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. Mandatory HMO rules bite the moment 5+ unrelated occupants share, and Article 4 in the surrounding postcodes restricts new HMO supply. Inspection peaks in October and February and turnover-window deposit disputes spike in July.
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 licensing type on the council checker
Open the Cambridge City Council (Mill Road) landlord licensing page, run the full postal address inside CB1, and capture a dated screenshot of the result for your records.
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 confirmed 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, IDVT 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 checker.
- 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.

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. Cambridge City Council (Mill Road) environmental health teams routinely audit student lets in October and February.
Does CB1 fall under selective or additional licensing in Cambridge?
It depends on the exact address and property type. Cambridge City Council (Mill Road) publishes a postcode or ward checker. CB1 includes Mill Road, Romsey, Petersfield, Coleridge, Cherry Hinton. The outward code also reaches South Cambridgeshire, which is a different licensing authority. Run the full postal address on the council checker before assuming no licence is required: designations are drawn by ward or street, not by postcode.
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. Get any of these wrong and Section 21, RROs and civil penalties all follow.
Is CB1 a high-enforcement postcode area?
Student, HMO-dense and regeneration postcodes in Cambridge typically see more unannounced inspections, licence audits and follow-ups from environmental health. Keep certificates, licences and tenant documents in one place and renew before expiry. Unlicensed letting can attract civil penalties up to £40,000 and Rent Repayment Orders of up to two years' rent.
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.
