Homeowner to save £1100 a year and emit 4 tonnes less of CO2
Services Used
Retrofit Assessment, Whole House Plan
The Challenge
The noticeable increase in the cost of energy meant that this homeowner was looking to reduce energy costs, make their house more comfortable and lower their carbon dioxide emissions.
They also wanted to enhance the value of their two-storey detached house by improving its EPC rating and its external appearance.
The Solution
After discovering the British Standard PAS2035 (the standard defining how retrofit projects should be managed and carried out), the client searched online for a ‘retrofit assessor’ and found Energy Lock among a list of local providers.
We carried out a retrofit assessment and whole house plan for the two-storey, 1930s-1940s detached house examining defects and the current level of ventilation. We also estimated the property’s current annual energy performance. From this, we produced a list of recommended home improvements or measures that could significantly reduce the homeowner’s energy use, costs and carbon dioxide emissions. These were phased to allow the benefits of the previous measures to take effect.
The measures we recommended were expected to:
-
Save the client over £1000 a year in energy bills.
-
Raise their EPC rating by two bands.
-
Reduce their carbon dioxide emissions by 4 tonnes a year (equivalent to that absorbed by 182 mature trees*).
*A mature tree absorbs 22kg of carbon dioxide a year. Calculation based on: https://www.eea.europa.eu/articles/forests-health-and-climate-change/key-facts/trees-help-tackle-climate-change
The Outcome
The homeowner received a thorough breakdown of the assessment and a detailed Whole House Plan which was made available to their architectural designer. The homeowner identified which improvements should be completed first and knew how much they could save over the phased timeline. The client felt confident to start with the approved works and to start receiving bids from construction teams.
