What Affects the Cost?

Several key factors influence conservatory costs in Greenwich. The size and style (lean-to, Victorian, Edwardian, or gable-end) significantly impact pricing, with larger and more ornate designs commanding premium rates. Material choice—including timber, aluminium, or uPVC frames—affects both durability and cost. Planning permission and building regulation approvals add time and expense, particularly in conservation areas common across Greenwich. Quality of glazing (single, double, or thermally efficient glass), roof type (polycarbonate versus solid), and foundation preparation also influence the final price. Labour costs in Greater London are 25-35% above national averages.

Money-Saving Tips

Obtain quotes from 3–4 local builders to compare pricing and services. Choose a simpler design like a lean-to over more ornate styles to reduce costs. Consider phasing the project—install a basic structure first, then upgrade the roof or insulation later. Plan work for winter months when builders may offer discounted rates due to lower demand.

Frequently Asked Questions

Do I need planning permission for a conservatory in Greenwich?

Most conservatories under 3 metres high and extending less than 3 metres from the house are permitted development and don't require planning permission. However, Greenwich has conservation areas and listed buildings where stricter rules apply. Always check with your local authority or ask your builder to verify before starting work. Building regulations approval is always required.

What's the typical build time for a conservatory in Greenwich?

A standard lean-to or Victorian conservatory typically takes 6–12 weeks from start to finish, depending on site conditions, weather, and whether planning permission is needed. Larger or more complex designs can take 12–16 weeks. Weather and local authority processing times can add delays, particularly in winter.

Why are Greenwich conservatory prices higher than other areas?

Greater London labour costs are significantly higher than the national average due to demand, local living costs, and skilled tradesperson availability. Greenwich also has many period properties and conservation areas, which may require specialist work and materials. Additionally, ground conditions and building density can add complexity and expense compared to rural areas.

What warranty or guarantees do conservatory builders offer?

Reputable builders typically offer 1–2 years' warranty on labour and defects, plus 10-year FENSA or building regulation certification. Structural elements like frames often carry 10–12-year guarantees from manufacturers. Always request written warranty documentation and confirm that your builder is insured and registered with relevant trade bodies.
