Conservatory planning permission for Kent homeowners

As part of the design process, we'll send out an experienced surveyor who will confirm whether you'll need planning permissions. If it is required, we'll take care of the process for you!

For the majority of conservatory installations, planning permission isn't needed. As of 1st June 2019, regulations in England are now more complaisant for single story extensions. This allows Kent homeowners greater flexibility to improve their home, rather than move.

However, some properties in conservation areas or who have already reached maximum allowances may be restricted by permissions. Our expert team will be able to advise on the best solution for you if this is the case.

If you are looking for conservatories in Maidstone or anywhere else in Kent we have you covered.

Conservatory Planning Permission

A comfortable temperature all year round

With our advanced materials, including modern uPVC and aluminium, you can be sure that your conservatory will offer exceptional energy efficiency capabilities. With their innovative designs, they'll efficiently keep the warmth inside of the room without letting the cold air in. Our conservatory glazing panels are chemically treated to improve their thermal capabilities, alongside their bespoke argon-filled inter pane designs. This could even save you money on your heating bills!

Extending your living space with a conservatory that you can use all year round gives you the ability to have an amazing new dining room space with the dining table as the centrepiece and the outside as your surroundings.

Our conservatory roofs, including glass, tiled and solid roofs work in the same way. They'll retain the heat and keep the draughts out, improving your home's carbon footprint. Their durable designs work like your current home would, providing an optimal temperature all year round, no matter the weather outside.

How much will it cost to build a conservatory?

The cost of a conservatory build will depend on these key factors:

  • What material the conservatory is made of
  • How big the conservatory will be
  • What the land you will build on is like
  • The type of roof you will have
  • The type of Glazing used for the conservatory

These factors are the key to the price of your conservatory.

What is a conservatory used for?

A conservatory adds another room to the home and typically it can be used as a lounge, sunroom or play area. The mostly glass construction of a conservatory makes it a perfect place to unwind in the evenings.

How big can a conservatory be without planning permission?

Typically you can build a conservatory without planning permission. However, there are limits. As a general rule as long as it doesn't take up more than half of the garden and is not above one story tall, you can build without planning permission. It is always best to ask an expert or check with your local authority to double-check.
