Rooflight upstands & kerbs in Basingstoke

An upstand is the timber kerb a flat-roof rooflight sits on, and most fitting problems start there. Each maker sets the kerb size, the minimum height above the finished roof and whether the kerb should be level or built to a fall. We build upstands in Basingstoke to those figures for the rooflight you have chosen, insulate the faces that need it and dress the roof membrane up and over so the kerb is weathertight. Every job is quoted in writing first.

Areas around Basingstoke we cover

Looking at a property near Basingstoke but not quite in it? We work across RG21, RG24 and RG22 and outwards to Tadley, Alton and Fleet. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Basingstoke.

What we do on the day

  • Kerb sized from the maker's drawing, internal and external dimensions both checked
  • Height set above the finished roof to the maker's stated minimum
  • Treated timber frame fixed down to the deck and joists
  • Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
  • Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.

Fitting your rooflight upstand, step by step

On the day, the fitters check the opening and the roof deck around it, then cut and fix treated timber to the maker's kerb size, square and level, with any fall the rooflight needs built in. Insulation goes on the faces that need it, and the roof membrane is turned up and dressed so the kerb is weathertight before anyone leaves. Most upstand jobs take half a day to a day.

Planning and building rules in England

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Help us quote accurately

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around RG21 and we will come back with a quote or a survey date.

Common questions in Basingstoke

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

Do I need planning permission for a rooflight in Basingstoke?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Do you cover Basingstoke?

Yes. Fitters travel to addresses in Basingstoke and the surrounding districts, including RG21. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

Tell us your postcode, RG21 or close by, and what you want fitted. We will reply with the next steps and a quote.
