Choosing a cooling system consultancy feels a bit like hiring a solicitor – you don’t do it often, and when you do, the stakes are high. Get it right, and your facility runs smoothly for decades. Get it wrong, and you’re looking at production downtime, compliance headaches, and energy bills that make your finance director wince.
Vistech Cooling Systems has spent over 50 years helping UK manufacturers and data centre operators navigate this exact decision. From FEED studies through to lifecycle support, we’ve seen what separates a genuinely useful consultancy from one that simply ticks boxes. This article gives you 10 questions that separate the two.
Bear with me – these aren’t the obvious questions you’ll find elsewhere. They’re the ones that expose whether a consultancy truly understands your process, your risks, and your long-term goals.
Quick guide: 10 questions for vetting your cooling consultancy
- Do you conduct independent FEED studies before recommending equipment? – Confirms engineering rigour over sales bias

- What ongoing support do you offer post-commissioning? – Reveals lifecycle commitment
How we selected these questions
These questions emerged from real project experiences across hundreds of industrial sites across the UK – from cement factories with 14 cooling towers to data centres where a single hour of downtime costs more than the entire cooling system. They were selected based on five criteria: risk exposure, engineering depth, accountability clarity, measurable outcomes, and long-term value – all within a UK-specific regulatory and environmental context.
The 10 questions every UK facilities manager should ask
1. Do you conduct independent FEED studies before recommending equipment?
A Front-End Engineering Design (FEED) study defines the engineering scope, models system performance, and establishes commercial justification before any equipment gets specified. It’s the difference between buying a cooling system and engineering one.
Vistech Cooling Systems delivers FEED studies that include lifecycle cost analysis and cashflow modelling across OPEX lease, lease-purchase, and CAPEX routes. This approach replaces guesswork with data – giving you evidence to speed CAPEX approval and prevent oversizing.
If a consultancy jumps straight to equipment recommendations without understanding your process cooling duty, heat loads, and future capacity requirements, that’s a red flag. Ask to see examples of previous FEED study outputs.
What to look for in the answer
- Clear methodology for defining cooling duty requirements
- Evidence of process integration, not just equipment selection
- Willingness to recommend alternatives to their own preferred equipment if the data supports it
2. How will you verify ACOP L8 and HSG 274 compliance in your design?
Under UK law, if you operate a cooling tower or evaporative condenser, you must implement measures to prevent or control legionella risk. The Approved Code of Practice L8 and HSG 274 Part 1 set out the requirements – and they’re not optional.
A competent consultancy should be able to explain exactly how their design addresses access for inspection and maintenance, water treatment programme requirements, and monitoring provisions. As HSG 274 Part 1, Para 1.15 states: “Adequate access must be provided to all parts of the system.”
What to look for in the answer
- Specific references to HSG 274 Part 1 requirements for evaporative cooling systems
- Discussion of how the design enables cleaning, disinfection, and inspection
- Evidence of collaboration with water treatment specialists during design phase
3. Can you model lifecycle costs, not just capital expenditure?
Only about 10% of a cooling system’s lifetime costs come from the initial purchase. The remaining 90% sits in energy consumption, water usage, maintenance, and eventual replacement. A consultancy focused purely on CAPEX may specify equipment that looks attractive upfront but costs significantly more to operate over 20–25 years. Ask for side-by-side cashflow modelling that includes energy, water, maintenance contracts, and anticipated refurbishment.
What to look for in the answer
- Calculation methodology that accounts for energy tariff scenarios
- Water consumption projections including treatment costs
- Maintenance and parts replacement schedules with associated costs
4. What’s your approach to energy efficiency beyond the cooling tower itself?
With industrial processes generating around 46% of business energy bills, the cooling system deserves serious attention. The right consultancy thinks beyond the tower itself – considering pump sizing, variable speed drives, control philosophy, and how the cooling system integrates with your broader process. Fixed-speed pumps fighting control valves cause instability and waste energy, yet this is a common finding on site visits.
What to look for in the answer
- Discussion of VSD fan control for temperature-based modulation
- Consideration of pump hydraulics and circulation system design
- Smart control options that optimise fan and spray setpoints
5. How do you handle noise compliance for planning applications?
Cooling equipment generates noise. Local planning authorities have increasingly strict requirements, and failing to address noise at design stage can result in costly retrofits or operating restrictions. A capable consultancy should assess ambient noise levels, model equipment noise output at boundary positions, and specify appropriate attenuation measures – including low-noise fan selections, acoustic louvres, or operational scheduling through smart controls.
What to look for in the answer
- Experience with noise impact assessments for planning applications
- Range of attenuation options beyond just specifying quieter equipment
- Understanding of day versus night-time noise limits
6. Will you take single-point responsibility for the entire installation?
One of the most common frustrations in facility management: when something goes wrong, the equipment supplier blames the installer, the installer blames the commissioning engineer, and nobody takes ownership. Vistech Cooling Systems takes single responsibility for turnkey projects – from design through manufacture, installation, and commissioning. This means one point of contact, one accountable party, and no finger-pointing when questions arise.
What to look for in the answer
- Clear contractual responsibility boundaries
- Evidence of managing complete projects, not just equipment supply
- Approach to coordinating mechanical, electrical, and civil works
7. What performance data will you capture to validate the design?
If a consultancy promises specific performance outcomes – energy savings, cooling capacity, water efficiency – ask how they’ll prove delivery. Without baseline measurement and post-commissioning monitoring, “improved performance” remains just words. Performance surveys capture live operational data to validate consumption, expose inefficiencies, and strengthen ROI cases for future upgrades.
What to look for in the answer
- Methodology for establishing baseline performance
- Monitoring approach during commissioning and operation
- Willingness to link payment milestones to verified performance
8. How do you address water consumption and ESOS reporting?
If your company qualifies for the Energy Savings Opportunity Scheme (ESOS) – typically over 250 employees, or turnover exceeding £44m with balance sheet above £38m – your cooling system’s energy and water consumption feeds into mandatory reporting. Beyond compliance, water consumption represents real cost and environmental impact. Modern cooling infrastructure can cut water usage by up to 90% compared to traditional evaporative systems in appropriate applications.
What to look for in the answer
- Understanding of ESOS reporting requirements
- Range of options for reducing water consumption (adiabatic coolers, bleed control, filtration)
- Ability to quantify water savings in business case documentation
9. Can you demonstrate experience in my specific industry sector?
A consultancy that’s designed cooling for chemical plants brings different expertise than one focused on data centres or food production. While engineering principles transfer, sector-specific knowledge of process requirements, regulatory nuances, and operational constraints matters. Vistech Cooling Systems has delivered over 1,000 projects across 12+ sectors, including aerospace, pharmaceuticals, distilleries, and data centres.
What to look for in the answer
- Specific case studies from your sector or similar applications
- Understanding of industry-specific regulatory requirements
- References from comparable facilities
10. What ongoing support do you offer post-commissioning?
Cooling towers have typical lifespans of 20–25 years depending on casing material, environmental factors, and maintenance quality. That’s a long relationship with your consultancy. Ask about maintenance contracts, spare parts availability, and responsiveness when issues arise. A consultancy that disappears after commissioning leaves you exposed when the unexpected happens.
What to look for in the answer
- Tailored maintenance packages with clear service level commitments
- Spare parts supply capability and typical lead times
- Remote monitoring options for predictive maintenance

