The clock is ticking for landlords across St Helens. From 1 October 2030, the government plans for privately rented properties in England to hold a minimum Energy Performance Certificate (EPC) rating of Band C, and the penalty for non-compliance is up to £30,000 per property.
For many St Helens landlords, particularly those with older terraced homes in Parr, Sutton, Thatto Heath and the town centre, this deadline is not a distant concern. It is an active commercial priority that requires planning now, not in 2029.
The good news? Acting early means accessing funding that is closing fast, avoiding last-minute contractor queues, and positioning your portfolio to command stronger rents in an increasingly energy-conscious rental market.
Why this matters more in St Helens than most places
St Helens has a significant proportion of pre-1970s terraced housing stock, the type of property most likely to sit at EPC Band D or E. Streets across WA9 and WA10 postcodes are characterised by solid-wall and cavity-wall terraced homes that were built long before energy efficiency was a design consideration.
These properties are typically harder and more expensive to upgrade than modern stock. But they are also among the most popular with tenants, with terraced homes in WA9 available from around £100,000 and capable of delivering gross yields of up to 5.3%. The investment case for upgrading is compelling, and the compliance case is unavoidable.
The headline facts every St Helens landlord needs to know
The 2030 Band C deadline
The government has confirmed that new and existing private rental tenancies are planned to meet EPC Band C from 1 October 2030, subject to the final regulations. This applies to all landlords, whether you own one terraced house in Parr or a portfolio of properties spread across Eccleston, Newton-le-Willows and Rainford.
The cost cap
Landlords are required to spend up to £10,000 per property, or 10% of the property’s value, whichever is lower, to achieve Band C. If the required improvements exceed this cap and Band C still cannot be reached, you may be able to register a valid exemption.
The penalty for non-compliance
Fail to comply without a registered exemption, and local authorities can issue fines of up to £30,000 per non-compliant property. For a landlord with a portfolio of five or more properties, that exposure is significant.
Your step-by-step upgrade roadmap
Step 1: assess your current EPC rating
Start by locating the current EPC certificate for each of your rental properties. These are publicly searchable on the government’s EPC register. If your certificate is more than 10 years old, it will need to be renewed regardless.
Pay particular attention to properties in WA9 (Sutton, Parr) and WA10 (St Helens town centre, Thatto Heath), where older terraced stock is most likely to be rated D or E. A current assessment gives you a clear baseline and identifies exactly which measures will deliver the most improvement per pound spent.
Step 2: identify the right improvements for your property type
Not all upgrades are equal, and the right combination depends on your property’s construction type. For St Helens’ most common terraced housing stock, the most impactful measures typically include:
- Loft insulation. One of the most cost-effective upgrades available, often pushing a property up by one or two EPC bands at relatively low cost.
- Cavity wall insulation. Applicable to many post-1920s terraced homes across Parr and Sutton, and often partially or fully funded through ECO4.
- Boiler replacement. Upgrading an ageing gas boiler to a modern A-rated condensing boiler can significantly improve the heating score within the EPC assessment.
- Heat pumps. Air source heat pumps are increasingly viable for well-insulated properties and may attract additional grant support through the Boiler Upgrade Scheme.
- Smart controls and thermostats. Lower-cost additions that contribute to the new smart readiness metric introduced in the updated EPC format.
Step 3: understand the new EPC format launching October 2026
This is a critical change that many landlords are not yet aware of. From October 2026, the EPC format itself is changing. The current single-metric system, the A to G energy efficiency rating, will be replaced by a four-metric framework assessing:
- Fabric performance. How well the building retains heat through walls, roof, floors and windows.
- Heating system. The efficiency and carbon impact of how the property is heated.
- Smart readiness. The property’s compatibility with smart meters, smart controls and demand-side flexibility.
- Energy cost. The estimated running cost for a typical occupant.
This means a property’s EPC Band C status under the new format may be assessed differently from the current system. Landlords who have already achieved Band C under the old format should not assume automatic compliance under the new one. Belvoir St Helens strongly recommends seeking an updated assessment once the new framework is in place.
Step 4: act before ECO4 funding closes in December 2026
The ECO4 scheme, which funds insulation, heating upgrades and other energy efficiency measures for eligible properties, is currently scheduled to close in December 2026. This is a significant deadline for St Helens landlords with lower-rated stock, as ECO4 can cover a substantial portion of upgrade costs for properties with tenants on qualifying benefits or low incomes.
Once ECO4 closes, the funding landscape becomes less certain. Acting before December 2026 could save you thousands of pounds per property and significantly reduce the net cost of compliance.
The commercial case for acting early
Compliance is not the only reason to move quickly. Data from Belvoir’s own lettings activity shows that landlords who have already invested in energy efficiency upgrades are achieving rental premiums of up to 9% for higher-rated properties compared to equivalent Band D and E homes.
In St Helens’ competitive rental market, where tenants are increasingly aware of energy bills and running costs, a Band C or above property is a more attractive proposition. This is especially relevant given the sustained rise in energy costs over recent years, which has made EPC ratings a genuine factor in tenant decision-making.
For landlords with multiple properties across St Helens, from family homes in Rainford and Eccleston to terraced lets in Parr and Thatto Heath, a phased upgrade programme planned now can be managed strategically, spreading costs and contractor bookings across 2026 to 2029 rather than facing a last-minute scramble.
Common questions from St Helens landlords
What if I cannot reach Band C within the cost cap?
If you have genuinely spent up to the £10,000 cap and cannot achieve Band C, you can register a valid exemption on the PRS Exemptions Register. This must be documented and renewed periodically. Belvoir St Helens can help you understand whether your property is likely to qualify.
Does the deadline apply to existing tenancies?
Yes. From 1 October 2030, the Band C requirement applies to all private rental tenancies, not just new ones. There is no grace period for existing long-term tenants.
What about houses in multiple occupation (HMOs)?
HMOs are subject to the same EPC requirements. Landlords operating HMOs in St Helens should factor this into their compliance planning alongside their standard licensing obligations.
Next steps: making your portfolio EPC-ready
The 2030 deadline may feel distant, but the window for funded support and planned action is closing much sooner. With ECO4 ending in December 2026 and the new EPC format launching in October 2026, the next twelve months represent the most important period for St Helens landlords to take stock and take action.
Belvoir St Helens is here to help you navigate this with clear, practical guidance, not just compliance warnings. Whether you own one property or a growing portfolio, our team can help you understand where you stand, what upgrades are most likely to deliver compliance and rental value, and how to access available funding before it closes.
