The HEET Project 

We are working with local charity HEET to support residents assess their energy needs and apply for available funding. If you, or someone you know, needs additional support applying for the ECO4 scheme below, please give them a call on 020 8520 1900. 

HEET has also produced a 'Fuel Handbook' (PDF) for private tenants to support our work. This booklet has been designed specifically for renters. It will help you save money and keep your household safe and warm.

Home Upgrade Grant Phase 2

HUG 2 is a UK Government-funded scheme that aims to improve the energy efficiency of homes across England. 100% funding is available for eligible householders that own their property. We are working with the Greater London Authority to deliver this, in partnership with Everwarm, in Waltham Forest. 

The scheme can fund energy efficiency improvements including:

  • wall, loft and floor insulation
  • low carbon heating
  • solar panels

The GLA is seeking to support residents who:

  • own their home
  • have a gross household income of £36,000 per year or less OR live in a certain postcodes
  • live in a home with a low energy rating
  • live in a home with no gas central heating
  • live in a property that is an existing domestic dwelling (rather than a new build or self-built property)

We will then carry out an initial eligibility assessment and contact you within six working days. Customers will then be required to provide documentation to enable us to verify your eligibility for the scheme.

How to apply

To find out if you may be eligible to benefit from this scheme, please complete the initial application form on the Everwarm website and one of their team will be back in touch with you. 

The Great British Insulation Scheme

What is GBIS?

GBIS supports the installation of energy efficient measures, predominantly cavity wall insulation. The main objective of GBIS is to improve the least energy efficient housing occupied by low income and vulnerable households.

The scheme complements the previously delivered ECO4 scheme, yet unlike ECO4’s ‘whole house’ approach, this scheme will mostly deliver single insulation measures. In Waltham Forest, this focuses on un-insulated cavity walls. This scheme could save you hundreds a year on your energy bills, as well as helping to tackle climate change.

As well as supporting low-income and vulnerable households, it will also be available to those living in homes with an Energy Performance Certificate rating of D to G, and within Council Tax bands A to D.

If you want to find out more about this scheme, please visit Ofgem’s website.

How To Apply

We are working with two Trust mark registered GBIS Installers across the borough, depending on which ward you live in. You do not need be customers of these energy companies to apply:

For EDF: Mark House, Lea Bridge, Forest, Wood Street, Upper Walthamstow, Hoe Street, St James. High Street, William Morris, Cann Hall, Cathall, Leytonstone, Grove Green, Leyton

For Eon: Chingford Green, Endlebury, Valley, Larkswood, Hale End and Highams Park South, Hatch Lane & Highams Park North, Chapel End, Higham Hill.

GBIS is not a grant, and energy companies are able to choose which projects they want to deliver. It is up to the energy companies to determine which projects they choose to fund, the level of funding they provide, and the Retrofit coordinators and installers they choose to work with.
