Tibshelf colliery-era homes with skylights and rooflights

17.4 road miles north of Derby, where two railways once met the coalfield.

Tibshelf grew with its pits, and its homes have been altered since by generations of owners. Whichever table or room is dim, the survey begins there.

Fitting daylight to Tibshelf houses

For Tibshelf the usual answers are VELUX windows and other roof windows in lofts, a flat roof rooflight or taller lantern over an extended dining area, sun tunnels for hallways, and where old glass has clouded, replacement of misted units.

Tables are where a household gathers, for meals, homework, jigsaws and bills. They also tend to stand well inside the house, far from any window. A table in a dining room with a rear extension may sit under a flat roof, and a table in the old back room may sit under a loft. The unit is chosen for what is above the table, and the written quote says precisely what that is.

The full guide

From the Tibshelf table up to the sky

People define a house by its table. It is where the day's news is swapped and the post gets opened. If the table is dim, the whole house feels dim, whatever the front windows are doing. This is how we light that one place from the roof, and what that involves in a village like this.

The dining table, hardest spot in the house to light

A table seldom stands against a window. Chairs need to go all round it, so it takes the room's centre, which is the point farthest from the glass. The window light that does arrive comes at a low angle, and half the people at the table sit with their backs to it, reading their own shadows. By late afternoon, in most months, the lamp goes on.

A roof window above the table fixes the geometry. The light falls straight down, so every seat gets a share, and no one is stuck facing a glare or sitting in a shadow. The aim is not a spotlight. It is an even wash of daylight across the tabletop and the faces around it, which is why the glass is centred on the table, or just beyond its centre line, rather than set against a wall.

The table sets the size. Seating for four is served by a single medium unit. A table for eight, or one that doubles as homework desk and hobby bench, may want a larger unit or two side by side. We measure the table, the number of chairs and the clearance around them, and draw the glass over that footprint.

A dining table is also a place where heat and glare matter. Sunlight falling straight on a polished table is dazzling at the wrong time of day. A blind that runs close to the glass and a coating that tames the sun keep the table comfortable. A table looked at in January needs the same thinking as one used in July.

Light a table from the centre of the room and every chair shares it.

Reading the roof above a Tibshelf back room

Tibshelf is a village with a long working history. It was recorded in Domesday in 1066, and in the nineteenth century coal was discovered, which pushed mining past agriculture as the main industry and brought a local railway system. A place that grows quickly in one era tends to have houses of similar age and construction, and then a ring of later additions. We do not claim to know each street, but we can describe what a loft survey usually looks for in that kind of housing.

In an older house, the roof is often a cut roof with purlins and common rafters. The timbers carry the roof covering and resist the weight of tiles or slate. A roof window set between the rafters is the cleanest fit, as it needs the least cutting, and a window sized to the rafter gap saves trimming. Where a window needs to be wider than the gap, a pair of rafters is cut, and a proper header carries the load around the opening.

In newer houses the roof is often trussed. The webs between rafters limit the position of the opening, and sometimes the window has to move a little to avoid them. A trussed roof also means the loft is less usable as a room, so a roof window there tends to light a landing, a stair or a first-floor room through a short light well.

Extensions have flat roofs more often than not. A flat roof asks for a joisted opening, an upstand built up from insulated timber, and the roof covering dressed over it. Done well, it is as watertight as any pitched slope. Done badly, it leaks within a winter, which is why the build-up is described in the quote.

Bolsover's rules, and the Building Regulations behind them

Bolsover District Council is the planning authority for Tibshelf, with its guidance at bolsover.gov.uk. On a house, adding a rooflight is often possible through permitted development, with strings attached that are explained in the planning guide, together with the official wording. Householder rights exclude flats and maisonettes, and a listed home requires consent for nearly any alteration. No conservation area is assumed for Tibshelf in this page. Where an older property raises a doubt, Bolsover itself can answer, and the question goes to it before anything is drawn.

Separate from planning, the Building Regulations govern the structure and the heat loss. A hole cut through roof timbers counts as building work, and its sign-off comes from a registered building control approver or the council. Swapping one unit for its equivalent is treated differently, since Part L sets a heat-loss ceiling on the incoming glass, 1.4 W/m²K goes with roof windows, and a more forgiving 2.2 with rooflights. Where a notification is due, it is ours to send.

