If you are buying a new build flat or apartment, and in some cases even a new build house, there is a very strong chance the property will be sold on a leasehold basis. Leasehold ownership means you own the right to live in the property for a set number of years (typically 125 to 999 years on a new build) but you do not own the land it sits on. That land is owned by the freeholder, and as a leaseholder you will be required to pay annual charges including ground rent and service charges. These ongoing costs can add £1,500 to £5,000+ per year to the cost of owning your home, and yet they are one of the most commonly misunderstood aspects of buying a new build property. Getting to grips with what you will pay, what it covers, and what your rights are is absolutely essential before you sign on the dotted line.
The leasehold landscape has changed significantly in recent years thanks to government legislation aimed at protecting buyers from unfair practices. The Leasehold Reform (Ground Rent) Act 2022 was a landmark piece of legislation that fundamentally changed the rules around ground rent on new leases. However, many buyers remain confused about what this means in practice, and service charges continue to be a source of frustration for leaseholders across the country. This guide explains everything you need to know about the ongoing costs of leasehold new builds in 2026, including the latest legislative changes, typical charges, what they cover, how to challenge unfair fees, and the growing issue of estate rent charges on freehold new build estates. If you are still working out the full cost of your purchase, our complete cost breakdown guide covers every expense from deposit to moving day.
Ground Rent: What Has Changed
Ground rent is the annual payment a leaseholder makes to the freeholder simply for the right to occupy the property. Historically, ground rent on new build leases ranged from a nominal "peppercorn" amount (effectively zero) to several hundred pounds per year, with some notorious leases including clauses that doubled the ground rent every 10 or 25 years. These escalating ground rent clauses became a national scandal, with some homeowners facing ground rents that would reach tens of thousands of pounds over the life of the lease, making their properties effectively unsellable.
The Leasehold Reform (Ground Rent) Act 2022
The government responded with the Leasehold Reform (Ground Rent) Act 2022, which came into force on 30 June 2022 for most residential leases and 1 April 2023 for retirement properties. The key provisions are:
This is excellent news if you are buying a brand new build flat in 2026. Your ground rent will be zero. However, there are important caveats to be aware of. The Act applies to new long residential leases only. It does not cover commercial leases, community housing, or lease extensions of existing leases (though the government has signalled further reform in this area). If you are buying a new build property that was built before June 2022 but never sold, the ground rent position depends on when the lease was actually granted, not when the building was constructed.
Service Charges: The Bigger Ongoing Cost
While ground rent on new leases has been effectively eliminated, service charges remain a significant and unavoidable ongoing cost for leasehold property owners. Service charges cover the cost of maintaining and managing the communal areas and shared infrastructure of a development. Unlike ground rent, there is no cap on what service charges can be, and they can increase substantially over time.
What Do Service Charges Cover?
Service charges typically fund a wide range of services and maintenance activities. The exact breakdown depends on the type of development, but common items include:
| Service | What It Covers | Typical Annual Cost |
|---|---|---|
| Building insurance | Block buildings insurance policy | £200 - £500 |
| Communal cleaning | Hallways, stairwells, lifts, bin stores | £150 - £400 |
| Grounds maintenance | Landscaping, grass cutting, planting | £100 - £350 |
| Management fees | Managing agent's administration costs | £200 - £600 |
| Sinking/reserve fund | Future major repairs and replacements | £200 - £600 |
| Communal lighting | Electricity for shared areas | £50 - £150 |
| Lift maintenance | Service contracts and repairs | £100 - £400 |
| Fire safety compliance | Alarms, extinguishers, risk assessments | £50 - £200 |
Typical Service Charges by Property Type
Service charges vary significantly depending on the type of development and the level of amenities provided. Here is what to expect in 2026:
The Sinking Fund (Reserve Fund)
The sinking fund, also called the reserve fund, is a particularly important element of your service charge. It is money set aside for future major works such as roof replacement, exterior redecoration, lift replacement, and communal boiler systems. Without a healthy sinking fund, leaseholders can face unexpected demands of thousands of pounds when major works become necessary.
On a new build, the sinking fund starts from zero, so early contributions are critical. A well-managed development will collect between £200 and £600 per unit per year for the reserve fund. This may seem like a lot on a new building, but items like lift servicing, exterior cladding maintenance, and communal area redecoration will be needed within the first 10-15 years. When viewing a new build leasehold property, always ask the developer about the planned sinking fund contribution and check the lease for any provisions relating to major works.
Estate Rent Charges on Freehold New Builds
Even if you are buying a freehold new build house, you may not escape ongoing charges entirely. Many modern housing estates include shared amenities such as communal green spaces, play areas, drainage systems, and private roads that are not adopted by the local council. The cost of maintaining these shared facilities is passed to homeowners through an estate rent charge, also known as an estate management charge.
Estate rent charges are controversial because homeowners often feel they are paying for services that should be provided by the council (which they are already paying council tax towards). The Leasehold and Freehold Reform Act 2024 included provisions to regulate estate management charges and give homeowners more rights to challenge them, but full implementation is still ongoing in 2026. Always ask the developer whether there will be estate management charges on a freehold property, what they are expected to be, who the management company is, and what the escalation provisions are.
