Who rents here
Student and young-professional shared houses around Mill Road; mandatory HMO licensing only.
Student-heavy spillover zone
Student houses and university-spillover sharers dominate from September to June. A mandatory HMO licence is needed once five or more people in two or more households share.
Coverage
What CB1 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.
CB1 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 CB1
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 CB1, 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.
Joint vs individual tenancies for student groups
Decide — and document — whether the tenancy is one joint assured tenancy signed by all sharers (one rent, joint and several liability) or individual licences per room. Mid-tenancy switches between the two are a common source of disputes and undermine deposit protection if the deposit was registered under the wrong structure.
September turnover compliance reset
Plan the certificate refresh window for August so Gas Safety, EICR and Fire Risk Assessments are not in their final 30 days at the moment a new student cohort arrives. Build a single-day turnaround plan with a contractor on call — students arriving mid-September have a strong evidence position if any safety document is out of date.

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 CB1 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.
PRS Database
When landlords in CB1 must register
CB1 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). Dates from the GOV.UK Housing Hub, checked 23 September 2026.
Get ready in LetCompliance
Seventeen answers a property. Have them on one page before 15 January 2027.
The register asks the same 17 things about every home you let, from the number of households to copies of the gas safety record, the EICR and the EPC. LetCompliance builds a register pack for each property from the records you keep in it: what is ready, what is missing, and the certificate files to upload. Registering becomes copying from one page.
A register pack for every property
All 17 items, most of them filled in from the tenancy, rent, licence and certificate records you already keep.
The gaps, said plainly
Each gap links to the page where you fill it in, so they are closed weeks ahead, not on the deadline.
Reminders on the East of England dates
An email the day registration becomes required, then 30 and 7 days before 14 Apr 2027, for every property not yet marked registered.
Included on every plan.

Common pitfalls
What goes wrong in CB1
The mistakes that recur in student-heavy spillover zone postcodes like this one.
Mid-year sub-let by departing student
A student leaving in March and “handing over” to a friend without your written consent voids your right-to-rent compliance for the new occupier. Always run a fresh check.
Holiday voids and deposit returns
Returning a full deposit before the joint tenancy formally ends costs you the deduction route if damage is later found. Hold pending the joint check-out, never per-room.
Furniture fire-safety regulation breach
Pre-1988 sofas and mattresses bought from second-hand suppliers fail the Furniture and Furnishings (Fire) (Safety) Regulations 1988 by default; replace before re-let.
FAQs
CB1: the questions landlords ask
Are short student tenancies in CB1 subject to the same Gas Safety, EICR and deposit rules?
Yes. Since 1 May 2026 a student let in CB1 is an assured periodic tenancy like any other: there is no fixed term and no assured shorthold tenancy to sign. Gas Safety (annual CP12), EICR (every 5 years), EPC band E minimum, deposit protection within 30 days and Right to Rent before move-in all apply identically. The only practical difference is timing: build your certificate refresh window for August so nothing expires inside the September turnover spike.
Does CB1 fall under selective or additional licensing in Cambridge?
No. Cambridge City Council (Mill Road) runs no selective or additional licensing scheme in CB1, 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. CB1 includes Mill Road, Romsey, Petersfield, Coleridge, Cherry Hinton. The outward code also reaches South Cambridgeshire, which is a different licensing authority.
What national UK landlord duties apply in CB1?
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 CB1 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 CB1?
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 CB1?
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 CB1 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 CB1?
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 CB1 have to register on the PRS Database?
CB1 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.
