How often is PowerGuardian's data updated?

Octopus tariff rates update daily. Other supplier information is dated when checked. Confirmed Ofgem caps and attributed forecasts show their source and check date.

Is PowerGuardian independent?

Yes. We're an independent UK energy information service. Some articles contain affiliate links, but our comparisons and analysis are not influenced by suppliers.

How can I save money on my energy bills?

Compare suppliers, avoid default variable tariffs, submit regular meter readings and use our calculators to find the biggest savings for your home.

What is the energy price cap?

Ofgem's price cap limits the maximum suppliers can charge per unit of energy and per day in standing charges on default variable tariffs, and it changes quarterly.

Should I fix my energy tariff?

Fixing protects you against price rises but you may miss out if prices fall. Use the confirmed cap, attributed forecasts and our 'should I fix?' guidance to assess your situation.
