Who notifies building control about a rooflight?
In law the duty sits with the person having the work carried out, which means the homeowner, and in practice the notification is made by whoever is doing the building work on their behalf. Those two statements are both true and they are the source of most of the confusion. The regulations make the building owner responsible for the work complying; the paperwork is normally submitted by the contractor as part of the job, in the owner’s name, and the certificate at the end comes back to the owner. This page is about the mechanism: what is notified, at what point, by whom, what the inspector looks at, and what document exists at the end. Whether the notification needs making at all is answered on the page about building regulations approval for a rooflight, and how Severn organises it on a live job is on handling the building control notification.
Two bodies can receive it, and they are not the same route
Building control in England is delivered by two kinds of body. The first is the local authority, which has a statutory building control department covering its own district. The second is a registered building control approver working in the private sector, historically called an approved inspector, which can take on work anywhere and is common on larger projects and on developer led sites.
For a single rooflight in an existing house the local authority route is the ordinary one, and it is usually the cheaper and simpler of the two. Where a private approver is used, the mechanism changes slightly: an initial notice is served jointly by the approver and the client on the local authority, and the council’s own control function steps aside for that project. Either way the same technical standards apply and the same completion document results.
Which authority covers a Gloucestershire address
The county is split between district and borough councils, and the address decides which one. Gloucester City Council covers the city and its suburbs from Kingsholm and Barnwood out to Quedgeley and Hempsted. Cheltenham Borough Council takes Cheltenham, Leckhampton, Prestbury and Charlton Kings. Tewkesbury Borough Council covers Churchdown, Bishops Cleeve, Ashchurch and the vale to the north.
Stroud District Council takes the valleys, Stonehouse, Dursley and Berkeley. Cotswold District Council covers Cirencester, Northleach, Bourton, Stow and the wolds villages. Forest of Dean District Council covers Coleford, Cinderford, Lydney, Newent and Mitcheldean. Several of these operate as shared or partnered teams, which changes the branding on the portal rather than the substance of the process, and jobs near the county edge at Chepstow, Ross on Wye or Ledbury fall to Monmouthshire, Herefordshire or Malvern Hills instead.
What is actually notified
The submission is a description of the building work, not a description of the product. A rooflight notification names the property, identifies the owner, describes the work as forming a new opening in a pitched or flat roof for a glazed unit, states the intended start date, and encloses whatever technical information the route requires.
On a full plans application that means drawings: a plan showing the position of the opening against the rafters or joists, a section through the roof showing the build up, the frame position, the insulation line and the reveal, and a specification for the unit including its U-value and glazing make up. On a building notice it can be as little as a clear written description and a location plan, with the detail judged on site. Either way the fee is calculated from the value or the category of the work rather than the size of the glass.
When it goes in, and why that is before the covering comes off
A building notice requires at least two clear days’ notice before work starts. A full plans application needs longer, because it is assessed and determined, and five weeks is the statutory period although straightforward domestic work is often turned round faster than that.
That is the practical scheduling point. Glass lead times and inspector lead times run in parallel, and the one that governs the start date is whichever finishes later. Booking a survey early enough that both can run without pressure is the whole argument on the page about how far in advance to book.
Structural calculations, and when they travel with it
An opening inside one rafter bay with doubled trimmers is a standard detail that most inspectors accept without a calculation. Once the opening crosses two or three bays, or once a trussed rafter has to be carried on a beam, the flanking members are taking loads they were not sized for, and an engineer’s calculation is produced and submitted with the application.
That calculation is worth having in the file even when the inspector does not insist on it, because it is the document that answers the question a purchaser’s surveyor asks a decade later about the timber visible in the loft. Where it applies, it is prepared before the application rather than after the covering is stripped, since the trimmer size decides the opening size and the opening size decides the unit.
The stages an inspector wants to see
Inspection is by stage, not by appointment count, and on a rooflight there are normally two or three that matter.
- Opening formed. Trimmers in, the cut ends supported, the structure visible before anything covers it.
- Before the reveal is closed. Insulation continuous around the frame, the vapour control layer taped to it, the ventilation gap above the insulation still clear.
- Completion. The finished unit, the weathering, the glazing specification and any electrical certificate for a powered opener.
The middle one is the one people lose. Once the plasterboard is on, the only evidence that the insulation runs tight to the frame is a photograph, so the sequence is planned so the inspector or the photographs arrive at the right moment. Site photographs at each stage go into the completion pack either way.
Fees, and where they appear on a quotation
Councils publish their own charges, they differ between the Gloucestershire authorities, and they are normally split between a plan charge and an inspection charge, or presented as a single building notice charge. The fee is set by the authority rather than by the contractor.
On a written quotation it should appear as its own line rather than being folded into labour, so that it is clear what is unit, what is labour, what is scaffold and what is statutory. That is one of the things the page on reading a rooflight quotation looks at, and the general pricing process sits on the costs page.
The completion certificate, and whose name is on it
When the final inspection is satisfied, the authority issues a completion certificate. It names the property and the owner, references the application number, and states that the work described has been completed and inspected. A private approver issues a final certificate instead, which serves the same purpose and is copied to the council.
It is issued to the building owner, not to the contractor, and it belongs with the deeds. It is not a guarantee of workmanship and it is not a warranty on the glass; those are separate documents with separate terms. What it is, is the evidence that the work was notified and signed off, and it is the single piece of paper a buyer’s solicitor asks for when a survey notes a rooflight newer than the roof around it.
Work already done, and the way back into the system
Where a rooflight went in years ago and nobody notified anything, two routes exist. A regularisation application asks the authority to inspect and certify work retrospectively, which on a roof means opening up part of the reveal so the structure and the insulation can be seen. It produces a regularisation certificate, which is not identical to a completion certificate but satisfies most conveyancing enquiries.
The alternative is an indemnity policy, bought by the seller, which insures against enforcement rather than proving compliance. Solicitors accept it routinely and surveyors are less impressed by it. Where an existing unit is being replaced anyway, the sensible move is to notify the replacement properly and let the new certificate cover the current work, which is discussed on the page about permission to replace a rooflight. The whole process, survey to certificate, is set out on the skylight and rooflight installation page.
