Short answer

Thames Water supplies Cirencester, and its water is among the hardest on this site, at 317 mg/l. Limescale builds up fast in combi boilers, cylinders and taps. Many homes in the centre date from before 1919, so some may still have lead pipes. A water softener needs notice to Thames Water first.

Plumbers in Cirencester by service

How hard is the water in Cirencester?

Very hard. The Thames Water postcode checker gives 317 mg/l of calcium carbonate for the Cirencester supply zone, or 22.2 degrees Clark.

Thames Water calls anything over 300 mg/l very hard. It says hardness comes from the rock at the source, and it cannot change it.

Building rules set the line at 200 mg/l. Above it, Approved Document L asks for treated feed water to a water heater. The hot side of a combi boiler needs the same, to slow scale. Ask each plumber what scale reducer the quote includes.

Does a Cirencester home need a water softener?

It is your choice, but there are rules. A softener that uses water to regenerate is on the list of fittings in regulation 5 of the Water Fittings Regulations. You must tell Thames Water before the plumber fits it.

Thames Water advises against softened water for drinking or cooking. If you fit a softener, keep one tap on unsoftened mains water, usually at the kitchen sink.

A cheaper option is a scale reducer on the boiler feed only. It protects the boiler, but not the shower heads or the kettle.

Do old houses in the centre have lead pipes?

Some may. The Drinking Water Inspectorate says a home built before 1970 may have lead pipes. In the Cirencester Central area, 44.3 per cent of homes on the Council Tax list date from before 1965.

In Cirencester South the figure is 32.7 per cent, and in Cirencester East and Stratton it is 38.7 per cent.

To check, look at the pipe by your inside stop tap. Lead is dull grey, often with a swollen joint, and shows bright metal when you scrape it with a coin. You own the supply pipe from the outside stop valve to the house.

What about pipework on listed houses and in the conservation areas?

Cirencester has four conservation areas, and the town centre is outside the Cotswolds National Landscape. In a conservation area, a new soil and vent pipe on a wall that faces a road is not permitted development.

On a listed house, a new bathroom, a waste pipe through an old wall or a new vent can all need listed building consent. Ask Cotswold District Council before the work starts.

Questions

Who do I call about a burst main in Cirencester?

Thames Water supplies the town. A leak on the pipe before your outside stop valve is for the water company. A leak inside your boundary is for you and your plumber.

Is the lead level in Cirencester water safe?

In 2025, Thames Water took 8 lead samples in the Cirencester zone, and each was under 0.9 micrograms a litre. The legal limit is 10. Your own pipes can still add lead.

Does a new unvented cylinder need building control?

Yes. Approved Document G says an unvented hot water cylinder over 15 litres must be fitted by a competent person. The work must also be notified to building control.
