Green Deal


The Green Deal helps you make energy-saving improvements to your home and find the best way to pay for them.

How it works

The cost of improvements is repaid by a charge on the household’s electricity bill. Interest will be charged on these payments at a fixed rate.

Green Deal improvements can only be installed after an impartial assessment by a certified Green Deal Assessor and can only be recommended if they meet the ‘Golden Rule’ that estimated savings from improvements should be greater than the cost over the lifetime of the loan. As an example measures that may be financed through the Green Deal* for a typical 1890's terraced house could include:

  • Loft insulation
  • Draught proofing
  • Hot water tank insulation
  • Solid wall insulation
  • Boiler replacement

The Green Deal Cashback Scheme is a first-come, first-served offer where householders in England and Wales can claim Cashback from Government on energy saving improvements like insulation, front doors, windows and boilers. View further information on the Green Deal Cashback Scheme.

If you're carrying out Green Deal work, from assessment to installation, you must be Green Deal certified and use the Green Deal quality mark.

You're advised to look out for the Green Deal approved quality mark which proves assessors and installers are government registered.

The Energy Saving Advice Service can also confirm valid assessors on 0300 1231234.

Assessments must follow a standard method and any Green Deal Certified company can install the improvements, not just the company making the assessment.

Permission Click to get info

Both the building owner and all affected occupiers have to approve any Green Deal improvements before they can go ahead. In the case of flats, all households and the building owner need to give permission for measures that affect the whole building. The permission of the council or housing association will be required before their tenants can make Green Deal improvements to properties.

Planning Permission

Listed building consent or other planning approvals may be required for works undertaken as part of Green Deal. Such consents, if required, must be obtained prior to the undertaking of any works.

For works concerning single residential dwellings guidance is available from our duty planning officer service on 020 8496 3000. General planning guidance can be found here.

Building regulation approval may also be required for works to ensure buildings remain safe after works.

You may qualify for help with insulation or other energy efficiency measures dependant on the type of property that you live in, where it is located and if you are on certain benefits.

The council is working to promote and encourage uptake of energy efficient retrofit in each borough. This will mean cosy homes in winter and lower energy bills for residents. The overall UK market value of retrofit is estimated at over £500 billion.

The council wants to build upon and support existing local supply chains that deliver this work with the aim of growing the local green economy and developing an SME and labour market that can be exported beyond North London.

The North London Retrofit SME Network is:

  • A directory of SME builders and installers who deliver retrofit services located in the boroughs of Waltham Forest, Camden, Enfield, Haringey, Islington and Newham
  • A forum to hear from local SMEs how councils can support locally delivered retrofit in North London
  • A networking opportunity for SMEs working in the area
  • It aims to strengthen links with local training providers, and
  • Sign post local retrofit SMEs towards the different initiatives offering support and training in this growing market both locally and London wide

The DECC Green Deal Pioneer Places funded the initial development of RetrofitWorks cooperative. The cooperative is a network of small to medium enterprises specialising in refurbishment and energy retrofit services and other local partners that aim to deliver reductions in energy use, carbon emissions and ultimately lower spend on utility bills while stimulating the local economy and improving the health and well-being of residents.

It is owned by its members, experienced local builders, installers, energy advisers, architects and other building professionals – that are fully trained including PAS 2030 accreditation.

Membership can include local authorities, community groups and other organisations that wish to promote retrofit and refer customers to a high quality service. The cooperative aims to develop a trusted, reliable and complete retrofit service for residents who want to make their homes more comfortable.

As RetrofitWorks is a Cooperative, any full trading members own a share in the cooperative. RetrofitWorks are inviting organisations to sign up to become members now. To find out more about RetrofitWorks: The Good Building Cooperative please visit
