Looking to make your home more comfortable and cheaper to live in?
Don’t know where to start?
This page will help set you in the right direction.

An Installer Network is currently being developed by Severn Wye Energy Agency (SWEA) across Wiltshire, Stroud and South Gloucestershire.

N.B.  Announcement from DECC, 24th July 2014  Applications to the Green Deal Home Improvement Fund have now closed. Due to overwhelming popular demand, the Green Deal Home Improvement Fund is closed for applications with immediate effect. A recent surge in applications  means the allocated budget has now been reached. All applications received prior to the fund closing that satisfy the terms and conditions and meet the eligibility criteria will be honoured at the original rates.

In General

The Energy Saving Trust web-site is a must. This site helps you understand energy use and conservation, energy saving retrofit options, will direct you to trusted suppliers/installers and help find access to funding schemes for your project: Energy Saving Trust 

More locally

The Centre for Sustainable Energy (CSE) in Bristol has a wealth of experience.

Wiltshire Council provides basic energy advice for free and has details of local programmes and grant schemes that may save you money if retrofitting (subject to eligibility criteria and availability): Wiltshire – Home Energy Efficiency

If you’re really keen, the Wiltshire library network has a copy of the famous “Green Building Bible (2nd Edition)”, which can be reserved. Note that this book is now in it’s 4thedition. Wiltshire Council Virtual Library

Traditional Buildings

If you’re lucky enough to live in a lovely old house, some energy efficiency measures may be trickier due to building materials, conservation and planning issues. But don’t despair! There’s still plenty that can be achieved.

A collaboration between Bath Preservation Trust and Centre for Sustainable Energy produced this great report: Warmer Bath

English Heritage has produced a series of detailed guides on energy saving measures for older buildings.

Energy Assessment and Management

If you’re planning significant energy efficiency retrofit, a trained Energy Advisor could provide valuable and money saving input by identifying the most beneficial actions to take. A basic home Energy Performance Certificate style assessment starts at around £60, prioritising a hierarchy of energy saving measures. There are several energy advisors based in the Bradford on Avon community area.

Engaging an Installer

Ideally, your installer will be accredited with a competent person scheme relevant for their trade, or members of a trade association. Accreditation may be necessary to meet Building Control requirements in some instances, or to benefit from subsidy schemes. Small local independent enterprises will likely exist on good reputation and customer recommendations, and may not have membership of (often costly) trade bodies or quality mark schemes.

The government’s Green Deal initiative which went live in autumn 2012, requires installers and advisors working under Green Deal funded projects to be accredited with the scheme. 

If considering more adventurous eco-refurbishment, you may find professional designers and developers registered with:


It’s prudent to get more than one quote and ask installers for references or to visit recent projects; ask for personal recommendations from those you know and trust. A further check can be made on the following web-sites, though smaller local traders may not be listed:

  • Companies registered with government endorsed standards may be listed onTrustMark
  • If you’re a Which? subscriber, you can use the Which?Local scheme


There’s tonnes of stuff out there on home retrofit, this is a selection:
