The air in your home, office or classroom generally becomes unhealthy after 2 hours of occupation if the windows are not opened. Our ventilation regulations that primarily rely on open windows were never fit for purpose. Poor quality air causes fatigue, poor concentration, the increased spread of colds and flu and in the long term is a contributory factor to many serious diseases.

An 80mm thick hot water cylinder insulation jacket costs around 15 and when placed over the existing cylinder insulation should save you at least 50 a year. You will save even more if you insulate the pipes between the boiler and the cylinder and any pipes around the cylinder. Try to ensure there are no gaps.
The average dwelling has total gaps & holes the size of 5 basketballs (an air leakage rate of around 12m/hr/m). Draught sealing your dwelling could seal up 2 basketballs sizes of gaps and save you 100 a year. A commercial property generally has 8 basketballs of gaps and holes or an air leakage rate of around 20m/hr/m.
Heat lost through junctions such as window sills & reveals, ceiling and floor perimeters can account for up to 25% of the heat loss of a building. The Building Regulations heavily penalise designs that have not used thermal modelling to measure heat loss from these junctions. For example the default Y- value in the SAP is 0.15w/mk.
We can issue an Energy Performance Certificate or an EPC for new and existing dwellings. Our EPC Prices start from 40. I have been a SAP Energy New Build Assessor since 2008 and have worked in various schemes involving over 250 dwellings including Code for Sustainable Homes Level 3 & 4 dwellings. What is an EPC?
What is BREEAM Domestic Refurbishment? BREEAM Domestic Refurbishment provides a design and assessment method for sustainable domestic refurbishment projects, helping to improve the sustainability and environmental performance of existing dwellings in a robust and cost effective way.
The scheme allows developers, designers and Green Deal advisors to demonstrate their environmental credentials promote better design and give confidence to their customers.It also helps planners, regulators and asset managers e.g. Registered Social Landlords to set standards for refurbishment, and provides a market-focused label for more sustainable and higher quality refurbishments.
