to items like furniture, appliances, and other fittings. Premiums are calculated based on the value of the contents, making it important to accurately assess the replacement cost of all items included in the rental. While this type of insurance is optional for unfurnished properties, it remains a valuable safeguard for landlords offering fully or partially furnished property.

Letting agent fees

  • Tenant acquisition: Finding reliable tenants is one of the most critical aspects of letting your property. Letting agents charge a fee for marketing the property, conducting viewings, and performing tenant referencing checks. Fees can vary widely, with online agents often being more affordable than high-street agents but what is included and how hands-on you need to be will vary as you might expect. Online services often charge a flat fee, while high street agents typically charge a percentage of the first month’s rent. Comparing what is included can help landlords because depending on your availability and prevailing market conditions, what is required and valuable will vary. At Hamptons, we offer expert tenant acquisition services, ensuring your property is marketed effectively and attracts high-quality tenants.
  • Management fees: For landlords who have limited time and availability, or who don’t live locally to their rental property, property management services can be invaluable. Learn more about the benefits of property management and how it can simplify your landlord responsibilities. This will include finding the tenant, rent collection, maintenance coordination, and tenant communications. Fees typically range from 12% to 17% plus VAT of the rental income. For instance, on a property renting for £1250 per month, management fees at 15% plus VAT would be £2,700 annually. For many landlords, the value of the equity in their property and their availability to ensure their obligations are met means that the additional costs are a worthwhile investment.

Other costs & charges relating to your tenant moving in

  • Tenancy Agreements: If you are letting with a high-street agent, and certainly if you have appointed them to manage your property, they will almost certainly offer to provide the Tenancy Agreement documents which are critical in protecting your rights including the right to gain vacant possession. Sometimes the tenancy agreement will form part of a package, with other agents’ costs including references and Deposit Registration. In most instances, the tenancy will be impacted by the Tenant Act 2019 and no costs will be payable by the tenant. It is critical to avoid fines and to ensure you can get vacant possession of your property that your tenants deposit is registered with one of the three government-authorised schemes offering free arbitration in the event of a dispute at the end of Tenancy. Depending on inclusions, the cost will vary from £150-450 with most agencies.
  • Cleaning: To ensure a smooth move-in, it is important that the property is professionally cleaned prior to the start of the tenancy. Cleaning will include steam cleaning carpets, deep cleaning of kitchen appliances, limescale removal and cleaning windows. Most agents will be able to introduce a third-party supplier to undertake this and at the end of tenancy, your tenant will be obliged to ensure the property is cleaned to the same standard. Costs will vary depending on the size and contents of the property.
  • Inventories: The first time you let your property you will need to have an inventory ‘made’ and a check-in conducted. The make can be re-used on subsequent lets (although we recommend updating for every tenancy). For each new tenant that moves in, you’ll need a new check-in and at the end of tenancy, a check-out. The inventory should be provided by an independent third party to ensure it isn’t biased, and whilst the tenant can attend, it's recommended the landlord attends after the check-in to show the tenants the workings of the property. The inventory is essentially the itemisation of all contents including fixtures and fittings (if you are letting unfurnished). The check-in and check-out detail the cleanliness and any wear and tear on the contents together with the meter readings. As with the cleaning, your agent will be able to help introduce you to a supplier who can help and the cost will vary depending on size and content.

Void periods

  • Voids are a useful period to prepare for you new tenants, however unoccupied periods can significantly affect your cash flow, as rental income temporarily halts while expenses such as mortgage payments, maintenance, and insurance continue. Planning ahead by budgeting for potential vacancies—typically by setting aside a portion of your rental income—can help mitigate financial strain, maintain stability, and ensure you’re prepared to cover essential costs during these periods.

By understanding and preparing for these ongoing costs, you can manage your property investment effectively and build long-term financial success.

Regulatory and compliance costs

Regulatory and compliance costs are a crucial aspect of property management, ensuring your rental property meets legal standards and remains a safe and attractive option for tenants. Here’s what landlords need to consider:

Energy Performance Certificate (EPC)

  • An EPC is a legal requirement for landlords to evaluate the property’s energy efficiency. It costs around £115 and remains valid for 10 years, making it a key component of your compliance plan.
    Learn more about the process in our guide on how to get an EPC.

Licensing

  • For landlords renting to multiple tenants who form separate households, a HMO Licence is mandatory. Stay updated on new property licensing schemes that may affect your obligations as a landlord. Fees vary depending on the local authority. For example, in Brighton, costs can range between £690 and £906. Ensure you check your local council’s requirements to remain compliant. Stay updated on new property licensing schemes that may affect your obligations as a landlord, especially in light of potential changes following the Renters' Rights Bill.

Taxation

Income tax

  • Income generated from your rental property is taxed as part of your personal income. The amount you owe depends on your total earnings, with rates aligned to UK tax bands. Keeping accurate records and declaring your rental income is essential to avoid penalties and ensure compliance with HMRC.

By staying informed about regulatory and compliance costs, landlords can ensure they operate within the law while maintaining a professional and trustworthy reputation.
