Q: What type of upgrades am I looking at if I want to reduce energy consumption at home?

A: The most common upgrades includes loft insulation (270mm insulation put on the loft of standalone and semi-detached houses), cavity wall insulation, changing boiler, change old windows to new double/triple-glazed windows, energy efficient lighting and improved heat control system such as thermostat. Older homes may also do full solid wall insulation, in which case you can get a brand new facade. You can also invest in solar pv panels to reduce your energy consumption from the grid.

Q: How much would it cost if I want to improve insulation of my home?

A: The Energy Trust has a great overview of estimated cost for insulation. Briefly said, loft insulation can cost between £3-400 regardless of type of property. Cavity wall insulation for a house would cost around £700, while semi-detached house around £500. For a flat it would cost around £300.

Q: We are thinking about selling our home. Is it really true that we could get a higher price if we invest in energy efficiency measures?

A: Yes, it’s definitely true. The research done by the University of Cambridge for the UK government (Department of Energy and Climate Change) found a clear correlation between house price and energy performance rating when they surveyed more than 320,000 households in the UK. The correlation of increased sales price when energy rating is improved is also found in many other countries (credit to Dr Franz Fuerst):

EU data

  • Netherlands 2009: 10%, 5,5% and 2,5% premium for A, B, C rating respectively compared to D. 0,5%, 2,5% and 5% discount for ratings of E, F, G
  • Austria/Vienna 2013: 8% increase in sales price for each change in EPC rating
  • Belgium 2013: 3-5% increase for every increase in 100CPEB point
  • France (Marseilles, Lille) 2013: 4% increase per change in EPC rating
  • Ireland 2013: 2,8% increase per change in EPC rating
  • UK 2015: 5% increase for A/B and 1,8% increase for C compared to D. 0.7%, 0.9% and 6% discount for E, F and G respectively compared to D.
  • Wales 2016: 11.3% increase for A/B and 2.1% increase for C compared to D. 2.1%, 4.7% and 7.2% discount for E, F and G respectively compared to D.

Non-EU data

  • Australia 2006: 2% price increase for every 0,5 increase in EE rating on 0-5 scale
  • California 2012: 2% price increase in houses with green labels compared to without
  • Singapore 2010: Green Mark dwellings had 4-5% price increase compared to non-Green Mark dwellings

Q: How does it work if I want to use Polareco’s services?

A: That’s easy! Just send us an email (go to Contact us), and we’ll get back to you in no time. We will do an assessment of your property together with some of our great energy efficiency experts, and let you know what it would take to improve your energy rating by one or two bands (or more!). Say that you live in a flat in London, and your current EPC report is rated D. We will look at windows, walls, floor, heating system, energy systems, lighting, and then let you know what exactly what has to be done to increase your rating, how much it will cost, and how long it would take. We may suggest you change boiler, insert wall cavity insulation and change your lighting, at a cost of £4000. If you know that your flat has an estimated sales price of £400,000, you are looking at a increase in sales price of£8000-£40,000.

Q: Do I have to pay for the sighting of my property?

A: Yes, the service costs £300. This is because our home energy assessors have to get paid for the hours they spend getting to your house and collecting all the data, and then we also have to obtain quotes from different installers for you and put it together to a complete offer for you.

However, you get to pick the brain of an expert on basically any question you may have relating to home energy use, and you will get a offer of works with quotes from actual installers. Whether you decide to book with the installers we have vetted and hand picked, or you decide to use the quote to negotiate with other installers, the decision is yours. It is in any case a valuable document full of info!

Q: What about subsidies, can I be eligible for that?

A: Yes, you may be eligible for subsidies and government grants. It’s quite a jungle out there depending on what measures you will undertake and what your housing situation is, but if there is a grant that fits you, we will do what is in our power to ensure you get access to it.
