Frequently asked questions for building regulations

Jigsaw • 1 May 2022

Building control helps ensure that all building work carried out meets Building Regulations . These are the standards, supported by Approved Documents, set out to protect the health and safety of people within built environments. Meeting these requirements is the responsibility of the persons undertaking the building work and the owner of the building. Subsequently all building work must be independently verified to certify all Building Regulations have been successfully met.

As a property maintenance and construction company, our seasoned builders and installers are often questioned about building regulations. As such, we have put together this list of frequently asked questions. If you are looking to have an extension built or to amend the layout of your property, we hope you will find this useful.

Q. What does a building control inspector check on site?

A . Every project is different, but regardless of the level of complexity involved on any given site, the role of a building control inspector is to check that all aspects of construction comply with the regulations. They will inspect foundations, structural issues, damp-proofing, heating and ventilation, drainage and sanitation, accessibility, fire protection and more. Building control teams consult with building owners, developers and designers on the design and specifications of buildings often before any construction work begins. As building work progresses, inspections will be carried out at various stages in the development in order to check completed work.

Q. Who can I use for my building control?

A. In England and Wales, you can use either a local authority or an approved inspector. Approved inspectors are private companies that are registered by the , Construction Industry Council Approved Inspector Register (CICAIR) on behalf of the English and Welsh Governments to check building work complies with regulations. If you choose an approved inspector for your project, they must inform the local authority by submitting an initial notice.

Q. I want to build an extension to my home, do Building Regulations apply?

A. Yes - but a porch or conservatory built at ground level and under 30 sq.m in floor area is exempt, provided that the glazing complies with the safety glazing requirements of the Building Regulations (Part K) and thermal separation from the main dwelling is maintained and the space has independent heating.

You can speak to a Building Control Surveyor for further information on safety glazing etc. It is advisable to ensure that a conservatory is not constructed so that it restricts ladder access to windows serving a room in the roof or a loft conversion, particularly if that window is needed as a means of emergency escape in case of fire.

Q. I want to build a garage extension attached to my home; do Building Regulations apply?

A. Yes - but a car port extension, open on at least two sides and under 30 sq.m. in floor area, is exempt. You should ensure a car port does not interfere with the proper working of a low-level flue from an oil or gas appliance.

Q. I want to build a detached garage under 30 sq.m. in floor area, do Building Regulations apply?

A. No - the building will be exempt from the regulations providing it is: -

under 30 sq.m. in floor area.
single storey and does not contain any sleeping accommodation.
built substantially of non-combustible materials or built at least 1m from any boundary.

Q. Will the Building Regulations apply to an internal alteration within my home or other type of building?

A. Yes- very likely. The regulations specify what forms of alteration amount to ‘material alteration’ and are therefore ‘Building Work’, taking account of the potential for the proposed work to adversely affect compliance of the building with specific requirements.

On this basis the regulations are very likely to apply if your project:

will involve alterations to the structure of the building (for example, the removal or part removal of a load bearing wall, joist, beam or chimney breast)
will affect escape or other fire precautions, either inside or outside the building
will affect access or facilities for disabled people.

On the assumption that the regulations do apply, all the work involved in the alteration must comply with all the appropriate requirements.

Q. Do I need approval for Electrical Work?

A. The Part P Regulations concerning electrical work apply mainly to dwelling houses and flats, including new circuits serving gardens, outbuildings such as sheds, detached garages and greenhouses. The design and installation of electrical installations associated with these dwellings falls under the Building Regulations.

The rules have been introduced to:

reduce the number of deaths, injuries and fires caused by faulty electrical installations
prevent cowboy builders leaving electrical installations in an unsafe condition

If you do not follow the Building Regulations:

electrical work undertaken may not be safe
you may have difficulty selling your home if you are not in possession of the correct certificates
we may insist you put right faulty work

Q. Why should I use an installer who is registered with a competent person scheme?

View the competent person register (external link) for more information.

Members of schemes can deal with all the new rules for you
Members are qualified to carry out electrical work
Members will give you a certificate to confirm their work follows the new rules
You will not have to pay Building Control charges
You will have the option of taking out an insurance-backed guarantee for the work
You will have access to a formal complaints procedure if you are not happy with the work.

Q. What happens if work is found to contravene the Building Regulations?

If a person carrying out building work contravenes the Building Regulations, the local authority or another person may decide to take them to the magistrates' court where they could be fined for the contravention, and a further daily fine for each day the contravention continues after conviction.

This action (under section 35 of the Building Act 1984) will usually be taken against the builder or main contractor and proceedings should be taken within six months of the offence. Alternatively, or in addition, the local authority may serve an enforcement notice on the owner requiring them to alter or remove work which contravenes the regulations. If the owner does not comply with the notice the local authority has the power to undertake the work itself and recover the costs from the owner.

