Six commitments we make to every client, whatever the size of the account.
You see every suitable quote
Not just the one we recommend. The options side by side, so you can check our advice for yourself.
Transparent pricing
We explain how we're paid and confirm it in writing before you sign. No hidden fees, no surprises.
A wide panel, not a favourite few
We contract with 17 major energy companies, who all bring different skills and pricing. In our experience, prices can vary by up to 28% between the highest and lowest quote, so we always go wide.
A personal service, start to finish
You'll have a direct line to a team that knows your account. No call centre, no handovers, no explaining your business twice.
We stay after you sign
We check your first bills, watch the market for you, and start your renewal months early, not a week before it lapses.
Somewhere to turn if things go wrong
If we can't resolve a complaint within 8 weeks, you can take it to Ombudsman Services: Energy, free of charge. Details are in our complaints procedure.
Four steps. We do the chasing.
Send us a bill
A recent bill and your contract end date is all we need to get started.
We tender the market
We approach suppliers across our panel and time the purchase to market conditions.
You choose, fully informed
Every suitable quote and rate, side by side, with our recommendation.
We switch you, and stay
We handle both suppliers, check your first bills and put your renewal in our diary.
You'll sign a simple Letter of Authority so we can speak to suppliers on your behalf. It doesn't commit you to switching.
You see the options, not just our pick.
Every tender comes back to you as a clear comparison: each suitable supplier, term, unit rate, standing charge and estimated annual cost side by side, with our recommendation and the reasons for it.
We contract with 17 major energy companies, who all bring different skills and pricing. In our experience, prices can vary by up to 28% between the highest and lowest quote for the same client, which is why we always tender widely. The full list is available on request.

Are your energy invoices right?
Business energy invoices are often wrong, usually because of supplier billing errors or problems with automated meter readings. Most finance teams check them by hand, without the specialist knowledge to spot what's missing.
Our invoice validation service checks every invoice against your actual meter data, site by site, and catches mistakes before you pay.
What invoice validation gives you
- Every invoice checked against real meter data
- Site-by-site checks, down to half-hourly
- Errors caught before they're paid
- Validated data for carbon reporting
- A dedicated customer success manager
- Works alongside your current contract and broker

How much does it cost to use Smart Source Savings?
There's no upfront fee. Like most brokers, we're paid a commission by the supplier you choose, built into the price you pay. We'll always explain how we're paid, and confirm it in writing, before you sign.
Can you help if I'm already in a contract?
Yes. We can review it now, check your bills for overcharges, and line up your next contract well ahead of your end date.
Which suppliers do you work with?
We contract with 17 major energy companies, who all bring different skills and pricing. We'll share the full list on request.
What is a Letter of Authority?
A simple form that lets us talk to suppliers on your behalf and request quotes. It doesn't commit you to switching.
How far back can you check for overcharges?
Up to six years. We look for billing errors, incorrect meter data, wrong tariffs and charges you shouldn't be paying.
Do you work with businesses nationwide?
Yes. We work with businesses nationwide, by phone, email and video call, and can meet in person around London and Hertfordshire.
