Yes, the Aisin TKT-021 is a good timing belt kit for the 2UZ.

Buying from Amazon/eBay is a gamble. You may not get genuine parts. I would suggest sourcing the Aisin TKT-021 kit from a reputable shop/distributor.

Thank you I can not find a reputable supplier in the uk that sells everything as a whole

This kit is coming from the US apparently

I will compare images of the parts to ensure the labels and branding prints are there. There’s thousands of good reviews but there are a few really bad ones too of arriving with wrong parts and cracks!

Toyota tell me no need to replace the water pump as it’s only 70k miles. Is this wise coming from a dealership?

Very inconsistent information and availability unless I pay £1500 for Toyota to do it

But then again Aisin £199 from Amazon also seems unwise the more I think about it

Would the engine be a write off it the timing belt snapped down the line?

The conundrum with replacing the water pump and fan bracket while doing the timing belt has to do with labor. Replacing them on their own is probably 80% of the labor to do a timing belt, but zero extra labor if done with the timing belt. In my mind it’s worth replacing them and knowing it’s nearly certain you won’t have to worry about it for another 90k miles.
 
Buy it from a reputable auto focused store. Amazon sells knock-offs sometimes. You never now where it comes from. And for a critical component like this, you don't want to skimp.

I would also change your Serpentine belt if not done already, it's not that expensive more. You're already in there you might as well.

You need to make sure you have the FIPG gasket compound if you do this job yourself. Like this: https://www.amazon.com/AISIN-AB1207B1-Black-Gasket-Sealant/dp/B01MUFWSBH

Check the model year of your truck. If you have a VVTI engine (the later two years of the 100-series) then you can't replace the cam seals unless you take out the whole valve cover and camshaft remove. It's a huge job. For older models you can replace the cam seal from the front after taking the pulleys off.

You can also consider replacing Crank seal.

I didn't replace the seals on mine as didn't look like it was leaking.

On my car, the fan bracket, fan clutch was really bad shape. I had to replace it. Also my serpentine belt idler pulley, tensioner on the serpentine belt, was in bad shape so I replaced those. Since I was already taking everything apart I just replaced all those too, it got expensive after replacing more stuff.

If you replace the timing belt, there are some electronic connector clips you have to remove. They get brittle with age and may break, then you need to buy a new connector. Same with the hoses, there are some you have to remove and some hoses may be in real bad shape so be careful, if you break them you need replace the hose. Make sure your car has original clamps on the hoses, if not buy new ones they're cheap, don't use worm clamps as they damage the hoses.
 
just a suggestion, change the heater "T"s also when doing the timing belt
 
Will do this yes! Are there metal ones available?

Some argue that it's best to just stick with plastic OEM and do them every 8-10 years.
