Looking up in Shefford, with a skylight or rooflight overhead
Shefford grew where the road from Bedford to Hitchin crossed two rivers, and its old streets and newer extensions each ask a different question of the roof. Both answers start by looking up.
Between the Flit and the Hit
The name Shefford means sheep ford, and the town is a product of its water. It grew up between a pair of fords where the main road from Bedford to Hitchin crosses the River Flit and the River Hit, and both rivers still run through it. A market was already being held here by 1225, and the formal charter followed in 1229. A canal arrived in 1823 when the Ivel Navigation was extended to the town, and a railway station opened in 1857, though passengers stopped using it in 1961.
Those centuries left a town of two parts: a historic core that was built up gradually, and an edge of later houses where families are now adding space.

Town-centre houses along the old market streets
-
Family houses with a rear extension
A town with a market charter from the thirteenth century has a long-settled centre, and the buildings along it have been altered over the years. Roofs vary in pitch and covering, upstairs rooms are tucked under the slope, and some of the back rooms look across a yard at a neighbouring wall. This kind of roof is well served by a slim conservation rooflight, which sits close to the covering and keeps the line of the tiles intact. Shefford has a conservation area, so it is sensible to ask the council before ordering anything.
Away from the centre the housing is later, and the way homes grow is different. A single-storey extension is added to the back, a bathroom is squeezed into a loft or a first-floor corner, and a boundary fence or garden wall sits not far from the new glass. Over the extension, a lantern or a flat rooflight in the roof puts daylight in the middle of the room, while a roof window or sun tunnel brings it into the bathroom.
What the sky can do for a Shefford house
An extension with a wall at the window
More floor space, but not much more light.
Sideways
An extension solves one problem and starts another. The family gets a kitchen that fits a table, but the new room sits closer to the boundary than the old one did. The glazed doors at the back face a fence, and the rest of the room has no window at all. By late afternoon the end of the room away from the doors is dim, and the lights go on early.
The roof of the extension is flat or nearly so, and it spans the whole room. It is the biggest surface the room has, and it looks at open sky. It is also the one surface nobody has put anything in front of.
Straight up
A flat rooflight turns that roof into a source of daylight. One large pane over the dining end, or two smaller panes in a line, will light the room from above and bring the far corner into use. Where the ceiling has the height, a roof lantern gives the room a feature as well as light, because it lets the glass catch the sky from several directions at once.
On a flat roof, a rooflight sits on an upstand, a raised kerb that keeps the glass clear of standing water, and the glass sits tilted slightly so rain runs off. We finish the inside, so the opening ends in a clean plastered or boarded splay.
Rooflights have a vocabulary of their own, and it helps to know the words before the survey. The glossary below explains the ones you are most likely to hear when we talk through the options for your extension. The details of each product are on the flat roof rooflights and roof lanterns pages.
Think too about what the room is for. A kitchen and dining space wants light across the table and the worktop, so the glass goes over those. A family room wants it where people sit. A utility room or a boot room needs only enough to work by. Matching the size and position of the glass to what happens beneath it avoids both a dark room and a glare in the wrong place, and it is the first thing we talk through on site.
Rooflight words worth knowing
Upstand
A low raised kerb on a flat roof, which the rooflight sits on and which keeps it clear of the water.
Kerb
The frame, in timber or insulated material, that forms the edge of the roof opening.
Lantern
A glazed structure with vertical sides and a pitched or pyramid top, set above a flat roof.
Splay
The angled inside face of the opening that carries daylight from the glass into the room.
Insulated glazing unit
Two or three panes sealed together with a gap between them to hold heat in.
Trimmer
A timber added across the roof structure to frame the opening where rafters have been cut.
A bathroom boxed in by next door
The smallest room in the house, and the most closed in.
Sideways
A bathroom added into a loft, or fitted into the corner of a first floor, can end up with a single frosted window facing a neighbouring wall. It is small, high and fixed. The room gets enough light to find the towels and not enough to feel clean, and the extractor fan is left to deal with the damp that has nowhere else to go.
Side windows are limited by what stands next to them. A wall a couple of metres away will take a good share of the light a bathroom window could have had, and privacy glass takes more of it again.
Straight up
If the bathroom is under a sloping roof, a roof window can replace the side window altogether. It lights the room from above, opens for ventilation and can be fitted with obscure glass so nobody sees in, and nobody needs to see out because the view is of the sky.
