Small Commercial Landlord: Getting Started Guide

If you already know how to run a BTL, a small commercial unit feels familiar on the surface: rent in, mortgage and repairs out. But the lease is where you can either print money for 10 years or lock yourself into an expensive mistake.

1. What "commercial" actually covers

For PropertyKiln, keep it simple and use the categories agents and lenders use, plus how they sit in planning / use classes.

Retail / shops: High street units, parade shops, small shopping centre units. Typically use class E (commercial, business and service) or F.2 for small local shops.

Offices: Self-contained offices or floors in office blocks, usually class E.

Industrial / warehouses: Small industrial units, trade counters, storage, often in B2/B8 use.

Leisure / hospitality: Cafes, restaurants, gyms, pubs, small hotels, often class E or sui generis.

Mixed-use / semi-commercial: Shop with flat above, office with flats on upper floors etc; lenders call this "semi-commercial" and price it differently.

A guide aimed at you wants to keep the focus on what you will actually buy: a ground-floor shop with a flat above, a small office suite in a secondary town, or a 1,000-3,000 sq ft light industrial unit on a local estate.

2. How commercial letting is different to residential

With residential, the Housing Act and Renters' Rights Act do a lot of the heavy lifting for the tenant. With commercial, the lease does almost all of the work. If you get the lease wrong, you do not get a second chance.

Key differences to spell out:

Lease length: Commercial leases are normally 3-10 years, sometimes 15-20 years for stronger covenants. You are not talking 6- or 12-month ASTs.

Legal framework: No Housing Act 1988 or Renters' Rights protections. The key statute is Landlord and Tenant Act 1954 Part II, which gives "security of tenure" to business tenants unless you contract out.

Security of tenure: If a lease is "inside the 1954 Act", the tenant has a statutory right to a new lease when the term ends, unless you can rely on one of the statutory grounds to refuse (for example redevelopment or persistent arrears). If you "contract out", they have no automatic right to stay.

Deposits and prescribed info: No tenancy deposit protection rules, no DPS / TDS, no prescribed information. You can hold a commercial rent deposit in your own client account if the lease and deposit deed are drafted properly.

Gas / electrical checks: No specific statutory requirement for annual CP12 or 5-year EICR equivalent for commercial premises, but you owe a duty of care under general health and safety law and occupiers' liability. If someone is injured because the electrics are dangerous, you are still on the hook in negligence and under the Occupiers' Liability Acts.

Repairs: Full repairing and insuring (FRI) leases are standard. The tenant pays for most repairs and covers building insurance via the service charge or a direct recharge, rather than you doing "landlord repairs" like in an AST.

Forum myth to kill: "Commercial = no regulation. You can do what you want." Reality: You have fewer automatic tenant protections but more reliance on whatever is in your lease, plus health and safety, fire safety, asbestos and planning / use class rules in the background. The risk is not "no rules", it is "expensive litigation if you get the paperwork wrong".

3. Finding commercial tenants

The mechanics are similar to finding a good residential tenant, but with more focus on the business and its accounts.

Typical routes:

Commercial agents: High-street commercial surveyors and regional firms. Expect 8-12% of the annual rent as a letting fee on small deals, plus marketing costs (boards, listings, mail-outs).

Online portals: Rightmove Commercial, Zoopla Commercial, EG Propertylink and niche platforms. You still usually need an agent login.

Lease assignment: Many deals are assignments of an existing lease. Your current tenant finds a buyer for their lease (and maybe their business). You approve the assignee's covenant strength, sometimes keep the original tenant as guarantor, and sign a licence to assign.

Direct approaches: For local parade shops and industrial units, a board in the window or on the estate fence still works, and you can deal directly with local traders.

For forums: there is a dangerous tendency to "DIY" a commercial lease like an AST. You should flag strongly that you want a specialist solicitor on every new lease or assignment. The fees are often GBP 1,500-3,000 plus VAT for each side on small units, and that bill is cheap compared to one bad break clause or repairing clause.

