Ask a landlord what their worst month looks like and it is rarely a bad tenant — it is an empty property. A void pays you nothing and, since the property is unoccupied, often costs you council tax on top. Two weeks empty on a £1,200 flat is not just £600 of lost rent; it is the council tax too, and it comes straight off the year's return.
Most voids are avoidable, or at least shortenable. Here is the playbook.
General guidance for landlords.
Start before the old tenant leaves
The biggest lever is timing, and it is free. The moment a tenant gives notice, or you agree an end date — the clock on the next let should start, not the day the keys come back. Advertise while the current tenant is still in (with their cooperation for viewings), line up the reference, and aim to have the next tenancy signed to start the day after the last one ends.
A property advertised the day it falls empty is already two to four weeks behind; a property advertised the day notice is served often has no void at all.
Price it to let, not to dream
An overpriced advert is the most common self-inflicted void. Every week it sits unlet costs more than the few pounds a week you were holding out for. Set the rent to what comparable local properties are actually letting at now, and remember that since the Renters' Rights Act you advertise a single asking figure, so pitch it right rather than high-then-negotiable.
If the enquiries are not coming in the first week, the price is usually the reason, not the market. Adjust early; a fast let at a fair rent beats a slow one at an optimistic one.
Keep a waiting list
Demand for a good property almost always outstrips the one tenancy you are filling. The people who enquired and viewed but missed out are the fastest way to fill your next void — if you kept their details. A waiting list of interested tenants turns this let's overflow into next let's head start, so the next void is a phone call, not a fresh advertising campaign.
Turn the property around fast
The gap between tenancies is dead time you control. Have the check-out, any cleaning and small repairs, and the safety checks lined up to happen in the first days of the void, not discovered halfway through it. A quick, honest inventory at check-in makes the check-out faster too. And after any void, run the taps and shower through before the new tenant arrives — cheap, and it clears standing water.
The landlords with the shortest voids are not lucky; they treat the turnaround as a scheduled job with a deadline, not a "when I get to it".
Keep the good tenant you already have
The cheapest void is the one that never happens because a good tenant stayed. A re-let costs you advertising, referencing, a turnaround and often a void; a renewal costs you nothing. Looking after the tenant you have — responsive repairs, a fair rent, a bit of communication — is the most under-rated void-reduction tactic there is (more on that in our tenant retention guide).
How LetCompliance helps: advertise, take applications and keep a waiting list in the same place you run the tenancy, so the moment a tenant gives notice you can re-advertise and work your list without starting cold, and the council tax and void costs land in your records, not a surprise on the next bill.

What a void actually costs
Landlords price a void as lost rent. It is more than that, and the extras are the part people forget.
On a £1,100 a month flat empty for six weeks:
Close to £1,900 out, plus the risk exposure. Against that, the cost of getting the property re-let two weeks sooner is usually a professional clean and some decent photographs.
The Renters' Rights Act shortened your warning
This is the structural change that makes voids harder to manage than they were.
Under the old fixed-term model you knew months ahead when a tenancy was ending. Since 1 May 2026 every tenancy is periodic and a tenant can give two months' notice at any time, ending on any date. Your warning window is now fixed at two months, and it can start on any day of the year.
The practical consequence is that re-letting cannot be a project you spin up when notice arrives. It has to be a standing process: photographs and a listing draft already on file, a known cleaner and handyman, referencing that runs in days rather than weeks, and a waiting list of previous enquirers you can contact the same afternoon.
Two months is enough time. It is not enough time to start from scratch.
The turnaround checklist
The gap between a three-day void and a three-week one is almost always preparation rather than luck.
On notice: confirm the end date in writing, book the check-out, ask whether the tenant will allow viewings, and relist within 48 hours using existing photographs if the property still presents well.
Two weeks before: book the clean and any known works for the day after check-out, not the week after. Line up the gas and electrical checks if either is due within three months, and settle the legionella question once — it is a risk assessment, not the certificate the sales calls imply, so the next tenancy starts clean.
Check-out day: inventory comparison, meter readings, keys, and photographs the same day. If the tenant has left belongings behind, do not simply bin them — there is a procedure, and getting it wrong is a claim.
Turnaround: clean, minor repairs and photographs inside 48 hours. Every day the property sits mid-turnaround is a day it cannot be shown.
Re-let: prioritise applicants who can move quickly and reference cleanly over the highest offer. A tenant starting two weeks sooner at £25 a month less is better money.
Turnaround stops depending on how organised you feel that week. The waiting list captures interested applicants before you need them, advertising and applications sit in the same place as referencing and the e-signed tenancy, and the next tenancy's compliance dates are already tracked. Set it up before the next notice lands; the first property costs nothing.
Frequently asked questions
How can a landlord reduce void periods?
Advertise before the current tenant leaves rather than after, price to what comparable properties actually let at now, keep a waiting list of interested tenants from previous adverts, and turn the property around fast with the check-out, cleaning and safety checks scheduled into the first days of the void. The single biggest lever is timing: a property advertised the day notice is served often has no void at all.
How much does a void period actually cost?
More than the lost rent. An empty property earns nothing and, because it has no resident, the owner usually becomes liable for the council tax too — and a furnished void can even attract a second homes premium. Two weeks empty is the rent plus the council tax, straight off the year’s return, which is why a fast re-let at a fair rent beats holding out for a higher one.
