Coverage in and around Thamesmead
Covering Thamesmead means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in SE28, SE2 and DA18, and are happy to quote further out in Abbey Wood and Plumstead. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
Fit-only or supply and fit
Your unit or ours, the fitting standard is the same. For supply and fit we choose a roof access hatch to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.
On the day, we cover
- Locks, catches or handles checked from inside and out
- Opening and upstand sized for a clear climb-through, not just daylight
- Opening and closing tested and the controls explained
- Clear opening size — We check the hatch's clear opening rather than its outer size.
- Safety at the roof edge — We ask how often people will use the roof and for what.
Fitting your roof access hatch, step by step
Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a roof access hatch: one day, weather permitting.
Do you need permission in Thamesmead?
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.
Getting a price from photos
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 SE28. That is enough for a first price.
Common questions in Thamesmead
What upstand height and roof pitch does roof access hatch fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Do you cover Thamesmead?
Yes. Fitters travel to addresses in Thamesmead and the surrounding districts, including SE28. 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.
How long does fitting take?
Fitting a roof access hatch into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
