Which certificates do I need for an HMO licence?

Councils commonly expect a written fire risk assessment for the communal parts under the Regulatory Reform (Fire Safety) Order 2005, a legionella risk assessment or water-hygiene evidence under HSWA 1974, COSHH 2002 and HSE ACoP L8, a satisfactory EICR, and a gas safety record where gas appliances are present. Exact requirements depend on the local licensing scheme.

Do HMOs need a fire risk assessment?

Yes in practice. As Responsible Person under the Regulatory Reform (Fire Safety) Order 2005 you must have a suitable and sufficient assessment for the communal parts, recorded in writing and kept under review. Licensing teams may query thin downloaded DIY templates.

How much do an HMO fire risk assessment and legionella risk assessment cost?

As a guide, a legionella risk assessment for an HMO or more complex residential system is typically £150–£350. A fire risk assessment for a small HMO is typically £180–£350, rising to about £350–£750 for larger or more complex sleeping-risk premises. Final prices depend on size, layout and access, and are confirmed by the matched assessor.

Is an EICR mandatory for HMO licensing?

Under the Electrical Safety Standards in the private rented sector you need a satisfactory EICR. Some councils also ask for PAT where appliances are supplied. Treat electrical evidence as supporting paperwork alongside your fire and legionella documents.

What happens if I operate an unlicensed HMO?

Operating a licensable HMO without a licence is an offence under section 72 of the Housing Act 2004. In England councils can prosecute (an unlimited fine on conviction) or issue a civil penalty, and for offences from 1 May 2026 tenants or the council can seek a Rent Repayment Order for up to two years' rent (previously 12 months). Missing certificates can also hold up an application.

Can I do my own FRA or legionella assessment for licensing?

The law requires the assessment to be carried out by a competent person. For sleeping-risk HMOs most landlords appoint a professional. Appointing an assessor does not transfer your legal duty, but it normally produces a more defensible report.

Q: Do I need a legionella risk assessment for an HMO?

Yes. Shared water systems, multiple outlets and higher tenant turnover raise the risk. The duty sits under section 3 of the Health and Safety at Work etc. Act 1974 and COSHH, with ACoP L8 as the practical code. Licensing teams often ask for proof of a water-hygiene assessment.

Which certificates do you need for an HMO licence? In practice most English and Welsh councils expect a written fire risk assessment for the communal parts under the Regulatory Reform (Fire Safety) Order 2005, plus a legionella risk assessment (or clear water-hygiene evidence) under section 3 of the Health and Safety at Work etc. Act 1974, the COSHH Regulations 2002 and HSE ACoP L8. Gas safety (CP12) is required where gas appliances are present, and a satisfactory EICR is normally expected. Exact lists vary by council scheme, but fire and water hygiene are the documents licensing teams most often query first.

Safety Certificates UK is a matching network: we introduce independent assessors and do not assess in-house. Lists also vary by whether you are under mandatory, additional or selective licensing, so always check your council’s current scheme conditions (see GOV.UK: HMO licences). This guide sets out the usual core pack, why FRA and legionella come first, typical costs, and the penalties for letting without a licence.

The cost of operating unlicensed

Letting a licensable HMO without a licence is an offence under section 72 of the Housing Act 2004. If your application stalls because of missing certificates and you keep letting the property, the consequences can be severe. In England the council can prosecute (an unlimited fine on conviction) or issue a civil penalty, and in serious cases seek a banning order.

Tenants, or the council, can also apply for a Rent Repayment Order (RRO). Under the Renters’ Rights Act 2025, for offences committed on or after 1 May 2026 an RRO can cover up to two years’ rent, with two years to apply; earlier offences stay capped at 12 months (GOV.UK RRO guidance). Rules in Wales differ, so check with your council.

1. Fire risk assessment (FRA) — primary

This is where many HMO landlords fail their applications. For a standard single-let, working smoke alarms may be enough. For an HMO, you are typically the Responsible Person under the Regulatory Reform (Fire Safety) Order 2005 for the communal parts.

You must be able to produce a comprehensive, written fire risk assessment. Licensing teams may query basic downloaded DIY templates. Expect the assessment to cover, among other things:

Fire doors: Do bedrooms and the kitchen have suitable fire doors with intumescent strips and self-closers where required?
Compartmentation: Are there gaps where fire could spread between floors or rooms?
Detection and escape: Interlinked alarms to an appropriate grade/category for the property, clear escape routes, and thumb-turn or easy egress on final exits.

For housing premises, ask whether the assessment is aligned to BS 9792:2025 rather than the withdrawn PAS 79-2 pathway. As a guide, an FRA for a small HMO is typically £180–£350, and about £350–£750 for larger or more complex sleeping-risk premises. See FRA costs in 2026.

2. Legionella risk assessment — primary

This requirement catches many HMO landlords off guard. Under the HSE’s ACoP L8 framework, dutyholders must assess and manage Legionella risk. HMOs are heavily targeted because they often have more complex plumbing (multiple en-suites) and higher tenant turnover.

Empty rooms create void periods where water can stagnate — a recognised Legionella risk factor. A proper legionella risk assessment by a competent person typically traces pipework, measures hot and cold temperatures, and identifies dead legs and other risk factors. Licensing teams often ask for proof of a water-hygiene assessment. The legal duty comes from section 3 of HSWA 1974 and the COSHH Regulations 2002, and the practical code is ACoP L8 (see also HSE: landlords’ responsibilities). As a guide, a legionella risk assessment for an HMO or more complex residential system is typically £150–£350.

3. Gas safety certificate (CP12) — where applicable

If your HMO has a gas boiler or gas appliances, you must provide a valid Gas Safety Certificate, renewed every 12 months by a Gas Safe registered engineer. A copy is often displayed in a communal position. This sits in the pack; it does not replace your FRA or legionella duties.

4. Electrical Installation Condition Report (EICR) — supporting

Under the Electrical Safety Standards in the private rented sector, you need a satisfactory EICR. Many councils also expect more frequent testing for HMOs because of higher usage and turnover. C1 or C2 faults typically need remedial action within strict timescales (commonly 28 days for serious codes).

Some councils also ask for PAT where you supply appliances. Treat EICR/PAT as important supporting evidence — not the primary product we sell through this portal. For electrical work, use a suitably qualified electrician; for fire and water hygiene, use our matching network.

The “competent person” trap

To save money, landlords often attempt FRA or legionella assessments themselves. For many licensed HMOs that is a false economy. Councils may ask for evidence that assessments were carried out by someone competent for the premises. If a DIY assessment misses a critical flaw, you still carry Responsible Person / dutyholder liability — hiring a professional does not “transfer” that legal duty away, but it does give you a defensible, usable report.

Safety Certificates UK matches vetted assessors nationwide; we do not assess in-house and we do not claim UKAS, BAFE or ISO accreditation for the portal itself.

How to prepare your HMO licence application

Check local council variations — While FRA and legionella are the usual pillars, your scheme may demand extra PAT, room-size evidence or specific alarm grades.
Book competent assessors — Use our nationwide matching network for fire and legionella. Ask for BS 9792:2025 alignment on housing FRAs where in scope.
Close remedial actions, then submit — Fix critical findings, then submit clean reports with floorplans and the application fee.

Missing certificates for your HMO licence?

Do not risk rejection or a Rent Repayment Order. Bundle fire and legionella into one coordinated enquiry where it helps.
