Commercial property development in the UK involves layers of legal work that can easily catch out anyone approaching a deal without proper support. Whether you are buying a site for redevelopment, taking a long lease on a trading unit, or investing in an existing portfolio, the legal groundwork tends to determine whether the project runs smoothly or stalls in disputes.
I'm Brad Askew, and I've spent years working in and around civil and commercial law. On this page I want to walk you through the practical role solicitors play across a commercial property project, what to expect at each stage, and where it usually pays to get a second opinion before committing.
The goal is simple: help you understand the moving parts so you can brief your own adviser properly, ask sharper questions, and avoid the mistakes that most often show up after contracts have been signed.
Overview
When people talk about 'commercial property solicitors' they usually mean lawyers who handle the legal side of non-residential real estate work in England and Wales. That covers a wide spread of work: buying and selling freehold sites, granting and taking business leases, acting on development finance, dealing with planning and construction contracts, and resolving disputes between landlords, tenants, developers and neighbours.
The work sits at the intersection of property law, contract law, planning law, and tax. A solicitor's job is to make sure the deal does what the client thinks it does, that title is clean, that the documents reflect the commercial terms agreed, and that obligations going forward are understood.
On a larger scheme you may also see specialist construction, planning, and tax lawyers involved alongside the main property team. Costs, timing and regulatory compliance all depend on the specifics, so the legal support you actually need will vary from one project to the next.
Key steps
Early scoping and heads of terms. Before instructing a solicitor formally, most parties agree outline commercial terms, often in a heads of terms document. A solicitor will look at these, flag anything that does not work legally, and make sure subject-to-contract protections are in place so nobody is bound too early in the process.
Title investigation and due diligence. The solicitor reviews the Land Registry title, searches, replies to enquiries, and any existing leases or rights affecting the property. This is where restrictive covenants, rights of way, environmental issues and adverse entries come to light, and where the buyer decides whether the price and plans still make sense.
Planning and development consents. Development work almost always engages the Town and Country Planning Act 1990 and related regulations. The solicitor checks existing permissions, any planning conditions, section 106 obligations, community infrastructure levy exposure, and whether the proposed use is consistent with what has actually been authorised for the site.
Drafting and negotiating the main documents. This covers contracts for sale, transfers, leases, agreements for lease, options, overage agreements, and construction documents. Each carries its own risk allocation. The solicitor works through repair, insurance, rent review, break rights, alienation, and service charge provisions line by line against the client's commercial priorities.
Completion and post-completion compliance. Once contracts exchange and complete, the solicitor handles SDLT returns, Land Registry applications, notices to landlords or management companies, and registration of charges at Companies House where needed. Missing any of these steps can undermine the client's legal position later on.
Q Do I actually need a solicitor for a commercial property deal?
Commercial property transactions are not regulated in the same consumer-friendly way as some other areas of law, which means you are largely expected to know what you are signing. Most buyers, sellers, landlords and tenants instruct a solicitor because the documents are long, the obligations can last for decades, and unwinding mistakes after completion is expensive. For anything beyond a very short, simple arrangement, legal support is the norm.
Q How is a commercial lease different from a residential tenancy?
Commercial leases sit under a different legal framework, largely governed by the Landlord and Tenant Act 1954 and freely negotiated terms rather than the statutory protections given to residential tenants. Rent reviews, repair standards, service charges, break clauses and security of tenure all need to be negotiated. Tenants often have fewer default protections, so what is written in the lease genuinely matters.
Q What does security of tenure mean under the 1954 Act?
Business tenants who occupy for the purposes of their business generally have a statutory right to renew their lease at the end of the term, unless the lease has been contracted out of the relevant parts of the Landlord and Tenant Act 1954 before completion. Whether a lease is inside or outside this regime is one of the most important points to check before signing.
Q What is a section 106 agreement?
A section 106 agreement is a planning obligation entered into with the local planning authority under the Town and Country Planning Act 1990. It typically ties the benefit of a planning permission to financial contributions or specific works, for example affordable housing, highways improvements or public open space. The obligations run with the land, so later owners inherit them.
Q How long does a commercial property transaction take?
Timescales vary enormously. A straightforward lease of an existing unit might complete in a few weeks, while a development site purchase conditional on planning can take many months or longer. Searches, finance, planning, and the number of parties involved all affect the timetable. Anyone quoting a fixed timeline without seeing the papers is usually guessing.
Q What taxes typically apply on a commercial property purchase?
Stamp Duty Land Tax usually applies on freehold purchases and on the grant or assignment of leases in England and Northern Ireland, with different rules and rates in Scotland and Wales. VAT may also be chargeable depending on whether the seller has opted to tax. Rates and thresholds change, so always check the current position on gov.uk before budgeting.
Q What is overage and when does it come up?
Overage, sometimes called clawback, is a contractual right for a seller to receive an additional payment if a future event increases the value of the land, typically the grant of planning permission for a more valuable use. It is common on development land sales and needs careful drafting, because poorly worded overage clauses are a frequent source of later disputes.
