During the warm summer months, your conservatory is an inviting extension of your living space however, during the colder winter months when there is little sunshine it can be uninviting.

In this article, we’re going to look at how to make your conservatory warmer and retain heat, including insulation upgrades, heating solutions, and cosy touches.

Insulation Upgrades: Building Your Warmth Fortress

There are several ways that you can transform your conservatory from a seasonal sunroom into a room that can be enjoyed all year round, while also reducing energy bills.

  • Double/Triple Glazing: Double and triple-glazed windows are very energy efficient as they trap heat and make a conservatory warmer. All of our conservatories come with the benefit of toughened double-glazed units throughout, keeping warmth in and noise out.
  • Roof Insulation and Ventilation: For maximum insulation, consider conservatory roof insulation. If your roof is made entirely of glass, rather than a solid tiled roof, you’re more likely to lose heat. Tiles can provide more insulation and if it’s in your budget this is a good option to consider.
  • Another option is internal reflective blinds. In winter these will reduce heat transfer, helping to keep your conservatory warm in the winter and cool in the summer.
  • Seal the Gaps: Draught proof your conservatory to help prevent heat loss. A cost-effective way to do this is to use draught excluders at the bottom of a door. You should also fill any gaps around the window frames using self-adhesive foam strips to prevent draughts and cold air from entering conservatories.

Warming the Atmosphere: Heating Solutions for the Win

If a conservatory or garden room is cold in winter, there are ways to keep it warm.

  • Underfloor Heating: Electric or water based underfloor heating can provide instant heat and warm a cold floor. Under floor heating is a lovely luxury and will evenly distribute warmth throughout your conservatory.
  • Radiators: Adding electric radiators is also a good heating solution and thermostatic controls are very efficient, helping to reduce energy costs.
  • Wall-Mounted Heaters: Wall-mounted heaters are an excellent option for targeted warmth in your conservatory when the sun is scarce in winter.
  • Portable Heaters: Stay warmer with a low-maintenance portable heater. Perfect for increasing the temperature on chilly evenings when you still want to enjoy your conservatory.

Cosy Touches for a Warm Sanctuary:

As well as heating solutions, don’t forget to add cosy touches to create a warm sanctuary, such as:

  • Thermal curtains and blinds for extra warmth.
  • Soft furnishings, will not only add a stylish touch to your room but will also make it feel cosy and inviting. Don’t forget about your flooring too. Consider carpet tiles or rungs for extra warmth.
  • Warm-toned lighting will create a cosy atmosphere, perfect for unwinding after a busy day.


Conservatories can be enjoyed all year round with the right combination of energy-efficient heating solutions and cosy touches. An older conservatory can be upgraded in cost-effective ways to improve its energy efficiency and a new conservatory project is a great opportunity to put heating solutions in place.
