Current government legislation allows us to charge lower rate VAT on our draught reduction services. Combined with the energy savings over the years that draught free windows can provide (see the Facts & Figures below) this can be a cost-effective investment.

How do we install a draught reduction system? Energy Saving Facts & Figures

Historic England Historic England suggest that servicing a window and applying a draught reduction system will reduce draughts by as much as 80% to 85%.

To quantify this we asked the Energy Saving Trust Energy Saving Trust ( what this equated to in terms of cash savings and CO2 emissions. They provided the following response:
"The average financial benefit from draught proofing all the single-glazed sash windows in a typical house is £45 per year. This equates to around 630 kWh and 120 kg of CO2 saved over the course of a year."
– Energy Saving Trust, 2022. - subject to increase with the September 2022 price cap change.

In terms of today's fuel prices, a 630 kWh energy saving amounts to around £97 per year off your electricity bill, or £23 per year off your gas bill (with dual-fuel savings somewhere in-between.)

Calculations based on the average unit-price per kWh for electricity and gas (inc. VAT) in the South West of England. According to Government domestic energy price statistics for 2017.

Historic England also suggest that a close fitting set of blinds, thick lined curtains and shutters will further reduce heat loss by as much as 30% through each window.
