Polycarbonate Conservatory Roof Services, Sorted for Good

If your polycarbonate conservatory is too hot in summer, too cold in winter, or unusable whenever it rains, the roof is the problem. We fit our COMFIBOARD insulated panel system to the existing polycarbonate frame, with a fixed price agreed at the survey and an insurance backed guarantee on every job.

Why Polycarbonate Roofs Are So Uncomfortable

Polycarbonate is lightweight and cheap to put up, which is why it was used on so many conservatories built between the 1980s and early 2000s. But it does almost nothing to manage heat or keep out cold. The roof turns the conservatory into a greenhouse in summer and a cold room in winter, and the drumming during rain makes it impossible to use even when the temperature would otherwise be fine.

Local, Direct and Accountable

We are based on the South Coast and cover Sussex, Kent and Surrey. One of our team visits your home, surveys the polycarbonate roof, and gives you a firm price on the day. No call centre, no subcontracted fitters, the team that surveys your conservatory is the team that stands behind the work.

One System, Fitted to Your Existing Polycarbonate Frame

ComfiSpace uses a single insulated panel system, COMFIBOARD, on every conservatory we work on. There is no range of products and no different approach for different roof types. We fit the panels directly into your existing polycarbonate roof frame, which means no removal of the frame, no structural alteration, and no planning permission required in the vast majority of cases. Inside, your existing glazing bars stay exactly where they are. We are not covering them over or adding a false ceiling, the room keeps the same look with the same internal structure, it simply stops being uncomfortable. To see how the same system works across other roof shapes, see our lean-to conservatory page, our Victorian conservatory page, or our glass conservatory roof services page.

No structural work in the vast majority of cases. Survey first, fixed price on the day.

How We Upgrade a Polycarbonate Conservatory Roof

Every polycarbonate roof is different once we look at it closely. The age and condition of the frame, the weathering around the edges, and the state of the guttering all affect what the job actually involves, which is why we survey before we price. One of our team visits your home, looks at the roof properly, and gives you a firm price before we leave, backed by our promise to beat any genuine like for like written quote by 5%. There are no estimates sent by email days later and no price that changes when we turn up.

What to Expect When You Book With Us

A Real Survey, Not a Guess

We come to your home, look at the actual polycarbonate roof, the frame and the weathering, and base your price on what is really there rather than an estimate from a description.

A Price You Can Act on Straight Away

We give you a firm price at the survey, with a discount available if you decide to go ahead with us on the day. If you want to take more time, that is fine, the price we quote stands.

No Hidden Extras

The price we agree at the survey is the price you pay. No VAT to add and no surprise costs once work is underway.

Work Fitted Around You

We agree a fitting date that suits you and confirm timing in advance, so you know exactly when the team is arriving.

A Tidy Finish, Every Time

Our fitters work cleanly, clear away all materials, and leave the conservatory and the area around it exactly as they found it.

Backed by a Real Guarantee

Every job carries our CPA insurance backed guarantee plus our price promise to beat any genuine like for like written quote by at least 5%.

Free survey, fixed price on the day, no pressure to decide before we have been to see you.

Trusted, Accredited and Insurance Backed

Our COMFIBOARD system carries full manufacturer accreditation, and every installation is protected by a CPA insurance backed guarantee, a level of cover most local installers do not offer.

How Your Conservatory Feels Once the Roof Is Done

Polycarbonate makes the temperature swings as extreme as possible. Once the panels are fitted, the room settles into a steady, comfortable temperature that holds whatever the season. Most homeowners tell us it feels like a different room, not just a slightly improved one.

Usable in Summer

The panels stop the polycarbonate acting as a heat trap, so the room stays usable on warm days instead of becoming the hottest place in the house.

Conservatories Upgraded

Quiet When It Rains

Rain on a polycarbonate roof is one of the most common complaints we hear. After the upgrade, that noise is gone. The conservatory becomes usable whatever the weather.

Does Your Polycarbonate Conservatory Sound Like This?

If any of these are familiar, the polycarbonate roof is almost certainly the cause, and it can be fixed without touching the rest of the conservatory.

Polycarbonate Conservatory Roof Services, Common Questions

Straight answers about what is involved in upgrading a polycarbonate conservatory roof with ComfiSpace, and what it costs.

Why is my polycarbonate conservatory so uncomfortable even though the roof looks fine?

