Who rents here
Mixed family and sharer demand; older terraced HMO stock.
HMO-dense + Article 4
HMO conversions and shared houses dominate the stock. Where an Article 4 Direction applies, a new C3-to-C4 conversion needs full planning permission, not permitted-development rights. HMO licensing here is the national mandatory scheme for five or more sharers: the council runs no additional scheme and no selective designation reaches this postcode, so a share of three or four needs no licence.
Coverage
What CB5 actually covers
Electoral wards touched by the outward code, from the ONS postcode directory, checked 18 September 2026. Licensing designations are drawn by ward, so this is the list to match your address against.
CB5 crosses a council boundary. It falls in Cambridge, South Cambridgeshire, and nothing Cambridge City Council designates applies to the South Cambridgeshire part of it. Check the address, not the postcode.
Before you let
The pre-tenancy checklist for CB5
Work through it before the property is advertised. One missed step can block a possession ground, trigger a Rent Repayment Order or void the insurance.
Confirm the mandatory HMO test
Cambridge City Council (Mill Road) runs no selective or additional licensing scheme in CB5, so count the people and the households: five or more people in two or more households sharing a kitchen, bathroom or toilet need a mandatory HMO licence. Keep a dated note of who lives there.
Gas Safety (CP12) - annual
Valid Gas Safety Record in place; new tenants must receive a copy before move-in and current tenants within 28 days of the check.
EICR - every 5 years
Electrical Installation Condition Report must be satisfactory. Issue C1 / C2 remedials within 28 days and keep written confirmation.
EPC / MEES - band E minimum (C by 2030)
Confirm a valid EPC and exemption status if applicable. Plan works early for the planned C-band MEES uplift by 1 October 2030.
Deposit protection within 30 days
Protect any deposit in TDS, DPS or MyDeposits and serve Prescribed Information; failure blocks most Section 8 possession grounds and unlocks tenant claims.
Right to Rent before tenancy starts
Run manual, digital (registered provider) or Home Office online checks for every adult occupier and keep dated evidence for the tenancy duration plus one year.
Fire safety for HMO / shared lets
Interlinked smoke + CO alarms, fire doors, emergency lighting on escape routes, PAT for supplied electricals and a recent fire risk assessment.
Article 4 planning check before any HMO conversion
Confirm whether the council has an Article 4 Direction in force on the date of the property’s exchange / completion. Where Article 4 applies, a C3-to-C4 conversion needs full planning permission — permitted-development rights have been removed. A retrospective application costs the same as a fresh one, and refusal can require reverting the property at your cost.
Mandatory HMO licence test
Run the mandatory test: five or more people in two or more households sharing a kitchen, bathroom or toilet. The council runs no additional scheme, so a share of three or four needs no HMO licence, though a selective designation can still cover the address. A Rent Repayment Order attaches to a licence the property needed and did not have.

What is in force across Cambridge City Council (Mill Road)
Designations are drawn by ward and sometimes by street, so a postcode is never the answer. The only authoritative source for an address in CB5 is the council’s own licensing pages.
- Mandatory HMO licensing applies where five or more people in two or more separate households share an amenity such as a kitchen or a toilet
- A purpose-built flat in a block of up to two flats also needs a licence when it is occupied as an HMO by five or more people
- The council’s licensing page sets out no additional or selective scheme, so a smaller shared house or a single-family let is not licensable in Cambridge today
- The fee is charged in two parts: £736 with the application, and £397 before the licence is granted
Typical licence fee
Mandatory HMO licence £1,133 for 2026/27, reduced to £1,000 when you apply at least eight weeks before the current licence expires
Fees are set per scheme and change between designations. Confirm the current amount on the council’s own fees page before you apply.

When landlords in CB5 must register
CB5 is in the East of England region. Registration becomes required there on 15 January 2027, and the deadline is 14 April 2027. Every let home in England goes on the new Private Rented Sector Database, and the date is set by where the property is, not where you live. Everything for the East of England.
Opens to everyone
Any property can be registered early, wherever it is.
Required in East of England
The three-month window to register starts.
Deadline
After this date the council can take enforcement action.
The fee is £65 a year for each property, pro-rated during the rollout. Miss the deadline and the council can impose a penalty of up to £7,000. While a let that should be registered is not, a court cannot make a possession order for it, except on the antisocial behaviour Grounds 7A and 14 (Renters’ Rights Act 2025, section 90).

