Energy Bills: Are you paying the correct Maximum Resale Price (MRP)?

Hi everyone. With the cost of living still biting, I think it’s worth reminding everyone about the rules regarding utilities. If you pay your site owner directly for your electricity or gas (rather than having your own direct contract with an energy supplier), they are legally bound by Ofgem's Maximum Resale Price (MRP) rules.

By law, site owners cannot make a profit on reselling energy to residents—they can only charge you exactly what they pay the supplier, plus their share of the standing charge. Has anyone ever requested to see their site owner's original utility invoices to check the rates are being passed on fairly? Also, don't forget that the Park Homes Warm Home Discount scheme usually reopens in September, so keep an eye out if you need to apply for the £150 rebate!

We are lucky we get to choose our own gas and electricity supplier, so shopping around ensures we get the best deals. I didn't realise a lot of parks bill the home owner. I looked it up and here's what I found.

Energy (Gas & Electricity)Regulated in Great Britain by Ofgem under the Gas Act and Electricity Act, the MRP ensures that landlords and site owners (e.g., park home pitch owners, HMO managers) cannot profit from reselling utilities.

The Cap:
You cannot be charged more per kilowatt-hour (kWh) than the reseller paid their own supplier.

Standing Charges:
These must be split fairly amongst the consumers sharing the supply.

No Profit Margin:
Resellers are strictly prohibited from adding markups or surcharges on the actual energy usage.Official Guidelines: You can review your rights and responsibilities in the Ofgem Alternative Homes Energy Guidance or the Ofgem MRP Direction. Hopes this helps.

Not sure about the warm homes discount scheme though?

What is the Warm Home Discount?
The Amount: A one-off £150 rebate on your electricity bill.

How it’s paid: It is applied as a credit to your electricity account (or, if you are a prepayment customer, sometimes as a top-up voucher or credit to your meter).

Timing: The scheme typically runs from October to March each year.

Who is eligible?
Eligibility is generally based on being on a low income or receiving certain means-tested benefits (like Universal Credit, Pension Credit, or Housing Benefit).

England & Wales: Most eligible people receive this automatically through data-matching between the government and energy suppliers. You usually don't need to apply, though you may receive a letter confirming your eligibility.

Scotland: The rules are slightly different. While the "Core Group" (pensioners on Guarantee Credit) get it automatically, low-income households in the "Broader Group" often need to apply directly to their supplier.

Important Note for Park Home Residents
If a park home resident does not have a direct contract with an electricity supplier (e.g., they pay for electricity via their site pitch fees or directly to the site owner), they are still eligible!

There is a dedicated "Industry Initiative" specifically for park home residents in this situation. They can apply for the "Park Home WHD," and if successful, they receive the same £150 payment.

If you are in England or Wales, you should keep an eye on your post between October and January for a letter from the government. If they haven't heard anything by January and think they qualify, they should call the official WHD helpline.

Disclaimer: the scheme for 2025/2026 has ended (it closed on 31 March 2026). The new scheme for 2026/2027 is expected to begin in autumn 2026.
