7 Best Bespoke Access Panels for Non-Standard Openings in the UK (2026)

Compare seven bespoke access panels for non-standard openings in the UK in 2026, exploring custom sizes, materials, design options, and practical applications.

Standard sizes fail at the worst moment. The structural opening is 20mm out, the wall build-up is thicker than expected, the ceiling void is shallow, or the finish has to match a tiled wall exactly. For UK contractors, developers, architects and facilities managers, that mismatch can mean extra framing work, poor edge lines and repeat visits. Bespoke access panels address this by being made to an agreed size for the opening rather than forced to fit it. Rated panels should not be cut or modified unless the change is expressly permitted within the manufacturer's documented system.

Our top pick is Access Panels Direct for specifiers who need a configurable made-to-order panel from a single UK supply route, covering custom dimensions, frame styles, RAL finishes, locking options and performance options where applicable. Its specification support helps match the panel and frame to the structural opening, with the fire rating, finish and locking requirement considered on a project-by-project basis. For projects where certified fire, acoustic or airtight performance is the driving requirement, Palco UK Ltd is the strongest alternative. For slim-profile or tiled-wall applications, Ceildoor Products Limited is the most focused option.

The seven suppliers below are compared on dimensional configurability, UK supply credentials, frame and finish choice, locking and performance options, lead time clarity and suitability across commercial and residential work. Each one addresses a different version of the non-standard opening problem, with a best-for verdict to help you build a practical shortlist for your project in 2026.

How We Ranked These

Specification fit comes first. The ranking favours suppliers whose ranges help specifiers match a panel to an opening, understand the UK supply route and documentation, and plan installation around realistic tolerances rather than catalogue size alone.

Dimensional Configurability And Tolerance Control

We prioritised made-to-measure capability over a choice of three stock sizes. That means custom height and width to suit the structural opening, clear guidance on measuring, and an agreed tolerance between opening and frame. A bespoke size does not automatically correct an out-of-square opening, so a site survey, rectification of damaged reveals and tolerance agreement remain important steps before manufacture, whatever the chosen supplier.

UK Supply And Manufacturing Provenance

All seven options have UK supply routes, with several manufacturing in Britain. Own manufacture, UK stockholding and trade distribution give buyers different procurement routes to consider alongside lead times, colour requirements and aftercare arrangements. For public frameworks and developer programmes, British manufacture and clear provenance can also support the paperwork needed for procurement and subsequent replacement ordering.

Frame Styles And Finish Integration

Frame detail decides whether a panel disappears or stands out. We looked for choice between visible picture-flange frames that sit on the face and plastered-in beaded frames designed to blend with skimmed plaster. Finish flexibility also matters, including polyester powder coat to RAL colours and face types that accept paint or plaster skim, as well as tile-ready options for walls, ceilings and service risers.

Locking And Performance Options

Access frequency and security vary from a domestic loft to a hospital riser. We compared touch-latch, key lock, tamper-resistant and budget lock choices, plus performance variants where available. Fire, acoustic, air sealed or smoke performance belongs to a specific model, permitted size, orientation and build-up with a defined field of application; it should never be treated as a blanket guarantee across a supplier's range.

Lead Time Clarity And Programme Fit

Made-to-measure takes longer than picking from stock. We favoured suppliers that distinguish clearly between stocked lines and made-to-order production, explain what information is needed to release an order for manufacture, and support programme planning. Responsiveness of technical advice, availability of certification documents and straightforward trade ordering all counted here, alongside the practical distinction between an enquiry response and a production slot.

Suitability For Commercial And Residential Projects

Non-standard openings occur in both sectors, from plant rooms and riser shafts to understairs cupboards and loft conversions. We considered suitability for single one-off replacements as well as multi-unit new build, refurbishment and maintenance programmes. Support for design teams through BIM, CAD and specification documents also matters where those tools are offered and needed for the project.

#1. Access Panels Direct - Best For Full Specification Configurability

A single-source made-to-measure route for awkward openings where size, frame, finish, lock and performance must be matched together.

Access Panels Direct focuses on made-to-measure supply with specification support that helps contractors, developers, architects and facilities managers align the panel and frame with the structural opening, fire rating, finish and locking requirement. Its dedicated range of bespoke access panels is built to the specifier's exact dimensions, with configurable frame styles, locking mechanisms and RAL colour finishes, plus performance options where applicable to the selected product.

The range covers both visible picture-flange types that sit on the wall or ceiling face and plastered-in beaded types intended to blend with the surrounding plaster finish. That choice matters on retrofit work where wall build-up, tile thickness or ceiling constraints dictate edge detail. A custom size does not automatically correct an out-of-square or damaged structural opening, so measure in two positions for each dimension, rectify where needed and agree manufacturing tolerances before the order is frozen.

