Portsmouth Landlords: PRS Database Duty Starts 15 March 2027

If you let in Portsmouth, your rental sits in the South East cohort for the PRS database (the private rented sector database under the Renters' Rights Act). Under the government's published timetable, the requirement for South East properties, including Portsmouth, starts on 15 March 2027, and you then have three months to register, by 14 June 2027. The service is currently scheduled to open to all landlords on 15 December 2026, so you can register voluntarily before the South East requirement starts. The regulations are still in draft, so these dates can still shift. Check GOV.UK before you register.

First check: is your Portsmouth let inside the city council's area?

The database rolls out by English region, and the draft regulations name Portsmouth City Council in the South East. A shared house in Southsea, a flat near the university, a terrace in Fratton or North End, or a family let in Cosham or Drayton all share the same March 2027 start and June 2027 register-by date. Your clock follows where the property is, not where you live or where your agent is based.

Not every address in the Portsmouth area is inside the city. Havant and much of Waterlooville come under Havant Borough Council, Fareham under Fareham Borough Council, and Gosport under Gosport Borough Council. Those areas sit in Hampshire, which the draft regulations also place in the South East, so the PRS database dates are the same. Local licensing and planning rules are not. Portsmouth City Council's schemes below apply only inside the city boundary, so confirm the council for each address before you work out what licence it needs.

Portsmouth is a compact coastal and naval city with a large university population. Dense terraced streets make shared housing common, and the city council runs both citywide additional HMO licensing and a citywide Article 4 Direction. That local picture sits alongside the national register: you still need whatever licence and planning permission the council requires, and you will still need to register on the PRS database once the South East window is live.

For the full England timetable see our guide to PRS database registration deadlines. For the wider picture, start with the PRS national database overview. For how local licensing and the national register interact in general, see landlord licensing explained and how to check if your property needs a licence. There is no separate South East regional blog page. Other South East city guides cover Brighton and Hove, Reading, Oxford, Southampton and Milton Keynes.

Portsmouth City Council: mandatory HMO licensing and citywide additional licensing

The PRS database is a national government register. It sits alongside, not instead of, anything Portsmouth City Council already requires locally. At the time of writing, the council's HMO licensing pages and designation document describe these layers:

• Mandatory HMO licensing for HMOs with five or more occupiers forming more than one household who share amenities such as a kitchen, bathroom or toilet, anywhere in the city (the storey test no longer applies since 1 October 2018).
• Additional HMO licensing citywide, in force from 1 September 2023 to 31 August 2028. The designation covers the whole of Portsmouth City Council's district. At the time of writing, it applies to HMOs occupied by three or four people who form two or more households (including shared houses and bedsits where occupants share amenities), certain converted buildings where a unit is not self-contained behind its own entrance door, HMOs with three or more people in a purpose-built self-contained flat in a block of three or more flats, and section 257 HMOs that are mainly or wholly tenanted (including those with resident landlords). The council explains this as buildings converted into flats that do not meet the 1991 Building Regulations, where two thirds or more of the flats are rented out. Mandatory-licensable HMOs are excluded from the additional designation because they already need a mandatory licence.

Licences can be issued for one year, two and a half years, or five years, depending on the council's criteria (for example whether safety certificates and a fire risk assessment are submitted, and whether planning permission or historic HMO use can be shown). The council's application checklist asks for a floor plan with room sizes and the location of detectors and alarms, a fire risk assessment, a gas safety certificate where relevant, a satisfactory EICR, fire alarm and emergency lighting certificates where fitted, and a PAT certificate for appliances the landlord supplies. Those are largely the same documents the national register will draw on.

No selective licensing scheme is in force in Portsmouth at the time of writing. The council's private rented licensing pages focus on mandatory and additional HMO licensing. A single-household let in the city does not currently need a council licence. Check the council's licensing pages for the live position before you rely on that for any address.

The important point for PRS database prep: a mandatory or additional HMO licence does not replace registration on the national database once the South East window is live, and registering does not replace a licence. Keep one clean compliance file per property that covers both.

Citywide Article 4 and the 10% HMO threshold

Planning is separate from licensing. Portsmouth City Council made a citywide Article 4 Direction that came into force on 1 November 2011. Since then you need planning permission to change a family house (Use Class C3) into a small HMO (Use Class C4, three to six unrelated people sharing), anywhere in the city. Larger HMOs, with more than six people sharing, fall outside the C4 class and need planning permission in any case. The council's planning pages warn that letting a Class C4 HMO to a family can change the use back to Class C3, so you may need permission again before returning it to shared use unless you hold mixed C3/C4 permission.

The council's Houses in Multiple Occupation Supplementary Planning Document (adopted in 2019) sets out how it applies Policy PCS20. A community is treated as already imbalanced where more than 10% of residential properties within a 50-metre radius of the application property are already in HMO use, and a new HMO that would tip that ratio over 10% creates an imbalance. For the purpose of that policy, Class C4, mixed C3/C4 and sui generis HMOs all count. The SPD also looks at amenity impacts such as sandwiching a family home between HMOs. Check the current document and take planning advice before you buy or convert.

