Freehold Purchase Calculator | HMRC
Curious about the value of your freehold? Well, look no further. This comprehensive guide to using our freehold calculator tool aims to help you estimate the cost of buying your freehold or extending your lease. Whether you are a freeholder, leaseholder, or part of a freehold collective, understanding the worth of your freehold can be the difference between a savvy financial decision and a costly mistake. The idea of purchasing the freehold of a house or a block of flats can seem daunting. But imagine the increase in your property’s value that could arise after you purchase the freehold. A freehold purchase calculator can help you determine how much this could be.
Our freehold calculator uses professional valuation principles like those of a Chartered Surveyor. It estimates the value of your freehold or the cost of a lease extension. In the context of a flat, the calculator will give you an estimated value of your share of the freehold. This tool can be particularly handy for those in a block of flats looking to purchase the freehold collectively. It allows you to estimate the cost of collective enfranchisement – a technical term for when leaseholders come together to purchase the freehold.
However, do bear in mind that the calculations are approximate. An RICS freehold valuation is required for a more accurate valuation, and It's always a good idea to seek professional or expert advice before deciding.

How to Calculate the Value of Your Freehold
The premium provided by our freehold calculator should be used as a guide only. You shouldn’t use any figures provided by our calculator as evidence in court, nor should you assume the figures are 100% accurate without having your flat or building valued by a chartered surveyor. However, our calculator will give you a reliable approximate range estimate.
You need the following figures to use our freehold calculator:
The current value of the freehold
The annual ground rent
The number of years remaining on the lease
Other variables that are required to determine the cost of collective enfranchisement include the expected increase in your property’s value as well as forecasted inflation and interest rates. Our calculator uses reasonable default values to give you an estimate, but only an RICS Chartered Surveyor can give you an accurate valuation.
Stamp Duty Land Tax When Buying a Freehold
Stamp Duty Land Tax (SDLT) may be payable when you purchase a freehold interest in England or Northern Ireland. The amount due depends on the price paid, the nature of the property, the structure of the transaction and whether any reliefs apply.
How Is SDLT Calculated?
SDLT is generally calculated using the amount paid for the freehold, known as the chargeable consideration. For residential property, the standard SDLT rates are applied progressively, meaning different portions of the purchase price are taxed at different rates.
The standard residential SDLT bands currently begin at £125,000. However, buying the freehold of a block of flats can be treated differently from purchasing an individual house or flat.
Collective Enfranchisement Relief
Where qualifying leaseholders act together to exercise their statutory right to purchase the freehold of their building, collective enfranchisement relief may be available.
Under this relief, the total price paid for the freehold is divided by the number of participating flats to determine the applicable SDLT rate. That rate is then applied to the total purchase price. This can significantly reduce the amount of SDLT payable in some collective freehold purchases.
The relief is not automatic and must be claimed through the relevant SDLT return.
Additional Property Surcharge
Purchasers of additional residential properties will usually pay an additional five percentage points above the standard SDLT rates. However, the higher rates may not apply where the freehold being purchased remains subject to qualifying long leases.
The correct treatment will depend on the existing leases and the structure of the freehold purchase.
Other SDLT Considerations
Different rules may apply where:
the building contains commercial premises;
the purchase is made through a company;
some flats are not participating in the freehold purchase;
the transaction includes linked purchases or other interests;
one or more purchasers are not resident in the UK for SDLT purposes; or
the purchase does not qualify for collective enfranchisement relief.
Scotland and Wales operate separate property transaction taxes and do not use SDLT.
Obtain Professional Advice
SDLT on a freehold purchase can be more complicated than SDLT on an ordinary residential property purchase. Your conveyancing solicitor or tax adviser should confirm the amount payable, whether any relief is available and whether an SDLT return must be submitted.

What is the Ground Rent that a Leaseholder Pays?
Ground rent is a crucial component associated with leasehold properties in the United Kingdom. It represents a mandatory payment a leaseholder must pay to a property's freeholder or landlord.
In a leasehold scenario, the leaseholder acquires the right to inhabit a property for a stipulated period, as laid out in the lease. However, the land on which the property stands remains in the ownership of the freeholder. To compensate for this, the leaseholder must pay ground rent.
