The route is straightforward:

​

1. Register with the Architectural Partner Network.

2. Apply to become an APN Verified Member.

3. Complete the APN verification process.

4. Select your window and door category.

5. Choose the location or partner territory you want to cover.

6. Apply for the appropriate referral package.

7. Become eligible for suitable homeowner introductions within your selected area.

​

APN is not intended to operate as a mass lead-selling website. It is being developed as a curated network of suitable residential contractors, installers, consultants and home-improvement specialists positioned by service category and territory.

How APN Double Glazing Referrals Work

 

Homeowners visit APN Double Glazing when researching projects such as:

​

• Replacement windows

• UPVC windows

• Aluminium windows

• Timber windows

• Double glazing

• Window repairs

• Composite doors

• Front and back doors

• French doors

• Bifold doors

• Sliding patio doors

• Heritage windows

• Conservation-area windows

• Listed-building windows

​

Where a homeowner requests a quotation or asks to be connected with a local installer, the enquiry can be considered for referral to an appropriate APN partner.

​

Matching may take account of:

​

• The homeowner’s location

• The installer’s selected territory

• The type of windows or doors required

• The installer’s approved category

• Specialist experience

• Installer capacity

• Membership level

• Territory availability

• The requirements of the individual project

​

The purpose of the network is to introduce relevant homeowner enquiries to suitable professional businesses rather than distribute every enquiry indiscriminately.

​

​

Step 1: Register with the Architectural Partner Network

 

The first step is to register your business with the Architectural Partner Network.

​

The application should provide accurate information about your company, including:

​

• Business name

• Trading address

• Contact details

• Website

• Years in business

• Window and door services offered

• Areas covered

• Relevant registrations

• Insurance

• Guarantees

• Recent experience

• Customer reviews

​

APN is a curated network rather than an open directory. Applications are therefore subject to suitability, category fit and verification.

​

Registering an interest does not automatically guarantee acceptance, a territory or future referrals.

​

​

Step 2: Become an APN Verified Member

 

APN Verified Membership is the entry point into the Architectural Partner Network.

​

Approved Verified Members may receive:

​

• APN Verified Member status

• A professional APN profile page

• Use of the APN Verified Partner badge

• Category and service presentation

• Greater professional credibility

• Profile visibility within the network

• A route towards future referral membership

​

Verified status is intended to help suitable window and door companies demonstrate that they have completed the APN membership and verification process.

​

The badge may be used, subject to APN rules, on appropriate business materials such as:

​

• Websites

• Quotations

• Email signatures

• Brochures

• Social-media profiles

• Vehicle graphics

• Marketing literature

​

Verified Membership itself is primarily concerned with professional status, profile visibility and preparation for wider APN opportunities. It does not by itself guarantee homeowner leads.

​

​

Step 3: Select Your Window and Door Category

 

Applicants should identify the services they genuinely provide.

​

Relevant APN Double Glazing categories may include:

​

• Double glazing installation

• Replacement windows

• UPVC windows

• Aluminium windows

• Timber windows

• Sliding sash windows

• Flush casement windows

• Window repairs

• Replacement sealed units

• Composite doors

• Aluminium doors

• Timber doors

• French doors

• Bifold doors

• Sliding doors

• Heritage windows

• Conservation-area windows

• Listed-building windows

• Commercial glazing

​

Accurate category selection helps APN identify which businesses may be suitable for each homeowner enquiry.

​

A company should not select specialist categories unless it has the experience, products and ability to undertake that work properly.

​

​

Step 4: Choose Your Location or APN Territory

 

APN partners are positioned by defined locations and territories.

​

A double glazing company may wish to cover:

​

• A single town

• A city

• Several neighbouring towns

• A London borough or group of boroughs

• A county area

• A wider regional zone

​

Territory selection is intended to help APN organise local coverage and match enquiries with businesses that genuinely serve the relevant area.

​

Applicants should choose territories they can cover reliably rather than selecting large areas that cannot be serviced effectively.

​

Territory availability may depend on:

​

• The window and door category

• Existing partner coverage

• Membership package

• Local homeowner demand

• The number of suitable applicants

• The company’s operational capacity

• APN’s wider network requirements

​

Some locations and categories may be more competitive than others.

​

APN’s territory structure is designed to avoid an unrestricted directory model and provide a clearer route to local profile positioning and homeowner introductions.

​

​

Step 5: Apply for Referral Partner Status

 

Businesses that want to receive suitable homeowner introductions will need to progress beyond basic Verified Membership into the relevant APN referral route.

​

The Architectural Partner Network is structured around four principal membership levels:

​

APN Verified Member

The entry-level route for profile visibility, verification, badge use and professional credibility.

​

APN Referral Partner

For approved businesses seeking eligibility for suitable homeowner introductions within an agreed category and territory.

