Having researched all the ins and outs of refillable LPG tanks I decided to make a purchase from MTH Autogas. Last October on a trip return journey I drove to the Forest of Dean to the address of MTH Autogas and found that they had just closed down and ceased trading. Subsequently I trawled the internet and called many suppliers of bulk tanks and equipment without much success in finding a supplier willing to deliver the correct sized tank and ancillary equipment off the shelf, and be able to offer a similar service, by way of advice etc, as previously was available from Richard Cecil at MTH.
We had decided that all our problems would be answered by the fitting of a refillable bulk tank thus:-
A larger volume available
Cheaper costs of the LPG
Making the existing gas locker available for storage
Instant knowledge of exactly how much LPG is in the tank
No necessity of manhandling heavy expensive replacement cylinders
The ability to refill overseas
Cost likely to be reclaimed by savings during the lifetime of our van.
Via the internet I found a company in Caernarfon http://autogastanks.co.uk/
and posted on Mhf to see if anyone had any experience with them. I received not one reply in respect of that company so, albeit with some hesitation, contacted them. The result was very positive and the knowledge and assistance beyond reproach. FES (Farrow Engineering Services) Autogas is run by Nick Farrow who has an in depth knowledge of all things LPG, and, also a motor homer himself and a MHF member too.
FES do not offer a fitting service but carry massive stocks of tanks and equipment (supplying many manufacturers whom we all know very well) and are able to specify and supply everything needed for an installation down to every last fitting, hoses and accessories.
Surprisingly after the original disappointment regarding MTH I found a supplier with the knowledge and stock availability to supply everything to economically obtain all the equipment to enable a local skilled fitter to install a new bulk system.
I chose a 38 litre tank that comes with the fixing legs already welded to it thus obviating the need for a frame. This proved an advantage in fitting to the underside of our panel van. This tank, at 80% holds 30 litres, at the time of first filling "draught Calor gas" cost £0.62p / litre and bottled Calor cost £1.38 / litre (6kg rate). I have yet to explore the 10% VAT saving.

P.S. I have no affiliation or personal relation with the above company and am just sharing my own opinion and experience, hopefully, for the benefit of others.
