Q1 What are the Building Regulations?
The Building Regulations are levels of performance laid down by
Parliament dealing with the construction of buildings and the installation
of some services. The regulations cover a comprehensive range of
requirements including issues such as structural stability, fire safety,
moisture resistance, saving energy and making buildings suitable for
disabled people. Return to top
Q2 Who enforces the Building Regulations?
The Building Control Surveyor checks plans for compliance with
Building Regulations and carries out inspections of work on site as it
progresses. Ultimately, and where appropriate, formal enforcement is
carried out by the Local Authority through the Courts on the evidence of
the Building Control Surveyor. However, this is extremely rare as the
emphasis of the service is about working together with applicants to
find practical cost effective ways of achieving the required minimum
standards of health and safety whilst meeting the aspirations of the
client/designer. Return to top
Q3 What work is subject to Building Regulations?
If you want to put up a new building or extend or alter an existing one,
the Building Regulations will probably apply. They will probably also
apply if you put a building to a differing use. Building Regulations
approval is completely different from Planning Permission and it does
not mean that if you get one you will automatically get the other.

Q4 Is Planning Approval the same as Building Control Approval?
No. Planning deals with issues such as aesthetics, the impact on the
environment, traffic and neighbour notification etc. Building control
is concerned with health and safety issues, energy conservation and
disabled access and use of buildings. Return to top
Q5 Do I need both Planning and Building Control approvals?
In most cases approval is required from both Building Control and
Planning but some minor works may be permitted development
under planning law and/or exempt from Building Regulations. It is
advisable to check with both offices before proceeding. For Building
Control call 0208 547 4699 and for Planning 0208 547 5332.

Q6 When do I need Building Regulation Approval?
(i) Do I need approval to build an extension to my house?
Yes, although the regulations do not apply to some extensions at
ground level with a floor area no bigger than 30 square metres. These
are a conservatory, porch, covered yard or covered way, or a carport
open on at least two sides. However even if a structure itself is
exempt from Building Regulations, fixed electrical installations may
still be subject to control [see Q6 (x)].
Please also note that you should still use safety glass for doors and
windows next to doors and also for any windows with cills less than
800mm above the floor. In addition, for conservatories to be classified
as exempt, at least 75% of the roof and 50% of the walls should be
glazed or translucent and any doors and windows maintained
between the existing house and the conservatory. Please also see
our page on 'Altering or extending your home?'. Return to top
(ii) Do I need approval to convert my loft into a room?
Yes, please see our page on
'Thinking about a Loft Conversion?'. Return to top
(iii) Do I need approval to remove a chimney breast from within my
house?
Yes, unless the chimney breast is being removed in its entirety
and there will be no adverse structural affects. Please see the
London District Surveyor’s Information Sheet on the
'Consents Required Prior to Chimney Breast Removal'.
(iv) Do I need approval to make internal alterations within my
house?
Yes, if the alterations are of a structural nature, involve the removal or
part-removal of a load-bearing element (e.g. wall partition, joist,
beam, chimney breast), or if in altering the house, work is necessary
to maintain the means of escape in case of fire. Return to top
(v) Do I need approval to build a detached garage, shed or similar
structure in my garden?
The regulations do not apply to a single storey building with floor
area no bigger than 30 square metres and no sleeping area such
as a detached garage. The building must also be at least 1 metre
from the boundary of the property or, mostly made of non-combustible
material.
The regulations do not apply to a detached building with a floor area
no bigger than 15 square metres and no sleeping area, for example
a garden shed or greenhouse. However even if a structure itself is
exempt from Building Regulations, fixed electrical installations may
still be subject to control [see Q6 (x)]. Return to top
(vi) Do I need approval to install new windows in my house?
Yes, unless you use a company that is registered under the Fensa
(Fenestration Self-Assessment) Scheme when they are authorised
to self-certify that the work complies with the regulations. The
Council subsequently receives notification from Fensa
after the windows have been installed. Please see the guidance
leaflet produced by the District Surveyors Association on
'Replacement Windows to Existing Dwellings'.
