The following article is published in The Moment Magazine - October 2026
The Moment met with Lisa Thornton, Partner and Head of Commercial Property at Hegarty, to understand the commercial lease clauses that can affect your business the most.
Peterborough is changing. According to the 2026 Cities Outlook report, Peterborough is the fifth fastest-growing city in the UK. It has also been ranked sixth in a league table of the best places to start a business. All good news for its small and medium-sized enterprises, which are innovating, developing, and growing on a daily basis.
When it comes to setting up or running a business, deciding to take on commercial premises is one of the biggest financial commitments you will ever make. Whether you’re looking at a shop, café, office, workshop or warehouse facility, gaining professional expertise to guide you through the process is incredibly important.
A commercial lease is the agreement that allows a company to occupy property for business purposes. It determines how the premises can be used, who pays for repairs, how much the rent can increase, whether the business can leave early and much more. The terms of the agreement can be lengthy, complex, and often have long-term legal and financial implications.
That’s where commercial property solicitors can help: working with businesses to manage the risks associated with leasing premises. Specialist legal advice helps to ensure the process runs smoothly while protecting your long-term interests.
Hegarty can advise businesses of all sizes and sectors on commercial leases. Deeply rooted in the wider Peterborough area (with offices in the city itself as well as the surrounding towns of Stamford, Oakham, Market Deeping and Bourne), the organisation combines strong local market knowledge with technical legal expertise.
“We completely understand the opportunities and challenges facing businesses across the region,” says Lisa Thornton, Partner and Head of Commercial Property. “Hegarty is well-known locally and has built an incredibly strong reputation over the years. We believe it helps to know what’s going on in the local area. Peterborough city centre has changed in the past 20 years, so our local knowledge means that clients can trust us to help them and to understand their situation - providing clear, focused advice and practical solutions.”
Deciding to grow, develop, or move your business is a big step. There are several things you should keep in mind before entering into a commercial lease, because sometimes even subtle differences in the wording of the terms can make a big difference to your obligations and liabilities. It’s vital to know what you’re signing up for, so that your business doesn’t experience any unexpected consequences further down the road.
Lisa explains: “It's incredibly important to understand a lease before entering into it, because it creates a legal and financial framework. It sets out who's responsible for what, how long the lease term is going to run for, what the rent is, if there's any service charge payable, who actually insures the property, which risks are insured, and even the extent of the premises.”
She continues: “It's our job, as commercial property solicitors, to make the terms easier to interpret. Understandably, business owners are focused on their business. And commercial property leases can be quite complicated and contain lots of confusing terminology. We know what to look for and can point out to you when something's unreasonable.”
“From the start, we look at your business and its objectives and check that the lease is suitable for what you actually want to achieve. We look at the title and check that the landlord has the right to grant the lease in the first place and review any restrictions. There are all sorts of things that need to be checked to ensure that the rights and responsibilities of the lease are appropriate for your business.”

So, what are the common commercial lease clauses that can affect your business the most? A seemingly minor provision can become extremely important when circumstances change. Getting the lease right in the first place can protect the long-term future of your finances and the business itself. Rather than simply negotiating the lowest starting price for rent, it’s important to focus on the overall risk profile of the agreement.
The initial draft lease will usually be issued by the landlord’s solicitor and may be heavily weighted in their favour. It is therefore imperative to negotiate lease terms to better suit your business and to be fully aware of your commitments before signing.
As a business owner, the rent amount is usually the first thing you look at. But it’s important to consider the way it can change over the lifetime of the lease. The terms may contain a rent review clause, which allows the landlord to increase the rent at certain intervals: perhaps linked to open-market rental value, inflation, fixed increases, or turnover. A landlord will generally want this to be on an ‘upwards only’ basis, not always taking into account market conditions. For a small business, an affordable rent at the start of a lease can become more expensive over time.
Another element to think about is service charges, which can be an additional cost, particularly where a business occupies part of a shopping centre, office building, or other multi-let property. A service charge may cover items like communal cleaning, security, lighting, and management for shared areas. It's important to establish whether major works, improvements, or management costs can be passed on too.
Next, what are your repair and maintenance obligations? Some leases ask for responsibility only for the internal parts of a property, while others can place much broader obligations. Leases are often drafted on a ‘full repairing’ basis, meaning (irrespective of the condition when the tenant first took occupation) there will be the requirement to return the property in a good state of repair at the end of term. This means tenants can find themselves responsible for costly repairs far beyond what they expected.
Many businesses need to adapt premises to suit their operations. For example, a restaurant may need specialist equipment, an office may benefit from extra meeting spaces, while a shop requires signage. It’s important to establish what changes are permitted, which require landlord consent, and whether alterations must be removed at the end of the lease. Thinking early on about what you might need and getting agreement from the landlord before entering the lease will save you from potential issues and operational delays later on. A permitted use clause determines what you’re allowed to do at the premises, and this can have a major commercial impact. How you intend to run your business may evolve, so make sure future business development is considered too.
A landlord may ask the owner or director of a small business, particularly when newly established with limited assets or trading history, to provide a personal guarantee. This can potentially make an individual responsible for obligations that the company itself fails to meet. Any guarantor needs to be properly advised on the liabilities that they, personally, will be taking on.
What happens when you reach the end of your commercial lease? It might seem odd to consider leaving a lease when you’re just entering one, but it’s important to sort out how it will end and what it will entail. Firstly, do you have security of tenure? This valuable addition means you may have a legal right to remain in the premises and seek a new lease when the existing one expires, rather than automatically having to leave.
Perhaps you’re ready to move on from your commercial premises? Once the lease has been signed, you may be committed to paying rent for the full term. A break clause can provide valuable flexibility. It allows the tenant to end the lease before its contractual expiry date - which can become vital if trading conditions deteriorate, the business changes direction, or the premises are no longer suitable.
Lisa explains, “We live in a changing world where the global economy has fluctuated and can be challenging at times. Especially with a new business, your strategy may evolve. You may find that your business isn't going as well as hoped or that it would be better to let a property in a different location. But if it’s hard to get out of the lease (either by breaking it or assigning the lease to someone else), it can be very difficult for the tenant - particularly if turnover and profit aren't as high as they hoped.”
She concludes: “From the start, having the involvement of a commercial property solicitor helps to keep a positive landlord-tenant relationship. This can make such a difference in a transaction, because you know that good relationships are being fostered. It also makes it easier to negotiate the lease because trust is being built up, which is really key to achieving a smooth and positive process.”
For local businesses, a commercial lease is not simply an agreement to pay rent. It is a long-term commitment that can influence the future success of your enterprise. Getting it right from the start is a far better option than trying to renegotiate terms or manage disputes at a later date.