A new loft room brings in the escape rules. Approved Document B lets a sloping window act as the exit only from a floor close to the ground, with 4.5 m as the limit, and the opening must be a free 0.33 m² and never narrower than 450 mm anywhere. A loft over two full storeys is left to a protected stair. All of this is checked at the survey so the drawing starts out right.

Making the whole ground floor feel lighter

A table window helps the table first, and the rest of the room second. In an open-plan layout the light spreads into the kitchen and sitting area, especially when the ceiling and walls are pale. A white or light-grey splay around the opening throws the daylight further than a dark one.

Where the rooms stay separate, a door left open between them lets a bright dining room share its light with a hall. If the hall is still dim, a sun tunnel can borrow daylight from the roof through a dome and a mirrored tube, finishing in a ceiling diffuser. It offers no view, though it does lift the gloom.

Artificial light still has its place in the evening, and a rooflight does not replace it. What it does is shift the hour at which you reach for the switch, and in winter that hour matters. A table that is bright until four is a different table from one that needs a lamp at two.

A rooflight that has misted or leaked already occupies the right opening. Fresh glazing in the same place usually makes a clear difference, above all when the old unit was single glazed. Should a unit be beyond repair, the survey says so in plain words and the quote covers its replacement.

A coalfield village with a railway past

Tibshelf sits in the Bolsover district of Derbyshire, between Clay Cross, Shirebrook, Mansfield and Chesterfield. It had a population of 4,348 at the 2021 Census, and the settlement was recorded in Domesday in 1066. In the nineteenth century coal was discovered and mining overtook agriculture as the main industry. A local railway system grew with it.

The railways left their mark on the village's name for itself. Two stations once served Tibshelf. One, Tibshelf & Newton, stood on a Midland Railway branch line from Westhouses & Blackwell on the Erewash Valley Line, and it closed to passengers in 1930, though freight and coal trains continued for years. The route is now a footpath. The other, Tibshelf Town, opened in 1893 on the Manchester, Sheffield & Lincolnshire Railway, later part of the Great Central Railway, and its name reflected the village's hope of official town status, which it never received. A third station, Doe Hill, on the Erewash Valley Line, served Stonebroom and Morton and closed in 1960.

A village that grew with its pits is likely to have its homes from different periods side by side: earlier terraces and cottages close to the old centre, interwar and post-war housing further out, and newer estates on the edges. We would not tie a type to a named street without seeing it, and we do not need to. At the survey we see how the house is built and what is above the spot, and that settles the rooflight.

Few Tibshelf homes will be as first built. Picture a back kitchen pushed out into the garden, a loft boarded for storage or turned into a bedroom, a through-room knocked together from two smaller ones. Each of these changes can leave a dim spot, and each is a candidate for a roof window, a lantern or a sun tunnel.

Newton lies just to the south, and the picture there is much the same. Add the room and the spot to the survey form, and the visit is fitted around your day.

Questions from Tibshelf homes

How big a roof window do I need over a family dining table?

The window is sized from the table, not the room. A table for four is usually served by one medium unit, while a larger table may want a bigger window or a pair. We measure the table and chairs at the survey and draw the glass over that footprint.

Can a roof lantern go on the flat roof of a Tibshelf extension?

Usually, provided the roof can carry it and the ceiling is tall enough. The lantern stands on an insulated upstand, and the roof is dressed up to it. If height is limited, a flat rooflight does a similar job lower down.

Does the planning guide cover Tibshelf as well as Derby?

Permitted development rules apply across England, so the guide is relevant here. The local planning authority is Bolsover District Council, and we ask it about any special controls at your address before the survey.

Moisture has appeared inside our rooflight glass. Can the unit be replaced?

Yes. A misted pane is a sign of a broken seal, and a unit in that state has had its day. The newcomer takes the same opening with current glazing, and Part L sets the heat-loss limit it must meet.

What does a Tibshelf fitting day involve, and how long is it?

For one straightforward unit the time up on the roof is normally a day or two, and lining and decoration follow indoors. The written quote lists the stages, and the price on it is the price you pay.
