Can I Remove My Conservatory Doors?
It’s one of the most common questions we hear lately — “Can I remove the doors between my conservatory and my house to make it feel open-plan?”
As modern conservatory roofs have become better insulated and thermally efficient, many homeowners now see their conservatory as a natural extension of their home rather than a separate space. And with that comes the temptation to take out the doors entirely.
The good news is — yes, it’s often possible. But there are a few important things to understand first.
Why Those Doors Were There in the First Place
When most conservatories were built, Building Regulations required a thermal barrier — usually a set of doors — between the main house and the conservatory.
This barrier stopped too much heat escaping and allowed the conservatory to be classed as a separate structure rather than a formal extension.
Fast forward to today, and the insulation levels of modern solid roofs — such as the LEKA Warm Roof or 2Hot2Cold’s bespoke timber and fibreglass systems — can match, or even exceed, those of a standard house extension.
So naturally, homeowners want the same open, flowing feel.
That’s where Building Control comes in.
What Happens When the Doors Come Out
Removing that original thermal barrier changes how your home retains heat. To stay compliant, the structure must be assessed under current energy-efficiency standards — using a SAP calculation.
This isn’t something you need to worry about arranging.
As part of the process, 2Hot2Cold’ will liaise directly with your local Building Control office, arranging the required SAP assessment and ensuring everything is approved before work begins.
The important thing is to plan it from the start — not as an afterthought — so that everything is built to the correct specification from day one.
Why the Rest of the Conservatory Matters Too
Even with a highly efficient new roof, the rest of the structure plays a big part in your home’s overall performance.
The age of your window frames, the condition of your floor insulation, and the quality of your glazing all affect how comfortably the space performs once those doors are removed.
When we carry out your survey, our team will look at the entire conservatory — not just the roof. We’ll check for signs of ageing frames, gaps, or outdated glazing and, where appropriate, provide a quotation for replacements.
Many homeowners use this opportunity to modernise the look — switching to slimmer frames, adding anthracite grey or black finishes, or reconfiguring how windows and doors open to make the space brighter and more practical.
These updates often transform a once “add-on” conservatory into a fully integrated, year-round room.
The Risks of Skipping Building Control
It can be tempting to remove the doors without notifying Building Control, especially if the roof is being replaced anyway. But doing so could cause problems later — particularly if you sell your home.
Without certification, solicitors may flag the alteration as non-compliant, meaning you’ll need to pay for retrospective SAP calculations or even insulation upgrades to regularise the change.
By managing the process properly now, you’ll have full certification and long-term peace of mind.
