Renovation Contractor in Watford

A single-room refresh typically takes 1-3 weeks, a kitchen or bathroom 2-6 weeks, and a whole-home renovation 2-6 months depending on structural work and approvals. Add lead time before the start date for permits, custom cabinetry, and contractor availability — good contractors are often booked 1-3 months out.

Payments should follow completed milestones, not calendar dates: for example deposit, completion of demolition and first-fix (rough-in), completion of second-fix and finishes, then a final payment of 5-10% held until the snag list (punch list) is closed. That final retention is your only real leverage for defect fixes.

For most markets 10% or less of the contract value is a reasonable deposit, sometimes up to 20-30% for jobs with heavy upfront material orders like custom cabinetry. Several countries cap deposits by law. Never pay a large share of the total before work starts, and never pay the full amount up front.

At minimum: full scope of works, itemized price, start and completion dates, payment schedule tied to milestones, who obtains permits, how variations are priced and approved in writing, warranty terms, and how disputes are handled. If a contractor resists putting these in writing, that is the answer to whether you should hire them.

Ask every contractor to break the quote into the same line items: demolition, structural, plumbing, electrical, walls and finishes, fixtures, and a stated allowance for materials you choose. Then compare line by line. A single lump-sum number cannot be compared and cannot be enforced when scope questions come up mid-project.

General builder day rates typically run £200-£320 per day outside London and £300-£450 in London and the South East. Most renovation work is quoted as a fixed project price rather than day rate — Checkatrade cost guides put a full house refurbishment at roughly £800-£2,500 per square metre depending on spec.

They are separate systems. Most internal renovations need no planning permission, but structural work, new drainage, electrics, and replacement windows must comply with Building Regulations and get signed off. Extensions and external changes may need planning permission too — check with your local authority before committing to a design.