Polycarbonate has very little thermal resistance, which means it lets heat build up fast in summer and gives up heat quickly in winter. The roof can look perfectly intact, with no cracks or yellowing, and still leave the room impossible to use from April through October and cold from November through March. The problem is not the condition of the polycarbonate, it is what polycarbonate is made of and what it cannot do. Adding an insulated panel system to the existing roof changes how the room performs at the most basic level, not as a repair but as a proper thermal upgrade.

How much does a polycarbonate conservatory roof upgrade cost?

Every polycarbonate conservatory is different once we look at the frame condition, the weathering and the guttering, so we do not publish a fixed price online. What we can tell you is that our jobs start from £3,500, and we back that with a price promise to beat any genuine like for like written quote by at least 5%. The only way to get an accurate figure for your specific conservatory is a free, no obligation survey, where one of our team will look at the roof and give you a firm price before they leave.

Will you need to remove my existing polycarbonate roof or frame?

No, not in the vast majority of cases. Our COMFIBOARD panel system is fitted directly into the existing polycarbonate roof frame, so there is normally no need to strip out the frame, remove the polycarbonate, or touch any structural element of the conservatory. The work is done largely from inside, which keeps disruption to a minimum and avoids the mess and cost of a full structural job. If your frame has unusual weathering or age-related issues that change what is needed, we will tell you clearly at the free survey before any price is agreed.

Will the inside of my conservatory look different after the upgrade?

From the outside, no change at all. Inside, your existing glazing bars stay exactly where they are. We do not box them in, add a false ceiling, or cover them over. The room keeps the same internal structure it has now, and the existing look is preserved. What changes is the performance, the room stops swinging between too hot and too cold and starts holding a steady, comfortable temperature through every season. Most homeowners tell us the change in how the room feels is more dramatic than they expected, while the room itself still looks familiar.

Will fitting insulated panels reduce the light inside my conservatory?

Yes, and we always talk through this honestly at the survey. Fitting insulated panels over the polycarbonate means less light comes in through the roof. The room still receives light through all the side glazing, and many homeowners find the quality improves because the harsh overhead glare from the polycarbonate is gone and the light that remains comes in more evenly through the walls. We bring photographs of finished jobs to the survey so you can see exactly what to expect before you commit to anything. Most homeowners tell us the trade-off is well worth it once they have used the room through a full season.

Do I need planning permission to upgrade a polycarbonate conservatory roof?

In the vast majority of cases, no. Because we are upgrading the existing roof structure rather than altering the footprint, height, or shape of the conservatory, planning permission is not normally required for the work we carry out. Conservatories are generally treated as exempt structures in the UK, and an insulated roof upgrade fitted into the existing frame typically falls within that exemption comfortably. Every property is slightly different, particularly listed buildings or homes within conservation areas, so we will flag anything relevant to your specific situation at the free survey before any price is agreed or work is planned.

How long does a polycarbonate conservatory roof upgrade take?

Most standard polycarbonate conservatory roofs are completed in a single day, with the team arriving in the morning and the conservatory usable again the same evening. Larger conservatories, or those made up of more than one section, can take a little longer to do properly. We do not quote a generic timescale that may not apply to your home. At the free survey, we will give you a realistic estimate for your specific roof, based on its size, shape and the condition of the existing frame, so you can plan around it with confidence and know exactly what the day of fitting will involve.

What happens at the free survey?

One of our team comes to your home and looks at your polycarbonate roof properly, rather than estimating from photographs or a description over the phone. They check the frame, the weathering and the guttering, talk you through exactly what the work involves, and answer any questions you have on the day. Before they leave, they give you a firm price for the job, with our price promise to beat any like for like written quote by 5%. There is no obligation to go ahead at that point, and if you want more time to think it over, the price we give you stands.

Can you give me a price over the phone or by email?

Not accurately, no, and we would rather be straight about that than give you a number that turns out to be wrong. Two polycarbonate conservatories that look identical from a photo can need very different work once we are actually there, because the condition of the frame, the weathering around the edges, and the state of the guttering all affect what is involved. A job that looks straightforward from the outside can be more involved once we see it, and giving a price before we have done that would not be honest. We always survey first and give you a firm price on the day.

Do you cover polycarbonate conservatories across all of Sussex, Kent and Surrey?

Yes. We are based on the South Coast and cover Sussex, Kent and Surrey as our core working area, with free surveys available throughout the region. We keep our coverage deliberately local, so the team that surveys your conservatory knows the area, the typical building stock, and the kind of weathering and frame issues that come up in this part of the country. If you are unsure whether your postcode is within our area, get in touch and we will confirm straight away.
