Pharmacy Storage Heating Requirements: Keeping Medicines in Range in North East Premises

Pharmacy storage heating requirements come down to one thing: keeping every medicine within the storage conditions on its label, and being able to show that you did. No statute sets a single "pharmacy temperature", so the heating system has to be designed around the products you hold, the building you occupy and the records you keep.

For pharmacies across Newcastle, Sunderland, Middlesbrough and the wider North East, that means thinking about more than whether the shop floor feels warm. Stockrooms, dispensaries, fridges and plant rooms all behave differently, and a North East winter tests all of them. This article sets out what the standards expect, where heating commonly goes wrong, and how a well-maintained commercial boiler system supports compliance.

What Temperature Range Do Medicines Need to Stay In?

The range comes from the product, not from the building. Each licensed medicine carries storage conditions in its summary of product characteristics and on its packaging. Many are labelled "do not store above 25°C" or "below 30°C", while refrigerated lines are held at 2°C to 8°C. Some products have other conditions, such as protection from light, moisture or freezing. As of 2026, you should check specific products against the current MHRA and Royal Pharmaceutical Society guidance on medicines storage, as well as the label itself.

Three storage types, three heating relationships

  • Room-temperature storage: the stockroom and dispensary shelves. This is where building heating has the most direct effect, mainly by keeping stock above any low-temperature limits and by not pushing it over the upper limit.
  • Cold-chain storage: pharmacy fridges. Cold chain means the unbroken refrigerated storage of products from manufacture to supply. Fridges do their own cooling, but they work harder in a warm room, and a hot plant room next door can affect them.
  • Controlled drugs cabinets: these are governed mainly by security requirements, but the contents still carry label conditions, and the cabinet sits in a room whose temperature you must manage.

There is no single statutory "pharmacy heating temperature". The duty is to prevent medicines being stored outside their labelled limits. The General Pharmaceutical Council (GPhC) inspects registered pharmacies against its standards for registered pharmacies, which expect medicines to be stored securely and appropriately, and inspectors will want evidence that storage conditions are controlled. Heating is one of the tools for meeting that expectation, and records are how you prove it.

Where Heating Gets It Wrong: Cold Spots, Overheating and Overnight Setbacks

Overheating is the more common heating-related risk. A stockroom backing onto a plant room, a shelf beside a flue run or radiator pipework, or a south-facing dispensary on a sunny day can all drift above 25°C. Heating that is simply "on" for long periods can make this worse, especially where radiators in small rooms cannot be individually controlled.

Cold is a genuine risk too. Unheated back rooms, loading areas and older North East buildings with solid walls can fall low on winter nights. Some products, including certain liquids, creams and injectables, can be damaged by freezing, so check the label for any "do not freeze" instruction rather than assuming a cool room is a safe one.

Setbacks and failures when nobody is there

A setback is a timed reduction in heating when the building is closed. Setbacks save fuel, but if the programme drops the stockroom too far, or the boiler fails over a weekend or bank holiday, stock can spend many hours out of range with nobody present to notice. An excursion is the term for any period when stock goes outside its labelled temperature, and the length and severity of it determine whether the stock can still be used.

An illustrative scenario

Imagine a pharmacy in a converted terrace on Tyneside. A single heating circuit serves the whole building. The dispensary at the front, with its computers and staff, stays warm, so the thermostat there is satisfied and the boiler cycles off. The stockroom at the rear, with an external solid wall and no radiator of its own, sits several degrees colder. Nobody notices until a cold snap and a data logger reading show the problem. The fault is not the boiler. It is the lack of zoning and monitoring.

The reverse is equally possible: a rear stockroom beside the boiler and its pipework running warm all year. In both cases, the cure starts with knowing what each room is actually doing.

Workplace Temperature Law and Staff Comfort Alongside Stock Storage

Separate from medicines storage, the Workplace (Health, Safety and Welfare) Regulations 1992 require a reasonable temperature in indoor workplaces. The accompanying Approved Code of Practice suggests a minimum of 16°C, or 13°C where much of the work involves rigorous physical effort. There is no legal maximum, though the HSE expects employers to keep conditions reasonable. Check the current HSE wording as of 2026 before relying on these figures in your own risk assessments.

The practical difficulty is that staff comfort and stock storage targets differ. A dispensary kept at a comfortable working temperature may be fine for stock, but a public area heated generously on a cold morning is not a model for the stockroom. One thermostat setting rarely satisfies both, which makes this a zoning question rather than a matter of turning a single dial up or down.

The Health and Safety at Work Act 1974 adds general duties on employers to provide a safe working environment so far as is reasonably practicable. That covers heating systems and gas appliances: a boiler that is poorly maintained, or a flue that is damaged, is a safety issue for staff and customers before it is a stock issue.

Who is responsible for the boiler?