Which Renovations will add the most value to your property

by Lisa Woolnough • 1 May 2025

Which Renovations will add the most value to your property When thinking about renovations that significantly increase your property's value, it's important to concentrate on upgrades that improve functionality, aesthetics, and energy efficiency. Here are some top renovations to consider: 1. Kitchen Remodel  The kitchen is often the heart of the home, and updating it can offer a substantial return on investment. Consider modern appliances, energy-efficient fixtures, and a layout that maximises space. Features like a kitchen island or high-quality countertops can also make a significant impact. 2. Bathroom Upgrades  Renovating bathrooms is another excellent way to increase your property's value. Add double vanities, walk-in showers, or even a soaking tub. Opt for timeless designs and durable materials that appeal to many potential buyers. 3. Open-Plan Living  Modern buyers often prefer open, airy spaces. Knocking down non-structural walls to create an open-plan living area can make your home feel larger and more welcoming. This renovation can dramatically transform the space without major structural changes. 4. Energy-Efficient Improvements  Installing energy-efficient windows, doors, and insulation can lower utility bills and make your home more attractive to eco-conscious buyers. Consider adding solar panels or smart home technologies for additional appeal. 5. Curb Appeal Enhancements  First impressions matter. Updating the exterior with a fresh coat of paint, new cladding, or a modern front door can significantly boost your home's curb appeal. Landscaping improvements, such as adding flower beds or a well-maintained lawn, can also make a big difference. 6. Basement or Loft Conversion  Converting an unused basement or loft into a functional living space, like a home office, gym, or extra bedroom, can add valuable square footage to your home, making it more appealing to buyers who need additional space. 7. Deck or Patio Addition  Outdoor living spaces have become increasingly popular. Adding a deck or patio can create an inviting area for relaxation and entertainment, extending your living space and enhancing your home's appeal. 8. Smart Home Integration  Incorporating smart home features such as automated lighting, security systems, or thermostats can make your property more attractive to tech-savvy buyers. These upgrades not only offer convenience but can also improve energy efficiency. 9. Roof Replacement  A new, durable roof can enhance the aesthetic appeal of your home and provide peace of mind to potential buyers. A well-maintained roof signifies a well-cared-for home, which can be a significant selling point. 10. Garage Door Replacement  Replacing an old garage door with a new, stylish, and energy-efficient model can improve the overall look of your home and provide a great return on your investment. By strategically planning these renovations, you can maximise the value of your property and ensure it stands out in the competitive real estate market. Consider your budget and the preferences of potential buyers in your area to make the most informed decisions.

Is it Worth Knocking Through for a Kitchen-Diner?

by Lisa Woolnough • 14 April 2025

Is it Worth Knocking Through for a Kitchen-Diner? Creating an open-plan kitchen-diner is one of the most popular home improvements in the UK. Many homeowners are choosing to knock through walls to combine their kitchen and dining area into one large, social space. But is it worth it? In this blog, we’ll explore the benefits, costs, potential challenges, and the latest design trends to help you decide if a knock-through is the right choice for your home. The Benefits of a Kitchen-Diner Knock-Through More Space & Better Flow Removing a wall between the kitchen and dining room can create a more spacious, open plan feel, making your home feel larger and more inviting. Brighter Living Area Traditional kitchens can sometimes feel dark and enclosed. Knocking through allows natural light to flow freely, creating a brighter and more pleasant living space. Better for Entertaining A kitchen-diner makes it easier to cook and chat with guests at the same time, making it perfect for dinner parties and family gatherings. Increased Property Value Open-plan living is highly desirable for buyers. A well-executed kitchen-diner conversion can add value to your home and make it more appealing to potential buyers. More Functional Living Space A combined kitchen and dining area can create a more practical, multifunctional space that suits modern family life. Current Trends for Kitchen-Diners If you're considering knocking through, thekitchn.com has some of the latest trends to incorporate into your design. These include: Moody Hues & Cool Metals Rich, deep colours like navy, plum, and burgundy, combined with sleek metals like chrome and polished nickel, are making a bold statement in modern kitchens. Concealed Kitchens Seamless cabinetry and integrated appliances create a sleek, minimalist look, making your kitchen feel more like part of the living space. Natural Materials & Warm Woods Sustainable materials like stone and warm wood finishes bring a timeless, cosy feel to open-plan kitchen-diners. Multi-Zoned Layouts Kitchens are now designed with dedicated areas for cooking, entertaining, working, and relaxing, ensuring a functional and organised space. Bold Colours & Mixed Materials Combining soft and bold colours like sage green, dusty pink, and rich browns with organic textures adds depth and warmth to the design. Open Shelving & Display Areas Stylish open shelving provides both storage and a way to showcase personal style, keeping the space practical yet decorative. Interesting Lighting Statement lighting fixtures made of coloured glass, thick metals, or natural materials serve as focal points in modern kitchen-diner spaces. Retro Influences Vintage elements such as patterned wallpaper and colourful area rugs are making a comeback, blending nostalgia with contemporary design. Sculleries & Secondary Kitchens More homeowners are incorporating secondary kitchen spaces or sculleries to keep the main kitchen clutter-free. Wellness-Focused Design Biophilic elements like indoor plants, natural light, and calming colour schemes are being used to create a healthier, more inviting kitchen environment. Considerations Before Knocking Through Is the Wall Load Bearing? If the wall is structural, you’ll need a steel beam (RSJ) to support the weight of the upper floors. A structural engineer’s assessment is essential before proceeding. Building Regulations & Permissions Most internal wall removals don’t need planning permission but must comply with Building Regulations. Your builder should notify your local authority or work with a building control inspector. Budget & Costs The cost of a knock-through varies depending on whether the wall is load-bearing, whether you need to relocate plumbing or electrics, and the level of finish you require. On average, expect to pay between £2,000 and £5,000 for a standard knock-through. Disruption & Mess Removing a wall is a major job that will cause dust and noise. Be prepared for some inconvenience while the work is being carried out. Heating & Ventilation Open-plan spaces can be harder to heat and may require additional heating solutions, such as underfloor heating or a more powerful radiator. Is a Kitchen-Diner Knock-Through Worth It? For many homeowners, the benefits of a larger, brighter, and more social space far outweigh the costs and temporary disruption. If you’re planning a knock-through, working with an experienced builder and structural engineer will ensure a smooth process with great results. At Jigsaw Construction Surrey, we manage your project from start to finish and keep you fully informed along the way. We can arrange both an architect and structural engineer who we work with regularly to help smooth this process for you.
