A tiled conservatory roof replacement in London typically costs £7,000 to £18,000, depending on the size of your conservatory, the tile system you choose, and whether the existing frame needs reinforcing. London labour rates generally run 20–30% higher than the UK average, so a job that costs £6,000 in most of the country often lands closer to £8,000–£9,000 here for a like-for-like size. Jade Roofing Experts provides a free, no-obligation survey and a written fixed-price quote before any work starts — no hidden congestion charges, no surprise extras.
If you’re tired of your conservatory being unusable for half the year — too cold in winter, a greenhouse in summer — replacing the roof with a tiled, solid system is one of the most effective upgrades you can make. Below, we break down exactly what drives the cost, what to expect in North West and Central London specifically, and what questions to ask before you book any installer.

Tiled Conservatory Roof Cost in London by Size (2026)
These figures are based on current London labour and material costs for a standard polycarbonate-to-tile conversion, including scaffolding, disposal of the old roof, and Building Regulations application. Every quote we provide is fixed in writing after a free survey — these ranges are a starting guide, not a substitute for an inspection.
| Conservatory Size | Typical London Price Range |
|---|---|
| Small lean-to (approx. 3m × 3m) | £7,000 – £9,500 |
| Medium lean-to / Victorian (approx. 4m × 3m) | £9,500 – £13,000 |
| Large Victorian / Edwardian / P-shaped (approx. 5m × 4m+) | £13,000 – £18,000+ |
Prices assume no major structural reinforcement is needed. If your existing frame can’t support the additional weight of a tiled roof, add roughly £3,000–£4,000 for reinforcement work — this is common in older Victorian terraces across Camden, Islington and Kensington, where original frames were built for lightweight glass or polycarbonate only.
What Affects the Cost of a Tiled Conservatory Roof in London?
1. Roof size and shape
A simple lean-to is the most straightforward and least expensive shape to re-roof. Victorian, Edwardian, P-shaped and gable-end conservatories — common across the period properties we work on throughout Camden, Islington and Kensington — involve more complex rooflines, more cutting, and more time on site, which increases labour cost.
2. Tile system
Most London homeowners choose a lightweight tile system such as SupaLite, Ultraroof or Equinox rather than traditional clay or concrete tiles, which are too heavy for most conservatory frames without major reinforcement. Lightweight slate-effect tiles are the most popular choice we install — they’re BBA-approved, durable, and visually close to a natural slate roof at a fraction of the weight.
3. Structural reinforcement
Many conservatories built in the 1990s and 2000s in London were designed around a lightweight polycarbonate or glass roof. Upgrading to a solid tiled roof sometimes means strengthening the existing wall plates or frame first. We check this during your free survey, before any price is fixed — never after work has started.
4. Insulation specification
A tiled roof replacement is also your opportunity to significantly improve insulation. Higher-spec insulation costs more upfront but reduces heating bills and makes the room usable in winter — for many London customers, this is the entire point of the upgrade.
5. Building Regulations
Converting a conservatory roof from polycarbonate or glass to a solid tiled system in the UK usually requires Building Regulations approval, because the change affects the room’s thermal performance and structural classification. We handle the full Building Regulations application on your behalf, including any council paperwork — this is included in our fixed quote, not charged as a separate extra.
6. London labour rates
Skilled roofing labour costs more in London than in most of the UK — generally 20–30% above the national average — which is reflected in every legitimate quote you receive locally. Be cautious of quotes that look significantly cheaper than the ranges above; they often exclude scaffolding, waste disposal, or Building Regulations fees, which then appear later as “extras.”
Tiled vs Glass vs Polycarbonate: How Does Cost Compare?
| Roof Type | Typical Cost (London) | Best For |
|---|---|---|
| Polycarbonate | £4,000 – £7,000 | Budget-conscious; least insulating option |
| Glass | £6,500 – £12,000 | Bright, modern look; better insulation than polycarbonate |
| Tiled / solid | £7,000 – £18,000 | Best year-round comfort, insulation and resale appeal |
A tiled roof costs more upfront than polycarbonate or glass, but it’s the only option that effectively turns your conservatory into a usable, year-round room rather than a seasonal space — which is why it’s the upgrade we’re asked about most often.
