Stop writing off your conservatory every winter and summer. An insulated Platinum Seal roof means lower heating bills and a room you can use all year, fitted across Southampton, Portsmouth and Winchester in 1 to 3 days.
A conservatory roof is the biggest single heat leak in most houses. Insulate it and the room stops being storage space and starts being part of the home again. Until March 2027 the work is zero-rated, so there is no VAT to add.
Platinum Seal qualifies as an energy saving material under HMRC's Energy Saving Materials relief, so the entire job is currently zero-rated. It applies to polycarbonate and glass roofs alike, as long as the existing roof structure is retained.
Based on HMRC Energy Saving Materials VAT relief. Eligibility is subject to installation type, and we recommend confirming with your accountant.
A 40mm multi-foil blanket, sealed as a vapour barrier, keeps the heat in the room instead of letting it straight out through the roof. Less heat lost means less gas burned to keep the rest of the house warm.
No more closing the door on the conservatory in October and writing the room off until spring. With the ceiling insulated the room holds its heat, so it stays part of the house in December rather than a cold store for the garden furniture.
SuperQuilt reflects up to 97% of radiant heat, so the room stops behaving like a greenhouse the moment the sun comes round. Integrated spotlights and a tongue-and-groove finish make it read as a proper room, not a lean-to.
Book a free, no-obligation home visit and you will get a proper look at your conservatory, a straight answer on what it needs, and a fixed price in writing. No pushy sales, no obligation.

"Craig visited my property and immediately put my mind at ease. The quote was clear, detailed, and included different options, real confidence in the company.

"Craig was very professional in reviewing our roof, offering potential solutions and following up with the appropriate quotes. He was helpful and flexible at all times. It was quite a difficult job with complications along the way but the team sorted it. I would have no problem in recommending them to anyone."

Workmanship guarantee on every conservatory roof we fit
From your first enquiry to the finished job. Straightforward, no faff.
Tell us where you are and what your conservatory is like. Takes about a minute.
Craig or one of the team rings you back the same day and books your free home visit at a time that suits you.
We come to you, measure properly, talk through the options and leave you with a fixed per square metre price in writing, signed by DocuSign. Free, with no obligation to go ahead.
We book your date and our own team fits it, usually inside 1 to 3 days. You get a dedicated WhatsApp group for the job, a 10-year warranty, and 5% back for every three days if we overrun.
The pair below is one conservatory, photographed before we started and again on the day we finished. Under it, more of the 6000+ jobs completed across Southampton and Portsmouth.
Everything below is quoted at the same time as the insulation, so there is one price and one visit rather than a second job booked in later.
Fitted flush into the new ceiling while it is still open, so the wiring is hidden and there is no second visit to pay for. Four to eight depending on the span.
A full external slate finish over the insulated deck. From the garden it reads as a proper tiled roof rather than a conservatory, at a fraction of the weight of natural slate.
Where the conservatory meets the house there is often a flat section, and that is usually what leaks. Fully bonded EPDM goes down as one sheet with no seams to fail.
Altered, extended or non-standard conservatories assessed individually. Craig is carpentry, roofing and building qualified, so an awkward structure gets a straight answer rather than a no.
Platinum Seal is a product of Platinum Roofs & Building Ltd, a Southampton company with a team of 25 behind it. We know the local stock: the polycarbonate lean-tos on the estates out at Bitterne and Millbrook, and the big glass roofs towards Bassett. Fixed per square metre, fitted in one to three days.
The carpenters and roofers on your job are on our payroll, not agency labour booked in for the week. It is why the standard is the same on every install, and why there is someone to come back if you ever need us under the warranty.
The fixed per square metre price, the scope, the start date and the overrun term all go into a contract you sign by DocuSign before anything is booked. Nothing about your job rests on a verbal promise.
SuperQuilt is BDA Kiwa certified and NHBC and LABC approved. The specification stands up to a building inspector rather than relying on our word for it, and it carries its own manufacturer warranty on top of ours.
Public liability and employer's liability insurance is in place on every job, and we email the certificates across before work starts. We are a VAT registered limited company with a registered office in Southampton, and the registration numbers are in the footer if you want to check them.

Founder and time-served conservatory insulation upgrade specialist
“I started this business as a one man band in a van, doing every job myself from start to finish, with one rule: do it properly or don't do it at all. I run a team of 25 now, but the person running this company can still do every single job himself. That means the standard isn't a number on a sheet. It's personal.”
Based in Southampton, we cover Hampshire and West Sussex, plus the Dorset coast, from Poole and Bournemouth across to Chichester and Bognor Regis, and north to Basingstoke and Andover.