​

APN Growth Partner

For established businesses seeking stronger category visibility, enhanced profile positioning and greater involvement within the network.

​

APN Priority Partner

A more selective route for suitable businesses seeking stronger positioning within valuable or competitive categories and territories.

​

Window and door businesses seeking homeowner referrals are likely to require Referral Partner, Growth Partner or Priority Partner status, depending on the territory, category and level of positioning required.

​

Referral Partner status is expected to be available from January 2027 and will be subject to approval, suitability, category availability and territory availability.

​

​

Suitable Businesses for the Network

 

The APN Installer Network may be suitable for:

​

• Independent window fitters

• Local double glazing companies

• Regional window and door businesses

• UPVC window suppliers and installers

• Aluminium window specialists

• Timber window companies

• Window repair companies

• Composite door installers

• Heritage glazing specialists

• Window manufacturers with installation teams

• Established home-improvement companies

• Businesses serving several local territories

​

APN is particularly interested in installers that communicate professionally, provide clear written quotations and respond properly to homeowner enquiries.

​

​

What APN Looks for in Window Installers

 

Applicants may be assessed using information relating to:

​

• Business identity

• Trading history

• Public liability insurance

• Relevant competent-person registration

• Product guarantees

• Workmanship guarantees

• Customer reviews

• Installation experience

• Complaint-handling procedures

• Professional presentation

• Website quality

• Service areas

• Capacity to respond to referrals

• Specialist product knowledge

​

Verification is intended to improve confidence and help distinguish suitable APN members from businesses appearing in an unrestricted trade directory.

​

It does not remove the installer’s responsibility for its own advice, contracts, products or work.

​

​

Why Secure a Territory Early?

 

Window installation is a competitive category, particularly in larger cities and areas with strong homeowner demand.

​

Applying early may help a suitable company:

​

• Establish APN Verified status

• Build its professional profile

• Select relevant service categories

• Express interest in preferred territories

• Prepare for the referral launch

• Avoid missing out where category or territory availability becomes limited

• Strengthen its position before wider homeowner introductions begin

​

APN states that early Verified Members will be better positioned to secure their category and territory before the wider referral platform opens.

​

​

What Types of Referrals Could Be Available?

 

Potential APN Double Glazing enquiries may include:

​

• One or two replacement windows

• Full-house window replacement

• Misted double-glazed units

• Window repair enquiries

• New UPVC windows

• Aluminium window projects

• Timber window replacement

• Composite front doors

• New back doors

• Bifold door installations

• Sliding-door installations

• French doors

• Windows for extensions

• Windows for property renovations

• Conservation-area projects

• Listed-building window projects

• Planning-related window enquiries

​

The value, scale and suitability of individual enquiries will vary.

​

APN cannot guarantee a fixed number of leads, appointments, quotations, project values or completed installations. Referral membership provides eligibility for suitable introductions where available; it is not a guarantee of work or return on investment.

​

​

A More Professional Alternative to Mass Lead Platforms

 

APN is not designed around selling the same enquiry to a large and unrestricted number of companies.

​

The network is based on:

​

• Verified membership

• Professional profiles

• Defined categories

• Selected territories

• Referral eligibility

• Homeowner project requirements

• Suitable local matching

• Professional business presentation

​

This structure is intended to give homeowners a more organised route to suitable companies while helping credible installers strengthen their market position.

​

​

Expectations When Receiving a Referral

 

APN partners receiving a homeowner introduction should respond professionally.

​

Installers should aim to:

​

• Contact the homeowner promptly

• Clearly identify their business

• Refer to the project details supplied

• Confirm that they cover the location

• Ask relevant questions

• Arrange surveys professionally

• Provide clear written quotations

• Explain products and specifications properly

• Avoid excessive sales pressure

• Respect requests not to be contacted further

• Provide suitable aftercare

​

A referral is an opportunity to discuss and quote for a project. It is not a confirmed instruction.

​

The homeowner remains free to compare companies and decide whether to proceed.

​

​

Independent Installer Contracts

 

All companies participating in the Architectural Partner Network remain independent businesses.

​

Any contract for:

​

• Surveying

• Measuring

• Manufacturing

• Supplying

• Installing

• Repairing

• Guaranteeing windows or doors

​

is made directly between the installer and the homeowner.

​

APN Double Glazing, APN Home Limited and the Architectural Partner Network do not become the installation contractor merely because an enquiry has been introduced through the network.

​

The appointed installer remains responsible for:

​

• Site surveys

• Accurate measurements

• Product recommendations

• Quotations

• Contracts

• Deposits and payments

• Regulatory compliance

• Installation

• Workmanship

• Certification

• Guarantees

• Complaints

• Aftercare

​

​
