Frequently asked questions

Affordability is perhaps the most important consideration for any homeowner. Conservatories vary greatly in price, starting at around £10,000 right up to over £100,000. Costs will be influenced by size, material, design, roof, glazing type, and site. It’s also worth visiting our vast show centre where we can give you guideline prices for models as displayed.

In short, most garden building installations do not require planning permission as they are deemed to be “permitted development” as long as you follow the very simple guidelines as listed in our guide for planning permission.

When you’re planning a conservatory installation, it’s important to have a realistic timescale. This can help to limit disruption to your daily routine. Of course, timescales will depend on the size and complexity of the installation. A free survey will give you a general idea of what timescale to expect.
