A comprehensive guide to buying a flat

Flats (also referred to as apartments) can be a great choice, especially for solo or first-time buyers looking for city living. They’re often more affordable than houses and, if you want to live in a city centre, generally much easier to come by. However, there are important legal, financial and practical factors you need to understand before making an offer. Our guide will take you through everything you should know when buying a flat in the UK.

In this guide:

Key things to consider when buying a flat

Buying a flat can be complex, so it's critical that every buyer knows what to look for from the start:

  • Lease length - aim for 90+ years

  • Ground rent clauses

  • Service charges - these can range from £1,000 to £5,000 a year

  • Building conditions, including safety checks, cladding, and repairs

  • Mortgage restriction, particularly if it's above a shop or a high-rise

  • Regulations for the apartment building, such as those concerning pets or parking

What's the key difference between buying a flat and buying a house?

There are several important differences between purchasing a flat and buying a house. These can have a big impact on owners and understanding them will help you decide which is right for your lifestyle and budget.

The main difference is that most flats are sold as leaseholds, while most houses are freeholds. When you buy a leasehold, you own the property for a set number of years, but not the land it sits on. A freeholder owns the land, and a management company takes care of the maintenance.

What does owning a leasehold flat mean for you?

  • Additional leasehold costs

    You’ll usually need to pay ground rent and service charges to the freeholder or management company. Management companies may also impose extra admin fees for tasks such as updating records or providing documents to mortgage lenders. These fees can add hundreds of pounds to your moving expenses, and the unpredictability can make budgeting harder.

  • Dealing with third parties

    In addition to the seller and their solicitor, you may also need to deal with the freeholder or a management company, which can make the buying process more complicated and longer.

  • Communal spaces and responsibilities

    As part of your contract with the freeholder, leaseholders are usually required to follow certain rules. These can include, maintaining the inside of your flat, requesting permission for pets or renovations, contributing to building repairs and being considerate of neighbours.

What are the pros and cons of buying a flat?

Like with any purchase, it's important to think about what matters most to you when choosing a property. Here are some important things to consider before buying a flat:

What are the benefits of buying a flat?What are the disadvantages of buying a flat?
Lower purchase prices and deposits make flats attractive for solo buyers or first-time buyer.Flats typically have less living space than a house and no private garden. You also can't extend to add more room as you could with a house.
Flats are often in city centres, close to shops, transport and nightlife.Some mortgage providers are cautious about lending for flats, specifically new-builds, flats above shops or leaseholds with short leases, so it can be harder to get a mortgage for these types of flats.
In most flats, the freeholder or management company takes care of structural repairs and communal areas, saving you time and effort.While flats do appreciate in value, it tends to be at a slower rate compared to houses. Location and transport, will also affect how much your property increases in value.
Flats often have additional security measures with gated access and on-site security. You may also get access to shared amenities like gyms and bike storage.Living with close proximity to neighbours can mean less peace and quiet.
Many flats are now new-builds. This means they're often well-insulated and generally cheaper to heat, resulting in lower energy bills and being better for the environment.Selling a leasehold flat can take longer due to additional legal checks, third-party involvement, and lease terms that buyers' solicitors must review.
Flats may not always come with parking (e.g. garages or allocated car parks), and visitors may need to park in visitor parking spots.
Flat may come with additional restrictions concerning pets, noise level, or running a business from your home.

How long does it take to buy a flat?

There are several factors that can influence how long it takes to buy a flat in the UK, including mortgage approval, third-party checks, property chains, and personal references. From when your offer is accepted, the process of buying an apartment in the UK typically takes around 18 to 22 weeks to complete. But, this can vary depending on how smoothly each stage takes. The entire process from initial talks to completion can sometimes take up to six months in total.

How much does it cost to buy a flat in the UK?

Flats are often cheaper upfront compared to houses, but they can cost more in the long-term. From mortgage fees to stamp duty and ongoing costs involved maintenance and service charges, costs can quickly add up if you're not prepared.

The cost breakdown of buying a flat
Pie chart showing average costs for buying a flat: Conveyancing fees 43%, Mortgage fees 33%, Stamp Duty 10%, Home Buyer Survey 8%, Leasehold fees 8%, Insurance 5%.

  • Mortgage fees: Fees for booking, arrangement, and valuations can total around £2,000 to £3,000. You may be able to add these to your mortgage instead of paying upfront, but doing so will increase the total interest you pay over time.

  • Conveyancing fees: Conveyancing for a purchase usually costs around £1,200 to £1,900. If you’re also selling a property, fees can double.

  • Leasehold fees: Legal fees when buying leasehold flats are typically £250 higher due to extra work. You’ll also pay ground rent (£0–£1,000) and service charges, which vary by property.

  • Stamp Duty Land Tax: First-time buyers start paying stamp duty on properties over £300,000, meaning if the flat is less than this, you will be exempt. If you’re not a first-time buyer, the threshold starts at £125,000 and if it is not your main residence, the rates are higher.

  • Home buyers survey: RICS Home Survey Level 2 are usually recommended for conventional flats in a reasonable condition, costing between £400-£1,000.

