What 001 ltd does

001 Ltd is an independent commercial utility consultancy headquartered in St Albans, Hertfordshire, founded in 2000 and operating under the legal name 001 Limited. The firm helps UK businesses reduce and manage their utility costs across electricity, gas, water, and telecoms through a layered offering built around three core services: Business Energy Procurement (negotiating supply contracts with a wide panel of partner suppliers including E.on, SSE, British Gas, Shell Energy, NPower, Engie, Total Energies, Drax, Good Energy, and others), Historic Energy Audit (recovery of overcharging across up to six years of past bills on a success-fee basis), New Connections, and Energy Bureau Services (ongoing bill validation, consumption reporting, and portfolio management). Adjacent offerings include Business Water Rates, Green Energy procurement, LED Lighting (no-upfront-cost installation), Rent Rates Leases advisory, Telecoms procurement, SECR compliance, and Energy Consumption Analysis. The company positions itself as fully independent — explicitly distinguishing itself from tied supplier agents — and sells primarily through a direct field sales model supported by sector-specialised landing pages for Leisure, Retail, Care Homes, Multi-Site organisations, Construction, and Charities, plus an introducer/partner programme that pays a £100 bounty per qualifying client and 10% of ongoing revenue.

The business operates on three revenue streams: supplier commissions paid by energy, water, and telecoms providers for introductions (transaction-fee model), success-based customer fees for historic audit recoveries (outcome-based model), and ongoing management fees for energy bureau services (subscription model). Per the available case studies, individual client engagements produce measurable savings in the range of £7,500 to over £426,000, and the company publicly reports more than £25 million in cumulative client recoveries through its historic audit service. 001 is a member of Ofgem's ADR Microbusiness Scheme (membership C35001L01) and is led by Managing Director John Hamshere and Director Jane Hamshere. The firm remains privately held with no disclosed external investment or acquisition activity, employs 11–50 people, and serves hundreds of UK businesses across its six verticals.

Underlying technology is human-advisory rather than platform-based: no proprietary software, AI/ML capabilities, apps, SDKs, or API integrations are disclosed across the input data. The competitive proposition relies on expert human account managers, market intelligence, supplier relationships cultivated over more than two decades, and the regulatory and reputational standing conferred by independence and Ofgem scheme membership. Geographic scope is the United Kingdom only, with no international footprint, and the company's growth signals are concentrated in product surface expansion (water, telecoms, LED, SECR, rent advisory) and channel formalisation (introducer programme) rather than geographic diversification.

1. Supplier Commission: 001 receives commission payments from utility suppliers (E.on, SSE, British Gas, Shell Energy, etc.) for introducing and securing supply contracts between the supplier and a customer. Commission rates are negotiated with each supplier.
2. Customer Fee (Success-Based): Fees charged to customers only when recoveries or savings are made from historic overcharging audits. The historic energy audit reviews the last six years of utility bills. No upfront fees for this service.
3. Customer Fee (Ongoing Management): Ongoing fees for energy bureau services including bill validation, portfolio management, consumption reporting, and procurement management. Charged as a percentage of revenue received (10% to introducers) or as agreed service fees.

Scale indicators5 records

Recent moves6 records

Broad incumbents

• British Gas Business: Largest UK business energy supplier and incumbent utility provider. One of 001's core supplier partners but also a competitor offering direct procurement, account management, and bureau-style services at scale to enterprise customers.
• EDF Energy Business: Major UK business electricity and gas supplier offering direct procurement, green tariffs, and multi-site account management. Competes with 001 across the same multi-site customer base while also being a potential supplier partner.
• SSE Business Energy: Large UK energy supplier with a dedicated business division providing electricity, gas, and water services to multi-site commercial customers. Overlaps 001's enterprise customer base and procurement focus.

Direct peers

• Love Energy Savings: UK business energy price comparison and broker service. Direct competitor for small and mid-market business energy procurement with multi-utility offerings, overlapping 001's core procurement and bill management services.
• Crown Gas & Power: UK business gas and electricity supplier that also operates broker partnerships. Listed as one of 001's supplier partners but also competes as a vertically integrated energy provider for the same multi-site customers.
• Switch Gas and Electric: UK business energy switching broker for SMEs and mid-market. Comparable customer base and core procurement service to 001, with similar commission-based revenue model across the UK supplier market.
• Utility Bidder: UK commercial energy broker focused on switching and procurement for businesses. Operates a similar intermediary model to 001, introducing customers to supplier panels and earning commission on contracts secured.
• Bionic: UK business utility broker and comparison platform for SMEs. Directly comparable to 001 in target customer (UK multi-site businesses) and core offering (energy procurement and contract negotiation), but differentiates via proprietary digital technology versus 001's consultancy-led model.
• Opus Energy: UK business energy supplier (now part of Shell Energy) focused on SMEs and mid-market. Competes with 001 both directly as a supplier and indirectly through its own broker/champion partnerships for the same customer segments.

Emerging players

• Limejump: UK technology-driven energy supplier and platform (now part of Open Energi / Shell) targeting commercial customers with smart procurement, flexibility services, and renewable PPAs. Represents the digital-native evolution of the traditional broker model 001 operates in.
