Areas around Ruislip we cover
Jobs across HA4, UB10 and HA5 are part of our normal cover for Ruislip. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Pinner and Northolt are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Your sliding rooflights or ours
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a sliding rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
What the job includes
- Upstand checked for strength, square and level along its full length
- Full open and close cycle checked before handover
- Controls, sensors and any safety stop set up and tested
- Guarding on the terrace — We look at how the roof terrace will be guarded before the rooflight is fitted.
- What the glass slides over — We check the area the glass will cover when open before deciding where the unit goes.
What happens on the day
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a sliding rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days.
Regulations for Ruislip properties
Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.
Help us quote accurately
Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around HA4. That is enough for a first price.
Common questions in Ruislip
Can you fit the sliding rooflight I bought online?
Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
Do I need planning permission for a rooflight in Ruislip?
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 Ruislip?
Yes. Fitters travel to addresses in Ruislip and the surrounding districts, including HA4. 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.
