How to Choose a Front Door That Adds Kerb Appeal and Security to Your Home

A front door has to do two jobs at once and they pull against each other, because the things that make a house look good from the pavement, glass panels, panelling, a bit of colour, are the same things you have to think carefully about when it comes to keeping people out.

The short version of the answer, before any of the detail: a solid or composite leaf, a frame fixed properly into the masonry, a multipoint lock with a TS007 3 star cylinder, and somebody competent fitting it. Colour comes last, and it still matters more than people expect.

Front Door Security Comes Down to Three Parts: the Leaf, the Frame and the Lock

Three parts decide it, and a weakness in any one of them cancels out the other two.

The leaf is the door itself and it needs enough substance to survive being kicked or rammed, so a solid or composite core with a decent thickness rather than a thin hollow panel. The frame is the part people forget about, and it has to be anchored into the structural wall rather than just screwed to the surface of the reveal, because most forced entries on UK front doors go for the frame and the lock rather than trying to smash through the middle of the door. The lock should be a multipoint system that throws bolts at three or more points around the perimeter when you turn the key, which spreads the load and makes levering or kicking a lot less useful.

PAS 24 Is the Security Standard to Ask For, and Replacement Doors Do Not Legally Need It

The standard to look for is PAS 24, currently PAS 24:2022, which tests a complete doorset against the attack methods actually used in break ins, including mechanical loading of around 450kg on the lock and hinge sides.

Approved Document Q makes PAS 24 a requirement on new build homes, but a replacement door in an existing house is not legally required to meet it, which is exactly why you need to ask rather than assume. If you want the shorthand version, ask whether the door is Secured by Design, because that is the police backed scheme and it sits on top of PAS 24 with extra requirements on the cylinder and hinges.

A TS007 3 Star Cylinder Stops Lock Snapping and Costs £20 to £40 if You Specify It Upfront

Lock snapping is the most common method of forced entry on UK doors, and it targets the euro cylinder rather than the door.

A TS007 3 star cylinder has a sacrificial break point and a reinforced core, so even if the front of it snaps off the back half keeps holding, and it also resists drilling, picking and bumping. You can reach the same rating with a 1 star cylinder plus 2 star hardware such as a security handle or a cylinder guard, though the 3 star cylinder on its own is simpler.

The money on this is small enough that there is no argument for skipping it. Specified with the door it adds roughly £20 to £40. Doing it afterwards costs £30 to £80 for the cylinder plus £50 to £100 for a locksmith. Also check that the cylinder does not stick out more than about 3mm past the escutcheon, because anything proud of the surface is easier to grip and snap.

Timber, Composite and uPVC Compared on Price, Maintenance and What Each One Suits

Timber gives you a warmth and a paint finish nothing else quite matches, but it moves with the weather and it needs looking after. Composite is a solid core with a GRP skin over it, so you get the look of a painted timber door with better insulation and no swelling in winter, and composite ranges from suppliers like Direct Doors cover most standard sizes without a bespoke lead time. uPVC is the cheapest and performs perfectly well on weather and security, it just has a limited range of looks and tends to announce roughly which decade it was fitted in.

Whatever Material You Pick, the Door Leaf Must Hit 1.4 W/m²K or Better Under Part L

That figure applies to replacement doors, not just new builds, so ask for the U value in writing before you sign anything. It is the one number on the quote that is a legal requirement under Approved Document L.

Deep Blues, Greens and Black Age Best, and the Door Style Should Match the Age of the House

This is the part that changes how the house reads from the other side of the road, and it costs nothing extra to get right.

Deep blues, forest greens and a proper black sit well against most brick and render and do not date the way a fashionable shade will after a few years. The style needs to answer the house rather than your Pinterest board, so a Victorian terrace wants a panelled door with traditional proportions, and a modern build wants something flush or close to it, because a panelled door on a flat fronted new build always looks slightly borrowed.

Any Glass Within 800mm of the Lock Has to Be Laminated

Glazing brings light into a hallway and makes an entrance feel less like a bunker, and it is also the bit that needs specifying carefully.

Laminated safety glass goes in any glazed element, always, both for the injury risk and because ordinary float glass gives way in one hit. PAS 24 requires any glazing within 800mm of the lock to be laminated, and that is a straightforward thing to check on a quote, so check it. If privacy matters, obscure or frosted panels give you the light without the view in, and sidelights beside the door do the same job as glass in the leaf while keeping the glazing further from the lock.

A Badly Fitted Good Door Performs Worse Than a Cheap Door Fitted Properly

The frame goes in level, plumb and square, with the fixings going into the structural wall.

The threshold and perimeter seals should compress evenly all the way round when the door shuts, otherwise you get draughts down one edge and water sitting on the threshold. And the multipoint lock wants adjusting so every point engages smoothly with the handle lift, because a lock that fights you is a lock that gets left unengaged on the school run, and at that point everything else on this page has been paid for and switched off.
