What building services do Best Builders offer?

Best Builders provide a full range of residential and commercial building services, including house extensions, loft conversions, kitchen and bathroom installations, full refurbishments, structural alterations, bespoke joinery and general building and maintenance. All work is fully project managed from initial consultation through to final handover.

Do you offer free quotes for building and renovation projects?

Yes. We offer a free, no-obligation consultation and quotation for all building, renovation and refurbishment projects. After discussing your requirements and budget, we provide a clear written quote outlining the proposed work, timelines and costs so you can make an informed decision before committing.

Are you fully insured and accredited builders?

We are fully insured and work to current UK building regulations and industry standards. Our qualified tradespeople and site managers follow strict health and safety procedures, and we can work closely with building control, structural engineers and architects where required to ensure your project is compliant and completed to a high standard.

Can you manage the whole building project from design to completion?

Yes. We offer a complete design-and-build service. This can include initial feasibility advice, help with planning permission and building regulations, detailed quotations, scheduling trades, sourcing materials, coordinating inspections and keeping you updated throughout the build until final completion and sign-off. This end-to-end approach reduces stress and helps keep your project on time and on budget.

How long does a typical house extension or renovation take?

Timescales depend on the size and complexity of the project, but as a guide, smaller refurbishments may take a few weeks, while larger house extensions and full renovations can take several months. During the quotation stage we provide an estimated schedule, then confirm start dates and key milestones before work begins so you know what to expect.

Do you help with planning permission and building regulations?

We can advise on whether your project is likely to require planning permission or fall under permitted development. Where formal consent is needed, we can work with you and your architect to prepare plans and documentation, liaise with the local authority and coordinate any required inspections to ensure your project meets all relevant building regulations.

Can you work around us while we are living in the property?

In many cases we can carry out building and refurbishment work while you remain in the property. We plan the project to minimise disruption, keep work areas as contained and tidy as possible, and maintain clear access routes. For more disruptive phases we will discuss options with you in advance so you can plan accordingly.

Let us know a few details about your project, budget and timescale, and we will arrange a convenient time for a site visit or consultation. After this we provide a detailed written quote and, if you are happy to proceed, schedule a start date for the works.
