Winter heating tips from a Gas Safe engineer

Winter heating tips you can trust — practical advice from a Gas Safe engineer with 16 years’ experience keeping Hampshire homes warm. Preparing your heating system before the cold sets in and carrying out a few simple checks through the season will keep your home comfortable, reduce the risk of breakdowns and help control energy use.

Prepare your heating system before winter

When temperatures drop your boiler works harder and the chances of a fault increase. A little planning now avoids the worst of winter disruption. These steps focus on efficiency, safety and simple maintenance you can do yourself or arrange through a professional.

1. Book an annual boiler service early

Annual servicing keeps your boiler running efficiently and safely. A qualified engineer inspects components, cleans where necessary and spots wear before it becomes a failure. Book your service in the autumn when engineers have more availability — this reduces the likelihood of emergency call-outs during cold snaps and helps your system perform at peak efficiency throughout winter.

2. Bleed radiators to restore even heat

Cold tops and warm bottoms on radiators are usually a sign of trapped air. Bleeding a radiator releases that air so hot water can circulate properly. You’ll need a radiator bleed key, which is inexpensive and widely available. Start with radiators furthest from the boiler and work back towards it; you’ll hear a hiss as air escapes, and should close the valve once water appears. For whole-system bleeding or if you’re unsure, consult a Gas Safe engineer — some procedures are best left to professionals.

3. Use your thermostat sensibly

Set your thermostat to a comfortable band — typically within the high teens to low twenties — and avoid overheating rooms. Reducing the set temperature by a single degree can lead to a noticeable reduction in energy use. A programmable or smart thermostat delivers further savings by lowering temperature when you’re out or asleep and learning your household routine to avoid wasted heating.

4. Insulate exposed pipes

Heat lost from exposed heating pipes reduces system efficiency and delays hot water delivery to distant radiators. Foam pipe insulation is a quick, low-cost upgrade that’s particularly valuable in unheated spaces such as lofts, basements and along external walls. The result is faster warming of radiators and reduced demand on your boiler.

5. Check boiler pressure regularly

Most domestic boilers should run at a pressure within a set operating range — consult your boiler manual for the exact figure, commonly around the lower end of the gauge. If pressure is persistently low it can prevent the boiler from heating correctly or cause shutdowns. Monthly pressure checks through winter help catch leaks or system issues early; persistent low pressure warrants a Gas Safe engineer’s inspection.

6. Maintain ventilation and carbon monoxide safety

Insulation and draught-proofing are important, but never compromise ventilation to the boiler. Blocked vents or sealed airbricks can create a carbon monoxide risk. Keep vents clear, fit and test carbon monoxide detectors, and raise any ventilation concerns with your engineer during a service.

7. Respond to leaks promptly

Even a small leak from a boiler or pipework means water and heat are being lost. Puddles or damp patches should be investigated straight away — what seems minor can quickly cause component damage and larger repairs if left unattended. Regular inspections during an annual service help identify developing faults.

Service plans and emergency cover

Consider a service plan if you value predictable maintenance and quicker access to help. MBW’s Bronze, Silver and Gold plans include annual servicing and safety checks, with the higher levels offering 24-hour emergency cover and repair discounts. For many households, the reassurance of emergency cover and reduced labour rates offsets the plan cost, particularly during winter when breakdowns are more disruptive.

Routine checks to keep on your winter checklist

• Monthly pressure check: Keep an eye on the boiler gauge and report steady drops to an engineer.
• Bleed radiators: Tackle individual cold radiators yourself or follow guidance from our radiator bleeding guide: How to bleed a radiator.
• Look for leaks: Damp or puddles near pipework or the boiler need prompt attention.
• Carbon monoxide detectors: Test detectors regularly and replace batteries as needed.

When to call a Gas Safe engineer

Call a professional if you notice persistent low pressure, unexplained leaks, strange noises from the boiler, or if safety devices such as carbon monoxide alarms activate.

Keep winter manageable and comfortable

Simple actions — timely servicing, sensible thermostat use, radiator bleeding and basic insulation — make a real difference to comfort and running costs.
