A Nisa shop owner thought his bills were fixed. He was quietly racking up arrears.

A Welsh independent retailer renovated his Nisa Local store and upgraded the meter — without realising his fixed-rate contract didn't actually cover his real usage. Months later, the supplier presented him with a sizeable bill of arrears. Here's how the partner network sorted it.

The business

HRQ Brothers Ltd operates a Nisa Local convenience store on Ystrad Road in Pentre, Mid Glamorgan. Owner Qais Aziz acquired the store in January 2021 — his first venture into independent retail.

Like many first-time convenience retailers, Qais inherited the previous owner's energy supplier and tariff. He renovated the store, upgraded the electricity meter, and got on with the business of running it. Energy felt like a fixed cost — same money out every month, nothing to think about.

The problem

Except it wasn't fixed. Qais was on a fixed tariff, not a fixed-bill contract. Two very different things — and the difference can run into thousands.

A fixed tariff means your unit rate is locked. It doesn't mean your monthly bill is locked. If your actual usage is higher than the supplier's monthly direct debit estimate, you build up arrears. Most operators don't realise this is happening because nothing changes on their statement — until the supplier reconciles and presents the bill.

In Qais's case, the meter upgrade and the busy convenience store created fluctuating usage that didn't match the supplier's flat-rate direct debit. Months passed. The same money came out of his account. The arrears quietly grew.

"Perhaps I took my eye off the ball a bit, in terms of what I was using, because the same money was coming out of my account each month — I was on a fixed tariff. I didn't realise I was in arrears. My usage was fluctuating over the months. I owed them a significant sum of money." — Qais Aziz, HRQ Brothers Ltd

The solution

Nisa is the partner network's preferred energy partner — meaning Nisa retailers can ring up and get help directly. Qais's Nisa representative referred him in.

The consultant on the case, Mark Ludford, did three things:

"Mark explained, in the simplest of ways, and helped me to understand my situation. He went above and beyond to put this plan into place and put me first, not the needs of his business. What more could I have asked for? I'm already talking to the team about my next contract." — Qais Aziz, HRQ Brothers Ltd

What this means for your restaurant or shop

If you run a restaurant, takeaway, café, convenience store, or any small retail unit — the most common trap is exactly what happened here. Fixed tariff ≠ fixed bill. Stable direct debits ≠ accurate billing. The only way to know whether you're quietly accumulating arrears or overpaying for kWh you don't use is to have someone look at the actual numbers.
