    projected net savings over 25 years

  • 1,125

The challenge

For PES, energy is a major operating cost. The plastic components manufacturer wanted to reduce that cost while advancing its sustainability ambitions, without interrupting production.

The CH Group difference

PES had already received installer proposals. CH Group broadened the options, introducing several contractors and comparing their offers alongside the existing proposals. A structured, pragmatic approach gave PES a clearer basis for choosing the right partner.

From comparison to completion

Following a site survey, PES appointed a CH Group-introduced installer for its competitive commercial offer, professional approach and experience in minor roof repairs. A contract was signed and the project moved into delivery.

The challenge

Merlin had already engaged with several companies about its solar and roofing project. With a substantial roof upgrade forming part of the works, the business needed clarity on scope, comparable proposals and confidence in its chosen contractor.

The CH Group difference

CH Group introduced three suitable contractors to one agreed brief, giving Merlin three like-for-like options. This made the commercial comparison clearer and helped the business select a delivery partner with confidence.

From comparison to completion

Merlin progressed to a site survey with its preferred CH Group-approved installer. Following quality and assurance checks, a contract was signed for the combined solar and roofing installation.

Plant & machinery hire, Bristol

The challenge

As its plant and machinery hire business expanded, Kelston Sparks wanted to control rising energy costs at its owned Bristol site. With sustainability deadlines approaching, it needed a practical solution that could deliver tangible value.

The CH Group difference

Earlier solar enquiries had left the business without a common basis for comparison. CH Group brought clarity through a structured tender: three suitable contractors, one consistent brief and three comparable proposals. Kelston Sparks could assess its options with confidence.

From comparison to completion

Kelston Sparks invited all three contractors to visit the site before selecting its preferred installer. The contract was awarded just 22 days after the site survey, turning a previously uncertain decision into a clear route to delivery.
