Requirement S5 and regulation 44H: Buildings other than residential buildings
undergoing major renovation work

This section deals with requirement S5 from Part S of Schedule 1 and regulation 44H of the Building Regulations 2010.

Requirement

Buildings undergoing major renovation which are not residential buildings or mixed-use buildings

S5. Where a building undergoing major renovation, which is not a residential building or a mixed-use building, will have more than 10 parking spaces after the major renovation is completed:

(a) one of those parking spaces must have access to one electric vehicle charge point; and

(b) cable routes for electric vehicle charge points must be installed in a minimum of one fifth of the total number of remaining parking spaces.

Regulation

Application of paragraph S5 of Schedule 1 (buildings undergoing major renovation which are not residential buildings or mixed-use buildings)

44H. (1) The requirements of paragraph S5 of Schedule 1 apply to a building undergoing major renovation, which is not a residential building or a mixed-use building, as follows.

(2) The requirements of paragraph S5 of Schedule 1 apply to such a building if:

(a) the major renovation involves building work being done which includes work being done to any of the following:

(i) a car park that is located within the site boundary of the building, where the nature of the work is
such that it would be reasonable to expect the requirements of paragraph S5 of Schedule 1 to be
fulfilled;

(ii) the electrical infrastructure of a car park, where the car park is located within the site boundary of
the building;

(iii) the electrical infrastructure of the building, where a car park is located inside the building;

(b) upon completion of that major renovation, the building will have more than 10 parking spaces situated within the site boundary of the building;

(c) the cost of installing the required electric vehicle charge point and cable routes for electric vehicle
charge points does not exceed 7% of the total cost of the major renovation.

Regulation continued

(3) If the cost of installing the required electric vehicle charge point and cable routes for electric vehicle charge points exceeds 7% of the total cost of the major renovation:

(a) such a building is exempt from the requirement to install the electric vehicle charge point; and

(b) cable routes for electric vehicle charge points must be installed in a minimum of one fifth of the total number of parking spaces, except where the cost of that installation exceeds 7% of the total cost of the major renovation.

(4) If such a building has, or will have, within its site boundary, more than 10 parking spaces:

(a) if there are or will be any parking spaces situated in a position other than in a covered car park:

(i) the requirements of paragraph S5 of Schedule 1 must first be applied in relation to those parking
spaces; then

(ii) if the number of parking spaces which are situated in a position other than in a covered car park
is insufficient to completely fulfil the requirements of paragraph S5 of Schedule 1, cable routes for
electric vehicle charge points must be installed in the number of parking spaces in the covered car
park in order to ensure compliance with the requirements of paragraph S5(b) of Schedule 1;

(b) if all the parking spaces are situated in a covered car park, cable routes for electric vehicle charge
points must be installed in a minimum of one fifth of the total number of those parking spaces.

NOTE: Where the building control body is an approved inspector, see regulation 8 of the Building (Approved Inspectors etc.) Regulations 2010 (as amended).

Intention

In the Secretary of State’s view, requirement S5 and regulation 44H will be met if building work
complies with the following.

a. For major renovations to buildings other than dwellings with more than 10 parking spaces, both of the following are provided.

i. One electric vehicle charge point, as described in paragraphs 4.1 to 4.6.

ii. Cable routes for at least one in every five remaining parking spaces, as described in paragraphs 4.1 to 4.6.

Section 4: Major renovations of buildings which are not residential or mixed-use buildings

4.1 For a building other than a residential or mixed-use building where all of the following apply, cable
routes and electric vehicle charge points must be provided.

a. Major renovation work is being done.

b. After work is complete, more than 10 parking spaces within the site boundary will be available for the use of building users.

c. The major renovation work includes any of the following within the site boundary.

i. Substantial work to the car park, such as resurfacing or installing electrical infrastructure.

ii. Where the car park is outside the building but within the site boundary of the building, the
electrical infrastructure of the car park.

iii. Where the car park is inside the building, the electrical infrastructure of the building.

4.2 Where the criteria in paragraph 4.1 are met, the following apply.

a. One electric vehicle charge point must be installed.

b. A minimum of one in five of the remaining parking spaces must have access to cable routes.

NOTE: A minimum of one in every five means that, for example, if there are 11 parking spaces, two parking spaces must have access to cable routes in addition to the one parking space with an electric vehicle charge point.

Application of major renovation requirements for buildings other than residential or mixed-use buildings

4.3 For a building other than a residential building or mixed-use building undergoing a major renovation, the requirement to install electric vehicle charge points and cable routes applies as follows.

a. Where the cost of installing at least one electric vehicle charge point and cable routes for at least one in every five remaining parking spaces is not more than 7% of the total cost of the major renovation, the requirements apply, as described in paragraphs 4.1 and 4.2.

b. Where the cost of installing electric vehicle charge points and cable routes is more than 7% of the total cost of the major renovation, requirement S4 and regulation 44H can be met by installing only cable routes in a minimum of one in five parking spaces.

c. Where the cost of installing only cable routes is more than 7% of the total cost of the major renovation, there is no requirement to install either electric vehicle charge points or cable routes.

4.4 The cost set out in paragraph 4.3 is the cost of materials and labour, excluding VAT. The cost is the cost of the electric vehicle charge points and cable routes themselves compared to the total cost of the major renovation including the electric vehicle charge points and cable routes. The cost should exclude land or property acquisition, statutory fees, insurance, taxation, financing, maintenance or operational costs. The methodology for determining costs should be consistent between all elements of the calculation to allow a fair comparison between the cost of the major renovation and the cost of electric vehicle charge point infrastructure.

4.5 Where one or more parking spaces are within a covered car park, the requirement to install electric vehicle charge points should be met by installing charge points in parking spaces that are not
within a covered car park. Cable routes must still be provided for a minimum of one in five parking
spaces. The requirement to install cable routes only applies to parking spaces within a covered car park if there are insufficient parking spaces outside the covered car park to meet paragraph 4.2b.

4.6 Where all parking spaces are within a covered car park, the requirement to install an electric vehicle charge point does not apply. Cable routes must still be provided for a minimum of one in five parking spaces.
