Make every energy decision count across your portfolio.
Cucumber Eco helps landlords understand EPC evidence, prepare for the 2030 private rented sector standard and choose the lowest sensible cost route for each property.
Compliance starts with evidence, not a shopping list.
A generic EPC recommendation can be a useful starting point, but it is not a portfolio strategy. We look at how the property has been assessed, where default values may be depressing the result, which improvements alter the relevant metrics and which funding or finance routes are genuinely available.
Current EPC and evidence review
We read the certificate, recommendations and property context. Where assumed or not-rated values may be material, we explain whether specialist airtightness or U-value testing is worth considering.
Specialist EPC testingHeat pump and BUS suitability
Where the building, heating demand and installation design support it, an air source heat pump may improve the heating metric and qualify for an upfront Boiler Upgrade Scheme grant.
Heat pump assessmentFabric and renewable plan
For properties that need more than evidence or heating changes, we sequence insulation, solar, controls and other measures around the property rather than selling a standard bundle.
Fabric-first planningFunding, payment and finance
Some work is grant-supported, some is customer-funded and finance may be available subject to status. Every recommendation states the likely route before you commit.
Payment and finance options
Act early enough to choose the work, not merely accept it.
The government response confirms a single compliance date of 1 October 2030. Under the future standard, a property will need to meet the fabric performance metric and either the heating-system or smart-readiness metric, unless a valid exemption applies.
There is also a transition opportunity. A property with an existing-style EPC rated C or above, lodged before 1 October 2029, can be recognised as compliant until that certificate expires. That makes good evidence and timely assessment commercially important, but it does not mean every property should be rushed into the same upgrade.
- 01Review D-rated properties first and identify the gap to C.
- 02Use void periods for disruptive fabric or heating work where practical.
- 03Keep invoices, surveys, certificates and grant evidence by property.
- 04Reassess the plan when final reformed EPC implementation detail is published.
EPC regulations for landlords need a property-by-property plan.
Landlords need a clear route from the current certificate to the higher 2030 standard. The EPC, its expiry, the evidence behind the rating and the likely effect of each measure should be reviewed before a portfolio budget is committed.
Cucumber Eco connects landlord EPC planning with current MEES guidance, specialist testing, heat-pump suitability and funding checks. The aim is a defensible sequence for each rental, not a generic shopping list applied across the portfolio.
From one property to a defensible portfolio plan.
Start with the information already available. We use it to decide what deserves a site visit, what can be ruled out early and where a specialist assessment could prevent unnecessary spend.
Send the EPC
Provide the address, current certificate and any known works or constraints.
Choose the evidence
We identify the lowest-cost credible route to investigate for that property.
Confirm the scope
Testing, design, grant checks and customer-paid work are explained separately.
Sequence the portfolio
Prioritise by EPC gap, tenancy timing, available support and capital requirement.
Before you plan the spend.
Direct answers to the questions that determine whether an assessment, test or upgrade is worth pursuing.
Private rented homes in England and Wales are due to meet the higher standard by 1 October 2030, unless a valid exemption applies. The detailed evidence route depends on whether the property relies on a qualifying legacy EPC or a reformed EPC.
No universal requirement for every property to install solar or a heat pump is stated in the confirmed standard. The new approach is based on fabric performance plus either heating-system performance or smart readiness. The right measures depend on the building.
Yes. We can triage a portfolio from existing EPCs first, then focus site work on the properties where evidence, funding or technical design could materially change the plan.
The initial review is free and without obligation. If specialist testing, a new EPC, design work or installation is recommended, the scope, price, grant support and payment timing are explained before commitment.
Start with the EPCs you already have.
Send one property or a portfolio list. We will identify the most useful next assessment and explain what should wait.
