Frequently asked questions

When hiring extension builders in Kent, look for those who are fully insured and hold relevant trade qualifications, such as NVQs or SVQs in Construction.

They should also hold a Construction Skills Certification (CSCS) card, which proves they’re trained and qualified to perform their work safely on your construction site.

Memberships with the Federation of Master Builders and other accreditations from recognised industry bodies are further proof of their experience and quality.

Reputable house extension builders should also have experience in carrying out planning applications and understanding building regulations, ensuring your project runs smoothly.

The timescale for an extension varies depending on the size and complexity of the project. A small single-storey extension might take 8 to 12 weeks, while larger double-storey extensions could run to several months.

Local extension builders in Kent will usually provide an estimated timeline alongside their quote so you can plan accordingly. You may want to keep this in mind when reviewing how much extension builders cost; extensions are big disruptions, and a quicker process is always valuable.

To find reliable Kent extension builders, here’s what you can do:

  • Check for positive customer reviews and high ratings

  • Review examples of previous work (ideally before-and-after photos)

  • Ask for references

  • Ask for written, detailed home extension quotes that include all costs, clear schedule, and service terms

  • Verify whether extension builders belong to any reputable industry bodies, such as the Federation of Master Builders (FMB)

Ask for evidence of relevant insurance, such as public liability insurance and professional indemnity insurance coverage

Remember, builders are not technically required to hold a formal licence to operate, but certain certifications do demonstrate compliance and competence, such as:

  • NVQs in Construction

  • CSCS card

  • Specialist licences (such as Part-P certification for electrical installations)

If any extension builders in Kent are unwilling to show proof of their qualifications, credentials, or examples of previous work, it’s best to move ahead with other options.

A detailed quote from any home extension builder in Kent should cover the following:

  • Labour costs

  • Material costs

  • Subcontractor costs (such as electricians or plumbers)

  • Project management costs

  • Planning application costs

  • VAT (if applicable)

Quotes should also outline timescales, service terms, and any other potential extra charges. Exactly what’s included depends on the scope and complexity of your proposed project. For example, some projects may include groundwork costs, others may not.

Comparing itemised quotes from several house extension builders in Kent will help you understand where your money is going and get you the best value for money.

Like with other house renovation costs, how much extension builders cost will depend on several factors. Here are the main influences on the cost of your home extension:

  • Size of the extension

  • Type of materials used

  • Whether it’s single or double storey

  • Complexity of the design

There are several other possible factors, such as ground condition, planning requirements, and the finishes you choose, that will influence the final price.

While you can use a construction cost calculator to help work things out, you’ll need a good understanding of your budget, your preferences, and the current market rates to prioritise what you want and get a clear picture of what’s possible for your project.
