We’ve compared the three biggest branded systems – SupaLite, Guardian, and Ultraframe Ultraroof – plus market rate data from independent installers to break down exactly what a tiled roof conversion costs. All prices are verified as of April 2026 and include installation.
- A tiled roof on a 4x4m conservatory costs £8,000-£12,000 - this includes the roof structure, tiles, insulation, internal plastering, and Building Regulations sign-off
- SupaLite is the only brand to publish prices from £10,000 + VAT for 10m2 - Guardian, Ultraframe, and WARMroof are quote-only, making direct comparison harder
- All major systems achieve a U-value of 0.15 W/m2K - that is 6 times more insulating than polycarbonate (1.0-1.5) and turns your conservatory into a usable room year-round
- Building Regulations approval is mandatory for solid roof conversions - branded systems include this in the price, saving you the £250-£400 separate application cost
- A solid roof can add 5-10% to your conservatory’s property value contribution - estate agents value solid-roof conservatories as genuine living space rather than a seasonal add-on
Tiled Conservatory Roof Costs by Size
Conservatory size is the single biggest cost factor. It accounts for roughly 50% of price variation. Larger conservatories cost more in total but less per square metre. Installers spread fixed costs like scaffolding, building control, and waste removal across a bigger project.
| Conservatory Size | Roof Area (approx.) | Cost Range | Cost Per m2 |
|---|---|---|---|
| Small lean-to (3x3m) | 9-10m2 | £6,100-£8,500 | £680-£850 |
| Medium Edwardian (4x3m) | 12-14m2 | £7,500-£10,500 | £625-£750 |
| Standard Victorian (4x4m) | 16-18m2 | £8,000-£12,000 | £500-£670 |
| Large P-shape (6x4m) | 24-28m2 | £11,000-£15,000 | £460-£535 |
Prices include materials, labour, insulation, internal plasterboard, and building control. Optional extras are not included. LED downlights cost from £300, VELUX roof windows from £800, and internal redecoration from £300.
Victorian conservatories with hipped roofs cost 10-20% more than lean-to or Edwardian styles. The angled sections need more tile cuts and ridge detailing. P-shaped and L-shaped designs are the most expensive due to extra valleys and complex geometry.
SupaLite vs Guardian vs Ultraframe: Price Comparison
Three brands dominate the UK tiled conservatory roof market. All achieve similar thermal performance. They differ in pricing transparency, warranty terms, and installer networks. Here is how they compare on the factors that matter.
| Feature | SupaLite | Guardian | Ultraframe Ultraroof |
|---|---|---|---|
| Published Price | From £10,000 + VAT (10m2) | Quote only | Quote only |
| U-Value | 0.15 (0.12 enhanced) | 0.15 | 0.15 (0.12 option) |
| Install Time | 3 days typical | 3-4 days | 1-3 days (watertight in 6 hours) |
| Warranty | Not published | 10yr product + 10yr workmanship | 10 years |
| Building Regs | Included | LABC/LABSS partner (included) | Included |
| Roof Window Option | Available | VELUX partnership (exclusive) | Available |
| Key USP | ExtraLight tiles, price transparency | VELUX integration, 20yr warranty | Widest span (4m, no tie bar) |
| Trustpilot | No reviews | 2.6/5 (12 reviews)* | 4.4/5 (106 reviews) |
*Guardian’s Trustpilot score reflects the manufacturer, not individual installers. Ultraframe’s higher rating benefits from a larger sample size and covers the brand as a whole.
For a deeper head-to-head comparison of SupaLite and Guardian specifically, including installer networks and build quality differences, see our dedicated SupaLite vs Guardian comparison.
Our take: SupaLite gets credit for publishing prices upfront. Ultraframe has the strongest track record and fastest installation. Guardian’s VELUX partnership is useful if you want sky views from a solid roof. Get quotes from all three and compare total installed cost, not just the roof price.
What’s Included in a Tiled Roof Quote?
A tiled roof installation involves stripping the old roof, fitting a new frame, adding insulation and tiles, then finishing the interior. Knowing what should be included helps you compare quotes and avoid hidden extras.