Return to top
(vii) Do I need approval to carry out repairs to my house?
No, if the repairs are of a minor nature and you are replacing
like for like. Yes, if the repair consists of re-roofing or removing
a major part of a wall and rebuilding it or underpinning
a load-bearing wall. Please note that the renovation or replacement
of a "thermal element" e.g. an external wall or roof, will require that
element to conform to the latest standards for thermal insulation.
Return to top
(viii) Do I need approval to convert my house into flats?
Yes.
(ix) Do I need approval to install fittings and appliances within my
house that involve:
(a) The installation or alteration of the position of a WC,
bath, etc?
Yes, but only if the work involves new drainage or plumbing.
(b) The installation or alteration of a heating appliance?
Yes, unless the installer is able to self-certify his or her work
as complying with the regulations. Return to top
(x) Do I need approval to install or replace electrical wiring in my
house?
Yes, most probably. From 1st January 2005, fixed domestic
electrical installations, where the electrical supply is shared with
a dwelling house or flat are controlled by Building Regulations.
In essence, either the work can be self-certified by an electrician
registered with one of the Self-Certification Competent Person
Schemes or application (either full plans or Building Notice) must
be made to the local authority together with the relevant charge.
Where electrical work is dealt with by us, an electrical installation
and test certificate signed by a competent electrician will be
required. Please note that such electrical installations are controlled
even if the structure itself is exempt from Building Regulation
control. Return to top
Q7 What must I do to obtain approval?
If your building work requires Building Regulation approval, there are two
procedures to choose from:
(i) Deposit a Full Plans Application or
(ii) Submit a Building Notice
For a Full Plans application, detailed scaled plans need to be drawn
up showing all constructional details. The Building Notice procedure
is intended for less complex projects that do not involve buildings
where people work. Also Building Notices cannot be used for new
buildings or extensions near, (within 3 metres), or over, public sewers.
In such cases Full Plans must be deposited. Please see our Guidance Note on
Building Over or Near to Sewers. If you are unsure whether
a public sewer runs near to your proposed work please feel free to
contact us and we will check the sewer map that Thames Water
provides. Return to top
Q8 Do I have to pay anything for the services?
Yes. A fee is payable to the Council unless the work is exempt or is solely
to provide access and facilities for the benefit of a disabled person. See
our Guidance Note on Charges or On-line charges calculator .
Return to top
Q9 How quickly will my Building Regulations application be dealt with?
We aim to check all applications within 10 working days of receipt.
If any matters require attention we will usually contact you and provide
you with the opportunity of amending your application and/or of supplying
further information. With Full Plans applications the law requires that we
must issue a formal decision within 5 weeks of receipt or, if we agree,
to extend the statutory time period up to 2 months from receipt. We do
however aim to approve your details just as soon as we have received
the information and have verified that it is satisfactory. Return to top
Q10 Do my neighbours have the right to object to what is proposed in my
building regulations application?
No. However, objections may be raised under separate legislation -
for example, if your proposal is subject to approval under the Planning
Acts. You should also be aware of any obligations under the
Party Wall Act. Return to top
Q11 There is no difference in the total cost between a Full Plans
application and a Building Notice. What will the Council do?
If you use a Full Plans procedure, the Council will check your plans
and consult appropriate authorities, e.g. the Fire and/or Water
Authorities. If your plans comply, you will receive a formal notice
confirming that they have been passed. If the Council are not satisfied,
you may be asked to make amendments or provide more details.
If your plans are rejected, the reasons will be stated in the notice.
By working to approved full plans you can be assured that if you
follow those plans then the work will comply with the regulations.
Inspections of the work will be made as it progresses. If you use the
Building Notice procedure you will not receive a formal approval or
rejection notice as the emphasis of checking is based on site
inspections made during the course of the work. If however we
require further information or a plan, you must still supply the details
requested. With both full plans and a Building Notice, when satisfied
that the work is complete and in accordance with the regulations,
we will issue a Completion Certificate. Return to top
Q12 Where can I obtain information on the standards to which I must
build?
