Can I switch business energy for several buildings at once?
Yes. Most suppliers will quote and switch several sites in one go, but each site has its own meter point and contract end date, so each switch is processed separately and may start on different days. Check every site's end date first.
Each site is switched separately
Every building has its own electricity meter point (an MPAN) and, if it has gas, its own gas meter point (an MPRN). A switch is really a transfer of one meter point to a new supplier. A portfolio deal simply bundles several of those transfers into a single quote and a single agreement.
So a "multi-site switch" usually means one negotiation, one set of contract terms, but several start dates.
Why the start dates can differ
If your sites were signed up at different times, their current fixed terms will end on different days. Under Ofgem's rules, a supplier can only block a business switch where your contract gives it the right to, and the commonest grounds are an unexpired fixed term or unpaid debt (Ofgem objections decision). Moving a site early can therefore mean termination fees or a blocked switch.
A sensible approach is to list every site, its supplier, its contract end date and its annual usage, then decide whether to wait or to move sites that are out of contract straight away. Sites on deemed or out-of-contract rates have no termination fee, so they are usually the first to move. See how to get off deemed or out-of-contract rates.
Joined-up or staggered?
| Approach | Good for | Watch out for |
|---|---|---|
| All sites on one aligned end date | One renewal diary, one contact, easier comparing | Switching early may trigger fees on some sites; you might lock in at a bad moment |
| Move sites as each contract ends | No early-exit fees | Several renewals a year, different terms per site |
| One supplier for gas and electricity at every site | Simpler admin | Not automatically cheaper; compare each fuel too |
What you will need
- The MPAN and MPRN for every site (they are on the bill; see how to find them).
- Annual usage per meter, not just a combined total.
- Each site's contract end date and any notice terms.
- Who is authorised to sign for the business. If a broker is involved they will want a letter of authority.
Microbusiness and small business protections depend on how your business measures against Ofgem's staff, turnover and annual usage tests, and a business can qualify for one fuel but not the other. How usage is counted across several sites is not spelled out in the guidance we checked, so ask each supplier in writing which rules it will apply to your sites.
Different premises, different set-ups
Sites differ in ways that affect the quote: one may have a half-hourly meter and another a standard one, and capacity charges can apply to larger supplies. For bigger portfolios, read our guide to multi-site and large business energy.
Next steps
- Build a one-page schedule of sites, meter numbers, usage and end dates.
- Ask for quotes both as a bundle and per site.
- Check each contract's principal terms before signing, including any broker fee.