  • Insurance: Buildings insurance may be required by your mortgage lender, and contents insurance is your responsibility.

How much money do I need to buy a flat?

Usually, you will need a deposit of at least 5-10% of the property value, alongside money to cover any fees such as conveyancing or stamp duty - this can range from £4,090 to £82,510 on average.

Therefore, how much money you need to buy a flat depends on several factors, such as:

  • The value of the property

  • The location of the property

  • Your deposit size and how much money you need to borrow

  • The level of RICS survey conducted on the property

  • Whether you are a first-time buyer or not

As an example, for a £200,000 flat with a 10% deposit and as a first-time buyer, you can expect to pay:

  • Deposit: £20,000

  • Mortgage fees: £1,400

  • Conveyancing fees: £1,700

  • Stamp Duty Land Tax: £0 (as you would be below the £300,000 threshold)

  • RICS Level 2 Home Survey: £400

  • Ground rent and service charge: £300

Totalling £23,800.

Can you get a mortgage on a flat?

Getting a mortgage on a flat is possible, but it can be more challenging than securing a mortgage for a house. This is because lenders often apply stricter criteria to flats as they're considered a higher lending risk due to leasehold terms, shared ownership, and ongoing costs associated with these property types.

Key factors that lenders check for flat mortgages

Why would a flat not be mortgageable?

Most people can get a flat mortgage with no or minimal issues, but sometimes a flat can be considered un-mortgageable. A lender may refuse a flat due to several reasons, including:

  • A short leasehold

  • Dangerous cladding or a missing EWS1 form

  • Serious structural defects

  • The flat is located above a commercial premise, such as restaurants or bars

  • If the flat is in a high-rise building (5+ storeys)

Financial support to help you buy a flat

Flats are still a very popular and common choice for buyers, and there are many mortgage providers that will lend as long as the property meets their criteria. If you’re unsure, you should speak to a financial adviser who will let you know your options.

As with house purchases, there are government schemes that can help finance your flat purchase, such as Lifetime ISA and shared ownership. Find out more in our guide to first time buyer schemes.

Checklist: Questions to ask when buying a flat

As with any property purchase, there are lots of things to consider before you commit. You may question the practicality of being up one or more floors, whether you need a lift, what communal spaces there are and the refurbishments you’re allowed to make to your home. You’ll also need to find out about things like leases, service charges and ground rent.

Download our checklist of essential questions covering what to ask when buying a flat, so you know exactly what to discuss with the estate agent or seller before putting in an offer.

How long is left on the lease?

  • With a leasehold property, you're effectively buying the right to live in that property for a set amount of time, which can be anything up to 999 years. As time moves on and the lease changes hands, its value reduces. It’s vital you know how long is left on the lease - this should be in the property listing, and your conveyancer will also check it for you.

  • Mortgage lenders often require that properties have at least 80 or 70 years left on their lease. If you buy one with less than 80 years of lease remaining, you may find it challenging to sell in 5 to 10 years' time. Extending a lease can cost several thousand pounds and take many weeks to manage, so if the lease is running out, you should consider negotiating an extension before you buy.

  • You can read more about how to extend a lease in our article.

Are there any restrictions on the property?

  • We’d advise asking the estate agent or seller if there are any specific restrictions that could significantly impact your lifestyle. For example, some flats may prohibit the ownership of pets, subletting, or restrict noise levels, such as not allowing music to be played after a certain time.

  • There can also be restrictions on modifications to the property such as removing carpets, knocking down internal walls or updating the windows and doors. Often, making alterations isn't as straightforward as it seems; you might need to secure written consent from the landlord or freeholder before proceeding with any significant works.

  • These types of restrictions are not always immediately apparent, so if you decide to purchase a flat it is advisable to have your conveyancer double check whether there are any such limitations that would prevent you from enjoying activities or making changes that are important to you.

How much is the ground rent?

  • Ground rent is the regular payment a leaseholder makes to a freeholder for the right to occupy the property. It may be as little as £1 a year, but can be much more, and it’s payable either annually, twice a year or quarterly. It can be fixed or escalating, which makes it one of the most crucial things to look out for when buying a flat. You don’t want to get stuck with ground rent that increases by huge amounts, as this can become very expensive and cause you a headache if you want to sell your home.

Is there a service charge, and what does it cover?

  • Service charges are an essential aspect to consider when moving into a new property, as they can significantly impact your budget. These charges can cover anything from simple maintenance to gardening tasks, concierge services, and swimming pool upkeep. Service charges vary depending on the building and location. For standard flats outside London, they typically range from £1,000 to £3,000 per year. In high-end London developments, charges can reach £10,000 to £15,000, and in rare cases, even £20,000.

  • Knowing the details of these service charges helps ensure there are no surprises after you move in. Ask the property management for a detailed breakdown of the service charges and enquire how often these costs are reviewed and adjusted. This will give you a clear picture of the ongoing expenses and help you budget accordingly.

Is there a sinking or reserve fund for future repairs?

  • It’s worth checking if there’s a sinking fund on the building you’re interested in. This is a reserve fund that’s been collected to cover any planned or unexpected works. The existence and status of such a fund can be especially important in older buildings where significant repairs might be necessary.

