EPC Guide for Shortlets in London: How It Affects Rental Performance, Operating Costs, And Future-Proofing

An Energy Performance Certificate (EPC) is a rating that assesses a property’s energy efficiency and environmental impact in the UK. While EPC and Minimum Energy Efficiency Standards (MEES) requirements vary for London short-term rentals, improving energy performance can lower utility costs, enhance guest comfort, and help future-proof your investment.

Key Takeaways:

• London short-term rentals require a valid EPC, but whether the MEES and future EPC Band C proposals apply will depend on how the property is used and the type of tenancy arrangement.
• Energy-efficiency improvements can lower utility bills, elevate guest comfort, improve reviews, and strengthen future rental income potential.
• Short-term rentals should meet EPC standards due to tighter regulations, rising operating costs, and evolving market expectations.
• An early start to EPC compliance will help short-lets with cost planning and improvement schedules without disrupting rental operations.
• Structured planning with a property management expert can help ensure smoother, cost-efficient compliance.

Most residential rental properties require a valid EPC before they can be rented out. However, whether Minimum Energy Efficiency Standards (MEES) apply to every type of short-term holiday accommodation depends on how the property is used and the tenancy arrangement. Landlords should check the latest EPC guide from GOV.UK or seek professional advice to determine if your property is compliant with current regulations.

EPC Guide for Shortlets: Why Is It Important in London

Knowing the latest Energy Performance Certificate (EPC) guide for shortlets should be part of your strategy in 2026. While much of the discussion around EPC reform focuses on the long-term rental sector, short-term accommodation providers should also seek to understand how evolving energy-efficiency standards affect operating costs, property value, guest experience, and future regulatory changes.

With the looming EPC C-rating compliance deadline on 1 October 2030, landlords should focus on the government’s ongoing efforts to refine implementation guidance, such as modernising the framework through the Home Energy Model (HEM), which is expected to roll out in late 2029.

While the October 2026 deadline seems far off, many regulations under the Renters’ Rights Act will be implemented in the next few years. Last-minute compliance might cost you more or lead to mistakes that could compromise your property’s earning potential.

Early compliance matters, especially for London landlords, for four reasons.

• Changing regulations and future-proofing. While the government’s Guidance on Dwellings reveals how holiday properties fall outside the scope of MEES, understanding your property’s current EPC performance helps you to prepare for future policy changes while ensuring compliance with any regulations that do apply to your specific letting model.
• Rising operational costs. Shortlets have higher operating costs than longlets because the owner pays utility bills. With the rising energy costs, these bills can impact profitability. By being more energy-efficient, you can protect your profit and minimise operational costs.
• Evolving market expectations. Guests are more eco-conscious now, and they prefer sustainability and comfort. Improving your property’s EPC rating translates to better heating, insulation, and a higher-quality stay.
• Better EPC ratings improve guest experience. Unlike long-term landlords, short-let hosts pay their own utility bills. A more energy-efficient property heats up faster, stays warmer in winter, remains cooler during summer, and consumes less electricity between guest stays. Guests enjoy improved comfort, while owners benefit from lower operating costs and fewer complaints.

EPC compliance should not be treated as a legal requirement. It should be part of your strategy to improve your shortlet’s performance in London. By maintaining a high-performing rental property, you can stand out in London’s competitive short-let market.

What is the Latest EPC Guide for Shortlets in London?

The latest EPC guide for shortlets includes practical updates to help property owners make energy-efficient improvements strategically. The Just Landlords survey revealed that energy-efficiency upgrades cost £7,633 to £12,000. You need to approach this with a plan, so it won’t deplete your resources. The goal is that, if you have to spend, make sure it delivers the most significant energy-efficiency improvement.

Did you know:

As of March 2026, 3.38 million privately rented homes across England would require improvements to achieve an EPC rating of C, according to a Just Landlords survey. The Ministry of Housing is actively monitoring compliance through the Live Tables on Energy Performance of Building Certificates, as upgrade costs are expected to approach nearly half (50%) of the total annual rental income.

What do you need to know about the EPC regulations?

First, your short-let is not legally required to achieve an EPC rating of C by 1 October 2030. However, if you want the flexibility to switch to long-term letting, you’ll need to meet this target to avoid getting fined for non-compliance, should you decide on a long-term tenancy agreement.

To protect long-term landlords from excessive upgrading costs, the government enforces a maximum £10,000 cost cap. Once you’ve invested in qualifying efficiency upgrades to this limit and can provide receipts of the work done from 1 October 2025 onwards, you can register a cost-cap exemption to shield your property for 10 years. Since short-term rentals fall outside the 2030 requirement, this exemption cap does not apply to holiday hosts.

These regulations govern properties uniformly across England and Wales, not just London. Regardless of your current rental strategy, always keep clear records of your expenses to demonstrate compliance.

What this means for London shortlets

Even if short-lets fall outside the proposed EPC Band C requirements, investing in energy efficiency can improve operating margins today. It lowers utility bills without compromising guest comfort, increasing the chances of positive reviews or repeat bookings.

For London short-let owners, specifically those in older Edwardian and Victorian buildings, there’s practical value in improving your property’s EPC. Your property will enjoy better insulation, efficient heating systems, and smarter controls to reduce utility costs. You won’t just help guests feel more comfortable. You’ll also make your property more competitive on booking platforms by highlighting sustainability features.