Is a Tiled Conservatory Roof Worth It?
For most London homeowners, yes — particularly if your conservatory currently sits unused for half the year. A well-fitted tiled roof:
- Significantly improves insulation, cutting reliance on portable heaters in winter and reducing solar heat gain in summer
- Reduces noise from rain — a common complaint with polycarbonate roofs
- Adds a more permanent, higher-value look that blends with the rest of the property — particularly important on period terraces in Camden, Kensington and Islington
- Can make the room usable as a genuine home office, dining room or playroom rather than an occasional-use space
The trade-off is upfront cost and a small reduction in natural light compared to glass — though most homeowners offset this with a roof window or glass rooflight panel during the same installation.
Do You Need Planning Permission or Building Regulations Approval in London?
In most cases, planning permission is not required to replace a conservatory roof, provided the footprint, height and overall structure stay the same as before. Building Regulations approval is usually required, however, because converting from a lightweight roof to a solid tiled system changes the room’s insulation and structural classification.
In London conservation areas — which cover parts of Camden, Islington, Kensington and Westminster — there can be additional considerations around external appearance, particularly on listed or locally listed properties. We handle all the necessary applications and paperwork as part of every quote, so you’re not left navigating council requirements on your own.
How Long Does a Conservatory Roof Replacement Take?
Most tiled conservatory roof replacements in London take 3 to 5 days, depending on size and whether structural reinforcement is required. A simple lean-to without reinforcement can sometimes be completed in 2–3 days; larger or more complex roofs with reinforcement work typically take closer to a week.

Frequently Asked Questions — Tiled Conservatory Roof Cost London
► How much does a tiled conservatory roof cost in London?
A tiled conservatory roof replacement in London typically costs between £7,000 and £18,000, depending on the size of your conservatory, the tile system chosen, and whether structural reinforcement is needed. London labour rates generally run 20–30% above the UK average.
► Is it worth replacing a conservatory roof with a tiled one?
For most homeowners, yes — a tiled roof significantly improves insulation, reduces noise, and turns a seasonal space into a usable, year-round room. The main trade-offs are upfront cost and a modest reduction in natural light compared with a glass roof.
► Do I need planning permission to replace a conservatory roof in London?
Usually not, provided the footprint, height and structure stay the same as your existing conservatory. Conservation areas in parts of Camden, Islington, Kensington and Westminster may have additional considerations around external appearance.
► Do I need Building Regulations approval for a tiled conservatory roof?
Yes, in most cases. Converting from a lightweight polycarbonate or glass roof to a solid tiled system changes the room’s insulation and structural classification, which falls under Building Regulations. We manage this application for you as part of every project.
► How long does a conservatory roof replacement take?
Most projects take 3 to 5 days, depending on size and whether the existing frame needs reinforcing before the new roof is fitted.
► Can any conservatory take a tiled roof, or does it need reinforcing?
Not always — some conservatories, particularly those built in the 1990s and 2000s with lightweight frames, need additional reinforcement before they can support a solid tiled roof. We check this during your free survey before any price is fixed.
► What’s the cheapest way to replace a conservatory roof?
Polycarbonate is the lowest-cost option, typically £4,000–£7,000 in London, but offers the least insulation and the shortest lifespan. If budget is the main concern but you still want better performance than polycarbonate, a glass roof is a middle-ground option.
► Does a tiled conservatory roof reduce energy bills?
Yes — improved insulation reduces the need for supplementary heating in winter and limits heat build-up in summer, which typically lowers energy use associated with the room.
► Will a tiled roof make my conservatory darker?
Slightly, compared to a fully glazed roof — but most homeowners offset this by adding one or more roof windows or glass rooflight panels during installation, which we can include in your fixed quote.
► Does a conservatory roof replacement add value to a London property?
A well-finished, properly insulated conservatory that functions as genuine year-round living space is generally more appealing to buyers than a seasonal, single-glazed-feeling room — though the exact value impact depends on your property and local market.