Common pitfalls
What goes wrong in CB5
The mistakes that recur in hmo-dense + article 4 postcodes like this one.
Permitted-development misconception
Many landlords still assume a C3-to-C4 conversion is permitted development. Inside an Article 4 area it is not, and a council can require the property be reverted at the landlord’s cost.
One licence, one offence
An HMO needs one licence, mandatory or additional, never both, so a missing licence is one offence and not two. Each tenant can still apply for a Rent Repayment Order for their own rent, up to two years’ rent for an offence from 1 May 2026.
Single-deposit-for-shared-house trap
If five sharers each pay an equal deposit but it is registered as one tranche under one tenant’s name, the protection is defective for the other four — each can claim the 1–3× penalty.
FAQs
CB5: the questions landlords ask
Is CB5 subject to an Article 4 Direction for HMO conversions?
Cambridge City Council (Mill Road) runs no additional HMO scheme, so for a small HMO in CB5 the question that matters is planning. Where an Article 4 Direction covers the street, a C3-to-C4 conversion needs full planning permission rather than relying on permitted development. Confirm the exact street on the council Article 4 map: even a single road can sit just outside the designated zone.
Does CB5 fall under selective or additional licensing in Cambridge?
No. Cambridge City Council (Mill Road) runs no selective or additional licensing scheme in CB5, so the licence to check for is the national mandatory HMO licence: five or more people in two or more households sharing a kitchen, bathroom or toilet. CB5 includes Abbey, Barnwell, Newmarket Road. The outward code also reaches South Cambridgeshire, which is a different licensing authority.
What national UK landlord duties apply in CB5?
England-wide duties apply regardless of local licensing: Gas Safety (annual CP12), EICR every 5 years, EPC band E minimum (MEES), deposit protection within 30 days, Right to Rent checks before move-in, and smoke + CO alarm rules. Each carries its own fine or penalty, and a deposit left unprotected, or prescribed information never given, also stops a Section 8 possession order.
What happens if a let in CB5 needs a licence and has none?
It is an offence. For an offence from 1 May 2026 the council can impose a civil penalty of up to £40,000 instead of prosecuting, and the tenant can apply for a Rent Repayment Order of up to two years' rent. Keep certificates, licences and tenant documents in one place and renew before they expire.
How much is a landlord licence in CB5?
The fee is set by Cambridge City Council (Mill Road) for each scheme it runs, and it is usually split into an amount payable with the application and a second amount payable before the licence is granted. Some councils discount an early renewal or an accredited landlord. Where we have the current figure it is printed on the council page above; otherwise take it from the council's own fees page, because fees change between designations.
Do I need planning permission to convert into an HMO in CB5?
If the council area is subject to an Article 4 Direction for C3 to C4 use, you need full planning permission to let to 3 or more unrelated sharers. Cambridge City Council (Mill Road) publishes its Article 4 map. Large HMOs (sui generis, 7+ sharers) always need planning permission.
Can I use Section 21 in CB5 after the Renters Rights Act?
No. Section 21 was abolished on 1 May 2026 across England, including Cambridge, and every assured shorthold tenancy became an assured periodic tenancy, so possession now runs on a Section 8 ground. The deposit still matters: section 215 of the Housing Act 2004, as substituted by the Renters’ Rights Act 2025, blocks a possession order while a deposit is unprotected or the prescribed information has not been given, on every ground except 7A and 14. A missing gas record or EPC does not bar a Section 8 claim, though it is an offence in its own right and a tenant can raise it in defence of a disrepair or possession case.
What insurance should I have for a let property in CB5?
Specialist landlord buildings insurance with landlord liability (often £2m+), optional contents for furnished items, loss of rent and legal expenses. For HMOs, check the insurer explicitly covers HMO use and the number of occupants - standard buy-to-let policies often exclude HMOs.
When do landlords in CB5 have to register on the PRS Database?
CB5 is in the East of England region. Registration becomes required there on 15 January 2027, and the deadline is 14 April 2027. Any property can be registered earlier, from 15 December 2026. The fee is £65 a year for each property, and the date follows where the property is, not where the landlord lives. While a let that should be registered is not, a court cannot make a possession order for it, except on the antisocial behaviour grounds.