Key Specs:

• Made-to-order panels built to specifier-supplied dimensions

• Configurable frame styles including picture-flange and beaded plastered-in types

• Polyester powder-coat finish options to RAL colours

• Choice of locking mechanisms to suit access frequency and security

• Performance variants available where applicable, subject to model, size, orientation and build-up

• Specification support for matching panel to structural opening

Pros:

• Covers dimensions, frame, finish, lock and performance coordination from one UK source

• Picture-flange versus beaded choice helps detailing for both retrofit and new plaster work

• RAL finish flexibility aids integration with decorated walls and ceilings

• Specification support useful where opening sizes vary across a refurbishment programme

Cons:

• Made-to-order production takes longer than stocked standards, so it does not suit same-day emergency replacement

• Third-party certified fire or acoustic performance to a named standard is specific to the exact product, permitted size and field of application

Who It's Best For: Contractors, developers, architects and facilities managers who want one configurable supply route for varied non-standard openings across walls and ceilings.

#2. Exitile Access Ltd - Best For Large Commercial Projects And Distributor Supply

A distribution-led access solution for commercial programmes procured through established trade channels.

Exitile Access Ltd, based in Desford in Leicestershire, supplies riser doors and access panels for residential and commercial spaces. The business has operated since 2012 and draws on more than 25 years of combined industry expertise. It works with leading national distributors while supporting contractors and developers directly, with made-to-order solutions aimed at large commercial projects.

That model suits main contractors and developers who order in volume, need supply across plots or phases, and prefer to procure through familiar distributor accounts. Its focus on access solutions keeps discussions centred on door and panel detailing, including ironmongery and installation sequencing. On complex commercial jobs, the distributor route also gives buyers a familiar channel for arranging call-offs and coordinating site deliveries.

Key Specs:

• Riser doors and access panels for residential and commercial use

• Made-to-order solutions for large commercial projects

• Supply through leading national distributors plus direct contractor support

• UK base in Desford, Leicestershire, operating since 2012

• Team background with more than 25 years of industry expertise

Pros:

• Well aligned with contractor procurement through national distribution

• Experience across both residential and commercial applications

• Focused access-product scope rather than a broad general catalogue

• Practical fit for phased developments needing repeatable supply

Cons:

• Made-to-order solutions need agreed dimensions and configurations before production, including for single one-off replacements

• Drawings and panel details need coordinating with the order, even where the purchase goes through an established distributor account

Who It's Best For: Contractors and developers on larger commercial schemes buying through distributor networks.

#3. Ceildoor Products Limited - Best For Slim-Profile And Tiled-Wall Applications

A specialist option where depth, surface finish or the ceiling system rules out a standard panel.

Ceildoor Products Limited concentrates on application-led detailing. Its slim range uses a 25mm overall frame depth for zones where void or wall depth is constrained. Alongside standard and Unihatch types, it offers panels for tiled walls and exposed ceiling grid systems, plus circular formats, acoustic and air sealed variants, bespoke sizes and a choice of locks.

That breadth helps on refurbishments where finishes drive the specification. Tile-ready detailing allows the tiler to continue the wall pattern across the door face with cleaner joints. Grid-compatible types suit commercial ceilings where tile lift-out access is needed without disturbing the surrounding system. Fire-rated options at one hour and two hours are available in defined models, subject to permitted size, orientation and installation build-up rather than the range as a whole.

Key Specs:

• Slim type with 25mm overall frame depth

• Tile-ready panels and exposed ceiling grid compatible panels

• Circular formats and bespoke sizes within the range

• Fire-rated variants at 1HR and 2HR in defined models

• Acoustic and air sealed options plus Unihatch and everyday types

• Choice of locking mechanisms

Pros:

• Slim 25mm overall frame depth offers an option for shallow voids and thin partitions, subject to the installation build-up

• Tile and grid compatibility addresses two common finish clashes

• Circular and bespoke formats extend choice beyond rectangular standards

• Fire, acoustic and air sealed variants available in defined configurations

Cons:

• The 25mm dimension is overall frame depth, so the opening and surrounding construction still need to suit the selected panel

• Certified performance depends on the specific model, permitted size, orientation and build-up, so early coordination on field of application is essential

Who It's Best For: Specifiers dealing with tiled walls, shallow depths, ceiling grids or circular apertures.

#4. Access Building Products Ltd - Best For Public-Sector And Contractor Supply Chains

A UK manufacturing route with design-team tools and a broad hatch range for mixed portfolios.

Access Building Products Ltd is based in Tockwith in North Yorkshire and has operated since 2006. It manufactures the majority of its products in-house and supplies access panels, loft hatches, roof hatches and associated products to private and public sectors. Products are used by contractors and developers across the UK and abroad. Support for design teams includes BIM Revit and IFC objects plus CAD details, alongside a bespoke panel builder for custom dimensions, RAL finishes and fire-rated configurations.

