Is Your Conservatory a Fridge in Winter and an Oven in Summer?

Warmer Winters

Insulated lining locks heat in and eliminates cold draughts — use your conservatory 12 months a year.

Cooler Summers

Reflects solar heat before it builds up inside. Stay comfortable on even the hottest days.

Quieter Space

No more rain drumming on polycarbonate. Platinum Seal dramatically reduces noise.

Sleek Finish

Clean, modern tongue-and-groove panels. A professional finish that completely transforms the room.

Meet the Owner

I Started With a Van, a Set of Tools, and a Standard to Uphold.

I'm Craig Wilson — qualified carpenter, with additional qualifications in roofing and general building. I started out as a one-man band, going from job to job, fixing problems, doing it properly. Over the years I built a team, a reputation, and a system.

Platinum Seal came from a simple idea: there had to be a better, smarter, more affordable way to transform a conservatory. A technique that actually works — that makes your space warmer in winter, cooler in summer, looks great, and doesn't cost a fortune. So I developed one.

We're not here to rip people off. We're here to deliver a product that lasts, at a price that's fair, with a team that actually cares. Over 6,000 projects completed nationwide. Our reputation speaks for itself — and we're here for the foreseeable.

What's Inside

SuperQuilt Insulation — The World's Highest Performing Multi-Foil

Platinum Seal uses SuperQuilt — a 19-layer, 40mm multi-foil insulation blanket that is independently certified and recognised as the UK's highest performing insulation of its kind. BDA Kiwa certified, NHBC and LABC approved.

Like a mirror reflects light, SuperQuilt reflects heat — keeping warmth in during winter and excessive solar heat out during summer. It also acts as a vapour control layer, eliminating condensation issues that plague standard polycarbonate roofs.

Coverage

We Cover the Full of the UK — Nationwide

Platinum Seal operates across the entire United Kingdom. From Southampton to Scotland, from Wales to the East Midlands — wherever you are, we can come to you.

And because we can quote remotely — no site visit needed — distance is never a barrier. Send us your address and a few photos and we'll have your quote back fast, wherever you are in the country.

Integrated Spotlights

LED spotlights fitted flush into your new ceiling for a clean, premium finish.

Synthetic Slate Roof

Full external synthetic slate upgrade — transforms the kerb appeal of your conservatory entirely.

EPDM Flat Roof

Flat roof areas upgraded to fully bonded EPDM rubber. Watertight, guaranteed, long-lasting.

Bespoke Works

No two conservatories are the same. We assess and tailor exactly the right solution for your space.

Using advanced remote measurement technology, we can accurately measure your conservatory and provide a fully tailored quote — without stepping foot on your property.

Note: skylights can be retained in most conservatory types. We'll advise exactly what's possible for your specific roof during the quote.

We work nationwide — but if you'd prefer to meet Craig in person, we offer a full home survey. Craig will visit your property, assess your conservatory in detail, and provide a comprehensive tailored quote and recommendations on-site.

Available nationwide. The £199 survey fee is fully deducted from your final invoice when you go ahead with us.

DocuSign Contract

All work is agreed and signed via DocuSign. Your start date is confirmed on the contract — no vague promises, just clear commitments in writing.

5% Back for Every 3 Days Over

If we go over the agreed project duration, we give you 5% of the contract value back for every 3 days. We stay on your job until it's done. We don't pull off.

Dedicated WhatsApp Group

A private WhatsApp group is set up for every job. Daily process pictures, general communication throughout, and it stays open for your full warranty period.
