Running a House in Multiple Occupation in the UK is no longer a matter of finding tenants and collecting rent. Licensing schemes, fire safety rules, room size limits and council enforcement teams have turned HMO ownership into a compliance exercise as much as a property business. One missed deadline, or one overlooked regulation, can mean a civil penalty of up to £30,000, a rent repayment order, or a licence refusal that stops income overnight.
This is why landlords across England, Scotland and Wales now consult firms that specialise in HMO compliance and regulatory advisory work. A capable partner reads council licensing conditions correctly, prepares evidence that satisfies environmental health officers, and keeps a portfolio ahead of changing legislation such as the Renters’ Rights Act. Below, we’ve put together a list of the top 10 HMO compliance and regulatory advisory firms operating in the UK, starting with Pearl Lemon Properties, and covering specialists in licensing, fire safety, legal defence and portfolio management. Each entry includes what the firm offers, who runs it, indicative fees and where it fits best.
The Firms We’re Covering
Here’s the shortlist we’ve reviewed for this guide, each assessed on licensing knowledge, response time, fee transparency and how they support landlords through council inspections:
- Pearl Lemon Properties
- HMO Licensing Consultants
- Landlord Licensing & Defence
- Yuno (formerly HMOServicesLondon)
- HMO Property Licensing
- The HMO Licensing Company
- HMO Advice
- The Letting Game
- Sourced Property
- OTS Solicitors
HMO Compliance Advisory Firms Explained
An HMO compliance advisory firm sits between a landlord and their local council. Instead of the landlord reading licensing conditions, fire safety guidance and Housing Act clauses alone, the firm interprets them, checks the property against them and manages the paperwork that proves compliance.
Most firms in this space cover a similar core:
- Licence applications for mandatory, additional and selective licensing schemes
- Fire safety and means of escape assessments
- Room size and amenity checks against HMO standards
- Ongoing management support once a licence is granted
- Representation during council inspections or enforcement action
The service matters because HMO regulation is not written once and left alone. Councils update licensing zones, minimum room sizes and management regulations regularly, and a firm that tracks those changes on a landlord’s behalf removes a significant amount of personal liability.
What Separates a Strong Firm From a Weak One
Not every consultancy offering “HMO advice” understands licensing law at the level a portfolio landlord needs. A firm worth engaging usually shows the following, in order of importance:
| Quality Marker | Why It Matters |
| Direct experience with local council licensing teams | Reduces delays and rejected applications |
| Fire safety and environmental health expertise | Prevents costly last-minute remedial work |
| Clear, published fee structure | Avoids disputes once work is underway |
| Ongoing compliance monitoring, not one-off fixes | Keeps a licence valid for its full term |
| Legal or barrister-level support for disputes | Protects landlords facing rent repayment orders |
| Portfolio-level reporting | Useful for landlords with more than one HMO |

Best HMO Compliance & Regulatory Advisory Firms in the UK
1. Pearl Lemon Properties
Pearl Lemon Properties leads this list because it combines HMO compliance work with the wider investment advisory support landlords actually need once a property is licensed. Rather than treating compliance as a single transaction, the team builds ongoing relationships with landlords, which means regulatory changes get flagged before they become a problem rather than after a council letter arrives.
The Service in Plain Terms
Pearl Lemon Properties reviews a property against current licensing conditions, prepares the application and supporting evidence, and stays engaged after the licence is granted so the property remains compliant for its full term. The firm also advises on investment strategy, helping landlords identify HMO opportunities that are both profitable and straightforward to license.
Regulatory Assessments: Every property is checked against the specific licensing conditions of its local authority, since requirements vary significantly between councils. This avoids the common mistake of applying a London standard to a property in Manchester or Leeds.
Investment Consulting: The team advises landlords on which HMO opportunities offer strong yield without hidden licensing obstacles, so compliance is considered before a purchase rather than after.
Ongoing Advisory Support: Licensing is not a one-off task. Pearl Lemon Properties maintains contact with clients as regulations shift, which matters given how often licensing zones and management rules are revised by councils.