The value of ground rent and its payment schedule is outlined within the lease agreement. Ground rent can be a fixed sum or may increase over the lease term, as per the lease conditions.
The ground rent is often a nominal sum, which in traditional leases might be called a "peppercorn". However, certain modern leases may incorporate terms that significantly raise the ground rent over the lease's life. This could cause complications for leaseholders, particularly if they wish to mortgage or sell the property. To address this, the UK government has initiated reforms in leasehold law to ensure a more equitable system for leaseholders.
Freehold Calculator: Cost Factors
In addition to the size and location of your block or building, the price of purchasing your freehold largely depends on how many freeholders are involved, the number of flats in the building, the average length of time remaining on each lease and the potential added value of your building following the purchase. You also need to consider fees such as:
- Marriage Value
The freeholder is legally entitled to 50% of the increase in value of your leasehold. Your flat’s value will inevitably rise after you purchase the freehold and extend the lease.
Compensation
If any of your landlord’s interests are adversely affected due to collective enfranchisements – such as if any of their remaining freeholds lose value – you may have to pay compensation.
By law, leaseholders have a legal right to band together to purchase a share of their freehold, giving the current freeholder the boot. This process is called collective enfranchisement, which can be beneficial for multiple reasons.
By purchasing a share of your freehold, you can increase your flat’s value and assume responsibility for maintenance, which could reduce your service charges by hundreds of pounds every year. Moreover, you can usually extend your lease for up to 999 years free of charge and eliminate ground rent.
Generally speaking, the fewer years you have remaining on your lease, the more it will cost to purchase your freehold. There are also alternatives to collective enfranchisement that might be more affordable. Using this page's freehold purchase calculator, you can gauge the cost-benefit of purchasing your freehold.
Below, we’ll discuss some pros and cons of collective enfranchisement to help you decide the right path for your situation. We’ll also detail some crucial information and fees to familiarise yourself with.
How to Buy the Freehold
If you decide to purchase your freehold through collective enfranchisement, you can either reach an informal agreement with your landlord or follow the legal guidelines. If you choose formal negotiations, you must first serve your freeholder with an official notice containing your offer details. Your landlord/freeholder has a time limit to respond.
Don’t be surprised if your landlord disputes your offer. If they do, you’ll have a time limit to respond to the counteroffer. If you can’t reach an agreement, you can take your case to a Leasehold Valuation Tribunal, but be aware the costs can run into the thousands, and you may be liable to cover some or all of your landlord’s fees.
We highly recommend having your freehold valued by an RICS Chartered Surveyor before making an official offer. Doing so will give you a valuation that can be used as evidence if you need to appeal. First, you can estimate the costs of buying your freehold using our freehold purchase calculator. If you need any advice from a qualified expert, don’t hesitate to call us.
Should I Buy a Share of the Freehold?
Depending on your requirements, there are two alternatives to collective enfranchisement: you can either extend your lease or apply for the ‘right to manage’ your building. You’ll have to club with other leaseholders to take over your building’s management, and the same applies to collective enfranchisement.
If you want to add years to your lease, extending your lease might be a more affordable option than buying your freehold. If you’re considering collective enfranchisement to take over maintenance, you’re likely better off applying for the ‘right to manage,’ which you can often do for free besides the legal fees.
Both lease extensions and collective enfranchisements become more expensive as the number of years remaining on your lease reduces. If you’re approaching the 80-year mark, you should seriously consider taking action sooner rather than later. If you already have less than 80 years remaining on your lease, you can buy the freehold (provided your fellow freeholders are willing to take part) and usually extend your lease for free.
Some studies suggest that those who own a freehold can generally sell their flat for more than those who only have a lease, assuming the two flats are almost identical. According to the estate agency Kinleigh Folkard & Hayward, most surveyors add one per cent to a flat’s value to benefit the freehold.
In short, the benefits of collective enfranchisement include:
You can usually extend your lease by up to 999 years for free. Legal fees may apply
Usually, you won’t need to continue paying ground rent
You can increase the value of your flat while making it more appealing to potential buyers
You can minimise service charges by choosing your providers instead of having to make do with those provided for you
You can take over your building’s maintenance – no more waiting around for slow landlords
