Green Homes Grant Scheme

Get up to £5k towards the cost of a renewable energy product, or up to £10k if you are a lower earning home, or are receiving any form of help including … Child Tax Credits!
You will need to get in-touch with us directly so we can provide a quotation (this can be via a desktop survey). You can then apply for the grant here:, providing our TrustMark license number: 1938855.
Once the voucher has been processed we will arrange a date for installation.

The UK Government’s Green Homes Grant means that Homeowners and Landlords in England can apply for a voucher that could save you up to £600 a year on your energy bills. The voucher is used towards the cost of the installation of energy-efficient and carbon-reducing heating improvements on your home.

The voucher will cover up to two thirds for the cost of improvements to your home, the maximum value of £5,000. If you are a homeowner, and you or someone you live with receives one of the qualifying benefits, the Government will provide a higher subsidy that covers the total cost of improvements. You can receive up to £10,000 to complete the installation of energy-efficient improvements. Currently, Landlords cannot apply for the low-income part of the scheme.

Further support for low-income households can also be provided by your Local Authority through the Green Homes Grant: Local Authority Delivery. Visit GOV.UK for more information and to stay up to date on the development of the scheme.

What improvements can I carry out?

As implied by the title of the scheme, there are limitations to the work that can be carried out. Vouchers are only valid if you install at least one primary home low-carbon heating measure of home insulation.

By choosing to install at least one primary measure, you can also use your voucher to help with the cost of secondary measures. The subsidy for the secondary measure is up to the same value as the primary measure. As an example, if your primary measure uses a voucher of £1000 for the installation of a Ground Source Heat pump, then you will also receive a maximum of £1000 towards new windows and doors.

Primary Measures

Secondary Measures


  • Solid wall
  • Cavity wall
  • Under-floor insulation (solid floor; suspended floor)

Seek advice to see which primary and secondary measures will be best suited to your home.

How do I apply?

Applications for the Green Homes Grant can be made from the end of September 2020. You must be a homeowner (this includes park homeowners, long-leaseholders and shared ownership) or a Private or Social Landlord in England. Your property must also be in England, and new-build properties that have not previously been occupied are not eligible for the scheme.

To check your eligibility and to see what energy-efficient or low-carbon heat improvements can be made to your home, please contact us using the enquiry form here.

Once you have contacted us, we will be able to advise you on what improvements you can choose from for your home. We will be able to provide you with an estimate of how much the work will cost and establish a timeline for when the work can commence and finish. All work will be carried out by our team of specialists.

Can I use this voucher, even when I am receiving other types of funding?

Energy Company Obligation

If you have claimed funding from the Energy Company Obligation (ECO). In that case, you won’t be able to claim a Green Homes Grant voucher to subsidise the same improvements. However, you can claim ECO for one improvement and the Green Homes Grant to subsidise a different measure.

Renewable Heat Incentive

The Domestic Renewable Heat Incentive (RHI) is paid out over 7 years for the improvement of your homes renewable heating system. The payments are based on the amount of renewable heat that your home produces.

The good news is, you can claim both the RHI and the Green Homes Grant for renewable heat systems. Be sure to claim the Green Homes Grant either before or after applying for RHI. Make sure that you notify Ofgem that you have used it. The Green Homes Grant will then be deducted from your RHI payments.

New project sees Silvercrest Energy roll out a new Social Energy utility contract in partnership with UKPN (UK Power Networks) 

Green energy supplier Silvercrest Energy Ltd along with Social Energy, the utility supplier is launching a new project today to spur the development of a smart energy grid in southern England, working with electricity distributor UK Power Networks to enable around 100 homes to return stored energy back to the grid.

Energy customers participating in the programme will have a battery installed in their homes that will be used by the energy network to send extra power to the National grid at times of peak demand, as part of UK Power Networks’ flexibility services programme.

The project seeks to help deliver a smart grid which is better prepared for an anticipated increase in demand fuelled by zero carbon technologies like electric vehicles and electric heating, alongside the gird’s increased reliance on variable renewables.

The project will provide a glimpse into a future in which network operators buy ‘flexibility’ from companies like Silvercrest Energy who use a Social Energy artificial intelligence software, which will work with customers to balance supply and demand by using storage capacity to move demand up and down in response to levels of supply on the network. During specific periods, customer Home energy storage systems will also be available to discharge their stored energy, which will first be used to power the homeowners’ electrical appliances, with any extra being exported from the house to the grid.

