Sun tunnel installation in Berkhamsted

Our guide price for sun tunnel installation starts from £595, and the real figure for your roof in Berkhamsted depends on a handful of things: the size and type of sun tunnel, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of Hertfordshire.

Where our fitters travel

Berkhamsted and the districts around it, HP4, HP1 and HP3, all sit inside our working area. So does the ground between Berkhamsted and Chesham (4 miles), and on towards Hemel Hempstead (5 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Fit-only or supply and fit

If you have bought a sun tunnel yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the flashing kit and the roof pitch range. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

On the day, we cover

  • Dome fixed and sealed on top of the flashing
  • Ceiling opening cut neatly and the diffuser fitted
  • Route through the loft checked for joists, cables and pipes
  • Length and bends in the tube — We plan the shortest, straightest route we can between the roof and the ceiling.
  • Tube size — We match the tube size to the room and the roof.

How a fitting day runs

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a sun tunnel runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Regulations for Berkhamsted properties

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

Before you get in touch

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 HP4 and we will come back with a quote or a survey date.

Common questions in Berkhamsted

Do you cover Berkhamsted?

Yes. Fitters travel to addresses in Berkhamsted and the surrounding districts, including HP4. 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.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.

What if my roof opening is the wrong size for the sun tunnel?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
