How our savings work

01

Pick a quick win

Every product explains what independent guidance says it could save, how that was worked out, and links to the source.

02

Install in minutes

No tradespeople, no tools beyond a screwdriver. Most upgrades take less time than making a cup of tea.

03

Check your own bills

Real savings depend on your home, your tariff and how you use each product. Where evidence can’t support a figure, we tell you.

Our Independent Research Promise

Honest savings figures, backed by evidence.

Money-saving claims are easy to exaggerate. We’d rather tell you what the evidence actually supports. Right now, 2 of our 9 products have an independent yearly savings estimate. For the rest, we explain what is known and why we don’t give a figure.

Checked against independent guidance

We compare every savings claim with published research and advice from reputable independent organisations, such as the Energy Saving Trust and Which?, where relevant to the product.

Every figure linked to its source

Each product page explains how the saving was worked out, what it depends on and links straight to the original guidance, with the date it was published.

No figure where the evidence runs out

If reliable evidence can’t establish a saving, we say so rather than guess. We don’t add savings together across products, because they can overlap.

About the figures

Energy Saving Trust figures are for Great Britain and use the Trust’s published price assumptions: electricity at 24.7p/kWh and gas at 6.5p/kWh, averaged across recent Ofgem price caps. Your saving will differ with your tariff, home and how you use each product.

The Energy Saving Trust, Which? and WRAP are independent organisations. They have not tested, approved or endorsed The Cost Savings Shop or any product we sell. We simply cite their published guidance.
