Eco-renovation for Builders

5th April, 9:00 am6th April, 4:00 pm

Essential skills for retrofitting energy efficiency improvements in homes

Also suitable for householders

Increased awareness and press coverage means there is a growing demand for eco-renovation measures from householders but a dearth of contractors in Greater Manchester to meet demand.

You may have experience of insulation installations or low carbon M&E works and want to extend your services to meet this demand. Or you may want to underpin practical knowledge with theory.

People Powered Retrofit* is running this subsidised, high quality, two-day training session for small-scale building firms, contractors and sole traders. The training is classroom-based, involving practical demonstrations.

Details: 5th and 6th April, 9am – 4pm each day. Lunch including, free on-street parking available nearby.

Who is it for: sole-traders, SME contractors and building firms

Prior knowledge: Some experience of installing energy efficiency is helpful but not necessary

What will be covered:

  • Key market opportunities in Greater Manchester

  • Housing stock retention

  • Climate change and the home

Establishing the base-line

  • Home audits and assessments: EPC and alternatives

Following the rules

  • Building regs: an introduction to Part L

  • …and aiming for better

Key principles

  • Detailing

  • Moisture: key risks


  • Examples of good and poor practice
