The flight itself
Nonstop flights from Lagos to London (Heathrow) typically take around 6h 30m to 7h, and exact times vary by aircraft, routing, and conditions. Nonstop LOS–LHR service is operated by British Airways and Virgin Atlantic. One-stop connecting options are also available, often via a European or Middle East hub — nonstop is usually fastest, while connecting itineraries can sometimes be cheaper.

What you need to enter the UK depends on your nationality
This is the part travellers most often get wrong. The permission you need is determined by the passport you hold, not by the airport you fly from. Two people on the same Lagos to London flight can need completely different documents.
There are broadly two paths: a visa, or an Electronic Travel Authorisation (ETA).
If you hold a Nigerian passport: you need a visa
Nigeria appears on the UK's visa national list — the list of nationalities that require entry clearance before travelling to the UK. It is entry 78 in Immigration Rules Appendix Visitor: Visa national list.
Nigerian citizens travelling for tourism, business, or a short course therefore need a Standard Visitor visa, not an ETA. According to GOV.UK's Standard Visitor guidance:
- It costs £135 for up to 6 months.
- You can usually stay in the UK for up to 6 months.
- The earliest you can apply is 3 months before you travel.
You must apply online before you travel to the UK, and at your visa application centre appointment you must prove your identity with your passport or travel document and have your fingerprints and a photo (biometric information) taken. After applying online, proving your identity and providing your documents, you'll usually get a decision within 3 weeks.
Because the earliest you can apply is 3 months out and a decision usually takes about 3 weeks, the application window is genuinely narrow. Plan the visa before you commit to non-refundable fares.
If you do not need a visa: you likely need an ETA
Travellers who don't need a visa for a short stay generally need an ETA instead. GOV.UK states that "Most visitors need an ETA or a visa. What you need depends on: your nationality [and] why you're coming to the UK", and that an ETA costs £20 and lets you travel to the UK for up to 6 months.
The Home Office ETA factsheet adds that an ETA "permits multiple journeys to the UK for stays of up to six months at a time over two years or until the holder's passport expires – whichever is sooner."
Whether your nationality needs an ETA or a visa depends on the passport you hold. Rather than reproduce a list here that could go out of date, check the official tool: check if you need a UK visa.
If you hold a British or Irish passport: you need neither
You do not need an ETA if you're a British or Irish citizen, or if you already have a UK visa. Dual citizens holding British or Irish citizenship cannot get an ETA and should travel on a valid British or Irish passport to prove their status.
Practical notes for this route
Because Lagos to London mixes Nigerian citizens, UK/Irish citizens returning home, and third-country nationals, one household can easily need three different documents for the same booking. Check each traveller individually, including children — the GOV.UK checker answers it per nationality.
Sort your permission before you commit to non-refundable fares. For Nigerian passport holders in particular, the visa window is narrow: the earliest you can apply is 3 months before travel and a decision usually takes about 3 weeks.
