This page covers benefits of Retrofit and the PHribbon software for:
– Home Owners
– Councils, Housing Associations and Landlords
– Builders, Surveyors and Architects


For Home Owners

Thinking of having a new kitchen or bathroom? Why not improve the warmth of the room as well, it’s a unique opportunity. Here are some of the things a retrofit can do for you:

  • warmer home with more even temperature
  • eliminate mould (a cause of childhood asthma)
  • improve the style and appearance of the building
  • give you healthier warm fresh air, removing stale air, bacteria and mites, solvents (VOCs) from paints and materials and the moisture that causes mould. Best done with an MVHR, Mechanical Ventilation and Heat Recovery ventilation
  • cost effective – repairs may be needed anyway, improving warmth doesn’t cost much extra
  • cost effective – protect yourself from future energy price rises
  • cost effective – retrofits pay for themselves over their lifetime
  • reduce fossil fuel impact on the environment
  • reduce noise, triple glazing reduces road, train or aircraft noise


For Councils, Housing Associations and Landlords

Tennancy costs are used in our Retrofit Cost-Benefit service for Landlords and Housing Associations because the economics is slightly different. You’ll already be aware of the Minimum Energy Efficiency Standard, MEES which requires a minimum SAP rating of E for new properties this year, 2018 and existing properties by 2020. There are strong reasons to retrofit to a higher standard than that. Quotes below are from the Sustainable Homes report mentioned at the bottom of the page:

1) The government is considering increasing the MEES to SAP level D by 2025 and C by 2030. Works on a property are expensive and to apply them to all your stock requires a fair lead in time and therefore forward planning.

2) Rent arrears are a big problem. “The levels of rent arrears experienced by landlords ranged between 3.5% and 28%, with an average of 14%. There is a correlation between length of time in arrears and energy efficiency of homes…. Colder homes, especially those in band F, have on average two weeks more rent arrears than the rest of the bands each year.”

3) To reduce turnover* of your tenants. Energy efficient houses are in high demand meaning the amount of void time (the time a property stands empty between lettings) Administration costs are considerable for voids. “Landlords with more energy efficient stock are spending less on refurbishing void homes, less on repairs and less on staff time to manage voids.”

4) To minimise maintenance problems* such as persistent mould. Dealing with repeat maintenance problems means many visits to site, costs add up.

5) Landlords and housing associations usually have a long term interest in the property. Retrofits over these timescales are much more economic and attractive and can be combined with ongoing maintenance schedules.

For Builders, Surveyors and Architects

External insulation and painting. Sometimes clients want to know the cost of a few options before they go ahead.

This can be time consuming and uneconomical for the builder, and after all this work there is no guarantee the client will go ahead. We can work with the client to find a solution they like from a series of options. Builders rates remain confidential and all the energy calculations and take offs are done by our software.

This saves you a great deal of time and also helps your clients get what they want.
