Lead Paint in Homes in the UK: Spot It, Test It, Deal With It
If your home was built before 1970 and still has layers of old paint, some of it may contain lead. Lead paint that is intact and left alone is a low risk. The danger comes when it flakes, wears into dust or is disturbed by sanding, scraping or burning off. The safe route is to know where it is likely to be, confirm it before you start any work, and then either leave it, seal it in or have it dealt with using low-dust methods.
This guide covers which homes and surfaces are most likely to be affected, how to identify suspected lead paint, what UK rules apply to work on it, and what to do next. It is written for homeowners, landlords and property managers across Cornwall and the South West, and the rest of the UK.
TL;DR
Lead paint may be found in homes built before 1970, mostly on windowsills, bannisters, door frames, doors and metalwork, often under newer paint.
Appearance gives clues but cannot confirm lead. Home test kits can give a wrong answer, so treat any pre-1970 paintwork as suspect before you disturb it.
Paint in good condition is best left alone or covered with modern non-leaded paint. Never use dry sanding, blow lamps or gas torches on it.
If removal is needed, use low-dust methods, protect the room, wear the right respiratory protection and keep children and pregnant women away.
Anyone doing the work as an employer has legal duties under the Control of Lead at Work Regulations 2002, and clients should tell contractors where lead paint is.

Why lead paint is still a live issue in UK homes
Lead compounds were used for decades as both pigment and drying agent in paint. Most lead-based paint was banned from sale to the general public in the UK in 1992, with exceptions for specialist uses such as historic buildings and artwork. Modern household paints do not contain added lead, so a newly built home will not have it.
The problem is the paint that was already on the walls and woodwork. Old coats do not vanish when you redecorate. They sit underneath, and a house that has been repainted several times can carry a lead layer you cannot see. Government guidance says lead paint may be found in homes built before 1970, and that it can still be present beneath newer non-leaded paint, notably in Victorian properties that have never been remediated.
That matters in Cornwall and the wider South West, where a large share of the housing stock is Victorian, Edwardian, interwar or older: terraces, farmhouses, cottages, chapels converted to homes and period seaside properties. If you live in one of these and are planning to redecorate, the question is not whether to worry, but whether to check first.
Where lead paint is most likely to be
Lead was favoured for hard-wearing, glossy finishes, so it is concentrated in the places that took the most wear and weather. According to the UK Government’s public guidance, look first at:
windowsills and window frames
bannisters and staircases
door frames and doors
metalwork, such as railings, gates and old radiators
Exterior ironwork and guttering from the era are also common candidates. Walls and ceilings painted in matt emulsions are less likely to be the issue than gloss and undercoat on joinery, though a thick build-up of old coats anywhere deserves caution.
A quick age guide
Home built | Likelihood of lead in old paint | What to do before redecorating |
Before 1920s (Victorian, Georgian, older) | High, especially on joinery and metalwork | Assume lead is present on original woodwork and treat as such |
1920s to 1960s | Possible, particularly on gloss-painted woodwork | Assume possible, avoid dry sanding, consider testing |
1960s to 1970 | Less likely but possible | Check original paintwork before disturbing it |
After 1970 | Lower risk, though old paint can be reapplied or used in refurbishments | Use normal good practice, test if in doubt |
New builds | Modern paints do not contain added lead | No specific lead concern |
The table is a rule of thumb based on the government’s pre-1970 guidance, not a guarantee in either direction. A 1950s house can have a 1900s door fitted, and a modern extension can sit beside a Victorian original.
How to identify suspected lead paint
You cannot confirm lead paint by looking at it. You can, though, build a reasonable picture of the risk.
Start with the building and the paint
Age of the property. Pre-1970 is the working line. The older the house and the more original the joinery, the higher the odds.
Original paint layers. Thick, built-up paint on windows, doors and stairs suggests many coats, and the oldest may be leaded.
Condition. Flaking, chalking, peeling or crumbling paint is where risk rises, because it creates dust and flakes that children can handle or swallow.
The Society for the Protection of Ancient Buildings (SPAB) notes that old lead paint may be creamy or soft in colour, can develop fine oblong cracking, and can feel heavier in detached samples. These are hints only. Plenty of non-leaded paint looks tired and cracked too.
Testing: what works and what does not
The SPAB says the presence of lead can be confirmed with a DIY test kit or more sophisticated analysis. The government’s public advice is more cautious: internet test kits can be used to sample paintwork, but they are not accurate and may give a false answer.
