High Efficiency Doors UK – A-Rated Composite, UPVC & Timber-Aluminium
High Efficiency Doors help UK homeowners reduce heat loss, improve security, and enhance comfort with modern A-rated entrance solutions. LAMTANS Engineering supplies and installs energy-efficient composite, UPVC, and timber-aluminium doors from our Manchester base, delivering quality upgrades across the UK.
Why Upgrade to High Efficiency Doors?
Upgrade to high efficiency doors to reduce heat loss, lower bills, and improve security, comfort, and aesthetics across your home. A new A-rated door is one of the most visible and impactful home improvements you can make.
Keep warm air in and cold air out — high efficiency doors dramatically cut heat escaping through your entrance.
Save £50–£150 per year on energy bills. Part of a whole-home energy efficiency strategy.
No more cold air under the door. Modern threshold seals and compression gaskets seal every gap.
Modern doors feature 3–5 point multi-point locking as standard — significantly harder to force than older single-point locks.
A new door transforms the front of your home. Choose from a wide range of styles, colours, and glass options.
Warm door panels and thermally broken frames eliminate the cold surfaces that cause condensation and damp.
What Makes a Door “High Efficiency”?
High efficiency doors combine advanced design features to minimise heat loss, improve insulation, and enhance energy savings. We only install A-rated or above doors to ensure maximum performance for your property.
Types of Doors We Install
From period properties to modern builds, we offer composite, UPVC, and timber-aluminium doors — all A-rated or above. Our expert team helps you choose the right type for your property, budget, and style.
The practical choice for back doors and projects where cost matters. Modern UPVC doors are A-rated, low maintenance, and long-lasting.
The most popular choice for front doors — A+ rated, extremely secure, and available in hundreds of styles, colours, and glazing options.
The highest performing option — A++ rated, ideal for period properties and high-end builds where appearance and longevity are paramount.

Door Installation Process
Our clear six-step process guides you from initial survey to bespoke A-rated door installation and final handover — with minimal disruption and no surprises.
We measure your door opening, assess the existing frame, and discuss your requirements for style, glazing, and security. No charge — no obligation.
We provide a fixed, itemised price for your A-rated door. No hidden costs — everything is agreed before we start.
Your bespoke door is manufactured to your exact measurements and specification. Typical lead time is 2–4 weeks from order.
The old door is removed and the new door is fitted in a single day. We protect your home throughout and leave the area clean on completion.
All trims are fitted, the door is sealed, and all hardware is adjusted for a perfect fit. We test the locking mechanism and ensure smooth operation.
We hand over your Insurance Backed Guarantee documentation through QualityMark and BlueDrop, confirming your installation is fully covered. Guarantee duration confirmed in your quote documentation.
Do You Need Planning Permission for New Doors?
Most homeowners do not need planning permission for a new door. The main exceptions are conservation areas, listed buildings, and some leasehold properties. We advise on this during your free survey.
Detached, semi-detached, and terraced homes typically do not require planning permission to replace a door. All installations comply with UK building regulations and are backed by our Insurance Backed Guarantee.
Your new door must match the character and appearance of the property. We advise on permitted development rules and can liaise with your local authority where needed.
Changes to the exterior of a listed building require specific consent. We assess suitability during the survey and can recommend appropriate door styles that meet listed building requirements.
If you own a leasehold flat, you may need permission from your freeholder or management company before replacing a door. We advise on this upfront so there are no delays.
