James Gibb

Who They Are

James Gibb is one of the UK’s largest property factoring businesses, managing hundreds of residential sites across a complex, high-volume estate.

With thousands of meters, multiple suppliers and contracts renewing at different times, the administrative demands of energy management are considerable. Internal teams have other priorities.

What they needed was a partner who could take full ownership of energy — and keep things running properly in the background.

The Challenge

A portfolio this size brings challenges that build up over time.

Many sites rely on estimated reads. Across an estate this large, accurate meter data is difficult to obtain consistently. Left unchecked, that leads to billing inaccuracies, data mismatches and money owed back that is hard to identify and recover.

Alongside billing, James Gibb needed structured support for:

  • Change of Tenancy (COT) processing across the portfolio
  • Competitive, well-run tender management
  • Clear and reliable day-to-day communication
  • Billing data formatted correctly for internal systems

How We Changed Energy Together

Indigo Swan supports James Gibb across both procurement and ongoing portfolio management, acting as a dedicated extension of their team.

Energy Procurement

We run competitive tenders across the portfolio, monitoring the market and placing contracts at the right time.

Our role is to make procurement straightforward. Clear guidance, considered timing and strong supplier engagement — so each contract is placed with confidence.

Energy Management
A dedicated account manager handles day-to-day communication across the portfolio — always reachable, always across the detail.

This year, 748 cases have been raised and 729 closed, with around 300 being actively worked at any one time.

Case management covers:

  • Bill validation — rates, periods and correct meter reads
  • Resolution of overestimated or incorrect bills
  • Query management with suppliers
  • Change of Tenancy processing
  • Smart meter support and commissioning
  • Group billing: converting invoices into the correct internal format and automating uploads

Regular strategic reviews keep the partnership on track — covering performance, upcoming renewals, data accuracy and where improvements can be made.

This partnership reflects Indigo Swan’s wider expertise in supporting multi-site property and residential portfolio organisations with energy procurement and ongoing management across the UK.

The Impact

Financial Impact

  • Substantial year on year savings delivered through competitive procurement and billing accuracy
  • Significant cost recovery through accurate bill validation and identification of overestimated billing

Across a portfolio this size, billing accuracy has a direct financial consequence. Recovering what is owed and preventing future overcharging adds up significantly over time.

Operational Impact

  • High-volume case management handled consistently
  • Automated group billing removing significant administrative burden
  • Improved meter read accuracy and data confidence
  • Structured COT management across the estate
  • Reduced internal administration and resource pressure

Energy is managed consistently and carefully, so James Gibb’s teams can focus on what they do best.

Why They Value the Partnership

James Gibb values Indigo Swan because we work as part of their team — not as a supplier at arm’s length.

We provide:

  • A dedicated account manager, always accessible
  • Reliable case handling across high volumes
  • Structured procurement and tender management
  • Automated billing that reduces the administrative load
  • Confidence that complex issues are being picked up and resolved

For property factoring businesses managing hundreds of sites, having an energy partner who understands the scale and keeps things properly looked after makes a real difference.

That’s what we mean when we say we’re changing energy together.