If the bathroom is on a middle floor with a loft above it, a sun tunnel carries daylight down through the roof space in a mirrored tube. The diffuser in the ceiling spreads it evenly over the room. Neither option depends on the wall outside, and both leave the bathroom brighter than any side window could.
A bathroom is also where energy and moisture matter most. Roof windows for existing homes must meet the heat-loss limits in Approved Document L of the Building Regulations, which are 1.4 W/m²K or WER band B. Units chosen for a bathroom should also be rated for humid rooms, and the survey covers that. If the job needs a Building Control notification, that is something we send.
Shefford sits in Central Bedfordshire, and the council's building control pages explain how notification works.
Privacy can decide the choice. An obscure or frosted pane keeps the bathroom private whichever way it faces, and a roof window is angled upwards so nobody can see into it from the street. Condensation is managed by a good fan and a unit with a warm edge, which keeps the glass surface from chilling. We talk through both when we visit.
Verdict: for a Shefford bathroom with a small window facing a wall, a roof window or sun tunnel gives better light than any enlargement of the side opening could.
Planning where Shefford has a conservation area
Planning decisions in Shefford are made by Central Bedfordshire Council, whose planning and building pages sit at centralbedfordshire.gov.uk. Its heritage pages list a conservation area for the town. The boundary and the rules attached to it are for the council to describe, so read its pages before deciding where a rooflight should go.
Standing inside a conservation area is not, by itself, enough to take permitted development away; an Article 4 direction can do that. Ask the planning team whether your street has one. The permitted development conditions for rooflights are covered in our planning guide, and nothing is ordered until you know where you stand.
A listed building is a separate matter again: changes to its roof need listed building consent. If your house is old, ask about its status at the outset, because it changes which products are suitable and how the application is made.
Reaching Shefford from Milton Keynes
A survey here is a half-day visit rather than a trip, with the run east from Milton Keynes at 20.8 road miles and roughly 28 minutes of driving. Clifton, Meppershall and Henlow are neighbours, so a single run can take in a few streets.
The council's main offices at Priory House in Chicksands lie immediately west of the town, handy if you want to talk to the planning team face to face. Quick questions are best asked by message or email, and we are happy to help you word them.
The survey itself takes in the roof from outside, the loft from inside where there is one, and the room below. Allow a little time at the end for questions, because the best moment to change your mind about a position is before the quote is written.
Which roof, which rooflight
The roofs in Shefford vary from steep and old to flat and new, and no single product suits all of them. On a historic roof with a slate or clay tile covering, a conservation rooflight is the quieter choice. Over a flat extension roof, choose a lantern or a flat rooflight. In a loft with usable headroom, a roof window; in a room too small or too enclosed for a window, a sun tunnel.
When it is unclear which of these suits your house, the survey will settle it. We look at the roof, the structure beneath it and the room that wants the light, then advise on the option that works best. Larger glass lets in more light but needs a stronger opening, and smaller glass is gentler on the roof. The balance is a decision we make with you, room by room.
Position matters as much as product. A rooflight near the middle of a room spreads light evenly. One close to a wall lights the wall, which can be exactly what a dark corridor needs. In a bathroom, put a roof window over the bath or the shower and the light lands where it is wanted. Think about where you stand, sit and work, then ask for the glass to be put above that spot.
The survey and the written quote
The survey is free. Where there is a loft we climb into it, check the rafters or joists, measure the opening and see how the new unit meets the covering. You receive a fixed written quote that does not change on the day, and the fitting meets the Building Regulations in force on the day.
Fitting a single rooflight takes one or two days, the inside is finished and tidy, and a 10-year guarantee on the workmanship is given in writing. If you run a shop, office or workshop in Shefford, small commercial jobs are welcome. A booking can be made on WhatsApp at 07880 284133, through info@vertexskylightsmiltonkeynes.co.uk, or from the quote form.
Shefford questions
Are the old market streets of Shefford a conservation area?
Yes. The council's heritage pages list one named for the town. Ask its planning team whether your house falls inside it and whether any extra controls apply.
Can a rooflight go on a flat extension roof in Shefford?
Yes. A room with a flat roof and a fence or wall at its windows takes a flat rooflight or, where the ceiling allows, a roof lantern. The survey checks the structure and the fall of the roof, and the quote covers the upstand and the finish inside. See flat roof rooflights for the options.
