Which business energy suppliers serve London?

Most major UK business energy suppliers serve London, including British Gas, EDF Energy, E.ON Next, Octopus Energy, Shell Energy, ScottishPower, and others. Availability and tariffs vary by postcode and meter type.

How can I compare business energy quotes in London?

Have a recent bill ready and your MPAN/MPRN numbers. We’ll compare live prices from multiple suppliers based on your consumption, contract end date, and preferences (e.g., green energy), then present the best options and help you switch.

How long does a business energy switch take?

Most switches complete in 2–4 weeks. There’s no interruption to supply. We arrange the contract and supplier handover; you provide an opening meter reading on the go-live date.

Can you help with half-hourly, multi-site, or high-usage meters?

Yes. We handle half-hourly (HH) and non-half-hourly meters, multi-site portfolios, and high-usage profiles. We can also review kVA capacity and demand charges to identify savings.

Do you offer renewable or carbon-neutral tariffs?

We can source 100% renewable electricity and green gas options where available, and provide guidance on REGO-backed tariffs and carbon reporting to support your sustainability goals.

When should I lock in a new business energy contract?

Start 6–12 months before your current contract ends. Early pricing helps you avoid out-of-contract rates and lets you time the market if wholesale prices improve.

What information do you need for a quote?

Business name and address, postcode, MPAN/MPRN, current supplier, contract end date, latest kWh consumption or bill, and your preferences (fixed vs flexible, contract length, green energy).

Is there a fee for your service?

Our comparison and switching support is typically commission-funded by suppliers, so there’s no upfront fee for most businesses. We’ll confirm any charges transparently before you proceed.

Can you help if my business is new or has no usage history?

Yes. We can estimate usage based on your business type and premises size to obtain quotes and set up your first contract in London.

Tariffs from home energy suppliers in London

Understand your options before you switch.

Fixed-rate tariffs

Lock your unit rate and standing charge for a set term (e.g., 12 or 24 months). Great for budgeting. Some plans may include exit fees if you leave early.

Variable-rate tariffs

Prices can go up or down with market changes. Usually no exit fees. Suitable if you prefer flexibility or expect rates to fall.

Prepayment (Pay-As-You-Go)

Top up via key, card, or app. Helps manage spending. We’ll show competitive prepay tariffs and any available support for installing a smart prepay meter.

Economy 7/10

Cheaper night-time electricity and higher daytime rates. Works well with storage heaters or EV off-peak charging. Provide usage split for accurate quotes.

Smart meter installation in London homes

Smart meters for London homes

Many London suppliers offer smart meters with in-home displays so you can track usage in real time. Smart meters can support half-hourly data for more accurate bills and enable smart prepay or time-of-use tariffs.

No extra cost for a standard smart meter installation from most suppliers.
Keep your existing tariff or switch to a compatible smart tariff.
Prepay customers can top up online or via app once upgraded.

Check smart-ready tariffs

Green energy options in London

Want to reduce your carbon footprint? Choose tariffs backed by 100% renewable electricity and, in some cases, carbon-offset gas. We highlight fuel mix disclosures and any green certifications provided by each supplier.

100% renewable electricity tariffs available from multiple London suppliers.
Some plans include carbon-offset or biogas blends for gas.
Look for REGO-backed electricity and transparent environmental reporting.

Tip: cut usage without compromise

Use programmable thermostats; aim for 18–21°C.
Switch to LED bulbs and efficient appliances.
Insulate lofts and draught-proof windows and doors.
Use off-peak timers for EVs and washing machines (Economy 7).

Frequently asked questions

Answers to common queries about London energy suppliers and switching.

Will my energy be cut off during a switch?

No. Your gas and electricity continue as normal. The change happens in the background between suppliers.

How long does it take?

Most switches complete in 5–20 working days, depending on supplier processes and your cooling-off period.

Do I need a smart meter?

No, but smart meters provide accurate readings and unlock additional tariff types. You can switch with a standard meter, too.

What affects my London bill?

Usage, property efficiency, meter type, payment method (e.g., Direct Debit), and regional standing charges all contribute to your total cost.

Can renters switch suppliers?

Yes, if you pay the energy bill directly. Check your tenancy agreement for any clauses, and inform your landlord of changes.

What about prepayment meters?

We show competitive prepay tariffs and can help you explore switching to smart prepay or credit meters where eligible.
