HMO Licensing Barnet: Mandatory Licence Fee of £1,411 for Five or More Occupants

The mandatory HMO licensing threshold in England is set by the Housing Act 2004, as amended by the Licensing of Houses in Multiple Occupation (Mandatory Conditions) (England) Regulations 2018, which came into force on 1 October 2018. Under these rules, any property occupied by 5 or more people from 2 or more separate households — sharing a kitchen, bathroom or toilet — requires a mandatory HMO licence. Crucially, the 2018 extension removed the previous three-storey minimum, meaning a single-storey flat or bungalow in Barnet now falls within scope if the occupancy threshold is met. If you converted a property before that date and assumed you were exempt because it was not three storeys, check again immediately. Barnet Council also retains the power to introduce additional licensing schemes covering smaller HMOs, so properties with as few as 3 occupants could be captured if a selective or additional scheme is adopted in your ward.

What Does an HMO Licence Cost in Barnet?

The standard mandatory HMO licence fee in Barnet is £1,411, payable for a five-year licence period. This fee covers both the application processing and the licence itself, and is generally non-refundable once the assessment process has begun. Barnet offers a discounted fee of £1,186 to landlords who hold accreditation through a recognised scheme such as the London Landlord Accreditation Scheme (LLAS). That is a saving of £225 for a five-year period, making accreditation financially worthwhile for most portfolio landlords. Licence renewal must be submitted before expiry — there is no automatic rollover, and a gap of even 1 day between a lapsed licence and a renewed one constitutes an offence. Budget also for any required works identified at inspection: fire door upgrades, adequate bathroom provision for occupants above 5, and room size compliance can each cost several hundred to several thousand pounds depending on the property's current condition.

How Do You Apply for an HMO Licence in Barnet?

Applications are submitted online through Barnet Council's licensing portal. You will need to complete a full property declaration, provide details of all proposed occupants, and confirm that the property meets minimum room size standards. Since October 2018, the minimum bedroom size for a single adult is 6.51 square metres and for two adults sharing is 10.22 square metres. Rooms used by children aged 10 or under have a threshold of 4.64 square metres. Barnet's licensing team will assess your application and, in most cases, arrange an inspection. Processing times vary but typically run between 8 and 12 weeks for a complete application. If your application is incomplete, the clock does not start until all required information is received, so submit a thorough application first time.

What Documents Do You Need?

You will need to provide a current gas safety certificate (renewed annually), an electrical installation condition report (EICR) valid for no more than 5 years, an energy performance certificate (EPC) rated E or above, and up-to-date fire safety documentation including evidence of interlinked smoke and heat detectors. You will also need proof of public liability insurance and, where applicable, evidence of planning permission for a change of use. If you are not the freeholder, you will need consent from the head leaseholder or freeholder confirming they permit the property to be used as an HMO. Each document must be in date — an EICR more than 5 years old will cause your application to be refused at assessment.

What Happens If You Operate Without a Licence in Barnet?

The consequences of operating an unlicensed HMO are severe and have become significantly more common since enforcement powers were strengthened. A landlord found guilty of operating without a licence faces an unlimited fine in the Magistrates' Court. Under civil penalty powers introduced by the Housing and Planning Act 2016, councils can also issue fines of up to £30,000 per offence without prosecution. Barnet tenants can apply to the First-tier Tribunal for a Rent Repayment Order (RRO) covering up to 12 months of rent paid — in a typical 5-bedroom Barnet HMO renting at around £700 per room per month, that represents a potential repayment liability of £42,000. Additionally, a landlord convicted of an HMO offence may be entered onto the Rogue Landlord Database, restricting their ability to manage or own licensed property for a period of up to 5 years.

What This Means for Barnet Landlords

If you own or are acquiring an HMO in Barnet, the licensing obligation is non-negotiable and the costs of delay far outweigh the licence fee itself. The £1,411 fee, or £1,186 with LLAS accreditation, is a predictable five-year cost. A Rent Repayment Order is not. Review your current portfolio against the 5-person, 2-household threshold today, confirm whether any additional licensing schemes apply in your specific ward, and submit your application well ahead of any tenancy start date. Barnet Council's private sector housing team can advise on scheme coverage, and the LLAS accreditation process typically takes around 6 hours of online training to complete — a small commitment relative to the £225 saving and the reputational protection it provides.
