What usually happens instead
Most building work is announced by a skip. The first a street knows about it is a lorry at seven in the morning, and by the time anyone has worked out whose house it is, two neighbours have already decided the job is going to be a nuisance.
The homeowner is not being inconsiderate. They have a builder, a start date that moved twice, a party wall surveyor and a mortgage, and writing to the street is the one task with no deadline attached to it. So it slips, and the relationship with the people who will be living beside the work for four months starts from a standing start. On one of our own busier jobs the letter was the thing that slipped. We started on a street we had not yet won over, and inside the first week a delivery driver had damaged a planter and a subcontractor had left rubbish on the pavement, with the neighbours finding out about both by walking past. None of it was serious. All of it landed on people who had been told nothing, and who had no way to tell us.
The letters that do go out are usually better than nothing and worse than they look. They arrive once, at the beginning, before the programme has settled. They name a finish date that turns out to be optimistic. They carry a mobile number that belongs to a builder who is up a ladder. And three months in, when the thing the neighbour actually wants to know is whether Thursday is the concrete pour, there is nothing to consult.
What to put in the letter
Seven things, in this order, will cover almost every job.
Who you are and which property the work is at, so nobody has to guess. What the work is, in one sentence and without jargon, because "a rear extension and a loft conversion" tells a neighbour more than the planning reference does. When it starts and how long you expect it to take, with an honest range rather than a date you will be held to.
Which parts will be noisy and roughly when, which is the single most useful line in the letter. The working hours you will keep, checked against your own council's published hours rather than assumed, because they vary between neighbouring boroughs and our guide to building work hours sets out how much. Where the skip, the scaffolding and the deliveries will be, and whether parking will be affected. And a way to reach someone, with a note of how quickly you will come back to them.
Then one short line offering to talk before it starts. A surprising number of problems, from a shared drain to a neighbour who works nights, only surface because somebody asked.
One thing the letter does not replace. Where the job involves a party wall or party structure, or excavation near a neighbour's foundations, the Party Wall etc. Act 1996 sets out formal notices with their own timescales, and the government's guide to party walls and building work explains when one is needed. Serve those in their own right and send the letter alongside them.
A letter you can copy
Replace everything in square brackets and delete what does not apply.
Dear neighbour,
I live at [your address], and I am writing to let you know about building
work starting there on [start date].
The work is [a short plain description, for example a single-storey rear
extension and a loft conversion]. I expect it to take about [number of
weeks or months], so it should finish around [approximate end date]. I
will let you know if that changes.
The builder is [company name]. Their site team will be on site on
[working days], and they will keep to [borough or council name]'s
permitted hours for noisy work, which are [days and times as published
by your council].
The noisiest stages are [for example demolition of the rear wall, and
breaking out the old concrete floor]. I expect those to fall in
[approximate weeks or dates], and I am sorry in advance for those weeks.
I will let you know before each of them starts.
A skip will be [where the skip will stand], from about [dates]. The
scaffolding goes up around [date] and comes down around [date].
Deliveries will arrive [when], and [say here whether parking or access
will be affected, and for how long].
If anything goes wrong, or the work affects you in a way I have not
thought of, please contact [name and role] at [email address or the
route you want people to use]. I will come back to you within
[for example one working day], and if something needs fixing I will tell
you what is being done about it.
If it would help to talk before the work starts, I am happy to. You can
reach me at [email address].
Thank you for your patience.

What the letter cannot do
It is a one-off. Everything in it was true on the day it was printed, and building programmes move. The scaffold goes up a fortnight late, the noisy fortnight lands in a different month, the skip moves to the other side of the road. Nothing in the neighbour's hand reflects any of that, and by week six the letter is a historical document sitting in a drawer, if it was kept at all.
It goes out of date silently. There is no mechanism in a letter for telling people that Thursday is now the pour, that the water is off on Tuesday morning, or that the crane lift has moved to Saturday. Those are precisely the things a neighbour needs a day or two of warning about, and they arise weekly.
Nobody can reply to it. A letter is one-directional by nature. The neighbour reads it, decides they are not going to bother the homeowner about the dust, and either lets it go or, three weeks later, telephones the council. Our guide to handling a neighbour complaining about your building work covers what happens next.
And it leaves no record. Sending it does not show that anyone read it, that a problem was raised, or that anything was done. When there is a dispute in month four about whether the dust was reported and ignored, the letter is no help to either side: the neighbour cannot show they raised it, and the homeowner cannot show they answered.
What the letter was standing in for
Look at what the letter is trying to be. It is trying to be a place where the people around a building site can find out what is happening and say when something is wrong, and it is a sheet of paper, so it manages that for about a fortnight. Everybody involved then spends four months arguing about the past with nothing to check it against: the neighbour is sure they raised the dust twice, the builder is sure nobody mentioned it, and neither of them wrote anything down. A shared, dated record of what was announced, what was reported and when it was dealt with settles it for the neighbour, the homeowner and the builder at the same time, because all three are reading the same record. On Noisy Neighbour it costs £5 per site per week, and neighbours join free.
Where the notices carry on
Send the letter, and put the site's web page address on it. Each site gets a public page with a printable QR sheet for the hoarding, the scaffold or the front of the property, and scanning it opens the page, which shows who is doing the work, the working hours and the notices coming up. There is no password and nothing to install, and neighbours who want the notices by email join the page with an email address.
From then on, each thing the letter could not carry is posted once by the site team, emailed to every neighbour who has joined, and shown on a calendar anyone with the link can see. The types are the ones a street cares about: noisy work, deliveries, skips and waste collections, milestones such as the scaffold going up or coming down, and utility interruptions. The concrete pour on Thursday is announced on Tuesday, to everyone, rather than mentioned to whoever happens to be in the front garden.
The reply route is the other half. A neighbour reports a problem by choosing a category, describing it and adding a photo if it helps, and the site team is notified straight away and answers in the same thread. Each issue records who raised it, when it was raised, when it was acknowledged, when it was resolved and whether the neighbour confirmed the fix, with the average response and resolution times shown on the page, so nobody has to take anyone's word for how the last complaint went. What a street is entitled to know, and a message a neighbour can send asking for a page to be set up, is on our page for neighbours.
