“ Materials 4.1 All materials used to cover roofs , excluding windows of glass in residential buildings with roof pitches of not less than 15°, shall be capable of safely withstanding the concentrated imposed loads upon roofs specified in BS EN 1991-1- 1:2002 with its UK National Annex. Transparent or translucent covering materials for roofs not accessible except for normal maintenance and repair are excluded from the requirement to carry the concentrated imposed load upon roofs if they are non-fragile or are otherwise suitably protected against collapse. Re-covering of roofs 4.2 The re-covering of roofs is commonly undertaken to extend the useful life of buildings. Roof structures may be required to carry underdrawing or insulation provided at a time later than their initial construction. This section provides guidance on determining whether such work to a roof constitutes a material alteration under the Building Regulations. 4.3 Where the work involves a significant change in the applied loading the structural integrity of the roof structure and the supporting structure should be checked to ensure that upon completion of the work the building is not less compliant with Requirement A1 than the original building. 4.4 A significant change in roof loading is when the loading upon the roof is increased by more than 15%. Consideration might also be given to whether the roof covering being replaced is the original as-built covering. 4.5 Where such checking of the existing roof structure indicates that the construction is unable to sustain any proposed increase in loading (e.g. due to overstressed members or unacceptable deflection leading to ponding), appropriate strengthening work or replacement of roofing members should be undertaken. This is classified as a material alteration. 4.6 In carrying out the checks mentioned in paragraph 4.3 an increase of stress in a structural member arising from increased loading does not necessarily indicate that the roof structure is less compliant than the original roof provided an adequate factor of safety is maintained. 4.7 Where work will significantly decrease the roof dead loading , the roof structure and its anchorage to the supporting structure should be checked to ensure that an adequate factor of safety is maintained against uplift of the roof under imposed wind loading.”
“6.1 This section gives guidance for three situations: a. roofs exposed to precipitation from the outside (see paragraphs 6.3 to 6.9); b. the risk of interstitial condensation in roofs (see paragraphs 6.10 to 6.13); c. the risk of condensation or mould growth on the internal surface of roofs (see paragraph 6.14). 6.2 Roofs should: a. resist the penetration of precipitation to the inside of the building; and b. not be damaged by precipitation and not carry precipitation to any part of the building which would be damaged by it; c. be designed and constructed so that their structural and thermal performance are not adversely affected by interstitial condensation. ROOFS (RESISTANCE TO MOISTURE FROM THE OUTSIDE) 6.3 Roofing can be designed to protect a building from precipitation either by holding the precipitation at the face of the roof or by stopping it from penetrating beyond the back of the roofing system . 6.4 Any roof will meet the requirement if: a. it is jointless or has sealed joints, and is impervious to moisture (so that moisture will not enter the roofing system ); or b. it has overlapping dry joints, is impervious or weather resisting, and is backed by a material which will direct precipitation which enters the roof towards the outer face (as with roofing felt). 6.5 Some materials can deteriorate rapidly without special care and they should only be used as the weather-resisting part of a roof if certain conditions are met The weather-resisting part of a roofing system does not include paint nor does it include any coating, surfacing or rendering which will not itself provide all the weather resistance. 6.6 Roofing systems may be: a. impervious including metal, plastic and bituminous products; or b. weather resisting including natural stone or slate, cement based products, fired clay and wood; or c. moisture resisting including bituminous and plastic products lapped at the joints, if used as a sheet material, and permeable to water vapour unless there is a ventilated space directly behind the material; or d. jointless materials and sealed joints, which would allow for structural and thermal movement. … 6.8 Each sheet, tile and section of roof should be fixed in an appropriate manner. Guidance as to appropriate fixing methods is given in BS 8000-6:1990.”

“Where the supply is of a roof, either a complete replacement or the addition of tiling to the existing roof, the whole supply must be charged VAT at the standard rate.”
