UK telecoms data centre cooling upgrade cuts costs

Secure I.T. Environments has completed a cooling infrastructure upgrade for a UK telecommunications operator’s data centre, a project expected to cut annual energy costs by 69%.
The work involved replacing ageing air conditioning equipment at an offshore telecoms site that operates continuously. The installation was completed in a live environment without disrupting services, with uninterrupted operations maintained throughout the project.
The customer has not been named, but is described as one of the UK’s leading telecommunications providers. The site’s previous cooling units were nearly 20 years old, prompting a replacement programme to reduce running costs and modernise critical infrastructure.
The upgrade delivered a Cooling PUE of 1.13 and is projected to achieve return on investment in 1.29 years. The figures underline the financial case for replacing older plant in data halls, where electricity remains a major operating expense.
The installation included three indoor Multi-DENCO DMF065D downflow air conditioning units. Each provides 59.7kW of net sensible cooling, with the range operating under typical conditions at a sensible heat ratio of 1.0.
The new system uses free cooling infrastructure and replaces end-of-life equipment that had supported a mission-critical telecoms environment. Upgrades at sites like this can be difficult because equipment must be removed and replaced while digital services continue running around the clock.
Secure I.T. Environments focuses on UK data centre design and build projects, including modular, containerised and micro data centres, as well as mechanical and electrical infrastructure. Its work spans private sector customers as well as healthcare, education and government organisations.
Cooling systems have become a growing focus for operators seeking to reduce energy use in facilities that support telecoms networks, cloud services and other digital workloads. Older air conditioning systems can be costly to maintain and less efficient than newer alternatives, particularly at sites where demand varies over time and equipment must respond to changing thermal loads.
Precision cooling suppliers have increasingly introduced inverter-driven systems designed to match output more closely to real-time demand. In this case, the selected units use an internal inverter compressor, electronic expansion valve and fans to vary output and improve efficiency during partial-load operation.
The project also reflects the operational pressure on telecoms providers to maintain network and service continuity during infrastructure changes. Data centre work in a 24/7 setting often requires phased installation, careful sequencing and contingency planning, especially when cooling systems are essential to keeping server and network equipment within safe operating conditions.
Efficiency focus
The project was presented as an example of how facilities operators can update core plant without interrupting service. That is particularly relevant in the telecoms sector, where outages can affect both retail and wholesale customers and quickly trigger wider operational problems.
Chris Wellfair outlined the rationale for such projects.
“The advances in data centre cooling equipment deliver substantially improved energy efficiency and a rapid return on investment. These projects should be seen as investments in resilience and reduced operational costs and, delivered with the right partner, can take place with no breaks in service and minimal disruption,” said Chris Wellfair, Projects Director, Secure I.T. Environments.

Mouse droppings found in Oxford city Chinese restaurant
Ten Seconds Yunnan Rice Noodle in New Inn Hall Street was inspected by Oxford City Council on May 26.
Inspectors subsequently handed the Chinese restaurant a rating of two out of five, meaning “improvement necessary”.
According to the report, received by the Oxford Mail after a Freedom of Information request submission, officers identified a series of concerns, including evidence of mouse activity.
The report states that mouse droppings were found throughout the business in two food storage rooms and the bar area.
In one of the storage areas, mouse activity was present where noodles were kept in plastic carrier bags and potatoes and onion were left in the open.

Inspectors said pest-proofing measures were “not great” and identified a hole beneath a sink in the bar area which could potentially allow pests to enter the premises.
In the report, the inspector said: “At the time of the inspection, I observed a number of historic mouse dropping in both the food storage areas.
“The most recent pest control report mentions no mouse activity in any of the food storage areas.
“All areas where food is prepared and stored must be kept clean and capable of being kept clean. This is so that pests are not attracted into your premises and the risk of food being contaminated by dirt is minimised.”
They advised the owner to remove all historic mouse droppings within the food business and continue to identify any issues of pest proofing within a month.

The business was instructed to remove the droppings and improve pest-proofing measures where previous temporary work had failed.
Food storage issues were also highlighted during the inspection.
In an “overfilled” fridge, officers found raw chicken stored above ready-to-eat foods, including uncovered beans and spring onions, which could cause cross-contamination leading to food poisoning.
That same fridge, which stored items such as cooked rice, chicken ballotine and prawns, was above the required eight degrees, raising concern about food poisoning.
A large number of food containers were also unlabelled, despite the food looking fresh.
The officer insisted a “robust system for ensuring adequate stock rotation” was implemented and recommended all food be kept in sealed, pest-proof containers.

