The Wi-Fi guarantee reality check
BT: what's actually guaranteed?
The short answer
BT aims to give a usable Wi-Fi connection in every room of the main home using the Smart Hub 2 and up to three Wi-Fi discs. If it cannot, the published remedy is generally a one-off £100 bill credit.
Well-established support and engineers, but the promise is about coverage and the final answer is money.

BT Complete Wi-Fi
What the advert says: "A reliable Wi-Fi connection in every room, guaranteed."
BT aims to give a usable Wi-Fi connection in every room of the main home using the Smart Hub 2 and up to three Wi-Fi discs. If it cannot, the published remedy is generally a one-off £100 bill credit.
| Minimum guaranteed Wi-Fi speed | 10 Mbps — BT describes a reliable connection rather than your package speed; the working figure is around 10 Mbps in the room. |
|---|---|
| Where it applies | Rooms in the main dwelling |
| Where it doesn't | Gardens, sheds, garages and outbuildings |
| Equipment you can receive | Smart Hub 2 plus Wi-Fi discs |
| Maximum extra Wi-Fi boxes | 3 |
| Engineer visit | Yes |
| What happens when it fails | Sends kit first, then pays out if it still fails |
| Compensation | One-off £100 bill credit (one-off) |
| Broadband faults covered | No — handled separately |
| Your own router or extenders allowed | No |
| Must you run their diagnostics first | Yes |
| Cost | Included with Halo-style plans, an add-on with others |
| Minimum term | Follows the broadband contract term |
| Cancellation | Add-on can normally be removed under the plan terms |
| Last verified | 9 September 2026 |
What you must do first
- • Work through BT's troubleshooting
- • Accept and place the discs as advised
What's excluded
- • Broadband faults are handled separately
- • Gardens and outbuildings
- • Setups using your own routers or extenders
- • Situations where the discs cannot be placed as advised
If it still doesn't work
Once three discs have been tried, the published route is the £100 credit. That is money rather than a further technical fix, so the coverage problem can remain.
The WiFiXpert view
A coverage guarantee with a hardware-first remedy. It is a reasonable safety net, but £100 is compensation, not a repair, and BT does not publish continuous device-level monitoring of your Wi-Fi.
Guarantee usefulness: 50/100
Limited: the threshold is low or the remedy is mainly money.
| What we looked at | Points | Why |
|---|---|---|
| How much speed is promised | 10/40 | 10 Mbps is enough for a single video call, not for a busy household. |
| What happens when it fails | 15/25 | Sends kit first, then pays out if it still fails. |
| Will somebody come out | 10/10 | An in-home visit is part of the published process. |
| How much extra kit you can get | 8/10 | Up to 3 extra Wi-Fi boxes. |
| How much is carved out | 2/10 | 4 published exclusions, including broadband faults on almost every provider. |
| How much you have to do first | 2/5 | You must complete their own testing before the promise applies. |
| How clearly it is published | 3/5 | Our confidence in the published detail is moderate. |

What to do about it
A guarantee compensates you if a threshold cannot be met. Managed Wi-Fi is intended to help identify and resolve the underlying problem. Before you claim either, it is worth finding out what is actually wrong.
