The Green Homes Grant - What does it cost?


This summer the government announced a scheme where they would match fund any home improvements that made your home ‘greener’ with homeowner grants up to the tune of £5k. Great, right? At Youchitect studios we were hoping this would mean we could get some double glazing installed.


The good news is, this scheme IS great and really can help you make your home more energy efficient, which of course means cost efficient, and the government grant will help you take a step towards that. But just how far will this £5k get you? Here we dive into the detail to help you understand the scheme in full.


A Green Homes Grant is a voucher the government will give you contributiong towards the cost of installing energy efficient improvements to your home. Improvements could include insulating your home to reduce your energy use or installing low-carbon heating to lower the amount of carbon dioxide your home produces.


To qualify for the Green Home Grant and redeem your voucher you must install at least one primary measure. Then, and only then, can you use it against a secondary measure, funds permitting:


PRIMARY MEASURES:

Insulation

The following insulation measures are covered by the voucher, we’ve added range costs to each one so you know what you’re in for (costs courtesy of mybuilder.com)

  • solid wall insulation (internal or external) - £4,000-£20,000

  • cavity wall insulation - £200 for each 2 storey exterior wall you want insulating

  • under-floor insulation (solid floor, suspended floor)

  • loft insulation - £400-£500

  • flat roof insulation - £400-£1000

  • pitched roof insulation £200-£300

  • room in roof insulation

  • insulating a park home

Check the additional requirements around insulation measures

Low carbon heat

The following low carbon heating measures are covered by the voucher, we’ve annotated cost ranges supplied by tradedmencosts:

  • air source heat pump - £8,000-£17,000

  • ground source heat pump - £14,000-£20,000

  • solar thermal (liquid filled flat plate or evacuated tube collector) - £6,000-£10,000

  • biomass boiler - £10,000-£14,000

If you install one of the above primary measures you can then qualify for a secondary measure. BUT you cannot spend more on the secondary measure than you did on the primary measure. So if you want that double glazing to be subidised by the Green Homes Grant you need to invest in some pretty good insulation and/or solar heating.

SECONDARY MEASURES

Windows and doors

  • draught proofing

  • double or triple glazing (where replacing single glazing)

  • secondary glazing (in addition to single glazing)

  • energy efficient replacement doors (replacing single glazed or solid doors installed before 2002)

Heating controls and insulation

The following measures are covered by the voucher:

  • hot water tank thermostat

  • hot water tank insulation

  • heating controls (such as, appliance thermostats, smart heating controls, zone controls, intelligent delayed start thermostat, thermostatic radiator valves)

If you decide to go ahead:

  • Get 3 quotes before agreeing to any work - you need a quote from a registered installer to qualify for the voucher anyway

  • Make sure you get a receipt for the work - you will need it to redeem the voucher

  • You need separate invoices for each measure you have installed

  • Your voucher is only valid for the measure and property you applied for

  • You can only begin work once your voucher has been issued. Any work that was started before that date cannot be claimed.

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

Vouchers will be valid for 3 months from the date they are issued or until 31 March 2021 (whichever is earlier). Vouchers must be redeemed before the validity period ends. You can request a voucher extension at any time before your voucher has expired, unless the scheme has been closed.
