Britain's largest garden centre operator says environmental regulations and rising business costs are putting further pressure on firms

Britain's largest garden centre chain has warned that environmental regulations championed by Ed Miliband could hit the business with millions of pounds of extra costs.

Alan Roper, managing director of Blue Diamond, which operates 54 sites across the UK, criticised Labour's approach to climate policy.

He accused Mr Miliband of turning it into a "personal achievement project" without fully considering the pressures facing British businesses.

"We've started to seriously look at the costs now, because we're only a few years away. It's going to be seven figures — you're talking millions," Mr Roper said.

His criticism centres on proposed Net Zero efficiency requirements that would impose stricter Energy Performance Certificate standards on commercial properties by 2031.

Mr Roper said the regulations would present a significant challenge for Blue Diamond because of the nature of its estate, which includes numerous glasshouse structures that are essential to garden centre operations and are costly and difficult to insulate to the required standards.

He questioned the rationale behind imposing substantial penalties on businesses that fail to comply with the proposed rules while the Government continues to import gas from overseas at elevated prices.

"I'd love Ed Miliband to be in an interview where I could hear him answer the question: 'Why is it okay for us to buy gas at hugely expensive prices when we could be getting the balance right by drilling oil and gas?'" he said.

Mr Roper also challenged the UK's broader decarbonisation strategy.

"We're one per cent of the world's emissions. I mean, what are we trying to prove?" he said.

His concerns extend beyond environmental policy to Labour's wider approach to business regulation, with Mr Roper describing increases to employer National Insurance contributions and above-inflation rises to the minimum wage as "horrendous".

"I know what they're trying to achieve, but there have been many good intentions that end in destruction."

According to Mr Roper, the combined impact of higher wage costs and tax changes has reduced Blue Diamond's profits by more than £12million over the past four years.

He also criticised the Employment Rights Act 2025, which introduced statutory sick pay from the first day of illness.

"Somebody now can phone in and say I've got a headache, and then you have to pay them. It's crazy," he said.

Despite the additional pressures, Blue Diamond has reported strong financial results in recent years.

Turnover increased by 19 per cent to £395million in 2025, while pre-tax profits rose by 44 per cent to £31.4million.

The company has also grown sales by almost 90 per cent over the past five years.

Mr Roper said rising shipping costs linked to tensions in the Middle East were creating fresh challenges for retailers.

Container rates, which had fallen back to around $2,000 after reaching as much as $15,000 during the pandemic, have recently increased by between $3,500 and $4,000 per container following disruption linked to the closure of the Strait of Hormuz.

Mr Roper warned that businesses would struggle to absorb the additional costs indefinitely.

"We're now having to look at our pricing because we can't absorb it," he said.

"The consumer always ends up having to pay — otherwise, businesses go out of business."