Book a consultation with Pearl Lemon Properties to review your HMO portfolio against current licensing rules.
2. HMO Licensing Consultants
HMO Licensing Consultants works specifically with London landlords and brings a level of detail that few competitors can match: several of their consultants previously worked as environmental health officers. That background means they know precisely what a council inspector looks for during a visit, which shortens the path to approval.
The Service in Plain Terms
The firm consults on HMO development projects from the planning stage through to licence approval, and continues supporting landlords once a property is already licensed. Its enforcement background is used to anticipate objections before a council raises them.
Former Environmental Health Officer Insight Consultants who previously worked in council enforcement understand the small details that commonly cause applications to stall, from fire door specifications to room measurement methods.
Development Stage Guidance: Landlords converting a standard property into an HMO get support from the earliest planning stage, reducing the risk of costly changes after building work is complete.
Ongoing Compliance Support: Once a licence is granted, the firm continues to check that management regulations are being met, since a licence can be revoked for breaches that happen after approval.

| Team Size | Small specialist team |

Pricing

Best Use Case
London landlords converting a property into an HMO, or those who have received a council query on an existing licence, will benefit most from this firm’s enforcement-side knowledge.
3. Landlord Licensing & Defence
Landlord Licensing & Defence, trading as Landlords Defence, is built for the moment things go wrong. While most firms on this list focus on getting a licence approved, this one specialises in defending landlords who are already facing enforcement action, rent repayment order claims, or a licence refusal.
The Service in Plain Terms
The firm combines HMO design and licensing consultancy with access to specialist barristers who handle Housing Act disputes. Landlords facing a rent repayment order claim, a refused licence, or an unintentional HMO situation get both practical and legal support.
Barrister-Level Defence: Access to a barrister with a strong record in Housing Act law gives landlords a genuine legal defence option rather than a purely administrative service.
Rent Repayment Order Support: The firm has a documented history of reducing or defeating rent repayment order claims, including cases where tenants attempted to reclaim rent after already leaving a property.
Unintentional HMO Guidance: Many landlords do not realise a single-let property has legally become an HMO once tenants change the household composition. This firm identifies that risk before it becomes a penalty.
Company Snapshot

Best Use Case
Landlords who have received an enforcement notice, a licence refusal, or a rent repayment order claim should treat this firm as a priority call before responding to the council or a tenant’s solicitor.
4. Yuno (formerly HMOServicesLondon)
Yuno absorbed HMOServicesLondon and rebuilt the service around a technology platform that tracks licensing and compliance status across a portfolio in one dashboard. For landlords with several properties across different councils, this removes a significant amount of manual tracking.
The Service in Plain Terms
Yuno combines a compliance and licensing platform with legal and advisory support from property professionals. Landlords get a live view of licence status, upcoming renewal dates and outstanding compliance actions, backed by human advisors when a decision needs judgement rather than a checklist.
Portfolio Dashboard: Every property’s licence status, renewal date and compliance task list sits in one place, which matters for landlords managing HMOs across multiple local authorities with different rules.
Legal and Regulatory Advisory Access: The platform is backed by property litigation and data protection specialists who advise on complex tenancy and regulation questions beyond simple licensing.
Selective Licensing Alerts: As councils introduce new selective licensing schemes, such as recent expansions in Leeds, the platform flags landlords whose properties fall into a newly designated area.
Company Snapshot
| Detail | Information |
| Founder | Paul, founder of the original Yuno property compliance model (surname not publicly disclosed) |
| Established | HMOServicesLondon predates the Yuno merger; exact founding year not publicly disclosed |
| Head Office | UK |
| Coverage | UK-wide |
Pros and Cons
| Pros | Cons |
| Strong technology layer for multi-property portfolios | Less suited to landlords with a single HMO |
| Combines software with human legal advisory | Subscription pricing not published |
| Proactive alerts on new licensing schemes | Newly merged brand, so track record sits partly under the previous name |
Pricing
| Service | Indicative Price |
| Compliance checklist | Free download |
| Platform subscription | Price on request, scaled to portfolio size |
| Individual licence application support | Price on request |
Best Use Case
Landlords or letting agents managing five or more HMOs across different councils will get the most value from Yuno’s dashboard and alert system.
5. HMO Property Licensing
HMO Property Licensing runs on a straightforward model: a survey first, then a clear set of works required to reach compliance, followed by full management of the licence application with the council. Client reviews consistently mention responsiveness and follow-through on remedial work like fire doors.
The Service in Plain Terms
An expert visits the property, surveys it against the local council’s HMO standards, and provides a report on what needs to change. The firm then arranges the required tradespeople and submits the licence application, so landlords are not coordinating contractors and paperwork separately.
Compliance Survey: A structured, on-site survey identifies exactly which elements of the property fall short of council HMO standards before any application is submitted.
Managed Remedial Works: Rather than handing landlords a list of problems, the firm arranges the tradespeople needed to fix them, which is particularly useful for landlords who do not live near the property.
Full Application Handling: Once the property meets the standard, the firm manages the entire licence application process directly with the local council.
Company Snapshot
| Detail | Information |
| Founder | Not publicly disclosed |
| Established | Managing client properties since at least 2014 based on published client testimonials |
| Head Office | London |
| Coverage | London and South East England |
Pros and Cons
| Pros | Cons |
| Survey-first approach avoids failed applications | Regional focus, not a nationwide service |
| Handles contractor coordination directly | Online reviews are the main public evidence of track record |
| Positive, consistent client testimonials | Pricing for property management add-ons requires direct enquiry |
Pricing

