Unpaid rent is one of the most common headaches landlords face, whether the property is a family home or a commercial unit. Arrears can build up for all sorts of reasons: a tenant loses their job, a business hits a rough patch, or a dispute over the condition of the property escalates into a refusal to pay.
Whatever the cause, the money still needs to come in, and the longer arrears are left, the harder they usually become to recover. This guide walks through the practical routes open to landlords in England and Wales, covering both residential and commercial tenancies.
The right path depends heavily on the type of tenancy, how much is owed, and whether you want to keep the tenant in place or bring the letting to an end.
Overview
A rent arrears claim is the legal process a landlord uses to recover unpaid rent from a tenant who has fallen behind on payments. It can take several forms depending on the circumstances. In some cases, the landlord simply wants the money and is happy for the tenant to stay.
In others, the arrears are severe enough that the landlord wants possession of the property back as well. The legal framework differs significantly between residential and commercial lettings. Residential tenancies, particularly assured shorthold tenancies, are governed by the Housing Act 1988 and come with strict procedural rules designed to protect occupiers.
Commercial leases are treated more as a contract between two businesses, and landlords generally have broader remedies, including the ability to forfeit the lease or use Commercial Rent Arrears Recovery (CRAR) to seize goods. In either case, getting the process right matters. A procedural slip can delay recovery by months or leave the landlord facing a counterclaim.
Key steps
Open a conversation with the tenant. Before reaching for legal remedies, speak with the tenant. A short phone call or letter asking why the rent is late often reveals a temporary problem that can be resolved through a payment plan. Keep everything in writing where possible, as it becomes evidence later.
Send a formal demand in writing. If informal contact fails, send a written demand setting out how much is owed, which rental periods it covers, and a deadline for payment. This creates a clear paper trail and signals that you are prepared to take further action if the arrears are not cleared.
Serve the appropriate notice. For residential tenancies, this usually means a Section 8 notice citing rent arrears grounds under the Housing Act 1988, or in some cases a Section 21 notice. For commercial tenancies, options include a formal demand, forfeiture, or CRAR. The notice must be drafted and served correctly to have legal effect.
Issue court proceedings if needed. If the notice period expires without payment, the landlord can apply to the county court for a possession order, a money judgment, or both. The court forms, fees, and evidence requirements vary depending on what you are asking for, so preparation is important.
Enforce the judgment. Winning the case is only half the battle. If the tenant still does not pay, enforcement options include instructing bailiffs, applying for an attachment of earnings order, or registering a charging order against property the tenant owns.
Q How much rent must be unpaid before I can start possession proceedings?
For assured shorthold tenancies, the mandatory rent arrears ground under Section 8 generally requires at least two months' rent to be outstanding at the date of the notice and the hearing. Smaller arrears can still be pursued, but under discretionary grounds where the judge has more flexibility. For commercial leases, the amount depends on the lease terms, though many include a forfeiture right once rent is a set number of days late.
Q Can I change the locks if a commercial tenant stops paying?
Peaceable re-entry is available for commercial premises in some circumstances, usually where the lease contains a forfeiture clause and the tenant is clearly in breach. It must never be used while anyone is living at the property. The process carries real risks, including waiving the right to forfeit if rent is accepted afterwards, so it is worth getting clarity before acting.
Q What is CRAR and when can I use it?
Commercial Rent Arrears Recovery (CRAR) allows a commercial landlord to instruct enforcement agents to take control of goods at the premises to recover unpaid rent. It only applies to purely commercial leases, not mixed-use properties with a residential element. A minimum amount of net rent must be outstanding, and the tenant must be given formal notice before goods can be seized.
Q Does a Section 21 notice work if the tenant is in arrears?
A Section 21 notice is a no-fault route to possession and does not require the landlord to prove arrears. It can be used even when rent is unpaid, provided the deposit rules, EPC, gas safety, and How to Rent guide requirements have all been met. However, it does not recover the money owed, so landlords often need to follow up with a separate money claim.
Q Can I claim rent arrears in the small claims court?
Yes, money-only claims for rent arrears can be issued in the county court using the money claim process. Claims under a certain threshold are usually allocated to the small claims track, which is designed to be quicker and cheaper. If you want possession as well as money, the process is different and follows the possession claim route.
Q What if the tenant has already moved out owing rent?
If the tenant has left, possession is no longer the issue, so the focus shifts to recovering the debt. A money claim through the county court is the usual route. Tracing the former tenant may be necessary, and enforcement becomes harder if they have no stable address or assets. Acting sooner rather than later improves the odds of recovery.
Q Can I deduct rent arrears from the deposit?
Yes, provided the deposit is held in a government-approved tenancy deposit scheme and the tenancy has ended. You will need to notify the tenant of the proposed deductions and evidence the arrears. If the tenant disputes the deduction, the scheme's adjudication process decides how the deposit is divided.
Rent arrears cases turn on details: the type of tenancy, what the lease says, how much is owed, and whether you want the tenant out or just the money back. An experienced legal adviser can help you think through the options based on what you describe on the call, so you know where to focus next.
