I have been using Startron. If I go to my local chandler he may well have a different brand. Are they all the same stuff? Is it ok to mix them?

They're not all the same stuff, but it seems OK to mix them. I've mixed them several times when changing brands. Currently, I'm using Marine 16 which seems effective.

Premier, gosport marina sell their diesel with an additive already mixed.

I have seen suggestions that it's a good idea to use both the emulisfying type and the bugicidal type.

I've also used Marine 16 for several years now and seems to keep the diesel clean, I do use white road diesel. Very little evidence of contamination when filter changing.

I alternate between Fuel set as an emulsifier and Marine 16 as a bug killer.
I typed a while ago (think it was on the MB forum, simple diesel scrubbing) regarding a bug getting used to a treatment so it being a good idea to rotate different ones

Also had the same question as there is a tiny bottle of Spartron on the boat with a £21 price tag 
that says it treats one thousand litres. That is a lifetime for me with a small Beta engine... hope it preserves itself as well as the diesel!!

Did you mean the de-emulsifying type?
Marine 16 is a brand which covers deveral products, it would be helpful if people discriminated between DFC and Bug Killer:
Diesel Fuel Complete
Price From £10.16 incl VAT
Marine 16’s Diesel Fuel Complete is a multi-functional fuel treatment to maintain the quality of stored fuel, keep fuel systems clean and prevent the growth of Diesel Bug.
Diesel Fuel Complete Description
DFC – Diesel Fuel Complete is a multi functional fuel treatment for stored fuel. Using a blend of additives to give complete protection from the undesirable effects of modern Diesel. DFC Prevents degradation. Prevents the growth of diesel bug. Combats effects of using Ultra Low Sulphur Diesel (ULSD) and BioDiesel. Increases Cetane number for easier starting. Contains a lubricant. Contains a Detergent for cleaner easier starting, reduces fuel system and injector deposits to zero. Reduces emissions and improves fuel consumption. Suitable for all diesel engine types and all diesel fuels.
DFC also contains a demulsifier helping to drop water to the bottom of the tank where it can be easily removed from the drain or if no drain is fitted consider fitting a Diesel Dipper®. Water in Diesel must be removed and can cause serious damage to an engine.
Dose DFC at the rate of 100ml per 100 litres of fuel, overdosing will not harm your engine.
Diesel Bug Treatment
Price From £13.07 incl VAT
Marine 16 Diesel Bug Treatment (DBT) is a Biocide formulated specifically for preventing or eradicating the microbial contamination known collectively as Diesel Bug.
Diesel Bug Treatment Full Description
DBT – Diesel Bug Treatment is a broad spectrum biocide formulated to prevent or eradicate the microbial contamination of fuel from Yeast, Mould and Bacteria commonly known as Diesel Bug. A 100ml bottle is sufficient to prevent diesel bug growth in 2000 litres of fuel (50ppm). For serious contamination this should be increased to 100ml to 100 litres (1000ppm). Our diesel bug treatment disperses into both the water and fuel phases in your tank and will remain sufficiently active for over a year at both high and low temperatures. Marine 16’s Diesel Bug Treatment is the fuel treatment of choice for the RNLI, The Royal Marines, Sea Start and River Canal Rescue as well as being number 1 in the Practical Boat Owner magazine review.

I was thinking of the emulsifying sort (see E-ZOIL | Emulsification vs. Demulsification for the difference) but the general principle is the same: dealing with water in the fuel and also dealing with anything growing in the fuel.

I've been using Fuel Set for many years, road diesel for the last 15 or so. No problems - so far Fuel Set | Liquid Engineering UK Ltd

Fuel Set is popular with some boaters, but note that it doesn't specifically kill diesel bug.

Not sure what happens if we mix emulsifiers with demulsifiers.
I'm told people used to add alcohols to dissolve the water in the diesel?

It's a preventative rather than a cure, by dispersing or converting the water where bugs grow. As you say, it's not for use where there's an existing infestation.
