How to insulate your house is about making your home more comfortable to live in, thereby preventing the urge to ramp up the heating. It's therefore also about saving energy, and saving money and carbon — particularly important in present times. And having insulation installed will usually repay the investment many times over. Better, in that respect, than any form of renewable energy. 

But if you’re renovating a house how much are you likely to have to budget to insulate it well? And if your budget is restricted, should you invest in one thing above the other — for example, is insulating walls more important than insulating than the roof? Or should you strike a balance between insulating the whole house?

Tim is an expert in sustainable building methods and energy efficiency in residential homes and writes on the subject for magazines and national newspapers. He is the author of The Sustainable Building Bible, Simply Sustainable Homes and Anaerobic Digestion - Making Biogas - Making Energy: The Earthscan Expert Guide.

His interest in renewable energy and sustainability was first inspired by visits to the Royal Festival Hall heat pump and the Edmonton heat-from-waste projects. In 1979

this initial burst of enthusiasm lead to him trying (and failing) to build a biogas digester to convert pig manure into fuel, at a Kent oast-house, his first conversion project.

Moving in 2002 to a small-holding in South Wales, providing as it did access to a wider range of natural resources, fanned his enthusiasm for sustainability. He went on to install renewable technology at the property, including biomass boiler and wind turbine.

He formally ran energy efficiency consultancy WeatherWorks and was a speaker and expert at the Homebuilding & Renovating Shows across the country.
