Why do prices vary by conservatory size?

Standard conservatories take between three to four weeks to install. Larger than standard conservatories can take up to a month and a half. They are major construction projects and any homeowner investing in one should expect it to take much longer than other home improvement projects they’ve done in the past. That’s because of the sheer volume of work required and the quality of workmanship needed to get the job just right.

What factors other than conservatory size affect the price?

The three major choices of conservatory frame are:

  • uPVC frames – The best option for homeowners on a budget. Very low maintenance, great insulating properties, and recent developments in technology mean that it’s better-looking and longer-lasting than ever before.
  • Aluminium frames – Very long-lasting, rust-resistant, and low maintenance. A wide range of personalisation options are available and they are currently very much in fashion, particularly on full-glazed side conservatories.
  • Wooden frames – Aesthetically beautiful and traditional, wooden frames undergo multiple treatment processes prior to being shaped for your conservatory to ward off future distortion or damage. Wooden frames require the highest level of maintenance out of the three options and are also the most expensive.

Conservatory roofs

Ask your installer for prices on the three most popular new conservatory roofing options:

  • Polycarbonate conservatory roof – The best choice for homeowners on a budget, it’s quick to install, it looks great, and there are a lot of options to choose from.
  • Double glazed conservatory roof – Great-looking and brilliant for insulation, the most popular choice for homeowners.
  • Tiled conservatory roof – The fastest growing conservatory roof type. Tiled conservatory roofs are better at insulating against swings in outside temperature and from noise pollution. You can also let a lot of light in by choosing the right number of roof lights to suit you.

Conservatory flooring

The five most popular options for conservatory flooring are:

  • Conservatory floor tiles – Very easy to clean and works really well with underfloor heating systems.
  • Wooden conservatory flooring – The classic floor covering add style and elegance to the interior of your conservatory but it comes at a price.
  • Laminate conservatory flooring – A cheaper alternative and offering a very close aesthetic approximation to wood.
  • Vinyl conservatory flooring – Very budget-friendly and provides additional warmth to your feet on colder days.
  • Carpets for your conservatory – A great budget option and very handy for its fall-cushioning qualities if you want your kids to use the conservatory.

Dwarf wall conservatory costs

Historically, conservatories had fully glazed walls because they were intended for use as superior forms of greenhouses. Obviously, people now want them for a very different reason and, as a result, it’s much more common for homeowners to have dwarf walls on their conservatories. A dwarf wall is a low wall that is used at the base for the perimeter of a conservatory and it usually stands about 1 metre high.

Dwarf walls can often add cost to conservatory installation, but many homeowners see this as a worthwhile investment that will see a return on their initial cost, here’s why:

  • The addition of a dwarf wall makes a significant difference to how warm your conservatory is during the summer. Solid walls are, naturally, better at insulating than glazing and so the conservatory will be warmer in winter and cooler in summer compared to a fully glazed conservatory.
  • A dwarf wall provides a strong and secure structure for the conservatory
  • Your installer will take care to match your conservatory’s brickwork to the brickwork on your home – many people feel that this makes their conservatory look far more like part of their home rather than full-glass sides.

Conservatory material costs

The larger your conservatory, the more materials will be needed to complete the build. Your installer will, more likely than not, be able to secure a discount on buying extra materials for your project – they may or may not pass some or all of these savings onto you.

Labour and sub-contractor charges for conservatories

Again, with larger conservatories, more labour and sub-contractor hours are needed during its construction. If your conservatory requires planning permission, or if you have very particular ideas about what you want your conservatory to look like, this will take additional time for the builders to complete.

Other factors that will affect your conservatory cost in addition to the size are:

  • The number of electrical sockets you require internally and externally
  • Light fittings both inside and outside
  • TV points (aerial, cable, and Sky)
  • Telephone and broadband points
  • Base wall and house wall plastering
  • Finishings (including skirting board, architraves, and so on)

Perhaps. If you don’t live in a listed building, in a Directive 4 area, or in a conservation area, you won’t need planning permission unless your conservatory stretches more than 3 metres past your back wall (four metres if you live in a detached property) and it’s not more than 4 feet high.

If in any doubt, speak to your installer about your plan and contact your local Planning Office for extra help.