4. Setting the rent and rent reviews

With commercial you are not just picking a rent, you are designing a 10-year income stream.

Market rent and comparables

You start with:

Comparable evidence: Similar units in the same parade / estate, adjusted for size, frontage, parking, condition and incentives.

Zone A for shops: For high-street retail, valuers often use "Zone A" analysis to compare rents by frontage depth. For small secondary units you can usually keep it to GBP per sq ft.

Worked example:

Secondary high-street shop in a Midlands town, 700 sq ft.

Comparable evidence: two nearby units let in 2025 at GBP 22 per sq ft and GBP 24 per sq ft.

You pitch at GBP 23 per sq ft, so GBP 16,100 per year.

Rent review mechanisms

Common structures you should spell out:

Open-market rent reviews: Every 3 or 5 years, rent is adjusted to the then-market rent, often historically on an upwards-only basis.

Index-linked reviews: Rent steps in line with RPI or CPI, often annually, sometimes with caps and collars.

Stepped increases: Rent is pre-programmed, for example GBP 14,000 year 1-2, GBP 15,000 year 3-4, GBP 16,000 year 5-6.

Turnover rents: Base rent plus a percentage of the tenant's turnover, more common in retail and hospitality.

As of early 2026, the government has brought forward plans to ban upwards-only rent reviews in new commercial leases through the English Devolution and Community Empowerment Bill. You need to flag this clearly:

New leases will have to allow rent to move up or down at market or index-linked reviews.

Fixed stepped rents agreed up-front are not caught, so you will likely see more stepped rent deals rather than traditional "upwards-only" clauses.

Forum mistake: "Just insist on upwards-only rent reviews like everyone else." For leases granted once the ban takes effect, that will be unenforceable or overridden. If you put old wording into a new lease, you risk a review clause that does not work as you expected.

5. Commercial yields and what "good" looks like

At a high level, commercial yields in 2025-26 are broadly stable, with prime assets at lower yields and secondary / tertiary at higher yields.

Typical ranges you can safely quote for small units in 2026 (freehold price vs market rent):

Prime (strong location, good tenant, long lease): 5-8% net initial yield.

Secondary (weaker town, shorter lease, more risk): 8-15% net initial yield.

Worked example:

Small industrial unit worth GBP 300,000.

Rent agreed: GBP 27,000 per year, so 9% gross yield.

After allowing GBP 3,000 per year for service charge shortfalls, management and occasional voids, net income GBP 24,000, net yield 8%.

For PropertyKiln, you should always show the net position and compare it to a realistic BTL in the same area. Many residential landlords jump to commercial for the headline yield and ignore longer voids and capex.

6. Costs of ownership

Commercial can be higher yielding because the tenant pays many of the costs. But when a unit is empty, everything lands on you.

Key cost lines to explain:

Service charge: You recover common area costs from tenants, but you often pay void shares and capital works up-front.

Insurance: Building insurance is usually recovered from the tenant via service charge or an insurance rent, but you still arrange and pay it first.

Maintenance and capex: Even on an FRI lease, you will often end up paying for structural issues, roof replacements or major plant at lease end or between tenants.

Business rates: The tenant pays during the lease. During voids, you get 3 months' empty rates relief for shops and offices, and 6 months for industrial units, then full rates unless you qualify for small business or other reliefs (2025-26 practice). That can easily be GBP 5,000-15,000 per year on a small unit in a non-prime town.

Management: Agent management fees are often 5-10% of passing rent for small commercial, plus renewal and rent review fees when those events occur.

Residential mindset mistake: assuming you only have "mortgage and insurance" to pay. On a tricky commercial unit with a long void, one year of empty rates plus insurance and service charge can wipe out three years of profit.

7. How the lease negotiation actually works

You are not signing an off-the-shelf AST. Commercial leasing is a sequence of documents and negotiations.

Typical process:

Heads of terms (HoTs): Agent sets out the key deal points: rent, term, break options, rent review pattern, repairing obligation, deposit / guarantee, assignment and subletting rules, whether the lease is inside or outside the Landlord and Tenant Act 1954.

