Really Helpful

A bit of a belated reviews BUT Cucumber were great.

I was hesitant when my landlord told me that he was working with a company to get us free work on the flat but was very pleasantly surprised with how easy everything was. The work took two days, in and out and very respectful.

Would defiantly recommend.

Be careful. Check who they contract out to

My landlord decided to use this company to insulate my rental.
While Rae herself was great and tried to be as helpful as possible.
It didnt help that the company contracted out the work for my house to a company based in Scotland.
The company was awful.. A job that was supposed to take 3/4days took over 2weeks.
Communication from the company was non existant.
Promises of compensation didnt happen.
We had days of no heating in absolutw freezing temps and the care was non existant. Especially as I am a carer for my adult son and I myself am going through cancer treatment. The last thing i needed was more stress and more expense.
If a company contracts work out to others, they still bare some responsibility on how that goes and service the customer recieves. So apart from Rae who i believe tried to help.. There was little help from the company taking responsibility over the shoddy contractors they gave the work to.

I’ve been really impressed with…

I’ve been really impressed with Cucumber Eco. From start to finish, the service has been excellent.

They made the process of accessing free ECO4 energy upgrades incredibly straightforward. Communication with both us and our elderly tenant was handled really well, and the tenant is delighted with the improvements. They’re especially looking forward to the benefits this winter.

The property’s EPC rating jumped from an E to a B, which not only improves comfort and efficiency but also future-proofs the house against any upcoming EPC policy changes.

The whole experience was smooth, professional, and hassle-free. I’d highly recommend Cucumber Eco

EPC upgrades

Rae was absolutely brilliant from the very first phone call.
She updated my tenant and myself at every stage of the EPC upgrades.
Rae was very professional and courteous.
Can I thank all involved.

Fake reviews confirmed by Jonathon Mathews

I went for a interview for sales advisor role which i got offered the position, in the interview I questioned the director Jonathon Mathews with regards to there reviews on here as they looked very suspicious “yeah there all blag reviews” this company has no knowledge on eco what so ever a bunch of chancers trying to make a quick buck at someone’s misfortune. Fake reviews sets the standard for the integrity of the company

EPC upgrade Grant only for the few.....

As a good landlord with a long term excellent relationship with my elderly tenants of 18 years. I am always trying to make sure they are comfortable and any issues are dealt with. I replied to an ad for an EPC upgrade grant as my property is below the requirement for the 2030 requirements. What a disappointment to go through several phone calls and being given a positive indication of eligibility. It was only when they spoke to my tenant directly did they reveal that as the property had already got an old gas fired boiler and cavity wall insulation from the 1970's that it was therefore ineligible for the grant!
This means probably over 95% of older UK housing stock with inefficient boilers and basic very old cavity insulation would not qualify. Why did the agent not ask me that question and save me and my tenant from wasting our time and energy on calls regarding this useless scheme? Don't get your hopes up.

Reply from Cucumber Eco Solutions Ltd

Thank you for your feedback. We truly appreciate your commitment as a responsible landlord and your concern for the well-being of your tenants. We’re sorry to hear that your experience didn’t meet expectations, and we’d like to offer some clarity regarding the ECO4 scheme and our process.

The ECO4 grant eligibility process is detailed and depends on several factors, including the specific characteristics of the property, the type and age of heating systems and insulation, and the circumstances of the tenant. In your case, initial information did not include full details about the property's heating system and insulation history. As part of our due diligence, and to support landlords like yourself, our team followed up to gather this information and confirm whether the criteria were met. Our calls were intended to help rather than hinder, and had the boiler and insulation details been known earlier, we could have provided an earlier assessment.

It’s important to note that while older boilers and cavity wall insulation are indeed common, they do not automatically disqualify a property from ECO4 funding. The scheme is complex and tailored to ensure energy efficiency upgrades go to the homes and tenants that meet the government’s specific criteria. In fact:

Millions of properties in the UK are eligible under ECO4, particularly those with low EPC ratings (E, F, G) and qualifying tenants.

The scheme is funded in the billions (£4 billion+ committed between 2022–2026), specifically to help reduce energy bills and upgrade heating and insulation in qualifying homes.

There are also dedicated pathways for private landlords, especially when tenants are in receipt of certain benefits or meet other eligibility markers.

We work with both landlords and tenants to help navigate the complexity of the scheme. Our aim is always to avoid wasting anyone’s time, which is why we request key information early in the process. We're sorry this wasn’t communicated more clearly in your case, and we will take that on board for improvement.

Thank you again for your engagement and for being a landlord who looks after their tenants so well. If you have any further questions or would like us to reassess based on any updated property or tenant details, we’d be happy to assist.

Kind Regards

Cucumber Eco

Hassle free - Parents Happy :)

I just wanted to share how impressed I am with Cucumber Eco! From start to finish, the service was absolutely fantastic.

They made it incredibly easy for us to access free energy upgrades. My parents are already experiencing the benefits they promised – bills are lower, home feels so much warmer (not just in the heat wave ha ha) , and it's great knowing they have boosted the property value and future-proofed EPC.

The whole process was smooth, professional, and hassle-free. They truly stand out for making such a positive and tangible difference. Highly recommend - thx Guys.

Perfect for landlords

From the initial eligibility checks to the final installation, the entire process was smooth and straightforward, with no hidden costs. I was especially impressed that they only use certified installers, which reinforced my already high opinion of the company
