Can i use my conservatory all year round?

Modern conservatories, with insulated bases and cavity walls which feature energy efficient double-glazed units and a thermally efficient conservatory roof, can be used all year round, with the sensible use of relevant heating.

Do we need planning permission or building regulation approval?

Planning Permission

Under the regulations that came into effect on 1st October 2008, adding a conservatory to your home is considered to be permitted development and does not need an application for planning permission, subject to the following conditions:

  • No more than half the area of land around the original house* would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation fronting a highway.
  • No extension to be higher than the highest part of the roof.
  • Maximum depth of a single-storey rear extension of three metres for an attached house and four metres for a detached house.
  • Maximum height of a single-storey rear extension of four metres.
  • Maximum depth of a rear extension of more than one storey of three metres including ground floor.
  • Maximum eaves height of an extension within two metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension no higher than existing house.
  • Side extensions to be single-storey with maximum height of four metres and width no more than half that of the original house.
  • Roof pitch of extensions higher than one storey to match existing house.
  • No verandas, balconies or raised platforms.
  • On designated land** no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions.

Where work is proposed to a listed building, listed building consent may be required.

*The term “original house” means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

**Designated land includes National Parks, the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites

Building Regulations

Building regulations will generally apply if you want to build an extension to your home. Though, conservatories are generally exempt when they meet a number of conditions.

  • They are built at ground level and are less than 30 square metres in floor area
  • At least half of the new wall and three quarters of the roof is either glazed or translucent material
  • The conservatory is separated from the house by external quality door(s)
  • Glazing and any fixed electrical installations comply with the applicable building regulations requirements
  • You are advised not to construct conservatories where they will restrict ladder access to windows serving rooms in roof or loft conversions, particularly if any of the windows are intended to help escape or rescue if there is a fire.
  • Any new structural opening between the conservatory and the existing house will require building regulations approval, even if the conservatory itself is an exempt structure.

Can conservatories be made private?

Conservatories can be made private with the use of obscure glass, solid panels, blinds or solid walls.

Do we need to install insulating double glazed units?

On April 1st 2002, the Government introduced Part L, amending the Building Regulations for the first time, to require replacement windows and doors to meet tough new thermal performance standards.

This doesn’t apply to conservatories that have a lockable external door separating the two rooms, such a door, French door or Patio door.

But Spectrum Glazing Ltd install insulated double glazed units as standard to improve th confort and thermal efficency of their conservatory installations.

Do you make conservatories to order?

Yes, all of our conservatories are tailor-made to your unique specifications; you pick the style, the size, the amount of openings and how many doors you require.

How long will it take to build our conservatory?

The average turnaround is 6 to 10 working weeks from signing the contract however, you need to be aware that at busier times of year, the process can take longer. Conservatories that need planning permission will take considerably longer but we can advise you further at your consultation with us.

We have an odd shaped space and or sloping garden - can we still have a conservatory?

It’s always best to get advice in these situations. In most cases, we are still able to come up with a solution for you but we are unable to answer this without seeing the site in person.

My builder has already constructed the base - what is the next step?

Contact us to come out and have a look. We will ensure that it is level and we can also come up with some design options for you.

What type of conservatories can you supply?

Since all conservatories are made to order, you can have anything that is physically achievable. A chat with our specialist conservatory designer will open up possibilities that you may never even have thought of.

Do we have to have tie bars?

Ultraframes conservatory tie bar replacement kit has eliminated many requirements for tie bars on certain size conservatories. There are some exceptions so we cannot give a blanket response as all rooms are made to measure and have their own unique set of specifications.

How do i know that i am buying good quality products?

Postcode checked for perfect weather proofing, the specially proven weather seals, rain baffle in ridge system, secondary drainage in glazing all combine to make this impervious to water penetration.

Do you do supply only conservatories?

Yes, we can offer diy conservatories on a supply only basis. We also offer supply and installation and are more than prepared to work with outside building companies who would be building the base for you. Contact us for more information.

Can i use my own builder?

Yes, we are more than happy to project manage around other tradesman. We are able to provide your builder with base plans and then we would prefer to come back and survey the base before commencing manufacture of the final products to ensure the base is square and level. It is better to do this than to risk manufacturing to the base plan alone.

Do i have to have a dwarf walls?

You can have dwarf wall any height that you wish. The more popular height is 600mm or 2ft; at this height you maintain good visibility to your surrounding area. If you opt for a lower wall, you will have better visibility and light, but if privacy is a priority for you, then could opt for a higher wall instead. If you were looking to use the room as a dining room, a higher wall may be preferred.
