Conservatory roof replacement cost UK 2026<\/h1>\n

Too hot in summer, freezing in winter? The four main UK roof replacement options (solid, warm, glass, polycarbonate) with 2026 prices and planning-permission notes.<\/p>\n<\/div><\/section>\n\n\n

\n\n

Millions of UK homes have conservatories, and most of them are underused because the roof doesn’t work. Polycarbonate roofs turn the room into a greenhouse in summer and a fridge in winter. Old glass roofs leak or condense. If you’ve been using yours as junk-storage when you’d rather use it as a living room, the roof is almost always the problem.<\/p>\n\n

Replacing the roof transforms the space at a fraction of the cost of a full extension. This guide explains the four main options, typical 2026 UK costs, and when each makes sense.<\/p>\n\n

Per m\u00b2 benchmarks: polycarbonate ~\u00a3280-\u00a3450; glass ~\u00a3500-\u00a3830; warm roof ~\u00a3720-\u00a31,060; tiled solid roof ~\u00a3830-\u00a31,220.<\/p>\n\n

Solid \/ tiled roof \u2014 best thermal, most expensive<\/h2>\n

Lightweight tile system replacing the transparent roof entirely. Interior ceiling plastered, making the conservatory feel like a real extension. U-value 0.15-0.18 W\/m\u00b2K \u2014 better than most external walls. Winter warmth excellent, summer heat gain eliminated.<\/p>\n

Downsides:<\/strong> the space loses the skylight feel. Usually triggers Building Regulations because the space becomes a “real” extension \u2014 council fees + structural sign-off typically \u00a3500-\u00a3900 additional.<\/p>\n

Best for:<\/strong> homeowners who want a year-round living room, don’t mind losing the skylight effect, have \u00a38,000+ budget.<\/p>\n\n

Warm roof \u2014 middle ground<\/h2>\n

Insulated roof panels with plaster ceiling inside. Not tiled exterior but significantly warmer than glass or polycarbonate. Exterior is GRP or insulated panel. Can include roof lights for partial skylight effect.<\/p>\n

U-value around 0.18-0.22 W\/m\u00b2K. Cheaper than solid by \u00a31,000-\u00a32,000. Increasingly popular middle choice.<\/p>\n

Best for:<\/strong> good thermal performance, some skylight retention, budget \u00a36,000-\u00a39,000.<\/p>\n\n

Glass replacement \u2014 keep the feel, add performance<\/h2>\n

Modern self-cleaning solar-control glass replaces the old roof. Insulating low-E double glazing cuts summer heat gain 40-60% and winter heat loss 30-40% vs old polycarbonate. Retains full skylight experience.<\/p>\n

U-value 1.2-1.4 W\/m\u00b2K \u2014 worse than solid\/warm but dramatically better than existing polycarbonate (2.8-3.5).<\/p>\n

Best for:<\/strong> you love the light and openness, want noticeable comfort improvement without full reroofing, budget \u00a34,500-\u00a37,500.<\/p>\n\n

Polycarbonate \u2014 cheapest, shortest-term fix<\/h2>\n

Like-for-like polycarbonate replacement. Fixes leaks and yellowed panels. Doesn’t meaningfully improve thermal performance. If budget is the constraint, consider saving for another year and doing the glass replacement instead.<\/p>\n

Best for:<\/strong> short-term ownership (moving within 2-3 years), strict budget.<\/p>\n\n
