EPC Regulation Explainer for HMO Landlords
September 1, 2026
Energy efficiency has become another area where HMO landlords cannot afford to work on the basis of what was acceptable five or ten years ago. The rules are moving, the standards expected from privately rented properties are increasing, and landlords purchasing older housing stock now need to think about where that property will sit when the new EPC requirements arrive.
We have spent over 34 years developing and managing HMO properties, so we have seen plenty of regulatory changes during that time. Fire regulations have tightened, licensing standards have changed, room requirements have developed and planning has become considerably more restrictive in many parts of the country. EPC regulation is simply another part of running HMO property professionally.
For us, preparing for it has been relatively straightforward. Every HMO property we develop is already brought up to a minimum EPC C standard as part of the development process. We would rather deal with the fabric and energy performance of a property while we have it stripped back during refurbishment than sell an investor something which could require another substantial programme of works a few years later.
What are the EPC rules for landlords right now?
As things currently stand in England and Wales, domestic privately rented properties which fall within the Minimum Energy Efficiency Standards, commonly called MEES, generally cannot be let with an EPC rating of F or G unless a valid exemption applies. The existing minimum standard is EPC E.
That is the current legal position, but landlords need to look further ahead than EPC E.
The Government has now set out its policy for privately rented homes to meet EPC C, or the equivalent under the reformed EPC system, by 1 October 2030, unless a valid exemption applies. The future assessment is also changing. Rather than relying purely upon the existing EPC calculation, the proposed system uses a fabric-performance requirement alongside either a heating-system or smart-readiness metric.
The Government has also set out a proposed £10,000 per-property cost cap for meeting the future standard. Where a property still cannot reach the required standard after qualifying expenditure reaches that level, a 10-year exemption is expected to be available, subject to the rules and evidence requirements.
For an HMO investor buying a property in 2026, 2030 really is not very far away.
A property acquired now could easily still be in the same investor’s portfolio when the new standard applies. Buying an EPC D or E property because it technically complies with today’s minimum standard could therefore mean purchasing a future refurbishment bill at the same time.
HMOs have a slightly unusual position
There is an important technical distinction for HMO landlords.
Under the current Energy Performance of Buildings regime, an HMO let as an entire property can require an EPC. However, where individual rooms within an HMO are let separately, granting one of those room tenancies does not currently trigger the same requirement for an EPC for the whole building. The Government itself acknowledged this distinction in its recent work on private rented energy standards.
That position is also under review.
Government proposals specifically consider extending EPC requirements so that an entire HMO would require a valid EPC when an individual room within it is rented. The intention is to bring these HMOs within the same energy-efficiency framework as the wider private rented sector.
For a professional HMO landlord, relying on the current technical distinction would be an extremely short-term way of operating.
We develop our properties on the assumption that good quality HMOs need to meet the standards that are coming, rather than doing the minimum necessary to satisfy a particular rule today.
Why getting an HMO to EPC C is different from simply ordering another certificate
This is where older HMO stock can create a problem.
An EPC assessor cannot magically turn an inefficient Victorian or early twentieth-century property into an EPC C by producing another certificate. The underlying building has to perform.
Depending on the property, improvements can involve loft and roof insulation, wall insulation, modern heating controls, improved hot-water systems, more efficient boilers or heating equipment, upgraded windows, better doors, LED lighting and substantial work to the thermal fabric of the building.
Some properties are relatively easy to improve. Others are not.
That distinction matters enormously when buying an HMO because the inexpensive property showing an attractive headline yield can suddenly become far less attractive when £15,000, £25,000 or considerably more has to be spent bringing the building up to the standard expected over the coming years.
There can also be a practical problem with occupied HMOs. Improving the energy performance of an empty building undergoing a complete refurbishment is one thing. Trying to carry out substantial insulation, heating, window or building-fabric works around five or six paying tenants is another entirely.
Why every HMO we develop is already EPC C
Our approach is very different because we are developing the property before it enters our managed portfolio.
We have been an HMO property developer and managing agent for over 34 years. When we purchase a property for an investor, it does not receive a quick cosmetic refurbishment before being filled with tenants.
Our developments involve substantial works to the underlying property. Depending on what the building requires, that can include new electrical installations, plumbing and heating systems, insulation, plastering, windows and doors, roofing works, fire protection, ventilation and considerable alterations to the internal layout.
Energy performance therefore forms part of the development rather than becoming an afterthought.
Every HMO we develop is brought to EPC C as a minimum before it becomes part of our managed portfolio.
There is a very practical reason behind that decision. If an investor is purchasing an HMO as a long-term income-producing property, we do not want to hand them an EPC D property in 2026 and leave them wondering what additional work will be required before October 2030.
Much of the work needed to improve an EPC is substantially easier when a house is already undergoing a back-to-brick refurbishment. Walls are open, heating systems are being replaced, insulation can be addressed properly and the building can be considered as one complete project.
Doing it once makes sense.
EPC ratings matter even more with HMO running costs
Energy efficiency also has a direct commercial impact on HMO ownership which is sometimes overlooked.
Professional HMOs frequently operate with utilities included within the rent. Unlike a conventional buy-to-let where the tenant may pay their own gas and electricity bills directly, those energy costs can sit inside the HMO’s operating expenditure.
That means an inefficient building can affect the landlord’s NET return.
A high gross rental income looks considerably less attractive if excessive gas and electricity consumption is eating away at the margin every month. This is one of the reasons we have always preferred to discuss HMO investments using NET yield rather than relying upon a large gross-yield percentage that bears little resemblance to what an investor actually keeps.
Better insulation, efficient heating, sensible controls and good building fabric are therefore not simply about satisfying an EPC assessor. They form part of controlling the running costs of the business.
And an HMO absolutely should be treated like a business.
Be careful when buying readymade HMOs
The future EPC requirements create another question investors need to ask when comparing readymade HMOs.
What exactly are you buying?
A property can look perfectly presentable in photographs while hiding decades-old insulation standards, inefficient heating and poor thermal performance underneath. A new kitchen, grey carpets and six pieces of bedroom furniture tell an investor very little about the actual condition of the building.
The EPC should be checked before purchase, but investors should go further than simply looking at the letter.
Look at the recommendations. Look at how close the property is to the next EPC band. Understand what work would realistically be required to get it to EPC C and establish whether that work can be completed economically.
Buying cheaply and dealing with everything later is becoming a much harder strategy in the HMO sector.
EPC C is only one part of developing a proper HMO
We also would not suggest judging an HMO purely because it has an EPC C certificate.
A professional HMO has considerably more going on than its energy rating. Fire safety, licensing, planning, electrical installations, room sizes, amenity standards, ventilation, management, tenant demand and the actual quality of the refurbishment all matter.
This is precisely why we develop and then manage the HMO properties ourselves.
Having operated within the sector for over 34 years, we know we are going to be responsible for the property once tenants move in. Our lettings and management team will deal with its performance, maintenance and compliance long after the refurbishment photographs have been taken.
It gives us a strong incentive to build the property properly in the first place.
HMO investors should be thinking beyond 2030 already
October 2030 might sound distant when looking at an investment today. In property terms, it is extremely close.
A good HMO should be capable of producing income for decades. Investors purchasing one now should therefore be asking whether the property has been developed around yesterday’s standards or the standards likely to govern the sector during the period they actually intend to own it.
Our answer has been to get ahead of it.
Every HMO we develop is already EPC C as a minimum, and the same team that develops the property remains involved through our in-house management operation. It is part of a much wider approach we have built during more than 34 years of developing and managing HMO property.