How Service Charges Escalate Over Time
One of the biggest concerns for leasehold buyers is how quickly service charges can increase. While the first year's service charge may seem reasonable, costs tend to rise over time as the building ages and maintenance demands increase.
Research by the Leasehold Advisory Service (LEASE) suggests that service charges on residential blocks increase by an average of 5-8% per year, significantly outpacing general inflation. Over a 10-year period, this can result in your service charge more than doubling. On our example of a £2,400 per year starting charge, a 6% annual increase would see costs rise to approximately £4,300 per year after 10 years and over £7,600 per year after 20 years.
Your Rights as a Leaseholder
UK law provides leaseholders with several important rights when it comes to service charges. Understanding these rights is crucial for protecting yourself against unreasonable costs:
How to Challenge Unreasonable Service Charges
If you believe your service charges are unreasonable, there are several steps you can take before resorting to the tribunal:
Step 1: Request a breakdown. Write to the managing agent requesting a detailed breakdown of all service charge expenditure. Compare each line item against the estimate you were given and against what similar developments charge for the same services.
Step 2: Query specific items. If any individual costs seem excessive, write to the managing agent asking them to justify the expenditure. For example, if the insurance premium seems high, ask them to obtain three competitive quotes.
Step 3: Engage with other leaseholders. You are more likely to achieve a positive outcome if multiple leaseholders raise concerns together. Consider forming or joining a recognised residents' association, which gives you additional statutory rights.
Step 4: Apply to the tribunal. If informal approaches fail, you can apply to the First-tier Tribunal (Property Chamber) for a determination on the reasonableness of the service charges. The application fee is modest (currently £100-£300) and you do not need a solicitor, though professional advice is recommended for complex cases.
Permission Fees and Other Hidden Charges
Beyond ground rent and service charges, leasehold properties often come with additional fees that can catch buyers by surprise. Common hidden charges on leasehold new builds include:
| Fee Type | Typical Cost | When It Applies |
|---|---|---|
| Deed of covenant fee | £200 - £400 | When you buy (one-off) |
| Notice of assignment | £100 - £200 | When you sell or buy |
| Consent to alterations | £150 - £500 | If you want to modify your home |
| Consent to sublet | £100 - £300 | If you want to rent out the property |
| Management pack (for sale) | £200 - £600 | When you sell the property |
| Pet permission (if required) | £50 - £200 | One-off or annual |
These fees may seem small individually, but they add up over the life of your ownership, particularly when you come to sell. The management pack fee alone can be surprisingly expensive, with some managing agents charging £400 or more for the information your buyer's solicitor needs. The Leasehold and Freehold Reform Act 2024 aims to cap these fees, but implementation details are still being finalised in 2026.
The Impact on Mortgage Affordability
It is important to understand that service charges and ground rent (on pre-2022 leases) directly affect your mortgage affordability assessment. Lenders include these costs in their affordability calculations, which can reduce the maximum mortgage you are offered.
In this example, a buyer earning £65,000 per year might be offered a maximum mortgage of £340,000 for a freehold property, but only £315,000 for a leasehold property with £2,400 per year in service charges. That is a £25,000 reduction in borrowing capacity. When combined with a smaller deposit, this can significantly limit the properties available to you.

What to Check Before Buying a Leasehold New Build
Armed with this knowledge, here is a comprehensive checklist of what to investigate before purchasing a leasehold new build property:
Leasehold vs Freehold: The Cost Comparison
To put the long-term cost of leasehold ownership in perspective, let us compare the total additional costs over 10 and 25 years:
| Cost Category | Freehold (10yr) | Leasehold (10yr) | Leasehold (25yr) |
|---|---|---|---|
| Service charges | £0 | £30,000 | £110,000 |
| Ground rent (new lease) | N/A | £0 | £0 |
| Estate management charges | £3,000 - £5,000 | Included in SC | Included in SC |
| Permission/admin fees | £0 | £500 - £1,000 | £1,500 - £3,000 |
| Total Ongoing Costs | £3,000 - £5,000 | £30,000 - £31,000 | £110,000 - £113,000 |
This comparison makes it clear that leasehold ownership carries a very significant long-term cost premium. Over 25 years, a leaseholder could pay over £100,000 more in ongoing costs than a freehold owner, even with zero ground rent. This is an important factor to weigh when deciding between a leasehold flat and a freehold house. Of course, the purchase price of a flat may be lower, and there are genuine benefits to having communal maintenance handled for you, but the costs must be factored into your long-term financial planning.
Final Thoughts
Leasehold new builds can be excellent properties offering modern design, energy efficiency, and convenient locations, particularly in urban areas where apartments are the most practical housing option. However, the ongoing costs of ground rent (on older leases), service charges, and administrative fees represent a significant financial commitment that will continue for as long as you own the property. Before committing to a leasehold purchase, make sure you fully understand the current charges, the likely escalation over time, and your rights as a leaseholder.
The legislative landscape is improving for leaseholders, with the 2022 Act eliminating ground rent on new leases and further reforms expected under the Leasehold and Freehold Reform Act 2024. However, service charges remain largely unregulated in terms of the amounts that can be charged, and it is up to individual leaseholders to monitor costs and challenge unreasonable increases.
