How we compare

Where every number on this site comes from, and how to read it.

Prices

Price ranges are typical installed prices for the UK in 2026. Every figure starts from a named, dated source: national price guides, installer price pages and manufacturer information. Where a 2026 source publishes a price for a roof type, style and size, we use it. Otherwise we take the 2026 lean-to price for that roof and size (the average of the current sources, interpolated by floor area: small about 9m², medium 14m², large 20m²) and apply a style factor averaged from the premiums sources publish for Victorian, Edwardian, gable, P-shape and T-shape roofs. Older guides from 2023 to 2024 are kept only as cross-checks, and single-brand prices are used on brand pages, not in the general ranges. Most guides do not say whether VAT is included; installers usually quote residential work but always check.

The headline range for each roof is a medium conservatory across the four most common shapes (lean-to, Edwardian, Victorian and gable).

A price range is not a quote. Your price depends on the survey, the system and the installer.

The heat chart

No independent study has measured indoor temperatures under each type of conservatory roof, so we do not publish modelled room temperatures. Instead the chart shows two figures makers publish for every roof:

  • Heat lost in winter: the U-value in W/m²K. It is the rate heat escapes through each square metre for every degree of difference between inside and out. Lower is warmer.
  • Sun's heat let in: the g-value or total solar transmission, the share of the sun's energy that passes into the room. Lower is cooler on a sunny day.

Old glass is Ultraframe's standard double glazed unit (U 2.8, g 75%). Polycarbonate is 25mm to 35mm sheet (U 1.3 to 1.7, solar 8% to 63% from Solarguard to clear). Glass is performance glass (U 1.0 to 1.2, g 18% to 70% by tint and grade). Insulated panels use the centre of panel figure of 0.29 published by panel makers, with glazing bars adding to it. Solid tiled roofs use makers' published U-values of 0.12 to 0.18. Hybrid and orangery figures are our estimates from their typical solid and glazed areas and are labelled as such.

Old glass roofStandard double glazing, the typical before
Tiled roofUsing the room every month of the year
Glass roofKeeping the light and the view of the sky
New polycarbonate roofThe lowest cost fix for a leaking roof
Hybrid roofWarmth with pools of daylight
Insulated roof panelsA warmer room on a tighter budget
Orangery conversionA full extension feel without building a new room
Shorter bars on both sides mean a steadier room. Solid bar is the best published figure, pale bar the range across grades and tints. U-value in W/m²K; solar is the g-value or solar transmission. Figures from maker data (Ultraframe, Thermotec and others); hybrid and orangery are estimated from their solid and glazed areas. How we built this.

Scores

The scorecard rates each option out of five on summer comfort (solar heat let in), winter warmth (U-value), quiet in rain (roof mass and insulation, from maker and installer descriptions), daylight and value for money (typical price against the other four). They are editorial judgements built on the figures above, applied the same way to every option. No manufacturer or installer pays for a score.

Local pages

Town pages use only public datasets, each shown with its source on the page:

  • Towns and populations: ONS built-up areas and Census 2021, NRS and NISRA settlements, geocoded through postcodes.io.
  • Climate: Met Office regional climate series, 1991 to 2020 monthly averages.
  • Homes by age and type: VOA Council Tax stock of properties (England and Wales).
  • House prices: HM Land Registry UK House Price Index.

We do not publish installer counts, waiting times or reviews for a town unless we hold real data for it.
