Posted on Google HarryTrustindex verifies that the original source of the review is Google. Our boiler suddenly stopped working on a freezing morning.

Recommend very highly!Posted on Google Serena ReidTrustindex verifies that the original source of the review is Google. Came home from on holiday on 03/01/26 to the boiler not working - not heating or hot water - on one the coldest days of the winter. Was calling round desperately to find emergency plumber at 8pm on a Saturday. Despite calling multiple plumbers, none could come until the Monday...Then there was Alex! He came round on that Saturday night, found the problem and made a plan to replace the broken part. He was AMAZING! He was upfront about costs, timings, issues and part sourcing. Within 72 hours (part sourcing and error code issues that, were unrelated to Alex, were an issue) We had our boiler back working. Very grateful to Alex, who was so in demand and worked like trooper, would 100% recommend himPosted on Google Jasmine KershawTrustindex verifies that the original source of the review is Google. Can’t recommend highly enough! Alex arrived quickly and fixed our leaking water heater in a jiffy. He gave some great, honest advice and charged exactly what he said he would (a very good price). Efficient and friendly - will definitely be saving his number for future plumbing crises.Posted on Google Leo JasminTrustindex verifies that the original source of the review is Google. Alex sorted out all the problem in my boiler, great service and friendly, highly recommended for boiler and heating problems👍

Frequently Asked Questions
What is included in a domestic drain installation assessment?
We review the intended use, route, access and existing connections before defining the proposed domestic work. The quotation then states the installation scope, materials, access assumptions and testing for the installed section.
When might a new drain installation be appropriate?
Planned installation may be appropriate for an alteration, a new domestic waste connection or replacement of an agreed damaged section. The right solution depends on the property and must be assessed before work is specified.
What type of drainage work does this page cover?
This page covers planned domestic waste and drain installation work that can be defined after a property-specific assessment. It does not claim commercial, civil, stormwater, soakaway or broad infrastructure capability.
How long does a drain installation take?
Duration depends on the route, access, ground or building conditions, materials and testing required. We provide a likely programme after the installation scope has been assessed and agreed.
How are installation materials selected?
Materials are selected for the agreed use, route, connection and site conditions. We state the proposed specification in the estimate rather than promising a particular material before assessment.
Can every installation be completed without excavation?
No. Excavation or opening-up requirements depend on the route, access and connections. We do not promise a trenchless or no-dig installation before the site has been assessed.
How do you limit waste and disruption?
We plan access and sequencing around the agreed route and explain likely disruption before work. Any claim about sustainability or a special environmental system would require a separate, verified specification.
Do you claim commercial or civil drainage installation?
No. This page is intentionally limited to assessed domestic drain installation work. Commercial, civil and specialist drainage systems are not advertised here without separately verified capability.
How much does a drain installation in London cost?
Cost depends on the route, access, materials, connections and testing required. We provide a transparent estimate before work begins, with no hidden additions to the agreed scope.
How should a newly installed drain be maintained?
Use drains only for their intended waste, avoid fats and unsuitable items, and follow any project-specific aftercare. If flow changes or a blockage recurs, arrange an assessment instead of mixing chemical cleaners.
