If you are planning a new set of bi‑fold doors, you want clear figures, realistic timelines, and a smooth fitting day. This guide explains typical UK price ranges, what changes the cost, how long the process takes from survey to sign‑off, and how Clearview 2000 keeps installations tidy and on schedule across Hertfordshire, Essex, Bedfordshire, and London.

How much do bi‑fold doors cost in the UK?

Prices vary with size, material, and options. As a helpful starting point for a standard rear opening with double glazing and a quality, well known system, here are indicative supply and install ranges:

• uPVC bi‑fold doors: £3,500 to £6,500 for 3 to 4 panels; £5,500 to £8,500 for 5 to 6 panels
• Aluminium bi‑fold doors: £5,500 to £9,500 for 3 to 4 panels; £8,000 to £13,500 for 5 to 6 panels

These ranges include survey, standard colours, hardware, toughened double glazing, and professional fitting. Premium systems, non standard colours, and extra features will add to the total. Aluminium usually costs more than uPVC because it offers slimmer sightlines, excellent strength, and long term stability on larger spans.

Please note, these prices are typical UK price ranges and are in no way an accurate quote from Clearview 2000 Ltd.

What is the average cost of installing a bi‑fold door?

For a typical family home replacing a dated patio set with a new 3 panel configuration:

• Average fully fitted uPVC 3 panel set: £4,000 to £5,500
• Average fully fitted aluminium 3 panel set: £6,000 to £8,000

For larger openings or a new extension with 4 to 6 panels:

• Average fully fitted uPVC 4 to 6 panel set: £6,000 to £8,500
• Average fully fitted aluminium 4 to 6 panel set: £8,500 to £12,500

Every project is unique, so use these as planning figures. You will receive a clear, itemised quotation after survey that reflects your exact sizes, configuration, and chosen options.

What changes the price?

Several choices and site factors influence your final cost. The biggest ones are:

• Size and panel count: Wider openings and more panels need more material and hardware; labour time also increases.
• Material: uPVC is budget friendly and low maintenance; aluminium offers slimmer frames, excellent rigidity, and premium finishes at a higher price point.
• Configuration and access: Odd shaped openings, corner sets, or openings that require a new lintel or steel add to cost. Restricted access can extend labour time.
• Finishes and colours: Standard white or popular stock colours are cost effective. Dual colour or bespoke RAL, woodgrain foils, and marine grade finishes add to the price.
• Glazing: Standard toughened double glazing is most common. Triple glazing, laminated security glass, solar control, acoustic laminates, or integral blinds increase cost.
• Thresholds: Standard weathered thresholds are included. Low thresholds improve step over comfort and accessibility but may require additional weathering details or internal trim.
• Integrated blinds: Between glass blinds provide privacy and solar control without cleaning. Expect a noticeable uplift per panel due to specialised units.
• Security specifications: Many systems can be specified to meet Secured by Design with enhanced locks, keeps, cylinders, and laminated glass. This adds cost but can be a smart long term choice.
• Trims and making good: New plaster returns, skirting adjustments, cills, and external render or cladding repair will be itemised as required.

Do bi‑fold doors add value to your house?

In many cases, yes. Bi‑fold doors improve light, flow, and connection to the garden. These are strong lifestyle features that help homes feel larger and more modern. Buyers notice the quality of the opening to outdoor space, especially in kitchen/dining rooms and extensions. While no installer can guarantee a pound for pound uplift, agents often report improved saleability and stronger viewing interest where high quality bi‑folds are in place with clean finishes, smooth operation, and good energy performance.

How long does it take to install bi‑fold doors?

There are two timelines to consider: end to end and fitting day.

• Survey to installation: 3 to 6 weeks is typical. Lead times depend on system choice, colour, and glass options. Bespoke colours or integral blinds often sit toward the longer end. Your surveyor will confirm sizes,configuration, lintel status, and any making good.
• On site installation: Most straightforward replacements complete in 1 day for a 3 to 4 panel set. Larger sets or structural adjustments can take 1 to 2 days. Final glazing, toe and heeling, weatherproofing, trims, anda full operation check are included. You will receive guidance on first day care and maintenance.

Clearview 2000’s clean, punctual fitting approach

You want a tidy job with minimal disruption. Clearview 2000’s installers arrive on time, protect floors and work areas, and keep the site clean as they go. Old frames and glass are removed carefully and disposed of responsibly. Frames are plumbed and levelled, panels are correctly toe and heeled, and all seals, drainage, and locking points are checked before sign‑off. If any factory component needs adjustment, a prompt remedial visit is arranged. Installations are backed by a 10 year guarantee on products and workmanship, with responsive aftercare from a friendly, local team.

Security options, including Secured by Design

Modern bi‑folds are secure when specified and fitted correctly. Clearview 2000 can supply systems with multi point locking, shootbolts, anti lift tracks, and quality cylinders. Where available, we will specify components to meet Secured by Design, and we can add laminated glazing to slow forced entry. Ask your surveyor to explain the differences between cylinder classes, glazing choices, and handle or key options to match your security expectations.

Energy performance and comfort

Today’s frames include thermal breaks and warm edge spacers that limit heat loss. With A rated double glazing or even triple glazing on request, your new doors can help maintain comfort year round. Good fitting is critical to performance. Accurate survey, correct packers, continuous seals, and proper drainage keep drafts and moisture at bay. If you are planning a wider project, you can combine new doors with upgrades to your windows for a consistent look and performance across the home. If you are browsing options, you might also compare configurations like sliding doors, which can deliver larger uninterrupted panes for certain openings.

Quick budgeting checklist

• Measure your opening width and height; note how many panels you prefer and your primary opening direction.
• Decide on material: uPVC for value; aluminium for slim sightlines and larger spans.
• Pick a finish: standard colours keep costs lean; dual colour and foils add cost.
• Confirm glazing: standard toughened double glazing suits most homes; consider laminated security glass or solar control if needed.
• Think about thresholds and accessibility; agree weathering details with your surveyor.
