Quick answer — TL;DR

Timber sash and heritage window jobs stall because consent, drawings, joinery details and the conditions attached to an approval are handled by email between the homeowner, their agent, the council and your workshop, with nobody tracking the whole chain. We build a job tracker that records what consent route the homeowner's advisers have identified, holds each drawing revision and submission, tracks conditions such as sample approval, and releases the joinery order only when the conditions your team lists are met.

Drawings approved, sample still outstanding

The homeowner lives in a listed Georgian terrace and wants their rotten sashes replaced like for like. Their heritage consultant submitted the application with your joinery drawings. Consent came through with a condition: a sample of the glazing bar profile and the paint colour to be approved before work starts. The consent letter went to the consultant. Your workshop, not knowing about the condition, started making the sashes.

Now the joinery is half made and the conservation officer has not seen a sample. Everyone is waiting, and your bench space is tied up.

Why heritage jobs are hard to follow

A sash window job in a listed building or conservation area can involve the homeowner, a consultant or architect, the council's conservation officer, your surveyor, your drawing office and your workshop. Each produces documents at different times, and conditions can change what you are allowed to make.

  • Nobody lists, per job, the consent route and what it requires.
  • Joinery drawings go through several revisions with no record of which was submitted.
  • Consent letters and conditions go to the homeowner's agent, not to you.
  • Conditions, such as samples or details to approve, are not tracked to discharge.
  • The workshop starts work from the latest drawing without knowing whether it is approved.

Whether a job needs consent, and what an approval permits, is for the homeowner, their advisers and the council. We track what they tell you.

Workshop time spent on joinery that then has to change is expensive and hard to recover. Jobs that stall hold up your workshop programme and your fitting teams. Homeowners who have waited months for consent get frustrated with everyone involved, including you. And starting work before conditions are discharged can create problems for the homeowner that you do not want to be part of.

  1. Each job records the consent route identified by the homeowner or their agent, with the agent's contact and the council reference once submitted.
  2. Joinery drawings are stored as numbered revisions, and the revision submitted with the application is marked.
  3. The consent decision and each condition are recorded, with who must act and what evidence is needed, such as a sample, a profile section or a paint specification.
  4. Reminders go to the right person as each condition waits, and the homeowner and agent see a simple status page.
  5. The workshop order stays on hold until your team marks the conditions it has listed as met, with a manager override recorded if used.
  6. Final drawings, consent documents and condition discharge letters stay on the job for the homeowner's records.

What the workshop and office gain

Your workshop only starts joinery that is cleared to go, and makes it from the approved drawing. The office sees every heritage job, what it is waiting on and for how long. Agents and homeowners know where things stand without ringing. And the record of drawings, consents and conditions stays together for the life of the building.

The same tracker also suits jobs in conservation areas where the council has specific expectations about materials or glazing patterns, even where the route is simpler.

Signs your heritage jobs need tracking

  • Joinery has started before conditions were met.
  • You are not sure which drawing revision was submitted.
  • Consent letters reach you late, through the homeowner.
  • Heritage jobs sit for months without anyone chasing.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Will the tracker tell us whether consent is needed?

No. The homeowner and their advisers establish that with the council. The tracker records the route and follows it through.

Can homeowners and agents see progress?

Yes, through a simple status page for their job, without needing an account.

Does it work for timber casements and doors too?

Yes. Any consent-led joinery job follows the same stages.

What affects the cost?

How drawings are produced today, how your workshop is scheduled, and how many parties need their own view.
