Vin-Dec manages your project from the first meeting to handover. We arrange the architect, structural engineer, planning, party wall agreements and building control, so you do not have to.

From first meeting to start on site

  1. We meet you to go through the project and understand what you need.
  2. We arrange an architect to visit and design the new layout, and submit the drawings for planning approval if needed.
  3. If structural work is involved, we arrange a structural engineer to supply the drawings.
  4. We work out the cost and give you a written quotation, which forms part of the contract.
  5. We start work on a date agreed with you.

What is included

Our quotation covers the building work and everything we can include in-house. Architect, planning, structural engineer and building control fees are charged on top, but we arrange all of them for you, so you do not need to deal with them yourself.

Yes. We arrange the architect, planning application, structural engineer, party wall agreements and building control as part of the project.

How long it takes

As a guide: a loft conversion takes 2 to 3 months, an extension 3 to 4 months, and a full house refurbishment with a loft conversion and extension 9 to 12 months. Timescales vary with the complexity of the job and the weather.

As of November 2026 our lead time is around six months, though we can sometimes start sooner depending on the project.

Payments

A small deposit, then stage payments as the work progresses, with a three-month retention.

Insurance and guarantees

Yes. We carry £5 million public liability and £10 million employer's liability insurance, plus contract works insurance that covers materials on site.

Our workmanship is guaranteed for 12 months as standard, which can be extended to 24 months depending on the project. We can also arrange an extended warranty of up to 10 years. Windows and doors from specialist suppliers carry their manufacturers' 5 to 10-year warranties.

Yes. Electrical work is carried out by NICEIC-registered electricians and gas work by Gas Safe-registered engineers.
