With 60 per cent of homeowners unaware of what retrofit is, TrustMark, the only Government Endorsed Quality Scheme for works carried out around the home, has launched a guide to help explain and simplify what retrofitting your home means

In a recent YouGov survey amongst UK homeowners* carried out by TrustMark (1), 60 per cent of these homeowners were unaware of what retrofit means. From those who were aware of the term, over half (57%) had not seen, read or heard an explanation that could help them understand it but 53 per cent of all homeowners were interested in knowing more and would welcome an easy to understand guide.

Retrofit is the process of making changes to existing buildings so that energy consumption and emissions are reduced. With energy costs rising by over 50 per cent (2) and inflation running at over six per cent, (3) the increased pressure on household running costs makes improving energy efficiency in homes a higher priority. And whilst around half of homeowners (49%) are planning home improvements in the next year, nearly one fifth (19%) cited energy efficiency measures such as loft or wall insulation, double glazing or installing a new boiler as high on their list..

Simon Ayers, CEO TrustMark explains, “We are all aware of the need to make our homes greener and more energy efficient, not only to reduce our costs and carbon footprint but also make our homes warmer, healthier and more comfortable to live in. However, it’s not just a case of insulating everywhere possible and blocking up every space to prevent draughts. There’s a right way to go about it. Using a qualified and accredited Retrofit Professional who will take into account the property as a whole, how you and your family use your home as well as your budget will result in a bespoke plan for your property that can be implemented in stages to suit your timescales.  Engaging professional, skilled tradespeople working to the proper industry standards will help to ensure homeowners get the best outcome and value for their investment. But It can seem very complicated which is why we’ve produced our guide to help simplify the process.”

TrustMark’s guide covers energy efficiency tips and a simple explanation of Energy Performance Certificates as well as answering the whys and wherefores of the retrofit process, who can carry out the work, finding the right person and what to do if something goes wrong. It also provides a handy checklist of questions to ask tradespeople when getting quotes for work to be done.

When it comes to having work carried out at home, the top two things people look for in a tradesperson were “quality of work” and “trust” - not surprisingly – with 98% and 97% respectively citing these as their top requirements. Interestingly, using a well-known name scored bottom with less than half (46%) considering it important.

Finding the right tradesperson is also where TrustMark can help with their ‘find a trader’ facility via the website. TrustMark Registered Businesses must be validated by their Scheme Provider(s) and also commit to adhering to high standards of technical competence, customer service and trading practices. They are also required to provide warranties and minimum guarantees where applicable.
