For the last 2 hols we've used https://nwp-online.co.uk/ . We had to have a PCR to get into Mauritius and literally went to their doorstep picked up the test kits and did them there and then in the car park, we also picked up our day 2 tests at the same time. Used them before when we went to Portugal, very quick with the results and the fact with us being in Rugby there was no need to rely on the post.
We also used https://nwp-online.co.uk/ for our pre flight covid tests and the ones on our return for the Passenger locator form.
Results back within 24 hours. Like @greys4life we're in Rugby and the test centre is 15 minutes from us (Bitteswell).
Don't forget you now need an LFT test before leaving Tenerife and a PCR test before Day 2 after your arrival.
I would highly recommend Chronomics for the LFT, and have used Randox for the Day 2 PCRs. I don't know what Chronomics are charging for PCRs but they seem to work well, so may be an alternative to Randox. Your airline may have a discount code for a fiver off Randox (£43 instead of £48).
Just curious but do you take the swab sample yourself for the Lateral flow tests before flying?
If so, surely thats a virtually pointless excercise as I'm sure not many folks try too hard to get a good sample & then risk being stranded abroad at your own cost, potentially for weeks on end.........surely most will skip/fake it to ensure getting home & then just do a proper PCR when home?
Eurofins is a solid and reputable lab my company uses for finished goods & environmental testing etc. Won’t be the cheapest on the list, thing it’s £50 for the day 2 PCR home delivered.
Not sure about which covid tests you need to travel abroad. Some destinations require you to take a test before leaving the UK and can be expensive for families. Use MoneySavingExpert's tips to lower costs.

However, logistics are also likely to play a part and it’s worthwhile checking the procedures for getting the test back to where it needs to be. I was fortunate in that Randox has a drop-off in Leicester near where my sister lives.
