LPG service

Does anyone know where I can get a lpg service around Blackpool/Preston area. Been googling like mad just want to make sure it’s all good and works as it should. I can’t find anywhere that does do ypu have any ideas.

Update I have found a company in the north west that do LPG still. I’ve spoke to a lot of companies that don’t do it anymore so glad that I found one. They are in Bolton CRD performance if this of any use to anyone in the future. Cost of service is around 150 mark depending on system. They do a courtesy car as well which helps.