That combination suits estates, housing associations, schools and healthcare refurbishments where drawings, schedules and repeat ordering matter. Being able to schedule wall panels alongside loft and roof hatches from one manufacturer reduces the number of supply routes to manage. The bespoke builder helps where openings fall between standards, while BIM and CAD content supports architects preparing drawings and schedules at tender stage.

Key Specs:

• UK manufacture for the majority of products, based in Tockwith

• Operating since 2006 serving private and public sectors

• Access panels plus loft hatches, roof hatches and associated products

• Bespoke panel builder for custom dimensions, RAL colour and fire-rated configurations

• BIM Revit, IFC and CAD support for specification

• A mixed schedule of panels, loft hatches and roof hatches still needs product-specific dimensions, installation details and performance requirements

Who It's Best For: Public-sector teams, contractors and developers needing UK-made panels and hatches with proper specification content.

#5. Palco UK Ltd - Best For Certified Fire, Acoustic Or Airtight Performance

The performance-led choice where compliance and test evidence drive the schedule.

Palco UK Ltd offers an extensive range of access panels and riser doors for walls and ceilings, designed for straightforward installation and maintenance. The range includes variants with fire, acoustic, airtight and smoke certifications in defined configurations, with each requirement tied to the relevant product. Its FlipFix range is designed to save time and cost on installation, which helps on tight programmes and occupied refurbishments where the substrate and opening are suitable.

For specifiers, the value is in matching performance to location. A riser in a compartment wall has different demands from a panel in an acoustic partition or a ceiling hatch in a pressure-controlled zone. Palco covers projects of all sizes, so a single schedule can mix wall and ceiling types while keeping certification paperwork with one supplier. As with any rated product, the rating holds only for the tested model, permitted size, orientation and surrounding construction.

Key Specs:

• Access panels and riser doors for walls and ceilings

• Fire, acoustic, airtight and smoke certified variants in defined configurations

• FlipFix range for faster installation

• Suitable for projects of all sizes from single units to large schemes

• Range designed for easy installation and maintenance

Pros:

Cons:

• Time savings from FlipFix depend on substrate and opening preparation, so poorly prepared reveals still need rectification

• Certification applies to the exact product, permitted size, orientation and build-up within its field of application

Who It's Best For: Specifiers where fire, acoustic, airtight or smoke performance must be evidenced for building control or client sign-off.

#6. Jupiter Blue - Best For Responsive Technical Support

A trade-friendly contact point where quick sizing and documentation advice helps move decisions along.

Jupiter Blue handles technical advice, bespoke sizes and trade enquiries Monday to Friday from Unit 86 Marston Moor, Tockwith, YO26 7QF. Its technical enquiry service typically replies within two hours, which helps when a plot needs sizing advice or a fire certification document is holding up a submittal. Bespoke sizes and supporting paperwork are dealt with through the same technical contact, keeping those discussions together.

That responsiveness suits contractors and designers juggling multiple openings with slightly different constraints. The specifier can send opening sizes, wall or ceiling build-up and finish intent for a practical steer on the appropriate panel. Direct trade enquiry handling also keeps pricing and delivery discussions together, which is useful for small builders and maintenance teams as well as larger firms managing several openings.

Key Specs:

• Bespoke sizes available to suit non-standard openings

• Fire certification documentation available on request for defined products

• Technical support Monday to Friday, typically replying within 2 hours

• Direct handling of trade enquiries

• Base at Tockwith in North Yorkshire

Pros:

• Two-hour typical technical response helps time-sensitive specification decisions

• Single contact for sizing queries and certification paperwork

• Direct trade handling reduces procurement steps

• Weekday availability aligns with site and studio workflows

Cons:

• Support hours are Monday to Friday only, so weekend reactive work needs advance planning

• Technical responsiveness relates to advice and documents, not manufacturing or despatch speed, so programme allowances for made-to-order production still apply

Who It's Best For: Specifiers and trade buyers who value fast, practical technical guidance on custom sizing and documentation.

#7. M & M Access Ltd - Best For UK-Manufactured Panels With RAL Colour Flexibility

A British factory option where face type and exact colour must be coordinated together.

M & M Access Ltd manufactures its access panels and riser doors in the UK from its base on the Moulton Park Industrial Estate in Northampton. The range includes metal-faced, plasterboard-faced and tile-accepting types, available as non-fire rated, fire-rated and acoustic-rated variants in defined configurations. Several locking options are offered, with a standard white finish to RAL 9010 and powder coating to any RAL colour where specified for the order.

That mix helps designers address finish and performance in one order. A metal face suits frequent-access service zones, while plasterboard faces suit decorated walls and ceilings where concealment matters; tile-ready faces provide an option for bathrooms and kitchens. Any-RAL powder coating allows matching to brand colours, feature walls or existing joinery, provided the RAL reference is agreed before coating and carried through the panel schedule.

