Renovation Contractor in Romford

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.

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.

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.

Hold back 10-15% of the contract value for surprises on a standard renovation, and 20% for older properties where opening walls tends to reveal outdated wiring, corroded pipes, or damp. Do not tell the contractor your contingency figure — it is your buffer, not extra scope budget.

Ask: who will actually be on site daily (the owner or a foreman), which parts are done by their own team versus subcontractors, how many projects they run at once, what their current lead time in Romford is, how they price variations, and what their warranty covers and for how long. The quality of the answers tells you as much as the answers themselves.

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.
