Usually they fall into the lowest band (A) but you should enquire of the seller.
When there is no mains gas, as is sometimes the case in rural areas, Liquefied Petroleum Gas (LPG) is the closest alternative. LPG is used for central heating, water heating and cooking. It can be stored in cylinders, in a tank (above or below ground) and delivered to a property via a pipeline.
No. The energy regulator, Ofgem, issued a Direction under the Utilities Act 2000 to ensure that: the maximum price at which mains gas or electricity can be resold is the same price as that paid for by the person who is reselling it. This is known as "pass through" and ensures that the park operator cannot sell at a premium.
Modern park homes are well insulated and have e.g. energy efficient boilers. Running costs in older homes can be reasonable too.
The scheme is open to permanent park home residents in England, Scotland or Wales. If successful, you will receive a one-off payment of £140 towards your electricity bill. You can apply for the WHD if you are resident on a park home site and pay for your electricity through your park, or as part of your pitch fees. It is administered by Charis Grants Ltd and it is designed to help vulnerable residents, primarily those of pensionable age/on benefits - apply as soon as possible.
