Factors That Change the Price
Each design choice affects the final modern conservatory cost. Material quality determines durability and maintenance costs. Size requirements impact foundation and construction costs.
Size and Space
Size affects the modern conservatory cost the most. A 3m x 3m space suits a reading room. Most homes need planning permission for spaces over 4m x 4m. Each square meter adds £1,000 to £2,000 to the total cost. Larger spaces need stronger foundations and more structural support.
Material Options
UPVC frames, a popular choice for modern conservatories, cost between £15,000 to £30,000. These durable frames last 20-25 years, making the modern conservatory cost more manageable over time. Maintenance costs around £100 per year, and color options include white, wood grain, and grey.
Recent studies by the Aluminum Federation show aluminum frames last 30-35 years and require minimal maintenance. These frames cost £20,000 to £50,000. Maintenance costs £50 per year. Available in any RAL color. These frames offer better security and slimmer profiles.

Hardwood frames, impacting the modern conservatory cost significantly, range from £25,000 to £70,000. With proper care, they can last 50-60 years. Maintenance costs around £200 per year. While oak and mahogany are more expensive than pine, these frames require regular treatment to guard against weather damage, further contributing to the modern conservatory cost.
Glass Options
- Standard double glass comes with the base price. It provides basic insulation with a U-value of 1.6.
- Sun control glass adds £1,000 to £3,000. It blocks 75% of solar heat. This glass reduces air conditioning costs by 25%.
- Self-cleaning glass costs an extra £2,000 to £4,000. It needs cleaning twice per year instead of monthly. The coating lasts 25 years.
Roof Styles
- Glass roofs cost £3,000 to £8,000. They let in 90% of natural light. These roofs need cleaning four times per year.
- Solid roofs cost £4,000 to £10,000. They provide better insulation. These roofs reduce heat loss by 40%.
- Mixed roofs cost £5,000 to £12,000. They combine the benefits of both styles. These roofs offer the best temperature control.
Extra Costs
Planning fees and groundwork add 20-30% to base prices, significantly impacting the modern conservatory cost. Installation and labor costs vary by region and complexity. Additional features increase functionality but also raise the total cost of a modern conservatory.
Planning and Building Rules
Planning permission costs £200 to £500. Applications take 8-10 weeks. Building approval costs £300 to £800. Professional drawings cost £500 to £1,500. According to the UK Planning Portal, most conservatories need both permissions and specific sizing requirements apply.
Ground Work
Basic foundations cost around £1,500 and go down 1 meter, affecting the modern conservatory cost. Complex foundations can cost up to £6,000 and need to go down 2-3 meters. The type of soil also influences the price; for instance, clay soil requires deeper foundations, further impacting the modern conservatory cost.
Heating and Cooling
The Chartered Institute of Building Services Engineers provides standard pricing for conservatory heating systems. Floor heating costs £1,000 to £3,000. It heats spaces up to 20m². Air conditioning costs £1,500 to £3,500. It cools spaces up to 30m². Each radiator costs £400 to £800. Most conservatories need two radiators.
