About the company

Energy Saving Grants helps people apply for government energy efficiency grants. The company offers free no-obligation advice on the Energy Company Obligation (ECO) Scheme and other UK grant schemes. It assists with the Energy Company Obligation (ECO), Local Authority Flex Scheme (LA Flex), Great British Insulation Scheme (GBIS), Home Upgrade Grant (HUG), and Boiler Upgrade Scheme (BUS).

Energy Saving Grants serves private homeowners, tenants, and landlords in England, Scotland, or Wales. It works with Trustmark approved installers and only works with accredited installers across the UK. The company is an official partner of One Tree Planted and funds the planting of hundreds of fruit trees in Ethiopia. It provides a free survey by a qualified retrofit surveyor. Services include solar, insulation, and heating through government grants.

What customers say

Based on genuine customer reviews

Energy Saving Grants supports households and landlords in Cardiff with solar installations, heat pumps, insulation and the grant funding that makes such upgrades feasible. The dominant theme in feedback is the quality of guidance, with customers describing how thoroughly eligibility for schemes such as ECO-4 and LA Flex was set out, and how readily questions were answered along the way.

One landlord reported that the process for fitting solar panels at two rental properties was straightforward, requiring only ownership evidence and signed permissions, while the company coordinated directly with tenants. A separate household that underwent a comprehensive upgrade, taking in an air source heat pump, a new central heating and hot water system, loft insulation and solar PV, praised the surveyors, office personnel, installers and customer liaison staff for their friendly and efficient manner, noting that calls were made ahead of scheduled appointments.

The pace of progress once entitlement was confirmed is a point that comes up often, and residents describe their homes as noticeably warmer and more comfortable afterwards. Advice on insulation eligibility for a client is also recorded, with the support provided at no cost, and Menai Heating is named as the installer that carried out the work to a professional standard from start to finish.

I would like to thank Energy Saving Grants so much for arranging the funding for our home upgrade, which we simply would not have been able to afford otherwise. I was unaware of the LA Flex scheme, and thanks to Energy Saving Grants we had loft insulation, storage heaters and solar PV installed. I highly recommend this company. Thank you.

I obtained funding via this organisation for solar panels to be installed on a couple of my rental properties, as one of the tenants said that they would qualify for a full grant. Everything went smoothly. I just had to send them some paperwork as evidence that I owned the properties and then sign some permission documents for the works to be installed. They dealt with my tenants. Overall I am very pleased and glad that I listened to my tenant.

Had a very useful chat with them. They helped me work out what insulation one of my clients was entitled to and it was all free. Great service.

We have had heat pumps, solar panels and insulation in our home – and the house is so cosy and comfortable. Menai Heating have offered a very professional service throughout, from initial contact through to completion. All people involved i.e. surveyors, office staff, installers and customer liaison were professional, friendly, efficient and polite. If an appointment had been arranged, the staff would always phone to inform us when they were planning to arrive. The sub-contractors were excellent – the insulation/plastering team, plumbers, roofers and electricians. We have no hesitation in highly recommending Menai Heating! Diolch yn fawr.

The help from Energy Saving Grants was excellent. They clearly explained the process and what we would be eligible for and were available to answer any questions. We were fortunate enough to qualify for the government ECO-4 grant and they arranged for us (via a separate company) to have installed new and high quality air source heat pump, new central heating & hot water system, solar panels, loft insulation and if it was possible, we could have had cavity wall insualtion as well, all for zero cost to us or our landlord. There are a lot of companies out there offering access to ECO-4 funding, but not all of them provide all of the options we made use of, and not all of them are totally funded. We waited approximately 3 weeks from initial enquiry until a surveyor came to our house (with Christmas in beween, so likely 2 weeks in usual conditions) and the work was all completed by the middle of March, so a total of perhaps 5 weeks once we had word that funding had been secured. The company they employed to do the work were proficient, tidy and polite and left our home in a good state (and also much warmer!!!). A lot of people arent aware of the ECO-4 funding, and often believe it to be a scam, but I can safley say that this company and the available grat is indeed genuine, so long as you are eligible. The whole process was totally hands-off for us (other than some basic form filling), so required very little time.

Fantastic from start to finish. Very quick at starting the process and I will be recommending them to my friends and family. Having bad experience from another company who gave me false expectations this company was spot on and professional
