The Home Energy Model replaces SAP from October 2026. New four-metric EPC scoring means fossil fuel heating will no longer achieve a C on the Heating System metric. Landlords who secure EPC C now under current SAP rules lock in compliance for 10 years.

Why Work With Us Instead of Going Direct to an Installer?
Many people assume the simplest route is to contact an installer directly. In reality, that approach carries significant risks that most people only discover once things have already gone wrong. Here is why working with Cucumber Eco gives you a level of protection, expertise, and efficiency that no single installer can match.
We Know Every Installer Personally
We personally know every installer in our network and have carefully vetted their qualifications, specialisms, and track record. We match your property to the right contractor from day one, so there is no guesswork, no wasted site visits, and no risk of mismatched expertise.
Specialist Matching for Every Measure
Energy retrofits require specialist skills for each measure, and using the wrong installer can mean failed inspections or clawback of funding. We assess your property, identify the full package of measures needed to reach EPC C or above, and select the best-qualified contractor for every element, coordinating multiple trades so you never have to.
We Protect You If Funding Falls Through
If a single installer loses their funding allocation or accreditation, your project can stop dead. Because we work across a wide network of approved contractors, we can switch to an alternative immediately, keeping your timeline intact without you having to restart the process.
One Point of Contact for Everything
Grants involve eligibility checks, assessments, funding applications, and compliance sign-offs, and going direct to an installer often leaves you managing that paperwork yourself. With Cucumber Eco, one team handles every step from assessment to EPC lodgement, keeping you informed throughout.
Our Core Services
What Energy Efficiency Could Save You
Estimated annual savings based on UK Energy Saving Trust and government figures. Actual savings vary by property size, usage, and existing efficiency.
EPC Band C Is Mandatory by October 2030
All privately rented properties in England and Wales must achieve at least EPC Band C. Non-compliance carries fines of up to £30,000 per property.
From October 2026, the new Home Energy Model replaces the single A-G rating with four separate metrics. Properties with fossil fuel heating will not be able to achieve Band C on the Heating System metric.
There Are Two Routes to a More Efficient Home
If your household income is £36,000 or less, or you live in a low-income area, you may qualify for a fully funded upgrade under the Warm Homes Local Grant. This government scheme covers up to £30,000 of improvements per property, including insulation, heating upgrades, solar panels, and air source heat pumps, with zero cost to you. Eligibility is based on income or postcode, not on credit history.
If you don't qualify for a free grant, you're not out of options. We can introduce you to third-party finance providers offering 0% interest plans, meaning you can spread the cost of your upgrade over time with no added interest. Finance is subject to status and provided by regulated lenders. We act as an introducer only, so there's no obligation and no hard sell.
The Warm Homes Plan is the UK government's flagship £15 billion programme to upgrade 5 million homes by 2030. Alongside this, the Boiler Upgrade Scheme offers grants of up to £7,500 towards air source heat pumps, with no income test required. Our team will assess exactly which schemes your property qualifies for before any work begins.

Frequently Asked Questions
What is the Warm Homes Plan and who qualifies?+
The Warm Homes Plan is the UK Government's flagship £15 billion scheme to upgrade 5 million low-income and fuel-poor homes to EPC C or above by 2030. You may qualify if your household income is below the area median, or if you receive a means-tested benefit such as Universal Credit or Pension Credit. Both owner-occupiers and private renters can apply.
Do I have to pay anything for a grant installation?+
No. Eligible households receive installations completely free of charge with no repayment required. Grant funding covers the full cost of qualifying measures. If you do not qualify for a full grant, we can also arrange 0% finance options through regulated lenders.
What energy efficiency improvements are available?+
Available measures include loft insulation, cavity wall insulation, solid wall insulation, solar PV panels, air source heat pumps, smart heating controls, triple glazing, ventilation systems, and first-time central heating. The specific measures recommended depend on your property type and current EPC rating.
How long does the whole process take?+
From initial enquiry to completed installation typically takes 4 to 12 weeks, depending on the scheme, measure type, and installer availability. We manage the entire timeline and keep you updated at every stage.
I am a private renter. Can I still get help?+
Yes. Private tenants in receipt of qualifying benefits can trigger a grant application. Your landlord's consent is required, but work is carried out on the property and you benefit from lower bills at no cost to you. In many cases the work can be fully funded without cost to the landlord either.
What EPC rating does my property need to be?+
Most grant schemes prioritise properties rated EPC D, E, F, or G. The aim is to bring these up to EPC C or above. If your property is already rated C or above, you may still qualify for the Boiler Upgrade Scheme or 0% finance for further improvements.
Does Cucumber Eco cover the whole of the UK?+
We operate across England, Scotland, and Wales. Grant scheme availability can vary slightly by region, and some local authority schemes may apply in your area. Contact us and we will confirm exactly what is available at your address.
What is an EPC and why does it matter?+
An Energy Performance Certificate (EPC) rates your property's energy efficiency on a scale from A (most efficient) to G (least efficient). EPCs are legally required when selling or renting a property. Landlords in England and Wales must have a minimum EPC E rating now, with EPC C required by 2030 under proposed MEES regulations. A low rating can also affect your mortgage options.
What is the 2030 MEES deadline for landlords?+
Under proposed Minimum Energy Efficiency Standards (MEES) legislation, landlords in England and Wales will need to ensure all rental properties meet EPC C by 2030. Fines of up to £30,000 per property apply for non-compliance. Acting now through grant funding can eliminate compliance costs entirely.
Is Cucumber Eco accredited and regulated?+
Yes. All installations we facilitate are completed to PAS 2030 and TrustMark standards, which are required for government-funded energy improvement schemes. Our assessors are qualified energy professionals, and we work only with vetted, accredited installers throughout the UK.