“240. … In CPP the Court held ‘27. It must be borne in mind that the question of the extent of a transaction is of particular importance, for VAT purposes, both for identifying the place where the services are provided and for applying the rate of tax or, as in the present case, the exemption provisions in the Sixth Directive. In addition, having regard to the diversity of commercial operations, it is not possible to give exhaustive guidance on how to approach the problem correctly in all cases. 28. However, as the Court held inCase C-231/94 Faaborg-Gelting Linien v Finanzamt Flensburg[1996] ECR I-2395 , paragraphs 12 to 14, concerning the classification of restaurant transactions, where the transaction in question comprises a bundle of features and acts, regard must first be had to all the circumstances in which that transaction takes place. 29. In this respect, taking into account, first, that it follows from Article 2(1) of the Sixth Directive that every supply of a service must normally be regarded as distinct and independent and, second, that a supply which comprises a single service from an economic point of view should not be artificially split, so as not to distort the functioning of the VAT system, the essential features of the transaction must be ascertained in order to determine whether the taxable person is supplying the customer, being a typical consumer, with several distinct principal services or with a single service. 30. There is a single supply in particular in cases where one or more elements are to be regarded as constituting the principal service, whilst one or more elements are to be regarded, by contrast, as ancillary services which share the tax treatment of the principal service. A service must be regarded as ancillary to a principal service if it does not constitute for customers an aim in itself, but a means of better enjoying the principal service supplied (Joined Cases C-308/96 and C-94/97 Commissioners of Customs and Excise v Madgett and Baldwin[1998] ECR I-6229 , paragraph 24). ..... 32. The answer to the first two questions must therefore be that it is for the national court to determine, in the light of the above criteria, whether transactions such as those performed by CPP are to be regarded for VAT purposes as comprising two independent supplies, namely an exempt insurance supply and a taxable card registration service, or whether one of those two supplies is the principal supply to which the other is ancillary, so that it receives the same tax treatment as the principal supply.’ 241. The test for determining whether one element of a supply is ancillary to another is thus whether it “constitutes for customers” an aim in itself or a means of better enjoying the principal service” (paragraph 30); the customer to be considered is “a typical consumer” of the supply in question (paragraph 29).’ FDR 242. My attention was also drawn to Customs and Excise Commrs. v FDR Ltd[2000] STC 672 . In that case FDR performed a complicated series of inter-connected functions for banks in relation to credit cards which, again, would if viewed in isolation be variously taxable and exempt. The particular feature of Laws LJ’s judgment in that case (with which the other members of the Court concurred) was that it articulated the distinction between CPP -type cases in which there is a principal element of the supply to which other elements are ancillary and those in which there is “a congeries of supplies” which without being in a relationship of principal and ancillary “are integral to each other or ‘indissociable’”
‘53 ... I am sure with very great respect that Lord Millett did not intend, in the first four sentences of the passage I have just cited [in C & E Commrs. v Wellington Private Hospital Ltd[1997] STC 445 at 462], to indicate that in every case where multiple supplies properly fall to be treated as a single supply for fiscal purposes there is always a single or unitary dominant supply to which all the other supplies in question are then regarded as ancillary. That, certainly, is one case; but there may be others where the single supply that is arrived at for VAT purposes consists, not in one supply to which others are ancillary, but in a bundle of supplies none of which predominates over the others; the single supply may, as it were, be an apex or a table-top. There is thus a difference between what is “ancillary” and what is “integral”: several supplies may be “integral” to one another, with none predominating - the table-top - and this I think is the situation contemplated by the phrase “physically and economically dissociable”, quoted by Lord Millett and appearing in some of the Court of Justice jurisprudence, and by Lord Nolan’s expression “the true and substantial nature of the consideration given for the payment”.... 54 While I hope these observations are helpful I think there is some danger of over-elaboration and needless complexity in this field. We are not here concerned with deep legal principle, but with the articulation of a fair and reasonable approach to those cases where there is a question how should the consideration given by a supplier for his reward be categorised for the purposes of VAT, when there are multiple acts of supply involved. The simpler it is the better, so long as it is kept consistent with the doing of justice. With respect I apprehend (but I by no means propose to lay down any rule) that where this sort of issue arises, the first question to be asked may be couched as Lord Nolan put it: what is “the true and substantial nature of the consideration given for the payment”. That will identify the apex or the table-top. The second question will be whether there are other supplies which are ancillary to the core. 55 But there is, I think, one further complication. Where the core supply is on the table-top model - a congeries of supplies which are integral to each other or “indissociable” - it may not be self-evident from the description of the core supply at which the court or tribunal arrives what its tax treatment should be. In that case, it will be necessary to look again at the elements which comprise the core, and arrive at a decision on the facts whether, numerically if nothing else, the taxable or exempt elements predominate. Necessarily no such difficulty arises where the core supply is on the apex model.’