Homeowners in parts of south London, Hertfordshire, and Kent will receive an annual payment of £125 for the next four years, totalling £500 in return for their participation in the project, this is alongside the extra returns a grid trading enabled home storage system already brings.

Homeowners here have an incredible opportunity to be part of this exciting project to move towards a smart grid – going green, saving money and supporting the future of energy.

Progress towards developing smart energy solutions was also made this week in the context of access to data, with south west-based electricity distributor Western Power Distribution releasing the first wave of electricity distribution network data gathered using an innovative approach known as the Common Information Model (CIM).

The CIM standardises network asset data sharing to make it more accessible, bringing together a huge range of datasets from different types of energy network infrastructure equipment, including transformers, circuit breakers, wires, and cables. The aim is to provide public access to key asset information, which stakeholders and researchers can draw on when developing smart energy technologies.

The company said low carbon technology developers could use the data to easily map WPD’s network for areas with the capacity for additional solar or wind generation, or to identify neighbourhoods which could benefit from additional flexibility through battery storage systems.

The CIM data released so far covers the South West, but plans are already in place to have the entire WPD network covered by the end of 2020, the firm said. Users will be able to access the data through WPD’s Data Hub.

Domestic Voltage optimisation

What is it? How much is it, what does it do? & a WARNING! 
Energy isn’t the same as power. If you reduce the voltage to the circuit to your kettle it will use the same amount of energy to boil the water, it will just take a little longer. The same applies to your oven heating up, or your washing machine heating the water. When used in a domestic Solar PV installation, Voltage optimisers are largely installed to compensate for the deficiencies in the poorly designed grid-tie inverters we find when retrofitting or repairing systems by others, those inverters that can’t handle the normal variations and surges in the LV distribution network.

Are solar panels worth it in the UK?

By joining over 1 million UK homeowners who have switched to solar panels for their energy, you can help to pave the way for a brighter future. The way that we use energy is changing as we move away from polluting fossil fuels. With solar panels for your home, you have the opportunity to generate your own guilt-free energy, giving you independence from the UK National Grid.

A solar panel system will generate plenty of free energy for you to use. The more solar energy you can use in the day to power your home, the less you will need to draw from the UK National Grid, saving you hundreds of pounds a year. Solar panels may also increase the value of your home; a property with a great energy efficiency rating and low energy bills is a hugely attractive feature for potential buyers.

How it works 

At first we will have to call you and book an appointment for a free, non-binding assessment of your property. The phone call will take only a few minutes of your time, during which we will explain the scheme to you, and answer any questions that you might have.

The assessment itself will take about an hour of your time, during which the assessor will ensure the property is suitable for having solar panels installed. This will involve measuring your roof etc. Our assessor will also go through your utility bills with you, calculating how much money would solar panels generate for your household in both savings and the government’s feed in tariff. We will then with your permission log onto the online portal and establish if panels can pay for themselves and benefit you.

If you are happy with the figures and would like to proceed, we will then look for a financial backer, willing to finance the system for you. The repayments would then be covered by the Feed in tariff, money for energy that you sell back to the grid and your electricity bill savings. If the system just fails to self fund you will have the option to make a small contribution if you still want solar fitted. We do warn ALL customers please don’t be disappointed if we have to say No!

But if it works and you are happy we can then proceed to installing your system. It is not a rent-a-roof scheme, which means that you become the owner of your system, receiving all of its benefits. It will have a lifespan of at least 20 years, during which it will make you £16,000 on average. 


There are a few requirements that you will have to meet in order to qualify for the scheme. If you are a homeowner but do not meet the criteria, feel free to proceed as we we might still be able to help you.  

  • Homeowner
  • Under 65 years old
  • Not moving in the next 5 years
  • No CCJs, IVAs, or debt management
  • Min. spend £40 a month on electricity
  • No loft conversions/ building work planned to the roof

SolarEdge PV Upgrade

SolarEdge power optimizers perform MPP tracking for each module individually and therefore extract the maximum energy from each module, regardless of other modules in the string.
For existing solar installations that suffer from mismatch-related power losses, SolarEdge offers two optional retrofit configurations:

Module Level Power Optimization

Add a power optimizer to each module for added energy through module-level MPPT. There is no need for additional hardware or inverter replacement.

Smart Module

In addition to power optimizers install the SolarEdge Safety and Monitoring Interface to enable:

  • Added energy through module-level MPPT
  • Enhanced maintenance through module-level monitoring
  • Automatic module level DC safety
