Booking in the middle of the week generally beats weekend departures, since demand for Friday and Sunday Nairobi flights runs higher across the board.
A handful of airlines cover this route. Kenya Airways runs direct find flights from London, and British Airways also flies the route directly out of London Heathrow. Brussels Airlines is a solid one-stop option if you're flexible on a connection, routing through Brussels rather than flying direct to Nairobi airport and one-stop fares can beat the price of a direct popular flight ticket to Nairobi depending on the week you're searching. It's worth comparing a direct flight against a one-stop before assuming direct is automatically pricier; sometimes it isn't.
Search London Gatwick and London Heathrow separately rather than assuming the fares match. Airlines don't always price a route the same out of each airport, and Heathrow tends to carry more of the direct options while Gatwick sometimes turns up a better one-stop fare.

If you're not booking yet, set up a price alert instead of checking manually. Flight with Kenya Airways on this route tend to move in small increments, then jump once a flight starts to fill.