Meeting EPC standards will also prepare your property for future changes, such as if you suddenly want to get a long-term tenant. You don’t have to spend on improving your EPC ratings because you’ve already done it.

What Should Short-Term Landlords Do Now to Comply?

With the updates on the EPC rules, London property owners should start planning and taking steps to lift their rating to C. Here are tips to get you started.

Assess your current EPC rating

Review your current EPC rating. The farther you are from a C rating, the more work needs to be done.

Once you’ve confirmed your rating, find out what improvements are needed to make it a C. List the improvements and research the cost estimate to get them done. This will give you a ballpark figure of the expense.

Plan cost-effective improvements

Use your list of improvements to find cost-effective options. Among the upgrades you might need, the cost estimate is as follows:

• Improved insulation
  • Floor: £1,200 to £5,500
  • Internal wall: £7,000 to £10,000
  • External wall: £10,000 to £16,000
  • Cavity wall: £1,600 to £3,500
  • Loft: £600 to £1,000
• Energy-efficient heating systems or boilers: 
  • New or replacement gas boiler £1,200 to £5,000
  • Heat pump: £7,000 to £14,000
• Double-glazed windows: £400 to £1,500 (per window)
• Smart heating controls: £79 to £300+

It’s important to remember that costs vary depending on the property’s age, construction type, and location. London properties, especially converted flats, listed buildings, and period homes, often require solutions that may be more expensive than the national average. Make sure you choose the best option for your property without exceeding the £10,000 cost cap.

Check whether you qualify for government support

Government grants are available to help landlords fund energy-efficient upgrades. Depending on your property’s eligibility and current government schemes, you can get financial support to reduce upgrade costs.

Examples include:

• Boiler Upgrade Scheme (BUS): Offering upfront grants of £7,500 for heating systems.
• Warm Homes (Local Grant Schemes): Regional funding from local councils, offering up to £15,000 to £30,000 per property for low-income tenants or deprived postcodes.
• Energy Company Obligation (ECO4): Extended until 31 December 2026. Where large energy suppliers provide funding to vulnerable, low-income households.

Because funding programmes change regularly, make sure you check the current GOV.UK guidance before planning any upgrades.

Phase improvements over time

Once you have the list of improvements and the cost implications, schedule the upgrades. Find out what improvement is most urgent so you can prioritise.

The high-impact improvements for short-lets include:

• Smart-heating controls
• LED lighting throughout the property
• Draught proofing
• Double glazing where appropriate
• Efficient boilers or heat pumps
• Loft insulation
• Thermostatic radiator valves

Unlike purely compliance-driven improvements, these upgrades often generate immediate savings through lower utility bills while enhancing guest comfort throughout the year.

Maintain compliance records

Every installation or improvement should be documented accordingly. File these together with your other compliance records.

Keep all receipts of qualified upgrades so you can file and track them as part of the cost cap. Note the dates on which installations and improvements are made. These will not just help you keep track, but also tell you when the next maintenance (or at least inspection) should be scheduled.

Consider professional compliance support

Managing a rental property while ensuring compliance requires attention to detail and time. To ensure day-to-day operations don’t make you forget compliance schedules, partner with a professional to handle bookings, maintenance, and guest communication.

A property management company like City Relay can help landlords:

• Assess current EPC performance
• Prioritise high-impact improvements
• Coordinate with trusted contractors
• Schedule upgrades around guest bookings
• Maintain accurate and up-to-date compliance records
• Develop phased improvement plans based on property type and rental strategy
• Minimise disruption to occupancy during upgrades

At City Relay, we schedule upgrades and improvements during the lean season to ensure properties are fully operational during London’s peak tourist season. We also use Opago, a smart proprietary platform to monitor compliance records, renewals, and updates. Property owners can use this platform to stay on top of maintenance schedules.

Our team also helps landlords identify energy-efficiency improvements that deliver the greatest operational benefit for flexible lets, balancing guest comfort, lower utility costs, property value, and future regulatory resilience.

Upgrading A Typical London Flat

Imagine having a one-bedroom Victorian flat in London with an EPC rating of D. Among the possible recommendations to improve the rating to C would be as follows:

• Loft insulation: £800
• Smart heating controls: £250
• Draught proofing: £300
• Boiler replacement: £3,000

In total, the property owner will spend £4,350 just to meet the Band C rating. Instead of completing the updates in one year, the owner can focus on the insulation and heating controls first. Prioritising this will reduce the property’s winter energy consumption between guest stays while creating a warmer, quieter apartment with fewer temperature-related complaints from guests. The draught proofing can follow after.

This approach will give the owner more time to save for the boiler replacement, which is the most expensive upgrade. Spreading the work over several years allows the property to elevate energy efficiency and guest comfort, without requiring lengthy block-out dates that may compromise peak-season booking potential.

EPC Compliance: Plan Early to Perform Better

For short-term rental owners, an EPC should be viewed as a practical roadmap for improving your property’s performance and not just a regulatory document. Better insulation, efficient heating, and lower utility costs can improve guest comfort, reduce operating expenses, and strengthen a property’s competitiveness in an increasingly sustainability-focused rental market.

Whether your property falls within the proposed EPC Band C requirement or not, investing in energy efficiency today can improve both profitability and future flexibility.

Although the 2030 deadline is still a couple of years away, you can position yourself to be compliant as early as now. If you want to understand how this will affect your rental income, contact City Relay. We can discuss your options and help you plan a schedule to meet current EPC requirements without delay.
