How this check works
Purchase price + replacement cost × replacement count + monthly subscription × 12 × years.
Assumptions & limits
The first consumable is included with the purchase. Replacements occur after each interval, excluding one due exactly at the end. Prices stay constant. Energy, repairs, delivery and resale are excluded.
Worked example
Illustrative user-entered prices: purchase £100, replacements £12 every 6 months, subscription £2 a month, over 3 years. The first consumable is included.
5 replacements cost £60.00; subscriptions cost £72.00. Total: £232.00, or £77.33 a year. These are example inputs, not product prices.
Before you decide
- Find the exact model’s current instructions and confirm the UK version.
- Check fitting, consumables, paid features and the maker’s support statement.
- Keep uncertain details on your checklist and check the returns policy before buying.
