Do I need a survey on a leasehold flat?

‘Do I need a survey on a leasehold flat?’ is a common question from buyers - and while it’s not a legal requirement, it’s almost always a smart move. A survey can flag issues inside the flat and the wider building that could affect value, safety and future costs. You can use the survey results to renegotiate the price or even decide to walk away.

KEY INFORMATION

Do I need a survey on a leasehold flat: At a glance

Yes it’s highly recommended. But it isn’t a legal requirement.

  • A leasehold flat survey can identify potential issues with the flat that could impact its value and your decision to buy it.
  • They can also identify issues in the building’s structure like roof damage or external wall issues, which you’ll typically be jointly liable to cover the cost of fixing.
  • If problems are flagged, you can use the survey to renegotiate the purchase price – potentially saving thousands of pounds.
  • There are several types of flat survey, depending on the level of detail you want and if the property is a new build.
  • A flat survey typically costs £400-£1,000 for a mid-level Homebuyer survey, depending on property value and location.

Do you need a survey on a leasehold flat?

Yes, it’s highly recommended. Some buyers assume a survey isn’t necessary when purchasing a leasehold flat. But skipping the survey when you’re buying a flat can be a costly mistake. If the survey uncovers problems with the property, you can negotiate with the seller or even walk away.

In fact, our research found 30% of buyers who had a survey undertaken before buying their property saved money on their purchase.

One of the main reasons why getting a survey is so important when you buy a leasehold flat is because while the freeholder or management company is usually responsible for maintenance and repairs of the entire building, leaseholders are typically required to contribute to these costs through service charges or a reserve/ sinking fund.

Although exactly what you’ll be required to cover will be set out in your lease.

Jeremy Leaf, founder of North London estate agency Jeremy Leaf & Co and a former RICS Residential Chair explains:

“Flat owners are generally jointly and severally liable for repairs and maintenance in a block, house or other building converted to flats. In other words,  lessees would be individually and collectively responsible for looking after the whole property. Therefore, it’s strongly recommended you instruct the surveyor to inspect as much as possible particularly roof, drains, walls and any basement, if you can.”

Risks of not getting a survey when buying a leasehold flat

  • You could inherit expensive repairs such as a leaky roof, problems with communal areas like failing lifts that you didn’t spot when viewing the flat.
  • A survey can identify other issues that may increase your service charge in the future, for example if the building needs major redecoration.
  • A survey may spot issues like signs of subsidence which can affect the value and safety of the flat even if the issue isn’t directly within the flat itself.

Leasehold flat vs freehold: What’s the difference?

Buying a leasehold flat is different to buying a freehold property.

  • With freehold, you own the property and the land it’s built on.
  • But with leasehold – the typical tenure for flats – you own the property, but only for the length of the lease, and you don’t own the land. Read more in Leasehold vs freehold.

What is a property survey?

A property survey is an inspection of a flat or house’s condition conducted by experts. The experts – surveyors – inspect the property and tell you if there are any issues to do with the condition of the property from minor to significant structural problems.

The level of detail the report will go into will depend on the type of survey you choose. Read on for more on these. The surveyor also provides expert commentary on the property, from the type of walls to the type of glazing.

When you’re buying a leasehold flat, you will usually share responsibility for paying for the maintenance and upkeep of the common areas of the building, via your service charge or a reserve/ sinking fund. So if you’re buying a leasehold flat, you should instruct the surveyor to inspect as much as possible, especially the roof, drains, walls and any basement.

If the survey highlights a problem, such as with the roof, you can ask your solicitor to find out more about plans for repairs and how they will be funded, such as whether this will be from a reserve fund or via the service charge.

Main types of surveys

These are the main types of surveys:

RICS Home Survey – Level 1 (Condition Report)

  • Who it’s best for: Buying a conventional flat or house in reasonable condition

The RICS Home Survey Level 1 is the most basic – and cheapest – survey. It is suitable if you’re buying a conventional flat or house built from common building materials and in reasonable condition. It was previously called a Condition Report.

RICS Home Survey – Level 2 (Home Buyer Report)

  • Who it’s best for: Buying a conventional flat or house in reasonable condition

Previously called a Homebuyer survey, this mid-level survey is a popular choice for most people buying a conventional flat or house in reasonable condition.

