Is It Possible To Get Green Homes Grant for Conservatory Roofs? We tell you what you need to know about grants for conservatory roofs…

We have been swamped with questions about the Green Homes Grant Scheme, especially by those looking to get a new energy-efficient conservatory roof to replace old polycarbonate or glass roofs.

The Green Homes Grant for Conservatory Roofs information has been updated, previously there was very little information about claiming green homes grants for conservatory roofs revealed by the Government, however, we have managed to find out some which energy-saving products will be eligible for the green homes grant scheme voucher.

What is the Green Homes Grant?

The Green Homes Grant scheme is a voucher scheme aimed at helping over 600,000 homeowners in England make their houses more energy-efficient. The scheme is designed to cut energy bills whilst providing jobs for local trades that are participating in the scheme.

The Green Homes Grant Scheme is a step towards the UK’s target of zero carbon emissions by 2050, however, the scheme does not include Scotland, Wales, or Ireland. Home improvement projects that make the home more energy efficient will be included in the scheme which launched on September 1st

How much is the Green Home Grant worth?

The ‘grants’ which will be issued as vouchers worth up to £10,000. Full details on eligibility have been released, vouchers come under the following two categories:

  • Up to £5000:
    Available to homeowners and landlords to claim up to 2/3rds of the price of an energy-saving home-improvement.
  • Up to £10,000:
    homeowners on a low income can claim for 100% of the price of an energy-saving home-improvement.

    The grant will cover at least two-thirds of the cost of labour, materials, and VAT for the work
    100% of the cost is covered for homeowners on low-income.

What home-improvement projects are eligible?

To be eligible for funding, one of the two following primary measures must be installed using the grant:


  • Solid walls (Both internal or external are valid)
  • Cavity wall insulation
  • Under floor
  • Loft
  • Flat roof
  • Pitched roof
  • Room in roof
  • Park home

If your home is partly insulated already you can use the green grant to insulate the remaining parts. You can’t use the grant to remove or replace existing insulation though.

Low carbon heat

  • Air source & ground source heat pumps
  • Hybrid heat pumps
  • Solar thermal
  • Biomass boilers.

Note: Low carbon heat measures must be used for space heating-domestic hot water heating. Outdoor heating, heating of pools or process heating is not covered by the scheme.

Heat pump installations must have a minimum Seasonal Performance Factor (SPF) of 2.5.
Heat pumps of hybrid heat pump systems must provide the main source of heating demand for your home.

It’s a government requirement that biomass boiler installations must:

  • Have a valid emissions certificate for the make and model installed
  • Only use fuel that is authorised on the Biomass Suppliers List (BSL) and that has been tested for on the specific biomass boiler’s emissions certificate, for the lifetime of the installation
  • Have a valid BSL fuel number for the intended fuel
  • Only be installed in rural areas

In order to have a low carbon heat measure installed, you must:

  1. Either have planning permission, or declare that it isn’t required. Visit the Planning Portal website for planning permission.
  2. For the lifetime of the installation, the low carbon energy measures must be serviced as per the manufacturers instructions.

An adequate level of insulation is required to have low carbon heat measures installed. In order for the relevant technology to operate in line with specific standards. If you haven’t already done so, you may need to upgrade the insulation in your home.

Low carbon heat measures installed through the Green Homes Grant scheme, will also cover the costs of:

  • Any Pipework along with pumps and valves
  • Domestic hot water cylinders
    Buffer tank
  • Heating system controls
  • Underfloor heating
  • High capacity radiators

Only after having primary measures approved can you claim for secondary measures such as double glazing.

Secondary measures

You much install a minimum of 1 primary measure, your voucher can then be redeemed to cover the cost of secondary measures.

The cost of secondary measures cannot exceed the amount recieved for primary measures.

Secondary measures can only be installed once you have installed a primary measure and used the vouchers to pay for that measure.

Windows and doors

These measures are classed as secondary and are covered by the scheme:

  • Draught proofing
  • Double or triple glazing when upgrading from single glazed windows
  • Secondary glazing when being used in addition to single glazed windows
  • Energy-efficient replacement doors (replacing single glazed or solid doors installed before 2002)

All work that is covered by the voucher must be completed by a TrustMark-registered installer who is also registered to participate in the scheme.

How to apply

  1. Check your eligibility
  2. Check what energy efficiency or low carbon heat improvements may be suitable for your home
  3. Find certified installers in your area that are able to carry out the work
  4. Apply for the voucher

Getting a quote

Decided which improvements to have installed, then try to get 3 quotes from certified installers, this may not be possible but is recommended.

Only one quote needs to be provided by a Green Homes Grant registered installer so that you may apply for a voucher.

A copy of the quote will be required when you apply for a voucher. Any over-priced quotes will be rejected and the scheme administrator may request you get another quote.

One or more installers can be used to install different measures. Only one application form will need to be submitted, but a separate quote for each measure will be needed.

Vouchers are not guaranteed, do not start any work until you have been successfully awarded a voucher to cover the measures.

Getting the voucher

Vouchers will be issued to customers from early November 2020.

A separate voucher for each of the measures will be issued for you to redeem.

Vouchers are only valid for the measure and property for which it was applied. Vouchers can only be redeemed by the named applicant and are non-transferable.

Work can only commence once your voucher has been issued. If any work is started before the voucher is issued, the voucher will be void.

At the time of writing this, vouchers will be valid for 3 months from the date they are issued or until 31 March 2021 (whichever is earlier). The scheme is expected to be extended due to issues getting materials and Covid-19, this is to be confirmed.

Getting the measures installed

Once you have a voucher, the installation can begin.

Installers may ask for a deposit, this is normal and expected, however, the amount should only be what they would normally charge.

Installers cannot ask you for a deposit if you’re applying under the low-income scheme unless the cost of your measures exceeds the £10,000 value of the voucher.

Redeeming your voucher

To redeem the voucher confirmation of the following is required:

  • The installation was completed before the voucher expiry date
    You are completely satisfied with the work carried out
  • You have received documentation from the installer
  • You have paid your portion of the price to the installer

A copy of the invoice issued by the installer which must be dated will need to be supplied by you at the end of the installation.

Can I claim a green homes grant for conservatory roofs?

The answer to this is yes as long as the conservatory meets a certain specification. You CAN upgrade a conservatory roof from a Polycarbonate or old glass roof under the scheme. Green Homes Grant for Conservatory Roofs eligibility is a bit of a grey area, but the good news is that it is possible to claim a grant.

The conservatory must be classed as part of the main house, which means there can not be a door between the conservatory and the main house. Also, the conservatory should have a separate heating control to the main house in order to qualify for a Green Homes Grant for Conservatory Roof.

What is the EPC rating?

The EPC rating of a property is a measurable indicator of energy efficiency, under the green homes grant scheme, any planned home-improvement would need to noticeably improve the EPC of the property.

If you are in any doubt about your eligibility for the Green Homes Grant Scheme for conservatory roofs, windows, or doors you can contact the Green Homes Grant team.
