To any of you guys who use electric hose reels.
Which ones are the best value for money...?
Secondly I run my pump from a split relay on a 110ah leisure battery so I never need to recharge it.
Do you think I would be able to run an electric reel from that battery aswell on my split relay...??

Number 23's right as he has a setup in his van.
PowerUp state that their motor draws 275watts. It also says that its 12/24v. At 12v that is 23 amps. Let's round that up to 25 amps. (I can't imagine that figure is 275w at 24v.)
That's the equivalent of 5 Shurflo pumps running at the same time. Battery usage is going to depend how many times a day you reel your hose in, and how much hose you use (time taken to reel hose in.)
So the mathematical theory:
Lets say you do 15 houses a day and you reel out 50m of hose on average each time. Lets also say that it takes you a minute to wind 50 meters of hose in. (PowerUp say that it will reel in 100m in just over 30 secs but that will be a straight hose running at full speed.) You are going to use about 8 - 10 amps of your battery capacity each day. If you are considering a roller system to exit the hose through the floor then you may have to add a bit more power consumption due to resistance you may experience with the rollers.
Some leisure batteries do provide a CCA specification which means that they should be able to cope with current draw like that. (Most leisure batteries are used in the caravan leisure industry and could be used to power electric motor movers used to maneuver the caravan into position. But once on site most have electric hookups so will automatically recharge the battery.)
I wouldn't count on the SCR being able to cope with the added power drain. So I would expect you would have to supplementary bench charge your leisure battery . You are heading in Webasto diesel heater territory power consumption wise and many users have experienced flat batteries due to the additional power consumption of the heater.
Under idea conditions you should add a separate battery to power your electric reel, especially if you are thinking of 2. If you are doing enough mileage to keep the leisure battery charged then I would possibly consider running the electric reel from the van's battery if its big enough, but that would be a desperate 2nd option.
Lets see if the theory works out in practice in every day experience by users.
