Changes are being made to a £120 million scheme for a “clean energy” complex in Keighley.

But those behind the pioneering project, which could create around 500 jobs, say the proposed amendments will not majorly affect the initiative.

Permission is being sought from Bradford Council – which is still to rule on the original planning application – to move a chimney stack and reduce an office block from four to two storeys, to conform with health and safety requirements.

“These are the final changes and we can then move forward with the scheme,” said agent John Steel, of JO Steel Consulting.
