Six Distinct Styles
Victorian, Edwardian, lean-to, gable-end, P-shape and orangery — each engineered to suit a specific era of home, elevation and use.
Warm Roof U-values of 1.0–1.4 W/m²K
Fully insulated tiled or hybrid warm roofs improve year-round thermal performance for conservatories across London and the Home Counties.
Solar-Control Glazing
Neutral- or blue-tint self-cleaning solar glass on the roof reduces summer heat gain by up to 78% while still delivering an A-rated whole-window U-value.
Underfloor Heating & Cooling
Integrated wet or electric UFH runs from your existing boiler or a heat pump; optional trickle ventilation and openable roof vents keep it usable in July as well as January.

Design, structural calcs, foundations, dwarf walls, glazing, electrics, plastering and decoration under one roof — one contract, one named surveyor, one aftercare number.
What Kensington homeowners tell us.
"The sliding sashes are indistinguishable from the originals — the conservation officer signed off first time. Immaculate site management too."
"Four quotes, one honest conversation. Their surveyor spent two hours explaining trade-offs — no other firm came close on either detail or clarity."
"Nine windows swapped across a Victorian first-floor flat. Zero mess, done in three days, and the acoustic laminate has genuinely changed how we sleep."

- How long does conservatories installation take in Kensington?

- Do you handle conservation-area planning in Kensington?
- Working across London means understanding period detail, party-wall etiquette and permit parking as well as we understand glass. We schedule dust sheets, protection and clean-down like a good building firm should. We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Kensington projects that require them.
- What guarantee covers conservatories in Kensington?
- Every conservatories installation in Kensington is covered by our insurance-backed 10-year guarantee — parts, labour and finish. Aftercare is direct with the installing team, not a call centre.
- Can I see recent conservatories work near Kensington?
- Yes — we can share recent conservatories case studies from across London, including projects in Notting Hill, Holland Park and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does conservatories achieve in Kensington?
- Tiled and hybrid warm-roof conservatories across Kensington, London achieve roof U-values of 1.0–1.4 W/m²K for improved year-round thermal performance.
- Do I need planning permission for a conservatory?
- Most conservatories fall under permitted development — a rear single-storey addition up to 3m (semi/terraced) or 4m (detached), under 4m tall, and not covering more than 50% of the original garden. We assess this at survey and handle any lawful development or full planning application on your behalf.
- What U-value does a tiled or hybrid conservatory warm roof achieve?
- Our tiled and hybrid warm roofs achieve roof U-values of 1.0–1.4 W/m²K. Combined with energy-efficient glazing and a surveyed heating and ventilation plan, they improve year-round comfort across London and Home Counties conservatories.
- Do conservatories need Building Regulations approval?
- Not usually — a conservatory separated from the house by external-quality doors (i.e. French, patio or bifold), with independent heating controls, is normally exempt. An orangery with an open connection to the house does require Building Regs and we handle the submission.
