Our approach to affiliate links
Backup Power Calculator UK is an independent information and comparison website. Some links to products, retailers or services may be affiliate links. If you follow an affiliate link and make a qualifying purchase, Backup Power Calculator UK may receive a commission from the retailer or affiliate network. This does not increase the price you pay.
Calculator results come first
Affiliate relationships do not determine the result produced by our backup-power calculator. Calculator outputs are based on the information entered, the assumptions explained by the tool and the technical requirements used in the calculation. Where we show product-fit suggestions, the aim is to match those requirements rather than to favour a product because it pays a commission.
Editorial independence
Retailers, manufacturers and affiliate networks do not have the right to determine our editorial conclusions, calculator methodology or technical guidance. Commercial relationships may affect whether a link can earn commission, but they should not change the underlying assessment of what capacity, output or type of equipment is appropriate.
How we assess products
We do not claim to have personally bought, used or tested a product unless we explicitly say that we have. Product discussions and comparisons may rely on manufacturer specifications, manuals, technical documentation, retailer information and other published sources. Specifications, firmware, compatibility, prices and availability can change, so important details should be checked with the manufacturer or retailer before purchase.
Current affiliate relationships
Affiliate network(s): Awin.
Our affiliate relationships may change over time as retailers or networks are added or removed.
How affiliate links are identified
Where a page contains monetised product recommendations, we aim to provide a clear affiliate disclosure in or near the relevant content. This page explains the arrangement in more detail; it is not intended to hide or replace a disclosure where readers are making a purchasing decision.
Third-party purchases
Unless we expressly state otherwise, products linked from this website are sold by third-party retailers, not by Backup Power Calculator UK. The retailer is responsible for the transaction and its applicable prices, delivery, returns, warranties, customer service, privacy practices and sales terms.
Why we use affiliate links
Affiliate income can help meet the cost of hosting, maintaining and developing Backup Power Calculator UK, including the calculator and the independent guides published around it. You are not required to use an affiliate link to use the calculator or read the site.