No food-safe sanitiser or disinfectant were available on site, only a kitchen cleaner which they said did not provide adequate disinfection.
Despite the concerns, the report noted there had been a “huge improvement” in cleaning standards since the restaurant’s previous inspection.
The business also had a food safety management system in place and a pest control contract with Pure Pest Solutions.
The council has required a range of improvements, with compliance timescales ranging from one week to one month with a revisit inspection planned.

Oxford startup secures Innovate UK Women in Innovation Award
Oxford-based Peripear has secured an Innovate UK Women in Innovation Award and a £74,974 grant for its development of a wearable device designed to prevent perineal trauma during labour.
The funding will support continued product development ahead of the company’s planned first-in-human study.
Nina van Schaick, co-founder and COO of Peripear as well as a midwife who trained at Oxford Brookes, said: “I’m sure I wasn’t the only one to see this gap.
“I was incredibly lucky to meet my co-founder, Eviatar Natan, right as my frustration about the lack of translation of evidence into practice had peaked.
“There was a proven mechanism that could reduce injuries occurring in up to 90 per cent of vaginal births, and it was being left out of clinical pathways simply because no standardised tool existed to deliver it.”
Peripear is developing what it describes as the world’s first automated perineal thermotherapy wearable, designed to prevent perineal trauma during childbirth.
A perineal thermotherapy wearable is an emerging medical device.
It is a hands‑free warm compress device used on the perineum during the second stage of labour to reduce severe tearing and episiotomies while improving maternal comfort.
Ms van Schaick added: “I’m a farmer’s granddaughter, and when I started practising over 14 years ago, I asked: where is the tool I need to implement this evidence? I looked around and realised we were still asking clinicians to improvise.
“Peripear is what happens when the person who has lived the problem, both personally and professionally, meets the person who can help her build the solution.”

UK bike manufacturer on brink of £30m collapse after 139 years
The company behind bikemaker Raleigh, which was founded 139 years ago and has supplied bikes to the UK’s cycling city of Oxford over the years, has filed to appoint administrators.
Accell UK and Ireland, part of Netherlands-based Accell Group, filed a notice of intention to appoint administrators as the wider group kickstarted insolvency proceedings.
This follows a difficult spell for Nottinghamshire-based Raleigh, which confirmed job cuts in 2024 before reporting a £30m loss in financial accounts published the following year.

The boss of Accell said it was a “deeply sad and frustrating situation” and that it had “tirelessly explored” every option for the future of the cycling business.
The company bought Raleigh in 2012 for around 100 million US dollars (£74 million), adding to its roster of bike brands throughout Europe including Haibike, Winora and Ghost.
Raleigh was founded in Nottingham in 1887 and was well-known for its Chopper model, which featured extended handlebars and is now part of its “retro” range.
It no longer manufactures bikes from Nottingham, and its head office has moved to Eastwood, Nottinghamshire, while the company has shifted to selling electric bikes under Accell’s ownership.

Accell went through a restructuring in February, securing additional funding from shareholders and lenders and reducing debts.
The group said it had since “explored every possible avenue” for its future, including discussions with potential buyers, but that it had not been possible to find a solution which means the business can continue operating.
It has therefore initiated insolvency proceedings in the Netherlands.
Accell’s chief executive Jonas Nilsson said: “This is a deeply sad and frustrating situation given all the hard work and everything we have achieved, with the support of shareholders and lenders, to restructure Accell’s operations and finances.
“It is an especially difficult moment for our employees, creditors, customers, suppliers, and partners.

“Every realistic option for the future of the business has been tirelessly explored, and none have resulted in a solution to continue the Group in its current form.
“Our immediate focus is to support an orderly process, provide clarity wherever possible, and work with the relevant court-appointed administrators to preserve viable activities and employment where circumstances allow.”
At its 1970s height, Raleigh employed more than 13,000 people across the UK, with around 8,000 working at its various Triumph Road sites in Nottingham.
The former factory land later became the University of Nottingham’s Jubilee Campus.
Raleigh subsequently moved its headquarters to Church Street in Eastwood, before leaving that site and relocating to Durban House in 2024.