Instruct solicitors: You and the tenant each instruct a commercial property solicitor. For even a "simple" small unit, budget GBP 1,500-3,000 plus VAT for your legal costs.

Title and enquiries: Your solicitor sends the draft lease, title, replies to CPSEs (commercial property standard enquiries). Tenant's solicitor raises questions about repairs, asbestos, fire safety, planning consent for the intended use.

Rent deposit deed vs bond / guarantee:

Rent deposit deed: Tenant pays a cash deposit (often 3-6 months' rent plus VAT) held under a deed. The deed sets out when you can draw down and how it is replenished.

Guarantee or bond: Director's guarantee on small owner-managed businesses, or a parent company guarantee on stronger covenants. Occasionally a bank bond for larger deals.

Signing and completion: Once both sides are happy, the lease and any supplemental documents (rent deposit deed, licence to alter, agreement for lease) are signed and dated.

Forum mistake: "Just download a commercial lease template and tweak it." This is how you end up with:

A lease accidentally inside the 1954 Act when you wanted to regain possession at term end.

A repairing clause that dumps 30 years of dilapidations on your first inexperienced tenant, who then fails and leaves you with a wreck and a worthless claim.

8. Insurance: what you actually need

There is no legal requirement for "commercial landlord insurance" as a label. What you need is the right mix of covers.

Core elements:

Buildings / material damage: Covers the structure for fire, flood, escape of water, storm, and other insured perils.

Loss of rent: Pays you if the building is unfit for use after an insured event and the tenant stops paying rent. You pick a sum insured based on 12-36 months' rent so you can survive a major rebuild.

Property owners' liability / public liability: Covers claims if someone is injured or property is damaged because of your building (for example a loose fascia falls on a passer-by).

Optional extras: Legal expenses, terrorism cover in some locations, glass cover where the lease makes you responsible.

The key message for a residential landlord: you cannot rely on a standard BTL policy. You need a commercial landlord or property owners policy that matches the actual use class and lease terms, or you risk the insurer declining a claim.

9. What you should know before you buy

If you are used to ASTs and HMOs, this is the reality check you need in your "should I go commercial?" guide.

You should understand and be comfortable with:

Longer voids: Normal to have 6-18 months empty between tenants on secondary units, not 4-8 weeks. Build this into your cashflow.

Tenant failure risk: One tenant often equals 100% of the income from that building. If they fail, your cashflow goes to zero overnight. Check covenant strength and accounts.

Lease complexity: The value of the property is driven as much by the lease and tenant as the bricks. A 10-year FRI lease to a strong covenant at GBP 25,000 per year can make a secondary unit worth GBP 300,000+. A vacant, tired unit might be worth GBP 150,000.

You cannot wing it: You need a commercial solicitor and surveyor. Trying to save GBP 2,000 on fees can cost you GBP 50,000+ over the term.

10. Biggest mistakes and forum myths

If PropertyKiln does nothing else, it should stop people making these three mistakes:

Ignoring the Landlord and Tenant Act 1954

Myth: "Just give them a 5-year lease and you get it back at the end."

Reality: If the lease is inside LTA 1954 and they are running a business from the premises, they have statutory security of tenure and a right to a new lease unless you can rely on specific grounds. To contract out, you must follow a set process before the lease is signed.

Over-estimating yield and under-estimating voids and capex

Myth: "My agent says 10% yield, so it is better than BTL."

Reality: If you allow 12 months' void every 5-7 years, plus empty rates and a roof replacement once in a 20-year hold, your true net yield may be closer to 6-7%.

DIY leases and no professional advice

Myth: "I can copy my mate's lease, it is only a small shop."

Reality: One bad repairing clause, break clause or rent review can knock tens of thousands off the property value or leave you with a tenant you cannot remove. This is not the place to save money.

If you were going to launch just one PropertyKiln guide for this area, the obvious starting point is: "Thinking of buying a small shop with a flat above? Here is how commercial really works and how it differs from your BTLs."