| Licence application management | Price on request, dependent on remedial scope |
| Ongoing property management | Price on request |
Best Use Case
Landlords who suspect their property will need physical upgrades, such as fire doors or kitchen alterations, before it can be licensed will benefit from the survey-led approach here.
6. The HMO Licensing Company
The HMO Licensing Company positions itself as a one-stop provider for the full range of statutory obligations a landlord faces, not licensing alone. That includes energy performance certificates and safety certifications alongside the HMO licence itself.
The Service in Plain Terms
The firm manages HMO licensing, energy performance requirements and safety certifications as a combined service, working directly with local authorities and regulatory bodies to keep applications, inspections and renewals moving without landlord intervention at each step.
Multi-Certificate Management: Rather than sourcing separate providers for gas safety, electrical safety and energy performance certificates, landlords can consolidate these under one point of contact.
Local Authority Relationships: The firm describes ongoing working relationships with local authorities and regulatory bodies, which can smooth the inspection and renewal process.
Agent-Facing Service: Beyond individual landlords, the firm supports letting agents managing licensing obligations on behalf of multiple property owners.
Company Snapshot
| Detail | Information |
| Founder | Not publicly disclosed |
| Established | Not publicly disclosed |
| Head Office | UK |
| Coverage | UK-wide |

| UK-wide coverage | Best value likely realised only with a full compliance bundle |
Pricing
| Service | Indicative Price |
| HMO licence application | Price on request |
| Safety certification bundle | Price on request |
| Agent portfolio management | Price on request |
Best Use Case
Landlords who want a single provider to handle every statutory certificate alongside the HMO licence itself, rather than juggling separate suppliers, will find this consolidation useful.
7. HMO Advice
HMO Advice differentiates itself with a claim few competitors can make: the team are HMO landlords themselves, managing several hundred properties through a related company. That gives the advice a practical edge over firms staffed purely by engineers or fire consultants.
The Service in Plain Terms
The firm covers licensing, conversions, fire safety assessments and space planning, with investment advice layered on top for landlords considering a conversion from a standard let. A fire officer conducts the safety assessment element directly.
Landlord-Run Advisory: Because the team operates HMOs themselves at scale, the advice reflects what actually works with councils and tenants rather than theory alone.
Fire Safety Assessment: An accredited fire officer visits the property to assess compliance with fire safety regulations, recommending only reasonable and practical upgrades rather than over-specifying works.
Conversion and Investment Advice: The firm advises on converting single-let properties into compliant, high-yield HMOs, drawing on its own portfolio experience for realistic return expectations.
Company Snapshot
| Detail | Information |
| Founder | Not publicly disclosed |

| Fire safety assessment | Price on request |
| Full licensing and conversion service | Price on request |
Best Use Case
Landlords converting a family let into an HMO for the first time, who want advice grounded in real portfolio experience rather than theory, are the strongest fit.
8. The Letting Game
The Letting Game is a regional specialist based in Bristol, with over a decade of experience managing and letting HMOs specifically in that city and the surrounding South Gloucestershire area. Local knowledge is the firm’s clearest advantage.
The Service in Plain Terms
The firm handles HMO licence applications, ongoing compliance and full letting management for landlords in Bristol and the wider South West, with a dedicated compliance and licensing specialist on the team.
Bristol Council Expertise: The firm understands Bristol City Council’s specific mandatory licensing threshold and additional licensing requirements, which differ from other UK cities.
In-House Compliance Specialist: A named compliance and licensing expert on the team manages applications directly rather than outsourcing to a third party.
Full Letting and Management Service: Beyond compliance, the firm can manage the full letting cycle, from minimum room size checks through to fire safety measures and EPC requirements.
Company Snapshot
| Detail | Information |
| Founder | Not publicly disclosed |
| Established | Over 14 years of trading based on published company history |