Is there a management company?

  • It’s important to understand who you’ll be interacting with regarding your flat, the building and the lease. You’ll be dealing with these people regularly, paying service charges to them and asking them to fix any issues that arise. Therefore, knowing whether you'll be working directly with a professional management company or an individual landlord is essential. This knowledge will help you manage expectations and prepare for the type of communications and transactions you might expect throughout your time in the property.

Is the building compliant with fire safety regulations?

  • Fire safety is essential when buying a flat, especially in larger or high-rise buildings. Ask if the building has passed all required fire safety checks and about any recommendations from recent inspections.

  • If the building has cladding, ask whether it has been reviewed, whether remediation is required, and who is responsible for paying for it. Some buildings qualify for government funding or protections that prevent leaseholders from bearing the cost, while others do not. Your solicitor can confirm whether documents like an EWS1 form have been provided by the seller or freeholder and whether any upcoming safety works could lead to extra costs for leaseholders.

How energy efficient is the flat?

  • A flat’s energy efficiency directly affects your monthly running costs, so it’s worth reviewing the property’s Energy Performance Certificate (EPC) and ask what factors contribute to its rating. Older buildings may have poorer insulation or outdated heating systems, which can increase utility bills.

  • Check the age and condition of key fixtures such as radiators, boilers, and appliances to understand whether upgrades may be needed.

What fixtures are included, and when were they fitted?

  • Fixtures and fittings can significantly influence the overall value and move-in readiness of the flat. Clarify exactly what is included in the sale, and ask when these items were last replaced or upgraded.

  • Knowing the age and condition of fixtures helps you anticipate future costs. If the fixtures are modern and well-maintained, they can save you money in the first few years or ownership. If they’re older, you may need to budget for replacements soon after moving in.

How much is the council tax?

  • Council tax varies depending on the band your property falls into, so it’s important to factor this into your monthly budget. Each property is assigned a band (A-H in England) based on its assessed value, and the amount payable differs by local authority.

  • Typical council tax bands include:

    • Band A – lowest

    • Band B

    • Band C

    • Band D - average

    • Band E

    • Band F

    • Band G

    • Band H – highest

  • Your solicitor or estate agent can confirm the band, or you can check it online using the property’s postcode.

What are transport links and local conveniences like?

  • A flat’s location can shape your daily routine just as much as the property itself. Good transport connections make commuting easier, support long-term resale value and improve access to work, schools and essential services. It’s worth checking how close you are to bus routes, train or tram stations and major roads, as well as the reliability and frequency of those services.

  • Local conveniences like nearby shops, green spaces, healthcare and leisure facilities can also make day-to-day living more practical and enjoyable. Understanding how well-connected the area is helps you judge whether the location suits your lifestyle now and in the future.

What does a conveyancer do when buying a flat?

When buying a flat, a conveyancer (or conveyancing solicitor), handles all the legal work involved, from reviewing contracts and arranging property searches to managing funds and communicating with third parties. Their job is to make sure the purchase is legally sound, your interests are protected, and the transaction runs smoothly.

What a conveyancer does for all properties

  • Review contracts and documents: Checking the draft contract, title deeds, and other paperwork to make sure there are no issues.

  • Order searches and raise enquiries: They’ll order the necessary property searches to identify potential risks such as planning permissions, local authority issues, or restrictions, and raise any enquiries with the sellers’ solicitor.

  • Liaise with your mortgage lender: Making sure all conditions are met so funds can be released on time.

  • Arrange the transfer of funds: Handling deposits, ensuring the seller is paid correctly on completion and paying stamp duty (if required).

Additional checks a conveyancer does for flats

  • Reviews leasehold information: Checking the terms of the lease, how many years remain, and whether clauses could affect your mortgage or resale.

  • Deals with the freeholder or management company: Confirming ground rent, service charges, insurance arrangements, and any restrictions (such as property modifications or pet ownership).

  • Highlights future costs and responsibilities: Ensuring you understand your share of repair costs for communal areas, as well as any rules you must follow.

  • Checks compliance with the Building Safety Act (BSA): For flats that are five storeys or more, your conveyancer will have to check whether the property is affected by the BSA and make sure all necessary safety information and certificates are provided. Find out more about buying a high-rise flat.

By handling these checks, your conveyancer makes sure there are no hidden surprises, giving you confidence that your flat purchase is secure and fully understood before you commit.

Is buying a flat a good investment in the UK?

Buying a flat can be a good investment in the UK, however it depends on factors such as the location, lease terms, your long-terms plans, and the current market demand. Flats in central locations near local amenities and good transport links are often in strong demand with renters and tend to hold their value well, making them attractive for both buy-to-let investors and first-time buyers.

However, leasehold terms, ground rent, and service charges can affect how profitable or appealing a flat is an an investment. Short leases or high charges may reduce resale value or limit your mortgage options.

If you're considering a flat as an investment, it's important to:

  • Look for desirable areas with strong demand.

  • Check the lease length (ideally 100+ years remaining).

  • Understand all ongoing costs.

With the right factors, flats can provide a more affordable entry point onto the property ladder and, in some cases, a solid long-term investment.
