New Build Leasehold: Ground Rent and Service Charge Checklist

Most new build flats are leasehold, so you pay ground rent and a service charge on top of the price. Both come straight out of rental income, and the lease terms affect mortgage access and resale. Ask for the figures, the review clause and the lease length in writing before you reserve.

Leasehold in plain terms

With a leasehold flat you own the right to occupy it for a set number of years, while a freeholder owns the land and often the building. You pay for the privilege and for the upkeep of shared areas. The details sit in the lease, a long legal document that rewards careful reading, and in the commonhold and leasehold rules, which have been the subject of reform in England in recent years. Because the legal position has been changing, check the current rules with a solicitor and with official guidance, and do not assume that what applied to an older flat applies to a new lease.

The three numbers that matter

Item	What to find out	Why it matters
Ground rent	Amount, review dates and formula	Escalating terms can hurt resale and lending
Service charge	Budget per sq ft, what it covers, how it is set	Directly reduces rent and may rise
Lease length	Years at completion and any extension terms	Short leases reduce value and lender appetite

Key takeaway: In a leasehold block, the service charge is not a footnote. It is a running cost that scales with how many amenities the developer included, and you pay for them whether or not tenants value them.

Service charge in detail

A service charge pays for cleaning, lighting and repairs of communal areas, buildings insurance, management fees and, in amenity-heavy blocks, concierge, security, lifts and leisure facilities. It also usually contributes to a sinking fund for future major works. Ask:

• Is the figure quoted the first-year budget or a figure based on actual costs?
• What is the cost per square foot, and how does it compare with similar buildings?
• How big is the sinking fund contribution?
• Who is the managing agent and how can leaseholders challenge costs?
• Are there any shared costs with neighbouring buildings or the wider estate?

Early budgets on new blocks can be underestimated, and the first full year of actuals may differ. If the building has been open a while, ask for previous service charge accounts.

Ground rent

Some leases in the past carried ground rents that doubled at regular intervals. That could turn a small payment into a large one over time and made some flats hard to sell or mortgage. Rules have since changed for new leases in England and Wales, but you should still read the clause. If a lease you are offered has a ground rent that is not a nominal amount, ask your solicitor to explain it and what the effect would be on a buyer later.

Lease length

A long lease is reassuring, but remaining term matters over time. As the remaining years fall, value and lender willingness can decline, and extending a lease costs money. For a new lease this is a distant concern, but if you are buying a resale or buying in a building with older terms, check. A broker can tell you which lenders accept a flat with a given length.

Illustrative effect on net income

Using invented figures: a flat lets for £16,200 a year. A service charge of £2,700 and ground rent of £300 reduce this by £3,000, or 18.5% of gross rent. If the service charge rises by 15% in a year, that is a further £405. Over several years, repeated increases can compound. This is why the net yield calculation must use service charge figures, and why a building with a high charge needs a higher rent to match a leaner one. Compare this with the pattern described in buy to let new build flats.

Building safety

After the Grenfell Tower fire, building safety rules in England were tightened, and the Building Safety Act affects the management of higher-risk residential buildings. The government’s overview is on GOV.UK’s Building Safety Act page. For buyers, relevant questions include the building’s height and category, who is responsible for fire safety, and whether any remediation is planned and who pays for it. New buildings should be compliant with current regulations, but ask for the evidence and the warranty details, such as NHBC or another provider.

Checklist for a leasehold new build

1. Request a copy of the draft lease before paying anything beyond a modest reservation fee.
2. Ask for the service charge budget and its breakdown.
3. Confirm the ground rent and any review.
4. Find out who the freeholder and managing agent are.
5. Ask whether the lease permits letting and whether any consent or fees apply.
6. Check the lender’s requirements for the building.
7. Ask your solicitor to flag anything unusual, such as onerous clauses on subletting or alterations.

What to compare

Question	Low-risk answer	Cause for caution
Ground rent	Nominal	Rising, linked to price or doubling
Service charge	Detailed, benchmarked	Vague, unusually low
Lease length	Long, no onerous clauses	Short or with restrictions on letting
Management	Transparent, accountable	Opaque, tied to developer affiliates

Letting restrictions deserve particular attention, because some leases limit subletting or require consent and fees. If you plan to rent the flat, check this before you reserve. A flat that cannot be let freely is not a buy to let.

Estimating charges before you see a budget

A quick way to sanity-check a charge is to feed it into the rental yield calculator as a cost and see how much of the rent it consumes.

If a developer cannot yet give a service charge figure, estimate a range from similar buildings. Ask agents for the charge per square foot in nearby blocks with a similar amenity level, and apply it to your flat’s floor area. A building with a gym, concierge and roof terrace will normally sit at the higher end; a simple block with a lift and a secure entrance will sit lower. Then treat your estimate as a floor, not a ceiling, because first-year budgets are sometimes optimistic.

You can see which amenities a scheme advertises on its listing. For example, the cards on the UK developments page of PropertyDevelopments.com list features such as 24/7 concierge, cinema rooms, co-working space and clubhouses for many projects. Each of those features has a running cost that will appear in the service charge, so use the list as a prompt for questions rather than as a selling point.

Reading the lease as an investor

Ask your solicitor to summarise, in plain language, any clause that affects letting: consent to sublet, notice requirements, restrictions on short lets, who pays for alterations and what happens at lease end. Also ask how the lease deals with major works and how costs are shared. A clear summary before exchange costs little and can save you from owning a flat you cannot let as planned. The yield calculation guide shows where each charge belongs in your numbers. For comparison with other tenures, see new build versus existing property.
