What Affects Conservatory Costs?

The overall price isn’t just the frame – here’s what might tweak your budget:

• Location: Location significantly affects conservatory costs. In London or the South East, add 10–20%—city rates sting! Regional labour and material market conditions can lead to variations in pricing, with costs tending to be higher in major cities due to disparities in labour expenses and material costs. Elsewhere, regional prices might mean a cheaper build. Labour costs vary too.
• Foundations: Basic dwarf walls are standard, but tricky sites (slopes, clay) could add £1,000–£3,000 to the base cost—an extra expense to watch.
• Upgrades: Love underfloor heating (£1,500–£3,000), a glass roof (£1,000–£2,000), or a tiled roof (£2,000–£5,000) for superior insulation? These energy-efficient heating sources boost year-round comfort.
• Planning Permission & Building Regulations: Most under 30 sqm dodge it, but listed homes might need a £200–£500 permit – view more about planning here
• Extras: French doors (£500–£1,000), bi-fold doors (£2,000+), or air conditioning units (£1,000–£2,000) add flair with glazing options and roof material upgrades.

FAQs

How long does it take to build a conservatory?

Typically, a conservatory takes 4–8 weeks to build, depending on size, style, and site conditions. This includes foundation work (1–2 weeks), frame and glazing installation (1–2 weeks), and finishing touches like electrics or plastering (1–2 weeks). Custom designs or delays (weather, permits) might extend this to 10–12 weeks.

Can I use my conservatory all year round without upgrades?

Without upgrades like insulation, heating, or a solid roof, a basic conservatory with a polycarbonate or glass roof can get too hot in summer and too cold in winter. Adding double glazing and ventilation helps, but for true year-round use, consider underfloor heating or a solid tiled roof replacement for your conservatory for better temperature control.

Can you just replace a conservatory roof?

Replacing a conservatory roof with solid tiles is possible but requires checking if the structure can support the added weight and ensuring compliance with local building regulations. Lightweight tile options exist to simplify the process, though ventilation and lighting changes should also be considered.

Do I need to inform my neighbours before building a conservatory?

You don’t legally have to, but it’s wise to chat with them, especially if it’s near their boundary. Under Permitted Development rules, you can build without planning permission if it meets size limits (e.g., under 30 sqm), but neighbours can object if it blocks light or privacy.

Can I build a conservatory on a small property?

Yes! Lean-to styles are perfect for small spaces, starting at 2m x 2m (4 sqm) for tight gardens or terraces. You’ll need to stay within Permitted Development limits (e.g., no more than 50% of your land’s area) and ensure access for installation.

How do I maintain a conservatory?

Clean the glass and frames every 3–6 months with soapy water to prevent grime buildup. Check seals and gutters yearly to avoid leaks, and trim nearby plants to stop scratches or moss. uPVC needs little upkeep, but timber frames may require repainting or staining every 5–10 years.