What happens when you skip the consultancy vetting process?
Consider a cement factory with 14 closed-circuit towers cooling kiln jackets. When asked why closed circuit rather than open, nobody could give a clear answer – the original specification had simply been repeated for each installation without questioning whether it was appropriate. This happens when specifications follow defaults rather than engineering analysis. A proper consultancy engagement would have questioned that assumption at the outset, potentially delivering significant savings across all 14 units.
How do you assess a consultancy’s regulatory knowledge?
Regulatory compliance isn’t just about knowing the rules exist – it’s about understanding how they apply to your specific installation. Ask a potential consultancy to walk you through how they’d address ACOP L8 requirements for your planned system. Listen for specifics: do they reference particular paragraphs from HSG 274 Part 1? Can they explain the written control scheme requirements? Do they understand the responsible person role under the regulations? A consultancy that speaks in generalities about “meeting regulations” without demonstrating detailed knowledge should prompt further investigation.

FAQs about cooling design consultancy questions
What is a FEED study in cooling system design?
A FEED study (Front-End Engineering Design) defines the engineering scope, models system performance, and establishes commercial justification before equipment gets specified. Vistech Cooling Systems delivers FEED studies that include lifecycle cost analysis and side-by-side cashflow modelling to support informed decision-making.
Why is ACOP L8 compliance important for cooling towers?
ACOP L8 sets out the legal requirements for controlling legionella bacteria in water systems, including cooling towers. Non-compliance can result in enforcement action, and more importantly, poses genuine health risks. Your consultancy must demonstrate how their design enables ongoing compliance.
How do I verify a consultancy’s claims about energy savings?
Ask for performance monitoring methodology and baseline measurement approaches. Vistech Cooling Systems captures live operational data through performance surveys to validate consumption and expose inefficiencies – giving you evidence rather than estimates.
What sectors does Vistech Cooling Systems work in?
Vistech has delivered projects across 12+ sectors including pharmaceuticals, food and beverage, chemicals, data centres, distilleries, and aerospace. This breadth of experience means we understand sector-specific requirements and regulatory nuances.
Should I choose a consultancy based on equipment brand representation?
Equipment brand matters less than engineering capability and accountability. A consultancy tied to a single manufacturer may recommend their products regardless of fit. Look for independence in FEED studies and willingness to specify appropriate equipment for your specific application.
