Renovation Contractor in Brighton

A variation is any change to the agreed scope after signing — moving a wall, upgrading tiles, fixing a hidden problem. Insist every variation is priced and approved in writing before the work happens. Most renovation budget blowouts are not the original quote being wrong; they are dozens of verbally-approved variations nobody tracked.

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.

Manage trades yourself only if the job involves one or two trades and you can be on site regularly. Once a project needs sequencing (demolition, then rough plumbing and wiring, then walls, then finishes), a contractor typically saves more in avoided rework and delays than their 10-20% management margin costs.

Usually yes for single-room projects if water and power stay connected to the rest of the home; usually no for whole-home work involving dust-heavy demolition or when the only kitchen or bathroom is out of service for weeks. Ask the contractor to phase the works so one bathroom stays functional, and budget for short-term accommodation on gut renovations.

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.

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.