If you hold a small HMO in Portsmouth, keep evidence of planning permission or lawful use (for example, proof that the property was already a C4 HMO before 1 November 2011 and has stayed in that use) in the same file as the licence. For HMO planning in general, see our guide to HMO planning and Article 4.

Portsmouth prep checklist before 15 March 2027

Use this as a working list for every Portsmouth-area let you own or manage:

• Council check: confirm whether the address is in Portsmouth City, Havant Borough, Fareham Borough or Gosport Borough, because licensing and planning follow the council even when the PRS database dates are the same.
• Gas safety (CP12): annual check where gas appliances are present, with the certificate in date, filed, and the renewal date noted.
• EICR satisfactory and still within its validity period for the electrical installation (at most five years).
• EPC valid and meeting the minimum rating the rules require for your let.
• Landlord and property details ready: your name and contact details, the property address, the type of property, the number of bedrooms, how many people and households live there, and the type of tenancy.
• Tenancy paperwork to hand: written agreement, how rent is paid, and who occupies the property (especially important for shared houses, where the number of households decides which licence applies).
• Deposit protection and prescribed information completed correctly if you took a deposit. This is a general landlord duty rather than a database field, but keep the scheme details in the same file.
• Licence details for each Portsmouth City address: mandatory HMO, additional HMO (including section 257 where it applies), or none, with the licence reference and expiry date.
• Planning evidence for shared houses: planning permission or proof of lawful HMO use under the citywide Article 4 Direction.
• Fire safety records: smoke and carbon monoxide alarms tested, and for HMOs, fire alarm test records and any fire risk assessment kept with the certificates.
• Government sign-in: watch GOV.UK for the service link and how to sign in. The service is currently scheduled to open on 15 December 2026.

None of that is new law invented for the database. It is the compliance you should already hold. The PRS database makes that compliance visible. Over time, the Renters' Rights Act also links being registered to advertising a property and to most possession claims. See why that matters in PRS database as eviction gatekeeper, and the early readiness message in when the PRS database goes live. For the wider ombudsman picture, see the PRS landlord ombudsman.

What to do between now and June 2027

1. List every Portsmouth-area property you let, including those managed by an agent, and note the council for each address.
2. Close any additional licensing gap now: if a city let has three or four sharers from two or more households and no licence or application under the 2023 scheme, deal with that before you think about the national register.
3. Check planning for shared houses against the citywide Article 4 Direction and the HMO Supplementary Planning Document before you buy, convert or add occupiers.
4. Audit certificates this winter: gas, EICR and EPC. Book renewals that would otherwise land inside the March to June registration window, when demand for engineers may be higher.
5. Bundle documents per property as digital files so registration is copy-and-paste, not a hunt across email and drawers. If you hold a council licence, keep the licence and the national registration in the same file.
6. Diary the currently scheduled dates: requirement from 15 March 2027; register by 14 June 2027. Voluntary registration is currently scheduled to open on 15 December 2026. Aim to complete registration well before mid-June, not on the last weekend.
7. Re-check GOV.UK nearer the time for the live link to the "Register your rental property" service, the fee, and any adjustment to the regional calendar, and re-check Portsmouth City Council's licensing and planning pages for any change.

A letting agent cannot register for you. The landlord makes the landlord and property entries and pays the fee (a small number of others, such as an attorney or personal representative, can act instead). An agent or property manager can supply some of the tenancy and safety details. Agree now who will provide which documents and where the certificates live.

Licence fees and the announced PRS database fee

Portsmouth landlords who hold a mandatory or additional HMO licence will feel the announced PRS database fee as another charge on the same property. For single-household lets with no council licence, it will be a new charge. That frustration is understandable. The practical response is still the same: holding a council licence does not register you on the national database, and registering does not replace a licence. A missed gas or electrical renewal can cost far more than either. Keep one clean compliance file per property so the council licence and the national register draw on the same documents.

General guidance for landlords in England, not legal advice. PRS database start dates, registration deadlines, fees, who must register, and how the service works are set by government and can change. The Private Rented Sector Database Regulations 2026 are still a draft statutory instrument, so dates can still shift. Local licensing schemes and planning rules are set by Portsmouth City Council (or by Havant Borough Council, Fareham Borough Council or Gosport Borough Council for addresses in their areas) and can change too. Always confirm the current South East dates, fee and process on GOV.UK, check licensing on the council site for your exact address, and take professional advice for your situation. LandlordProof helps you organise compliance documents and reminders; it does not make you legally compliant on its own, and it does not register you on the PRS database. You remain responsible for your legal duties as a landlord, so check GOV.UK or your council if you are unsure.