| Full compliance and letting management | Price on request |
Best Use Case
Landlords with HMOs specifically in Bristol or South Gloucestershire will benefit most from this firm’s detailed knowledge of local licensing thresholds.
9. Sourced Property
Sourced Property operates as a nationwide property network rather than a pure compliance specialist, folding HMO licensing support into a wider investment sourcing and consulting service. This suits landlords who want compliance handled as part of a broader growth strategy.
The Service in Plain Terms
The firm helps landlords meet licensing requirements, conducts compliance audits and manages regulatory paperwork, while its investment consulting arm identifies high-yield HMO opportunities that also meet safety and licensing standards from the outset.
Compliance Audits: Existing HMOs are reviewed against current licensing conditions, identifying gaps before a council inspection does.
Investment Consulting The firm advises on HMO opportunities that are both profitable and straightforward to license, reducing the risk of buying a property that later fails compliance checks.
National Property Network: A broad industry network provides landlords access to additional resources and contacts, useful for investors scaling a portfolio across multiple regions.

Best Use Case
Investors who want compliance folded into a broader strategy for scaling an HMO portfolio, rather than a standalone licensing service, will find this a natural fit.
10. OTS Solicitors
OTS Solicitors brings a different discipline entirely: qualified legal representation. Where most firms on this list are consultancies, OTS is a solicitors’ practice, which matters significantly once a licensing dispute moves toward a tribunal or court.
The Service in Plain Terms
The firm represents landlords facing HMO enforcement action, licence refusals or revocations, and rent repayment order claims. Solicitors review the grounds for a council’s decision, identify legal avenues for appeal and negotiate directly with local authorities.
Enforcement Defence Solicitors evaluate enforcement notices, identify legal defences and negotiate with local authorities, which carries more legal weight than a consultancy response alone.
Licence Refusal and Revocation Appeals: Where a licence has been refused or revoked, the firm reviews the grounds and builds a case addressing any identified deficiencies for a formal appeal.
Landlord and Tenant Rights Advice: Beyond licensing, the firm advises on the legal rights and obligations of both landlords and tenants, reducing the risk of disputes escalating into rent repayment order claims.
Company Snapshot
| Detail | Information |
| Founder | Not publicly disclosed |
| Established | Established solicitors’ practice, exact founding year not publicly disclosed |
| Head Office | London |
| Coverage | London, with nationwide instruction by arrangement |
| Recognition | SME News UK Legal Awards, Best Immigration and Family Law Firm category |
Pros and Cons
| Pros | Cons |
| Qualified solicitors, not consultants, handling disputes | Legal fees run higher than consultancy-only services |
| Strong fit for tribunal or court-bound cases | Not focused on routine licence applications |
| Covers both landlord and tenant rights questions | London-based, though instructions accepted nationwide |
Pricing
| Service | Indicative Price |
| Initial legal consultation | From £150 |
| Hourly legal representation | From £300 per hour |
| Full appeal or tribunal case | Price on request, scaled to case complexity |
Best Use Case
Landlords already in a formal dispute with a council, or facing a rent repayment order claim in court, should treat a solicitor such as OTS as the first call rather than a general consultancy.
Which Firm Should You Choose

| Already facing enforcement or a rent repayment order | Legal defence specialist | Landlord Licensing & Defence or OTS Solicitors |
| Large portfolio across multiple councils | Technology-led tracking | Yuno |

Frequently Asked Questions
Does Pearl Lemon Properties work with my property management or accounting systems? Yes, we coordinate with your existing letting agent, managing agent or accounting setup rather than asking you to replace it.
How do you keep an HMO compliant after the licence is granted? We monitor management regulation changes and renewal dates on an ongoing basis, so compliance is maintained for the full term of the licence rather than checked once.
What reporting do I receive during the process? You receive a clear written summary at each stage, covering what has been assessed, what remains outstanding and what the council requires next.
Can you support a portfolio spread across several different councils? Yes, our team adjusts to each local authority’s specific licensing conditions rather than applying a single standard nationwide.
Do you offer a customised service for landlords with unusual property layouts? Yes, every assessment is based on the individual property, since room configuration and shared facilities vary significantly between HMOs.
How long does a typical licence application take from start to finish? Timelines vary by council, though most applications with complete supporting evidence move through the process within eight to twelve weeks.
How do you measure whether the engagement has been successful? Success is measured against licence approval, zero enforcement action during the licence term and on-time renewal, which we track and report back to you.
What happens if my property fails the initial compliance assessment? We provide a clear list of required changes and can coordinate the tradespeople needed to bring the property up to standard before resubmission.
Do you handle selective licensing as well as mandatory HMO licensing? Yes, we assess whether a property falls under mandatory, additional or selective licensing schemes, since requirements differ between them.
Is an initial consultation free? Yes, the first consultation is a no-obligation discussion to establish what your property needs before any formal engagement begins.
