Frequently Asked Questions – Home Extensions
Q1. Are Building Regulations necessary to adhere to when building an extension?
A1. The simple answer here is Yes – However, when building a conservatory or a porch that has been built up from the ground and is within 6 metres of the main dwelling, in this situation it is not necessary and this type of extension is in fact exempt, just as long as the necessary glazing regulations are adhered too within the safety glazing requirements as detailed in (Part K), with the thermal separation from the main dwelling has been maintained and the space has independent heating. It is important to speak to a Building Control Surveyor for further information on safety glazing aspect. Choosing a Fensa certified installer is the best option.
It is further, advisable to endeavour to ensure that a conservatory is not constructed causing restricted ladder access to windows serving as a room in the roof or a loft conversion, especially if in the scenario that window is needed as a means of emergency escape in case of fire in the property.
Q2. What are Building Regulations?
A2. Are a list of requirements (referred to as Schedule 1) that are designed to ensure that minimum standards for health, safety, welfare, convenience, energy efficiency, sustainability and to prevent misuse, abuse or contamination of water supplies are all adhered too.

The possibility the fire precautions would be affected, either inside or outside the building again potentially making the dwelling unsafe.
Or affecting the access and facilities for disabled people.
If building regulations do apply all the contracted work carried out must comply with the appropriate regulations stated.
Q4. What is the competent persons scheme?
A4. (CPS) has been specifically brought in by the UK government to ensure that individuals and organisations carrying out work are able to elf certify that their alternations comply fully with Building Regulations as dictated by UK Law. This has been developed as an alternative to submitting building notice or having an external inspector approve the work carried out.
A5. What is an approved inspector?
A5. With the building control process being deregulated it isn’t necessary to get your home extension project inspected by the local council buildings control department. As there are specialist professionals who are approved of by the government who will be available to ensure the project will meet all appropriate government related building regulations.
Q6. Is approval needed for any electrical work?
A6. Yes- To ensure the safety of inhabitants of houses and flats the Part P Regulations have been introduced concerning electrical work, 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.
These rules have been introduced to ensure the following:
Reduction in the number of deaths, injuries and fires caused by faulty electrical installations
preventing cowboy builders leaving electrical installations in an unsafe condition
As, if the building regulations are not followed:
electrical work undertaken may not be safe
There may be difficulty selling your home if the correct certification is not in your possession.
The regulating body may insist that the faulty work be put right.