In practice that means:
A kit that shows a positive result is a good reason to take precautions.
A kit that shows a negative result on an old, many-layered surface should not be treated as permission to dry sand. The kit may only have reached the top coats.
For a definitive answer on something important, such as a nursery, a whole-house renovation or a listed building, ask for laboratory analysis through a qualified surveyor or specialist.
If a child has an elevated blood lead level and paint is a likely source, the same government guidance says the local authority or housing association may be able to sample the paint.
The simplest approach on any pre-1970 home is to assume lead is present on original joinery and work accordingly. It costs little and removes the guesswork.
The health risks, in plain terms
Lead builds up in the body. The World Health Organization has stated that there is no safe level of lead exposure. Government guidance says high exposure can damage the brain and kidneys, and that children exposed in early life may have a lower IQ, behavioural problems or nerve damage. Children may also breathe in dust and fumes during old-paint removal, or swallow paint flakes.
Lead paint becomes a significant hazard when it is degraded, flaking or disturbed during renovation, because that creates dust or fumes that can be inhaled or ingested. That is why the common DIY habits are the dangerous ones: dry sanding a door, burning off a windowsill, or scraping a sash window with the family at home.
If anyone in the household is pregnant, the safest course is to keep them out of the work area entirely. Our guide to painting while pregnant sets out what the NHS says. Concerns about a child’s exposure should go to your GP, who can arrange a blood lead test.
What to do if you suspect lead paint
Option 1: leave it alone
If the paint is in good condition, the government’s advice is to leave it undisturbed or cover it with non-leaded paint. A sound, intact coat of modern paint over old lead is a reasonable, low-risk finish. This is often the right answer for woodwork that is not worn or damaged.
The SPAB goes further for old buildings: the presence of lead paint does not justify stripping out historic joinery. If you have original sash windows, panelled doors or a period staircase, the aim is usually careful preparation and overcoating, not replacement. For a sensitive, conservation-first approach to historic timber, see this guide to conservation-first historic wood restoration.
If your home is listed, check what is allowed before changing finishes. Our guide to painting rules for listed buildings explains how to avoid enforcement problems.
Option 2: overcoat after careful preparation
Where the surface is sound but dull or marked, light preparation with wet methods, followed by primer and modern paint, seals the old coats in. Keep the work damp, avoid creating dust, and clean up with wet wipes or a suitable vacuum rather than a brush.
Option 3: remove it
Sometimes removal is genuinely needed: paint is flaking badly, a surface is being replaced, or the substrate is failing. The HSE says to use methods that minimise dust and fumes: chemical strippers, wet abrasive paper and on-tool extraction. It specifically says to avoid blow lamps and gas torches, which produce lead fume.
Practical steps from HSE guidance for the work area:
Keep children and pregnant women away from the room and its surroundings for the duration.
Remove or cover soft furnishings and surfaces with plastic sheeting.
Wear disposable overalls and an FFP3 mask, the respiratory protection HSE sets out for old lead paint work.
Wash hands and forearms thoroughly before eating, drinking or smoking, and manage contaminated clothing so dust does not travel to other rooms or vehicles, as UK government guidance advises.
Clean surfaces thoroughly afterwards, wet rather than dry, and bag waste carefully.
Our wider guide to removing old paint safely covers general preparation, and our piece on the role of safety in painting explains the habits we expect on any job.
The Painting and Decorating Association’s guidance for professional decorators recommends a step-by-step approach: if lead is suspected, test the surface, and if it is confirmed, consider employing professional decorators.
UK rules on lead paint
There is no single law that requires a homeowner to strip lead paint from their own home. The rules that matter are about sale of paint and about work done by employers and contractors.
Sale of lead paint. Most lead-based paint was banned from sale to the general public in 1992, with specialist exceptions.
Work on existing paint. The Control of Lead at Work Regulations 2002 require employers to protect employees from lead exposure by assessing, controlling and reviewing work involving potential lead hazards, according to HSE guidance.
Enforcement. HSE can recover the costs of time spent dealing with material breaches of health and safety law through its Fee for Intervention scheme.
Client duties. Professional guidance states that clients have a statutory duty to advise designers and contractors about the whereabouts of lead-based paint before a project.
