Why choose uPVC sliding patio doors in Hatfield?
The right door depends on the opening, the room and the way you use the garden. Here is how uPVC sliding patio doors tend to work out in practice:
If the windows on your Hatfield home are white or woodgrain uPVC, uPVC sliding patio doors in a matching finish keep the rear of the house looking uniform.
Planning a door wider than about 3.6 m for your Hatfield home? That is beyond the uPVC range, so aluminium or a multi-track system would be the next step.
- Compressible gaskets and brush pile seals along the interlock reduce the draughts and rattles that an older patio door with worn seals often suffers from.
- A two-panel uPVC slider usually fits the same opening as an old patio door, so a straight swap avoids building work and typically takes a day.
- Shoot-bolt or hook locking on the sliding panel, plus anti-lift devices, help stop the panel being lifted or levered out of the frame from outside.
Daylight in Hatfield and what it means for your glass
At the latitude of Hatfield, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 47 min against 16 h 41 min in midsummer. A south-facing uPVC sliding patio door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.
uPVC sliding patio doors prices in Hatfield

What happens when you order uPVC sliding patio doors in Hatfield?
Here is the usual sequence in Hatfield: guide price, free survey, written quote, then manufacture (typically 2–4 weeks from survey sign-off). Fitting typically takes 1 day for a straight swap in an existing opening. Nearby, we also survey in Welwyn Garden City, St Albans and Hertford.
Do you need approval in Hatfield?
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Choosing the specification
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- Handles. Lever or pull handles in white, black, chrome or gold-effect finishes, with a key lock on the outside.
Questions about uPVC sliding patio doors in Hatfield
Can you match other doors and windows in my Hatfield home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
Are uPVC sliding doors secure?
uPVC sliding doors are secure when the sliding panel has multi-point locking, anti-lift protection and steel reinforcement in the frame. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets. Laminated glass adds resistance to breaking through, and a key-locking handle stops the door being opened from inside if a pane is broken.
How much do uPVC sliding patio doors cost?
uPVC sliding patio doors start from a guide price of £1,695 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £2,195–£2,695, and a 3.6 m three-panel door is around £2,895. Coloured foils, glass upgrades and a low threshold move the figure up, and the final price is fixed in a written quote after survey.
What sizes do uPVC sliding doors come in?
uPVC sliding doors are made to measure, so they come in any size within the system limits rather than set sizes. Our uPVC range covers overall widths from about 1.5 m to 3.6 m at standard 2.1 m height. Two panels cover most openings up to about 3 m, and beyond that a third panel is added. For larger openings, aluminium carries bigger panels.
