Rule: If you move, Sky requires notification and will tell you if the new address can keep the same services. If the address cannot receive the service, Sky will allow cancellation. Required proof: tenancy agreement, completion statement or signed new address evidence. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
Rule: If Sky increases the price of the Boost add-on or the bundled service and you do not accept the change, you can cancel. Required proof: written notice of price increase from Sky or screenshot/email showing the change in terms. Applicable law: Consumer Rights Act 2015 and the Consumer Contracts Regulations 2013.
Rule: In the event of the account holder's death, Sky allows cancellation; the estate or surviving household must provide proof. Required proof: death certificate and proof of authority to act for the estate. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
Rule: If Sky Broadband Boost is not delivered with reasonable care and skill, or the promised 3Mb/s guarantee in every room is not met, you can complain and request repair or cancellation. Required proof: speed test results, engineer visit reports, dated correspondence with Sky. Applicable law: Consumer Rights Act 2015 (services performed with reasonable care and skill).
Rule: At the end of the Boost minimum contract (18 months) you can end the add-on without early termination charges. Required proof: Sky account showing contract end date. Applicable law: Contract terms governed by Sky contract and Consumer Rights rules.
Rule: For contracts concluded online or off-premises, consumers have a 14-day right to cancel under the Consumer Contracts Regulations 2013. If the service started during the 14-day cooling-off period, Sky will refund payments received but charge proportionately for services provided up to cancellation and for any installation costs. Required proof: cancellation within 14 days, returned equipment or proof of return. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
What to ask for: When you call Sky to cancel the Boost add-on, ask for retention offers such as temporary price reduction, waiving of the nightly or weekend engineer fees, or a free trial period for Sky WiFi Max. Research shows Sky may offer the Boost for free or at a discounted rate when renegotiating a package. If you want to keep broadband but not Boost, ask to downgrade the add-on or to include equivalent coverage in a re-contracted bundle.
Current Boost price: £5 per month. Annual calculation: 12 x £5 = £60 per year. If you cancel Boost you save £60 per year.
Cheapest competitor from research: Hyperoptic at £17 per month equals 12 x £17 = £204 per year. Other competitor prices: Vodafone £24 per month (£288 per year), GoFibre £22.50 per month (£270 per year), EE £26.99 per month (£323.88 per year), NOW Broadband £23 per month (£276 per year). If your aim is to remove the Boost add-on only, cancelling saves £60 per year. If you are switching provider entirely compare full-bundle costs: Hyperoptic £204 per year is the lowest full-provider price in our competitor list.
Relevant law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 - 14-day cooling-off right for online or off-premises contracts. Consumer Rights Act 2015 - services must be performed with reasonable care and skill and unfair contract terms are not binding.
The sector regulator is Ofcom. The Competition and Markets Authority (CMA) scrutinises problematic auto-renewal and hard-to-cancel subscription practices. If Sky refuses lawful cancellation or applies disproportionate penalties, you can escalate the complaint.
Step 1: Complain in writing to Sky with supporting evidence. Step 2: If unresolved, contact Citizens Advice for guidance and then the Communications Ombudsman. For qualifying card payments consider Section 75 or chargeback via your card issuer. Use the Consumer Rights Act 2015 and the Consumer Contracts Regulations 2013 as the legal basis when you complain.
After cancellation, expect a final bill showing any remaining monthly charges or early termination charges if applicable. If you cancelled during the 14-day cooling-off period and returned equipment promptly, Sky must refund within 14 days after receiving the equipment or proof of return.
If you received discounted equipment on condition of the contract and keep it after cancellation during the cooling-off period, you must pay the difference between the discounted price and the full standard price. You are responsible for returning the router and boosters; keep proof of postage.
If you wish to add Boost again after cancellation you will be subject to Sky's prevailing prices and contract terms. If you cancelled because of moving address, you can ask Sky to transfer services to the new address if technically possible.
Use this checklist to make sure the cancellation is completed and you keep proof.
