Quote, switch and track any meter in the market.
Three products — domestic switching, non-domestic switching and non-commodity cost — all served by one quote engine, plus a registration tracker that follows every switch to go-live.
Domestic, non-domestic and non-commodity cost
Three products, one quote engine underneath all of them — plus a registration tracker that follows every switch after it is submitted.
Domestic switching
Household electricity and gas. Address-first, meter-matched, and priced on the home's real consumption rather than a typical-use assumption.
Non-domestic switching
Micro-business to half-hourly portfolio. Every contract structure the business market uses, with non-commodity charges modelled per profile class.
Non-commodity cost
The network, environmental and regulatory charges that make up more than half a business bill — calculated the way suppliers calculate them, for every profile class.
Four things most comparison engines can't do
Single rate, Economy 7, time of use, passthrough and full flex contracts — all priced by the same engine, so a household special and a business flex deal can be compared on the same basis.
The quote engine settles each of the 48 daily periods against the customer's own load shape. Most engines flatten time-of-use tariffs to an average and get the ranking wrong.
Switches are submitted into supplier systems directly — not passed on as a lead — with contract status returned. Coverage spans the entire live GB market, domestic and non-domestic.
The network, environmental and regulatory charges suppliers use to build their own customer bills, reproduced for every profile class — so the quoted price is the price that lands.
Domestic switching
A household journey that starts with an address, not a form. We find the meters, pull the consumption where consent allows, and quote against a real usage shape instead of an Ofgem typical-use assumption.
The customer types their address. We match the property and find the registered electricity and gas meters behind it.
Half-hourly or profiled usage retrieved with consent — or modelled from the property where no data exists yet.
Every available tariff costed against that usage shape, including time-of-use rates settled period by period.
The chosen deal goes straight into the supplier's systems through a direct integration.
Contract status flows back so the customer always knows where the switch is.
Day, night and evening/weekend registers priced against the meter's own register splits.
Rates that change by period, day and season — costed across all 48 settlement periods.
Commodity fixed, non-commodity charges passed through at cost and modelled per profile class.
Volume purchased in tranches against the wholesale curve, with risk and fee structures represented.
Non-domestic switching
From a single micro-business meter to a half-hourly portfolio on a flex contract. Non-domestic pricing is where the market gets hard — multiple meters, profile classes, bespoke uplifts and non-commodity charges that swamp the unit rate. All of it is modelled, not estimated.
Non-commodity cost calculator
More than half a business bill is not the energy. Network, environmental and regulatory charges are calculated for every profile class — using the same methodology suppliers use to bill their own customers, not a flat pence-per-kWh adder.
The tariff comparison engine
The quote engine behind all three products. It prices every structure in the market — single rate, Economy 7, time of use, passthrough and flex — against the same half-hourly consumption shape, so the ranking is genuinely like-for-like.
Rank a time-of-use tariff on annual volume alone and you get the wrong answer. We settle every period against the customer's own load shape.
Each of the 48 periods is priced against the customer's own consumption for that period — not a daily average.
Where metered data is thin, consumption is modelled from the property and profile class so time-of-use tariffs still rank correctly.
Commodity, standing charge, network, environmental and regulatory charges assembled into one comparable annual figure.
Flex and passthrough contracts modelled against traded curve positions rather than a single headline rate.
Rates that vary by season, weekday and weekend are represented exactly as the supplier defines them.
Quote a whole portfolio in one run and roll the results up by site, region or legal entity.
Every quote breaks down into its components, so a broker can defend the number to a customer.
Consume the engine through the Perse APIs, or use the hosted journeys — the same pricing either way.
Biggest panel of operational suppliers
Not a lead-generation handoff. The switch is submitted directly into the supplier's own systems, with contract status flowing back — so you can tell a customer where their switch actually is.
Coverage is maintained across the whole live market, domestic and non-domestic, as suppliers enter and leave it.
Contracts go into supplier systems through maintained integrations — no manual rekeying, no lead handoff.
Objections, cooling-off, registration and go-live all flow back into the journey.
ElectraLink and RECCo integrations return meter and consumption data at the point of quote.
Deals not on public comparison panels, including time-of-use products.
Registration tracker
A switch does not end when it is submitted. The tracker follows every registration through its life — in progress, cancelled or completed — with the expected go-live date attached, so nobody has to chase a supplier to find out where a contract is.
For third-party intermediaries that turns switch status into a forecast: which contracts will go live and when, what commission they represent, and which cancellations will come back as clawbacks.
