Headquarters:
Mansfield, Nottinghamshire, United Kingdom.

Integrated Doorsets is more than a conventional internal door manufacturer. It produces complete, tested doorsets for healthcare, education, residential, commercial, and leisure buildings. Design, manufacturing, product testing, and compliance management are handled through one coordinated system.

This internal door company operates three manufacturing and fabrication facilities in Mansfield.

Sentry Doors-Top 10 Internal Door Companies in the UK
No. 5

Type of Business:
Certified timber fire and security doorset manufacturer.

Headquarters:
Doncaster, South Yorkshire, United Kingdom.

Year Founded:
1989

Fire safety is the central focus of Sentry Doors. The company supplies social housing, healthcare, education, public-sector, residential, and commercial developments. Its products are manufactured at a specialist facility in Doncaster.

Most orders involve complete doorsets rather than separate door leaves. Single-leaf products arrive pre-hung, pre-assembled, and prepared for installation. Frames, hinges, locks, and other specified hardware are fitted under factory-controlled conditions.

Main Products:
  • FD30 and FD60 fire doorsets
  • Internal apartment entrance doorsets
  • Communal fire doors
  • Security-rated doorsets
  • Glazed fire doors
  • Veneered fire doors
  • Laminate fire doors

Each applicable fire door receives a digital identification tag during manufacture. Building managers can access its manufacturing, installation, inspection, and maintenance records through an app. This supports the Golden Thread requirements of modern building management.

The pre-assembled format also limits on-site alterations. This is important because incorrect fitting can affect the tested performance of a certified fire doorset.

No. 6

Type of Business:
Family-owned manufacturer of bespoke timber doorsets, fire doors, and glazed screens.

Headquarters:
Darwen, Lancashire, United Kingdom.

Year Founded:
1957

Pendle Doors began as a small Burnley door business in 1957. It remains family-run and now manufactures from two sites in Lancashire. Its main Darwen facility covers approximately 33,000 square feet. A further 15,000-square-foot site was added to expand production.

Its healthcare doors are developed around demanding access and durability requirements. Pendle coordinates specialist glazing, facings, and hardware when a standard assembly cannot meet the specification.

GE Door Manufacturing-Top 10 Internal Door Suppliers in the UK
No. 7

Type of Business:
Bespoke timber doorset, glazed screen, and integrated ironmongery manufacturer.

Headquarters:

2006.

GE Door Manufacturing operates an 85,000-square-foot production facility in South Wales. It supplies healthcare, education, commercial, and residential developments throughout the UK.

  • Acoustic doorsets
  • Security doorsets
  • Hygrothermal doorsets
  • Timber door frames

This top British internal door company has demonstrated its capacity on demanding construction programs. One student accommodation project required 6,000 severe-duty, laminate-faced doorsets. Another hospital redevelopment used 1,050 doorsets with integrated ironmongery.

The Heritage Collection-Top 10 Internal Door Companies in the UK
No. 8

Type of Business:
Family-owned solid timber internal door and joinery manufacturer.

Headquarters:
Killamarsh, Sheffield, United Kingdom.

Year Founded:
Mid-1990s

The Heritage Collection began by producing a small number of oak doors in the mid-1990s. It has since developed into a major British producer of solid timber doors.

Its Sheffield operation manufactures up to 2,000 doors per month. Oak and pine remain central to the collection, while the wider range includes flooring, stair parts, and timber mouldings.

Main Products:
  • Solid oak internal doors
  • Solid pine internal doors
  • Ledged doors
  • Framed and ledged doors
  • Contemporary panel doors
  • Traditional panel doors
  • Sliding and bi-fold doors
  • FD30 and FD60 fire doors
  • Door linings and architraves
Advantage:

Heritage differs from manufacturers that rely mainly on veneered or moulded door skins. Its core residential collection uses solid oak or pine, giving every door natural variations in grain and character.