From 'Approved Documents', published by Her Majesty's Stationery
Office, giving practical guidance on meeting the requirements of the
regulations. These documents are also available to view on-line from
the government's Planning Portal Website. However, you are not obliged
to use any particular solution if you prefer to meet the requirements of
the regulations in another way. Return to top
Q13 What can I do if my plans are rejected?
You can resubmit them with amendments to make them comply with
Building Regulations. With any rejection notice we issue a
'resubmission form', which you can simply sign and return together
with your amended plans. Assuming the proposed scheme is
substantially the same, no further plan fee is required. Alternatively,
if you think the decision to reject is not justified, you can refer the matter
to the Department for Communities and Local Government for their
determination. Return to top
Q14 Can you recommend a builder or tradesman?
As an independent checking authority we are unable to recommend
builders or tradesmen. However good advice on finding someone
reliable to carry out work on your home can be found in the step by step
guide published by the Office of Fair Trading:
'Having work done on your home'. Return to top
Q15 I am ready to start work, what should I do?
Once you have submitted a valid Building Notice or Full Plans
application, you can start work at any time, but you must give us two
working days' notice of your intention to do so. If relevant, you or your
builder should tell us when you have:
● Dug the foundations (before you concrete).
● Concreted the foundations.
● Prepared the oversite to the ground floor (before concreting).
● Put in the damp proof course (before you cover it up).
● Put in the foul water drainage (before you backfill it).
● Put in the surface water drainage (before you backfill it); and
● Completed the work.
The inspections listed above will not always be relevant for every job.
For example with loft conversions we will usually need to inspect the
structural supports before they are covered up. Please visit our web
page 'Book an Inspection' or for further detailed advice please speak
to the Building Control Surveyor dealing with your proposals.
Return to top
Q16 Can I start work without Building Control Approval?
No - If you have not submitted an application. Yes - Once the
application is submitted you can go ahead and commence work even
if an approval (if applicable) has not been issued. However, you
must ensure that all relevant works are inspected and agreed by the
Building Control Surveyor. Return to top
Q17 What happens once my work is finished?
Please contact us to arrange a final inspection when your work is
finished. Do not make the final payment to your builders until we have
carried out our last inspection. We will give you a Completion Certificate
when we have checked the work meets the required standards. This is
an important document that should be kept safely as it will be required
by solicitors when the property is sold. Return to top
Q18 What happens if I do work without approval?
The Council has to see that building work complies with regulations.
If the work does not comply, you may be asked to alter or remove it.
If you fail to do this, the Council may serve a notice under Section 36
of the Building Act 1984 requiring you to do so. The Council also
provides information about Building Control applications to people
undertaking Land Search enquiries. Therefore any work carried out
without the benefit of Building Control approval, usually evidenced by a
Building Regulations Completion Certificate, is very likely to prevent
the sale of the property. Return to top
Q19 Are there penalties for contravening Building Regulations?
Yes. The Council can commence proceedings, which may lead to a
fine. Please see the Royal Borough's Building Control
Enforcement Policy. Return to top
Q20 How long does the Council have to take formal enforcement action
for a contravention of the Building Regulations?
If the Council is to serve notice under Section 36 of the Building Act
then it must do so within 12 months of the offence occurring.
Proceedings for a fine must be taken within 6 months and there is
also provision for a continuing daily financial penalty. However, in
respect of serious public safety infringements there is provision to
enable anyone, including the Local Authority, to seek an injunction
from the Courts which is not subject to the same time constraints.
Please see the Enforcement Policy.

Q21 Can I get previously unauthorised building work regularised?
It is possible for unauthorised building work, which was commenced
on or after November 1985 to be regularised. You will need to make
an application for a Regularisation Certificate. Please see our page on
Building work carried out without approval. Return to top