Many pharmacies rent units in health centres, retail parades or high-street terraces. Check your lease to see who is responsible for the boiler, the controls and the gas pipework, and who arranges servicing. Where the landlord owns the plant but you carry the stock risk, agree in writing how faults are reported, how quickly they must be attended to, and what happens out of hours. Confusion over responsibility is a common reason repairs are delayed.

Designing Commercial Heating for Medicine Storage: Zoning, Controls and Monitoring

Good design makes the heating predictable and makes any departure visible. The main elements are:

  • Zoning and thermostatic controls: separate zones for the stockroom, dispensary and public area, each with its own thermostat or programmer, so each can be set to suit its purpose. Thermostatic radiator valves help, but dedicated zone controls give firmer control.
  • Temperature monitoring: data loggers or min/max thermometers in the stockroom and inside each fridge, with readings recorded and kept. Calibrate or replace devices as the manufacturer advises.
  • Out-of-hours alerts: remote alarms that message a named person if the building rises or falls outside set limits. These are especially useful over weekends and bank holidays.
  • Summer cooling: ventilation or air conditioning where needed.

Monitoring is separate from the boiler, but it tells you when heating is the cause. A stockroom that falls overnight in winter while the dispensary holds steady points to zoning or a setback programme. A reading that climbs on a mild afternoon points to solar gain or a hot plant room instead.

Heating alone cannot keep a stockroom below 25°C. A boiler can only add heat, so summer control depends on ventilation, shading or air conditioning, and your heating plan should sit alongside a cooling plan rather than replace one.

Any change to a boiler, flue or gas pipework must be carried out by a Gas Safe registered engineer. Never attempt it yourself or use an unregistered contractor. You can confirm an engineer's registration and the types of work they are qualified for on the Gas Safe Register, and you should ask to see their ID card before work begins. Controls upgrades that involve the gas appliance also fall within this requirement.

Boiler Maintenance and Gas Safety Duties for Pharmacy Premises

Under the Gas Safety (Installation and Use) Regulations 1998, landlords must have gas appliances and flues in rented premises checked annually by a Gas Safe registered engineer. Employers and those in control of premises have wider duties under the Health and Safety at Work Act 1974 to keep gas appliances safe. The legal position depends on your lease and on who controls the plant, so confirm it for your own tenancy. Regardless of who is legally responsible, annual servicing is sound practice for every commercial boiler, and it is not only a landlord's concern.

What an annual inspection covers

In practice, a commercial boiler inspection typically includes combustion and flue checks, testing of safety devices, and checks on controls and thermostat operation. That last item matters to pharmacies. A thermostat that reads inaccurately or a control that fails to respond can leave a stockroom outside its range while the boiler appears to be working normally.

Timing in the North East

Book servicing before demand peaks. In Newcastle, Sunderland, Teesside and Northumberland, September to October is the sensible window, since engineers are busiest once the first cold weeks arrive and a fault found in December is harder to fit in. Today, in mid-October 2026, is a good moment to check whether your service is due.

Carbon monoxide and gas leaks

Faulty gas appliances can produce carbon monoxide, which is why flue checks matter. If you suspect a gas leak, leave the area immediately and call the National Gas Emergency Service on 0800 111 999. Do not operate switches or attempt any repair.

Commercial Boiler Solutions provides commercial boiler maintenance and annual inspections across the region through Gas Safe registered engineers.

What to Do When the Boiler Fails and Stock Is at Risk

Act in a set order, and write each step down.

  1. Check the record. Read the data logger or min/max thermometer, note when the temperature went out of range, how far, and for how long. Start an incident log with times and actions.
  2. Quarantine affected stock. Separate it and mark it clearly. Do not assume it is usable.
  3. Seek guidance. Contact the product manufacturers and your superintendent pharmacist before supplying anything. Manufacturers can advise on whether a given excursion is acceptable for a given product. As of 2026, check current MHRA and RPS guidance on temperature excursions as well.
  4. Call a Gas Safe registered engineer. Commercial Boiler Solutions offers emergency callouts and same-day service across Newcastle, Sunderland, Middlesbrough and the wider North East. Do not attempt to restart or repair a faulty gas boiler yourself.

If you smell gas at any point, leave the building and call 0800 111 999 first.

Plan before it happens

Keep an emergency contact list that includes your engineer, superintendent pharmacist, landlord or managing agent, and key suppliers. Decide in advance how you would temporarily protect stock, for example by moving it to a suitable alternative site or an unaffected room. Any backup heating should not rely on portable gas heaters, which bring their own carbon monoxide and fire risks in an enclosed space. Electric alternatives need a safety check of their own. A service contract with priority response also shortens the time stock sits at risk.

Heating That Supports the Label, Not Just the Thermostat

The principle is simple: the label sets the limits, and the heating must support them rather than undermine them. That means zoned controls, sensible setbacks, monitoring you can evidence, cooling for summer, and a boiler that has been serviced by a Gas Safe registered engineer before winter arrives.