UK manufacturing makes non-standard sizing easier to manage. Selected styles can be produced up to 1,050 by 2,150 millimeters. The company has also invested in CNC equipment for repeatable custom production.

The factory sources much of its oak directly from French sawmills. Timber passes through the company’s PEFC certification system, supporting traceable material sourcing.

Longden Doors-Top 10 Internal Door Brands in the UK
No. 9

Type of Business:
Bespoke solid hardwood door and performance doorset manufacturer.

Headquarters:
Newton Aycliffe, County Durham, United Kingdom.

Year Founded:
1838

Longden Doors traces its history to 1838, making it one of the UK’s longest-established bespoke door manufacturers. The company began in construction and architectural joinery before shifting its focus to high-quality solid timber doors in 1978. Its products are still manufactured at its factory in County Durham.

The business combines traditional woodworking skills with modern performance requirements. Its solid hardwood doors are supplied to luxury homes, hotels, commercial interiors, heritage properties, and conservation projects.

Main Products:
  • Bespoke internal doors
  • Solid hardwood panelled doors
  • Boarded timber doors
  • Glazed doorsets
  • Pre-hung doorsets
  • FD30 and FD60 fire doors
  • Acoustic doorsets
  • Smoke-control doors
  • Security doorsets
  • Matching timber frames and architraves
  • Custom ironmongery packages
Advantage:

Longden does not focus on standardized, mass-produced doors. Each door can be adapted to the required dimensions, timber species, panel arrangement, glazing, mouldings, hardware, and technical performance. This gives architects greater freedom when a standard catalogue product cannot match the building.

Frames can be manufactured from the same solid hardwood as the door leaf. The complete product can also be supplied as a factory-prepared, pre-hung doorset with matched ironmongery. Fire resistance up to FD60 and acoustic performance up to 37 Rw dB are available within selected configurations.

This internal door company in Britain is particularly suited to luxury residences, boutique hotels, historic buildings, and conservation-led refurbishment. Its published project portfolio includes Kensington Palace, Windsor Castle, 10 Downing Street, Buckingham Palace, Hampton Court Palace, and Tate Britain.

Longden’s ability to reproduce traditional architectural details is a major advantage in listed buildings. Doors can retain the appearance of original joinery while incorporating modern fire, smoke, acoustic, and security performance.

FAQs About British Internal Doors

What types of internal doors are commonly available in the UK?

Popular options include moulded doors, flush doors, veneered doors, solid timber doors, glazed doors, sliding doors, and pocket doors. Many manufacturers also produce fire-rated, acoustic, and security-rated doorsets.

Are solid timber doors better than engineered doors?

Solid timber offers natural grain and traditional character. Engineered doors usually provide better stability and consistent performance. The right option depends on the design, budget, opening size, and performance requirements.

Is it better to order complete doorsets?

Complete doorsets are often better for commercial and multi-unit projects. Components are prepared together and can arrive pre-hung. This reduces site work and helps maintain consistent performance across repeated openings.

Do internal doors come with handles?

Some internal doors with handles are sold as complete doorsets. Others require handles, hinges, and locks to be purchased separately.

What are the best internal bedroom doors?

Solid-core, moulded, oak, and white-primed doors are popular choices. Solid-core doors provide better sound insulation and durability.

When are internal fire doors required in the UK?

Internal fire doors in the UK are commonly required along protected escape routes, in flats, and between garages and homes. Always confirm local building regulations.

Where can I buy cheap internal doors?

Affordable internal doors are available from builders’ merchants, home-improvement stores, online door retailers, and manufacturer outlet sections. Compare delivery fees, hardware costs, dimensions, and warranties before ordering.

How much do internal doors with glass cost in the UK?

Internal glazed doors typically cost £100–£300 per door. Basic white-primed models start at about £98, while oak, fire-rated, or bespoke designs cost more. Handles, frames, delivery, and installation are usually extra.