“Article 6(1) of the Sixth Directive must be interpreted as meaning that such a single supply is to be classified as a ‘supply of services’ where it is apparent that the customisation [of software also supplied] in question [in that case] is neither minor nor ancillary but, on the contrary, predominates; such is the case in particular where in the light of factors such as its extent, cost or duration the customisation is of decisive importance in enabling the purchaser to use the customised software.”
“ The Products 4. The principal Product, the Insupolycarbonate Roofing Panel, consists of polycarbonate materials comprising four or more cells. Polycarbonate does not have the structural rigidity for use on its own as a panel; the Product is therefore manufactured as a cellular structure and designed to fit into an aluminium frame. The frame holds cells with thicknesses of either 25mm or 35mm. The thicker the panel the higher is the insulation performance. The insulation panels are designed to admit daylight into the conservatory. A “thermal break” consisting of opaque insulating material may be attached to the aluminium framework structure to reduce heat loss due to conduction. … The services provided by Pinevale 12. Mr Anderson said that the conservatories with which Pinevale dealt would have been extensions of existing houses that have been in place and used for several years. The procedure starts with a meeting at which Pinevale’s representative and the client discuss the available methods of insulating both to keep heat in during the winter and to maintain cooler temperatures during the summer. The solution may be the replacement of faulty components such as glazing bars, crests or valleys, failed panels or sealed units. The replaced panels may be Insu high performance polycarbonate light weight insulation or glass-sealed units. Where the conservatory requires a complete new roof structure and the existing eaves beam is sufficiently strong, then the entire roof can be replaced or the style or shape of the roof can be changed. The solution may simply be the insertion of radiation reflector strips into the existing cellular structure. … Is the relevant Product “insulation for… roofs?” … 25. HMRC are, in my view, adopting too constrained a meaning of “insulation for” when they seek to exclude the situation where the whole roof structure is replaced or where individual panels are. It is in my view, significant that HMRC have identified no form of energy-saving material that is ordinarily attached to an existing but energy-inefficient roof. I accept that a second layer of glass (when installed to create a double glazed roof) may function as energy saving, but the glass itself is not energy saving material. 26. The evidence summarised above shows that Pinevale’s market for the Product is customers who want to have the Product installed in the construction or repair of roofing insulated with energy-saving materials. The Product is designed for no other purpose. Those points further indicate that the Product is “insulation for roofs”
“4. The roof panels in issue are used to form the roof of a conservatory, either (as Pinevale considered desirable for achieving maximum effect) replacing or constituting the entire roof, or replacing parts of an existing roof. Their purpose is to achieve much higher levels of insulation than would be the case with a conventional conservatory roof, including a double-glazed roof. … 8. HMRC’s case before the FtT, and on this appeal, is that the panels are not “insulation for roofs” but are the roof itself. So, if an entire existing roof is replaced, the panels constitute the new roof, not just insulation for a roof. Likewise, the replacement of individual panels with Pinevale’s panels was the supply of new roof panels, not the supply of insulation for a roof. … 17. There is a distinction between Note 1(a), which specifies insulation “for walls, floor, ceilings, roofs or lofts or for water tanks, pipes or other plumbing fittings” and paragraphs (c) to (j) which specify particular products such as central heating system controls or solar panels. A material which is insulation for a roof is not the same thing as the roof itself. It presupposes that there is a roof to which the insulating material is applied. If the intention had been to apply the reduced rate of VAT to energy-efficient roofs or walls, this could have been specified, just as more generally building materials are specified in schedule 8. The same point can be made in respect of water tanks. It is not energy-efficient water tanks, such as those which incorporate insulation as part of their construction, which attract the reduced rate of VAT, but insulation for water tanks. Again it presupposes that there is a water tank to which an insulating material is attached or applied. 18. In [25] of its Decision, the Tribunal considered it to be significant that HMRC had not identified any form of energy-saving material that is ordinarily attached to an existing but energy-inefficient roof. While HMRC’s representative at the hearing before the F-tT did not have the information to deal with this point, it is in fact clear that there are many such products available generally in the market. 19. The error, in my judgment, made by the Tribunal was to construe “insulation for roofs” as extending to the roof itself when it has energy-saving properties, rather than being confined to insulating materials attached or applied to a roof.”
“11. The F-tT identified the relevant legal questions at[18] as being: “The question of law is whether Pinevale’s supplies are of, or relate to, energy- saving materials that are “insulation for....roofs”
