Frequently Asked Questions for New and Experienced Home Buyers

if you get stuck or need help, feel free to contact us and we’re happy to offer our support that way too.

Before we go ahead answering your question you might also want to have alook at Proficiency's Privacy Policy and Term's & Conditions. Many of the questions you will also find on About us Page.

1. Do you need planning permission

Large projects with a significant impact on your surroundings will require planning permissions from your local authorities before any work commences. This includes extensions, renovations, basement and loft conversions.However, if your project will have no impact on your neighbours or local environment, it may be considered a ‘permitted development’, meaning you will not need planning permission. Proficiency is able to advise you on projects that need planning permissions and assist you with the paperwork.

2. Do you need an architect

It is recommended to work with an established building company instead of simply working with a builder. An established company is able to guarantee you high quality work, proof of quality work from previous projects and a warranty for a reasonable period of time. Working with a builder might be cheaper at the moment but ultimately expensive since you may constantly require repairs.

3. Do you need an interior designer

You will need an interior designer to handle interior finishes such as colour schemes, fixtures,furniture, lighting and decor. If you already have an idea of the design in mind, an experienced interior designer can help you select what will exclusively work for your project based on your budget and preferences.

4. How much is it going to cost me

A house extension can cost you anywhere between £16,000 to £100,000.Loft conversions cost between £35,000 to £70,000. House renovation costs £38,000 to £74,000 or £1000-£2000 per square metre. House refurbishment costs £460-907 per square metre.

The cost of any project depends on the location, type of project, complexity of design, labour costs, materials used, building regulations, quality of work and additional costs such as 20% VAT.

5. How soon can you start my project

Your project can start within 8 weeks of contacting us. This is the planning period. We will first conduct a feasibility study, then meet with you at your preferred time to discuss the scope of the project. Planning permission is obtained during this time. Planning drawings, 3-D renders, party wall agreements, building regulation drawings and structural drawings are also put together where necessary.

6. Do you provide warranty for my project

Proficiency provides a 15 Year structural guarantee on all structural projects. We are confident in the quality of our craftsmanship.

7. How long is it going to take to complete my project

A project can take anywhere between 1 month to a year or more depending on the scope of work and the type of project. On average, loft conversions take 6-10 weeks to complete. Basement conversions take between 8 to 20 weeks. Renovations, extensions and refurbishment take 6 months on average. New builds usually take 5 months to a year depending on the size of the project and the planning required.