You’ll also get recommendations for further investigations where the property surveyor is unable to reach a conclusion with reasonable confidence. The report will also give advice on budget for any repairs and on the amount of ongoing maintenance required in the future. RICS Home Survey Level 2 are offered with or without a valuation.

RICS Home Survey – Level 3 (Building Survey)

  • Who it’s best for: Buying a listed, older property or in poor condition.

This is the most thorough survey offered by RICS and it is usually chosen by people buying a property over 50 years old, of unusual design, a listed building or in poor condition, or if you’re planning to undertake renovations or have any concerns about the property. For more information, read our guide Building Surveys explained.

Getting a survey on a leasehold: an expert’s top tips

Former RICS Residential Chair Jeremy Leaf gives his top tips on getting a survey on a leasehold flat:

1. Set out your expectations clearly

  • When you buy a leasehold flat, it’s not just the flat itself you need to think about. You will generally be jointly liable to pay for the cost of repairs and maintenance of the entire building.
  • Ask the surveyor to inspect as much of the building as possible particularly the roof, drains, walls, communal areas and any basement.

2. Consider service charge spending

  • Jeremy advises: “Converted houses may be 100 years or more old so the service charge may seem low but hide ongoing repairs. Older properties are often built much better than their more modern counterparts but still need regular maintaining and/or updating. If that work has not been carried out on a regular basis then it will become apparent in the service charges sooner or later.”

3. Choose the survey type carefully

  • “Generally, surveys or inspections cover different aspects of a property so the type of report required depends on the time and detail involved which will be reflected in the cost,” he adds. “Therefore, it’s particularly important the report matches your expectations.”

What if I’m buying a new build flat?

  • If you’re buying a new build flat, it’s advisable to get a new build snagging survey. These surveys can identify problems that range from small, cosmetic issues to significant, structural problems.
  • Your new build flat snagging survey will ideally take place before exchange, but if your developer won’t allow this, arrange for your new build snagging survey to be done as soon as you can after moving in.
  • Unfortunately, new build problems are very common. According to the Home Builders Federation National New Homes Customer Satisfaction Survey published in March 2025, 93.7% of new build buyers reported problems to their builder since moving in and over a quarter reported more than 15 snags. Read more in our guide on New build snagging surveys.

A mortgage valuation survey is not a condition survey!

Don’t confuse a mortgage valuation with a survey. A mortgage valuation’s purpose is to reassure the lender that the property is sufficient security for the loan. And the surveyor carrying out the mortgage valuation may not even visit the property as these are often done as desktop valuations.

What type of survey should you get for a flat?

Type of flatMost suitable surveyWhy?

Modern purpose-built flatRICS Level 2A mid-range survey that offers a balance of price vs depth

Do I need a survey on a leasehold flat – Expert view

Paula Higgins, CEO of HomeOwners Alliance, said:

Paula Higgins CEO HomeOwners Alliance

“Yes, we advise that you need a survey when buying a leasehold flat. Hiring an independent surveyor will give you peace of mind as they’ll identify potential issues which you might miss and which could impact your decision on whether to buy or not. You can use the survey report to renegotiate the price. Alternatively, you might ask the seller to fix any problems before you buy. We would particularly recommend it if you have specific worries about any part of the property, you’re unsure about what sort of condition the property is in or you are looking to buy an old or unusual property.”

Frequently Asked Questions

Do I need a survey for a new build leasehold flat?

Yes – if you’re buying a new build flat, it’s recommended to get a new build snagging survey, which identify problems that range from small, cosmetic issues to significant, structural problems.

Can I rely on the mortgage lender’s survey instead?

No – mortgage valuations are for the benefit of lender, not the buyer. Plus, the surveyor may not even visit the property as mortgage valuations are frequently carried out at the desktop. And you won’t see a copy of their report. So it’s a good idea to get your own independent survey.

How long does a flat survey take?

Typically 2–4 hours for the inspection for RICS level 2 surveys and 3–5 working days for the report. But timescales can vary so check with your surveyor.