What this means for landlords and property managers
If you commission work on a pre-1970 property, tell the contractor what you know about its age and paint history, and share any test results. That is how the contractor can plan for lead properly. Landlords will find more on obligations in our guide to landlord responsibilities for painting. Managers of shops, offices and other premises can read about our commercial painting service.
Our perspective: treat old paint with respect, not fear
We work in Cornwall and the South West, where older homes are the norm, so old paint is part of nearly every job. Our view is simple: most lead paint in a house is not an emergency, and the worst outcomes come from rushing the preparation.
We would always rather a homeowner asked the question before a job than after. If a property is from before 1970 and we are asked to redecorate woodwork, we think about dust first: what will be disturbed, who is in the house, and whether overcoating a sound surface gets the finish the customer wants without stirring anything up. Often it does. A well-prepared, well-primed and properly finished surface looks better and lasts longer than one that has been hacked back.
Where paint does need to come off, we favour controlled methods over speed. Airless spraying of new coats is efficient and gives an even finish, but it is only as good as the surface under it, so preparation is where the time goes. We keep communication clear, so you know what we are doing in your home and why.
Two habits we would pass on to anyone: never dry sand old gloss, and never assume a clean-looking window frame is harmless just because it has been painted over many times.

Choosing between leaving, overcoating and removing
Use this as a starting framework for a pre-1970 property.
Situation | Usual sensible approach |
Sound paint, no planned work | Leave it alone, monitor for flaking |
Sound paint, redecorating | Wet clean, light wet preparation, prime and overcoat |
Flaking or worn paint on joinery | Low-dust removal of loose material, then prime and repaint |
Heavy build-up stopping windows or doors closing | Controlled removal with chemical stripper or on-tool extraction |
Family with young children or someone pregnant | Keep them out of the work area, prioritise damaged paint first |
Historic or listed joinery | Conservation-minded repair and overcoating, check consent requirements |
Exterior surfaces follow the same logic. Old railings, gates, window frames and fascias can all carry lead paint, and weathering makes it flake. Our external structure painting tips give practical advice on preparing and finishing them. Jet washing old paint can spread flakes into soil and drains, so think about where debris will go before you start.
Redecorating a pre-1970 home: a sensible order of work
Find out what you have. Note the age of the house, which paint is original and what condition it is in.
Test if it will influence your decision. Use a kit as a prompt for caution, not as a clearance.
Plan the job around dust. Decide whether you will overcoat or remove, and which rooms the family can stay out of.
Prepare the room. Sheet floors, cover or remove furnishings, and seal the door to the rest of the house.
Use low-dust methods. Wet abrasion, chemical strippers or on-tool extraction.
Clean as you go. Wet wiping and suitable vacuums, no dry sweeping.
Seal and finish. Prime and apply modern paint so the old layers are encapsulated.
Wash and change. Hands and forearms washed, work clothes bagged and washed separately.
If you are buying an older house or taking on a renovation, sort the paint plan before any major work. For new homes, you can ignore lead but should still read about new build painting snags. For general quality benchmarks, see painting industry standards.

FAQ
Is lead paint in my home dangerous if it is not flaking?
Intact paint in good condition is generally not a problem if it is left undisturbed or covered with non-leaded paint, according to government guidance. The risk comes when it deteriorates or is disturbed by sanding, scraping or burning off. Keep an eye on high-wear areas such as windowsills and door frames.
Can I tell if paint is lead-based just by looking?
No. Creamy, soft-looking paint with fine oblong cracking can be a clue, but only testing can confirm lead. Home kits can give a false answer, so for anything important ask a qualified professional about laboratory testing. Treat original paint in any pre-1970 home as suspect until proven otherwise.
Can I paint over lead paint?
Yes, if the existing paint is sound. Government advice is to leave it undisturbed or cover it with non-leaded paint. Clean and prepare the surface with wet methods, avoid dry sanding, and prime before applying modern paint. Loose or flaking areas need careful low-dust removal first.
Do I have to remove lead paint from my house?
There is no general requirement for a homeowner to strip lead paint from their home. Removal is usually only worth doing where paint is damaged or work will disturb it. Employers and contractors working on it do have legal duties under the Control of Lead at Work Regulations 2002.
Is it safe to be at home while lead paint is being removed?
It is better not to be. HSE guidance says to keep children and pregnant women away from the work area, sheet off surfaces and clean thoroughly afterwards. If you must stay, keep the work room sealed off and avoid it until it has been cleaned.
