If you are managing a residential tenancy in England, the end of a fixed term is not just an admin date in the diary. It is the point where you decide whether to renew, move onto a rolling arrangement, review the rent, or prepare for possession action if the tenancy is no longer working.
Getting that decision right matters because the legal framework is changing from 1 May 2026, when existing assured shorthold tenancies in the private rented sector in England are due to become assured periodic tenancies and Section 21 is due to fall away.
A lot of landlords treat this stage too casually. They assume the tenancy will just “roll on” and deal with the details later. In practice, this is where timing mistakes, paperwork gaps, and rushed notice decisions can create avoidable delay and cost. If you want a clearer view of your wider obligations as a landlord, it helps to look at the bigger picture through Atalaw Solicitors’ Landlord And Tenant service and related guidance on evidence landlords will need for possession in a post-Section 21 world.
What happens when the fixed term ends
Under the current system, where an assured shorthold tenancy ends and the tenant remains in occupation, the tenancy will often continue as a periodic tenancy. GOV.UK guidance aimed at the transition to the new regime still describes that familiar position and makes clear that the existing law remains in place until 30 April 2026.
From 1 May 2026, however, any existing assured shorthold tenancy is due to become an assured periodic tenancy automatically, and landlords will no longer be able to create private rented sector assured tenancies with an end date in the same way.
That means the question is no longer just, “Should you let this tenancy roll?” It is also, “Are you planning around the old system or the new one?” If your tenancy is ending close to the reform date, that distinction matters. It affects how you think about renewal, how you approach rent changes, and whether you still have access to the current Section 21 route at all.
When renewing still makes sense
There are still situations where a fresh agreement is sensible before the reforms take effect. If you and your tenant both want certainty for a defined period, a renewal may still suit your commercial aims.
You may prefer it because the tenant has been reliable, the property is being well looked after, and you do not want the unpredictability of a rolling arrangement in the short term.
But renewal should be a deliberate decision, not a default setting. If your real objective is only to tidy the paperwork, update the rent, or improve the tenancy file, a fresh fixed term is not always necessary.
In some cases, landlords create extra complexity by issuing a new agreement when what they really need is better record keeping, better communication, and cleaner compliance processes. At that stage, Atalaw Solicitors’ guidance on pets, deposits, and rent-related reforms and wider dispute support through civil litigation can help you think more strategically.
Re-pricing at the right time and in the right way
Rent review is one of the biggest pressure points when a fixed term ends. Before 1 May 2026, the current law still applies.
After 1 May 2026, the position changed for the private rented sector in England. GOV.UK says that from that date landlords will need to use the section 13 process for rent increases on assured periodic tenancies, using Form 4A, and they will need to give at least 2 months’ notice. It also says rent review clauses cannot be used for new rent increases after 1 May 2026, even where they appear in an existing tenancy agreement.
The practical lesson is simple. Do not blur together a discussion about rent, an informal proposal, and a legally effective rent increase. If you are re-pricing, you need to know which legal regime applies, which form or route is required, and when the higher rent can actually start. If you get that wrong, you can create a dispute where none was needed.
Service of notice is where small errors become expensive
Notice problems usually come from 1 of 3 places. The wrong route is chosen. The notice is served at the wrong time. Or the landlord cannot prove proper service later.
That last point is often underestimated. GOV.UK makes clear that the court will expect proof that notice was served correctly and that the right amount of notice was given. It specifically refers landlords to the certificate of service process and stresses the importance of keeping copies and evidence.
So if you are planning for possession, this is not the moment for vague file notes or assumptions that “the agent dealt with it”. You want a clear, dated record of:
- What was served
- When it was served
- How it was served
- Who served it
- What evidence you kept
That is where related resources such as housing disrepair services London and Atalaw’s broader material on evidence and dispute handling become relevant. Even where your main concern is possession, tenants often raise repair complaints, communication failures, or process errors as part of their defence.
The Section 21 timing issue matters right now
If you are still thinking in old-system terms, you need to keep the transition dates firmly in mind. GOV.UK states that if an assured shorthold tenancy starts on or after 1 January 2026, you will not be able to serve a Section 21 notice to bring it to an end.
It also says that if you do serve a Section 21 notice before 1 May 2026, court proceedings can only be started up to the earlier of 6 months from service or 31 July 2026. From 1 May 2026, landlords in England will instead need to rely on the new possession system and legally valid grounds.
That means a landlord who leaves decisions until the last minute can easily lose procedural options. If your property strategy depends on sale, recovery of possession, or a major rent reset, you should be planning on real dates, not general assumptions.
A sensible approach to the transition
If a fixed term is ending soon, a practical approach usually includes the following steps:
- Review The tenancy file early
- Decide Whether you want renewal, periodic continuation, or possession planning
- Separate The rent discussion from the notice decision
- Check Which legal regime applies based on the tenancy date and the 1 May 2026 transition
- Serve Documents strictly in line with the rules
- Keep Proof of service and all related communication
That kind of structure is far less glamorous than reacting at the last minute, but it usually saves time and money. It also puts you in a stronger position if the matter later becomes contested and you need help from Atalaw Solicitors through Contact Us, About Us, or related services such as debt recovery, wills, or commercial property support like commercial lease solicitors for tenants.
Final thoughts
Fixed-term to periodic transitions are no longer a minor tenancy milestone. They are a legal and commercial decision point. If you renew without thinking, increase the rent using the wrong process, or serve notice without proof, you can weaken your position very quickly.
If you want help reviewing your tenancy paperwork, planning your next step, or avoiding notice errors as the law changes, speak to Atalaw Solicitors. Getting advice before the tenancy rolls into the next stage is often far cheaper than trying to repair a weak process later.
FAQs
Do you have to issue a new tenancy agreement when the fixed term ends?
No, not always. Under the current system, many tenancies continue on a periodic basis when the fixed term expires and the tenant stays in occupation. Looking ahead, the government says that from 1 May 2026 existing assured shorthold tenancies in England will automatically become assured periodic tenancies, and landlords with an existing written record of terms will not usually need to reissue a completely new agreement just because of that legal change.
Can you increase the rent when a fixed term ends?
Possibly, but the route depends on timing and the legal framework in force. From 1 May 2026, GOV.UK says private rented sector landlords in England will need to use the section 13 process and Form 4A for assured periodic tenancies, giving at least 2 months’ notice. Rent review clauses will not be available for new rent increases after that date.
Can you still use Section 21 in 2026?
Only in limited transitional circumstances. GOV.UK says landlords cannot serve a Section 21 notice for assured shorthold tenancies that start on or after 1 January 2026, and Section 21 is due to end from 1 May 2026. Where a valid Section 21 notice is served before 1 May 2026, proceedings must still be started within the shortened transitional limits.
What is the biggest practical mistake landlords make at this stage?
Usually, it is failing to treat renewal, rent review, and possession as 3 separate decisions. Landlords often rush them together and then discover too late that the wrong form was used, the notice timing was off, or there is no proper proof of service. As the system becomes more evidence-led, that kind of gap matters more than it used to.