Key Specs:

• All panels and riser doors manufactured in the UK

• Metal-faced, plasterboard-faced and tile-accepting face types

• Non-fire rated, fire-rated and acoustic-rated variants in defined configurations

• Several locking options to suit security and access frequency

• Standard white to RAL 9010 with powder coating to any RAL colour

• Base in Northampton, founded in 2003

Pros:

• UK manufacture for projects with domestic provenance requirements

• Any-RAL powder coating supports precise colour integration

• Three face types from one factory simplify mixed wall and ceiling schedules

• Fire-rated and acoustic-rated variants available alongside standard types

Cons:

• Any-RAL and tile-ready coordination needs accurate colour references, tile thickness and tolerance agreement before production

• Face type, finish and locking options need coordinating for each panel, especially where one schedule includes several wall and ceiling applications

Who It's Best For: Specifiers needing British-made panels in a specific RAL colour across metal, plasterboard or tiled finishes.

Frequently Asked Questions About Custom Panels For Awkward Openings

What Is A Custom-Made Panel And When Do You Need One Instead Of A Standard Size?

A custom-made panel is manufactured to an agreed size for your structural opening rather than cut down on site. You need one when height, width, depth, frame style or finish falls outside stock sizes, or when tiles, grids or shallow voids rule out standards. If a stock unit would need packing, trimming or forced fitting, consider a made-to-measure unit with the opening dimensions and fitting allowance agreed before ordering.

How Do You Measure A Non-Standard Opening For A Made-To-Order Panel?

Measure the structural opening in at least two positions for both height and width, plus reveal depth and squareness. The structural opening is the space receiving the frame; the clear access opening is the usable space left once the frame and door are fitted. Confirm both, particularly where equipment must pass through the panel. Record the actual dimensions, wall or ceiling build-up, finish thickness and any skirting, tiling or grid interference, then obtain the supplier's required fitting allowance and order-size convention rather than automatically deducting a tolerance. Photograph the reveal and agree who rectifies out-of-square or damaged edges before production.

Can Made-To-Order Panels Be Fire Rated And What Should Specifiers Check?

Yes, defined models can carry fire ratings, commonly one hour or two hours, but the rating is never universal. Check the exact product, permitted sizes, orientation for wall or ceiling use, surrounding construction and installation method against the test evidence and field of application. Keep the certificate and installation instructions with the handover pack for building control and future reference.

What Frame Styles, Finishes And Locking Options Are Typically Available?

Most ranges offer a visible picture-flange frame and a beaded frame for plastered-in concealment, with metal, plasterboard or tile-ready door faces. Finishes commonly include white powder coat to RAL 9010 with any-RAL coating to order, alongside paint-grade or skim-ready faces. Locks range from touch-latch for discreet access to key, tamper-resistant and budget locks for risers and communal areas, depending on the selected product.

How Long Does Manufacture And Delivery Take In The UK?

Stocked standards can despatch quickly, while made-to-measure units need manufacturing time after dimensions, finish, lock and any performance variant are frozen. Allow time for the survey and tolerance agreement, followed by coating, quality checks and courier or pallet delivery to site. For programme certainty, establish the production slot, what stops the clock and whether phased call-offs are possible before placing the order.

Are Custom Panels Suitable For Tiled Walls Or Exposed Ceiling Grids?

Yes, provided you choose an application-specific type. Tile-ready doors are detailed to carry tiles with the correct weight allowance and grout lines, while grid-compatible types suit lay-in ceiling systems without disturbing adjacent tiles. Share tile size and thickness, grid profile and access frequency with the supplier so the hinges and locks are matched to the load and intended use.

What Information Do You Need To Provide When Ordering A Custom-Sized Panel?

Supply opening height and width with measuring positions, reveal condition and squareness, wall or ceiling construction and finish thickness, and required frame style. Add the RAL colour reference if coated, lock type, hinge side where relevant, and any fire, acoustic or air sealed requirement with location drawings. Clear photos and a dimensioned sketch help reduce remakes and site delays by keeping the opening details together.

Final Verdict And Next Steps

Non-standard openings reward careful measurement and accurate specification. Match the frame to the finish and the lock to the access frequency, then match any rated variant to its exact model, permitted size, orientation and build-up. For most UK refurbishment and new-build schedules, a configurable single source is a useful starting point, with specialists considered where depth, finish or certification requirements narrow the choice.

If you are weighing up bespoke access panels for a difficult opening, start with Access Panels Direct for coordinated sizing, frame, RAL finish, locking and performance planning, then compare Palco UK Ltd for certification-led work and Ceildoor Products Limited for slim or tiled details. A short measured sketch sent to your shortlist will help establish which supplier and configuration fit your opening, finish requirements and programme best.
