HMO Licensing London: The Electrical Rules Councils Actually Check

Mandatory HMO licensing applies to any HMO occupied by 5+ people from 2+ households who share facilities — applies England-wide. This is the baseline. Around 60,000 London properties hold mandatory licences.

Additional licensing is borough-discretionary and covers smaller HMOs (3-4 occupants) in designated areas. Newham, Hackney, Waltham Forest, Tower Hamlets and Croydon operate borough-wide additional schemes as of 2026. Brent, Camden, Southwark and Haringey operate partial schemes.

Selective licensing applies to all rented properties (not just HMOs) in designated areas, used by councils to tackle poor management. Newham's scheme covers the entire borough; Croydon, Waltham Forest and Tower Hamlets cover designated wards.

In practice a single property can be subject to all three regimes simultaneously, with different renewal cycles. Most portfolio landlords end up tracking licences per-property on a spreadsheet.

Every HMO licence application and renewal requires evidence of a satisfactory EICR conducted within the previous 5 years. The councils want: a clear satisfactory result, no outstanding C1 or C2 codes (or evidence of remediation), and signature by an NICEIC/NAPIT/ELECSA registered contractor.

Newham and Hackney specifically check the inspector qualification. JIB Gold Card and NICEIC contractor status are checked against the registers. An EICR signed by an unregistered electrician is rejected outright.

A common fail: EICR is technically satisfactory but C2 items were never remediated. The council asks for the minor works certificate showing the C2 remedials were done. No certificate = licence refused pending evidence.

HMOs require mains-powered, interconnected smoke and heat alarms to BS 5839-6 Grade D LD2 minimum. Grade D means mains-powered with battery backup. LD2 means coverage in all circulation areas (hallways, stairs) and all rooms of high fire risk (kitchens, living rooms).

For multi-storey HMOs (3+ storeys) the requirement steps up to Grade A LD2 — a fully addressable fire alarm system with control panel, equivalent to a small commercial system. Cost difference is significant: Grade D LD2 retrofit ~£600 for a typical 4-bed HMO, Grade A LD2 ~£2,500+.

Battery-only alarms or non-interconnected alarms are an automatic licence fail. Newham officers specifically check for the BS 5839-6 reference on the installation certificate.

HMOs require emergency lighting in escape routes. Single-storey shared houses can sometimes get away with borrowed light from streetlamps via uncurtained landing windows, but anything multi-storey needs proper BS 5266-1 emergency lighting.

Standard fit: maintained or non-maintained LED bulkheads above stairs and exit doors, 3-hour battery duration, monthly flick-test plus annual 3-hour discharge test logged in a fire safety logbook.

The Fire Risk Assessment (annual review for HMOs) must reference the emergency lighting. Hackney and Tower Hamlets routinely reject licence renewals where the FRA is silent on emergency lighting.

BS 7671 Regulation 514 requires every consumer unit to have a clear circuit schedule identifying each circuit, the date of installation/last test, and the next test due date. In HMOs the council also wants the consumer unit physically accessible — not behind a locked tenant's room door, not buried under a kitchen counter.

Waltham Forest officers specifically photograph the consumer unit during licence inspections. A board with handwritten "Ring 1, Ring 2, Lights" labels and no test dates is a common fail.

The fix is fast: a new printed schedule, a proper test date label, and if needed a relocation of the board into a communal cupboard. Combined cost roughly £180.

Newham operates the most aggressive HMO enforcement in the UK — borough-wide selective AND additional licensing, dedicated enforcement team, average inspection within 4 weeks of application. They check everything. Their licence application form has 19 evidence fields.

Hackney runs a borough-wide additional licensing scheme and has a documented preference for in-person inspections over paper evidence. Expect an officer visit within 8-12 weeks of application.

Waltham Forest combines selective (for rented properties in designated wards) with additional HMO licensing borough-wide. Tight on smoke alarm interconnection — they routinely fail Grade D installations where the interconnect link was not tested.

Croydon operates additional licensing borough-wide as of 2024 renewal. Heavy focus on fire safety: emergency lighting, alarm panel commissioning certificates, FRA quality.

Tower Hamlets runs additional licensing borough-wide and selective in designated wards (Whitechapel, Spitalfields, Bethnal Green). Strong focus on electrical evidence — their refusal letters frequently cite specific BS 7671 regulation numbers.

1. EICR remedials not evidenced. C2 items shown as outstanding without minor works certificates closing them out.

2. Smoke alarms non-interconnected or battery-only. Common in older HMO conversions where the original install was done before BS 5839-6 tightened.

3. Emergency lighting missing or not on FRA. Multi-storey HMOs without proper escape route lighting.

4. Fuse-board schedule missing, illegible, or out of date.

5. EICR signed by non-registered inspector.

6. PAT test absent on landlord-provided white goods.