A standard tiled roof quote should include all of the following:
| Item | Included? | Typical Cost if Separate |
|---|---|---|
| Roof structure (aluminium or timber frame) | Yes | N/A |
| Tiles (lightweight concrete or composite) | Yes | N/A |
| Insulation (minimum 0.15 U-value) | Yes | N/A |
| Internal plasterboard and skim | Yes (most brands) | £500-£1,200 |
| Building Regulations approval | Yes (branded systems) | £250-£400 |
| Waste removal (old roof) | Usually yes | £120-£300 |
| Scaffolding | Sometimes | £400-£800 |
| LED downlights | No (optional extra) | £300-£600 |
| Roof windows (VELUX or similar) | No (optional extra) | £800-£2,000 |
| Internal redecoration | No | £300-£800 |
Always ask whether plastering, scaffolding, and building control are included. These three items can add up to £2,400 if listed as extras rather than included in the headline price.
Worked Example: 4x4m Victorian Conservatory
Here is a realistic cost breakdown for the most common project. This covers a 4x4m Victorian conservatory converting from polycarbonate to a tiled solid roof. We have used SupaLite pricing as a baseline since they are the only brand that publishes costs.
| Cost Element | Amount |
|---|---|
| SupaLite roof system (approx. 17m2) | £8,500 |
| Installation labour (2-person team, 3 days) | Included |
| Building Regulations (LABC) | Included |
| Internal plasterboard and skim | Included |
| Waste removal | Included |
| Scaffolding | £500 |
| LED downlights (6 spots) | £450 |
| 1 x VELUX roof window | £1,200 |
| Total (ex. VAT) | £10,650 |
| Total (inc. 20% VAT) | £12,780 |
Without extras, the base cost is around £9,000 including VAT. Most homeowners add at least downlights. The solid roof blocks the natural light your old polycarbonate or glass roof used to provide.

Building Regulations for Tiled Conservatory Roofs
Replacing a lightweight roof with a solid tiled roof always requires Building Regulations approval. This is non-negotiable. A solid roof changes the structural loading on the frame and foundations. You need an approved inspector to confirm the structure is safe.
What Building Regulations cover: structural integrity (can the existing frame support the heavier roof?), thermal performance (U-value must meet current standards), fire safety, ventilation, and electrical work (if adding downlights).
How branded systems handle it: SupaLite, Guardian, Ultraframe, and WARMroof all partner with LABC (Local Authority Building Control). Their approved installers submit the application as part of the installation. You receive a completion certificate once the work passes inspection. This is included in the price.
What happens if you skip it: Without a completion certificate, you could face problems selling your home. Mortgage lenders check for certificates on structural work. Retrospective approval costs more and may need invasive inspections. Always insist on the certificate.
You generally do not need planning permission for a tiled roof conversion. This applies as long as you are not changing the footprint, height, or position. Exceptions apply for listed buildings and conservation areas. For full pricing and alternatives, see our conservatory roof replacement cost guide.
Pros and Cons of a Tiled Conservatory Roof
A tiled roof is a significant investment compared to replacing like-for-like with polycarbonate or glass. It makes sense for homeowners who want year-round use, but it is not the right choice for everyone.
Want insulation without losing all natural light? A hybrid roof (solid panels with glazed sections) costs £5,500-£13,500. See our conservatory roof replacement cost guide for details. For help finding installers, see our best conservatory companies guide.
Regional Cost Variations and Lead Times
Tiled conservatory roof prices vary across the UK by 15–25%. London and the South East run 10–15% above the national average; Scotland, Wales, and the North East run 5–10% below. Lead times also differ by region, driven by manufacturer freight distances and local installer demand.
- London & South East: £10,500–£14,500 fitted, 6–8 week lead time. See our best conservatory roof companies London guide for installer shortlist.
- Manchester & North West: £8,500–£11,500 fitted, 5–7 weeks. SupaLite proximity (Chorley manufacturing) gives a price advantage. See our Manchester installer guide.
- Glasgow & West Scotland: £7,500–£10,000 fitted, 6–8 weeks. See our Glasgow installer guide.
- Cost drivers: Labour rates account for around 60% of the regional variance. Material costs are similar nationally; installer overheads (parking, ULEZ, congestion) drive the rest.
